Introduction
LeakTracer is a small tool I wrote when checking a C++ program for memory
leaks. I couldn't get dmalloc to display what I wanted, and I just saw the
__builtin_return_address gcc-extension mentioned.

To use LeakTracer, run your program using the provided LeakCheck script. It
uses the LD_PRELOAD feature to "overlay" some functions on top of your
functions (no recompile needed). If your platform does not support LD_PRELOAD,
you can add the LeakTracer.o object file to the objects in your Makefile and
run your application. 

LeakTracer uses gdb to print out the exact line where the memory was allocated
and not freed - this of course means you have to free all dynamically
allocated data. LeakTracer also overrides the global operator new and operator
delete - this will give problems if you override them as well.

LeakTracer traces only new/new[] and delete calls - it does not look at
malloc/free/realloc.

Here is some example output:

Gathered 8 (8 unique) points of data.
(gdb)
Allocations: 1 / Size: 36
0x80608e6 is in NullArcableInstance::NullArcableInstance(void) (Machine.cc:40).
39      public:
40          NullArcableInstance() : ArcableInstance(new NullArcable) {}

Allocations: 1 / Size: 8
0x8055b02 is in init_types(void) (Type.cc:119).
118     void init_types() {
119         Type::Integer = new IntegerType;

Allocations: 1 / Size: 132 (new[])
0x805f4ab is in Hashtable::Hashtable(unsigned int) (ea/h/Hashtable.h:15).
14          Hashtable (uint _size = 32) : size(_size), count(0) {
15              table = new List [size];

[...]


Requirements
You need Perl5 and gdb installed to run the leak-analyzer. You need gcc -- I
currently use 2.95 but have used it with previous older versions without
problems.
You also need to run this on an architecture which supports
__builtin_return_address arguments that are greater than 0 - there may be
some problems on MIPS there. 

So far this code has been tested under Linux 2.2, x86 system, Solaris and
HP-UX.

Installation
Just type make. There is no install target; you should put LeakTracer
some place you can remember.

Since version 2.0, it is possible to preload the LeakTracer object on
architectures that support LD_PRELOAD (this is at least Linux and probably
others -- please report success/failure). This means it is much easier to use
the program: you do not need to relink your program with LeakTracer.o.

In case your platform does not support LD_PRELOAD, you can use LeakTracer in
the old pre 2.0 way: add LeakTracer.o to your object files -- at the very end
of them (also after -llibrary lines).

In any case your application must also be compiled with debugging enabled
(i.e. -g).


Running with LeakTracer
If you are using the shared object, run the LeakCheck script. This script
should stay in the directory where you install LeakCheck -- it will search for
LeakTracer.so file there and load it. E.g.:

~/src/LeakTracer/LeakCheck yourApplication

(if you put LeakTracer in ~/src/LeakTracer/)

Run your application as normal, performing tasks that you want to be traced
for memory leaks. While the application runs, LeakTracer will write data about
memory allocation to the file "leak.out" in the current directory. You can
override the location of that file by setting the LEAKTRACE_FILE environment
variable.

If you cannot use LD_PRELOAD, just run your application as normal after
relinking it. It will also produce a "leak.out" file when it finishes.

Detectable errors
LeakTracer is capable to detect the following problems with your program

  1) memory which is allocated but not freed
  2) (limited support for) overwritten memory at the end of the allocated
     block  ( reason = 1 )
  3) memory which is tried to be deleted but which is not allocated
     (either because of a garbage pointer or twice deletion)
     (reason = 2)
  4) memory which is allocated with new[] but deleted with simple delete
     and vice versa (reason = 4)

For the last three problems, LeakTracer can abort() your program if you
tell it so; the resulting core-dump allows to debug the problem. By default,
only the overwrite memory condition results in an abort of the program
because it is inherently critical. The two other conditions are not critical.
You can influence what LeakTracer does with the environment variable
   LT_ABORTREASON
which you can set to some numeric value which is the result of the
sum of the reasons you find in the parentesis in the enumeration above.
To abort on any reason, for example, you would set LT_ABORTREASON to 7.

Analyzing output
You should then run leak-analyze, since looking at the raw leak.out file will
not help you much. To run leak-analyze, you need Perl as well as gdb
installed (any version of gdb will do). For example:

leak-analyze myprog leak.out

You don't have to specify the leak.out filename if you just use the default
one. leak-analyze will run gdb on the file, sending it a number of commands
that will show the source lines with the memory leaks.

leak-analyze should show you something like this:

Gathered 2 (2 unique) points of data.

#-- Alloc: Different allocation schemes
alloc here :0x80485b7 is in main (test.cc:6).
5
6               int *wrong = new int[10];
..free here :0x80485d9 is in main (test.cc:11).
11              delete wrong;

#-- Leak: Allocations: 1 / Size: 168 
0x8048593 is in main (test.cc:3).
2       int main() {
3               int *array = new int [42] ;

#-- Leak: Allocations: 1 / Size: 4 
0x80485a5 is in main (test.cc:4).
3               int *array = new int [42] ;
4               int *foo = new int;
This means that total of two allocations happened, in two different places.

First a delete error is shown: you allocated some memory using new[] but you
freed it using delete. leak-analyze will show where you allocated the memory and where you freed it.

Afterwards each allocation is shown in turn. There was 1 allocation from this
line of code (test.cc:3), and it was 168 bytes in size. Note that of the two
lines of code shown, it's the bottom one that created the allocation.

That's all there is to it - now you should find those memory leaks, fix them
and rerun Leak tracer.


Shared libraries and objects
If you want to analyze the leaks in shared libraries in your file, it may be
necessary to make leak-analyze run your program and thus load the shared
libraries before searching for addresses.

To do that, run leak-analyze with the program name, leak name AND another
argument which is where to set the breakpoint, e.g.:

leak-analyze myprog leak.out main

This will make leak-analyze tell gdb to set a breakpoint on "main" and then
run the program. After the analysis is complete, the program will be killed.

If you want to load some shared libraries, you can set a breakpoint on a
different location, e.g. main.cc:42 if you know that once line 42 is reached,
all shared objects have been loaded.

If your program needs some command line arguments, supply them after "main".

Licensing
LeakTracer is public domain (i.e. do with it whatever you feel like).

February 23, 1999       	v1.2 - Oops, forgot to free() the memory..
February 26, 1999		v1.3 - allow delete 0
March 27, 1999			v1.4 - Allow %p format without leading 0x for non-GNU 
                                       libc. Option to leak-analyze to run the program.
July 21, 1999           	v1.5 - Fix for the above suggested by Alan Gonzalez
August 21, 2000			v1.6 - use a destructor instead of 
                                       __attribute__(destructor)
November 19, 2000               v2.0 - Rewrite by Henner Zeller introduces LD_PRELOAD
                                       and much more
February 27, 2001               v2.1 - Further update by Henner: optional thread safety,
                                       choose what should make LeakTracer abort(), better
                                       tracing of delete on non-new'ed pointers
March 2, 2001                   v2.2 - Another updated by Henner: hash table to increase
                                       performance with many allocations
June 13, 2001                   v2.3 - Made LT more resistant to being called before init
                                       and after destruction

/**
*
*	OpenGL viewer for RadiosGL rendered scenes
*
*	Created 1-14-2000
*	Mods:
*		Jason Rohrer	1-15-2000		Added timer function to make keyboard
*										interaction smoother and more intuitive
*
*		Jason Rohrer	1-18-2000		Moved SetMouse call from within mouse handler
*										to inside re-display function
*										SetMouse was posting a new mouse event too
*										quickly, putting the delta-angles back to 0
*										before the posted redisplay happened.
*
*										This made view motion jerky on the PC
*										Fixed it by only centering mouse when it leaves window
*										(or hits window border)
*										Added mouse capture to window on PC so that
*										mouse events outside window border are captured
*								
*										Added "o" key control to switch into fullscreen mode

 * 2001-September-15		Jason Rohrer
 * Created.
 * Changed to use normalized floating point coordinates.
 * Fixed some compile bugs.
 * Changed so that mouse released events are passed to all components.
 *
 * 2001-October-29		Jason Rohrer
 * Added support for focus, including mouse-release to focus.
 *
 * 2001-November-2		Jason Rohrer
 * Changed to send keyboard events only to focused components,
 * regardless of mouse position.

 * Modification History
 *
 * 2000-December-19		Jason Rohrer
 * Created.
 *
 * 2001-January-19		Jason Rohrer
 * Added support for multi-texturing.  Now a TextureGL no longer has 
 * an overall width and height (each layer can have a different size).
 * Also, a TextureGL no longer has an overall ID.
 * Got rid of an old, commented-out interface in the process.
 * Changed how multi-textures are blended.  Settled on using MODULATE
 * for all layers of the texture, since nothing else produces results
 * that are compatible with vertex lighting.
 *
 * 2001-January-30		Jason Rohrer
 * Changed to check for GL version 1.2 before using 1.2 features.
 * Now we assume multi-texture is defined (because of the availability
 * of glext), but we check that it is supported at runtime.
 * Moved enable() below ARB function name definitions.
 *
 * 2001-January-31		Jason Rohrer
 * Fixed even more compile bugs.  There's no need to do a multitexture
 * bind when setting texture data.
 * Removed extra checks for unneeded extensions, and fixed more compile bugs. 
 * Fixed a bug in initMultitexture().
 * Fixed a bug in disable().

	 * ERROR HANDLING:

	 * have to update with each future release.
	 *
	 * Our example here shows how to override the "error_exit" method so that
	 * control is returned to the library's caller when a fatal error occurs,
	 * rather than calling exit() as the standard error_exit method does.
	 *
	 * We use C's setjmp/longjmp facility to return
	 * control.  This means that the
	 * routine which calls the JPEG library must
	 * first execute a setjmp() call to
	 * establish the return point.  We want the replacement error_exit to do a
	 * longjmp().  But we need to make the setjmp buffer accessible to the
	 * error_exit routine.  To do this, we make a private extension of the
	 * standard JPEG error handler object.  (If we were using C++, we'd say we
	 * were making a subclass of the regular error handler.)

 * Modification History
 *
 * 2000-December-21		Jason Rohrer

 *
 * 2001-January-6		Jason Rohrer

 * 2001-January-10		Jason Rohrer
 * Made class serializable. 
 *
 * 2001-January-15		Jason Rohrer
 * Made copy() not-virtual, so it can be overridden by subclasses

 * implementation is invoked. 
 *
 * 2001-January-31		Jason Rohrer
 * Fixed a bug in copy().
 *
 * 2001-February-3		Jason Rohrer
 * Updated serialization code to use new interfaces. 
 *
 * 2001-February-4		Jason Rohrer
 * Rewrote the serialization code to send the image across as a byte
 * array with one byte per channel.  This will reduce the transfer size by
 * a factor of 8.  Keeping images in double format is convennient for image
 * creation, but the added quality never affects the end user anyway, so
 * there's no point in sending the extra data to a stream.
 * Removed an unused array allocation.
 *
 * 2005-February-21		Jason Rohrer
 * Made destructor virtual to avoid compiler warnings.

 * Created.
 *
 * 2004-August-6   Jason Rohrer
 * Fixed consistency bugs in test for in/out of sculpture status.
 *
 * 2004-August-22   Jason Rohrer
 * Added music parts.
 *
 * 2004-August-23   Jason Rohrer
 * Added function for getting number of pieces in sculpture.
 *
 * 2004-August-29   Jason Rohrer
 * Changed so that only pieces in sculpture are animated.
 *
 * 2004-August-30   Jason Rohrer
 * Optimization:  avoid object blending whenever possible.
 * Added function for getting piece position needed to recenter.
 * Weakened the power modifier curve.
 *
 * 2004-September-3   Jason Rohrer
 * Changed to use pure distance between pieces instead of gap for in-sculpture
 * test.
 *
 * 2005-August-22   Jason Rohrer
 * Changed so that isPieceJarred returns true only if jar force is increasing.
 * Added magnet mode to smooth piece pick-up and drop.

--Fixed bugs that caused post-explosion fade factors to become negative, which
  in turn caused boss explosions to linger on some platforms.

--Fixed zoom behavior when strafing.

--Added fade-in when enemies are created to avoid a visual pop-in.

--Added smooth turning when enemies switch targets.

--Changed so that pieces can be picked up while they are moving as a result
  of enemy fire.  This makes pick up less confusing and frustrating.

--Made bullet fade-out smoothly at end of range to avoid visual pop.

--Doubled piece pick-up radius to make picking up pieces easier.

--Fixed jerky piece pick-up and drop.

--Added mini-explosion graphics to indicate when damage is being done to boss.
  These graphics also change color to indicate the boss' health. 




Version 0.1    2004-September-1
--Initial release




Version 0.1.1-IGF-1  2004-September-3
(Final submission for first round of IGF 2005)

--Added fades to beginning and end of each sound effect to reduce clicks.

--Changed enemy logic so that they back off after they knock your ship back
  to the center.

--Made grid coloring in relation to boss position smoother and more detailed.

--Added grid coloring in relation to ship position.

--Improved logic that determines whether a piece is in or out of the collage. 




Version 0.1.2   2004-September-26

--Added a missing dependency to the GNU/Linux X86 makefile.

--Shortened Mac download file name to make Internet Explorer happy.




Version 0.2-IGF-2  2004-October-15

--Switched grab/drop key to 'D' to improve key layout (in between new strafe 
  keys).

--Parameterized grid size so that it can vary from level to level.

--Added a bullet limit that makes space-bar mashing ineffective.

--Made starting bullet shape much smaller in all levels to make its weakness
  more obvious.

--Added a portal object that appears after the boss is dead.  If you delay
  passing through the portal, you can explore the music Elements before moving
  on to the next level without being bothered by enemies.

--Added a zoom-in effect at the start of each level to give a quick overview
  of the level layout.

--Fixed a bug that resulted in keys getting "stuck" down.

"There are 11 levels to play as the hero Omega battles and defeats the Evil Forces controlling him. Based on the famous comic character, the hero uses hand-to-hand combat as well as an arsenal of weaponry and superpowers to complete each mission in the game. This game features several different styles of game play, including:  
Action- revolves around the hero fighting enemies in fierce battles.  
Puzzle Solving- requires the player to figure out mission puzzles, such as unlocking hidden doors and getting into a security system allowing the hero safe passage.  
Stealth- allows the player to avoid involving the hero in outright confrontation, and instead use a variety of stealth moves to knock out and evade enemy soldiers.  Some missions will be impossible to complete without using the stealth skills."Incorrect:

Transcend is an abstract shooting game with geometric, morphing graphics.
There are three levels.  In each level, the player guides a ship-like glyph 
around a grid.  Minor anti-glyphs (enemy objects) attack the player's glyph 
by shooting at it.  When the player's glyph is hit by an enemy projecile, it 
is knocked toward the center of the grid.

Players can increase the power of their projectiles by gathering elements
from around the grid and bringing them to the center.  The elements form
a visual collage, and each element also represents a section of music.
Thus, while powering up their projectiles, players are also arranging a piece
of music that plays in the background.  Anti-glyphs also attack the player's 
collage by shooting at it, and these attacks push elements away from the 
center. 

The player's goal in each level is to destroy the major anti-glyph, a large
enemy object that circles around the outskirts of the grid.  When the player
approaches the major anti-glyph, the anti-glyph attacks the player's glyph
with powerful projectiles.  The player must shoot the major anti-glyph many
times in succession to destroy it.  After the major anti-glyph has been
destroyed, a portal opens that allows the player to move on to the next level.


5. VIOLENCE 
--Violence Depicted:
--Includes depictions involving injury, damage, death, or destruction of the 
  following:

Humans:            Never
Animals:           Never
Creatures/Robots:  Frequently
Vehicles:          Never
Objects:           Never


--Describe specific instances of the above forms of violence, and the context 
  in which they occur:

The player shoots projectiles at abstract enemy entities.  These entities are
controled by the computer and behave autonomously, so they are best described 
as "robots" and not as "objects."  However, they do not represent robots 
specifically, but instead represent an abstract enemy force.  When enemy 
entities are destroyed, they morph into geometrical explosion displays and 
then fade away.
	
	
--To what extent can the player control the depictions of violence?

The player hits the SPACE bar to fire each projectile and aims projectiles
using the ARROW keys.  Thus, the player completely controls each act of 
violence.  However, the depection of the destruction (in other words, the
explosion graphics that are displayed in each case) are controled by the
computer.


--Describe how violent acts are rewarded in the game, i.e., is the player 
  rewarded for successfully completing, avoiding, or preventing acts of 
  violence, aggression, injury, or death?  Include specific instances of such 
  rewards, and the context in which they occur:

The player is rewarded indirectly for destroying minor anti-glyphs because the
player gets a break from enemy attacks until the next wave of anti-glyphs 
appears.  In other words, it is difficult to build an element collage while
anti-glyphs are attacking, so the player will benefit from destroying them.

The player is rewarded directly for destroying the major anti-glyph by gaining
access to the next level.


--Violent Sound Effects:
--Includes all sounds associated with violence, injury, pain, or death.

Violent sound effects heard or depicted:  Frequently


--Describe specific instances of these sound effects, and the context in which
  they occur:

Each projectile fired is accompanied by a musical note.
Each enemy explosion is also accompanied by a musical sound.
These sound effects are abstract and do not directly represent a violent act.


--Non-adversaries:
--Includes characters who are non-threatening or non-aggressive to the player,
  such as bystanders, pedestrians, and teammates.

Player can injure, damage, kill, or destroy non-adversaries:  Never


--Blood Effects:
--Includes all blood-like fluids, regardless of color or how they are depicted,
  such as puffs, splatters, pooling, or bloodstains.

Blood effects depicted:  Never


--Gore:
--Includes the mutilation of any organism (e.g., humans, animals, aliens, or 
  other creatures) by dismemberment, decapitation, burning, or other means, 
  and the depiction of burnt body parts, non-identifiable body parts or "gibs",
  guts, or severed limbs.

Gore depicted:  Never


--Post-Mortem Damage:
--Includes any damage that can affect the body of a dead organism (including 
  humans, animals, aliens, or other creatures) by shooting, burning, or other 
  means, utilizing blood effects, gore effects, rag doll physics, etc.

Post-mortem damage depicted:  Never


--Other:
--Please indicate whether the following themes, information, or actions are 
  present.

Crude or vulgar acts:                      Never
Acts of discrimination or racism:          Never
Sexual violence, rape, or attempted rape:  Never
Suicide:                                   Never
Torture:                                   Nevertranscend-0.3+dfsg2.orig/Transcend/doc/moondance/submission/screen5.png0000640000175000017500000041451210304371203024623 0ustar  pabspabs‰PNG

Transcend Description:
----------------------

Transcend is an abstract, 2D shooter.  The morphing graphics engine creates an 
alluring visual display.  Using musical power-ups, players simultaneously 
construct churning visual collages, arrange unique pieces of music, and 
strengthen their projectiles.  Transcend blurs the line between games and 
art---is it a video game or a multimedia sculpture?




-------------------
Transcend Features:
-------------------

 -- intricate, abstract visual style

 -- dynamic graphics that bloom and morph from one complex shape to another

 -- musical power-up system that lets you strengthen your projectiles while 
    also composing a unique piece of music

 -- novel collect-and-defend gameplay mechanics (no lives, health bars, or 
    "game over" screens)

The motivation for Transcend:

Though I was too young during the 1980s to have participated in the golden era
of video games as a programmer or designer, I am greatly inspired by the swell
of creativity that occurred during that time.

Computers and other game machines were quite limited, and this meant that you
could not fit very much content into a single game.  Thus, most games were 
distinguished by the novelty of their underlying concepts.  Having more than a
handful of members on a particular development team was overkill, and many 
games were created from start to finish by a single individual.

We saw some amazing games during that era:  just think about Tempest,
Centipede, Pac Man, and Defender.   Even if we look at those four games in 
isolation, we see four dramatically different creations in almost all respects.
From concept to gameplay to graphics, Tempest and Pac Man are about as 
different from each other as two video games can get.

Looking at the popular games of today (August of 2005), we see a handful of
narrowly-defined genres.  Games today are mostly distinguished by their 
settings and content.  For example, _God of War_ was just like _Devil May Cry_,
but it was set in ancient Greece instead of in a Gothic castle.

Imagine a new board game that is just like Monopoly, but set in Miami instead 
of Atlantic City.  Would that be a unique or interesting game?  In fact, 
Parker Brothers does market these locale-specific Monopoly modifications, but 
no one calls them "new" games.  So why would anyone hail _God of War_ as a 
"great new game"?    

The main reason people plunk down $50 to play _God of War_ is to see the 
graphics and experience the world that it creates.  So, they are paying for 
special effects and a trip to ancient Greece, not for a unique or interesting 
game.

But why the short list of narrow genres?  What happened to the Tempest genre?
There was never such a genre, ignoring a few Tempest knock-offs that appeared
over the years.  People were too busy inventing their own new games to worry
about building genres of nearly-identical games.

We all know what happened:  games became very expensive to produce as the 
hardware platforms became more capable and the focus moved toward content.  
When you go from a single designer/programmer to a team of hundreds, your 
budget skyrockets.  Game design became financially risky.  I do not need to 
delve deeper into the history here---the simple result of this trend is 
stifled innovation in the video game industry.

But if games are boring today, how can we again start making non-boring games?
We need to move back to single-person teams and focus on unique game ideas.

Of course, there are major limits to this kind of process, especially when you
compare it to main-stream game development:  no huge, virtual worlds;  no 
motion-capture;  no highly-detailed polygon models or texture artwork;  and 
no support for the PS3.

Still, given these limitations, we can perhaps design fun, interesting games.

Transcend was my effort to explore the development process of the golden era.
I first came up with a unique idea for a game that was unlike any of the games
I had ever played.  Then I designed and programmed that game by myself over
the course of several months.

The resulting game is playable on a computer that is pushing ten years old, yet
still pulls off graphical tricks that will make you say "wow" from time to 
time.

Transcend proves that there is plenty of interesting space left to explore in
the game design spectrum without a team of hundreds or a massive virtual 
world. 

On the other hand, just imagine what a team of hundreds could pull off with the
latest hardware if they could just get out of the five-genre rut.

In answering the following qualitative content questions, please include a full description of all pertinent content.  Remember that pertinent content can be found in any material included with the product (including bonus material, hidden software, easter eggs, cheat codes, advertisements and product placements, etc.) In all cases, the most extreme instance of any pertinent content must be specifically detailed.

(2) the context in which the specific content occurs, meaning what else is going on in the game at that time.
Please give clear, thorough, and specific descriptions of all requested content. Do not provide promotional or marketing language; this language is not relevant for rating purposes. For example:
Correct:
"There are 11 levels to play as the hero Omega battles and defeats the Evil Forces controlling him. Based on the famous comic character, the hero uses hand-to-hand combat as well as an arsenal of weaponry and superpowers to complete each mission in the game. This game features several different styles of game play, including:  
Action- revolves around the hero fighting enemies in fierce battles.  
Puzzle Solving- requires the player to figure out mission puzzles, such as unlocking hidden doors and getting into a security system allowing the hero safe passage.  
Stealth- allows the player to avoid involving the hero in outright confrontation, and instead use a variety of stealth moves to knock out and evade enemy soldiers.  Some missions will be impossible to complete without using the stealth skills."Incorrect:
"Product is a thrilling first-person shooter experience that has to be SEEN to be believed. Nowhere else will you find such AWESOME gameplay and tension!"

{\bf Game:} Transcend

{\bf Author:} Jason Rohrer

\setcounter{section}{3}
\section{OVERALL GAME CONTEXT}

Transcend is an abstract shooting game with geometric, morphing graphics.
There are three levels.  In each level, the player guides a ship-like glyph 
around a grid.  Minor anti-glyphs (enemy objects) attack the player's glyph 
by shooting at it.  When the player's glyph is hit by an enemy projectile, it 
is knocked toward the center of the grid.

The player can increase the power of her projectiles by gathering elements
from around the grid and bringing them to the center.  The elements form
a visual collage, and each element also represents a section of music.
Thus, while powering up her projectiles, the player is also arranging a piece
of music that plays in the background.  Anti-glyphs also attack the player's 
collage by shooting at it, and these attacks push elements away from the 
center.

The player can defend her glyph and collage against enemy attacks by firing projectiles at the minor enemies.
These weak enemies can be destroyed with a single shot.   

The player's goal in each level is to destroy the major anti-glyph, a large
enemy object that circles around the outskirts of the grid.  When the player
approaches the major anti-glyph, the anti-glyph attacks the player's glyph
with powerful projectiles.  The player must shoot the major anti-glyph many
times in succession to destroy it.  After the major anti-glyph has been
destroyed, a portal opens that allows the player to move on to the next level.


\section{VIOLENCE}

\subsection{Violence Depicted}

{\bf Describe specific instances of the above forms of violence, and the context in which they occur:}
\\
\\
The player shoots projectiles at abstract enemy entities.  These entities are
controlled by the computer and behave autonomously, so they are best described 
as ``robots'' and not as ``objects.''  However, they do not represent robots 
specifically, but instead represent an abstract enemy force.  When enemy 
entities are destroyed, they morph into geometrical explosion displays and 
then fade away.
\\
\\
{\bf To what extent can the player control the depictions of violence?}
\\
\\
The player hits the SPACE bar to fire each projectile and aims projectiles
using the ARROW keys.  Thus, the player completely controls each act of 
violence.  However, the depiction of the destruction (in other words, the
explosion graphics that are displayed in each case) are controlled by the
computer.
\\
\\
{\bf Describe how violent acts are rewarded in the game, i.e., is the player 
  rewarded for successfully completing, avoiding, or preventing acts of 
  violence, aggression, injury, or death?  Include specific instances of such 
  rewards, and the context in which they occur:}
\\
\\
The player is rewarded indirectly for destroying minor anti-glyphs because the
player gets a break from enemy attacks until the next wave of anti-glyphs 
appears.  In other words, it is difficult to build an element collage while
anti-glyphs are attacking, so the player will benefit from destroying these minor enemies.

The player is rewarded directly for destroying the major anti-glyph by gaining
access to the next level.


\subsection{Violent Sound Effects}

{\bf Describe specific instances of these sound effects, and the context in which they occur:}
\\
\\
Each projectile fired is accompanied by a musical note.
Each enemy explosion is also accompanied by a musical sound.
These sound effects are abstract and do not directly represent the violent acts that they accompany.

Hi Jason,

 

I apologize; I sent the email requesting information for the compilation to

disregard the dates items are due - just send me your information at your
earliest convenience.  Again, please accept my apologies for the mix-up.

Hi Jason,

 

We are excited to have you be on board with this Independent Games product.
We're now at the point in development where we need some information from
you in order to best feature you, your company or group, and Transcend.
This email will outline the various items we will need for you to send to
us, along with the due dates for this information.  The good news is that
most (if not all) of the information you'll be providing to us is already
created, so this process should only take about 30 minutes.  

 


Description

Due Date


6 screen shots from the game you'll have on the product.  These screen shots
are for the general interface of the game to entice users to play your game.
A screen shot of your game may also be used on the product box, on sell
sheets, or the Moondance Games website.  

8/12/05


A completed ESRB sheet.  I have attached the form that needs to be filled
out; please complete only sections 4 through 11.   

8/12/05


Final credits list.  

8/12/05


Minimum system requirements.  We will be performing QA and running the
compilation through a config lab, however it would be helpful to have
information about your particular game.  If you're unsure of the
requirements, an approximation will suffice.  

8/12/05


Company/group description.  Please provide a one paragraph description of
your company or group.  If you would like to have more information on your
company or group in the CD, you will have an opportunity to do so through
the "Extras" section. 

8/12/05


Game description.  Please provide a one paragraph description of your game.
If you would like to have more information on your game in the CD, you will
have an opportunity to do so through the "Extras" section. 

8/12/05


Brief feature list.  Please supply 4 to 5 bullet points on what makes your
game fun and unique.  

8/12/05


Genre classification.  Please let us know what genre (action, puzzle, etc.)
your game falls in to.

8/12/05


Acceptable Name Abbreviation:  In some areas of the interface we may need to
shorten the name that appears for games with long names.  If the title of
your game is over 25 characters long, please let us know how you would like
the name abbreviated. 

8/12/05


Installer information: If you game already has an installer please let us
know if there is anything special the installer does. For example, are any
registry keys created by installer? Are any files installed in locations
other than the main installation folder?  Is there anything else unusual?

8/12/05


Instructions for your game.  Please send us the instructions for users to
play your game if you haven't already.  The preferred formats are txt and
html.  

8/19/05


Email address for support purposes.

8/19/05


Optional: Concept art.  If you have concept art that you would like to show
off, please send it to us.  

8/12/05


Optional: "Extras."  Each game and developer will have an area associated
with them for extras you wish to share.  For example, you may wish to
include a link to your blog, or to an essay, or a movie file.   Or perhaps
you would like to explain why you decided to make your particular game, what
makes your game unique, or anything in particular you hoped to accomplish in
making it. 

8/19/05

 

 Please note that we may edit your submissions for readability purposes.  

 

We ask that you keep the due dates in mind, as we would like to get this
product to retailers as soon as feasibly possible.  If you have any
questions, please contact either Brian Kingsley (
 bkingsley@moondancegames.com,
763-234-1116) or myself.

Transcend:  a new video game by Jason Rohrer








a video game by Jason Rohrer











IGF 2004


The following downloads have been submitted to IGF (the most recent are listed first).  Note that the alternate downloads are available in case the SourceForge mirror system is buggy (some mirrors are slow to update).  Please try the SourceForge mirrors first.




Note:

The Transcend window defaults to being rather small at startup (300x300) to accommodate slower systems.  Please resize the window before playing according to your monitor size and system speed (if you have a reasonable 3D card, window size will not affect frame rate, so bigger windows are generally better).




First Update

Version 0.2 released on October 15, 2004.  This version includes three levels. (change log)




Important Note 1: The keyboard layout has changed slightly in 0.2.  Most important is the grab/drop key, which is now D (instead of G).  See the included how_to_play.txt for more information.




Cheat for judges: Version 0.2 includes a cheat (for judges only) that allows you to skip levels.  Press the 8 key at any time to move instantly to the next level.  This cheat is provided so that you can explore the design of advanced Transcend levels without spending too much time beating difficult enemies.





MacOS X [alternate] -- 10.2 and later.



Windows 95/98/2000/XP [alternate] -- Includes the GLUT library.

Transcend:  a new video game by Jason Rohrer








a video game by Jason Rohrer










Transcend can best be described as retro-style, abstract, 2D shooter.  The graphics are geometrical, and the pace is sometimes frenzied.


  

Two features set Transcend apart from other games.  First, its dynamic graphical engine, which can smoothly morph from one complex shape to another in realtime, produces striking displays.  Combining these dynamic shapes with subtle randomizations ensures that each new play through a Transcend level is visually different from the last.  The second novel feature is Transcend's musical power-up system.  As you play through a level, you are simultaneously assembling an abstract visual collage and arranging a unique piece of music.  Transcend merges video games with pure art---it can be viewed either as a game or as a multimedia sculpture.



Though I first read it after developing Transcend, the Scratchware Manifesto captures the spirit that motivated me to develop a game.   



Requirements


Required:

    

  • Stereo headphones or speakers
    • 

  • OpenGL
    • 

  • Keyboard
    • 



Recommended:

    

  • 3D card that can render OpenGL
    • 

  • 400 MHz or faster processor
    • 



Notes:

Development and testing took place on a 250 MHz PPC computer without a 3D accelerator card (in other words, using software OpenGL rendering).  
Transcend is actually playable on a meager system like this, though it runs a lot smoother on a faster computer with a 3D card.



The Transcend window defaults to being rather small at startup (300x300) to accommodate slower systems.  Please resize the window before playing according to your monitor size and system speed (if you have a reasonable 3D card, window size will not affect frame rate, so bigger windows are generally better).

Development


Development is managed through the SourceForge Project Page.  On that page, you can submit bug reports and feature requests.  You can also browse the source code in CVS or checkout the latest source to compile a bleeding-edge version for yourself.



I have posted some rough instructions about how to edit Transcend levels.  More information about this topic will be added in the future.

transcend-0.3+dfsg2.orig/Transcend/doc/html/roughEditInstructions.txt0000640000175000017500000001406110130740707024500 0ustar  pabspabsAll graphics in Transcend are generated by "object spaces" that map a [0, 1] parameter into a 2d object (an object made up of colored triangles and a line border).  Every parameter in the range [0,1] gives a slightly different object, and by changing the parameter slowly over time, the object will smoothly morph from one form to another.  

To relate this to something you have probably seen before:  Think about a color gradient, where 0 is red and 1 is green, and the color changes smoothly from red to green as you move from 0 to 1.  You can make the color bar more complicated by sticking a black control point at 0.25 and purple control point at 0.75.  Now the bar goes smoothly from red to black to purple to green.  You can add extra color control points and make a very complicated color bar.

Now imagine a spectrum of object shapes instead of colors.  Instead of having color control points, you have object control points that specify what the object should look like at a given point.  Thus, at 0 you could have a star shape, while at 1 you could have a square.  The spectrum would then blend smoothly from a star to a square, with 0.5 being an object that still looks a bit like a star but also looks a bit like a square.  If you stick a triangle shape control point in at 0.25, the spectrum will blend from a star to a triangle and then to a square. 

Making a Transcend level basically involves specifying a bunch of different object spaces (one for each object:  a space for enemies, another space for their bullets, a space for your ship, etc.).  In turn, specifying a space involves setting as many control points as you want in that space.  The minimum, of course, is 2 points per space (one at 0 and one at 1).  Each point has:

--An anchor in the range [0,1]
--A set of triangle vertices (each with X,Y and R,G,B,A)
--A set of border vertices (each with X,Y and R,G,B,A)
--A border width parameter
--A number of rotated copies (to create a "flower" type effect, with multiple copies of the shape rotated around a center)
--A scale factor for rotated copies (to create a spiral type effect, with each additional copy/"petal" getting smaller (or larger) than the last)
--A scale factor for the angle between copies.  With a factor of 1, the copies are spaced evenly around the circle.  Larger values spread the copies out more, and smaller values squeeze the copies closer together
--A rotation rate for the object (how fast it spins)


Here is a sample control point:

This point is anchored at parameter 0.  It has 6 triangle points (in other words, two triangles) and 4 border points.  Each vertex (either triangle or border) has an X,Y coordinate followed by an RGBA color.  Consider the first triangle vertex:

1.000000 0.000000
1.000000 0.000000 0.000000 1.000000

This vertex is at the point (1,0) and it has a color that is solid red.

At the end of the control point are 5 values (each on a separate line) that represent border width and the other parameters that apply to the entire object.  For example, this object has a border that is 2 pixels wide, there are no rotated copies (single object, does not look like a "flower"), and it doesn't rotate (rotation rate of 0).

This control point comes from the file 

levels/001/enemyBulletClose

and there is one other control point in that file.  That space determines how the enemy bullets look at close range, and there is a separate space for the far-range bullet shape.  Each enemy has a close range and a far range parameter, and the bullets blend smoothly from close shape to far shape as they move away from the firing enemy.  Thus, you can understand why every enemy has bullets that look slightly different.

One thing to keep in mind is a trick to ensure smooth object blending:

--All points in a given space should have the same number of triangle and border points, and the points on one control point should "correspond" with the same points, in order on the other control points.  If the number of triangles changes across an object spectrum, triangles will "pop in" or "pop out" during a blend, thus ruining the smooth effect.  Also, if you don't keep track of corresponding vertices across control points, you can get some "ugly" effects.  For example, if a left-most vertex from one control point is used as a right-most vertex in another control point, the object will "twist" across itself during a blend. 

As text objects, these control points are pretty scary:  it takes *forever* to edit a Transcend level by hand.

I have created an editor program for control points, but it is a little clunky.  It only can handle single control points and does not deal with entire spaces.  To use it, you must copy a control point into a separate, temp text file and open it with the editor.  After editing, you can save the control point and then copy the new text for that point back into your object space file.

Since the editor only deals with single points and not object spaces, you *should not* include the parameter anchor (the [0,1] value) in the temp text file.  Just the control point with no anchor (from above, you would start your copy-past selection at the "6".

The keyboard controls for the editor are described in the source:

Transcend/editors/doc/controls.txt

The best way to get the editor is to build it yourself from the source distribution.  Have you tried compiling the source yet?  After you have built the game, change to the editors directory and type:

make

to build the editor.  Then run the editor from the command line, passing in the name of the temp text file.

I wanted to keep the controls simple, so I avoided a "strafe" feature... but maybe the fixed length umbilical key would be interesting.  It would give some physical presence to the umbilical and make it more central to the gameplay (right now, it is basically just a status display).


From Adaska too:

How to deal with counter-intuitive weak bullets that are visible but do nothing
to minor antiglyphs?

Maybe the bullet spectrum should have a particularly weak shape at 0 and
then a much stronger shape at 0.01 so that the first collage piece causes
a dramatic change.

Also, the weakest bullet shape could cause minor antis to divide into 2.
Maybe fun, but might be annoying.



October 8, 2004

From David Greene:

> as a bullet... I think I like the "early fade-out" idea best, but it

Well, I could just cause the bullet to start fading whenever it is within X pixels of an enemy.  That would be pretty easy.

> Maybe the bullet should *bounce off* the anti-glyph instead...

> Larger bullets -- increase the affected area by a factor of two or so.

> right.

Sort of like a boomerang, no?

While thinking about this, I thought about a double-bullet bonus idea:  
When you shoot, one bullet goes straight out, as usual, but another bullet 
travels down the umbilical, all the way back to the center.  Thus, if you are 
clever with your ship position, you can kill minor antis that are attacking 
your collage while you are out chasing the major antiglyph.  


October 13, 2004

Found potential cause of absent enemy bug on win32:
When locking down maximum timejump per frame, we sometimes seen an attempted
timejump of around 4 billion ms.  This, of course, would cause the enemies
to jump way passed the glyph and off the grid completely.  It would take
them forever to return.  Of course, the "in grid" constraints for the glyph
and major anti keep those in the picture even during a huge timejump.

Need to figure out why Time class is returning such a huge value.

In any event, limiting timejumps is an temporary fix.


Started working on a PortalManager class for the exit portals.


October 14, 2004

Got portal stuff working.
Checked for memory leaks.

Found bug in Time.h that botches MS calculation when the time delta goes
beyond the next second (for example, taking diff between 1s001ms and 0s999ms
would return a bogus value because of a sign error).

This may be the cause of our "huge position jump" on win32.

Since enemies would jump also during a large time jump, this fix handles
the "no minor enemies" bug.


Still seeing huge timejump bug in win32.  Need to investigate more.
Maybe need to put some special code in Time.h to detect the exact source of
the problem.

Found this bug.  ANSI time() seconds and win32 GetLocalTime seconds are
not calibrated (ANSI seconds can roll over after GetLocalTime seconds roll
over) resulting in bad time delta calculations.

Replaced this code with ANSI mktime code.  It works now (after all these
years of using incorrect win32 timing code... yikes!)


Ready to start working on next level.

  of level 001)



October 19, 2004

Several suggestions by David Greene (smooth back off, boss progress, bullet
collision indicators).


October 21, 2004

Excellent suggestion.  This would add the needed "progress" display without covering up any part of the boss.

August 21, 2005

Working on fixes for Moondance compilation release.


August 22, 2005

Worked on more fixes.

Currently working on boss damage indicator.

Got code to compile, but it behaves oddly, then segfaults.



To do for next release:
X-Fix zoom behavior when strafing.
X-Fix minor anti-glyph pop-in upon creation... they should fade in instead.
X-Make minor anti "back off" behavior more smooth.
X-Change to allow pick-ups while a piece is being jarred... maybe force a drop
  if the jar force is increasing?
X-Make bullets fade out.
X-Make pick-up radius wider to make game easier.
X-Fix jerky pick-up and drop somehow...
X-Add some kind of progress indicator to each boss.
X-Add extra shapes to each level that are "spit out" whenever a bullet
  is in contact with a target (to indicate that the target is being hit).
X-Spit out mini-explosions can change shape depending on the health of the 
  boss.

\section{Short description}
Transcend is an abstract, 2D shooter.  The morphing graphics engine creates an alluring visual display.  Using musical power-ups, players simultaneously construct churning visual collages, arrange unique pieces of music, and strengthen their projectiles.  Transcend blurs the line between games and art---is it a video game or a multimedia sculpture?

How to play Transcend



Preparation:

Stereo headphones or speakers with good stereo separation are highly
recommended.  The music generated by Transcend is in stereo, and how
you interact with Transcend affects stereo positioning in the music.
Transcend is playable on a monophonic sound system, but many subtle 
sound features will be missed.



Basic Keyboard Controls:

Arrow keys:  direct your glyph around the plane

Space bar:   fire projectiles

D key:       pick up or drop an Element   

P key:       pause the game

Q key:       quit


Advanced Keyboard Controls:

S key:       slide your glyph to the left   

F key:       slide your glyph to the right





Quick instructions:

To win a level, you must destroy the major anti-glyph.  Your glyph starts out
very weak---its initial projectiles are powerless (they cannot even destroy
minor anti-glyphs).  Build the strength of your projectiles by gathering 
Elements from the plane and dropping them near the center of the grid in a 
collage.  Minor anti-glyphs will try to break apart your collage---destroy
them with projectiles (you need at least one Element in your collage to
have projectiles that are powerful enough to destroy minor anti-glyphs).
After you destroy the major anti-glyph, a portal will appear.  Pass through
this portal to move on to the next level.  

A more detailed description is given below.



Game Components:

A level in Transcend contains the following components:

Your glyph  --  always at the center of the screen.  This is the component
                that you control (i.e., "you" in traditional game-speak).

The plane   --  marked by a grid.  Your glyph can travel anywhere on this grid.

Umbilical   --  A colored line that connects your glyph to the center of the
                grid.  This line's color and width change according to 
                your current projectile strength and attributes.

Elements    --  Stationary objects that start out strewn along the border
                of the grid.  Your glyph can pick these up and move them
                around.  Elements can be dropped at the center of the
                grid to form a power-up and music collage (see below).

Music cursor  --  A red, yellow, and green line that traverses your Element
                  collage.  This line moves to show the current music position
                  in time.  The vertical extent of the cursor represents the
                  stereo space (red is right, green is left, and 
                  yellow is center).  

Minor anti-glyphs  -- the enemy.  These mobile components pursue your glyph
                      and the Elements in your power-up collage.

Major anti-glyph   -- A large enemy that travels in a circular path
                      around the grid.  This enemy is your primary target:
                      when you destroy the major anti-glyph, you can move on
                      to the next level.  

Portal             -- Appears after you destroy the major anti-glyph.
                      While the portal is visible, minor anti-glyphs will stop
                      attacking.  You can explore the various Elements and
                      musical possibilities without being bothered by enemies.
                      Pass through the portal to move on to the next level.



Enemy attacks:

When you are hit with an enemy projectile, your glyph drops any Element that 
it is carrying and is propelled back toward the center of the grid.  When an 
Element is hit by an enemy projectile, it is propelled away from the center
of the grid.  Once you have started building a collage of Elements, the
minor anti-glyphs will try to knock Elements out and disrupt your collage.  



Power-up and music collage:

Elements that are dropped near the center of the grid (where your umbilical
ends) form a collage.  Elements that are dropped near the collage
also become part of the collage (thus, a collage can extend far away from
the grid center as long as some Element in the collage is near the center).

Each Element represents a projectile power-up.  The Elements in your collage
are combined to determine the strength and form of your glyph's projectile.   

After your collage contains at least one Element, your projectiles will be
strong enough to destroy any minor anti-glyph in one shot.  However,
the major anti-glyph is much more durable, and a relatively large collage will
be needed to make your projectiles strong enough to destroy it easily.

If your collage grows to be asymmetrical and/or off-center, your projectiles
will become weaker (they will appear transparent and your umbilical will become
thinner). 

In addition to a projectile power-up, each Element represents a section of 
music.  A cursor traverses your collage and plays the music associated with 
the Elements that you have assembled.  Thus, a chain of elements that extends
perpendicular to the cursor will be played sequentially in time.  A chain
that extends parallel to the cursor will be played simultaneously in time
but spaced out in stereo.

Remember the glory days of arcade gaming?  Solo creators, abstract graphics (exactly what is the Tempest "claw" supposed to look like?), and innovative game-play.  Hardware was too primitive to do anything flashy, so designers had to innovate deeply in order to make engaging games.  Inspired by this heritage, I recently coded-up a novel 2D shooter called Transcend.  The graphics stretch the limit of what is possible with a 2D filled vector engine, and the game-play is unique (for example, to power-up your projectiles, you must construct a music collage).  Along with trying to make a playable game, I was also thinking about Transcend as a work visual and auditory art---the result can be viewed as a kind of interactive sculpture.
