I'm trying to track down a bug that causes my program to crash. It may be related to how many sprite commands I'm using, or might be just the number of lines.

So - how many lines of code, approximately, does your program have?

And would you say you have a large percentage of sprite commands (CreateSprite, SetSpriteDepth, SetSpriteVisible, etc.)?

My test program crashes at around 2,128 lines of sprite commands.

I'm at 1472 and that includes all comment lines and blank lines between stuff.

I have a reasonable number of sprite commands, and I loop through quite a few sprites to check stuff (like collisions, visibility, prep for deletion) pretty much all the time.

In fact I've just written a little bit of code to draw 360 1x1 pixel sprites around my player in a circle and I update those as the player moves. No issues yet - at least on my desktop.

Does your app crash or the compiler? If it's the app what size is the bytecode file?

I'm way below your number Rich, but if you think your game is crashing for something related to sprites, why not create a simple application that loads an image and do a lot of sprite operations. Of course it doesn't replicate the complexity of your game, but if it is something related you should be able to reproduce using a big loop doing CreateSprite, etc...

Cheers

Ummm...

That's what I did. I think it's the number of commands, not the number of sprites, though.

@empty - The error message that pops up is "AGK Compiler has stopped working" so I guess it's the compiler. The .byc file is 881k and the SourceCode.agc and the .dbpro files are both left behind.


The compiler log window shows

Compiling: main.agc
Broadcasting app...(click Abort to end broadcast)
Process terminated with status -1073741819 (0 minutes, 5 seconds)

When I use these two commands



repeated for a total of 1,361 commands, no blank lines, no comments, and a simple sync loop at the end, the program runs.

If I add one more SetSpritePosition, then it crashes, but it takes two more SetSpriteDepth commands to crash it.

I've attached the project, if anybody would care to try it and report back the results.

Also, I've reported this in the new bug forum on Google

Well it's not related to number of sprites, I tried this...



...and it works perfectly.

I then did what you suggested and created a program that had each sprite created manually rather than in a loop and it failed to compile; the compiler gave the following error.

Compiling: main.agc
Process terminated with status -1073741819 (0 minutes, 13 seconds)

So it does indeed seem like there is an issue with filesize/number of lines.

I am currently at 2040 lines although that is less than it was last night. I had a crashing problem, or to be more precise, non compiling. I had to delete some (thankfully) uneeded code I had left in from the start of the project to get it to run again.
The rather unhelpful error message read along the lines "-1073741819 (0 minutes, 10 seconds)"
I just posted a query in my WIP also, but saw this thread and thought it might be along the same lines as what happened to my project.
BTW, there was no problems with the code I deleted, it was simply unneeded and not even being run anymore. It still stopped the game from compiling, if I didn't rem it out or delete it.

From my investigations last night I concluded it to be the program size, rather than anything else but I could be wrong. I do have a fair amount of sprites in my game.

I notice my error message is practically the same as yours although for some reason my comp takes 10 seconds, rather than 5 to mess up lol.

Rich..........

Is this lines of code in one file or you have also tryed to split up the code in to multiple files with an combined amount of lines from that?

I have alot of lines of code but split it in to multiple files.

Hmmmmmm....
Counted my lines of code in all files and iam only at 1556 lines.

But good to know if it happens to me

My first game came in around 800

My second game is at 1100 and counting, but it is nearly finished. (today or tomorrow)

My only unexplained crashes are when I use 6 or more sound files.
So, now I am creating my sounds in a way that I can combine them for more unique effects by playing 2 or more at the same time.

Well, I saw another post about it and I get the same results.

On the 6th LoadSound I get crashes.
If I comment any of them out, then it works.
I am not the only one, so, yes it is a bug, but obviously tied to something else.
We just haven't figured that out yet.

I have also hit the "-1073741819" compiler crash and my program has also grown (too) long with 2325 rows.

As far as I have discovered, it seems to be related to the size of the generated bytecode file. As long as the bytecode doesn't exceed around 1024000 bytes it compiles without problems.

It doesn't seem to be affected by what kind of commands used (sprites, text, loop, functions) but more with how large the generated code is.

I have my program split up into several .agc files but also tried to join the program into one single main.agc file and the compiler crash shows up in both cases.

Looks like time to optimize and shrink the code then

Seams the tgc didt expect people to write to large apps with the agk or something ?

Wath sound format do you use ?

I simply use the same as the space shooter sample to load my sound and it works for me.

function CreateMusic( )
LoadMusic ( 1, "space/track1.mp3" )

SetMusicSystemVolume ( 70 )

PlayMusic ( 1, 1 )

LoadSound ( 1, "space/Chp_Lazer3.wav" )

LoadSound ( 2, "space/Chp_Boom.wav" )
LoadSound ( 3, "space/Chp_Boom2.wav" )
LoadSound ( 4, "space/Chp_Boom3.wav" )

LoadSound ( 5, "space/Chp_Boom3.wav" )
LoadSound ( 6, "space/Chp_CheckPoint3.wav" )
LoadSound ( 7, "space/Chp_PickUp2.wav" )
LoadSound ( 8, "space/Chp_Alien.wav" )
SetSoundSystemVolume( 60 )
endfunction

Yah, it's looking like it's not the sprite commands, it's ALL commands, but each command seems to have it's own limit. For instance you can have a bazillion lines of

print(a)

with no crash, but only 103 lines of

print("a")

causes a crash. 102 lines of it, no crash.

That's good news for me, I can drop a bunch of non-sprite-related code and still get my program working again, hopefully.

I use WAVs generated by Audacity
The sounds work fine, as I can replace one with the other and they all play.
The problem is when I load the 6th one. (I don't even play it)
More than 5 and I crash.

I am starting to think that maybe the integrated sound on this laptop maybe the problem, but I don't know.
I will experiment more and test it to death, but that will have to wait until after my game is finished.
I am too close to the end now to get side tracked with anything.

Interesting
That explains the problems I was having with Angry Piglets.
It got to the point that I could not add in any more sprites without it fouling up.
I wanted to have different images for my backgrounds, but had to settle for a color adjustment of just the one.
Anyway, I was able to get daylight/evening/night effect with it though, so there is a workaround for everything.
We just have to find workarounds until the guys at TGC get to work out these few issues.
It is still early in development, so I am sure we will find more quirks, but nothing Lee, Mike, and Paul can't fix.

I hate to bump this up, but this seems to be a huge issue. Each command has its limit as you've stated. I've already hit the limits for the LoadSound() (Which also means I've hit the limit on LoadMusic() ), and LoadImage(). So I haven't worked on my project for over a week

hockeykid, I feel your pain as well. With Lee gone for a week, and nobody else at TGC looking at the bug board, we'll just have to have some patience and hope Lee looks into the problem when he gets back.

AGK Particle Sandbox is dead in the water unless this gets resolved.

My code is at 1604 lines, and is extensively sprite and image heavy. I'm not using any sounds yet, but have loaded 12 music files.

I too get either a "compiler has stopped working", or a "Game.exe has stopped working" error.

This is a very annoying issue as we can't work around it!

What about making emergency custom commands using functions, until the issue is resolved?

MYprint("test")

Function MYprint(x$)
print(x$)
endfunction

Will that also crash at a given calls to that function?

The same idea i have bin using lately
It shouldt do it as you only have the command once but is the error in how many times you use an command ??

The bug is having too many lines in your program. The limit changes somehow, according to which commands you use. I just used print("a") as an example. I don't want 104 lines of print("a") in my program.

I've tried concatinating lines, like



but that doesn't affect the bug.

I've been able to squeeze some statements, like



but I'm still hitting the limit.

LOL - I've been trying to pare down my code by re-using text and sprite objects, basically only creating twelve of each, and then moving them around and changing the image/text values. This is in an effort to reduce the number of lines in my program, so I can get it to compile.

Well, it bit me right in the butt...

I've been changing out CreateText() for SetTextString(), but it seems that using SetTextString() lowers the "command cap" limit by two lines every time you use it. So by swapping the two commands, I'm actually DECREASING the number of lines that will fit in my program!

Man, I hope they get this fixed soon!

Oddly enough after switching a few variables around I got it to work again after hitting the crash issue. Sure, it's a bit clumsy using three variables for the same global value, but for now the workaround seems to work.

This is a fairly random issue it seems.

To recap what is known about this bug...

The compiler has a limit on the number of commands it can build.

The limit is not a hard number, it varies from program to program.

The limit is affected by which commands are in the programs. From testing, it seems that CreateText() uses up one "slot" in the number of commands, but SetTextString() uses up two.

When the limit is reached, the compiler may crash, or it may build a project, but then the player crashes when the program runs. This problem is related to the command limit, as it goes away when the number of commands is reduced.

Thanks for keeping this updated.

I have been working a lot recently so have not been programming as much as I would like, but know I'm back into it I will no doubt be hitting the limit soon.

I thought I read somewhere that Lee is away, no doubt will make this top priority when he's back.

Maybe we need to #include other scripts instead of trying to put everything into one.

Have you guys tried that?

So I've been commenting out huge chunks of code in my program, so I can work on the rest of it, robbing Peter to pay Paul, so to speak, when it hits me...

That's exactly what I would do to produce a demo program! Disable a few key features, and voila!

Anyway, if it works out, I could possibly release a demo of AppGameKit Particle Sandbox this week!

Just noticed something that Impetus73 wrote about earlier!

I made an function earlier where i used this!

VR.Width = GetVirtualWidth()
VR.Height = GetVirtualHeight()

And got an silly idea to change all my getvirtualwidth-height to my shortcuts from my function.

My bytecode file dropped from 996 kb to 984 kb?

And i also got an performance boost.

So there seams to be some truth in making some kind of global value of an agk command that you use alot in your code.

Just some things i noticed today

Ps....
dosent work on all commands! as i tryed to make some commands in to an function and the bytecode file got larger instead.

I think this problem shows up when your bytecode goes over 1MB

Size: 0,97 MB (1 024 000 bytes) - OK
Size: 0,97 MB (1 024 300 bytes) - Crashes

It has happened to me with bytecode files sizes MUCH smaller than that. My example of Print("a") has a bytecode file of just 36 kilobytes in size.

It may be related to bytecode size, we just don't have the tools to fix bugs, only TGC can fix them.

Here's another conundrum, when I run the Print("a") code on my vista, it crashes at 104 lines. When I try it on an older XP system, it crashes at 115 lines, with a completely different error, "Unknown Instruction 147456376 at line 134217825.

Just hit the wall myself. Just about finished with a standalone beta for my project, was just going to add some text with what is included in my little app, what is to come and a some small instructions. No dice. Would not compile.

I'm guessing the last few CreateText calls in my (planned) instructions screen was the straw that broke the AppGameKit compilers back...

This size and number of calls to various commands bug need to be fixed ASAP.

Oh, and I am at about 1400 lines of code, including spaces and comments. Bytecode is approx. 550kb.

I think those are mainly the ones that have had the type/status/priority updated, so they have been given a "first look" at least.
