Assertion failed: (3 <= count && count <= 12), function Set, file /Users/paulj/Documents/SVN/AGK108/common/Box2D/Collision/Shapes/b2PolygonShape.cpp, line 122.

This is the bug i have when i use the Shape 3 for polygon.
Please fix it or i can't publish the game.

I think is for the polygons points < 3 and it crash.

Long life to Steve!

You wanted to take the project over. Why don't you fix it?

-- Jim - When is there going to be a release?

GEKKO - You said you wanted to buy the source and improve it. So why not look at the .cpp file and suggest a fix?

hmm, if u need min. 4 points, did you try set point 3 and 4 at the same place?
this box2d is open source, maybe download newer version of it
and look if there are some changes at this position.

Is this with the automatic shape? - I'm guessing here, but if the problem is in the calculation of the 2D outline, well you could manually add polygons, and probably do a better job than the automatic outline.

I'd try adding a simple polygon instead of letting it outline - if that works, then at least it's a route around the problem.

I am the one who knocks...

Ok, lets all not start being douchebags towards each other.

Dont make me bend anyone over my knee. been a while since I had to paddle bad kids.

And its ok to report Bugs and not fix them even if you've stated you could fix the system yourself.

Look, we're all on edge waiting for AppGameKit 2 to be complete.

myself, I have so much to do with winter slamming me here in the country that my back, from shoveling snow now looks like the Hulks.

So I've been too busy to care whether or not AppGameKit 2 is done yet.

Paul and Lee are surely busy as hell, and writing a language that works on more than one system cant be easy.

So lets give them a slight break and stop goin at each other while were at it ok?

Dont force me to make you both stand in a corner.

Now I'm off to program that game thats gonna make me a millionaire.

so....Peace out!

I fight for the users!

Lol Jim you are a FOX!!!
You have the power to look in the cpp in the LIB file!!!
Come on boys!!!

All that Paul need to do is add an assert to the < 3 poligons return nothing in shape and all is ok.
The important is to not crash especially if you use TILES like in this case.

Ah, for the chronicle, i don't want V2 completed, i'm still waiting V1 is complete.

EDIT : Reading Jim answers.... Jim i don't have any source, the bug is in the AGKLib.a

Long life to Steve!

version 2.2.1 from here:
http://code.google.com/p/box2d/downloads/list
maybe ask the developers there if it was a mistake or make any sense.

maybe its possible if you overload this function with your one in tier2 (<- i think u use).



there is also a newer version for compare but i do not want install 7 zip.
Box2D_v2.3.0.7z

Quote: "AGKLib.a"


is this not compiled with the hardcodedscript batch file? I may be off from that but I do know that somethings getting compiled from Cygwin and its most likely code...lol

@GEKKO im not even close to as good of a coder as you are...but maybe dig a bit more into the compiling of the libraries as I believe all the source files I think are in there....they are just spread out in random directories.

I know the core files are found in the ide/apps/ [platform] but in order for me to compile anything I also needed to link the other files from common/include

I see the source files for box 2d in the common/collision folder so you must be able to re compile those libraries no?

This is an assertion inside Box2D that makes sure polygons have at least 3 points, I assume this is because Box2D breaks if they don't. It could also mean your shape has more than 12 but AppGameKit has limits in place that mean it should never create a shape with more than 12 points by itself. Perhaps the sprite's image has all transparent pixels meaning AppGameKit can't find a shape on the image?

Yes Paul. To avoid the problem i added 1 pixel to the image.
There is a way to fix this thing?

The polygon shape uses the opaque pixels to draw a convex hull around the image. If there are no opaque pixels then this will fail and you'll have to fall back on circle, rectangle, or a manually created polygon.

Ok Paul, so there isn't a way to add an IF to the cpp Box2D file to avoid this inconvenience?

Yes, it makes sense that it should automatically fall back to a box shape instead of producing and error message. I'll collect any small bug fixes like this into a new 108 build and when I get enough I'll do an update.
