woops, missed the point they have to be convex. Anyway, box2d can’ help me doing my stuff ^^

@domi – Remember that custom shapes in Box2D have to be concave and specified in a clockwise fashion, otherwise the shape doesn’t get created properly – have you checked that’s ok?

nevermind, could’nt make it work as a ground, other shapes pass trough. or maybe it’s just me.

@domi – That’s quite interesting, I’ll have to try it out and see how it goes.

hi just wanted to let you know that we can change the max of Polygon Vertices in the file B2D.common.b2eSttings.as.

I changed it to 500 and it allowed me to build a perfect sinus wave with that code :
var pt:int = 500;//pour + de 8 changer b2settings maShapeDef.vertexCount = pt; for (var i:int = 0; i < pt; i++) b2Vec2(maShapeDef.vertices[i]).Set(i/10,Math.sin(i/10));
I don’t know about the performances, so far I’ll use this trick for a static ground shape.

all resolved, and got it working, thanks! Just had a conflicting library path

I’m not sure about the b2Shape.as or b2FilterData.as file, they’re both in the zip I’ve just downloaded from GitHub and work when I put it into a new project in Flex Builder.

I did notice that the KeyboardManager class was missing for one of the examples, so I’ll get that updated on GitHub asap.
