Forums » Help » BOX2D restitution or bounciness

Hey,

Does anyone know how to make an entity bounce in box2D? It's a standard property of normal ImpactJS but in box2d this in called restitution. Or that is what is written here:

http://www.box2dflash.org/docs/2.0.2/manual#Friction_and_Restitution

But I can't seem to get it to work. Also if you look at the dom, it does not seem to be there. (box2D body properties have a m_ prefix)

does anyone know how to set it directly as a property? Or is this usually simulated with the impulse function?

thanks in advance,

Sleenee

Which version of Box2d ?

I have no idea where to find the version :), just the one Dominic has put in the physics folder on our download pages.

on createBody() something like:

var shapeDef = new b2.CircleDef();
		shapeDef.restitution = 1;
		
		...
		
		this.body.CreateShape(shapeDef);

Ok so apparently it does work but it's so hard to notice :D...i didn't notice. thanks anyway!
