Have b2DebugDraw and b2ContactListener been replaced in liquidfun.js?
I am trying to replace my current Box2D library (box2dweb.js) with the Google LiquidFun library .
The main difference seems to be that they put all b2 # ClassName # classes in the global scope, rather than keeping them modular (in a namespace Box2D.*
like box2dweb).
BUT also it seems that they missed a few b2 # ClassName # , two of which I used from the Box2dWeb.js version:
- b2DebugDraw and
- b2ContactListener
Are these deprecated / not fully implemented / forgotten?

Just define the listener as a function object, for example:
var listener = {
BeginContactBody: function(contact) {
console.log(contact.GetFixtureA());
},
EndContactBody: function(contact) {
console.log(contact.GetFixtureA());
},
PostSolve: function(contact, impulse) {
},
PreSolve: function(contact, oldManifold) {
}
}
world.SetContactListener(listener);
looking at https://github.com/google/liquidfun/blob/master/liquidfun/Box2D/lfjs/jsBindings/Dynamics/b2World.js helped me solve this problem, so if you run into other C ++ translation issues -> javascript is a good starting point.
