How to create chipmunk debug layer with Cocos2d-JS v3?

Question

How to create chipmunk debug layer with Cocos2d-JS v3? I could not find an example of how to do it.

Answer 1

Assuming you have added "chipmunk" to "modules"in your projects project.json, simply place the following within the ctor or init method of the Layer that has the Chipmunk space defined in it:

//Add the Chipmunk Physics space
var space = new cp.Space();
space.gravity = cp.v(0, -10);

//Add the Debug Layer:
var debugNode = new cc.PhysicsDebugNode(space);
debugNode.visible = true;
this.addChild(debugNode);

You could also add the following to set up a "floor" and a sprite to bounce on it:

//add a floor:
var floor = new cp.SegmentShape(this.space.staticBody, cp.v(-1000, 10), cp.v(1000, 0), 10);
floor.setElasticity(1);
floor.setFriction(0);
space.addStaticShape(floor);

//add a square to bounce
var myBody = new cp.Body(Infinity, cp.momentForBox(Infinity, 10, 50));
myBody.p = cc.p(derecha - 10, arriba / 2);
space.addBody(myBody);

var myShape = new cp.BoxShape(myBody, 10, 50);
myShape.setElasticity(1);
myShape.setFriction(0);
space.addShape(myShape);
