访问box2d实体

Question

Since now, I've been accessing box2d bodies (to change or to get their values) with this for loop copied from the web:

for (var b = world.GetBodyList(); b != null; b = b.GetNext())

works fine but... Is there any other faster way to do so? Can't I just store a reference to the bodies in an array so then have always access to it?

Thanks!

I don't know which version of Box2DJs you're using but you can do something like this:

var myBodies = [];
var myBox = new b2BoxDef(); // or whatever the name of your body creation function is
myBodies.push(myBox);
console.log(myBodies[0]); // reference to your Box2D object
