Return a map of Bodies from an array #49

I am making a sidescrolling game, and I am rendering multiple enemies in random positions. I am working with the onCollide function so I can easily implement player/enemy collision without messing with pixels and all that jazz. The problem is that when I map an array of random points and for each index, return one custom enemy object, I can't change the reference to the body(The "this.body = b" prop) on each index. This results in each body rendering at the same point and collisions not being logged.
It has to be a body in order to calculate the collisons. I am considering moving to p2 physics for their bodies and keeping sprites and other parts of this library unless I find an efficient solution for this. Thanks in advance
