Trying to design some object pooling

[JerryScript]

Except in extreme cases, object creation and collection is not going to be a massive performance bottleneck.

Try a simple loop test with sufficient iterations, do one test that creates new geom objects (rectangles, points, etc), and do another one that uses object pooling. I think you'll find that object creation with some of Flash's native classes can be a very big bottleneck.

One special case in the originator's game is the lasers. Generally speaking, a laser will be virtually instantaneous from origin to target. Due to this, you can use a simple pooling method that only has to loop from numberDestroyed to numberCreated, rather than having to rearrange a linked list based on destruction. For bullets and missles this won't work due to some objects being destroyed out of the creation order.
