Hello guys, I was playing with my ArrowHead project and I decided to test some functions thinking in a bullet hell game that I want to create in some far, far away future. The bullet control part worked well until 100-200 bullets in the screen, after this the FPS went under of 60fps. But this topic is about a script that I made to control the bullets’ “existence”.
For example, I have a object that shoot 50 bullets every second, each bullet have 2 seconds of life and this object have 30 seconds of life. So why should I create 1500 bullets when I can create 100 bullets and recycle them. So I did this script and I am looking for feedback, it is working pretty well in my platform game but my game is pretty simple. Maybe I’ll upload it to wiki if it is good ( I want to post something there 
)

How to use
private var pinBuffer : ObjectBuffer; //Just create a gameObject, put the ObjectBuffer component and fill its variables
...
//Creating a pin, whoever it designed to destroy this object must have access to its buffer
var pin : GameObject = pinBuffer.createObject( Vector3(4,4,0), Quaternion.identity );
...
// Destroying the pin
pinBuffer.destroyObject(pin);
Thanks for the attention
