Disable friendly fire

Object Pooler
public static Dictionary<string, List<GameObject>> pool = new Dictionary<string, List<GameObject>> ();
The Pooler contains some "bullets" to be fired.

Im activating an Object from the Pooler like this
PoolManager.pool [prefabName] .SetActive (true);
This activate a bullet

The Bullet has an
OnTriggerEnter()

The problem
Both the Player and the Enemies use the same Pool, but how do i tell the Bullet who shot it, so that Enemies dont shot eachother?

And how do i format Code on the forum?

 

Last question first: formatting code is easy if you use the "Insert" button (in the toolbar between the movie filmstrip and the floppy disk).

Next: when you activate the bullet object, you will need to also change it in some way — assign it a new Layer or Tag, or get whatever component represents "bulletness" or "which team I'm on" in your game, and tell it which it is.
