Arrays and Colliders.

Lets say i have an array of 3 GameObjects each with a collider. How can i check for collision for each individual GameObject in the array?

like

If(COLLISION ON ARRAY[0]){

    Do Something();
}

If you really want to use an array:

    import System.Linq;

    ...
    var arrayOfGameObjects : GameObject[];

    function OnTriggerEnter(other : Collider) {

        var index = arrayOfGameObjects.FindIndex(function(g) { return g == other.gameObject; });
        //Index will be -1 if no match

    }

But you could use a List:

   import System.Linq;
   import System.Collections.Generic;

    ...
    var listOfGameObjects : List.<GameObject>;

    function OnTriggerEnter(other : Collider) {

        var index = listOfGameObjects.IndexOf(other.gameObject);
        //Index will be -1 if no match

    }
