loop through scripts attached to objects in an array?

Questions & Answers

Hey everyone. I’m very new to all of this, so please forgive me for what is probably a very noobish question.

I’m spawning a prefab that includes children objects. These children objects (tagged “subUnit” have a script on them that returns a boolean value based on if they have collided with anything. I am trying to create an array of these (identical) scripts so that I can run through them and see if any of these objects have collided.

I am still learning how to reference other objects and their components so I know I am doing something wrong with the way I’m trying to access this stuff. Currently I get the error “‘GetComponent’ is not a member of ‘UnityEngine.GameObject’”. I would appreciate any help!

#pragma strict

var activePce : GameObject[];
var isQuitting : boolean = false;

// spawn initial active piece

function Start ()
{
	var clone : GameObject;
	
	clone = Instantiate(activePce[(Random.Range(0, activePce.Length-1))], transform.position, transform.rotation);
	clone.name = "Active"
}

//find the activeUnits and check each for collision

function Update ()
{
	var dest : boolean = false;
	var unitList : GameObject[];
	var collisionList : Component[];
	
	unitList = GameObject.FindGameObjectsWithTag("subUnit");
	collisionList = unitList.GetComponent(collisionScript);
	
	for (var coll : collisionScript in collisionList)
	{
		if (coll.hit)
		{
			dest = true;
		}
	}
}

You could try this instead:

function Update()
    {
        var dest : boolean = false;
        var unitList : GameObject[];
        var collisionList : Component[];

        unitList = GameObject.FindGameObjectsWithTag("subUnit");

        for (var obj : GameObject in unitList)
        {
           var cs:collisionScript = obj.GetComponent(collisionScript);
           
           if(cs)
           {
               if (cs.hit)
               {
                    dest = true;
               }
           }
        }
    }

What I’ve done here is I’ve iterated through the list of GameObjects we received from the GameObject.FindGameObjectsWithTag(“subUnit”). Then, I accessed the component “collisionScript” of each individual object.
