GetComponent question for Error BCE0019

Unity Engine
,

I have now read all of the threads on how to use GetComponent for Unity iPhone. I must be either tired or thick: I’m not grokking it.

Imagine I have a game object called “GlobalVars”. I want to change the value of var “pickups” inside a script attached to GlobalVars from a script (call it “foo.js”) on a different game object. So I have:

script foo.js:

var globNode : GameObject;

function Start (){
	globNode = GameObject.Find("GlobalVars");
	globNode.GetComponent(global).pickups += 1;
}

This gives me the error:

Assets/_Scripts/GameScripts/StarPickup.js(24,35): BCE0019: 'pickups' is not a member of 'UnityEngine.Component'.

Can someone please give me an example of how this should be (re)written? I am stuck and would sincerely appreciate someone’s help.

Thanks in advance.

You cant reference the component directly with Strong Typing as you are “talking” to a component of one type (global), while the base of the call is a component of another type (GameObject), so you need an extra step in there.

You need to create a var specifically of type global to reference the item inside it.

var globNode : GameObject; 

function Start (){ 
   globNode = GameObject.Find("GlobalVars");
   var globals : global = globNode.GetComponent(global);
   globals.pickups += 1; 
}

How would that solution apply to:

var playerNode : GameObject;

function Start() {
	playerNode =GameObject.Find("Player");
}

function Update () {
	
	if (playerNode.active) Object.SetActiveRecursively (true);
}

Thanks!

Thanks, Seon!

Worked like a charm…

Your problem here is this:-

Object.SetActiveRecursively(true);

Object isnt defined as anything. If it is the playerNode you are trying to turn on (with all of its children) then just use this.

var playerNode : GameObject;

function Start() {
	playerNode =GameObject.Find("Player");
}

function Update () {
	
	if (playerNode.active) playerNode.SetActiveRecursively(true);
}

I’m really not quite sure what you are trying to achieve with the script above.
