GetComponent on PickUp

Unity Engine
1

Hi!
I want to call my GameStatus Script and call a function as soon as the character collides with the “point” sphere.
I’m getting this error…

The Pickup script is attached to a simple sphere (Point) with “is Trigger” activated.

Pickup script

function OnTriggerEnter (col : Collider){
		if(col.name == "First Person Controller"){
		var status : GameStatus = col.GetComponent(GameStatus);
		status.AddPoint();
		
	}
	
}

GameStatus script

var points : int;

function AddPoint(){
	points += 10;
	print(points);
}

Let’s add two lines.

function OnTriggerEnter (col : Collider){
	if(col.name == "First Person Controller"){
		var status : GameStatus;
		status = col.gameObject.GetComponent(GameStatus);
		status.AddPoint();
	}
}

What happens ?

This may sound too basic but are you sure gamestatus script is on your “first person controller” object and not somewhere else?

You’re right Speed. I actually wanted to make a script which stores some values and is unique.
I came up with this… I made an empty game object(PlayerPoint) first and attached the GameStatus script. Then I’m calling the functions right of this object like this…

function OnTriggerEnter (col : Collider){
		if(col.name == "First Person Controller"){
		var go : GameObject = GameObject.Find("PlayerPoint");
		 go.GetComponent(GameStatus).AddPoint();		
	}
	
}

This works fine.

Now i thought I can do it on the iPhone version as well. So I build the same stuff. But I’m getting this

GetComponent returns a Component.
AddPoint is part of a GameStatus.
GameStatus is a Component.
Component is not a GameStatus.
Component does not have AddPoint.

You need to tell Unity that the Component you just got is a GameStatus. You can do this either by explicitly casting:

(GameStatus)(go.GetComponent(GameStatus)).AddPoint();

Or by implicitly casting by placing it in a variable:

var status : GameStatus = go.GetComponent(GameStatus);
status.AddPoint();

It has to do with inheritance, and Base classes not knowing what their possible Subclasses are.

I appreciate all your quick responses.

Problem solved.
