[JavaScript] How do you reference another object in a script?

Questions & Answers
1

We need to reference a component from another object, that isn’t parented, through a script in JavaScript.
We are very new to coding in Unity and are not quite getting it…

How exactly do we use GetComponent on a separate object?
(Please explain how to use Accessing Other Objects
and
GameObject.GetComponent)

We are trying to access the ‘Sphere’ objects Mesh Renderer and enable/disable it using a script that isn’t a component on it. While also accessing the ‘EthanBody’ Skinned Mesh Renderer component and being able to do the same thing.

Also it would be nice to know how to access an integer value from Morph script so if it becomes active it will run Morph1.

The code is just us goofing around a little trying new things, it doesn’t actually work right now (Obviously)

Morph:

#pragma strict
private var onoff: boolean = true;
var Body;
public int Invis;

//FUNCTION START
function Start () {
Body = GameObject.Find("ThirdPersonController/EthanBody");
print(Body);

}


//FUNCTION UPDATE
function Update () {




//GET KEY "G"
if(Input.GetKeyDown('g')){
	onoff = !onoff;
	
	if (onoff){
	GetComponent(MeshRenderer).enabled = false;
	Invis = true;
	} else {
	GetComponent(MeshRenderer).enabled = true;
	Invis = false;
	}

};
}

//Morph1 I.E. Different Script

#pragma strict
public var Morph : GameObject;
private var onoff: boolean = true;

//FUNCTION START
function Start () {

}


//FUNCTION UPDATE
function Update () {

//GET KEY "G"
if(Morph.gameObject.GetComponent(Morph).Invis == true){
	onoff = !onoff;
	
	if (onoff){
	GetComponent(SkinnedMeshRenderer).enabled = true;
	} else {
	GetComponent(SkinnedMeshRenderer).enabled = false;
	}

};

One method that I have seen widely used in my search queries is the following:

1.)Make a public variable in your script that wishes to use the Sphere gameobject.

2.)In the inspector, you can assign the Sphere gameobject to this variable by dragging it into the slot on the script while it is open in the inspector.

3.)You can then use the GetComponent method on your variable to get the Mesh Renderer and do whatever you please with it.

This is just one way to access a Game object from a remote script. For more information on accessing other Game objects I recommend you check out the following documentation: http://docs.unity3d.com/412/Documentation/ScriptReference/index.Accessing_Other_Game_Objects.html
