Change a variable from another script (JS)

Unity Engine
1

Hello everyone!
I am trying to change a variable which is located in another script.
Does anyone know how I can do this?
I have already checked the Script Reference and some other questions but they either use C# or I just can’t seem to be able to implement their examples.

Here is an example of two scripts and how I am trying to access a variable from SCRIPT02.js:

// >>>>>>>>>>
// SCRIPT_01.js
#pragma strict


function OnMouseDown () {

	var imported_script02 : SCRIPT02;
	imported_script02 = GetComponent("SCRIPT02");

	click_count++;
}



function Update () {

	var imported_script02 : SCRIPT02;
	imported_script02 = GetComponent("SCRIPT02");

	if ((click_count) == 10) {
		Debug.Log("mouse has been pressed 10 times");
	}
}
// <<<<<<<<<<



// >>>>>>>>>>
// SCRIPT02.js
#pragma strict

var click_count : int = 0;

// <<<<<<<<<<

Many thanks in advance for any help!

Read http://docs.unity3d.com/412/Documentation/ScriptReference/index.Accessing_Other_Components.html
imported_script02.click_count is how you access it after you find the reference.

First of all, thank you very much for your help!

I tried to access the variable now in that way, but the Console says:
“NullReferenceException: Object reference not set to an instance of an object”.

At the point I try to change the variable, the second object (which holds the second script) will disappear from the Inspector’s Script-tab of the first object.
Any ideas what could cause this problem? Maybe I misunderstood something?

EDIT:

I solved the problem now.
“var click_count : int = 0;” has to be a static variable. I only used var and public var when testing it.
Also,

var imported_script02 : SCRIPT02;
imported_script02 = GetComponent("SCRIPT02");

can be used outside of the functions so that it’s not required several times.

So, if someone has the same problem, the right way to do this is:

// >>>>>>>>>>
// SCRIPT_01.js
#pragma strict

var imported_script02 : SCRIPT02;
imported_script02 = GetComponent("SCRIPT02");

function OnMouseDown () {
    imported_script02.click_count++;
}

function Update () {
    if ((imported_script02.click_count) == 10) {
        Debug.Log("mouse has been pressed 10 times");
    }
}

// >>>>>>>>>>
// SCRIPT02.js
#pragma strict

static var click_count : int = 0;
