Properly referencing a variable from another script

Questions & Answers

Having a bad day in regards to coding - I’m having problems understanding how to properly reference variables from other scripts, here’s the script I want to reference.

#pragma strict
var lightcolour : Color[];
public var selection;
var firstchange = 60;
var changerate = 60;

function Update () 
{
	if(Time.time > changerate)
	{
		changerate = Time.time + firstchange;
		var chance = Random.Range(1,10);
	}
	
	if(chance == 1)
	{
		selection = lightcolour [Random.Range(0, lightcolour.length)]; 
		light.color = selection;
	}
}

This script works perfectly, but I want to be able to reference the variable ‘selection’ in another script and use it to change the GUI.color property of a GUI texture so that the colour of the GUI texture is the same as the light.

I’m just not entirely sure how I do this, I’ve read the documentation but I don’t understand how to reference a variable from a script.

Thanks.

So you need to relate the two scripts together:

Create a variable of type WhatEverTheScriptYouPostedIsCalled in the script attached to the texture.

 var lightScript : WhatEverTheScriptYouPostedIsCalled;

Then use the inspector to drop the light object onto the variable called lightScript.

Then use lightScript.selection in your code on the texture.
