What variable get set to zero? PlayerCCC? If so, are there other places in the script that manipulate PlayerCCC? Where is PlayerCCC defined?

Sorry, should have been more clear. Yes, it's PlayerCCC that's being set to 0. It's a local variable that I declared at the start of the script. No other function calls or changes PlayerCCC.

I can see nothing in here which should set your variable back to 0. Where are you declaring PlayerCCC? $$anonymous$$y best guess is that at some point during execution of your code it's rerunning your variable definition, resetting it to 0.

Hmmm. I can't see anything, here's the complete function

pragma strict

//////////////////////////////////////////////////////////////// //////////////////VARIABLE CREATION///////////////////////////// ////////////////////////////////////////////////////////////////

//Variable for random colour selection var RandomColour : float;

var PlayerCCC : int;

//////////////////////////////////////////////////////////////// //////////////////GA$$anonymous$$E START//////////////////////////////////// ////////////////////////////////////////////////////////////////

function Start () {

GlobalVariables.ColourArray[0] = Color.red; GlobalVariables.ColourArray[1] = Color.yellow; GlobalVariables.ColourArray[2] = Color.blue; GlobalVariables.ColourArray[3] = Color.green;

renderer.material.SetColor("_Color",GlobalVariables.ColourArray[Random.Range(0,GlobalVariables.ColourArray.Length)]); }

//////////////////////////////////////////////////////////////// //////////////////GA$$anonymous$$E UPDATE/////////////////////////////////// ////////////////////////////////////////////////////////////////

function Update () {

}

function On$$anonymous$$ouseDown(){ if(PlayerCCC < GlobalVariables.ColourChangeSel.Length){ Debug.Log("PLAYERCCC = " + PlayerCCC + " < CCS.Length = " + GlobalVariables.ColourChangeSel.Length); if(GlobalVariables.ColourChangeSel[PlayerCCC] != null){ gameObject.renderer.material.SetColor("_Color", GlobalVariables.ColourChangeSel[PlayerCCC].renderer.material.color); Destroy(GlobalVariables.ColourChangeSel[PlayerCCC]); PlayerCCC += 1; Debug.Log("NOT NULL. PLAYER CCC = " + PlayerCCC); } else{ PlayerCCC += 1; Debug.Log("NULL.PLAYER CCC = " + PlayerCCC); } } }`

I don't see anything obviously wrong. If you comment out the destroy does it work? I noticed you do not initialize the variable. Is it initialized in the inspector or does some other script initialize it? Are you seeing errors in the Console? If you had an access error, PlayerCCC would not be incremented.
