function OnDisable () : void

Description

This function is called when the behaviour becomes disabled () or inactive.

This is also called when the object is destroyed and can be used for any cleanup code. When scripts are reloaded after compilation has finished, OnDisable will be called, followed by an OnEnable after the script has been loaded.

    function OnDisable () {
        print("script was removed");
    }
