Change gameobject sprite with button

Question

Hi. Iam working on system, where button can change sprite render object. So i maked 2 scripts, first-

 #pragma strict
 public var sprajt: Sprite; 
 function Update() {
  GetComponent(SpriteRenderer).sprite = sprajt;

This script is in gameobject. Second-

 #pragma strict
 public var sprajtTWO : Sprite;

GetComponent searches on the gameobject the script it is mentioned on. so your script on the button has the GetComponent looks for the button to find onjectScript. that is not what you want. you should first find the gameobject who the first script is on, with GameObject.Find and after call GetComponent on it.

 GameObject.Find("yourObjectsNameWithTheFirstScriptOn").GetComponent.<objectScript>().sprajt = sprajtTwo;

The code is untested.
