var texture1 : Texture2D;
var texture2 : Texture2D;
private var pressed : boolean;
private var close : boolean;

function Update(){
	if (pressed){
		GetComponent.<Renderer>().material.mainTexture = texture1;
	}
	else{
		GetComponent.<Renderer>().material.mainTexture = texture2;
	}

if(Input.GetKeyDown("e") && enter){
pressed = !pressed;
}
}
  
function OnTriggerEnter (other : Collider){
if (other.gameObject.tag == "Player") {
close = true;
}
}
