Já ale potřebuji pouštět klávesou X toto:

var texture1 : Texture2D;
var texture2 : Texture2D;
var texture3 : Texture2D;

function Start(){
changeTexture();
}
function Update () {
}
function changeTexture () {


var i= 1;

yield WaitForSeconds(1);
renderer.material.mainTexture = texture1;

yield WaitForSeconds(1);
renderer.material.mainTexture = texture2;

yield WaitForSeconds(1);
renderer.material.mainTexture = texture3;



}
