Questions & Answers
1

i was thinking of using a GUI that flashes an image that says “press Start” …but i want the GUI box not to be visible is there another way to accomplish this ?

the code i used was:

var icon : Texture2D;


function OnGUI () {
	if (Time.time % 2 < 1) {
		GUI.Box (Rect (Screen.width - 160,Screen.height - 35,100,30),icon); 

}

}

2

var icon : GUITexture;

var timing :int;

function Update(){

timing = Time.time;

if (timing % 2) {

icon.enabled=true;}

else{icon.enabled=false;}}}

Sorry the code button does not work(??!!)
