I have a problem with a GUI test i’ve been doing. i’m trying to clear a Text field when the player hits a key. i have all the inputs set up and everything should work ,but i cant get it too. Here’s the code i’ve been using to try to do this:var string:String; function OnGUI () { string = GUI.TextField (Rect (100, 135, 200, 20), string , 25); } function Update() { if (Input.GetButtonDown("enter")) { string = ""; }

Don’t try to mix Input with OnGUI code.

var s : String;

function OnGUI () {
	var returnHit = (Event.current.type == EventType.KeyDown && Event.current.keyCode == KeyCode.Return);
	s = GUI.TextField (Rect (100, 135, 200, 20), s, 25);
	if (returnHit) {
		s = "";
	}
}

That can be made a little shorter by using the actual character instead (since TextField eats the KeyCode.Return event it has to be checked first):

var s : String;

function OnGUI () {
	s = GUI.TextField (Rect (100, 135, 200, 20), s, 25);
	if (Event.current.type == EventType.KeyDown && Event.current.character == "

"[0]) {
s = “”;
}
}
