You'll find it easier to spot errors if you learn to indent blocks of code that are contained within brackets - you're currently missing a closing } at the end of the function, and a closing ) on line 2. Also KeyCode.Escape, not esc. Try this instead: function OnTriggerEnter(other : Collider) { if (Input.GetKey(KeyCode.Escape) { Application.LoadLevel (3); } }
