Hi all, this is an easy one for many game developers but for some reason, I have completely forgotten how to do it. What I am trying to do is make a character run up a road then step on an invisible button. Let's say a call the button "IButton" and in front of me hidden is a wall, I shall call this "Wall". How do I make it when my character runs over "IButton" can I make "Wall" move out in front of me? I have forgotten the nodes which I am supposed to use. Is anyone able to help me Thanks in advance.
