Based on the picture you linked, I have a couple of suggestions:
-
Your “Counters” is either not the current Game State or is not a game state (You can set your Game State in the project setting under Maps & Modes)
-
For your Casting, you only need to cast once, Incrementing the value automatically sets it, so You do not need the second cast.
-
Your Touch event does not look like it is bound to a specific object or actor (to do this simple select the component in the component tab and then right click and use the add event category)
Hope this helps!
