Hmm, I don’t know why this should not work. Maybe the game is just not in focus so no input is registering? If you have not already, try clicking anywhere in the viewport after playing in editor and before pressing left or right. If this does not work, try adding a Print String node anywhere in your node structure to see if the events fire at all. If they do, try printing the name of the current unit using PrintString to see if it is empty. If it still does not work, report back to me and I’ll see if I can figure it out.
