@hinato: You’ve created your own invisible walls, then? The default hex ones only block one direction and are probably not ideal to your uses, since you always want to block at least three directions in your case. If you’re worried about performance, UE4 can handle a huge amount of invisible actors without any performance hit, so it shouldn’t be an issue unless you’re using massive grids with tons of walls
@Wisdom: Hinato’s method looks good, but if you only need something very simple and basic you can do what I do with the “Player/Enemy turn” stuff in the HUD. I use a simple interface and change the text of the string to what is needed. To make it invisible after a few seconds you can just set visibility after a delay or even just change the text to an empty string if you want to be really lazy. HUD stuff is really not my forte, but I’ll be looking into it more in future updates.
