[Kohjoz]

hey i have a question im creating a simple shop system but when a player buys something from the shop i wanna disable the button that they only can buy it once is there a simple way to do this?

Single player game or multiplayer? Is there a "sign in" required?

If you're using UMG - you can disable the button after they click on it. You'd need to save that info though if you wanted that to persist through multiple gameplay sessions (instances).
