My users to be able to click a button and go to a game. Once the game is finished the game goes back to the menu, where the button was initially clicked. I want this button to disappear or be disabled for a certain amount of time (Say 30 seconds?) before being able to be clicked again. The users should be able to see a timer count down from 30 seconds and then the button would reappear/be able to be clicked again.
How could I do this?
