make buttons only clickable once

I am have this menu of buttons, when a button is clicked, the screen fades to black and moves on to the appropriate screen

During the fading to black part of this action, the user is still able to click buttons, which causes my program to kinda implode.

So, how do I make it so that a user can only select one of the buttons and then disable all the buttons?

I tried making an invisible background cover up the screen and make the object.isHitTestable = true but it didn’t seem to work.

My buttons are in a display group, so is there something that mass disables buttons?

Add a touch listener to the coverup

Ah, excellent

Thank you
