the first is by using tap as control flow, you can easily implement pause button
the second by directly start the loop in listenter, more straightforward approach

Can't i hold on to line 125 until click event is found?

And won't the above idea just start/end the game instead of holding the control flow?

Thankyou very much 🤗

Answer 7

use if(!tap) inside the game loop.

Answer 8

add new global variable for the game switch

var gameswitch = false;

in main() check if the gameswitch is true to continue

if(!gameswitch) return;

now you can modify the gameswitch value from somewhere else to control (start/suspend) the game flow, in your case in startOverlay screen

Answer 9

to start ? then just put setInterval inside the overlayListener
