Hi! One of my students is trying to use a while loop under the “on A button pressed” event handler. When the condition countdown \> 0 is true, he wants the camera to shake. When he adds in the loop and presses the A button, the code stops running. Any ideas on how to get this loop to run properly? Thank you!

`while (true)` has no exist condition, so it’ll stay in that forever. If he wants the loop to stop when countdown is no longer \>= 0, he’d want something like this:

but in this case there wouldn’t be _that_ much of a difference, because the countdown running out means the game over screen will pop up. Having the loop in the ‘on a pressed’ itself also has some behavior associated with it; on a pressed will only run one at a time, but from the current game it doesn’t seem like an issue (and we could work around if needed).

What would he like to see change in the game behavior wise?
