alice-teacher delay question

[James Vanderhyde]

The way to do this is to control the event with logic, rather than a timer. Create a boolean variable called “gameOn” or something like that that is initially false. When the countdown is finished, set the variable to true. In the arrow buttons events, put the action inside an if statement so the movement only occurs if gameOn is currently true.

I’m still on Alice 2, but there should be something similar in Alice 3.

I do not want the user to be able to press the arrow buttons on the keyboard to start a race between two objects until the countdown is finished.  I tried a delay in the event listener but it did not work.
