Learn how to create a countdown timer in Scratch!
First, open the Variables tab and create a new variable named "timer." Choose whether it's for one sprite or all sprites, then click OK. This will create a new timer variable in the Variables tab.
Select an event block to start the timer, then attach a "set variable" block to set the timer variable to 5 (for a five-second timer). Add a "repeat until" block inside this block, with a "less than" operator comparing the timer variable to one.
Inside the "repeat until" block, add a "wait one second" block and change the timer variable by -1. This will make the timer count down until it reaches zero.
You can add code at the end to stop all other code or broadcast a message like "game over" when the timer reaches zero.
