I need serious help I am trying to make a game I want to put a timer on it and when the timer reaches 0 I want it to switch backdrop
I put in when green flag clicked if time =0 switch to backdrop 3
but it dos not work please help me

You could use the wait block instead, so wait 10 seconds then change backdrop?
If you're using the timer in sensing then it doesn't count down it counts up. So if you wanted to wait 10 seconds you'd use;

reset timer
wait until timer > 10
switch to backdrop 3

If you really want to make a count down timer then you need to use a variable and a simple way to achieve this is;

when gf clicked
set countdown to 10
forever
wait 1 second
change countdown by -1

If you don't want it to countdown forever then change that block to whatever you need.

Here's the problem with your script. You have
The problem is the if. This script does not constantly sense when the timer = 0. It only senses if it is once and then the script ends. It doesn't repeatedly check if the condition is true. What you can do if put a forever loop around the blocks to make it always check the condition, but the best way to go is to have
To countdown you can use the method above in that post.

Try

Hope this helped.

Please don't use a forever loop for this. It's unnecessary and you risk finding the forever loop is then running at a later stage in your project and still changing the background when you don't want it to. A wait until is much better, giving you much more control and saving you having to stop the script once it has done its work.

I think LucaR10 helped ME the most! But thanks all of you! I'm just a 10 year old with good grammar that's new to coding!
You guys rock! Thx!

You could use this:

This will make it so that every second the timer will go down by 1 from the original number, and will keep doing so until it's 0 at which point the background will change.

Oh, I just realized that this was a necroposted topic. I need to be more careful! Reporting…
