In a project that i'm making, i have a script that said:

when backdrop switches to [ background 11 v]
forever
    
repeat until <[z] = [1]>
if <touching [sprite 6 v] ?> then
set [z v] to [1]
change [death v] by (1)
go to x: (-214) y: (-50)
    
end
    
end
    
end

The problem is that when I test it, scratch doesn't register when sprite 5 (CC) is touching sprite 6 and it's only when I go to see inside and test it (ie. drag “touching sprite 6” out and click on it) does it finally register.
pls help

the game is at :
https://scratch.mit.edu/projects/80330940/

Can you share the project? It might be that either sprite 5 or sprite 6 is hidden.

EDIT: Ninja'd

I'm afraid I can't find the script you're talking about. Where is it?

Found it. The problem is that the script repeats until z=1. But z is always 1, so this script terminates immediately. You want to replace it with

<(z) > [1]>

You could rewrite the script as

when backdrop switches to [background11 v]
forever
    wait until <touching [Sprite6 v] ?>
    change [Deaths v] by (1)
    go to x: (-214) y: (-50)
    wait until <not <touching [Sprite6 v] ?>>
end

still not working

Screen shots aren't that useful. We need to look at the project, check what variables are doing and so on.

You do realise that the block

<color [#00ff00] is touching [#0000ff] ?>

needs the first colour to be in the sprite that is running the block? So I'm not sure why the red block sprite is testing for this since it doesn't contain black so looking for black touching yellow is pointless.

I'm not sure why removing those repeat until colour touching colour blocks makes any difference but if you use forever loops instead it seems to work. Mind you I've got things working several times by tweaking things but when I try to repeat it it doesn't work. I do wonder if something is corrupt in the project.
