There is a variable called 'Touching Ground?' (not to be confused with 'touching') and what I want to do with this variable is check if the 'Player Hitbox' sprite is touching the 'World Hitbox' sprite by saying 'true' or 'false', however I'm confused because it always says 'false' when I put this code in somewhere in the code of the 'Player Hitbox' sprite:

set [ Touching Ground? v] to <touching [World Hitbox v] ?>

Is there a solution?
(Also I don't want the variable to detect just the ground so ignore the name)

By the way, the project is for this collab called Velocity Drive which is hosted by @TailsANDAggressiveOM, and if you want to help make this collab, go into this project: https://scratch.mit.edu/projects/1352759473/

The problem is that your collision code fixes the overlap before the variable can update. To change that you can put the variable update right before you do collisions.
If you solely want to know if you’re touching the ground and not if you’re touching the walls you can do this:
In your

define Move - in steps (Steps)

custom block right after

change y by ((speed y)/(Steps::custom))

add the variable update

set [touching ground? v] to <touching (World Hitbox v) ?>

Still says false even when I'm touching the ground
Also meant went the player touches the ground or wall lol

I forgot to mention that you also have to delete the idk custom block that you placed to test the variable.

Could you please save the changes in your project so I can look if you placed everything correctly?

oh yeah it works now but how about the wall detection as well?

Bruh, I just realised I overlooked the logical and simple method. There is already the touching variable. . Delete the touching ground? variable update thing I told you to add. Set is touching ground? to false at the beginning of the move in steps custom block.
In the two if conditions (if touching > 0) add a set touching ground? to true. That is it.

Sorry if I explained it badly. Here it is in blocks:

define Move - in steps (Steps)
set [touching ground? v] to [false]
change [falling v] by (1)
repeat (Steps)
set [last value v] to (x position)
change x by ((speed x)/(Steps))
Check Touching Solid ::custom
if <(touching) > (0)> then
Collide X: Slope or Wall? ::custom
set [touching ground? v] to [true]
end

set [last value v] to (y position)
change y by ((speed y)/(Steps))
Check Touching Solid ::custom
if <(touching) > (0)> then
Collide Y: Ceiling or Floor? ::custom
set [touching ground? v] to [true]
end

end

end

what about touching the walls (again)

Oh, the touching ground variable detects touching wall and ground.
If you want them seperate you will have to make a new variable named touching wall?.
It would look like this:

define Move - in steps (Steps)
set [touching ground? v] to [false]
set [touching wall? v] to [false]
change [falling v] by (1)
repeat (Steps)
set [last value v] to (x position)
change x by ((speed x)/(Steps))
Check Touching Solid ::custom
if <(touching) > (0)> then
Collide X: Slope or Wall? ::custom
set [touching wall? v] to [true]
end
set [last value v] to (y position)
change y by ((speed y)/(Steps))
Check Touching Solid ::custom
if <(touching) > (0)> then
Collide Y: Ceiling or Floor? ::custom
set [touching ground? v] to [true]
end
end

end

It works!!
I'll probably unshare the project until I'm finished (or if there is another bug that I don't know how to fix)
