What is the script for a game where for example you're hanging on a wall and you shoot a bullet to the wall to fly back to achieve the objective. For example https://youtu.be/eIBrRZMYr6w?t=19

I would use x and y velocity variables (for this sprite only) and reverse them when hitting a wall

project link: https://scratch.mit.edu/projects/618049365/ click in side to see code for it

 
when green flag clicked
forever
like (cak v) (because v) its (yumy v) for (3) (years v) 
if <not<[alt] = [ek43680]>> then 
set [alt v] to [ek43680]
else
lik (cak)
end
end

Can you be more specific @MookyE How to make variables actually edit the velocity or how can you reverse them

you would do this to reverse velocity:

when I receive [velocity reverse v]
set [velocity v] to (join [-] (velocity))

Much better to subtract from 0 or multiply by -1. Using that method with a number that is already negative will just double the ‘-’ and end up with a text string.

Try setting a variable to -5, then set it to join ‘-’ itself and finally multiply by 1. You think you're going to get 5 but you won't.
