I was making a game when I encountered a bug that doesnt let you go up, even if i tried the change y block, in a different script, it still doesnt work. I used this code to move, smoothly.

when green flag clicked
forever
point in direction (direction::variables)
move (((direction::variables)/(15))*(-1)) steps
end

set [direction v] to (direction)

Please share the project, not just a script out of context. We have no idea what ‘direction’ is set to.
