I am trying to make a sprite go up until it is not touching a different sprite, however i want it to do this immediately. i put it into a run without screen refresh block, but running it makes the sprite go WAY higher than it should. without the run without screen refresh block, it works fine, but it is way too slow. Here is the code

define up
repeat until <not <touching [sprite1 v] ?>>
change [scrolly v] by (1)
end

for some reason, this sends the player SUPER high instead of just ontop of the sprite
