I don't know how to jump. I can make it go up forever, but not back down if still holding down jump button.

try having it go to a certain place with the “go to” button. them have it wait one second then go down again

Hello ,

Code will look something like this ,I'm going to use space to jump

When space key pressed

repeat 10
point in direction “0' / up”
move 10
set rotation style to dont rotate

repeat 10
point in direction “180 /down”
move 10
set rotation style to dont rotate

*Just add the costumes
