I'd like to build a permanant movement from up to bot and bot to up for my sprite object
I have a sprite object and i'd like this :
If this Object <= to Y.position(0px):
Object move 1 pixel at angle 90 (going to bottom)
If this Object <= to Y.position(100px)
Object move 1 pixel at angle 270 (going to top)
Can you help me please ?
