Practice makes the AI takes 2 seconds to react and Match makes it so its only 1. And the rotating is supposed to make the ball fly off in random angle when you smack into it so I'll look into that but anyway thanks for the feedback!
Yeah when launching league I understand what was the difference, it's just I didn't think at first it was only a difficulty settings.
I tryed again to see if I didn't understand something with the rotation and the ball, but yeah, it seems it doesn't work it goes where I try to push it (or I'm really lucky °°').
Well at least your answer made made replay it 5 min hitting that poor ball (and the ennemy I have to admit :D).
