Hey, this is my first post btw.
So I am trying to create a game where you can catch a ball and afterwards it refreshes. However the image of the ball that is supposed to run down the lane skips from screen_width (1280) - 100 all the way to x: 200 when it's updated with self.x -= self.speed. I don't know where it went wrong.

Here's where it starts:
