Aim with the paddle
Pygame challenges · Bounce, step 3 of 3 · 20 XP
Every hit sends the ball back flat, so the computer always reaches it.
Your task
Write paddle_angle(ball_center, paddle_center, paddle_half). It says where the ball hit the paddle: -1 at one end, 0 in the middle and 1 at the other end, so (ball_center - paddle_center) / paddle_half. A ball that clips the very end can give more than 1, so keep the answer between -1 and 1 with your clamp.
The game multiplies it by 5 to get the ball's new slope: hit with the edge of your paddle to send it steep.
The function is at the top of the program, marked fix this. Press Run to play the game as it is, then Check when your function is ready.
