any way to increase speed every time it hits paddle in brick breaker game with pygame

Question

I'm making a brick breaker game and I want to increase speed every time it hits the paddle. But when I add 1 in the speed for some reason it increases multiple times. here's my code

 if ball.colliderect(paddle):
        y_positive = False
        y_negative = True
        ball_speed += 1

Answer 1

That's because it's happening every clocktick that their collisionbox overlaps. They might be touching for a few frames before they are far enough apart to no longer be considered colliding. You need to put in logic to allow only one increment per volley.

volley = False  ##  only allow increment once ball crosses midpoint of screen
if ball.x > screen_width /2: volley = True

if ball.colliderect( paddle ) and volley:
    y_positive = False
    y_negative = True
    ball_speed += 1
    volley = False

Alternatively, once the ball touches, nudge it far enough away from paddle to ensure that their collisionboxes don't touch.

if ball.colliderect( paddle ):
    y_positive = False
    y_negative = True
    ball_speed += 1
    ball.x += ball.width /2

Nudge it however far it needs.
