Ich versuche ein Ping-Pong-Spiel in Python zu programmieren, und ich bin in der Lage, den Ball von der Seite des Pads abprallen zu lassen. Allerdings kann ich den Ball nicht von der Ober- und Unterseite des Pads abprallen lassen. Ich mache momentan nur das linke Pad (Pad1). Hier ist mein Code:Ping Pong Pygame Kollision mit der Seite des Pad

Weiß jemand, wie man das macht? Ich habe erst kürzlich gelernt, in Python und Pygame zu programmieren.
[pygame.Rect()] (http://pygame.org/docs/ref/rect.html) hat Methoden Kollision mit Punkt zu überprüfen (dh per Mausklick.) Oder anderen rect - dh. 'ball_rect.colliderect (paddle_rect)' – furas
können Sie 'Rect' auch zum Blit verwenden -' blit (text, text_rect) '. Um Text in die Mitte des Bildschirms zu legen, können Sie nur einmal 'text_rect.center = screen.get_rect(). Center' ausführen und dann müssen Sie dieses hässliche '(width/2) - text.get_width () // 2, (height/4) - text.get_height() // 2) ' – furas
