Fehler beim Klicken auf das gestapelte Bild in Pygame [Duplikat]
Dec 01 2020
Ich habe einige Codes zum Klicken und Ziehen von Bildern erstellt, um sie irgendwann zu stapeln. Bei den ersten Klicks hat es gut funktioniert, aber wenn ich es mehrmals an derselben Stelle gestapelt habe, kann es plötzlich nicht mehr angeklickt werden. Wie kann ich das Problem beheben und wenn Sie in Ordnung sind, können Sie es kompakter gestalten?

smallfont = pygame.font.SysFont(None, 25)
title = bigfont.render("TITLE", True, (0,0,0))

img_path = os.path.join(current_path, "images")

x.drag()

screen.fill((255, 255, 255))

Sie haben das rectAttribut nicht aktualisiert , als die Maustaste losgelassen wurde. Wenn das Bild verschieben, führt dies zu einem Fehler zwischen der Versatz x, yund das rectAttribut:
while True:
for event in pygame.event.get():
# [...]
elif event.type == MOUSEBUTTONUP:
for x in img_list:
for y in place_list:
if x.rect.colliderect(y.rect):
x.x_pos = y.x_pos
x.y_pos = y.y_pos
x.rect.left = y.x_pos # <-- ADD
x.rect.top = y.y_pos # <-- ADD
Allerdings müssen Sie nicht die xund yAttribute überhaupt. Verwenden Sie stattdessen den im Attribut rect gespeicherten Speicherort:
