问题描述
我正在创建一个记忆卡游戏,但是很难更新每个盒子的正确起始位置。第一个for
循环加载每个图像,第二个获取是每个图像的起始位置。当我进行碰撞测试时,它只会回答,因为我的直肠位置没有更新。我该如何更新?

marginx = 45
marginy = 25
class Box():
def __init__(self,image):
self.image = image

if rect.collidepoint(mousex,mousey):

print("hit")
for b in Boxes:
b.draw(screen)
pygame.display.update()
play_game()
解决方法
您必须评估鼠标单击是否在box
对象之一上:
for box in boxes:
if box.rect.collidepoint(mousex,mousey):
clicked_card = True
print("hit")
功能play_game
:
def play_game():
# [...]
while True:
mouse_clicked = False
clicked_card = False
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
elif event.type == MOUSEMOTION:
mousex,mousey = event.pos
elif event.type == MOUSEBUTTONUP:
mousex,mousey = event.pos
mouse_clicked = True
print(mousex,mousey)
for box in boxes:
if box.rect.collidepoint(mousex,mousey):
clicked_card = True
print("hit")
for b in boxes:
b.draw(screen)
pygame.display.update()
