我现在正在制作游戏，但遇到了碰撞检测问题。我正在制作一个关卡结束 block ，但它无法检测玩家是否站在其上以更改为第 2 级。该 block 的碰撞检测可在player.updater() 中找到。除此之外，该 block 是一个类，位于一个名为 endPlatform 的组中，以允许碰撞检测工作。游戏运行得非常好，但是它无法检测到玩家何时到达 Endplatform。我没有收到任何错误。
结束平台:
class EndPlatform(pygame.sprite.Sprite):
def __init__(self, display):
super().__init__()
self.image = pygame.image.load("endPlatform.png")
self.rect = self.image.get_rect()
display.blit(self.image, self.rect)
玩家:
class Player(pygame.sprite.Sprite):
def __init__(self):
super().__init__()
# Is it touching the floor?
self.standing = True
# Rendering image and creating some variables
self.image = pygame.image.load("Slime.png")
self.sprite_x_change = 0
self.sprite_y_change = 0
self.rect = self.image.get_rect()
self.rect.y = 460
self.rect.x = 120

def updater(self, platforms, powerups, score, endPlatform):

self.standing = False
platforms_hit = pygame.sprite.spritecollide(self, platforms, False)
for blocks in platforms_hit:

elif self.sprite_x_change < 0:
self.rect.left = blocks.rect.right
self.rect.y += self.sprite_y_change

for blocks in platforms_hit:
# Going down

# Going up
elif self.sprite_y_change < 0:

最佳答案
看来我发现了问题，由于某些愚蠢的原因，你不能在同一个对象上使用两次碰撞检测。我使用它一次是为了让玩家能够站在方 block 上，另一次则是为了让你可以进入下一个关卡!
关于python - 碰撞检测在 pygame 中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33922546/
