Pygame，当玩家的头撞到方块（瓷砖）时如何进行碰撞

Question

当玩家的头撞到方块时，我不知道如何进行碰撞。当它用头从底部撞到方块时，它就会向上“传送”。当玩家水平击中方块时也会发生同样的事情，所以如果 self.x 或 self.player_rect.x 击中方块，它会将玩家向上传送。

所以基本上，如果玩家的头撞到方块上，那么玩家就需要倒下。如果它水平击中它，那么玩家 X，那么玩家需要停止移动。

我试过这样做：

#COLLISION WITH BLOCKS
for tile in self.tile_list:
    if tile[1].colliderect(self.player_rect):
        if self.player_rect.y > 0:
            self.player_rect.bottom = tile[1].top
            self.y = self.player_rect.y
        elif self.player_rect.y < 0:
            self.player_rect.top = tile[1].bottom
            self.y = self.player_rect.y

但没有帮助。 tile_list 是实际保存瓦片的列表。我循环遍历该列表以检查所有瓦片（块）并进行碰撞。但是我的玩家可以站在方块（方块）上，但我想让它变得更好，所以我只希望我的玩家在碰到方块时不要传送's.y 或 x.

我认为在使用 pygame 时，如果使用 pygame sprite class :

会容易得多

您可能需要此功能进行碰撞。

# this function is used when there is one object collides with many objects
if pygame.sprite.spritecollide(player,power_pellets,false):
    # do something

您可以使用的另一个函数是：groupcollide(...

#this function is used when a group of objects collide with other group of objects.
collide_with_wall = pygame.sprite.groupcollide(smart_ghost, walls, False, False)
if collide_with_wall:
    # do something

要使用pygame精灵，你需要从pygam精灵继承它class

class Player(pygame.sprite.Sprite):
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image_origin = pacman_img  # use this technique when rotate many times
        self.image_origin.set_colorkey(BLACK)
        self.image = self.image_origin.copy()
        self.rect = self.image.get_rect()  # second mandatory
def update(self): # 
# do something here
