我不知道如何在 pygame 中让一个矩形站在另一个矩形上

Question

我正在尝试制作一个简单的 2d 跳跃游戏，我制作了一个跳跃的立方体和一个简单的平台（地图），如果我像 print("collided") 一样测试它，碰撞会起作用，但我不知道'知道如何使矩形站在另一个矩形上，

tile[1] 实际上是从名为 tile_list 的列表中循环的所有图块（块）。在 tile_list 中，它们是保存的图块。 self.rect_img = img.get_rect() <- 是我希望玩家站立的矩形对象，但我怎么说，它在列表中循环所以我需要使用 tile[1]

我尝试使用：

for tile in self.tile_list:
    collide =  tile[1].colliderect(self.player_rect.x,self.player_rect.y,PLAYER_WIDTH,PLAYER_HEIGHT)
    if collide:
        tile[1].top =  self.player_rect.bottom

但是没有用，玩家（self.player_rect）以某种方式将第二个矩形推到它下面。完整代码 main.py:

此外，如果你想测试代码，游戏会创建 2 个文件，main.py 和 mapdata.py（即 tilemap），并更改照片

Answer 1

你需要改变玩家的位置而不是方块的位置，你还需要设置玩家的y属性：

self.player_rect.x = round(self.x)
self.player_rect.y = round(self.y)

for tile in self.tile_list:
    if self.player_rect.colliderect(tile[1]):
        self.player_rect.bottom = tile[1].top
        self.y = self.player_rect.y
