问游戏中集合与碰撞的摄像机问题

EN

我目前正试图在游戏中编写一个简单的平台游戏，但是当我尝试将相机功能添加到游戏中时，我遇到了冲突问题。

这是我的代码：

为了不使问题太大，我将削减代码的部分，包括运动，碰撞和绘图。

无相机碰撞

这是没有相机的碰撞，因为你可以看到它工作得很好。

与照相机的碰撞

当我添加相机功能时，就会发生这样的情况

如果您想测试它，请从game_loop中删除#并使用相机应用对绘图进行注释。

    # self.all_sprites.draw(self.window)
    for sprite in self.all_sprites:
        self.window.blit(sprite.image, self.camera.apply(sprite))
