tkinter跳转并运行游戏画布对象碰撞

Question

我正在尝试使用画布在tkinter中编写一个小的Jump'n'Run游戏，到目前为止它的工作非常好，但我有一个问题，我无法绕过我的脑袋。

看看these three pictures：第一次撞击工作正常 - 我可以从一个桨跳到另一个桨。

在第二张图片中，你可以看到，每当我进入桨下它不会掉下来并且跳起来也是不可能的，可能是因为我在self.y = 0碰撞检测中有self.brick。我怎么能这样工作，即使它在桨下它反弹，因为这很重要，例如当我开始添加第二行桨。

我的碰撞代码：

        def brick_hit(self, pos):
        for brick_line in self.bricks:
            for brick in brick_line:
                brick_pos = self.gamerootCanvas.coords(brick.id)
                try:
                    if pos[3] > brick_pos[1]:
                        if pos[2] > brick_pos[0] and pos[0] < brick_pos[2]:
                            return True
                except:
                    continue
        return False

你应该把自己从砖块上移开以防止卡住。当在砖上休息时，你也应该改变状态以防止抖动。
