如何在纵向碰撞不存在时检测横向碰撞？
我最近在试着搞模拟生存，在碰撞检测发生了诡异事件

如图，角色正在走向右下角的草方块（必须是右边，左边似乎没有这个诡异事件）
仔细看右下角，人物走到草方块旁时应该碰撞到然后停下，然而却直接走进了草方块，冒出一个小头。请问这个问题有没有解决办法？
先谢谢大家浏览，不过我终于自己想出了解决方案

return 1我加入了这些代码，进行层次判断
if self.floor == sprite.floor and co.x2 in range(sprite_co.x1, sprite_co.x2) and self.x > 0:
self.x = 0在主角的代码中，我加入了这个判断，在层次相同的情况下，如果自己的x2进入了对方x1到x2的序列中，且正在向右移动，则停止移动
