RaycastHit2D在另一个协同程序处于活动状态时停止工作。 Unity2D Platformer，W ebGL

Question

我正在开发Unity项目，它是经典的Mario风格2D Platformer。发生的问题是与一个已知的敌人[[Snail相关，当被击晕时可以将其踢开。

[有两个功能，两个都可以单独使用，但不能一起使用。项目Build已导出为WebGL，可以在浏览器中播放。

1。 ChangeDirection：

ChangeDirection（）是一个协程，在开始功能中被调用。当到达平台末端时，它会翻转蜗牛的精灵和运动方向。

2。 CheckCollision

：在更新功能中调用CheckCollision并检测附着在蜗牛上的4个游戏对象上的碰撞。

问题描述

：当我在Start-Function内注释

“ StartCoroutine（ChangeDirection（））;”

时，CheckCollision正常工作。蜗牛被打晕后，我可以把它打晕并踢开。当我将ChangeDirection（）-Coroutine放回原位时，蜗牛会完美地改变其方向。还可以检测到top_Collision。我可以使蜗牛眩晕，它会更改动画并停止移动，但是左右碰撞似乎停止工作，因此我

无法将蜗牛踢开。假设

：ChangeDirection（）协程不会完全阻止CheckCollision（），因为检测到顶部碰撞仍然有效。 topHit是Collider2D，而leftHit和rightHit是RaycastHit2D。由于某种原因，RaycastHit2D无法与同时激活的ChangeDirection（）协程一起使用。
