我有一个2D角色控制器和控制器的一部分是双跳的能力，但如果我的球员击中敌人时，在空中后，双跳或下斜线攻击的球员开始走在一条直线在空中，我假设我错过了地面检查，但不知道我是否可以有任何帮助，请：
CS代码为：

我很抱歉，这是有点长，我削减了部分是关于攻击或一些无关的东西，试图限制有多少在这里。
基本上，如果我双跳，然后击中/向下击中或接触敌人，而我仍然在空中我的球员冻结在该轴，只能左右移动，但动画仍然工作正常。
有点困惑，这需要一些帮助，请，也让我知道，如果我没有给足够的信息的问题：）
我试过在击中后切换inAir布尔，但它似乎对这个问题没有帮助。我希望球员只是再次下降，而不是停留在空中移动
