【问题描述】：
我正在制作游戏，并尝试添加游戏手柄控件。 Unity 自动生成一个类供使用，它返回 3 但同样的错误：
Assets\Scripts\Player2\PlayerControls.cs(78,38)：错误 CS1061：“InputActionMap”不包含“GetAction”的定义，并且没有可访问的扩展方法“GetAction”接受类型的第一个参数可以找到“InputActionMap”（您是否缺少 using 指令或程序集引用？）

我没有仔细查看代码，但错误非常简单。这是说您用于
GetAction的重载不存在。从docs中，只有两个GetAction重载，它们采用string和GUID，没有采用InputActionMap。 编辑：刚刚注意到您说这是从 Unity 生成的。后面可以看一下代码，不过sn-p比较大。
