C# 如何使变量在脚本中的任何位置可见？

CurrentlyGrounded应翻转为true和false。相反，VisualStudio报告它在当前上下文中不存在。如何强制该变量在脚本中无处不在

把它公之于众完全没有任何作用

问题出现在第267行的private void GroundCheck方法中

应该发生的是，它被看到并按预期发生变化

相反，据报道，它在当前环境中不存在。

不要听那些为了更容易地访问内容而想让一切都保持静态的人的话

这实际上可能会导致很多麻烦，只要你有超过一个该类的实例，例如，如果有两个玩家，或者一个AI使用相同的组件

另一个坏的副作用是，您将无法再通过Inspector对其进行配置，例如调试或为其提供所需的启动值

你想用的是

moventSettings.CurrentlyGrounded

访问MovementSettings实例的值

和你做这件事的方式一样

movementSettings.Running

---

您可以将其分配给全局变量

public static class Globals
{
    public static String value = "Sample Value"; // Modifiable
    public static readonly String CODE_PREFIX = "TEST-"; // Unmodifiable
}

然后可以在代码中的任何位置检索定义的值

String code = Globals.CODE_PREFIX + value.ToString();

---

您可以将其标记为静态，并将其用作移动设置。CurrentlyGrounded=true；我将如何实施这些更改？Change public bool CurrentlyGrounded=true；在MovementSettings类中设置为public static bool CurrentlyGrounded=true；并将CurrentlyGrounded的所有用法更改为MovementSettings.CurrentlyGrounded，但仅当在MovementSettings类之外使用时。脚本编译时，它不再能够在true和false之间动态切换。我怎样才能解决这个问题。问题是关于布尔值。。。2.如果您可以简单地将值设置为静态，那么为什么还要引入一个新的专用类呢？3.不要因为不知道如何访问正确的实例而到处使用static。这在长期内造成的问题比短期内解决的问题要多。
