我试图通过游戏控件来监听一个虚拟游戏对象上的MenuControl，如果菜单打开则控制鼠标控制失效。打开菜单的操作将触发此事件。然后，监听器（在本例中为字符控制器）将停止移动脚本中的移动脚本（释放光标）。 我似乎无法从另一个脚本声明一个类的实例。出于某种原因，当我尝试声明MenuControl类的实例时，它会对我大喊大叫。请帮忙。
public MenuControl menuControl;

private float timePassed = 0f;
public float delayTime = .1f;
public KeyCode MenuKey = KeyCode.M;
// Use this for initialization
public delegate void OnMenuOpen(bool menuOpen); // declare new delegate type
public event OnMenuOpen notifyMenuOpenObservers; // instantiate an observer set
void Start()
{
canvas = FindObjectsOfType<Canvas>();
canvas[1].enabled = false;
}
// Update is called once per frame
void Update()
{
}
public void ToggleView()
{
print("hello world");
}
private void FixedUpdate()
{
timePassed += Time.deltaTime;
if (Input.GetKey(MenuKey))

MenuControl是一个游戏对象，因此需要将其声明为您想要实例化的GameObject。
public GameObject MenuControl;
然后，当您需要对象的属性时，您想要访问对象的脚本
MenuControl.GetComponent<MenuControl>().MyProperty
