关于键盘控制的问题

可以看到 input.anykey 中D比W少得多，
而 input.getkey 中 二者一样多。

测试代码
// Update is called once
private void OnGUI()
{
if(Input.anyKey && Event.current.isKey && Event.current.keyCode != KeyCode.None)
{
// Debug.Log(Event.current.keyCode);
if(KeyboardEvent!=null)
{
KeyboardEvent.Invoke(Event.current.keyCode);
}
}
if(Input.anyKey && Event.current.keyCode!=KeyCode.None)
{
Debug.Log("Input.anyKey " + Event.current.keyCode);
}
if(Input.GetKey(KeyCode.W))
{
Debug.Log("Input.GetKey W");
}
if (Input.GetKey(KeyCode.D))
{
Debug.Log("Input.GetKey D");
}
if (Input.GetKey(KeyCode.A))
{
Debug.Log("Input.GetKey A");
}
if (Input.GetKey(KeyCode.S))
{
Debug.Log("Input.GetKey S");
}
}

根据4楼提示所更正的代码
public class KeyboardControl : MonoBehaviour
{
public UnityAction<KeyCode> KeyboardEvent;
private List<KeyCode> keys;
private void Start()
{
keys=new List<KeyCode>();
}
// Update is called once
private void OnGUI()
{
foreach(KeyCode key in keys)
{
if(Input.GetKeyUp(key))
{
Debug.Log(key + "is Up");
keys.Remove(key);
}
}
if(Input.anyKey && Event.current.isKey && Event.current.keyCode != KeyCode.None)
{
Debug.Log(Event.current.keyCode + " is Down");
if(!keys.Contains(Event.current.keyCode))
{
keys.Add(Event.current.keyCode);
}
}
foreach(KeyCode key in keys)
{
if(KeyboardEvent!=null)
{
KeyboardEvent.Invoke(key);
}
}
}
}
