JavaScript => public static var anyKeyDown: bool;
C# => public static bool anyKeyDown;

Description 描述

Returns true the first frame the user hits any key or mouse button. (Read Only)

在用户按下任意按键或鼠标按键首帧返回true（只读）。

You should be polling this variable from the Update function, since the state gets reset each frame. It will not return true until the user has released all keys / buttons and pressed any key / buttons again.

你可以在Update方法中轮流检测这个变量，该状态在每帧会得到复位。除非你松开（释放）所有的按键/按钮然后再按下某个按键/按钮，否则不会返回true。

JavaScript:

	// Detects if any key has been pressed down.
 
	function Update() {
		if(Input.anyKeyDown)
			Debug.Log("A key or mouse click has been detected");
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Update() {
        if (Input.anyKeyDown)
            Debug.Log("A key or mouse click has been detected");
 
    }
}
