Input.anyKey 任意键？

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	void Update() {
		if (Input.anyKey)
			Debug.Log("A key or mouse click has been detected");

	}
}

// Detects if any key has been pressed.
//检测是否某一按键被按住

function Update() {
	if(Input.anyKey)
		Debug.Log("A key or mouse click has been detected");
}
