JavaScript => public static function GetKeyUp(name: string): bool;
C# => public static bool GetKeyUp(string name);

Description 描述

Returns true during the frame the user releases the key identified by name.

在用户释放给定名字的按键的那一帧返回true。

You need to call this function from the Update function, since the state gets reset each frame. It will not return true until the user has pressed the key and released it again.

你需要在Update方法中调用这个方法，因为该状态每帧获得重置。除非用户按下这个按钮然后重新释放它，否则将不会返回true。

For the list of key identifiers see Input Manager. When dealing with input it is recommended to use Input.GetAxis and Input.GetButton instead since it allows end-users to configure the keys.

按键的标识符列表可以在输入管理器中找到，当处理输入时推荐使用Input.GetAxis和Input.GetButton，它们允许最终用户自定义按键。

JavaScript:

	function Update () {
		if (Input.GetKeyUp ("space"))
			print ("space key was released");
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Update() {
        if (Input.GetKeyUp("space"))
            print("space key was released");
 
    }
}
