Input.GetKeyUp 获取键弹起

# [Input](Input.html).GetKeyUp 获取键弹起

static function *GetKeyUp* (*name* : string) : bool

*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](../MonoBehaviour/MonoBehaviour.Update.html) 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，此后每一帧重置状态时，它将不会返回 true 除非用户按下这个按钮然后重新释放它

For the list of key identifiers see Input Manager. When dealing with input it
is recommended to use [Input.GetAxis](Input.GetAxis.html) and [Input.GetButton](Input.GetButton.html) 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。
