public static bool GetKeyUp (string name);

Description

Возвращает true, если на протяжении кадра пользователь отпустил клавишу name.

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.

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.

using System.Collections;

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