Input.GetKeyUp

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 Conventional Game Input. 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 UnityEngine;
using System.Collections;

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

Description

Возвращает true только в том кадре, в котором пользователь отпустил клавишу, идентифицированную параметром key перечисления KeyCode.

using UnityEngine;

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