Input.GetKeyUp

Description

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

Note: This API is part of the legacy Input class, and not recommended for new projects. The documentation is provided here to support legacy projects that use the old Input Manager and Input class. For new projects you should use the newer and Input System Package. (read more).

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

Returns true during the frame the user releases the key identified by the key KeyCode enum parameter.

using UnityEngine;

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