Returns true the first frame the user hits any key or mouse button. (Read Only)
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).
You should be polling this variable from the Update function, since the state gets reset each frame.
It will not return true until the user has released all keys / buttons and pressed any key / buttons again.
This does not detect touches. For touches, use Input.touchCount.
using UnityEngine;
public class Example : MonoBehaviour { // Detects if any key has been pressed down.
void Update() { if (Input.anyKeyDown) { Debug.Log("A key or mouse click has been detected"); } } }
