Key codes returned by Event.keyCode. These map directly to a physical key on the keyboard.

Key codes can be used to detect key down and key up events, using Input.GetKeyDown and Input.GetKeyUp :

#pragma strict

public class KeyCodeExample extends MonoBehaviour { function Update( ) { if( Input.GetKeyDown( KeyCode.Space ) ) Debug.Log( "Space key was pressed." );

if( Input.GetKeyUp( KeyCode.Space ) ) Debug.Log( "Space key was released." ); } }
using UnityEngine;

public class KeyCodeExample : MonoBehaviour { void Update() { if (Input.GetKeyDown(KeyCode.Space)) Debug.Log("Space key was pressed.");

if (Input.GetKeyUp(KeyCode.Space)) Debug.Log("Space key was released."); } }

Keyboard events can also be captured within OnGUI :

#pragma strict

public class KeyCodeOnGUIExample extends MonoBehaviour { function OnGUI( ) { if( Event.current.Equals( Event.KeyboardEvent( KeyCode.Space.ToString() ) ) ) Debug.Log( "Space key is pressed." ); } }
using UnityEngine;

public class KeyCodeOnGUIExample : MonoBehaviour { void OnGUI() { if (Event.current.Equals(Event.KeyboardEvent(KeyCode.Space.ToString()))) Debug.Log("Space key is pressed."); } }
