public static function GetKeyDown(name: string): bool;
public static bool GetKeyDown(string name);

Parameters

Description

Returns true during the frame the user starts pressing down the key identified by 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 released the key and pressed 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.

	function Update () {
		if (Input.GetKeyDown ("space"))
			print ("space key was pressed");
	}
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Update() { if (Input.GetKeyDown("space")) print("space key was pressed"); } }
public static function GetKeyDown(key: KeyCode): bool;
public static bool GetKeyDown(KeyCode key);

Parameters

Description

Returns true during the frame the user starts pressing down the key identified by the key KeyCode enum parameter.

	function Update () {
		if (Input.GetKeyDown (KeyCode.Space))
			print ("space key was pressed");
	}
using UnityEngine;
using System.Collections;

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