static function GetKeyDown (name : string) : bool

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.

JavaScripts

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

using System.Collections;

void Update() {
if (Input.GetKeyDown("space"))
print("space key was pressed");

}
}

import UnityEngine
import System.Collections

def Update():
if Input.GetKeyDown('space'):
print('space key was pressed')
