Unity Script Reference – Input.GetKey

Input.GetKey

static function GetKey (name : String) : boolean

Description

Returns true while the user holds down the key identified by name. Think auto fire.

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.

JavaScript

function Update () {
    if (Input.GetKey ("up"))
        print ("up arrow key is held down");

    if (Input.GetKey ("down"))
        print ("down arrow key is held down");
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    void Update() {
        if (Input.GetKey("up"))
            print("up arrow key is held down");
        
        if (Input.GetKey("down"))
            print("down arrow key is held down");
        
    }
}

        print ("down arrow key is held down");
}
