4. Write:
#pragma strict
function Start () {
}
function Update () {
if (Input.GetKey ("up"))
print ("up arrow key is held down");
if (Input.GetKey ("down"))
print ("down arrow key is held down");
}
7. ‘Play’ button> press up and down arrow> BOTTOM LEFT you will see ‘up arrow key is held down’ or ‘down arrow key is held down’
UP – DOWN – HELD
#pragma strict
function Update ()
{
var down = Input.GetKeyDown(KeyCode.Space); // giu

AUTO FIRE SAMPLE – RILEVA LA PRESSIONE PROLUNGATA, RITORNA ‘TRUE’ DURANTE TUTTA LA PRESSIONE
Returns true while the virtual button identified by buttonName is held down.
Think auto fire – this will return true as long as the button is held down.
Use this only when implementing action like events IE: shooting a weapon.
Statement: static function GetButton(buttonName: string): bool;
buttonName -> virtual Axes button names
Virtual Axes and buttons can be created in: MAIN TOP MENU> Edit> Project Settings> Input.
Example:
// Instantiates a projectile every 0.5 seconds,
// if the Fire1 button (default is Ctrl) is pressed.
var projectile : GameObject;
var fireRate : float = 0.5;
private var nextFire : float = 0.0;
function Update () {
if (Input.GetButton ("Fire1") && Time.time > nextFire) {
nextFire = Time.time + fireRate;
var clone : GameObject =
Instantiate(projectile, transform.position, transform.rotation) as GameObject;
}
