Input.GetButton

static function GetButton(buttonName: string): bool;
static bool GetButton(string buttonName);
static def GetButton(buttonName as string) as bool

Description

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 events that trigger an action, eg, shooting a weapon. Use GetAxis for input that controls continuous movement.

// 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; Instantiate(projectile, transform.position, transform.rotation); } }

using System.Collections;

            nextFire = Time.time + fireRate;
