Input.GetButton

Parameters

Returns

bool True when an axis has been pressed and not released.

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. The buttonName argument will normally be one of the names in InputManager such as Jump or Fire1. GetButton will return to false when it is released.

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 fireDelta : float = 0.5;

private var nextFire : float = 0.5;
private var newProjectile : GameObject;
private var myTime : float = 0.0;

function Update () {

    myTime = myTime + Time.deltaTime;

    if (Input.GetButton("Fire1") && (myTime > nextFire)) {
        nextFire = myTime + fireDelta;
        newProjectile = Instantiate(projectile, transform.position, transform.rotation);

        // create code here that animates the newProjectile

        nextFire = nextFire - myTime;
        myTime = 0.0;
    }
}
