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.

Note: 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;
    }
}
