BarCodeScannerBaseBehaviour Class¶

Description¶

BarCodeScannerBaseBehaviour is the component for QR code scan.

(until 1.2.1) You can add this component to any object at any time after EasyAR initiallized, and if QR code detected, event BarCodeUpdate will be triggered. A typical usage is like below. You need to keep the object active if you want below function to work.

private void Start()
{
    var behaviour = gameObject.AddComponent<BarCodeScannerBehaviour>();
    behaviour.EnableOnStart = true;
    behaviour.BarCodeUpdate += OnBarCodeUpdate;
}

private void OnBarCodeUpdate(BarCodeScannerBaseBehaviour scanner, string barcode)
{
    Debug.Log("barcode: " + barcode);
}

(Since 1.3.0) On 1.3 and later, use AugmenterBaseBehaviour.TextMessage to get barcode update.
