Make the QR / Barcode Scene
Create the new scene.
Delete the Main Camera that exists by default and add 'Assets > MaxstAR > Prefabs > ARCamera' to the scene.
※ If you build an application, you must add a License Key to ARCamera.
Create an empty object and add 'Assets > MaxstARSamples > Scripts > CodeScanSample' as a component.
Add a button and two Texts. And then drag and drop those elements into the GameObject's Insepctor window.
Set the StartCodeScan () function in the Click event of the Button.
When you press the 'play' button and scan the QRcode/Barcode with the camera, the value of the code is augmented on the screen in the Text position.
Start / Stop Reader
To start / stop Reader, refer to the following code.
>CodeScanSample.cs
void Update() { ... TrackerManager.GetInstance().StartTracker(TrackerManager.TRACKER_TYPE_CODE_SCANNER); ... } void OnApplicationPause(bool pause) { ... TrackerManager.GetInstance().StopTracker(); ... } void OnDestroy() { TrackerManager.GetInstance().StopTracker(); TrackerManager.GetInstance().DestroyTracker(); }
