Hello,
do we have a workshop or a guide for "how to create advanced widgets"? Because creating simple widgets is very easy.
I've created already some custom widgets for my company, so i have experiences with that, but now i'm running in an uknown issue. I'm trying to change the bahavior of the existent BarCodeSannner. I want to be able to scan continuously until the user presses the "cancel"-button. For this i copied all needed files, renamed the needed parts so that now we have the original "scan"-widget and the copied "scan2". At the widget "scan2" i've deleted the part where the scanner stops after a successful scan. But it seems that it is failing at the initializing part. i have checked everything and followed the same steps as i did at my other widgets but it doesnt work. this why i need an advanced guide but i cant find anything.
Solved! Go to Solution.

If you could provide more info - I know that there are times when the extension will not load - look into your studio logs. If you wish to share I could take a look
Did you use an existing extension as your start point? If yes
Check out this video that explores how to create an extension which allows you to get a feel for how the extensions are created - you maybe need help beyond this but if you can follow the content let me know

Yes, i made already extensions from existing widgets and it always works. I made also some widgets from scratch. I just think i miss some advanced knowledge and hope someone can help me.
For the video I have no rights to see. Is it possible to view it without registration?

First of all thanks alot for that videos. Even i knew the most of it i learned something new. And now i fixed my Scanner widget.
I'm able to start a BarCodeScanner that will scan continiously. The only issue is, that it works only at the preview as indended. The scanner will catch any input continiously until i press the "x"-Button.
In runtime in iOS it catches only first value and even the scanner is still running, it refuse to catch any value after the first one.
For that I just removed the "scope.stopScan()" at the existing code and hoped that is all i need but it doesn't works.
if (renderer.scanForNextBarCode) {
renderer.scanForNextBarCode(
(scannedValue) => {
scope.me.scannedValue = scannedValue;
//scope.stopScan();
scope.$emit('valueacquired', scannedValue);
},
function (e) {
//Hololens will call this error callback if the user manually cancels the scan
scope.stopScan();
console.log('scanForNextBarCode was manually cancelled or had an error', e);
}
);
}
Anyway i accept that as a solution, because this guide is all i wanted.
Are there more of these Vuforia Studio coding tutorials available?
At best, with the code examples mentioned in the video.
It's hard to find more resources like this.
