The red cube when the marker is lost, is still visible. This should not happens because in the arNFT_example.html objVisibility = false. Need to be fixed.

In a React environment i get this error:

index.js:1 SyntaxError: Unexpected token < in JSON at position 0
console.<computed> @ index.js:1

This not happens with commonJs (the code inside <script>), and i think probably related to kalwalt/ARnft-ES6-react#16. The issue seems to come from the getConfig function, i will implement the old one with axios, that not caused any issue.

related to the issue #184 (comment) i tried to change the path of the config file:

+ ARnft.init(640, 480, "DataNFT/pinball", '/../config.json', true)
- ARnft.init(640, 480, "DataNFT/pinball", 'config.json', true)

and in the production build works as usual, everything can be loaded. Probably need a different path because i add the extra path?

For the react issue: i got it work with the newest version see https://github.com/kalwalt/ARnft-ES6-react/tree/upgrading-arnft

Back to the objVisibility issue:
The problem is in this routine:

when the msg is null ( i.e. when the NFT marker is lost) and so it is valid if (!msg) { } the world variable is undefined and so the event is skipped, and so the nftTrackingLost is not sent... Probably this routine was ok for Javascript but not converted to Typescript. I can try another solution or temporarly skip this.

In the next days i will add some doc comments for Typescript and i think it will almost ready for merging.

I think i added all the features but i will check in the next days, with a fresh mind.
