Callback Examples and available APIs

[ragavendranbala]

Hi, Basically I'm Unity AR developer with C# as my background. So It's feeling like I'm driving a power packed Alien Ship without a user manual (Available APIs and Intellisense). I have checked the AR-NFT-Video_Example.html file, I haven't seen any callback methods are listed on the file to handle the marker lost and found events (Maybe I'm wrong). So I have added my own lines for callbacks. It maybe wrong in some cases, But it's working fine for me for one video and marker. Kindly Add callbacks in the examples.

I'm requesting you to write API Documentation. So that, even peoples having less knowledge in JS and HTML (Like ME) can use this library effectively. If Possible, add me in your Slack Channel, so that i can contribute easily.

@ragavendranbala thank for this issue, i can understand your troubles. I didn't write any API doc because i do the most part of the code. For sure there are many things, improvements and utilities to add. We have a link to slack channel in our website, but probably is expired, you can join us at this link

@ragavendranbala typesctript support is on the way see PR https://github.com/webarkit/ARnft/pull/167 and jsartoolkitNFT has already it. :slightly_smiling_face:

Hi @kalwalt and @ragavendranbala Been scouring the slack channel and this repo can't seem to get the call back for the marker detection working at all. Tried:

        document.addEventListener('getMatrixGL_RH', (ev)=> {
            console.log(ev);
            console.log("FOUND MY marker");
        })

and

        document.addEventListener('matrixGLrhEvent',ev => {
                  //console.log(ev);
          console.log("FOUND MY marker");
            })

With no luck. However the marker lost function: document.addEventListener('nftTrackingLost', function (ev) { console.log(ev); console.log("lost MY marker"); }) Works fine. Any ideas?

Hi @JunkYardRobotBoy which ARnft version are you using?

[JunkYardRobotBoy]

hi @kalwalt I'm using 0.10.0

[kalwalt]

@JunkYardRobotBoy you should add the uuid as in this piece of code:

https://github.com/webarkit/ARnft-threejs/blob/a36b5037b8784f92d44e49c5e1933e9f73831588/src/SceneRendererTJS.ts#L90-L94

@kalwalt - legend, thank you!

got this to work: document.addEventListener('getMatrixGL_RH-' + nft.uuid, (ev) => { console.log("found marker"); }) adding it in after : sceneThreejs = new ARnftThreejs.SceneRendererTJS(config, canvas, root, nft.uuid,true);

Thanks heaps - much appreciated!
