How to change the WTC file of mine?

I worked the samples(image recognition) using Vuzix..

And I want to change the image and tracker(WTC file)..

But It is not easy to me. So guys, plz help me.. :)

var World = {

loaded: false,

 

init: function initFn() {

/* Disable all sensors in "IR-only" Worlds to save performance. If the property is set to true, any geo-related components (such as GeoObjects and ActionRanges) are active. If the property is set to false, any geo-related components will not be visible on the screen, and triggers will not fire.*/

AR.context.services.sensors = false;

this.createOverlays();

},

 

createOverlays: function createOverlaysFn() {

// Initialize Tracker

// Important: If you replace the tracker file with your own, make sure to change the target name accordingly.

// e.g. replace "pageOne" used for creating the AR.Trackeable2DOBject below, with the name of one of your new target images.

this.tracker = new AR.Tracker("assets/magazine.wtc", {

onLoaded: this.worldLoaded

});

 

// Create overlay for page one

var imgOne = new AR.ImageResource("assets/imageOne.png");

var overlayOne = new AR.ImageDrawable(imgOne, 1, {

offsetX: -0.15,

offsetY: 0

});

var pageOne = new AR.Trackable2DObject(this.tracker, "pageOne", {

drawables: {

cam: overlayOne

}

});

},

 

worldLoaded: function worldLoadedFn() {

var cssDivLeft = " style='display: table-cell;vertical-align: middle; text-align: right; width: 50%; padding-right: 15px;'";

var cssDivRight = " style='display: table-cell;vertical-align: middle; text-align: left;'";

document.getElementById('loadingMessage').innerHTML =

"<div" + cssDivLeft + ">Scan Target &#35;1 (surfer):</div>" +

"<div" + cssDivRight + "><img src='assets/surfer.png'></img></div>";

 

// Remove Scan target message after 10 sec.

setTimeout(function() {var e =document.getElementById('loadingMessage'); e.parentElement.removeChild(e);}, 10000);

}

};

 

World.init();

 

I just chaned the parts which marked by red.

But It did not work. I wonder that I have to change more or another code. 

Help me help me

P.S : I add the image using Wikitude tool and then made wtc file.

It all looks good,

Besides checking if the referred png-assets are in pace, also ensure that second param of "Trackable2DObject" equals a valid target-name of your created wtc file (hover the target to double check) see attached file. If you only have one trackable2D in your code also try setting targetname to "*", which will then be used for any defined target inside the wtc.
Also ensure to use wtc file for version 4.0 since Vuzix SDK yet does not support 4.1 wtc-files.

Hope that helps.

Kind regards,
Andreas
