i am unfamiliar with JavaScript, and wanted to add an mp3 file to play when the wikitude world starts, however it is not playing. there is no audio,
i used the tutorials on the wikitude website to add wikitude as part of an Android app.
documentation for class sound of wikitude sdk
http://www.wikitude.com/external/doc/alr/Sound.html
here is the code selection for the audio
streamingSound = new AR.Sound("assets/soundtest.mp3", {
onError : errorLoadingSound,
onFinishedPlaying : readyToPlay,
onLoaded : readyToPlay,
});
streamingSound.load();
streamingSound.play();
here is the full code for the file multiplepois.js
var World = {
markerDrawable_idle: new AR.ImageResource("assets/lion.png"),
// New: a second image resource which represents a selected marker
markerDrawable_selected: new AR.ImageResource("assets/marker_selected.png"),
// New: a array holding a reference to all marker objects
markerList: [],
init: function initFn() {
AR.context.onLocationChanged = World.onLocationChanged;
// New: a custom callback which will be invoked when the user taps on an empty screen space
AR.context.onScreenClick = World.onScreenClick;
},
onLocationChanged: function onLocationChangedFn(latitude, longitude, altitude, accuracy) {
AR.context.onLocationChanged = null;
streamingSound = new AR.Sound("assets/soundtest.mp3", {
onError : errorLoadingSound,
onFinishedPlaying : readyToPlay,
onLoaded : readyToPlay,
});
streamingSound.load();
streamingSound.play();
}
// New: Markers are now created using the new operator.
// The marker definition is in `marker.js`.
// Title, description and location are supplied in the json compatible format
var poiData = {
"latitude": 31.580,
"longitude": 130.545,
"altitude": altitude,
"title": "Marker 1",
"description": "forever office"
};
World.markerList.push(new Marker(poiData));
poiData = {
"latitude": latitude,
"longitude": longitude - 0.5,
"altitude": altitude,
"title": "Marker 4",
"description": "West"
};
World.markerList.push(new Marker(poiData));
},
onScreenClick: function onScreenClickFn() {
for (var i = World.markerList.length - 1; i >= 0; i--) {
if (World.markerList[i].isSelected) {
World.markerList[i].setDeselected(World.markerList[i]);
}
}
}
};
World.init();
You can use the ADE (ade.js) included with the SDK to check for any js errors using a desktop browser. JS errors will be reported on Android in logcat as well. However depending on the phone this might be hard to spot.
Checking your code with the ADE in a desktop browser reveals that:
Uncaught ReferenceError: errorLoadingSound is not defined
If you just want to play the sound:
streamingSound = new AR.Sound("assets/soundtest.mp3");
streamingSound.play();
