I had ported Sky Maze 3D to WebGL.

Game code is still in Java. Transpiled into JavaScript via JSweet transpiler. Instead of JPCT, she now makes use of three.js JavaScript 3D library via JSweet threejs candy.

UI code is also written in Java using GWT, then compiled into JavaScript.

Game is complete with all the original levels. Music, high scores and some UI elements are missing.

I was working on this project during corona times, but possibly I will never finish it. And worse yet, JSweet server and their repository is down nowadays 

The game can be found here.
The controls are: arrow keys, space and control

And the source code is here.

Cheers,

that's a weird question AGP!

I dont have an IDE ATM either. use grep and look closer at the results.

that's correct, every Animated3D must share the same skeleton to be in the same AnimatedGroup.

I cant see anything breaking the animation in that method.

isnt this always returning false?
if (lastClip.getSkeleton().equals(objects[0].getSkeleton()) && lastClip.getSkeleton() != objects[0].getSkeleton())

like
if (a.equals(b) && a != b)

Difficult to make a comment without knowing how you are actually importing/reading the data.

Source code of Bones moved to GitHub.
https://github.com/raftAtGit/Bones.

The latest downloadable zip file can be found at releases page.

Of course this doesnt mean, Bones is moving away from jPCT community. It's a library for jPCT after all

The primary feedback and question medium will still be jPCT forums as mentioned in the feedback section.

This was something I wanted to do since long time, to get rid of the burden of keeping the source code safe. Cloudforge, the previous host of Bones' code is closing, so this looked like the proper time to do that.

Egon, can you please update the links

sorry for the late answer, somehow I didnt receive the notification email.

BonesIO class reads and writes using Java serialization. Java serialization preserves objects references.

So, as long as SkinClips and SkinClipSequences share the same Skeleton instance when they are written by BonesIO, they will share the same Skeleton instance when read by BonesIO.

not sure what's asked here, but loaded SkinClips and SkinClipSequences share the same Skeleton instance.

Well, you are in control of starting an animation sequence and starting audio callback, you can do both at the same time and stop audio when you decide to stop animation sequence. or vice versa, stop animation sequence when audio ends.

Is this a Vuforia question or Bones question?

for Bones, there is no such thing of stopping animation, because there is no such thing of starting an animation.

okay, exposed a copy of internal data structures in JointChannel. please re-download.

hope this helps

SkinClip is the analogue of sub sequence in jPCT's Animation class. It's for whole skeleton, JointChannel is only for a joint in skeleton.

I can expose the internal data in JointChannel, but may not be trivial to split a channel's animation into shorter ones.

It's a bit weird EasyOgreExporter doesnt support multiple animations, it's written 'multiple Skeleton Animations' in their web page. Anyway, if that is the case, I would suggest, export each animation into a different file, and merge them with Bones, so you will end up with separate animations. merging can be done either with scripts (multiple input files) or programatically with AnimatedGroup.mergeAnimations(..) method.

yup, supposed to be

well, as the Javadoc says, SkinClip.iterator() may return null values, just skip null ones in your code

/** <p>Returns an iterator of channels. Note some channels may be null.</p> */
public Iterator<JointChannel> iterator() {
return Arrays.asList(channels).iterator();
}
