Just found out that the Three.js example was already implemented in the V3D code examples repository here: Example
I would be very interested in being able to transpose this in something that would be accessible from the puzzle editors. The Transformcontrols addon itself is something I would have definitely used if I knew how to get it to work in a “puzzle” environment…
I could use some help if anyone knows how to do this!

Ok but how?? the puzzle button in the app manager is linking to the app_name.html file, with the visual_logic.xml file as a parameter, and the .js file is called inside the app_name.html file… I don’t see how to make it different for the puzzle editor and the web server.

Here is a simple demo showing the behaviour I do not understand:
Clone demo
Several keyborad inputs will trigger the following steps:

“M” will append a simple cube, add its custom properties (defined in blender) as a new entry in the addedObjectsDictionnary and give it a named material, and a color according to the imported property
“N” will duplicate and rename the first appended cube, move it and COPY the first cube’s key in the addedObjectsDictionnary, as a new key, named after the second cube: duplicate_cube1.
“O” will again duplicate the first cube, rename it duplicate_cube2, move it, and this time, re-import the custom properties to define the new key in addedObjectsDictionnary.
“P” will lastly change the color for duplicate_cube1, and store the new color in the dictionnary for that key.

But you will see that in the dictionnary, the color has changed for both appended_cube AND duplicate_cube1! How is that possible??
A click on the object prints the Object3D javascript object in the console.

I found something quite odd but interesting, that is apparently not in line with what you mentionned here:

They don’t work at all. You can read them, you can change them, but that’s all.

The “Userdata/CustomProps” dictionnary which is part of the Object3D javascript object IS changed when I manipulate my Object with puzzles, even if I do not explicitely tell my application to write the data in the object’s dictionnary.
In other words, in my Application, I create from scratch a custom dictionnary (addedObjectsDictionnary) where I import a blender created CustomProps dictionnary, name it with a new unique ID. This dictionnary is updated when I make modifications on my object (color, position, rotation, etc…), but for some reason, the “Userdata/CustomProps” dictionnary inside the 3D object is also changed!
And the reason why my objects where linked previously (I guess!) was that I did not make the “import customprops” step and simply duplicated my puzzle created dictionnary and asigned a new UID. But inside the 3D object they were still linked.
Here are two screenshots of the console log for one of my objects before and after a modification (obtained with getObjectByName, no other manipulation). And as I said, I never explicitely tell my application to write something in the Object3D object…
Before:

After modification:

Hoping this is clear…?

I found something: it seems that this has to do with custom properties recovered from the original appended gltf file.
For “properly” appended objects, where the custom properties (that I store in a dictionnary) are pulled from the gltf file, everything works fine.
But for “cloned” objects, where I do not write the new objects properties from the original custom properties, but rather copy them from the cloned object, these properties seem to be linked!
Do you know how exactly these custom properties work and how are they linked/updated (if so?) from within the puzzles??

Ok… I will need to investigate deeper. Appending the same object several times works perfectly fine, but cloning causes all sorts of troubles… strange…
