This is very, very weird. Thinking about interactivity, there is NOTHING MORE interactive than having the viewer moving objects on the screen, c'mon…..yes one can accomplish it with B4W as it is, but you have to be a wizard in coding for troubleshooting etc. So I was very surprised to see that this new released version of B4W DOES NOT bring this awesome feature in logic nodes. yet. Sorry if this is taken as a critic, but so many things can be done with this essential feature. Really, that is weird. And i have read a ton of requests for this already…..happy 2018!!!

I would like to have the viewer click a "File browser" button to add a picture on the background of my 3d scene work done with b4w.
How do I go by doing that? Can anyone help with this?

in other note: what I really like to have done was to accomplish the Nasa interective sample where the viewer clicks and drags…but honestly, only a "scientist in javascript"(figure of speech)…could accomplish good results on that one. i went thru the bone API example and it is scary!!!! ah ah….if you guys know of a step by step tutorial onthat…..love to all!!!!

Back at the initial example: is there a way on "transform object" node on location, rotation to make it go less distance? i went doen as far as 0.001 as "x" numerical value and still goes too far when clicked. I need to go less than that…it goes toofar for my purpose. Is this set to pixels? is there a way to change the units measure??
Do you know what I mean?
Also could someone direct me to where I get practical details on where it is better to go parent, local or world? maybe it is too much to ask…sorry …i thank you so much for everyone here..

Thank you so much!! I will try !

what about this?

Guys its is so awesome that you are helping!!! im sorry i wasnt clear in my idea…i actually could not return to my desk till now…
well i hear you guys…but to be more clear what i am trying to do is to have one bone moving independent from the other in a way for example that just one hear moves, and not the whole armature.
How do i go by parenting ? if i select the bone it selects the whole armature. I am new to this. I also try to do one armature to each bone in another project, so b4w wd see only armatures, but when I did this, the bones got disconnected and I didnt get them to move the mesh again.

So what about now? i didnt work for me (i attached the file)…..i had the impression i had made it work before with an ik to that ear. Empty wont respond…. thank you thank you for any input!!!

Juani, please bear with me on this on last time….
1) Suzanne is a chracter and it has bones;
2) today i was messing with it again and apparently if i am right, if I try to apply any type of constraints to the child bone having a parent such as empties or a mesh, apparently "it wont work"..WHY? Because for what i saw, B4Web does not recognize constraints…i setup "child of" and tried "copy transforms" for parenting and as soon as I go from blender to B4web, it says "it doesnot support constraints!!!"
3) I am getting desperate because i needed this to work; in other words i need a rigged character without controls on which translation is done when click a mesh (whichever) or empty;

Please please you are awesome…find me any solutions possible you can!! i will pay for your time!! and thank you for everything!!!!!!!

"Hello, what you have done is fine, you only need to pair the bone with the empty."
Its awesome that you got back trying to help!! I thank you so much as so far you were the only one…
could you be more specific about "pair the bone with the empty". and do you think it would work?

This is super important for me. If this is not possible, can I hear any suggestions?? I will beforehand say I know too little of coding.
So lets say there is a character that is rigged with bones. Dont laugh as I am knew to this and I am a little embarrassed to ask this. I parented the bones (child of) with empties and they move the joints really good;
So i was expecting to use this tutorial https://www.youtube.com/watch?v=5VLt6szn6xE&t=306s
where a click in the objects causes a cone to go up and another cone when clicked causes the object to go down;

It didnt work or I did it wrong. 1) How can I accomplish this that way? the viewer clicks an object, or an empty and moves the bones?
2) should i try to parent the bones to objects?
Any ideas??
