Maybe is easier to drop an eye ? thx.

Thank you very much that fixed the issue I had with js error.
Now I see:
…
B4W LOG: LOAD PHYSICS Using Separate Worker Thread, Max FPS: 60
print.js:49 B4W LOG: PHYSICS PATH http://localhost:6687/src/../deploy/apps/common/uranium.js?t=21042017144151
print.js:49 B4W LOG: PHYSICS READY
print.js:49 B4W LOG: THREAD 0: LOADED CALLBACK
print.js:49 B4W LOG: START NLA

but if I click the 3d elements I did created I see no movement. I will go back and check the tutorial

I did followed the tutorial located at https://www.blend4web.com/en/community/article/23/

After I did adapted my js I did got in the firebug console:

print.js:73 B4W ERROR: app.enable_controls() deprecated

Where I should change or read an updated tutorial ?
Can you maybe update that page if you find is necesary ?

Here is my code (everything generated in the http://localhost:6687 and adapted slightly from tutorial page mentioned above ):

##############
"use strict"

// register the application module
b4w.register("FireWorks_app", function(exports, require) {

// import modules used by the app
var m_app = require("app");
var m_cfg = require("config");
var m_data = require("data");
var m_preloader = require("preloader");
var m_ver = require("version");

var m_anim = require("animation");
var m_scenes = require("scenes");

// detect application mode
var DEBUG = (m_ver.type() == "DEBUG");

// automatically detect assets path
var APP_ASSETS_PATH = m_cfg.get_assets_path("FireWorks");

var _previous_selected_obj = null;

/**
* export the method to initialize the app (called at the bottom of this file)
*/
exports.init = function() {
m_app.init({
canvas_container_id: "main_canvas_container",
callback: init_cb,
show_fps: DEBUG,
console_verbose: DEBUG,
autoresize: true
});
}

/**
* callback executed when the app is initialized
*/
function init_cb(canvas_elem, success) {

if (!success) {
console.log("b4w init failure");
return;
}

m_preloader.create_preloader();

canvas_elem.addEventListener("mousedown", main_canvas_click, false);

// ignore right-click on the canvas element
canvas_elem.oncontextmenu = function(e) {
e.preventDefault();
e.stopPropagation();
return false;
};

load();
}

/**

*/
function load() {
m_data.load(APP_ASSETS_PATH + "FireWorks.json", load_cb, preloader_cb);
}

/**
* update the app's preloader
*/
function preloader_cb(percentage) {
m_preloader.update_preloader(percentage);
}

/**
* callback executed when the scene data is loaded
*/
function load_cb(data_id, success) {

if (!success) {
console.log("b4w load failure");
return;
}

m_app.enable_controls();
m_app.enable_camera_controls();

// place your code here

}

function main_canvas_click(e) {
if (e.preventDefault)
e.preventDefault();

var x = e.clientX;
var y = e.clientY;

var obj = m_scenes.pick_object(x, y);

if (obj) {
if (_previous_selected_obj) {
m_anim.stop(_previous_selected_obj);
m_anim.set_frame(_previous_selected_obj, 0);
}
_previous_selected_obj = obj;

m_anim.apply_def(obj);
m_anim.play(obj);
}
}

});

// import the app module and start the app by calling the init method
b4w.require("FireWorks_app").init();

Thank you

Petronel

ok. thank you once again.

I did fixed it by deleting pythonhome from system variables

:( pfuuuhhh… :)

Should I have PYTHONHOME setup in the System variables or it will be handled by Blender ?

python -E works like a charm

python - ImportError: No module named 'encodings'

is not working ok… it crash
How is supposed to fix it ? I did updated blender to 2.78…

I get 'C:\\Program Files\\Blender Foundation\\Blender\\2.78\\python\\bin\\python.EXE'

what should be done ?

No changes either with 2.7 uninstalled and or 3.6 installed … same

But http://localhost:6687/apps_dev/code_snippets/code_snippets.html?scene=camera_animation works fine and all other
at http://localhost:6687/apps_dev/code_snippets/code_snippets.html?scene=canvas_texture

Only problem with python occurs when http://localhost:6687/project/ is accessed
