hy !
Are you using the project manager?

Hy blend4web heads!
I'm back in my calback adventures !
I am using manfold sensor inspired by petigor tutorials to control a cube.

function setup_direction(){
  var head = m_scenes.get_object_by_name("Cube");

  var key_up     = m_ctl.create_keyboard_sensor(m_ctl.KEY_T);
  var key_down   = m_ctl.create_keyboard_sensor(m_ctl.KEY_G);
  var key_right    = m_ctl.create_keyboard_sensor(m_ctl.KEY_H);
  var key_left   = m_ctl.create_keyboard_sensor(m_ctl.KEY_F);

  var direction_array = [
      key_up, key_down, key_right, key_left
  ];

  var up_logic = function(s){return (s[0])};
  var down_logic = function(s){return (s[1])};
  var right_logic = function(s){return (s[2])};
  var left_logic = function(s){return (s[3])};

  function moveHead_cb(obj, id, pulse, param){
      if (pulse == 1){
        console.log(id, param);
        var head_pos = m_trans.get_translation(obj);
        console.log(head_pos);
        head_pos[param[0]] += param[1];
        console.log(head_pos);
        m_trans.set_translation(obj, head_pos[0], head_pos[1], head_pos[2]);
      }
      else{
        console.log("no pulse");
      }
    };

    m_ctl.create_sensor_manifold(head, "UP", m_ctl.CT_TRIGGER,
        direction_array, up_logic, moveHead_cb, [2,-1]);
    m_ctl.create_sensor_manifold(head, "DOWN", m_ctl.CT_TRIGGER,
        direction_array, down_logic, moveHead_cb, [2,1]);
    m_ctl.create_sensor_manifold(head, "RIGHT", m_ctl.CT_TRIGGER,
        direction_array, right_logic, moveHead_cb, [0,1]);
    m_ctl.create_sensor_manifold(head, "LEFT", m_ctl.CT_TRIGGER,
        direction_array, left_logic, moveHead_cb, [0,-1]);
}
});


after that i added a js callback in a node setup to get a function called every second. Because the snake only moves or chanes direction every Xmillisecond

function setup_direction(){
    m_logic_nodes.append_custom_callback("SNAKEMOVE", snakemove);
    var head = m_scenes.get_object_by_name("Cube");
    var direction = []

    var key_up     = m_ctl.create_keyboard_sensor(m_ctl.KEY_T);
    var key_down   = m_ctl.create_keyboard_sensor(m_ctl.KEY_G);
    var key_right    = m_ctl.create_keyboard_sensor(m_ctl.KEY_H);
    var key_left   = m_ctl.create_keyboard_sensor(m_ctl.KEY_F);

    var direction_array = [
      key_up, key_down, key_right, key_left
    ];

    var up_logic = function(s){return (s[0])};
    var down_logic = function(s){return (s[1])};
    var right_logic = function(s){return (s[2])};
    var left_logic = function(s){return (s[3])};

    function moveHead_cb(obj, id, pulse, param){
        if (pulse == 1){
            console.log(id, param);
            var head_pos = m_trans.get_translation(obj);
            console.log(head_pos);
            head_pos[param[0]] += param[1];
            console.log(head_pos);
            m_trans.set_translation(obj, head_pos[0], head_pos[1], head_pos[2]);
      }
        else{
            console.log("no pulse");
      }
    };

    function setDirection_cb(obj, id, pulse, param){
            //getdirection = getdirection();
            console.log(param)//, getdirection);

    }
    // function getdirection(){
    //     return true;
    // }

    m_ctl.create_sensor_manifold(head, "UP", m_ctl.CT_TRIGGER,
            direction_array, up_logic, setDirection_cb, [2,-1]);
    m_ctl.create_sensor_manifold(head, "DOWN", m_ctl.CT_TRIGGER,
        direction_array, down_logic, setDirection_cb, [2,1]);
    m_ctl.create_sensor_manifold(head, "RIGHT", m_ctl.CT_TRIGGER,
        direction_array, right_logic, setDirection_cb, [0,1]);
    m_ctl.create_sensor_manifold(head, "LEFT", m_ctl.CT_TRIGGER,
        direction_array, left_logic, setDirection_cb, [0,-1]);

    function snakemove() {
        console.log("move");
    }


}
});


So… I wonder if i could use the JSCALLBACK to trigger a sensor, a pulse or something so that it could help trigger the movement only when the JSCALLBACK has been called. I would prefer not to use a global variable.

Is you want more precision please ask. I am a bit confused and not sure how to explain expose my question

None for the moment.
Just that I read some Webgl documentation and I wondered if it was accessible for a blend4web app.

I'm thinking of using a cms, probably typo 3, for my website I would like to add some webgl and blend4web on some pages. Does anyone have experience with that. I wonder how to export my scenes. Probably like the blog post explains with json and the player.

Another question I have is : is it still possible to use Webgl specifications on witch blend4web is build?

Did you export by the project manger every time? Did you change B4W sdk?
Do you use custome JS? If not maybe you ca try making a new_project and saving your blend as new_project and try exporting new_project wich would be a copy of your original blend. A bit hacky but worth a try, maybe?

Hello. There are différent ways to do that. At the moment if you want to use logici tree you could use a use entry point js function. I use one in the project in host on my github. Check out my last topic in the forum

I not sûre. I used the f12 key and search the JS files in the sources and then ctrl f to search the file for materials.
Can't check right now will Asap!

Here is a quick demo of object substitution. If you need to do that with complexe object it might not be a good solution because it multiplies the number of objects in the scene…

What is your knowledge of blend4web ?
Maybe you could start with a simple node setup I'm which you hide reveal different objects when you click on different objects. That may not be ideal but I could setup a node tree for you in a few minutes. But I suck at materials so I can't help you if you want something more complicated.

Hello !
Here is a link to a peronnal project.
It's a kind of personnal page. It is still work heavilly in progress. Still have lot to do. But before i continue working on the details I would like to have some of your impression. Just to check if something obvious isn't working… I have been working on this for a couple of weeks and i really can't tell if it's any good.

So if you have any comments. Feel free to reply !
