[SOLVED] loading the world in the editor

[Vladimir_tyutenkov]

C ++ api,

plugin for the editor,

how to determine that the world and all its objects are loaded and ready to work
methods like World :: get () -> Isloaded () do not work

Hello Vladimir,

Still don't understand what do you mean by plugin for the editor. You've made engine plugin and loaded it with the Editor, am I right?

Could you specify what do mean by "ready to work"? All objects are loaded in AppWorldLogic::init and you can work with them.

Thanks.

yes, I created a plugin for a project that loads with it and works with the logic of the editor

class Plugin_Logic : public Unigine::EditorLogic{

//editor
     virtual int init    () override;
     virtual int update  () override;
     virtual int shutdown() override { return 1; }
     //world
     virtual int worldInit    () override;
     virtual int worldShutdown() override;
     virtual int  worldSave() override;
   ...

}

class Plugin_ : public Unigine::Plugin
{
public:
     Plugin_() {}
    ~Plugin_() {}

     virtual int  init    () override;
     virtual int  shutdown() override;

     virtual void update  () override {}

private:
     Plugin_Logic m_editor_logic;
};

I get information about the objects loaded in the editor through the overloaded methods,

as I understand it in the editor, objects are loaded into several streams and getting a link to the object node after loading the world does not mean that the object is fully loaded and in the right position.

in my case there is a world in which there is a landscape object
after loading the world in the editor, the plug-in connected to the editor - downloads objects and arranges them on the surface of the ladscape
at the time of the arrangement of the objects, the Landscaping node is in the editor, but it is apparently not loaded to the end.

I define the loading of the world in the overloaded Unigine :: EditorLogic :: update method

and then I get access to the editor nodes

 auto _world= World::get();
        if(_world)
            if (_world->isLoaded() == 1)
            {           m_terrain_gl_node = ObjectTerrainGlobal :: cast (Editor :: get () -> getNodeByName ("Landscape"));  

            }

but the received nodes , immediately after loading, are not completely ready for work, the editor some time later loads them

As I understood the issue is in scattering objects over terrain. Terrain Global never fully loaded, it's always streamed.

However, you can use force intersection flag to place some object in the not rendered terrain area: https://developer.unigine.com/en/docs/2.9/api/library/objects/class.objectterrainglobal#setForceIntersection_int_void

Please, provide more info if I misunderstood you.

Thanks.

yes all right
with setForceIntersection method everything worked
