Create sub objects in editor
Hello,

I create new object type in editor and I would like join to this object other sub objects from object template.
My two questions:
1. How can I change position sub object when I change position its parent object?
2. How can I create sub object from template. Now I create it like this:
Code:
STRUCT(EditParticles , Edit::ObjClass)
//{
    // ...
};

void EditParticles::create(Game::ObjParams &obj)
{
    for(UInt i=0; i<obj.sub_objs.elms(); ++i)
    {
        Edit::World.objCreate(Vec(0,0,0), &obj.sub_objs[i]);
    }
}
Objects are created but they are empty. Anyone know why?

RE: Create sub objects in editor
Asked are outdated. I worked it out with these problems.
But there was another problem. When I want to move the parent object, its sub objects copy to a new location and I have one parent and a few the same sub object in different positions. How do I move the parent, so that the children remained in the same relationship?
I create sub object in this way:
Code:
void CBaseObjClass::create(Game::ObjParams &obj)
{
    for(UInt i=0; i<obj.sub_objs.elms(); ++i)
    {
        Edit::World.objCreate(obj.matrixFinal().pos, &obj.sub_objs[i]);
    }
}

The second question. Why is not it possible to get an array of objects selected?
At this point, a way to determine which object is selected, it is very brutal.
Code:
    for(int i=0; i<Edit::World.objs(); ++i)
    {
        if(Edit::World.obj(i).selected() == true)
        {
            // actions
        }
    }

Calling the code for every object in every frame is very inefficient. Or maybe there is another way?

Hello,

This is not the right approach to create secondary objects,
as CBaseObjClass::create (in Editor) may be called multiple times, everytime the object has been modified.

I can add accessing selected objects for next SDK

if you don't wish to wait you can add following methods to "Edit/World/WE.h"
Code:
Int  selObjs(     )C {return  _obj_sel.elms();} // get number of selected objects
Obj& selObj (Int i)  {return *_obj_sel[i]    ;} // get i-th      selected object

Thanks! I'll wait for next SDK and surprise, mentioned in the roadmap. wink This access to selected objects will be better.

But I would like to ask you for help in creating sub objects. Generally, a useful improvement would be a group of objects, but as long as it does not exist, I have to do it another way.
Can you hint, how to create sub objects, that were permanently attached to the parent?

Hello,

Groupped objects are on the roadmap

My suggestion would be:
use 1 Edit object in the world Editor, however draw that object as multiple objects:
void objDraw()
{
mesh.draw(matrix);
sub_obj_0.draw(matrix1);
sub_obj_1.draw(matrix2);
}

when it comes to Game, then you can use your method of:
Code:
void CBaseObjClass::create(Game::ObjParams &obj)
{
     for(UInt i=0; i<obj.sub_objs.elms(); ++i)
     {
         Edit::World.objCreate(obj.matrixFinal().pos, &obj.sub_objs[i]);
     }
}
