can i scale 1x1x1 cube to make it i.e. 1x2x3?

Code:

Game.Obj* obiekt = Game.World.objCreateNear(*obj, Matrix(Vec(1, 2, 3), Vec(0, -2, 0)));

i thought i can do it by scalling by Vec but it does not work.

If you cube is Static (or any other default Esenthel Obj type)

Code:

void Static::create(ObjParams &obj)

{

   scale   =obj.scale3     (); //<--- THERE

   mesh    =obj.mesh       ();

   material=obj.material   ();

   phys    =obj.phys       ();

  _matrix  =obj.matrixFinal().normalize(); _matrix_scaled=_matrix; _matrix_scaled.scaleOrn(scale); <-- AND THERE

   if(phys)actor.create(*phys, 0, scale).matrix(_matrix)

                .obj   (this)

                .group (AG_STATIC);

}

as you see above funtion create() rescale object to obj.scale3()

Tested it on static object and it works, but my object is extended from Game::Item and variable 'scale' is flt there, so i cant scale it in 3 dimensions? only kinematik objects can be scaled in 3d?

Code:

class Item : Game.Item

{

   Vec scale;

   Matrix matrix()                  {return _matrix;}

   void matrix(C Matrix &matrix)    {_matrix=matrix; _matrix_scaled=_matrix; _matrix_scaled.scaleOrn(scale); }

   Matrix matrixScaled(){return _matrix_scaled;}

   void pos(C Vec &pos) {_matrix.pos=pos; _matrix_scaled.pos=pos;}

   Vec pos() {return _matrix.pos;}

   virtual void create(Game.ObjParams &obj)

   {

      super.create(obj);

      scale   =obj.scale3     (); //<--- THERE

      mesh    =obj.mesh       ();

      material=obj.material   ();

      phys    =obj.phys       ();

      _matrix  =obj.matrixFinal().normalize(); 

      _matrix_scaled=_matrix; 

      _matrix_scaled.scaleOrn(scale); //<-- AND THERE

      if(phys)actor.create(*phys, 1, scale).matrix(_matrix).obj   (this);

      actor.group(5);

      if(Param *par=obj.findParam("fizyka"))fizyka=par.asBool();

   }

   virtual uint drawPrepare() // extend drawing to include requesting for RM_BEHIND mode

   {

      return super.drawPrepare() | IndexToFlag(RM_OUTLINE);

   }

   virtual void drawOutline() // extend drawing to include rendering "behind effect"

   {

      if(mesh)

      {

         //SetBehindBias(mesh->box.h());

         //mesh->drawOutline(Color(64, 128, 255, 255), matrix());

      }

   }

   Bool update()

   {

      //this->pos(actor.pos());

      return true;   

   }  

   protected:

   Matrix _matrix, _matrix_scaled;

}

so...

i made class like this and object is scalled and everything works till i set .kinematic(false), after that actor works like it should(falls down) but mesh is not following actor. Any help?

Change your pos and matrix function similar to this.

Code:

Vec    pos         (                ) {return actor.pos   (      );                }

void   pos         (C Vec    &pos   ) {       actor.pos   (pos   );                }

Matrix matrix      (                ) {return actor.matrix(      );                }

Matrix matrixScaled(                ) {return actor.matrix(      ).scaleOrn(scale);}

void  matrix      (C Matrix &matrix) {       actor.matrix(matrix);                }

Also, the code from Item.create is

Code:

scale   =obj.scale   ();

   mesh    =obj.mesh    ();

   material=obj.material();

   phys    =obj.phys    ();

   if(phys)actor.create  (*phys, 1, scale).matrix(obj.matrixFinal().normalize())

                .adamping(5   )

                .obj     (this)

                .ccd     (true);

So you set some things two times (like mesh), you don't need to call super.create(obj);

I highly recommended to study Object Source Code, you will find a lot of useful information there.

Edit: Also sorry about my first post, it was litle confusing, but I'm glad you figure it out.

dziablo · 10-17-2013 04:14 PM

thank you very much it works, Object source code yeah id love to study that but where can i find it?

Pherael · 10-17-2013 04:17 PM

Ah, sorry, I just remember is probably available only for licensed developers.

I had another problem with that. When i rotated scaled object mesh was in right position but rotation was out of sync with actor this time. i fixed it by changing scaleOrn to scaleOrnL there:

Code:

Matrix matrixScaled(                ) {return actor.matrix(      ).scaleOrnL(scale);}

just mentioning smile

can i scale 1x1x1 cube to make it i.e. 1x2x3?
