Drawing image from ImageAtlas

Hi,
I've just started using Esenthel and I'm pretty newb in programming.
I have a problem with draw function of ImageAtlas.

PHP Code:

void draw(Int part_index, C Vec2 &pos, Flt pixel_size)C; // draw specified part index at 'pos' screen position, with 'pixel_size' 

Everything is fine except position - no matter what vector I pass, it is always drawn at the center of the screen.
Any ideas what I might be doing wrong?

Hi!

Thanks for reporting the issue and sorry for the problem, this will be fixed for next release.

This is the correct code:

Code:

void ImageAtlas::draw(Int part_index, C Vec2 &pos, Flt pixel_size)C

{

   if(InRange(part_index, parts))

   {

    C Part &part=parts[part_index];

      if(C Image *image=images.addr(part.image_index))

      {

         Rect_LU screen_rect(part.center_offset*pixel_size+pos,  // position

                             part.trimmed_size *pixel_size    ); // size

         if(part.rotated)image->drawPartVertical(screen_rect, part.tex_rect);

         else            image->drawPart        (screen_rect, part.tex_rect);

      }

   }

}
