GameKit: Irrlicht + Bullet + readblend + CMake

Post by erwincoumans »

This alpha version of GameKit can read a .blend file from Blender 3D modeler directly, just drag a .blend over the executable.
It uses a small readblend library that can extract arbitrary information directly from a .blend file. Right now it can extract meshes, camera position, textures and physics/collision detection information. Screenshot of Club Silo running in GameKit is here:

You can download source code and precompiled Windows executable preview here:
http://code.google.com/p/gamekit/downloads/list

It uses Irrlicht 1.5, Bullet Physics SDK 2.74 and readblend. Windows projectfiles are included, as well as CMake build system support for cross-platform building. Currently only Windows and Mac OSX are supported, Linux and iPhone are planned.

Feedback is welcome.
Enjoy,
Erwin

i cant understand it, only your blend files work with this it wont read any of mine from 64 bit linux 2.48 blender. what version were you using ?

running the testreader shows this.
(gdb) bt
#0 0x00000000004078f6 in blend_read ()
#1 0x0000000000400e03 in main ()
(gdb)

to test my blender files out use this blend file



after a bit of putting fprintf's all over the segfault was comming from htere

Code: Select all

 
  fprintf(stderr, "reading the STRC table\n");
 
  MY_SEEK(file, strc_offs);
 
  {
 
    int i,j;
 
    for (i=0; i<strc_ents; ++i) {
 
      unsigned short struc_type_index, num_fields;
 
      struc_type_index = read_ushort(file);
 
      num_fields = read_ushort(file);
 
      bf->types[struc_type_index].is_struct = 1;
 
      EXPANDO(bf->strc_indices, struc_type_index);
 
      /*dprintf(stderr, "\n%s: ", bf->types[struc_type_index].name); */
 
      for (j=0; j<num_fields; ++j) {
 
    unsigned short ftype = read_ushort(file);
 
    unsigned short fname = read_ushort(file);
 
    EXPANDO(bf->types[struc_type_index].fieldtypes, ftype);
 
    EXPANDO(bf->types[struc_type_index].fieldnames, fname);
 
    /*dprintf(stderr, "%s %s ,  ", bf->types[ftype].name, bf->names[fname]); */
 
      }
 
    }
 
  }
 
it seems to work good till it hits GPdata
after commenting out dprintf i get

bGPdata: ListBase layers , int flag , short sbuffer_size , short sbuffer_sflag , void *sbuffer , Segmentation fault

It is easy to make it work: just load the 64-bit/big-endian .blend file in a Blender version running on 32-bit little-endian system and save it again. If anyone has a patch to directly read 64-bit/big-endian .blend files, please share it on http://code.google.com/p/gamekit/issues/list

Hope this helps,
Erwin
