GameKit: Irrlicht + Bullet + readblend + CMake

Latest GameKit trunk revision 53 uses Irrlicht 1.6, adds preliminary support to extract rigid body constraints from the .blend file.

Also the Mac OSX build has been fixed, by adding bundle/NIB support in the CMake build system.

here is a CB project that goes in the gamekit directory for WINERS and LINERS (win/Lin)

http://www.mediafire.com/?sharekey=7322 ... f6e8ebb871

oh also something like this should be on line 90 of main.cpp

Code: Select all

    char* fileName;
    if (argv[1])
    fileName = argv[1];
    else
    fileName = "PhysicsAnimationBakingDemo.blend";

Thanks for the contribution, but GameKit revision 64 using cmake 2.6 or later should be able to generate CB projectfiles, have you tried it?
Make sure to add C:\Program Files\CodeBlocks\MinGW\bin or C:\Program Files (x86)\CodeBlocks\MinGW\bin to your PATH.

Code: Select all

cmake . -G "CodeBlocks - MinGW Makefiles"
or
cmake . -G "CodeBlocks - Unix Makefiles"

Thanks,
Erwin

Latest SVN revision 100+ uses an improved .blend parsing library called bParse. It can handle 32/64bit blend files, and little/big endian. Also it is much more convenient to extract any information from the .blend

The loading speed of .blend files is very fast, if the version/bits/endianness matches. So it is a good alternative to exporting data to Irrlicht using Blender python scripts.

Cheers,
Erwin

you mega pwn, i'll release some maps i converted soon packed with texties.

///todo: fix ptr issue
BlendBlock * curveblockptr = blend_block_from_blendpointer(bf, (uint32_t)ptr);

i changed this to uint64_t and it compiled but gave segfault same for you too ?

You need to use bParse for 64bit/big endiab support. You are using the deprecated 'readblend'.

Please check the latest GameKit demo.
Cheers,
Erwin

when i run it without TEST_ECHO_BLEND_READER 1 defined it loads all the blends you supplied nicely. but I gdb'd the segfault with it enabled and got

dna not matching...

It should work with the supplied .blend files with TEST_ECHO_BLEND_READER enabled. Can you confirm?

Your output is missing debug symbols, and the DNA seems to be not matching. Can you report an issue here:
http://code.google.com/p/gamekit/issues/list
make sure to leave TEST_ECHO_BLEND_READER enabled, and include the following info:

gamekit SVN revision (make sure to test latest, 101 currently)
name of the .blend file and if it is not one of the included .blend files a link where to get it
platform details (OS, #bits, endianness) where you got the crash
callstack with debug symbols (-g -O0)

Thanks for the report,
Erwin

posted it for you with the blend file

sorry for the delay.

Thanks for the report, 64bit support of bParse should be fixed now.
(comment/fix the pointer issue in obsolete readblend for now)

Note that using .blend files generated using a 64bit Blender 2.49b will load fastest using a 64bit builds of gamekit/bParse. (and 32bit .blends generated using 32bit Blender 2.49b load fastest in a 32bit gamekit/bParse build).

Can you check revision 105 of gamekit?

aweeee yeaaaaa!!! you put the rock into roll for me! for what its worth i love you do this!

there is a bug where only one mesh can have one texture.

unsigned char DNAstr64[]= {
to just regular char compiles otherwise it says error narrowing conversion from int to unsigned char -Wno-narrowing fixed it but still crashes must be the newer bullet or newer irrlicht ? hmm

was able to get it working by commenting out

// createParentChildHierarchy();

// convertConstraints();

in bulletblendreadernew but im not sure if thats the proper fix

i wonder how to update it to new blender eventually. or is it for 2.49 only ?
