I have recently been working on a new tutorial for Dark GDK. The aim of this tutorial is to show some advanced techniques in Dark GDK, specifically loading custom media. The tutorial will guide you through the stages involved in creating new objects and setting their data. The end result is a model from World of Warcraft loaded and animating in Dark GDK. Unfortunately I cannot give out any media for this but the key thing here is the techniques being demonstrated.

Nice tutorial Mike, this will come in handy for a map editor I'm working on.

Is this also possible in .NET version? Or only in the new GDK?

Woah, that's SOOOOO cool!!

Can it be used for any game? I really want to load some other model types to see what happens

This could be useful for remakes and the like.

You can import pretty much any file format you like. Just follow the techniques used here and I'm sure it will work out fine.

@Niels: There are some missing commands in DGDK.NET so it's not possible by now, but I've been talking with APEX for them to be included in future releases.

This one's really nice. I always wanted a Milkshape3D loader, so I'll wait for pex to implement the missing methods and I'd probably try it out.

@Mike: Before I forget as it got to my mind now... Did Paul talk to you about loading from streams? I mean, a lot of people here have been asking this, because DGDK only allows objects/sounds/etc. to be loaded from files, but not streams (not a real way to make PAK files, or anything similar). I've done it "fakely" in LightEngine, by extracting to a temp folder and loading the file, but no the solution most of us expected.

kBessa,

Could you not just create a memblock and read the data from the stream into it, then use the Make [INSERT TYPE HERE] FromMemblock.

kBessa, loading files in this way will be a good thing. It's something we need to consider for an upgrade.

@monotonic: Yep, it's possible for somethings. But what about animated objects? Also, it still would be slower.

@Mike: I'm looking forward to it!

HHey mike you think you could make a tutorial on writing your own format and the loading it? cause i want to write my own but i can't seem to do it and have no idea what to start

I've not looked at this too closely yet - I've been kindly pointed over here from another thread. Mike, once loaded into the executables memory,(and if there was a SAVE OBJECT command in the Dark GDK), could the memory be saved back out as DBO file for example or used with the Enhance Animations plugin? (I guess my question is; does the object exist inside the program the same way as a directX file loaded with LOAD OBJECT?)

good day,

i have a problem loading the materials of my model (now in .x file) that was exported from maya (.mb), the materials and shadings are not loaded, here's a screenshot




when i open the file in dx viewer, the "Blinn" materials are loaded and the shadings are shown, but i get this message

'polySurfaceShapexx_Mesh' material 9 - No effect instance specified.
Reverting to the default effect.

is there a code that would load the materials and shadings?

I didn't completely read through the paper.

How is the animation done in the end? Are the vertices updated manually each frame?

Hi.
When i tried to load the solution files in Visual C++ 2008 Express, I got heaps of compiler errors. Is there something ive gotta do to Visual Studio C++?

If it can be missunderstood or messed up i can stuff it up even more!

I believe you will need to download and install "MPQLib"(library for working with MPQ files) and "ZLib"(a data compression library) from the internet where they are freely available and point your compiler to where they are installed if it doesnt already, to be able to compile and run the code in these tutorials.. It is mentioned in the tutorial PDF somewhere I think, that the code uses functions from those 2 libraries and that they are freely avaiable on the web..

If it ain't broke.... DONT FIX IT !!!

Job well done Mike Johnson!

Nice and clean Tutorial!

This is awesome and very helpful, exactly what i need for my project

I've been working my way through the tutorial and i'm at ms 004 right now, and there seems to be some fundamental problem in the code that i cant figure out, with the following code apparently



It's something i get pointed to when debugging the program, if i dont debug it, if i just run it like normal it stays black and crashes.

when i debug it gives me this error and points to the final bracket in that code listed above: Unhandled exception at 0x004ca87d in Wow Loader.exe: 0xC0000005: Access violation reading location 0x0f958964.

I'm pretty much stuck at this point. I've installed the mpg and z libraries in hopes that maybe missing those would cause a problem, and it did nothing. Has anyone been able to successfully follow this tutorial? Normally when I program i'd be able to ad lib some code to help fix it, but i havent been using cpp long enough to do that.

EDIT:
okay so i figured it might be the model causing the problem so i loaded up a different model, this time a cat, and it worked perfectly, i loaded up a gate, just a static level mesh, and it worked, i opened a dragon and it crashed, an orc and it crashed, wtf? is it possibly something to do with different types of m2 formats?

Does this still work in the newer versions of DGDK?

Cause I can't get it to work, will post some source code when I get home.

Keep it simple.
