ObjectGDK is an OOP wrapper for DarkGDK. It wraps all of DarkGDK into about 25 different classes.

You can find ObjectGDK here: http://objectgdk.leadhoster.com/home.html


Here's some example code of spinning a cube in ObjectGDK:



Instructions

Just place the folders wherever you want, then in VC++ Express go to Options->Projects and Solutions->VC++ Directories and set the Include folder of ObjectGDK to the Include directories.

Credits
-jason p sage, who helped me out quite a bit when I started my wrapper.
-WindowsKiller, for pixel-perfect collision code. I haven't actually added it yet, but I figured I'd add this now so I don't forget.

...plus several people/sites for media; you can find a list in the README.

If you guys have any ideas of what else I can add feel free to make suggestions.

Just wanted to bump because I've finished an update. Nothing much, just added the limb functions and added all the memblock functions, and I have working commented examples for both. You can download in my first post. I'm also done with vertexdata functions and almost done with sparky's collision, so you can expect another update tomorrow.

K, I've finished the next update. It includes all the vertexdata and bitmap functions, as well as everything from Sparky's collision. That means that the effect functions are all that's left! You can download v0.3 in the first post.

Basically it'll allow you to use OOP with DarkGDK. However, by the nature of your question I can tell you probably don't know what OOP is. I would explain it to you, but I'm very bad at explaining things. so you can check out this site in order to learn about it. OOP can speed up development time and a lot of people prefer it because they find it easier to use and understand. My OOP wrapper simply allows you to use OOP with DarkGDK. Hope that explained it.

Thanks for the explanation, the problem was that i didn't get it is because i didn't see to much of a diference betwen the OOP code and DarkGDK code in a matter of lines speaking.

I`m downloading now your wrapper to test it out and try to learn it. Thanks again for the wrapper and explanation

Cool! Hope it helps ya. As far as I'm concerned ObjectGDK isn't totally 100% ready to make an entire complex game (i.e. an FPS engine) so it's really important that you point out ANY missing commands or bugs with it so I can get it to that point.

How'd you guess?

I made a very basic game demo just to get a couple interesting screenshots. It's a ball-rolling game where you play the role of a smiley face. I should have v0.4 of ObjectGDK done soon.

v0.4 is done! Download is in my first post. I've added support for DarkPhysics Cloths and Materials. I've also added a couple missing functions here and there.

Version 0.5 is done, I've added the shader/effect functions. It also includes 3 new examples.

Since I'm mostly done with DGDK functions I think I'm gonna start working more on the documentation and the tutorials/examples, so if you guys have any ideas please tell.

Hi!

Thank you for ObjectGDK, good job.

I have one question though. Does IMouseInput::GetMovement() do the same as dbMouseMoveX/Y? When I try to use it I get -1610612736, am I doing something wrong?

Sorry for being a newbie @-@

I've created a small site for ObjectGDK, so rather than update this thread I'm gonna update the site. You can find the site in the first post.

Also I freeze every time I try to use terrain, even in your example

Quote: "First-chance exception at 0x005e599e in Example 9 - Terrain.exe: 0xC0000005: Access violation reading location 0x00000008.
Unhandled exception at 0x005e599e in Example 9 - Terrain.exe: 0xC0000005: Access violation reading location 0x00000008."


It runs but I get an error and am left with a black screen until I end the process.

Sorry Rena, didn't see your posts because you're still on post-approval.

I can't be sure unless you post your code, but my only guess is that you're not using the 'Update()' function in the mouse. Basically, in DarkGDK if you call the 'MouseMoveX()' function more than once in a loop, then you get funky values. So, instead I call
it once in the Update function, and store it in a variable, then just return the variable instead. The reason you're getting a weird number is because dbMouseMoveX() and dbMouseMoveY() haven't been called yet, so you're retrieving uninitialized variables. Just add:



to your main loop. Of course, replace 'Mouse' with your mouse pointer.

I'll investigate that, and edit my post if I find anything. Thanks for using my library , if you find ANY bugs at all I really want to know so I can improve the system.

Thanks, that did it.

Does that happen to you too? Worried it might just be me.

It seems to happen when ITerrain::Build() is called, I get an error message that just says '6' too.

In your 'Water Surfaces' demo the call to SceneDevice::NewWaterSurface() is missing an argument. You didn't mention it in the comments so it was probably added since.

Fixed. Thanks. Also I had changed 'SetControlFPS()' and forgot to change params, so I fixed that one as well.

Is this the example?? And are you running from MSVC++ or building the project then running it outside MSVC++?? The project works fine for me if I compile then run from outside MSVC++. And does this happen with DarkGDK's terrain demo, or only with ObjectGDK??

I didn't think to try that, it runs fine when run outside. Weird.

DarkGDK's Terrain demo runs fine from within MSVC++

Great Work, makes programming in Dark basic a lot easier.

Could you build and compile youre objects so that they can be used as .net objects?

I don't know if this has been asked, but does this do automatic garbage collection? It looks really neat!

Not at the moment, but I'm looking into doing that. I don't know if I've mentioned this yet but I'm still fairly new to C++, so a lot of topics such as garbage collection are pretty advanced to me, and I'm still learning about things like that. But I'll see what I can do sometime in the future.

I've got another update done (0.7, don't ask me why I skipped 0.6 ), but I don't have time to upload tonight so I'll do it tomorrow. List of fixes/added functions:
