Help in Programming

[ygor]

I'm a mechanical/aeronautical engineer, my work deals with Frequency Response/Signal Processing/Turbulence Loads. I also enjoy free body mechanics, mathematics and other stuff.

I know C/C++/Matlab/Fortran etc etc and if the team needs, I can give some help in whatever needed!

I also enjoy psycology, so I would like to help with AI programming too (physics is default).

 

I did play all thiefs until now, and I expected more from Deadly Shadows. I hope this mod can bring the same sensation I had with the Dark Project. Hope I can help with something!

Hooray! Someone to help me with rope physics!

We can definitely use help at this point, and that sounds like a useful set of skills. The Doom3 SDK is written in C++. As a first step, you might want to follow the guide to installing and compiling the SDK in the mod programming subsection of the www.doom3world.org forum.

 

We have a few remaining physics bugs that could use some attention. Doom3 physics was written with collision events in mind, and kind of threw force dynamics out the window (for example, it doesn't evaluate the weight force of a heavy object resting on a cantilever, just the impulse from the weight initially colliding with the cantilever. So if you set the weight down really slowly and let go, the cantilever won't tip over). We're probably never going to get a perfect dynamics simulation, but if we can sweep some of the more glaring errors under the rug somehow, that would be a big improvement.

Nice!

 

I will be watching this SDK guide and put things operational here.

 

I had some ideias for those 2 problems, but I need to see how everything is fit together in game engine. I will reply as soon as possible!

Okay, great. I'm unfortunately not going to be around much in the next week, will be out of town at a conference. If you have questions though, feel free to post here and I or one of the other programmers will get back to you when we can. Compiling the SDK is a good first step, then we can identify some self-contained tasks you can help out with.

It was straightforward to compile the SDK... I think the problems will arise when it's to test ingame functions/create a sandbox map.

 

Also, havent you tried to build a cantilever element/rope using physics_AF, physics_RigidBody, Force_spring? I have a first impression that with these elements we can build a lot of gadgets (Since I was not able yet to build something ingame, its just a feeling).

Just keep in mind that Doom 3 physics depends on collisions and impulses; It can't use mass for calculations like HaVoK does.

Weirdo! (Just kidding, welcome aboard

We could definitely need some help with building basic gadgets (although they involve AF bodies and I believe thus support from a modeller), but we also have a lot physics bugs, like two moveable objects blocking a mover (aka door) completely (because collisions with movers are somewhat faked, teleporting the colliding object around instead of just applying an impulse correctly), as well as every object being basically "unbreakable" (so an arrow blocks a door, too).
