DeleD Community Edition

[vgo]

I'm participating in the PGD 2007 Multiplexity game development competition. The idea in the competition is to make a game that combines 2 or more game genres, the entries have to be programmed in Pascal language (Delphi, FreePascal etc.).

My entry for the competition is titled Space Commando and it's a mixture of space sim and first person shooter. The players will be able to fly in space, dock with space stations and walk around inside them.

More information about the competition can be found here
BTW. Delgine seems to be one of the sponsors for the competition.

Yes, we are one of the sponsors indeed.

Goodluck with the compo!

I've been working on my entry for some time and I'm making good progress on the game engine.

The problem I have is that I can't make any models besides some boxes and such, even if I could I don't have the time to do all that myself. I have a friend who's been helping me by making some models, but he is too busy with other stuff aswell.

If anyone could spare some models or make some for me I'd be grateful, naturally if we get things working you'd get your share of the prize too (in the case that we win, of course).

You can get the current build here. There's not much game in it yet, but hopefully that'll change soon enough.

I've been writing import code for the new DXS format and I've ran into some stupid problems.

First, I need the vertices in counter-clockwise order, not in clockwise which seems to be used by DeleD. Second, I need my texture coordinates certain order: (top-left = 0, 1 -> bottom right = 1, 0) DeleD seems to store them so that 0,0 is top left and 1,1 is bottom right.

Vertices are easy to reverse to get the right winding, but what about the texture coordinates? How can I easily "flip" these? If I just reverse them, or try to assign them to the vertices in different order doesn't make any difference because the v coordinate is wrong. How to get the v coordinate to go from up-down to down-up while not skewing the coordinates?

Multiplying the v coordinate with -1 works for some, but if there's coordinates that are from 0 to 1 then I'd need to check for these and reverse them one by one. Is there another way to do this?

EDIT: I just noticed another problem, some of the faces are not visible ie. they face the opposite direction as they should! All these faces seem to be result of CSG operations, so it's not a bug in my code (I hope). How can I fix these?

The vertices and uv-coordinates are compatible with a clockwise winding in an OpenGL-style coordinate system. For any other system, you'll indeed need to do some fiddling.
