Turns out I had the old Blender files on my backup hard drive after all, so I thought I'd give it another go, since I hate the fact that it seemed like such a shoddy add-on, what with the z-fighting making it flicker in and out of existence like a spastic hologram.
I've essentially fixed that problem by deleting some faces on the model, and now it's entirely gone, except for at a few angles in the "cockpit" view, which I've placed inside the colony to give an interior panorama. If you keep the view steady, it doesn't flicker at all, and if you look around, it only flickers a tiny bit in a few places. Hardly noticeable at all. I've improved the mesh a little bit as well, adding "hinges" on the mirrors, and bridges across the windows between the various land areas. Also fixed a few normals that were reversed, but you could hardly see them anyway.
I've also added UMMU capability, but so far have not been able to add the capability to switch active docks, which is something this requires, of course, or add the ability to add crew while the sim is running. I copied all the code from the SDK readmes and examples, but it won't compile, citing various problems with the word "UMmuCrewAddCallback" involving "bool"s and a bunch of "*"s that make absolutely no sense to me. My compiler was saying "use &oneill::UMmuCrewAddCallback" but I've never been able to find a satisfactory explanation of what an "&" means to C++ or where I should put said character, and my trial and error method was getting me nowhere.
So I'm asking for help; here's the entire code for the colony, with the problem sections removed - This is the latest code I have that works:
Code:
// ==============================================================
//O'Neill Colony Source Code
//Taken from the Shuttle PB - I didn't want to mess with anything I didn't have to, so there's
//a lot of meaningless data left over, but hopefully it won't be an issue.

#define ORBITER_MODULE
#include "orbitersdk.h"
#include "math.h"

// ==============================================================
// Calculate lift coefficient [Cl] as a function of aoa (angle of attack) over -Pi ... Pi
// Implemented here as a piecewise linear function
// When are you gonna have this thing in an atmosphere? Maybe you could drop it onto a city.
// I dunno, I'm just worried cutting this code will mess things up somehow.
// Adding seemingly unrelated things has all sorts of unanticipated effects in the sim.
double LiftCoeff (double aoa)
{
const int nlift = 9;
static const double AOA[nlift] = {-180*RAD,-60*RAD,-30*RAD,-1*RAD,15*RAD,20*RAD,25*RAD,60*RAD,180*RAD};
static const double CL[nlift] = { 0, 0, -0.1, 0, 0.2, 0.25, 0.2, 0, 0};
static const double SCL[nlift] = {(CL[1]-CL[0])/(AOA[1]-AOA[0]), (CL[2]-CL[1])/(AOA[2]-AOA[1]),
(CL[3]-CL[2])/(AOA[3]-AOA[2]), (CL[4]-CL[3])/(AOA[4]-AOA[3]),

}THINGS LEFT TO DO:
- Add multiple UMMU docks
- Add the ability to add new crew while Orbiter is still running
- Tweak the textures for the new mesh (this I can do easily on my own)
- Figure out a value for "SetVisibilityLimit" so that the colony appears as a white dot from far away, instead of suddenly appearing as a mesh a few thousand km away. I have tried everything I can think of and nothing seems to work.
- Add beacons; if someone can give me the code for a stationary one and a rotating one, I can place the rest myself.
- Add RCS and main engines. I'm pretty sure I can do that myself, and someone might want to mess around with them. I think I remember someone mentioning it in the old thread.
That's all I can think of... I was wondering about adding UCGO as well, since there's a line of white squares on the right side of the dock texture that's believable as some kind of cargo attachment area, but one thing at a time, I guess.
If someone could help me with this code, I'd be extremely grateful - It's entirely beyond my skill level and makes no sense to me. None of the tutorials are thorough enough, and the API documents don't have any context for the layperson.
If anyone is willing to talk me through this or, wonder of wonders, put the code in themselves, I will happily return the favor with a textured mesh or a drawing or some other item that falls more within my skillset.
