There's nothing new or different that you need to have in the Level Header. For Mario Kart's typeoflevel, it needs Single Player, Race, and of course, Mario. And even if it did, I would do it myself once I get the level.
Here's the Riders news:
All music OGGs have had their filesize reduced, and now loop continuously.
If you are already playing a game, and try to enter Time Attack, you get the "You are already playing" message. Mostly for people who went there while hosting/joining a netgame.
The "Switch Map..." menu got into the code while it was on the SVN, it simply didn't work. Until now, I got it working again.
Jet now has his goggles on, is holding his Extreme gear, and is standing, walking, and running with it. I only need to make the Trick frames, and he's done. I can still try to make every Speed character have their grinding animation, and give Knuckles and Eggman the punching animation, but I'm too lazy.
On an small note, I finally organized all of the player's frames. The Walking frames are now from B to I, Trick frames are from T to Z and [, and other stuff like that. I didn't remove any frames, but I'm thinking of adding 2 more for Mario Kart mode. No point in having 1 set of frames for a whole wad file. It's going to use the "c" and "d" frames, I'm strongly guessing.
I also tried to add the 3D to 2D mode to the riders code, and after 10 minutes, it didn't work. I compiled the original code to test it out, and it didn't work either. Probably because it has #ifdef SRB2TODO on it, I don't know. Then I reminded myself that I tried manually before, by using "twodlevel = true;". It affected everybody, though. Well it didn't work this time, and I figured it must of been because it was placed in the wrong section. It's originally in P_ProcessLineSpecial, and the section that worked was in P_ProcessSpecialSector. I tried it out, and I got it working for individual players. Anyways, this is just a hint on what to expect in SRB2 Illusion.
Finally, yeah, I'm just about done. I just need to finish Jet's trick frames, make 3 levels, and finish up the Credits cutscene. I already have SRB2 Illusion drawn here, and I'm drawing Sky Road right now. We'll see if I can finish this before the weekend is over. I might go to NY and MA this weekend, but there's a 50% chance I will. If I do, it'll have to be finished sometime NEXT week.
