Hiya

Stumbled upon Elimination today, thought nobody was going to use the Gemini source code. Glad so see somebody decided life wasn't gonna get any better I haven't touched z80 since Gemini, the first TI83 infinite plane demo (I see there's a Zero-Wing thing going on, goodie) and some hopeless excursions in 6 DOF 3D culling. Still, would be glad to help if there are any questions about the Gemini code. Tried to post in that sub-topic, but wasn't allowed to so I'll just copy-paste my post here.

Few things about me for those who haven't met me (I do not recognize many of the nicks around here): I'm cynical, glad to offer constructive criticism but I hardly ever pat people on the back unless they're about to pass. So let me get this over with: Looks nice. From now on I'll run in cold mode.

Skimmed through some topics, I do agree that far away sprites look a bit blocky compared even to the ancient Gemini. Remember to design levels taking into account the crappy resolution of the TI84, long distance encounters need some space. I hardly ever did, in fact I never even played through map 3 in Gemini IIRC, but I figured after I had released the game. Turned out alright.
It seems you have a way to store loads more data on the calc than Gemini ever did, so I would suggest mipmapping for all sprites. Use pixel-wide details, select a mipmap by the projected screen size and only ever scale up, never down except maybe beyond the smallest mipmap. If you go for 32x32, 16x16, 8x8, the scaling-code should be fairly trivial to update.
The perspective projection looks very harsh now that you have the caster fullscreen, I would suggest generating new perspective LUTs to get larger walls for a longer distance. I don't remember if I used "f * x / z" of "f * x / (z + z0)" with z0 being a hand-adjusted parameter. Try the latter option and play around with z0 to get a "beefier" perspective projection.
The gun perspective looks odd in fullscreen. Don't settle for a Doom approach, they did that back in '93, just do it right.
I remember there was a bug with the hit detection in Gemini, which was the bug that was mentioned in the dev docs in the Gemini zip. Did anybody find this and fix it?
Personally I think the background esp. on level 17 looks terrible Your decision entirely and if people want it, by all means go for it. I seriously thought you had introduced a bug in the graphics code when I saw that vid on yt...

I may not be super-responsive, but ask questions or whatever and I'll try to answer them in due time. Try PMs if I go silent.

welcome! hope you enjoy your stay!

Heya and welcome here. I do remember you from the old and new MaxCoderz boards as well as Revsoft (I believe you were part of Drubu too, right?). Nice to see some old faces around again. Also I played Gemini a lot in the past back and enjoyed it a lot. My only issue was the RAM requirements (someone discussed updating the game to be split in two files like Desolate with one remaining archived a few years ago, but I never heard again about it) and the random crashes on exit, but otherwise it was one of my favorite ASM games for the 83+ series.

By the way since you stopped calc programming a long while ago, what have you been working on in recent years? Also didn't you also create music in the past? I remember going on your personal website back then until it became a porn site, but it was so long ago that I don't remember.

That is strange, maybe there are permission issues for new members for that sub-forum or it was due to spam a few months ago. I reported it to an admin on Facebook and hopefully it should be fixed now so you can repost your comment there. (Hot Dog never checks the Introduction section, so he will most likely never notice your criticism otherwise )

Actually there is still Chickendude and tr1p1ea passing by from time to time, but they're more active on MaxCoderz and Revsoft respectively. I used to be Kevin (not Rezek/KevinJB) then xlibman then later DJ Omnimaga until I stopped running this site. Besides that there is Lionel Debroux and ExtendeD, but I doubt you ever met them before because they were mostly TI-89/92+/v200 programmers before switching to TI-Nspire. As for criticism you are welcome to provide some to people around here to help them improve. Just make sure to do it politely and in non-biased ways lol (since Omnimaga team tends to primarily focus on community friendliness and avoid language/OS/browser wars)

Yeah, the peanuts. That's the Omnimaga way of welcoming new users
