This is pretty cool! I thoguht it was going to be grayscale...

In the docs, Adamman said he plans to put greyscale in the final version. Previous attempts at greyscale on the 82 have pretty flickery, but hopefully he can figure something out.

Defiance is amazing!

Looks like a cool game.

I'd just like to get this out before people start commenting:
I have an 86, and I will probably try to port it myself to this calculator. For other calculators, you can email me with requests to port it AFTER the final version is released.
Thank you,

~Adamman

Hmm, never say that you're going to do something until you've already done it :) You'll recieve a ton of email about it now.

Go ahead and do it anyway.

Just a question with the game(or demo, it doesn't really matter here):

I know that it claims a 3D engine, but since I can't clearly find out if the game works this way---Is the movement smoot like a Doom game or is it based more like the BASIC versions of Doom where you take one slow step at a time. In other words, if I hold down the up button, will the walls scroll by at the speed which I am moving, or will I see them move by chunk by chunk? If the former, than I must commend the programmer on something I thought was impossible with the lower calcs.

didn't I see an earlier post for this game (that it was in progress) last year?

Take a look at the homepage, it's got a cool animated screenshot. It seems like a cross between wolfenstein and doom (closer to wolf at the moment but with support for non-right angle walls). Now for the full doom effect, it needs sound, music, support for quasi-3d movement, and other stuff.

Anyway, I'm surprised that this doesn't seem to be any less smooth than daedalus on the 85 -- and it's more complicated to boot (but without grayscale, I guess)

Yeah, there were actually two posts, one announcing the development (sometime in october or november I think) and one with screenshots (I believe January)

I think this is, to quote Martha Stewart, "a very good thing." First of all, Adamman has considerably renewed life in the TI-82 area...now all you 82 owners actually have something to look forward to! Second, this could end up being one of the most impressive calculator games of all time...I'm impressed that Adamman is attempting to do so much with a game on such a low calc model - namely GRAYSCALE! (never underestimate the power of an 82!) Finally, I think porting to the 86 is a very good idea...I'm sure the author will find it easier to accomplish this game on that calc model, especially with the increased memory of the 86.

When he's done with the 82 version, I'll have to try it out with YAS, then drool until the 86 version comes out. Ahh...thank you very much for this impressive project Adamman, and the best of luck to you! (can you tell I'm excited about this game? :-)

Oh, yeah, one more thing: I'm sure ticalc.org is working on this, but just in case: the file information link (the purple icon ) next to Defiance under "Recent Additions to Our Archives" is currently broken. Uh...thank you for your time (or something)...

yeah, i noticed that too, but what do ya expect, it's ticalc.org

Now I wish I had an 82!! I'm not asking anyone to port this, but would it be too terribly difficult to port it to the 83? I know the 82/83 are very similar, and BASIC programs are compatible (82 -> 83), but is it the same (or at least similar) with ASM programs?

Well here's the deal with porting...The program has very little 82-specific code, so porting really shouldn't be a big problem. This is why I said I would try it myself.

~Adamman

If you want a Defiance type game, wait for Tuake! You can check out the project at http://z80.us.fornax.com/upcomming.php3 -- it is a very similar game that will probably use greyscale.

Based on the animated screenshot, "Tuake" appears to have "block" movement. The directional indicator at the top of the screen (displays "N" for north, "W" for west, and so on) would seem to support this. Block movement for a first-person game can't really compare to the truer 3-D feeling found in games such as Defiance and Maze 3-D. Granted, grayscale and 2 player mode is nice, but for the time being I'll be watching Defiance more closely.

So, what's the deal with the "Unable to find segment" problem? I tested this demo on CalcEm and got that error 3 times.

Great Program for 12063 bytes! Makes you wonder if the gameboy is better.

Will there ever be switches to make certin walls disappear? Keys?

Until monsters are added, a nice "Race against the clock collecting coins" 3d game would be nice.

There's just some problems with moving between sectors. Some of it is inaccuracy in the program, too.
Yeah, someday I'll make doors that open, but I would like to put in a few extra features (walls that are only partially drawn and you can see through them, an index for where in the texture to start drawing, etc)

~Adamman

Adam, is this a raycasting engine, similar to Andrea Ess's TI-85 game, or is it true 3D? It feels much more 3D than any other game I've tried, including Maze3D (Which uses the same raycasting approach as AE's game).

KnightRT

It's far from true 3d, but it's closer than true raycasting. Think Doom without variable height sectors.

~Adamman

how come you didnt send me an email telling me you realeased it? i have been waiting a year for this :( oh well :)

This looks pretty damn sweet. Too bad I don't have a link cable.
