Quake 3 on Classic

[Cowcat]

Some stuff to try for those with bigger ppc cpus + 256mg ram:

This is an attempt to recreate Q3 with the old minigl, although it works "mostly" with my Morphed machine.

Hedeon and grelbfarlk tested early versions and told me about problems with audio ahi with 8 bits that lead to crashes, so it's disabled by default. Can be enabled with "s_initsound" "snd_restart" plus if you use 8 bits "sndbits 8" (console or q3config.cfg)

It is in alpha state: If you are lucky enough to run it, only the free demos work: Going to the full game it stays for ever with the dreaded "awaiting snapshot". Cinema support doesn't work so it's off by now.

Works with the demo packs also.

In some systems/sometimes just when starting it stays in "zombie" state (maybe a socket issue ) but finally runs.

Sources will be soon uploaded.

Absolutely incredible!

Hmmm, I just keep getting an error saying "you need to install Quake III in order to play"

This is with both the Q3 Demo and the full install baseq3 directory taken from a pc.

Any ideas what I'm doing wrong?

[grelbfarlk]

Ah finally NDA lifted I have to upload my video...

"you need to install Quake III in order to play"

It is imperative to have nothing else than baseq3 dir with the paks: No config, no qkey...etc.

Ah finally NDA lifted

Oh !! forgot to tell... .


There are important sets on q3config.cfg once it's created from game, and dozens of vars to toggle: Some of them are disabled by default or non-functional like changing "primitives" drawing that is now hardcoded on "3".

Of course it's very heavy on calculations. Look out for a Sonnet G4

[trixster]

ok, i'm up and running. I had to copy across my morphos install onto the A4000.

Wohoo, what an achievement cowcat, amazing work!

Here's a very quick video, default settings:

Thanks trixter !!
I had no idea of what could be the result on real Amigas.
From the video it looks awesome

By the way I realized now that multiplayer option is not working, and was working before that version ....oh well.

[trixster]

It is awesome. I'm surprised it runs so quickly.

Now it's time to try sound and some config tweaks.

[grelbfarlk]

Seems like it has improved since Alpha 4, with that version I turned the gfx options way down to get 29FPS at 640x480.

Seems like it has improved since Alpha 4

There are some endian inlines in some places also take a look at this code used on original Q3 sources:

        
	width = xmax - xmin;
	height = ymax - ymin;
	
	dest->projectionMatrix[0] = 2 * zProj / width;
	dest->projectionMatrix[4] = 0;
	dest->projectionMatrix[8] = (xmax + xmin + 2 * stereoSep) / width;
	dest->projectionMatrix[12] = 2 * zProj * stereoSep / width;

	dest->projectionMatrix[1] = 0;
	dest->projectionMatrix[5] = 2 * zProj / height;
	dest->projectionMatrix[9] = ( ymax + ymin ) / height;	// normally 0
	dest->projectionMatrix[13] = 0;

Now my version:

	width = 1.0f / (xmax - xmin);
	height = 1.0f / (ymax - ymin);
	
	dest->projectionMatrix[0] = 2 * zProj * width;
	dest->projectionMatrix[4] = 0;
	dest->projectionMatrix[8] = (xmax + xmin + 2 * stereoSep) * width;
	dest->projectionMatrix[12] = 2 * zProj * stereoSep * width;

	dest->projectionMatrix[1] = 0;
	dest->projectionMatrix[5] = 2 * zProj * height;
	dest->projectionMatrix[9] = ( ymax + ymin ) * height;	// normally 0
	dest->projectionMatrix[13] = 0;

Half of this stuff is how minigl does things for projections, but Q3 bypasses opengl functions by doing it his own way. I don't claim this to be the result of the increased speed but even the "inexact" calculations by saving divisions, it seems to work (besides other faster calculations in other places).

Gibberish for people, but this is Coders thread

[Sir_Lucas]

WoW!! Well done!! Great job!!

[Sinphaltimus]

This is utterly astounding.

[Marlon_]

Awesome! I'm glad you're releasing the sources. Will it be put on github or something like that?

[nexus]

woot

[jack-3d]

The best Christmas present we could ever get!!! You are the best! Downloading...

[trixster]

We need some vids from people with G3 500 and G4 ppc. And some csppc and cvisionppc

[Cowcat]

Sources will be uploaded here as I always do and a new version with the multiplayer side working. Hope to find soon where is the problem.

No vm ppc bytecode, no dlls, etc....too complicated now.

I have a 68k version but doesn't work right now at the time to load scenes.

There are some issues with one of the levels I played (demo/full game) that crash the game at random times. Only once I could complete it: "Q3DM7".

About sound I don't know: I tried some stuff from Q2, forced the engine to use 8 bits sampling, even forced AHI code to run only with 8 bit, but didn't see any particular issue with MOS besides non-working, noise or OK. No crash there.


Thanks for your words guys

Waiting my kids and wife goes sleep, then I will try on CSPPC+CVPPC and also on Sonnets (500, 400/1, 400/512).

Why not publish it on a public version system so others can contribute? Would it be okay for someone else to put it on github?

[Hedeon]

What are the settings for 29'fps?
