Heretic2 rebased over Yamagi Quake II Remaster

Customized Quake2 engine with Heretic2 code parts.

Heretic 2 SDK code based on Ht2Toolkit

Updated code based on Heretic 2 Reconstruction Project

Tested with Heretic 2 Loki release.

cleanup code

sed -i 's/[[:blank:]]*$//' */*.{c,h}

Comments:

It's on really initial steps, it could be complied ;-), it runs mostly without crashes. That's all what is good.

Drawbacks:

• code use diffent angles values to quake2
• huge amount of possibly dead code
• broken jumps
• no menu implementations
• no books implementations
• code is little bit mess
• only gl1 has full support render
• soft,gl3,vk render has incorrect angles and no particles

To check:

• color type/paticles,
• ANGLE_1 usage in client code,
• different move code and noclip
• Incorrect 16 bit frame fkag unset,
• MAX_MODELS/MAX_SOUND define hardcode,
• no action on button press.

Minimal file set from Loki release:

Code checked with:

Goals:

• Implement minimal set required for single player,
• Multiplayer game or same protocol is not in priority,
• Raven code should be placed only in src/game or separate repository,
• All other code should be GPL or public domain,
• Minimal set of hacks over quake 2 engine.

Yamagi Quake II Remaster

This is an experimental fork of Yamagi Quake II with ongoing work to add support for Quake II Enhanced aka Q2 Remaster(ed). This enhanced version has a lot non trivial changes, adding support isn't easy and takes time. Feel free to try this code but you mileage may vary.

Have a look at the yquake2 repository for the "normal" Yamagi Quake II: https://github.com/yquake2/yquake2

Alpha windows 64 bit binaries.

State:

• GL1/GL3/GLES3/VK:
  • base1: no known issies
  • base2: no known issies
  • q64/outpost: no known issies
  • mguhub: loaded, sometimes broken logic for surface fall in next maps
• GL4:
  • base1: unchecked
  • base2: unchecked
  • q64/outpost: unchecked
  • mguhub: unchecked
• SOFT:
  • base1: broken wall light
  • base2: broken wall light
  • q64/outpost: no known issies
  • mguhub: broken wall light, sometimes broken logic for surface fall in next maps

Monsters:

• incorrect dead animation for Arachnid,
• broken fire effect for Guardian.

Models support:

Format	Original Game	Frame vertex	Meshes	Comments
mdl	Quake 1	8 bit	Single	Unsupported grouped textures
md2	Quake 2	8 bit	Single
md2	Anachronox	8/10/16 bit	Single	No tagged surfaces, unchecked with game
mdx	Kingpin	8 bit	Many	No sfx support, unchecked with game
fm	Heretic 2	8 bit	Many
dkm	Daikatana DKM1	8 bit	Many	Unchecked with game
dkm	Daikatana DKM2	10 bit	Many	Unchecked with game
md3	Quake 3	16 bit	Many	No tags support
md5	Doom 3/Quake 4	float	Many	Requires md2 for skins

All models support only single texture for all meshes and only up to 255 frames.

Texture support:

Format	Original Game	Comments
wal	Quake 2	8 bit
wal	Daikatana	8 bit
m8	Heretic 2	8 bit
m32	Heretic 2	24 bit
pcx	Quake2	24 bit
tga	Quake2	24 bit
png	retexturing	24 bit
jpg	retexturing	24 bit
bmp	Daikatana	24 bit

Maps support:

Format	Version	Game
IBSP	39	Quake 2 / Anachronox / Kingpin / Heretic 2
IBSP	41	Daikatana
QBSP	39	Quake 2 ReRelease
BSPX	39	Quake 2 ReRelease (Extension to IBSP)

Note:

• SiN Gold has IBSP/41 format but has different size of lump and is unsupported.
• Non Quake 2 maps are limmited mostly view only, and could have issues with tranparency or some animations flags and properties.

Goals (finished):

• BSPX DECOUPLEDLM light map support (base1),
• QBSP map format support (mguhub),
• Use ffmpeg for load any video,
• RoQ and Theora cinematic videos support.
• Cinematic videos support in smk, mpeg, ogv format,
• Daikatana/Heretic 2 map partial format support,
• md5 improve load speed,
• support Anachronox .dat format,
• add debug progress loading code for maps.

Goals (none of it finished):

• Single player support,
• Support effects and additional flags for ReRelease when possible.

Bonus goals:

• Port SiN/Daikatana pack support from pakextract,
• support surface flags and content types for Daikatana, Heretic 2, Anachronox,
• Use shared model cache in client code insted reimplemnet in each render,
• Check load soft colormap as 24bit color,
• Use separete texture hi-color buffer for ui in soft render,
• Convert map surface flag by game type,
• Cleanup function declarations in game save code,
• Use 3 bytes vertex normal,
• Support scalled textures for models and walls in soft render and fix lighting with remastered maps,
• modified ReRelease game code support with removed KEX only related code.

Not a goal:

• multiplayer protocol support with KEX engine,
• support KEX engine features (inventary, compass and so on),
• KEX game library support.

Code tested with such maps.

Yamagi Quake II

Yamagi Quake II is an enhanced client for id Software's Quake II with focus on offline and coop gameplay. Both the gameplay and the graphics are unchanged, but many bugs in the last official release were fixed and some nice to have features like widescreen support and a modern OpenGL 3.2 renderer were added. Unlike most other Quake II source ports Yamagi Quake II is fully 64-bit clean. It works perfectly on modern processors and operating systems. Yamagi Quake II runs on nearly all common platforms; including FreeBSD, Linux, NetBSD, OpenBSD, Windows and macOS (experimental).

This code is built upon Icculus Quake II, which itself is based on Quake II 3.21. Yamagi Quake II is released under the terms of the GPL version 2. See the LICENSE file for further information.
