About Prey(2006)

For playing Prey(2006)(jmarshall 's PreyDoom). Now can play all levels, but some levels has bugs.

Putting PC Prey game data file to preybase folder and START directly.

Some problems solution: e.g. using cvar harm_ui_translateAlienFont to translate Alien text on GUI.

Exists bugs: e.g. some incorrect collision(using noclip), some GUIs not work(Music CD in RoadHouse).

If settings UI is not work, can edit preyconfig.cfg for binding extras key.

bind "Your key of spirit walk" "_impulse54"

bind "Your key of second mode attack of weapons" "_attackAlt"

bind "Your key of toggle lighter" "_impulse16"

bind "Your key of drop" "_impulse25"

About Quake IV

For playing Quake 4(jmarshall 's Quake4Doom). Now can play all levels, but some levels has bugs.

Putting PC Quake 4 game data file to q4base folder and START directly.

Suggest to extract Quake 4 patch resource to q4base game data folder first(in menu Other -> Extract resource).

SABot a9 mod multiplayer-game map aas files and bot scripts(for bots in multiplayer-game).

Problems and resolutions

Particle system: Now is not work(Quake4 using new advanced BSE particle system, it not open-source, jmarshall has realized and added by decompiling ETQW's BSE binary file, also see jmarshall23/Quake4BSE), but it not work yet. Now implementing a OpenBSE with DOOM3 original FX/Particle system, some effects can played, but has incorrect render.

Entity render: Some game entities render incorrect.

Bot mod

Added SABot a7 mod support.

Extract q4base/sabot_a9.pk4 file in apk to Quake4 game data folder, it includes some defs, scripts and MP game map AAS file.

Set cvar harm_g_autoGenAASFileInMPGame to 1 for generating a bad AAS file when loading map in Multiplayer-Game and not valid AAS file in current map, you can also put your MP map's AAS file to maps/mp folder(botaas32).

Set harm_si_autoFillBots to 1 for automatic fill bots when start MP game.

Execute addbots for add multiplayer bot.

Execute fillbots for auto fill multiplayer bots.

Change logs

Build:

idTech4A++ using std libc's malloc/free in Mem_Alloc/Mem_Free in idlib/Heap.cpp
idTech4A++ force using generic SIMD, not compile all SIMD of processor in all platform(TODO: enable them on windows/Linux)

Engine

_MULTITHREAD: Add multithread support for rendering.

_USING_STB: Using stb header for jpeg/png/dds texture image and jpeg/png/bmp/dds screenshot support.

_K_CLANG: If compiling by clang not GCC.

_MODEL_OBJ: Add obj static model support.

_MODEL_DAE: Add dae static model support.

_SHADOW_MAPPING: Add Shadow mapping support.

_OPENGLES3: Add OpenGLES3.0 support.

_OPENAL _OPENAL_EFX _OPENAL_SOFT: Add OpenAL(soft) and EFX Reverb support.

_NO_LIGHT: Add no lighting support.

_STENCIL_SHADOW_IMPROVE: Add stencil shadow improve support(translucent shadow, force combine global shadow and self local shadow).

_SOFT_STENCIL_SHADOW: soft shadow(OpenGLES3.1+), must defined _STENCIL_SHADOW_IMPROVE first.

_MINIZ: Using miniz instead of zlib, using minizip instead of DOOM3's UnZip(Disabled).

_USING_STB_OGG: Using stb_vorbis instead of libogg and libvorbis(Disabled).

If want to port `Quake4` or `Prey(2006)` to PC or other platform of based on `DOOM3` engine open-source version, because DIII4A based on Android platform and OpenGLES, so has some differences with original version. But I mark some macros in source as patches at all changes, although must find these macros in source code and manual use these patches.

And for keeping original DOOM3 source file structures, for all new source files, I put them on a new folder, and in these folder has same directory structure with DOOM3(e.g. framework, renderer, idlib...).

Quake 4

`_RAVEN`, `_QUAKE4` is patches macros, find them in `DIII4A` source code.

All new sources files put on `raven` folder.

_RAVEN: for compile core engine (DOOM3 source code) and idlib (DOOM3 source code).

_QUAKE4: for compile game (Q4SDK source code) library.

Build core engine: define macro _RAVEN, _RAVEN_FX(OpenBSE if need, unnecessary)

Build game library: define macro _RAVEN, _QUAKE4
About BSE

Because BSE not open-source, so I default supply a NULL implement and a uncompleted but working implement with DOOM3 Particle/Fx system(using macros _RAVEN_FX marked).

About BOT

Define macro MOD_BOTS will compile SABot a7(from DOOM3) mod source code for bot support in multiplayer-game.

About Full body awareness support

Define macro _MOD_FULL_BODY_AWARENESS will compile Full-body-awareness support.

Prey(2006)

`_HUMANHEAD`, `_PREY` is patches macros, find them in `DIII4A` source code.

All new sources files put on `humanhead` folder.

_HUMANHEAD: for compile core engine (DOOM3 source code) and idlib (DOOM3 source code).

_PREY: for compile game (PreySDK source code) library.

Build core engine: define macro _HUMANHEAD

Build game library: define macro _HUMANHEAD, _PREY, and original SDK macros HUMANHEAD
About Full body awareness support

Define macro _MOD_FULL_BODY_AWARENESS will compile Full-body-awareness support.

Android

Define macro `ANDROID`.

_OPENSLES: Add OpenSLES support for sound.

Linux
