3rd Zigock Bot II for Yamagi Quake II

3rd Zigock Bot II for Yamagi Quake II

This is a best effort port of the 3rd Zigock Bot II to Yamagi Quake II. The code is nearly unchanged from the original, just some scary compiler warning were fixes and some hard coded pathes were changed to make use of Yamagi Quake IIs enhanced, unix compatible VFS.

Installation

• Extract the ZIP archive misc/assets.zip to your Quake II directory.
• Build the game.so by calling make and copy it to the 3zb2/ dir.

For more informations refer to the user guide, included with the assets.

3zb2's Issues

[WIP] [Enhancement] Rogue and Zaero support.

At release time, 3zb2 wasn't compatible at all with weapons and items from these two mods. I'm planning on adding this support soon, but I'll need testers.

Build warnings on Debian

Building 3zb2 on Debian 12 there are lots of warnings.
Most of them are easy to remedy:

[  3%] Building C object CMakeFiles/game.dir/src/bot/fire.c.o
/home/arjen/dev/Q2RTX/workingdir/_yquake2/3zb2/src/bot/fire.c: In function ‘B_UseHyperBlaster’:

  539 |  zgcl_t  *zc;
      |           ^~

But this one I don't know how to resolve:

In file included from /home/arjen/dev/Q2RTX/workingdir/_yquake2/3zb2/src/g_ctf.c:1:

I've been searching on stackoverflow.com but couldn't find something that could help in this case.

Anybody has an idea?

Help Needed on Linux

I think I'm close but I'm missing something. I have compiled Yamagi on Linux and I've copied the assets from this repo to 3zb2 folder, I put game.so into that folder also, and I'm running the game w/ this alias:

alias quake2="cd ~/Games/Linux/Quake\ II &&  ./quake2 -datadir ~/Games/Linux/Quake\ II +set game 3zb2 +set deathmatch 1 +disconnect"

The game loads fine, but here are my issues:

• The game doesn't autoexec game.cfg, so I have to do it manually.
• The game doesn't autoexec addbot.cfg, so I have to do it manually.
• When I type addbot it says Add bot 1 but nothing ever happens.
• When I type sv spb 2 it says server command spb not found.

Any help would be appreciated.

How to run with Yamagi Quake2 on Linux?

The user guide contains no information about running this modification though.

-arch i386 should be removed for Darwin

Looks like we need to remove support for i386 architecture for newer OSX versions (ifeq ($(YQ2_OSTYPE), Darwin) case). There should be no "-arch i386" or "make" will fail with:

ld: symbol(s) not found for architecture i386

locating 3ZBConfig.cfg w/ +basedir

I'm trying to run a server on Ubuntu using their quake2-server package (which uses yamagi quake2). I've got 3zb2 installed and the game finds the game.so in /usr/lib/yamagi-quake2/3zb2 and is able to find the pak6.pak in /usr/share/games/quake2/3zb2... but doesn't appear to be able to locate the 3ZBConfig.cfg, routes, etc. even though they are in that same directory. Looking at the source a little, I think this is because the code is simply using fopen with relative paths like 3zb2/3ZBConfig.cfg which aren't guaranteed to be relative to the basedir. I think when the basedir is set, it should probably be using that as the base path to use when opening those files.

CMakeLists.txt tries to build non-existing g_turret.c

The Makefile does not suffer from this and so I think they must have just gone out-of-sync at some point.
