A fresh install of NS comes with updated config files containing everything you need to get playing on the standard settings most players prefer. Customization options are built into the advanced options menu, like the Nine Legends competitive UI option. For further customization, team and weapon specific config files are also now available.
1. If you recieve a "could not load library" error for the client.dll, please install the **[latest Microsoft Visual C++ Redistributable package](https://aka.ms/vs/17/release/vc_redist.x86.exe)**.
1. Make sure you have verified Half-Life's integrity. Click [here](https://support.steampowered.com/kb_article.php?ref=2037-QEUH-3335) for detailed instructions.
1. Make sure you have a clean install. Go to the half-life directory (eg. `c:\Program Files\Steam\steamapps\common\Half-Life`) and remove or rename the ``ns`` folder, then try installing NS.
- You may need to remove or rename the `libstdc++so.6` and possibly the `libgcc.so.1` in the `Half-Life` directory so the linux distro's can be used instead. The one steam provides is outdated.
- 32 bit C libraries might need to be installed. Try `apt-get install libc6-i386` if on debian or ubuntu. The `libm.so.6` from it may need to be placed in your half-life folder if you cannot install that package.
1. Set the HLDS install directory after opening steamcmd and before logging in. The following steps assume a directory named `hlds` from doing `force_install_dir ./hlds/`
1. You'll want to run `app_update 90 validate` multiple times in steamCMD to install HLDS and fully update it, as it won't completely do it the first time.
1. Copy the `ns` directory into the `hlds` directory after installing HLDS from steamcmd
- Remove or rename the `libstdc++so.6` in the `hlds` directory so the linux distro's can be used instead. The one steam provides is outdated. You may need to rename the `libgcc.so.1` file in the same directory as well.
- 32 bit C libraries might need to be installed. Try `apt-get install libc6-i386` if on debian or ubuntu. The libm.so.6 from it may need to be placed in your HLDS folder if you cannot install that package.
If you are behind a NAT(Router) make sure to open at least those ports:
- 27015 UDP (game transmission, pings)
- 26900 UDP (VAC service) -- automatically increments if used in case of additional server processes
For more information see the [HLDS valve wiki](https://developer.valvesoftware.com/wiki/Half-Life_Dedicated_Server).
In order to check if your server is connected to the steam servers copy the following url in your browser and replace `<your IP address>` with your external ip:
`http://api.steampowered.com/ISteamApps/GetServersAtAddress/v0001?addr=<your IP address>&format=json`
There is an updated version of metamod called [metamod-p](https://github.com/APGRoboCop/metamod-p/).
Evobot is integrated in NS 3.3 and can be configured in the listen server creation UI or via the following commands in the `server.cfg` for dedicated servers:
```
mp_botsenabled (0/1) Bots are enabled Y/N
mp_botautomode (0-2) (0 = manually add/remove bots, 1 = Maintain min player counts, 2 = Keep teams balanced only)
mp_botcommandermode (0-2) (0 = Bot never commands, 1 = Bot commands after mp_botcommanderwait seconds if nobody else does, 2 = Bot only commands if no humans are on the team)
mp_botcommanderwait (0..) How long the bot should wait before taking command (if allowed to)
mp_botusemapdefaults (0/1) Use the map min player counts defined in nsbots.ini Y/N
mp_botminplayers (0-32) If not using map defaults, maintain this player population for all maps
mp_botallowlerk (0/1) Bot is allowed to evolve lerk Y/N
mp_botallowfade (0/1) Bot is allowed to evolve fade Y/N
mp_botallowonos (0/1) Bot is allowed to evolve onos Y/N
mp_botlerkcooldown (0..) After a lerk is killed, how long in seconds should the bot wait to evolve again (default 60s)
mp_botmaxstucktime (0..) If a bot is stuck longer than this time (in seconds) it will suicide (default 15s)
mp_botdebugmode (0-2) (0 = Disabled, 1 = Drone Mode, 2 = Test Nav Mode). Use test nav mode to validate your nav files.
sv_botadd <Team> If mp_botautomode is 0, this will manually add a bot to team 1 or 2. If Team is 0, it will assign randomly
sv_botremove <Team> If mp_botautomode is 0, this will manually remove a bot from team 1 or 2. If Team is 0, it will remove randomly
sv_botregenini If your copy of nsbots.ini is lost or corrupted, this will generate a fresh one
bot_cometome If mp_botdebugmode is 1, this will force the bot to come to you. Helps test your nav file.
bot_drawoffmeshconns Will draw the off-mesh connections present in the loaded navigation file, color-coded based on connection type
bot_drawtempobstacles Will draw nearby temporary obstacles affecting the nav mesh
```
The bot system uses a modified version of the Detour library from [recastnavigation](https://github.com/recastnavigation/recastnavigation).
If you get this error when running the app: `Fatal Error - could not load library (client.so)`, With a high chance it is because of some `UNDEFINED SYMBOLS` in the shared library. But you can check this with this command:
Debug builds can be built with the `Debug` build option. The other debug options are currently broken and are a reference from the original UWE source release. After building the debug version and running it, attach the visual studio debugger to hl.exe.
DYLD_LIBRARY_PATH=".:$DYLD_LIBRARY_PATH" /Applications/Xcode.app/Contents/Developer/usr/bin/lldb -- ./hl_osx r -game ns -dev -steam -windowed
```
Have to use XCode's lldb to get around https://stackoverflow.com/a/33589760 (Lack of environment variables). `-windowed` as windowed mode makes it easier to deal with crashes on MacOS.
