Natural Selection v3.2.1a

This is a complete rebuild of the game Natural Selection for Windows and Linux. It includes fixes by fmoraw, Bacsu, puzl and others mostly just to make this source code build and run on all platforms.

Downloads

First you need NS 3.2 full installation. Download from UWE website or from here here

You can find releases here.

Download latest: ns_v321b_patch.zip

Remember to extract them to your Half-Life/ns directory. It should replace the existing files.

Changes

In order to make this game work for linux the old half-life engine files were replaced with the newer ones. In addtion some changes are accounted for the use of an acient glibc library. Some changes to the game itself have been made and these include:

• The ChatPanel has been replaced in favor of the old hl chat.
• The observatory has now a spherical detection like the sensory chamber
• Removed special NS gamma since it is windows only

The plan is to bring the chat and the gamma back when a cross-platfrom solution can be achieved.

Bugs

• Chat input is not visible while spectating
• sg reload bug
• FPS_Effects FPS dependant fire rates and player physics
• gorge's view rotates when he drops a structure from the popup menu?
• The background of text in the menu or in popups does not look nice possible realted to the special ns gamma.
• Flashing available alien upgrade icons (defense, movement and sensory) tend to disappear when a player dies and respawns. The icons won't appear until the alien chooses an upgrade.
• func_train and func_tracktrain entities don't reset to their original positions when a round has ended
• windows server works only with the hlds tool

If you find more please report them!

Compiling

First. you need some libraries. On Ubuntu it is:

apt-get install build-essential git gdb gcc-multilib g++-multilib libc6-i386 libcurl4-openssl-dev:i386 libpng12-dev:i386

For windows compilation should be working if you have VS2010 installed.

Then you will need to get the files:

git clone https://github.com/fmoraw/NS.git

Then to build `` and use make hl_cll for the client and make ns for the server.

cd NS/main/source/linux

For client use make hl_cll and for server use make ns

If you get the 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:

ldd -r -d client.so

Make sure you have vgui.so copied to cl_dll folder too on Linux.

Debugging

If you want to debug:

LD_LIBRARY_PATH=".:$LD_LIBRARY_PATH" gdb ./hl_linux r -game ns -dev -steam

Due to the new engine and the nature of Linux I had to make a lot of changes! You can find them with grep -Ril @Linux.

For MacOS & lldb:

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.

Hosting a server

Since servers are really rare at this point in time here is a tutorial how to set up an Natural Selection server with hlds.

1. Follow these steps: https://developer.valvesoftware.com/wiki/SteamCMD
2. Copy the Natural Selection directory to steamcmd/servers/
3. Run the game :

./hlds_run -game ns -autoupdate +map ns_eclipse + sv_secure 1 + port 27015 + ip 127.0.0.1 +hostname "Natural Selection" +maxplayers 32

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

Under no circumstances expose your host to the internet!!! For more information follow this link.

In order to check if you 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 metamodp. Since players are also pretty rare you might want to install rcbot and therefore you have to download those files:

• rcbot without dlls
• rcbot linux dlls

Usefull links

• Usefull collection of ns files server addons, maps and erverything

• Great collection of ns guides/tutorials

• rcbot downloads

• dillinger.io markdown editor
