From PsychoStats

PsychoStats supports accuracy and Hitbox weapon statistics for Half-Life and Half-Life 2 based game servers via extra server addon's. You must install one of these addon's for these statistics to be available. Depending on what game server you run see the appropriate section below.

Please note that in Team Fortress 2 the server does not provide hit location to a plugin author, so hitbox information will always be empty.

Half-Life Non-Source Servers

Half-Life 1 game servers that are not source based. The only viable option is to install AMX Mod X and enable the proper support within it as outlined below.

AMX Mod X

Install the server plugin AMX mod X.

Uncomment the following plugins from the amxmodx plugins.ini in your server directory: modtype/addons/amxmodx/config/plugins.ini

• restmenu.amxx
• statsx.amxx
• miscstats.amxx
• stats_logging.amxx

Half-Life Source Servers

Half-Life 2 game servers that are Source based. Only one of the server plugins below need to be installed. Choose the one that is best for your server environment. Note that at this time Stormtrooper's SourceMod spatial data plugin is not compatible with weapon stats logging plugins. If you use the spatial data plugin, damage and hit locations will not be logged.

• Mani's Admin Plugin
  • In mani_server.cfg set: mani_external_stats_log 1
• Roger Devil's Statsmeminimum (Requires Metamod: Source)
• HLStatsX (Requires SourceMod)
  • What you want is the free HLstatsX weapon logging plugin. There is a "premium" stats service which can be purchased, but you don't need that, all you need is that one plugin. If you are experiencing problems with headshots not being logged for Day of Defeat: Source, there is a modified version you can download here. You will need to add the following line to your server.cfg: "sm plugins reload weapon_logging"
• Keeper's HL2DM Plugin (VSP and Metamod: Source)
  • In keeper_hl2.cfg set: kp_statsme_enable "1"
