Fixes an exploit where players can manipulate game time to perform actions instantly (using progress triggers, detonating grenades, firing, etc.). It does so by clamping the number of seconds a client's internal clock can be offset by, relative to server time.

• This plugin can cause rubberbanding for players if sm_tickbase_shift_max_seconds is set too low. 2.0 works for me, but might require higher values for your setup

• A detection does not mean a client is cheating. Legit players will have logs due to packet loss, server choke, etc. It's left to your discretion to analyze this data and act on it accordingly.

• Upgrade to Sourcemod 1.11 or higher, else install DHooks2
• Download the latest zip in releases
• Extract contents into addons/sourcemod
• Refresh your plugin list (sm plugins refresh in server console)

Cvars should be modified in cfg/plugin.tickbase-manipulation-fix.cfg

• sm_tickbase_shift_max_seconds (Default: 2)

  • How far ahead from server time a client is allowed to be (don't touch unless you know what you're doing)

• sm_tickbase_shift_log_seconds (Default: 25)

  • Logs the name and steamID of clients that are ahead of server time by more than this many seconds. Set to 0 to disable

• No More Room in Hell
• Team Fortress 2
• Contagion
• Pirates, Vikings, and Knights II
• Day of Defeat: Source
• Zombie Panic Source (2.4 only)
• Any other game where the current signature matches, I guess

If you want support for your game please submit a pull request with valid gamedata or open an issue.

^{Hint: The signature for CPlayerMove::RunCommand can sometimes be found by searching for the string "sv_maxusrcmdprocessticks_warning at server tick %u:" in a disassembler. It also references sv_noclipduringpause}
