FAQ

Q: Prerequisites?

• Powershell v5 and later or Powershell Core (aka pwsh)

Q: Verified games?

Engine	Games
Source (srcds)	cs2, csgo, hl2mp, left4dead2
Goldsource (hlds)	cstrike, czero, valve. Should work for all hlds games.

The functions will probably work on a lot more games than those in the list.

Q: ping query not working for some games?

A2A_PING is no longer supported on Counter Strike: Source and Team Fortress 2 servers, and is considered a deprecated feature. See official documentation here for more information.

Notes

The functions are stateless - that is, SourceQuery, SourceRcon, and GoldsourceRcon are pure functions, storing no authentication or challenge states. This is to be expected for Source Queries, but not for Rcon. A possible future area of improvement would be to make SourceRcon and GoldsourceRcon construct and return a stateful Rcon object, that would improve client performance especially when multiple rcon commands need to be executed in sequence.
