I've been wondering this lately, what are they and what are they for? I'll trying typing them into the console but they don't do anything. Are these supposed to be put into server.cfg or something?

Shortish:

Client variable. Some of them are client side, some of them are server side. The server's cvars can only be changed directly from it's console or through rcon.

Server.cfg is used to set values for cvars when the server start.

[Snaggle]

If you're having problems setting them while the server is in use, use the sm_cvar command to do it.

E.G sm_cvar mp_autoteambalance "1"

Pretty sure that works!

cvar = convar = console variable

[Ade]

yup, console variables; there's also concommands=console commands

syntax:
cl_ denotes client cvars; sv_ denotes server cvars; mp_ denotes server cvars related to gameplay; tv_ denotes server cvars/commands related to sourcetv; sm_ ofc is used for sourcemod cvars/commands
(most of) the rest, that don't start with those prefixes, are commands

use:
when typing a cvar in console, it automatically displays default value and info; to change that cvar, it must be followed by a parameter/value
when typing a command in console (some can have parameters), it just executes it


PS: pls correct me if necessary

Game specific cvars sometimes start with the game abbreviation instead, such as tf_weapon_criticals for TF2.
