Callbacks
=========
**Callbacks** trigger on specific server events.
qagame execution
================
et_InitGame( levelTime, randomSeed, restart )
---------------------------------------------
Called when qagame initializes.
* **levelTime** is the current level time in milliseconds.
* **randomSeed** is a number that can be used to seed random number generators.
* **restart** indicates if et_InitGame() is being called due to a `map_restart` (1) or not (0).
et_ShutdownGame( restart )
--------------------------
Called when qagame shuts down.
* **restart** indicates if the shutdown is being called due to a `map_restart` (1) or not (0).
et_RunFrame( levelTime )
------------------------
Called when qagame runs a server frame.
* **levelTime** is the current level time in milliseconds.
et_Quit()
---------
Called when Legacy unloads the mod.
The mod should close all open filedescriptors and perform all cleanup.
Client management
=================
rejectreason = et_ClientConnect( clientNum, firstTime, isBot )
--------------------------------------------------------------
Called when a client attempts to connect to the server.
* **clientNum** is the client slot id.
* **firstTime** indicates if this is a new connection (1) or a reconnection (0).
* **isBot** indicates if the client is a bot (1) or not (0).
If the mod accepts the connection, it returns **nil**. Otherwise, the mod should return a string describing the reason the client connection was rejected.
et_ClientDisconnect( clientNum )
--------------------------------
Called when a client disconnects.
* **clientNum** is the client slot id.
et_ClientBegin( clientNum )
---------------------------

* **clientNum** is the client slot id.
et_ClientUserinfoChanged( clientNum )
-------------------------------------
Called when a client's Userinfo string has changed.
* **clientNum** is the client slot id.
.. note:: This only gets called when the players `CS_PLAYERS` config string changes, rather than every time the userinfo changes. This only happens for a subset of userinfo fields.
et_ClientSpawn( clientNum, revived, teamChange, restoreHealth )
---------------------------------------------------------------
Called when a client is spawned.

Returns 1 if the command was intercepted by the mod, and 0 if the command was ignored and passed through to the server (and other mods in the chain).
