KEY BUTTONS
Continuous button event tracking is complicated by the fact that two different
input sources (say, mouse button 1 and the control key) can both press the
same button, but the button should only be released when both of the
pressing key have been released.
When a key event issues a button command (+forward, +attack, etc), it appends
its key number as a parameter to the command so it can be matched up with
the release.
state bit 0 is the current state of the key
state bit 1 is edge triggered on the up to down transition
state bit 2 is edge triggered on the down to up transition

/*
cvar_t variables are used to hold scalar or string variables that can be changed or displayed at the console or prog code as well as accessed directly
in C code.
it is sufficient to initialize a cvar_t with just the first two fields, or
you can add a ,true flag for variables that you want saved to the configuration
file when the game is quit:
cvar_t r_draworder = {"r_draworder","1"};
cvar_t scr_screensize = {"screensize","1",true};
Cvars must be registered before use, or they will have a 0 value instead of the float interpretation of the string. Generally, all cvar_t declarations should be registered in the apropriate init function before any console commands are executed:
Cvar_RegisterVariable (&host_framerate);
C code usually just references a cvar in place:
if ( r_draworder.value )
It could optionally ask for the value to be looked up for a string name:
if (Cvar_VariableValue ("r_draworder"))
Interpreted prog code can access cvars with the cvar(name) or
cvar_set (name, value) internal functions:
teamplay = cvar("teamplay");
cvar_set ("registered", "1");
The user can access cvars from the console in two ways:
r_draworder prints the current value
r_draworder 0 sets the current value to 0
Cvars are restricted from having the same names as commands to keep this
interface from being ambiguous.

The QuakeWorld connection process:
---------------------------------
servercount
Each time a server changes maps, it will bump the servercount variable. The signon
messages sent from the client to the server will include a servercount, and if the
server detects that it has changed levels while the client is in the process of
connecting, the client connection process will be restarted.
svc_skinlist
MAX_SIGNON_BUFFERS...
+attack;wait : this both does the attack and prints a chat?
put frag counts in userinfo as *frags?
no forward to server commands unless active?
changelevel / reconnect confusion
syncing the fixangle over the reliable channel with the first update
option to put the update in the reliable message?
--------------
A "connect <server>" command is executed on the client.
CL_Connect_f() disconnects from the current server if connected,
sets the current server to the new value, and sends the first connection packet.
The connection packet will be resent by CL_CheckForResend() every two seconds until the server connects.
A connection packet is an out of band packet containing "connect <userinfo>" with userinfo quoted.
--------------
The server receives the OOB message in SVC_DirectConnect()
It can respond with an OOB client print of "banned" or "server is full" if the client
cannot enter the game.
If the client can get in, the server will initialize a new client_t structure with a
netchan_t, and respond with an OOB message containing S2C_CONNECTION. Further
communication will be through sequenced netchan_t messages instead of OOB messages.
The client_t->state is set to cs_connected
--------------
if S2C_CONNECTION packet is dropped, the connect message will be resent after two
seconds and the server will recognize the address and reuse the allocated client_t FIXME:bug?)
When the client receives the S2C_CONNECTION, it initializes cls.netchan and sends
a "new" string command over the netchan to the server.
cls.state is set to ca_connected FIXME: change to cs_connected?
--------------
The "new" usercommand on the server is issued by the client every time they enter a level,
which is why none of the information is sent in the initial S2C_CONNECTION message.
"new" sends over
Before the client can begin playing in the server, the following information must be sent:
gamedir
svc_serverinfo
PROTOCOL_VERSION
servercount // for detecting when the server
gamedir // for deciding the add-on directory (qw, ctf, etc)
playernumber // the client will allways be in this slot
the qc string of world.message // usually the level's full verbose name
cdtrack
fullserverinfo
when received, the client changes state to ca_onserver. When the client receives
all the information needed to render a frame, the state will be changed to ca_active
.....
svc_soundlist
.....
svc_modellist
.....
prespawn passes the contents of the sv.signon_buffers, which hold
static entity spawning, static sound spawning, and all the entity baselines
FIXME: don't need to pass all baselines, uninitialized probs?
.....
"spawn" sends all dynamically changing state (fullclient updates, lightmaps, frags)
and ma
FIXME: 32 clients could be up to 16k in updates, which overflows the 8k packet size
FIXME: there is an updating hole between the sending of spawn data and the client
being notified
"begin"
Actually spawns the client into the world as a visible entity.
The client_t->state is set to cs_spawned, so normal datagram updates begin
-----------------------
When the first valid packetentities_t arrives at the client, cls.state is set
to ca_active, and rendering can begin.
FIXME: make sure player and packets are both valid
