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
