Description/Features:
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
First of all, if you are too lazy to read all this don't bother me with problems or questions!
The plugin does several things that all can be turned on or off seperately by CVAR's:
- on startup it reads the available servers from SERVERFILE ("amxmodx/config/serverlist.ini" by default),
see next section for an example
- saying /server shows a list of available servers (if redirect_manual > 0) - people can choose a
number from the list and are immediately sent to that server
- when the server is full (one free slot left, that is) people are automatically forwarded to a random
server from the list - redirect_auto enables or disables this
- when a server from the list is full or down the server is disabled in the menu and players are not
redirected there automatically - to be able to check whether a server is down redirect_check_method
must be > 0 and to check whether it is full redirect_check_method must be > 1
- the servers are announced every redirect_announce seconds - set to 0 to turn announcements off;
the server list is shown as HUD message and for living players displayed at the top and for dead
players displayed somewhere below the top so it is not covered by the "spectator bars"; how much
information the announcements include depends on redirect_check_method
- depending on redirect_check_method servers can be checked for being down/full or even current map, number
of current players and maximum players can be displayed in the menu and in the announcements
- when no server is available for automatic redirection the player is just dropped with an appropriate
message
- when someone is redirected either manually or automatically this is shown to the other players
telling who was redirected and to which server
- it is also announced that people can say /follow to follow this player to the server and they are
redirected as well - both the announcements and the follow feature can be enabled or disabled by
CVAR (redirect_follow)
- the plugin is language aware (thus you need to place the xredirect.txt in amxmodx/data/lang/)
- the server can show whether someone that just connects was redirected to the server and from what
server he is coming from
- the own IP address is detected automatically and disabled in the server list - automatic detection
does not work if you use DNS names in the SERVERFILE - in this case set the DNS address of the own
server in redirect_external_address for the detection to work - detecting the own server is NECESSARY
for the plugin to work correctly
- with CVAR redirect_retry set to 1 the server can put people into a retry queue to be redirected back to
the last server (e.g. when they were automatically redirected but only want to play on the server they
connected to)
Server List File:
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
The file is in ini format. The section name is the server name. The following keys are recognized:
- address = server address (can be IP or DNS name)
- port = server port - a value between 1025 and 65536, default 27015
- cmdbackup = defines how often the UDP request is resent to the server (with redirect_check_method > 0), default 2
- noauto = overrides the redirect_auto setting for this server, default is redirect_auto
- nomanual = if set to 1, users can't manually redirect themselves to this server
- nodisplay = if this is set to 1 it will hide the server from the /server list and announcements, default 0
- adminslots = if this is set to 1 the plugin will redirect only people with reserved slot there if it's e.g. 12/13 players on the target server, default 0
- password = the password that is needed to connect to the server, default <none>
- publicpassword = if set to 1, all players can connect to passworded servers, when set to 0 only admins, default 0
If a value is not specified the default value is used. The "address" key always must be specified and
doesn't have a default value
Here is an example how the server file could look like:
/¯¯¯¯¯¯¯¯¯¯ serverlist.ini ¯¯¯¯¯¯¯¯¯¯¯¯\
[my example server]
address=example.n-ice.org
localaddress=192.168.0.3
port=27015
cmdbackup=5
noauto=1
nomanual=0
nodisplay=0
[my 2nd example server]
address=example2.n-ice.org
port=27015
\______________________________________/
I recommend that all servers have the same SERVERFILE. This is not necessary with redirect_show 0 but it's still better,
because it could confuse users when not all servers are in the same place in the menu on every server.
Please be aware that when using more than 6 servers in SERVERFILE you have to change the define
MAX_SERVERFORWARDS and recompile the plugin. If there are more servers in the file than specified by
MAX_SERVERFORWARDS the other servers will be ignored.
Available CVAR's:
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
redirect_active - 1/0 activate/deactivate redirect plugin - when this is set to 0 all other CVAR's are ignored, default 0
redirect_auto - 0 = disable automatic redirection
- 1 = only redirect when server is full, redirect to random server
- 2 = only redirect when server is full, redirect to next server in list
- 3 = always redirect except admins, redirect to random server
- 4 = always redirect except admins, redirect to next server in list
- 5 = always redirect including admins, redirect to random server
- 6 = always redirect including admins, redirect to next server in list
redirect_manual - controls behaviour of manual redirect menu:
- 0 = disabled
- 1 = selecting a server in main menu directly redirects there (if possible)
- 2 = selecting a server in main menu directly redirects there, or if not possible brings up a sub menu with detail information, the reason why redirection does not work and a retry option (if redirect_retry 1)
redirect_follow - 1/0 enable/disable following players with /follow to a server they were redirected to - people can still use /server to follow a player though, default 0
redirect_external_address - own external server address - only needed when you use DNS names instead of IPs in SERVERFILE - this must match the name in SERVERFILE - include the port!
redirect_check_method - check the servers in the list - 0 = no checks, 1 = ping only(to check whether a server is down), 2 = check active players and max. players as well, default 0
redirect_announce - announce server list with stats (depends on redirect_check_method) in center every redirect_announce seconds - set to 0 for off, default 60
redirect_announce_mode - control who announcements are displayed for: 1 = alive players , 2 = dead players, 3 = both
redirect_announce_alivepos_x - the vertical position of the announcements displayed to living people, default -1.0
redirect_announce_alivepos_y - the horizontal position of the announcements displayed to living people, default 0.01
redirect_announce_deadpos_x - the vertical position of the announcements displayed to living people, default -1.0
redirect_announce_deadpos_y - the horizontal position of the announcements displayed to living people, default 0.35
redirect_show - 1/0 enable/disable redirection information in chat area, default 1
redirect_adminslots - 1/0 enable/disable adminslots - when set to 1 people are redirected off the server when someone with a reserved slot connects, default 0
redirect_retry - 1/0 enable/disable retry queue feature - when set to 1 players can say /retry and are redirected as soon as a slot on the target server is free
redirect_hidedown - control hiding of servers that are down (not responding): 0 = don't hide, 1 = hide in menu, 2 = hide in announcements, 3 = hide in menu and announcements - has no effect with redirect_check_method 0, default 0
redirect_localslots - 1/0 enable/disable slot reserving for local players - remote players are redirected off the server when a local player connects
Advanced users should also check out the defines for more options, especially QUERY_INTERVAL could be interesting.
Min. Requirements:
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
- Metamod v1.18
- HLDS v3.1.1.1
- AMXX v1.70
Modules:
¯¯¯¯¯¯¯¯¯
The plugin requires the modules engine and sockets to be loaded. You can enable them in your modules.ini.
If you don't want to load the sockets module search for the line containing require_module("sockets")
and comment it out or delete it. When doing this you can only use redirect_check_method 0. If you set
this to something different your server might crash or other problems arise.
Known issues:
¯¯¯¯¯¯¯¯¯¯¯¯¯
#1 some people report crashes with CS 1.6 and redirect_check_method 1/2 if the server being checked
is on the same IP (only different port) so set to 0 if your server hangs after some time
#2 as the length of menu items is limited don't specify too long server names - if an item is too long it is just truncated
Changelog:
¯¯¯¯¯¯¯¯¯¯
Note:
The first version that was released to the public was v0.3. v0.1 and v0.2 were only running on my
servers for some time before I started the next version.
v0.1:
- reads the available servers from a config file
- people can show a server menu by saying /server
- automatic server forwarding to the next server in the list when server is full
- announcing of redirection for other players on the server
- people can say /follow to follow the last forwarded player
- when redirect_external_address is set the own address is automatically detected
v0.2:
- external address is automatically detected without having redirect_external_address set, for DNS names redirect_external_address
is still needed to be set though
- introduced CVAR redirect_check_method where
0 = disabled
1 = the servers in the list are pinged every QUERY_INTERVAL seconds to check whether they are online
2 = the servers in the list are queried for actual and maximum players and map every QUERY_INTERVAL seconds
- depending on redirect_check_method the menu displays:
0 = own server as disabled, others as available in format: server name (server address)
1 = own server as disabled, others as available in format "server name (server address)" or down in format "server name (server address) (down)"
2 = own server as disabled, others as available in format "server name [current map] (active players/max. players)"
or down in format "server name (server address) (down)"
- servers that are down are displayed as down in the list and people cannot have themselves redirected there (disabled in menu)
- random automatic forward instead of choosing the next free server from the list
- the server doesn't forward to servers considered being down when server is full
- if no server is available (due to being down) players are not redirected and have a message displayed that they couldn't be forwarded
v0.3
- for redirect_check_method 2:
- no automatic redirection to full servers anymore (active players = maximum players)
- full servers are displayed in the menu with red brackets surrounding the player numbers and can't be selected
- the plugin is now language system aware
- introduced CVAR redirect_send_tag where
0 = disabled
1 = when redirecting it prepends [R<server number>] to people's names with <server number> being the own server number in SERVERFILE
indicating to the receive server that this player was redirected from this server
- introduced CVAR redirect_receive_tag where
0 = disabled
1 = when someone connects with prepended [R<server number>] to his name the server will show a message that the player was redirected
from that server and remove the tag from the name
- introduced CVAR redirect_announce:
The value of this CVAR can be 0 for turning announcements of. If set to a higher floating point
value this is the time in seconds how often the announcements are shown.
- made status detection more stable by sending more UDP packets
- made status detection more stable through a completely new code for receive handling
- several small optimizations and bug fixes here and there I don't recall in detail :P
v0.4
- modified default messages for connect and team joining so that they display player names without redirect
tags if redirect_receive_tag = 1
- modified the name change code to be more reliable
- HL1 steam server status querying is now working - this should make status information work for all HL1
mods running on Steam
- plugin now uses the much faster cvar querying introduced with AMXX 1.70
- load routine now checks whether there are more servers in the file than can be loaded
v0.4.1
- name changes from tagged names are now hidden as well - this means with redirect_receive_tag = 1 the
complete procedure of tagging is hidden
v0.4.7
- fixed a bug where automatic redirection didn't work with redirect_check_method 0
- fixed a bug where the PLUGIN_TAG was missing in the message MSG_NO_REDIRECT_SERVER

- added code to require_module sockets
- introduced cvar redirect_version for external version check
v0.5.0

v0.6.0
- sorted out several unused variables
- redirect_auto 2 redirects to next server in list (1 = random server, like before)
- added new format for SERVERFILE - it is now an ini file
- server status (or ping) request should be more stable due to added cmdbackup of 2 (2 additional request packets are sent)
- the default cmdbackup value can be overridden in SERVERFILE for each server
- redirect_manual can be overriden in SERVERFILE for each server
