| − | ==Overview==
| + | Please check the svn repository for a more up-to-date launcher protocol document |
| | | | |
| − | This is the Odamex Launcher protocol, which will help developers develop custom launchers in other programming languages
| + | It is available in [http://en.wikipedia.org/wiki/OpenDocument OpenDocument Text] format [http://odamex.net/svn/root/trunk/documentation/tech/query_protocol.odt here] |
| − | | + | |
| − | ==Transport notes==
| + | |
| − | | + | |
| − | * This protocol uses UDP (User Datagram Protocol) as its transport medium.
| + | |
| − | * All packets are uncompressed.
| + | |
| − | * All data is little endian.
| + | |
| − | | + | |
| − | ==Types used==
| + | |
| − | | + | |
| − | These are the types used in this specification

| − | ==Additional Notes==
| + | |
| − | | + | |
| − | * Token is unnecessary for a launcher I think.
| + | |
| − | * First PWAD is always the IWAD
| + | |
| − | * Game types are: 0 = COOP, 1 = Deathmatch, 2 = Deathmatch 2.0
| + | |
| − | * Skill levels are: 0 = ITYTD, 1 = HNTR, 2 = HMP, 3 = UV, 4 = NM (Acronyms).
| + | |
| − | * Player teams are: 0 = None, 1 = Blue, 2 = Red, 3 = Gold
| + | |
| − | * If CTF is enabled, Teamplay will be enabled and deathmatch (2.0?).
| + | |
| − | * If Teamplay is enabled, then deathmatch (2.0?) will be too.
| + | |
| − | * Scorelimit, team scores and player teams (excluding team 0) only appear if Teamplay/CTF is enabled.
| + | |
| − | * The Game version field can be deciphered using the following calculations
| + | |
| − | ** Major - (gameversion / 256)
| + | |
| − | ** Minor - ((gameversion % 256) / 10)
| + | |
| − | ** Release - ((gameversion % 256) % 10)
| + | |
| − | | + | |
| − | == Possible Future Protocol Improvements ==
| + | |
| − | | + | |
| − | === Data structuring ===
| + | |
| − | | + | |
| − | * Container (header based) protocol which would contain: Magic Tag, Size, Version (see above) and the data, this would allow features to be added in any order in 1 packet without breaking it, so if the launcher/server can't understand the magic value, it'll bypass it, via jumping past the entire size of the unknown header to the next one.
| + | |
| − | * Packets will have a size, to indicate their boundary, including a null termination
| + | |
| − | * Strings will have a size value, including the null termination.
| + | |
| − | * Strings will be UTF-8 encoded. (Unicode)
| + | |
| − | | + | |
| − | === Protocol additions ===
| + | |
| − | | + | |
| − | * Dedicated Odamex Query/Response values (rather than old csdoom ones)
| + | |
| − | * Proper versioning, with possible subversion number.
| + | |
| − | * Operating system information the server is running on.
| + | |
