Like 0x3108 and 0x3109 till 0x310F, etc. * This way we can use the lower 8 values for public releases. * * Reasons why it changed in the past: * 3.0.1: rewrite of contact pack protocol, because of * different structure layout rules on different architectures. * 3.0.2: rewrite of setup transmit from server to client to * make it possible for 64-bit machines and 32-bit machines * to join in the same game. This was the last hardcoded * structure that was shared between client and server. * 3.0.3: implemented a version awareness system, so that * newer clients can join older servers and so that * newer servers can support older clients. * The client maintains a 'version' variable indicating * the version of the server it has joined and the server * maintains for each connection a 'connection_t->version' * and a 'player->version' variable. * 3.0.4: the so-called 'pizza-mode' introduced a new packet type. * The score packet now also includes pl->mychar. * 3.0.4.1: new laser weapon introduces another packet change. * Because there is an unofficial (and forbidden) 3.0.4 version floating * around the sub patchlevel number is used to distinguish versions. * A new display packet to tell the server what the view sizes are * and how many different debris intensities the client wants. * 3.0.4.2: new player-self status byte in self packet. * 3.0.4.3: different and incompatible laser packet. * New eyes packet to tell the client through wich players eyes we're * looking through in case the client is in game over move and it is locked * on someone else. * 3.1.0.0: new big patches implementing loads of new incompatible features. * Major cleanup. Old clients (before 310) can't join new servers anymore. * 3.1.0.1: key-change-ids are now send as longs instead of bytes. * 3.1.0.2: different player status byte. * 3.1.0.3: different mine packet. * 3.2.0.0: New ship shape definition and big patches. * 3.2.0.1: Extended buffer for very large ship shape definitions. * 3.2.0.2: New mouse pointer control packet. * 3.2.5.0: Now client must ask for audio packets in order to get them. * 3.2.6.0: New map update packet. * 3.2.6.1: New player timing packet. * 3.2.8.0: New asyn packet. * 3.3.1.0: Different owner-only commands. * 3.3.2.0: Map decorations. * 3.4.0.0: Lose/drop item key. * 3.5.0.0: Player waiting queue. * 3.8.0.0: new items (deflector, hyperjump, phasing), keyboardsize and rounddelay. * 4.1.0.0: new item (mirror). * 4.2.0.0: new power/turnspeed behavior * 4.2.0.1: new item (armor). * 4.2.0.2: highest bit on in wreckagetype when deadly. * 4.2.0.3: different way of sending player item info. * 4.2.1.0: high bit in radar size means player is a teammate. * 4.3.0.0: transmit phasing separately from cloaking * 4.4.0.0: new object (asteroid) * 4.4.0.1: fast radar packet * 4.5.0.0: new team score packet; score packet made larger to send decimals * 4.5.0.1: temporary wormholes * Polygon branch * 4.F.0.9: 4.3.0.0 + xp2 map format * 4.F.1.0: Send_player(): Additional %c (1 when sending player's own info). * 4.F.1.1: support for everything in 4.5.0.1 * 4.F.1.2: Show ships about to appear on bases, new team change packet. * 4.F.1.3: cumulative turning * 4.F.1.4: balls use polygon styles * 4.F.1.5: Possibility to change polygon styles. */ #ifdef SERVER #define MAGIC (is_polygon_map ? 0x4F15F4ED : 0x4501F4ED) #else #define MAGIC (instruments.blockProtocol ? 0x4501F4ED : 0x4F15F4ED) #endif #define MAGIC2VERSION(M) (((M) >> 16) & 0xFFFF) #define VERSION2MAGIC(V) ((((V) & 0xFFFF) << 16) | (MAGIC & 0xFFFF)) #define MY_VERSION MAGIC2VERSION(MAGIC) /* * Which client versions can join this server. */ #ifdef SERVER #define MIN_CLIENT_VERSION 0x4203 #define MAX_CLIENT_VERSION MY_VERSION #endif /* * Which server versions can this client join. */ #define MIN_SERVER_VERSION 0x4F09 #define MAX_SERVER_VERSION MY_VERSION /* * We want to keep support for servers using the old map format in the client, * but make incompatible changes while developing the new format.
