## Define Documentation

#define CMD_MSG | ( | x |  | ) | ((x) << 16)

Used to combine a StringID with the command.

This macro can be used to add a StringID (the error message to show) on a command-id (CMD_xxx). Use the binary or-operator "|" to combine the command with the result from this macro.

Parameters:

  | x | The StringID to combine with a command-id

## Typedef Documentation

typedef void CommandCallback(const CommandCost &result, TileIndex tile, uint32 p1, uint32 p2)

Define a callback function for the client, after the command is finished.

Functions of this type are called after the command is finished. The parameters are from the CommandProc callback type. The boolean parameter indicates if the command succeeded or failed.

Parameters:

  | result | The result of the executed command
  | tile | The tile of the command action
  | p1 | Additional data of the command
  | p1 | Additional data of the command

  CommandProc

Definition at line 403 of file command_type.h.

typedef CommandCost CommandProc(TileIndex tile, DoCommandFlag flags, uint32 p1, uint32 p2, const char *text)

Defines the callback type for all command handler functions.

This type defines the function header for all functions which handles a CMD_* command. A command handler use the parameters to act according to the meaning of the command. The tile parameter defines the tile to perform an action on. The flag parameter is filled with flags from the DC_* enumeration. The parameters p1 and p2 are filled with parameters for the command like "which road type", "which order" or "direction". Each function should mentioned in there doxygen comments the usage of these parameters.

Parameters:

  | tile | The tile to apply a command on
  | flags | Flags for the command, from the DC_* enumeration
  | p1 | Additional data for the command
  | p2 | Additional data for the command
  | text | Additional text

Returns:
  The CommandCost of the command, which can be succeeded or failed.

## Enumeration Type Documentation

anonymous enum

Defines some flags.

This enumeration defines some flags which are binary-or'ed on a command.

Enumerator:

  CMD_NETWORK_COMMAND | execute the command without sending it on the network
  CMD_NO_TEST_IF_IN_NETWORK | When enabled, the command will bypass the no-DC_EXEC round if in network.
  CMD_FLAGS_MASK | mask for all command flags
  CMD_ID_MASK | mask for the command ID

Definition at line 336 of file command_type.h.

anonymous enum

Command flags for the command table _command_proc_table.

This enumeration defines flags for the _command_proc_table.

Enumerator:

  CMD_SERVER | the command can only be initiated by the server
  CMD_SPECTATOR | the command may be initiated by a spectator
  CMD_OFFLINE | the command cannot be executed in a multiplayer game; single-player only
  CMD_AUTO | set the DC_AUTO flag on this command
  CMD_ALL_TILES | allow this command also on MP_VOID tiles
  CMD_NO_TEST | the command's output may differ between test and execute due to town rating changes etc.

Definition at line 348 of file command_type.h.

anonymous enum

List of commands.

This enum defines all possible commands which can be executed to the game engine. Observing the game like the query-tool or checking the profit of a vehicle don't result in a command which should be executed in the engine nor send to the server in a network game.
