Function Documentation

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

Control the companies: add, delete, etc.

Parameters:
tile unused
flags operation to perform
p1 various functionality
  • p1 = 0 - create a new company, Which company (network) it will be is in p2
  • p1 = 1 - create a new AI company
  • p1 = 2 - delete a company. Company is identified by p2
  • p1 = 3 - merge two companies together. merge #1 with #2. Identified by p2
p2 various functionality, dictated by p1
  • p1 = 0 - ClientID of the newly created client
  • p1 = 2 - CompanyID of the that is getting deleted
  • p1 = 3 - #1 p2 = (bit 0-15) - company to merge (p2 & 0xFFFF)
    • #2 p2 = (bit 16-31) - company to be merged into ((p2>>16)&0xFFFF)
Todo:
In the case of p1=0, create new company, the clientID of the new client is in parameter p2. This parameter is passed in at function DEF_SERVER_RECEIVE_COMMAND(PACKET_CLIENT_COMMAND) on the server itself. First of all this is unbelievably ugly; second of all, well, it IS ugly! Someone fix this up :) So where to fix?
  • - network_server.c:838 DEF_SERVER_RECEIVE_COMMAND(PACKET_CLIENT_COMMAND)
  • - network_client.c:536 DEF_CLIENT_RECEIVE_COMMAND(PACKET_SERVER_MAP) from where the map has been received
