BATTLEZONE

Version 1.5.2.23 Preview 1

Released 2014-07-26

This version adds major new Lua mission scripting features. In particular, it adds event handlers for game object created (CreateObject), player joined session (CreatePlayer), player finished loading (AddPlayer), and player left session (DeletePlayer). Mission scripts running on different machines in a multiplayer session can now send user-defined network messages to each other.

Scripting

• Made team and odf parameters optional in CountUnitsNearObject
• LuaMission supports network Send/Receive
  • Send(to, type, data): send user-defined packet to recipient(s)
  • Receive(from, type, data): called when a user-defined packet arrives
  • The "to" parameter is a network id (nil or 0 for broadcast)
  • The "from" parameter is a network id (0 for system)
  • Type is a single-character string indicating the message type
  • Data is an arbitrary string up to 241 characters long
  • Lua converts non-string values to strings for transmission
  • Can use string.char to construct a string from numeric character codes
  • Can use string.byte to extract numeric character codes from a string
• Mission game object events
  • CreateObject: called for any new game object
  • AddObject: also called for game objects loaded from a mission file (BZN)
• Mission net player events
  • CreatePlayer(id, name, team): called when a player joins the session
  • AddPlayer(id, name, team): called when a player finishes loading and starts running
  • DeletePlayer(id, name, team): called when a player leaves the session
  • The "id" parameter is the network id for that player

Stability

• Fixed memory corruption when using Modem transport
• Fixed MultGMission crashing when one team scores
  • Anet dpSent added data after the packet, corrupting the stack

  • Not sure how it got into that state, though... :|
