I came up with something sorta like C# class's. This makes building packets in memory simple, fast, and easy. And the include itself takes less then 5 minutes to write!

Code: Select all

; ----------------------------

Global Pos = 0

; ------------------------------------------------------------
;   AddInt32 - Add Integer To Memory
; ------------------------------------------------------------
Procedure AddInt32(*Memory, iData.l)
  PokeL(*Memory + Pos, iData)
  Pos = Pos + 4
EndProcedure

; ------------------------------------------------------------
;   AddByte - Add Byte To Memory
; ------------------------------------------------------------
Procedure AddByte(*Memory, bData.b)
  PokeB(*Memory + Pos, bData)
  Pos = Pos + 1
EndProcedure

; ------------------------------------------------------------
;   AddBytes - Add Bytes To Memory
; ------------------------------------------------------------
Procedure AddBytes(*oldMemory, *newMemory, DataSize)
  MoveMemory(*oldMemory, *newMemory + Pos, DataSize)
  Pos = Pos + DataSize
EndProcedure

; ------------------------------------------------------------
;   AddString - Add String To Memory
; ------------------------------------------------------------
Procedure AddString(*Memory, sData.s)
  PokeS(*Memory + Pos, sData, Len(sData))
  Pos = Pos + Len(sData)
EndProcedure

; ------------------------------------------------------------
;   FreePos - Reset Pos Pointer
; ------------------------------------------------------------
Procedure FreePos()
  Pos = 0
EndProcedure

Then you could do something simple like...

Code: Select all

Procedure SendPacket(ClientID)
  
  Protected *Packet = AllocateMemory(100)
  
  AddByte(*Packet, $01)
  AddByte(*Packet, $02)
  
  SendNetworkData(ClientID, *Packet, Pos)
  
  FreeMemory(*Packet)
  FreePos()
  
EndProcedure

And it will send 01 02. I only need them three data types, but you can add all the other in a minute.

Sorry, but this is not correct!

Code: Select all

; ------------------------------------------------------------
;   AddInt32 - Add Integer To Memory
; ------------------------------------------------------------
Procedure AddInt32(*Memory, iData.i)
  PokeI(*Memory + Pos, iData)
  Pos = Pos + SizeOf(Integer)
  ProcedureReturn Pos
EndProcedure 

; or:
Procedure AddInt32(*Memory, iData.l)
  PokeL(*Memory + Pos, iData)
  Pos = Pos + 4
  ProcedureReturn Pos
EndProcedure
