-- CommandState.lua
|
|
|
|
-- Implements the cCommandState class representing a command state for each VIP player
|
|
|
|
--[[
|
|
The command state holds internal info, such as the coords they selected using the wand
|
|
The command state needs to be held in a per-entity manner, so that we can support multiple logins
|
|
from the same account (just for the fun of it)
|
|
The OOP class implementation follows the PiL 16.1
|
|
|
|
Also, a global table g_CommandStates is the map of PlayerEntityID -> cCommandState
