-- NPC Chat code by Zorman2000
|
||||
-- Chat system consists of chatline and options objects that are re-used to create a conversation.
|
||||
-- The objects are the following:
|
||||
--
|
||||
-- chatline = { text = "", options = {}, name = "", flag = "" }
|
||||
-- 1. text: What the NPC says on this chat line
|
||||
-- 2. options: What the player can answer to the chat line. Options are of another type of chat lines.
|
||||
-- If you want the player to have no options to answer, set to nil
|
||||
-- 3. name: The name of the NPC that will use this line. Use this when you want a specific NPC
|
||||
-- to speak this line.
|
||||
-- 4. flag: When the NPC speaks this line, this flag will be set into the entity's metadata.
|
||||
--
|
||||
-- options = { opt = "", answer = { chatline }
|
||||
-- 1. opt: The text that the player can say to the NPC
|
||||
-- 2. answer: A chatline object (as described above)
