Evennia Talkative NPC
|
|
|
|
Contribution - Griatch 2011
|
|
|
|
This is a simple NPC object capable of holding a
|
|
simple menu-driven conversation. Create it by
|
|
creating an object of typeclass contrib.talking_npc.TalkingNPC,
|
|
For example using @create:
|
|
|
|
@create John : contrib.talking_npc.TalkingNPC
|
|
|
|
Walk up to it and give the talk command
|
|
to strike up a conversation. If there are many
|
|
talkative npcs in the same room you will get to
|
|
choose which one's talk command to call (Evennia
|
|
handles this automatically).
|
|
|
|
Note that this is only a prototype class, showcasing
|
|
the uses of the menusystem module. It is NOT a full
|
|
mob implementation.
