I've been trying to think of a way, to manage messages for NPC's. I am trying to categorize the messages into groups such as 'Greetings','Goodbyes',etc. Then, the NPC's can randomly choose a message from this group to say. I was thinking a linked list possibly, but I never really used a linked list! What can I use to group things into categories? Anyone have any ideas, because I'm not coming up with anything Thanks!
