lol to edit it you have to use the UID number you got from your NPC , and go to client and type something like
if (NPCID == 104800)
(
Npc.say: blabhalbha
)
then u put in the do section
if (NPCID == 104800)
(
if optin 1 : mychar.teleport( 1005,50,50)
)
just look at the cpd admin you will understand it probably, thats how i understood npcs and then i started making my own =]
like free exppot event, trade db for met tear.. fix met teras and all that
