i loled at your sig.
but creating dialogues is easy.. idk what you want..but you can just do this?
case NPCID:
c.getDH().sendDialogues(1, 1);
break;
then go to dialoguehandler and add the dialogues
case 1:
sendNpcChat1("Hi, i give you 10m okay.",c.talkingNpc,"Archer");
c.getItems().addItems(995, 100000000;
c.nextChat = 0;
break;
