Advanced Npcsystem Para Nova Svn

lithium · Janeiro 23, 2007

Este é um NPC system do Jiddo da Equipe SVN criadora do Open Tibia

Características da versão 2.00:

- Classbased object structure*

- Sistema da fila do npc com suporte para uma quantidade infinita de jogadores em espera. - Sistema de manipulação avançado de keyword. Agora também com sustentação prolongada para quase tudo.

- Classe simples de NpcHandler para a maioria das características básicas do npc. - Distance checking system

- Comprar muitos items stackable non-stackable de uma só vez por exemplo 150 hams e 320 meats.

Tudo isto faz possível fazer enormes os npcs avançados da loja (e outros)

que usam somente aproximadamente 50-100 linhas no lua dos arquivos dos npcs.

Está aqui o código:
