Arrumar um problema script

Postado Dezembro 6, 2014 10 anos

Achei e editei esse script vendedor de magias, mas o problema dele é que quando o npc diz quais magias ele vai vender, chega num limite ai só manda algumas

Tava pensando em:

Só mostrar as magias que o jogador ainda não comprou

Ou qualquer outra coisa quem puder me ajudar dou 6reps
