Boa noite,
Estou tentado fazer um npc que troca um item por outro. Mas até agora os scripts que vi no site, nenhum funcionou aqui.
Quero um npc que vc possa trocar item com ele quando quiser.
Pode até ser que os scripts do site funcionem, e eu que não saiba estar fazendo correto.
Se puderem mandar um bem explicado vou agradecer muito.
Estou fazendo um ot de poketibia.
Agradeço a atenção
