+# Sistema de missão para mansão 2D (Unity)
+
+Este repositório inclui scripts base para o cenário pedido:
+
+- 3 NPCs pedindo itens específicos.
+- NPC aceita **somente** o item correto.
+- Itens com spawn aleatório nas salas da mansão.
+- Portas para transitar entre salas.
+
+## Scripts
+
+- `ItemType.cs`: enum com os tipos de item.
+- `Inventory2D.cs`: inventário simples do jogador.
+- `ItemPickup.cs`: coleta itens ao encostar no jogador.
+- `NPCRequester.cs`: valida entrega de item no NPC ao pressionar `E`.
+- `RandomItemSpawner.cs`: sorteia e instancia itens em pontos de spawn.
+- `DoorTeleporter.cs`: teleporta jogador para outra sala ao interagir com porta.
+- `MansionQuestManager.cs`: distribui pedidos aos NPCs e detecta conclusão.
+
+## Configuração rápida
+
+1. Adicione `Inventory2D` no objeto Player (com tag `Player`).
+2. Crie prefabs de item com `Collider2D` trigger + `ItemPickup`.
+3. Em cada NPC, adicione `Collider2D` trigger + `NPCRequester`.
+4. Crie um objeto `GameManager` com `MansionQuestManager` e referencie os 3 NPCs.
+5. Configure `possibleRequests` com os tipos de item permitidos.
+6. Crie um objeto `RandomItemSpawner`, informe `spawnPoints` e os prefabs dos itens.
+7. Em cada porta, adicione `DoorTeleporter` e informe o `destinationPoint` da próxima sala.
+
+## Fluxo de jogo
+
+- Jogador explora salas da mansão.
+- Coleta itens sorteados nos pontos de spawn.
+- Entra em portas para acessar novas salas.
+- Entrega cada item no NPC correto usando `E`.
+- Quando os 3 NPCs estiverem satisfeitos, `onAllNPCsSatisfied` é disparado.
