Criando roguelike no Unity do zero

Etapa 0 - planejamento

1. Geração de mapas de masmorras
2. Personagem do jogador e seu movimento
3. Área de visibilidade
4. Inimigos
5. Procure uma maneira
6. Luta, Saúde e Morte
7. Nível do Jogador
8. Itens (armas e poções)
9. Fraudes do console (para teste)
10. Pisos de masmorra
11. Salvando e carregando
12. Chefe final

Etapa 1 - Classe MapManager

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MapManager 
{
    public static Tile[,] map; // the 2-dimensional map with the information for all the tiles
}

public class Tile { //Holds all the information for each tile on the map
    public int xPosition; // the position on the x axis
    public int yPosition; // the position on the y axis
    public GameObject baseObject; // the map game object attached to that position: a floor, a wall, etc.
}

Etapa 2 - algumas palavras sobre a estrutura de dados

Etapa 3 - um pouco mais sobre a estrutura de dados

Etapa 4 - Algoritmo de geração de masmorra

1. Corte a sala no centro do mapa
2. Selecione aleatoriamente uma das paredes
3. Atravessamos o corredor nesta parede
4. Selecione aleatoriamente um dos elementos existentes.
5. Selecione aleatoriamente uma das paredes deste elemento
6. Se o último item selecionado for uma sala, geramos um corredor. Se o corredor, escolha aleatoriamente se o próximo elemento será uma sala ou outro corredor
7. Verifique se há espaço suficiente na direção selecionada para criar o item desejado
8. Se houver um local, crie um elemento; caso contrário, retorne à etapa 4
9. Repita da etapa 4

Etapa 5 - cortar a sala

Etapa 6 - desenhar a primeira sala
