Créer roguelike dans Unity à partir de zéro

Étape 0 - planification

1. Génération de carte de donjon
2. Le personnage du joueur et son mouvement
3. Zone de visibilité
4. Ennemis
5. Rechercher un moyen
6. Combat, santé et mort
7. Niveau supérieur du joueur
8. Objets (armes et potions)
9. Cheats de la console (pour les tests)
10. Planchers de donjon
11. Sauvegarde et chargement
12. Boss final

Étape 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.
}

Étape 2 - quelques mots sur la structure des données

Étape 3 - un peu plus sur la structure des données

Étape 4 - Algorithme de génération de donjon

1. Coupez la pièce au centre de la carte
2. Sélectionnez au hasard l'un des murs
3. Nous traversons le couloir dans ce mur
4. Sélectionnez au hasard l'un des éléments existants.
5. Sélectionnez au hasard l'un des murs de cet élément
6. Si le dernier élément sélectionné est une pièce, nous générons un couloir. Si le couloir, choisissez au hasard si l'élément suivant sera une pièce ou un autre couloir
7. Vérifiez s'il y a suffisamment d'espace dans la direction sélectionnée pour créer l'élément souhaité
8. S'il y a un lieu, créez un élément, sinon, revenez à l'étape 4
9. Répétez à partir de l'étape 4

Étape 5 - découpez la pièce

Étape 6 - dessiner la première salle
