Editor de niveles (Parte 2)

En esta segunda parte del editor de niveles nos centraremos en la creación de las estructuras internas parar poder definir correctamente un nivel y la generación del archivo base a partir de un nivel con datos por defecto.


El objetivo es poder pulsar al botón de añadir nivel, que nos pregunte el número de etapa y genere la cuadrícula con una clase adjuntada en cada celda con la información interna que procesa, para que posteriormente poder editar las casillas y modificar los datos en esta estructura dinámicamente.


Una vez generado el nivel a través de la grid visual e interna en memoria, debemos poder salvar la información en un fichero para poder comprobar que estamos guardando correctamente la información y posteriormente mostrar y actualizar los ficheros encontrados en la carpeta de etapas a través de la lista que creamos en el primera parte del tutorial.



Clase Stage con el contructor y las variables de ficheros:
 using System.Collections.Generic;  
 using UnityEngine;  
 using System;  
 using System.Text;  
 [Serializable]  
 public class StageCell  
 {  
   public int x;  
   public int y;  
   public int listPos;  
   public int type;  
   public bool isFinal;  
   public bool isObjective;  
   public int water;  
   public int food;  
   public int troops;  
   public int weapons;  
   public int gold;  
 }  
 [Serializable]  
 public class Stage  
 {  
   public int version;  
   public int numStage;  
   public string nameStage;  
   public string fileName;  
   public List<StageCell> gridStage = new List<StageCell>();  
   public Stage()  
   {      
     DefaultCells cond = new DefaultCells();  
     version = cond.version;  
     numStage = 0;  
     nameStage = "";

     for (int i = 0; i < 64; i++)  
     {

       defaultCell.x = 0;  
       defaultCell.y = 0;  
       defaultCell.listPos = 0;  
       defaultCell.type = cond.type;

       defaultCell.troops = cond.troops;  
       defaultCell.weapons = cond.weapons;  
       defaultCell.gold = cond.gold;  
       gridStage.Add(defaultCell);  
     }  
   }  
 }  
 public class Levels : MonoBehaviour  
 {  
   public static void LoadLevel(int levelNum)  
   {  
     //load info from levels folder      
     TextAsset jsonTextFile = Resources.Load<TextAsset>("Levels/Attila" + levelNum.ToString());  
     object resultValue = JsonUtility.FromJson<Stage>(Encoding.ASCII.GetString(jsonTextFile.bytes));  
     Stage loadlevel = (Stage)Convert.ChangeType(resultValue, typeof(Stage));  
     GlobalInfo.stageVersion = loadlevel.version;   
     GlobalInfo.actualStage = loadlevel.numStage;  
     GlobalInfo.gridStage = loadlevel.gridStage;  
   }  
 }  

Hay que tener en cuenta que el sistema de ficheros no funciona en sistemas Android, ya que el sistema de protección del sistema impide acceder libremente en todas las carpetas del SO. Así mismo el editor esta pensado parar ser ejecutado en ordenador, diseñar las etapas y pasar el contenido a la carpeta Resouces donde el juego accederá a los niveles.
