使用c# 5分钟 创建一个Roguelike 游戏

原文链接不给了，之前贴链接blog被封了

本文章是简单翻译了原文，如果不知道什么是Roguelike游戏的，请自行百度。。。原因同上

因为原文的代码有些问题，，所以本人做了一些修改，使他能够跑起来。

1.  打开VS2010(其他的版本也可以).

2.  文件->新建项目.

3.  选择c#控制台项目.

4.  命名项目为 ReallyReallyRealySimpleRogueLike.

5. 右键引用->添加引用.

6. 点击.net,选择System.Drawing.

7. 在Program.cs 的最上面添加using System.Drawing.

8. 将Program.cs里的代码改为以下这样:

class Program{static void Main(string[] args){Dungeon dungeon = new Dungeon(Constants.DungeonWidth, Constants.DungeonHeight);string displayText = Constants.IntroductionText;while (dungeon.IsGameActive){dungeon.DrawToConsole();Console.WriteLine(displayText);Console.Write(Constants.CursorImage);displayText = dungeon.ExecuteCommand(Console.ReadKey());}Console.WriteLine(ConcludeGame(dungeon));Console.ReadLine();}private static string ConcludeGame(Dungeon dungeon){return (dungeon.player.Hits > 0) ? Constants.PlayerWinsText : Constants.MonsterWinsText;}}

9.  添加一个Dungeon类:

class Dungeon{Random r;public Player player;List monsters;List swords;List walls;public Tile[,] Tiles;private int xMax;private int yMax;public enum Direction{North,South,East,West}public bool IsGameActive{get{return (player.Hits > 0 && monsters.Any(m => m.Hits > 0));}}public Dungeon(int xMax, int yMax){monsters = new List();walls = new List();swords = new List();this.xMax = xMax;this.yMax = yMax;Tiles = new Tile[xMax, yMax];BuildRandomDungeon();SetDungeonTiles();}public string ExecuteCommand(ConsoleKeyInfo command){string commandResult = ProcessCommand(command);ProcessMonsters();SetDungeonTiles();return commandResult;}private void ProcessMonsters(){if (monsters != null && monsters.Count > 0){monsters.Where(m => m.Hits >= 0).ToList().ForEach(m =>{MoveMonsterToPlayer(m);});}}private void MoveMonsterToPlayer(Monster monster){if (player.X != monster.X){if (player.X > monster.X){monster.X++;}else{monster.X--;}}else if (player.Y != monster.Y){if (player.Y > monster.Y){monster.Y++;}else{monster.Y--;}}else{ResolveCombat(monster);}}private void BuildRandomDungeon(){r = new Random();SetAllDungeonSquaresToTiles();for (int i = 0; i < xMax; i++){Wall top = new Wall(i, 0);walls.Add(top);Wall bottom = new Wall(i, yMax - 1);walls.Add(bottom);}for (int i = 0; i < yMax; i++){Wall left = new Wall(0, i);walls.Add(left);Wall right = new Wall(xMax - 1, i);walls.Add(right);}for (int i = 0; i < Constants.NumberOfSwords; i++){Sword s = new Sword(GetValidRandomPoint());swords.Add(s);}for (int i = 0; i < Constants.NumberOfMonsters; i++){Monster m = new Monster(GetValidRandomPoint());monsters.Add(m);}player = new Player(GetValidRandomPoint());}private void ResolveCombat(Monster monster){if (player.Inventory.Any()){monster.Die();}else{player.Die();}}private Point GetValidRandomPoint(){Point p=new Point(r.Next(1,xMax-1), r.Next(1,yMax-1));while(Tiles[p.X,p.Y].ImageCharacter!=Constants.TileImage){p = new Point(r.Next(1,xMax-1), r.Next(1,yMax-1));}return p;}public string ProcessCommand(ConsoleKeyInfo command){string output = string.Empty;switch (command.Key){case ConsoleKey.UpArrow:case ConsoleKey.DownArrow:case ConsoleKey.RightArrow:case ConsoleKey.LeftArrow:output = GetNewLocation(command, new Point(player.X, player.Y));break;case ConsoleKey.F1:output = Constants.NoHelpText;break;}return output;}private string GetNewLocation(ConsoleKeyInfo command, Point move){switch (command.Key){case ConsoleKey.UpArrow:move.Y -= 1;break;case ConsoleKey.DownArrow:move.Y += 1;break;case ConsoleKey.RightArrow:move.X += 1;break;case ConsoleKey.LeftArrow:move.X -= 1;break;}if (!IsInvalidValidMove(move.X, move.Y)){player.X = move.X;player.Y = move.Y;if (Tiles[move.X, move.Y] is Sword && player.Inventory.Count == 0){Sword sword = (Sword)Tiles[move.X, move.Y];player.Inventory.Add(sword);swords.Remove(sword);}return Constants.OKCommandText;}elsereturn Constants.InvalidMoveText;}public bool IsInvalidValidMove(int x, int y){return (x == 0 || x == Constants.DungeonWidth - 1 || y == Constants.DungeonHeight - 1 || y == 0);}public void SetDungeonTiles(){//Draw the empty dungeonSetAllDungeonSquaresToTiles();SetAllDungeonObjectsToTiles();}private void SetAllDungeonObjectsToTiles(){//Now draw each of the parts of the dungeonwalls.ForEach(w => Tiles[w.X, w.Y] = w);swords.ForEach(s => Tiles[s.X, s.Y] = s);monsters.ForEach(m => Tiles[m.X, m.Y] = m);Tiles[player.X, player.Y] = player;}private void SetAllDungeonSquaresToTiles(){for (int i = 0; i < yMax; i++){for (int j = 0; j < xMax; j++){Tiles[j, i] = new Tile(i, j);}}}public void DrawToConsole(){Console.Clear();for (int i = 0; i < yMax; i++){for (int j = 0; j < xMax; j++){Console.ForegroundColor = Tiles[j, i].Color;Console.Write(Tiles[j, i].ImageCharacter);}Console.WriteLine();}}}

10.  添加一个Tile类,在这个cs文件里，有wall和sword类:

public class Tile{public string name { get; set; }public string ImageCharacter { get; set; }public ConsoleColor Color { get; set; }public int X { get; set; }public int Y { get; set; }public Tile() { }public Tile(int x, int y): base(){this.X = x;this.Y = y;ImageCharacter = Constants.TileImage;Color = Constants.TileColor;}}public class Wall : Tile{public Wall(int x, int y): base(x, y){ImageCharacter = Constants.WallImage;this.Color = Constants.WallColor;}}public class Sword : Tile{public Sword(Point p){ImageCharacter = Constants.SwordImage;this.Color = Constants.SwordColor;X = p.X;Y = p.Y;}}

public class Creature : Tile{public int Hits { get; set; }public void Die(){Hits = 0;}}public class Player : Creature{public Player(Point p){ImageCharacter = Constants.PlayerImage;Color = Constants.PlayerColor;Inventory = new List();X = p.X;Y = p.Y;Hits = Constants.StartingHitPoints;}public List Inventory { get; set; }}public class Monster : Creature{public Monster(Point p){ImageCharacter = Constants.MonsterImage;Color = Constants.MonsterColor;X = p.X;Y = p.Y;Hits = Constants.StartingHitPoints;}}

public static class Constants{public readonly static int DungeonHeight = 20;public readonly static int DungeonWidth = 20;public readonly static int NumberOfSwords = 5;public readonly static int MonsterDamage = 2;public readonly static int NumberOfMonsters = 1;public readonly static int StartingHitPoints = 10;public readonly static string TileImage = ".";public readonly static string WallImage = "#";public readonly static string PlayerImage = "@";public readonly static string SwordImage = "s";public readonly static string StepsImage = "S";public readonly static string MonsterImage = "M";public readonly static string CursorImage = ">";public readonly static ConsoleColor MonsterColor = ConsoleColor.Blue;public readonly static ConsoleColor PlayerColor = ConsoleColor.Gray;public readonly static ConsoleColor WallColor = ConsoleColor.DarkCyan;public readonly static ConsoleColor SwordColor = ConsoleColor.Yellow;public readonly static ConsoleColor TileColor = ConsoleColor.White;public readonly static string InvalidCommandText = "That is not a valid command";public readonly static string OKCommandText = "OK";public readonly static string InvalidMoveText = "That is not a valid move";public readonly static string IntroductionText = "Welcome to the dungeon - grab a sword kill the monster(s) win the game";public readonly static string PlayerWinsText = "Player kills monster and wins";public readonly static string MonsterWinsText = "Monster kills player and wins";public readonly static string NoHelpText = "No help text";}
