Question

我最近决定尝试做一个基于平铺的“游戏”。我跟着来自YouTube的Nick Gravelyn和ouyyu91的教程，无论我做什么，它一直告诉我Map.Coords的索引超出范围。（我希望你能从这段代码中读到一些内容，我并不太关心架构）

游戏类：

        SpriteBatch spriteBatch;



        TileMap Map = new TileMap("Daniel", "Beastiality 1", "1/EASY");
        int TileWidth, TileHeight;

        public MainGame()
        {
            graphics = new GraphicsDeviceManager(this);
            Content.RootDirectory = "Content";
        }

            // Create a new SpriteBatch, which can be used to draw textures.
            spriteBatch = new SpriteBatch(GraphicsDevice);


            graphics.PreferredBackBufferWidth = 800;
            graphics.PreferredBackBufferHeight = 600;

            Texture2D tex_Air = Content.Load<Texture2D>("Tiles/tex_air");
            Texture2D tex_Ground = Content.Load<Texture2D>("Tiles/tex_ground");
            Texture2D tex_Wall = Content.Load<Texture2D>("Tiles/tex_wall");
            Texture2D tex_Celldoor = Content.Load<Texture2D>("Tiles/tex_celldoor");
            Texture2D tex_Woodenchest = Content.Load<Texture2D>("Tiles/tex_woodenchest");

            Program.Tiles.Add(tex_Air);
            Program.Tiles.Add(tex_Ground);
            Program.Tiles.Add(tex_Wall);

            TileWidth = graphics.PreferredBackBufferWidth / 50;
            TileHeight = TileWidth;

            Map.Coords = new int[,]
            {

                {2,2,2,2,2,2,2,0,0,0},
                {2,0,0,4,0,0,2,0,0,0},
                {2,0,0,0,0,0,2,0,0,0},

                {2,0,0,0,0,0,2,0,0,0},
                {0,0,0,0,0,0,0,0,0,0},
                {0,0,0,0,0,0,0,0,0,0},
                {0,0,0,0,0,0,0,0,0,0},
                {0,0,0,0,0,0,0,0,0,0},

            };
            Map.Width = Map.Coords.GetLength(1);
            Map.Height = Map.Coords.GetLength(0);







            // TODO: use this.Content to load your game content here
        }

        /// <summary>

                this.Exit();

            // TODO: Add your update logic here

            base.Update(gameTime);
        }

        /// <summary>

        protected override void Draw(GameTime gameTime)
        {
            GraphicsDevice.Clear(Color.CornflowerBlue);

            // TODO: Add your drawing code here


            spriteBatch.Begin();

            for (int x = 0; x < Map.Coords.GetLength(1); x++)
            {

                for (int y = 0; y < Map.Coords.GetLength(0); y++)
                {
                    Rectangle indexRect = new Rectangle(x * TileWidth, y * TileHeight, TileWidth, TileHeight);
                    int Index = Map.Coords[x,y];//Heres the Error!
                    Texture2D tex = Program.Tiles[Index];
                    Tile tile = new Tile(tex, indexRect);
                    spriteBatch.Draw(Program.Tiles[1], indexRect , Color.White);
                    tile.Draw(spriteBatch);




                }

            }






            spriteBatch.End();







            base.Draw(gameTime);
        }
    }
}

这是程序类......

using System;
using Microsoft.Xna.Framework.Graphics;
using System.Collections.Generic;

namespace Platformer
{
#if WINDOWS || XBOX
    public static class Program
    {
        public static List<Texture2D> Tiles = new List<Texture2D>();
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        static void Main(string[] args)
        {

            MainGame Game = new MainGame();
            Game.Run();

        }
    }
#endif
}

请帮忙！我不想听起来像我在这里，所以你可以调试我的代码，但我真的没有进一步...

我相信你的尺寸已经倒退了。它应该是

for (int x = 0; x < Map.Coords.GetLength(0); x++)
{
    for (int y = 0; y < Map.Coords.GetLength(1); y++)
    {
        int Index = Map.Coords[x,y];

或者这个：

for (int x = 0; x < Map.Coords.GetLength(1); x++)
{
    for (int y = 0; y < Map.Coords.GetLength(0); y++)
    {
        int Index = Map.Coords[y,x];

为什么指数超出范围？
