我最近才决定我应该尝试做一个基于瓷砖的小“游戏”。我按照 YouTube 上 Nick Gravelyn 和 ouyyu91 的教程进行操作，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东西，我不太关心架构）
游戏类：

spriteBatch = new SpriteBatch(GraphicsDevice);
graphics.PreferredBackBufferWidth = 800;
graphics.PreferredBackBufferHeight = 600;
Texture2D tex_Air = Content.Load<Texture2D>("Tiles/tex_air");

// 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;

#if WINDOWS || XBOX
public static class Program
{
public static List<Texture2D> Tiles = new List<Texture2D>();
/// <summary>
/// The main entry point for the application.

static void Main(string[] args)
{
MainGame Game = new MainGame();
Game.Run();
}
}
#endif
}
请帮忙！我不想听起来像我只是在这里，所以你可以调试我的代码，但我真的没有进一步......
