XNAランダムタイル地形

Question

私はちょっとしたゲームに取り組んでいますが、ほとんどの場合は楽しいですが、ちょっとしたものに遭遇しました。このアルゴリズムを使うたびにランダムな地形を生成しようとしています。ノッチのミニクリップソース私は信じている。誰も私を助けることができる場合

、病気

私の問題は、私は画面にこれを描くか、画面

にそれを描画するテクスチャ2Dとして保存する方法を本当のアイデアを持っていないということです非常に感謝します

なぜコードの一部についてコメントしましたか？

あなただけの画像でそれを置くことができるようにしたい場合は、あなたが行うことができます：

System.Drawing.Image yourNewMap; 

using (MemoryStream ms = new MemoryStream(myByteArray,0,myByteArray.Length)) 
{  
    ms.Write(myByteArray,0,myByteArray.Length);  
    yourNewMap = Image.FromStream(ms,true);  
} 

それとも、クラスにすべてこのコードを追加することで、クラスには、このコンソールアプリケーションを変換し、追加することができますイメージを返す静的メソッド：

public static Image getRandomMap() 
{ 
    int d = 0; 
    int w = 128; 
    int h = 128; 
    byte[] map = LevelGen.createAndValidateTopMap(w, h)[0]; 



    int w = 128; 
    int h = 128; 

    byte[] map = LevelGen.createAndValidateTopMap(w, h)[0]; 
    byte[] map = LevelGen.createAndValidateUndergroundMap(w, h, (d++ % 3) + 1)[0]; 
    byte[] map = LevelGen.createAndValidateSkyMap(w, h)[0]; 

    int[] pixels = new int[w * h]; 
    for (int y = 0; y < h; y++) 
    { 
     for (int x = 0; x < w; x++) 
     { 
      int i = x + y * w; 

     // if (map[i] == Tile.water.id) pixels[i] = 0x000080; 
      if (map[i] == Tile.Dirt.id) pixels[i] = 0x604040; 
      if (map[i] == Tile.Sand.id) pixels[i] = 0xa0a040; 
     } 
    } 

    System.Drawing.Image yourNewMap; 

    using (MemoryStream ms = new MemoryStream(myByteArray,0,myByteArray.Length)) 
    {  
     ms.Write(myByteArray,0,myByteArray.Length);  
     yourNewMap = Image.FromStream(ms,true);  
    } 

    return yourNewMap; 

} 

あなたのゲームからあなたのイメージを取得することができます。

Image myMap = Tile_Engine.Game.getRandomMap(); 

まだ、コードの一部がコメントとしてマークされている理由はわかりません。
