    enum rocks
    {
        uno = 1,
        dos,
        tres 

    }

だから私は一番上に私の列挙型を宣言します、

rocks[] values = {rocks.uno, rocks.dos, rocks.tres};
        Random random = new Random();
        rocks randomValue = values[random.Next(values.Length)];

乱数ジェネレーターを初期化する

private void drawUno(SpriteBatch spriteBatch)
    {
        spriteBatch.Draw(rock1, Vector2.Zero, Color.White);
    }

それぞれの岩を描くための別々の方法があります

 public void drawRocks(SpriteBatch spriteBatch)
    {
        switch (Rocks)
        {
            case rocks.uno:
                drawUno(spriteBatch);
                break;
            case rocks.dos:
                drawDos(spriteBatch);
                break;
            case rocks.tres:
                drawTres(spriteBatch);
                break;
            default:
                break;
        }
    }

ランダムが生成する岩を引き出す方法

メインの描画メソッドでdrawRockをコールバックしましたが、何も表示されません。何が間違っているのでしょうか。

私はあなたが何かを忘れたと思います。あなたはランダムな岩を選んでいます：

rocks randomValue = values[random.Next(values.Length)];

次に、randomValue をまったく使用しません。代わりRocksに、switch ステートメントで使用しています。

switch (Rocks)
{
    case rocks.uno:
        drawUno(spriteBatch);
        break;
    case rocks.dos:
        drawDos(spriteBatch);
        break;
    case rocks.tres:
        drawTres(spriteBatch);
        break;
    default:
        break;
}

したがってrandomValue、スイッチで使用するか、ランダムな値をRocksプロパティに割り当てます。

SpriteBatch で Begin および End 呼び出しを行っていません。これらは、画面に表示するために必要です。こちらのドキュメントをご覧ください。このことを明確に述べています。
