Question

我正在使用LoadContent方法创建一个二十一点纸牌游戏。我正在挑选一张随机卡，但问题是我不知道如何正确地结束这种方法，以便它将选择一张随机卡而不是无限循环。现在有2张随机卡因无限循环而闪烁。

public class Kaart
{

    public Vector2 asukoht = new Vector2(0, 0);

    public List<Texture2D> tekstuur = new List<Texture2D>();


    Random  rand = new Random();


    public void loadContent(ContentManager manager) // loading first card
    {

        for (int j = 3; j < 7; j++)
        {


                tekstuur.Add(manager.Load<Texture2D>("Risti" + j.ToString()));


        }
    }
    public void loadContent2(ContentManager manager) // loading second card
    {

        for (int j = 3; j < 7; j++)
        {                

                tekstuur.Add(manager.Load<Texture2D>("Risti" + j.ToString()));


               }

    }

    public void Draw(SpriteBatch sprite) // here ill draw the random card
    {

        sprite.Draw(tekstuur[rand.Next(tekstuur.Count)], asukoht, Color.White);
        sprite.Draw(tekstuur[rand.Next(tekstuur.Count)], asukoht, Color.White);

    }

}

在xna中，您有4种主要方法：

loadContent＆lt; - 每次运行游戏时都应执行一次，在这里加载游戏内容，纹理等。

初始化＆lt; - 此方法也只会执行一次，在这里您可以设置游戏分辨率，抗锯齿和音频选项的额外配置等。

更新＆lt; - 这将每秒执行60次，在这里你必须计算一个角色是否死亡或你是否用完了hp

draw＆lt; - 在每次更新方法之后，将调用draw，在这里你将绘制当前的游戏对象，比如向上或向下移动一个角色，使某些东西浮动等等。

考虑到这一点，请移动您的代码（重构它），它应该可以正常工作，如果您有任何其他问题，请告诉我。

此外，当你执行rand.Next(tekstuur.Count)时，你应该做+1，因为随机会给你一个介于0和你指定的上限之间的数字，比如你在那里给它5，它会返回你的数字最多4个而且从不5个......所以你错过了一个“tekstuur”
