Question

有没有办法，我怎样才能让程序在每次分数增加 1 时将障碍速度增加 1？ （包含所有 if 语句的部分）。 我认为它一定是某种 for 循环，但也许我都错了。 希望有人可以提供帮助。

我是编码新手，所以如果你能像孩子一样解释它会很棒

我的程序：

namespace Arnold
{
    public partial class Form1 : Form
    {
        bool jumping = false;
        int jumpSpeed;
        int force = 15;
        int score = 0;
        int obstacleSpeed = 15;
        Random rand = new Random();
        int posisition;
        bool isGameOver = false;

 public Form1()
        {
            InitializeComponent();
            GameReset();
        }

        private void mainGameTimerEvent(object sender, EventArgs e)
        {
            player.Top += jumpSpeed;

            txtScore.Text = "score: " + score;

            if (jumping == true && force < 0)
            {
                jumping = false;
            }

            if (jumping == true)
            {
                jumpSpeed = -25;
                force -= 1;
            }
            else
            {
                jumpSpeed = 25;
            }

            if (player.Top > 364 && jumping == false)
            {

                player.Top = 365;

            }

                }
            }

            gameTimer.Start();

        }


    }
}

它告诉我要添加更多详细信息，因此下一部分只是垃圾邮件。 对不起。

Answer 1

这是实现这一点的方法。 它只使用创建一个引用我命名为OnScoreChanged()的方法的get-set property 。

int _score;
int speed;
private int score
{
    get
    {
        return _score;
    }
    set
    {
        _score = value;
        OnScoreChanged();
    }
}

并且您的 OnScoreChanged() 方法可以支持速度的变化。

private void OnScoreChanged()
{
    speed++;
}

请注意，只要您更改score的值，就会调用此事件。 为了避免在score下降时提高speed ，您可以执行以下操作：

private int score
{
    get
    {
        return _score;
    }
    set
    {
        if(_score < value)  // When the value of score increases
        {
            OnScoreIncreased();
        }
        else if(_score > value) // When the value of score decreases
        {
            OnScoreDecreased();
        }
        else
        {
            _score = value;
        }
    }
}
