Question

我在使用C＃制作游戏时遇到问题它是这样的：我制作了一个用计时器弹跳的图片盒，然后我想要做的是当我点击它时标签将“点数：”变为“点数：1”但它会像“点数：”一样“积分：162”。

我认为这是因为间隔，我无法弄清楚如何解决。

- 我们点击图片 -points加1 * 尚未完成 -image（picturebox）desapear - 随机添加另一张图片（图片框）

我想有一个点计数器，但是使用计时器，就是它。任何帮助都会被贬低。

 int dx;
    int dy;
    int x;
    int y;
    int pts = 0;

    private void Form1_Load(object sender, EventArgs e)
    {
        Random rnd = new Random();
        dx = rnd.Next(2, 5);
        dy = rnd.Next(2, 5);
        x = rnd.Next(0, this.ClientSize.Width - 1 );
        y = rnd.Next(0, this.ClientSize.Height - 1);
    }

    private void Form1_Paint(object sender, PaintEventArgs e)
    {
        pictureBox1.Location = new Point(x, y);
        pictureBox1.Click += pictureBox1_Click;
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        x += dx;
        if (x < 0)
        {
            dx = -dx;
        }
        else if (x + 50 > this.ClientSize.Width)
        {
            dx = -dx;
        }

        y += dy;
        if (y < 100)
        {
            dy = -dy;
        }
        else if (y + 50 > this.ClientSize.Height)
        {
            dy = -dy;
        }
        this.Invalidate();
    } 

    void pictureBox1_Click(object sender, EventArgs e)
    {  
       pts++;
       label1.Text = "Pontos: " + pts;

       pictureBox1.Location = new Point(x,y); 
    }

Answer 1

代码不完整。请指定哪个甚至，你正在触发Timer事件，这导致调用“timer1_Tick”方法。

查看问题和代码，我认为每个Timer“Click”都会导致重绘窗口。更好的方法是仅在Click of Picture上重新绘制窗口。此外，似乎与每个Time_Click在相同的序列中，您也调用Picture_Click（代码不在发布的代码中......但根据行为猜测），这会导致增加点数。所以，一旦这个结束，可能有162个蜱，这就是为什么你看到162分。

Answer 2

每次调用Form1_Paint

时，您似乎都在订阅点击事件

 pictureBox1.Click += pictureBox1_Click;

尝试将其移至构造函数或初始化方法。
