我的子弹射击算法有问题

我正在制作一个游戏，我有一个射击子弹的功能，一个玩家可以得到10发子弹。这就是现在的样子：

private void Form1_MouseDown(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Left)
    {
        bullets.Add(new Bullet(robot.RobotRec));
        Bullet -= 1;// lose a life
        lblBullet.Text = Bullet.ToString();// display number of lives
        checkBullet();
    }
}
private void pnlGame_MouseDown(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Left)
    {
        bullets.Add(new Bullet(robot.RobotRec));
        Bullet -= 1;// lose a life
        lblBullet.Text = Bullet.ToString();// display number of lives
        checkBullet();
    }
}
private void checkBullet()
{
    if (Bullet == 0)
    {
        tmrShoot.Enabled = false;
    }
}

但在子弹数为零后，我仍然可以射杀他们，尽管他们不会影响任何事情。好的，他们刚刚通过的分数，但我想禁用子弹图像。所以我在想：你能禁用mousedown吗？做这件事的代码是什么？

您正在检查Bullet==0是否错误，它应该更像这样：

private void Form1_MouseDown(object sender, MouseEventArgs e)
{
    if (Bullet == 0)
    {
        tmrShoot.Enabled = false;
        return; //leaves the method and followup code doesnt run
    }
    if (e.Button == MouseButtons.Left)
    {
        bullets.Add(new Bullet(robot.RobotRec));
        Bullet -= 1;// lose a life
        lblBullet.Text = Bullet.ToString();// display number of lives
    }
}
private void pnlGame_MouseDown(object sender, MouseEventArgs e)
{
    if (Bullet == 0)
    {
        tmrShoot.Enabled = false;
        return; //leaves the method and followup code doesnt run
    }
    if (e.Button == MouseButtons.Left)
    {
        bullets.Add(new Bullet(robot.RobotRec));
        Bullet -= 1;// lose a life
        lblBullet.Text = Bullet.ToString();// display number of lives
    }
}

这将防止创建项目符号并计算addional-1。

你也可以在一个方法中减少MouseDown事件的整个代码，比如

private void Form1_MouseDown(object sender, MouseEventArgs e)
{
    FireBullet(e);
}
private void pnlGame_MouseDown(object sender, MouseEventArgs e)
{
    FireBullet(e);
}
private void FireBullet(MouseEventArgs e)
{
        if (Bullet == 0)
        {
            tmrShoot.Enabled = false;
            return; //leaves the method and followup code doesnt run
        }
        if (e.Button == MouseButtons.Left)
        {
            bullets.Add(new Bullet(robot.RobotRec));
            Bullet -= 1;// lose a life
            lblBullet.Text = Bullet.ToString();// display number of lives
        }
}

或者在Form1和你的pnlGame上注册相同的MouseDown事件：

//In FormLoad
Form1.MouseDown += FireBullet_MouseDown;
pnlGame.MouseDown += FireBullet_MouseDown;
private void FireBullet_MouseDown(object sender, MouseEventArgs e)
{
        if (Bullet == 0)
        {
            tmrShoot.Enabled = false;
            return; //leaves the method and followup code doesnt run
        }
        if (e.Button == MouseButtons.Left)
        {
            bullets.Add(new Bullet(robot.RobotRec));
            Bullet -= 1;// lose a life
            lblBullet.Text = Bullet.ToString();// display number of lives
        }
}
