我正在尝试使用C#(Windows窗体)制作迷你游戏,例如太空入侵者。飞船飞行得很好,但是我没有得到多发射击,我有一种制作动画的方法timer_Tick,当我按下太空进行射击时,第一发可以正常工作,但是第二发可以。此半位置的第一杆消失。镜头是pictureBox,我尝试了pictureBox列表,但没有成功。

我有这样的事情:

    public void Form1_Load(object sender, EventArgs e)
    {
        shootP = new PictureBox();
        shootP.Image = Properties.Resources.shoot_1;
        shootP.SizeMode = PictureBoxSizeMode.Zoom;
        shootP.Size = new Size(10, 72);
        ListShoot = new List<PictureBox>();
        int i = -1;
    }
     private void Form1_KeyDown(object sender, KeyEventArgs e)
     {

        if (e.KeyCode == Keys.Space)
        {
        control = false;
        i++;
        ListShoot.Add(shootP);
        timeShoot.Start();
     }

      private void timeShoot_Tick(object sender, EventArgs e)
      {
        if (control == false)
        {
            ListShoot[i].Location = new Point(spacecraft._imageBox.Location.X + 50, spacecraft._imageBox.Location.Y - 55);  // align the shoot with spacecraft
            control = true;
        }

            ListShoot[i].Top -= 40;
      }


我究竟做错了什么?

最佳答案

您每次都需要创建一个新图像,就像aliasesce的答案一样。

private void Form1_KeyDown(object sender, KeyEventArgs e)
 {
    if (e.KeyCode == Keys.Space)
    {
      control = false;
      shootP = new PictureBox();
      shootP.Image = Properties.Resources.shoot_1;
      shootP.SizeMode = PictureBoxSizeMode.Zoom;
      shootP.Size = new Size(10, 72);
      ListShoot.Add(shootP);
      timeShoot.Start();
    }
 }


然后,您需要更新列表中所有图像的位置。使用foreach循环并放弃int迭代器。

private void timeShoot_Tick(object sender, EventArgs e)
  {
    if (control == false)
    {
       foreach PictureBox shot in ListShot
       {
           shot.Location = new Point(spacecraft._imageBox.Location.X + 50, spacecraft._imageBox.Location.Y - 55);  // align the shoot with spacecraft
           shot.Top -= 40;
       }
       control = true;
    }
  }


您可能还必须更新绘制图像的代码,以使其遍历列表。与类似:

foreach PictureBox shot in ListShoot
{
   draw(shot);
}


最后,您可能需要不时地清理列表,以消除屏幕上不再存在的不再需要更新或绘制的镜头。
