模仿坦克大战源码

项目描述
C#编写的一个坦克大战游戏
用键盘的上下左右可以控制坦克的移动，
空格键是开炮，打坏一个坦克得100分。
游戏很有意思，也很值得我们学习。
欢迎感兴趣的用户下载学习。

主要代码：
private void Form1_KeyDown(object sender, KeyEventArgs e)
        {
            switch (e.KeyCode)
            {
                case Keys.Up: //上
                    if (MyTank.Top == 0 || Map[MyTank.Left, MyTank.Top - 1] == 1
                        || Meet_Tank(MyTank.Left, MyTank.Top - 1)) //遇到墙砖或坦克
                        ; //不动
                    else if (MyTank.Direct == 0) MyTank.Top--;
                    MyTank.Direct = 0;
                    break;
                case Keys.Down: //下
                    if (MyTank.Top == 9 || Map[MyTank.Left, MyTank.Top + 1] == 1
                        || Meet_Tank(MyTank.Left, MyTank.Top + 1)) //遇到墙砖或坦克
                        ; //不动
                    else if (MyTank.Direct == 1) MyTank.Top++;
                    MyTank.Direct = 1;
                    break;

                case Keys.Left: //左
                    if (MyTank.Left == 0 || Map[MyTank.Left - 1, MyTank.Top] == 1
                        || Meet_Tank(MyTank.Left - 1, MyTank.Top)) //遇到墙砖或坦克
                        ; //不动
                    else if (MyTank.Direct == 2) MyTank.Left--;
                    MyTank.Direct = 2;
                    break;
                case Keys.Right: //右
                    if (MyTank.Left == 9 || Map[MyTank.Left + 1, MyTank.Top] == 1
                        || Meet_Tank(MyTank.Left + 1, MyTank.Top)) //遇到墙砖或坦克
                        ; //不动
                    else if (MyTank.Direct == 3) MyTank.Left++;
                    MyTank.Direct = 3;
                    break;
                case Keys.Space: //空格发射子弹
                    MyTank.fire();
                    break;
            }
            pictureBox1.Invalidate(); //重画游戏面板区域
            lblX.Text = "X坐标：" + MyTank.Left + "  Y坐标：" + MyTank.Top;
        }
