C#游戏《坦克大战》--主程序

今天和女朋友分手，写一段技术博客以平静心态。

1.统计信息

用于主界面显示各种信息

        //统计
        public struct t_statistics
        {
            public int generateenemyNum;   //生成敌人数量
            public int destroyenemyNum;    //已经摧毁的敌人数量
            public int GetcurrenemyNum()   //当前敌人数量
            {
                return generateenemyNum - destroyenemyNum;
            }
            public int GetremainingenemyNum()  //剩余的
            {
                return t_commpar.TANKNUMMAX - destroyenemyNum;
            }
            public void init()
            {
                generateenemyNum = 0;
                destroyenemyNum = 0;
            }
            public t_statistics(int g ,int d)
            {
                generateenemyNum = g;
                destroyenemyNum = d;
            }
        }

2.坦克序列

按一定的随机顺序生成各种坦克

        //生成序列，之后按此序列生成坦克
        void generaterandseq(int[] seq,  int len )
        {
            int i = 0;
            for (i = 0; i< len ;i++ )
            {
                seq[i] = (i%4)+1;
            }

            for (i = 0; i < len/2; i++)
            {
                int r = rn.Next(0, 9);
                if (r != i)
                {
                    mymath.swap(ref seq[i], ref  seq[r]);
                }
            }
            for (i = 0; i < len / 2; i++)
            {
                int r = rn.Next(0, 9);
                if (r != i)
                {
                    mymath.swap(ref seq[i + 10], ref  seq[r + 10]);
                }
            }
        }

        /// 

        /// 生成敌军坦克
        /// 
        /// 开始位置
        void generateEnemyTanks(Point startLocation)
        {
            tanks.Add(new tank(startLocation, randseq[randseqidx]  ));
       
            randseqidx++;
            if (randseqidx >= t_commpar.TANKNUMMAX) randseqidx = 0;

            dg_showtankcars += tanks[tanks.Count - 1].showtank;
            dg_showtankbullets += tanks[tanks.Count - 1].showbullet;
            tankacts.Add(tanks[tanks.Count - 1].tankact);

            statistics.generateenemyNum++;
            label_currenemynum.Text = statistics.GetcurrenemyNum().ToString();
        }

定义委托方便使用

        //委托
        internal delegate void _dg_showtank(ref Graphics gr);
        internal delegate void _dg_tankact( );

        _dg_showtank dg_showtankcars, dg_showtankbullets;

玩家坦克与保存所有坦克的列表。

3.摧毁坦克

        /// 

        /// 轮询所有敌军并摧毁需要的
        /// 
        void dowaitForDestroyTanks()
        {
            //  list注意删除顺序
            for (int i = tanks.Count - 1; i >= 0; i--)
            {
                if (tanks[i].aliveCnt > 0)
                {
                    tanks[i].aliveCnt--;
                    if (tanks[i].aliveCnt == 0)
                    {
                        destroyDestroyTanks(i);
                    }
                }
            }
        }

        //摧毁某个敌军
        void destroyDestroyTanks(int i)
        {
            statistics.destroyenemyNum++;
            label_destroyenemynum.Text = statistics.destroyenemyNum.ToString();
            label_currenemynum.Text = statistics.GetcurrenemyNum().ToString();
            label_remainingenemynum.Text = statistics.GetremainingenemyNum().ToString();

            tankacts.RemoveAt(i);
            dg_showtankbullets -= tanks[i].showbullet;
            dg_showtankcars -= tanks[i].showtank;
            tanks.RemoveAt(i);
        }

        //显示敌军被摧毁画面
        void showtankBedestroyed( tank tk )
        {
            tk.aliveCnt = t_commpar.TANKALIVECNTMAX;
            using (
            Graphics g = Graphics.FromImage(tk.currcarimg)
                )
            {
                g.DrawImage(bongimg, new Rectangle(0, 0, t_commpar.TANKSIZEX, t_commpar.TANKSIZEY));
            }
        }

4.主流程

游戏需要使用键盘进行操作，单独使用窗体的键盘事件是无法进行坦克的流畅操作。所有需要window API进行键盘状态读取。

        
        [DllImport("user32.dll", EntryPoint="GetKeyState")]
        public static extern int GetKeyState(int nVirKey);
        
        bool iskeySPACEPress()
        {
            return ((GetKeyState((int)(Keys.Space)) & 0x8000) != 0  );
        }
        bool iskeyUPPress()
        {
            return ((GetKeyState((int)(Keys.Up)) & 0x8000) != 0);
        }
        bool iskeyRIGHTPress()
        {
            return ((GetKeyState((int)(Keys.Right)) & 0x8000) != 0);
        }
        bool iskeyLEFTPress()
        {
            return ((GetKeyState((int)(Keys.Left)) & 0x8000) != 0);
        }

在定时读取键盘状态，操作坦克。

        //主流程15MS/per
        private void maintimer_Tick(object sender, EventArgs e)
        {
            updatatanksinfolist();
            playertank.tankact();
            for (int j = 0; j < tanks.Count; j++)
            {
                tankacts[j]( ); 
            }

            map.mainimg = mainimg;
            pbx_main.BackgroundImage = (Bitmap)mainimg.Clone();
            gr = Graphics.FromImage(pbx_main.BackgroundImage);
           
            int n = tanks.Count;
            for (var i = 0; i  0)
                    {
                        showplayerBeAttacted();
                    }
                    else { 
                    //END
                        showplayerBeAttacted();
                        playertank.isalive = false;
                    }
                }

                if ( tanks[i].isalive )
                    if ( playertank.bingo == tanks[i].uuid)//检测玩家是否打击中敌军
                    {
                        playertank.bingo = 0;
                        tanks[i].Hp -= playertank.Atk;
                        //每次重新加载避免音频丢失
                        if( ckb_shitmusic.Checked)
                        (new SoundPlayer(global::tank.Properties.Resources.tankbeattact)).Play();

                        if (tanks[i].Hp > 0)
                        { 
                            showtankinjured(i);
                        }
                        else
                        {
                            tanks[i].isalive = false;
                            showtankinjured(i);
                            showtankBedestroyed(tanks[i]);
                        }
                    }
            }

            dg_showtankbullets(ref gr);
            dg_showtankcars(ref gr);
        }
