??????身為漫威迷，最近又把《鋼鐵俠》和《復仇者聯盟》系列又重溫了一遍，真的是印證了那句話：“讀書百遍，其意自現”。看電影一個道理，每看一遍，都有不懂的感受~ 不知道大伙是不是也有同樣的感受，對于好的電影，真的是回味無窮！

---

?????本篇博文也是因《復仇者聯盟1》的啟發，C#語言實現的一個小游戲，所以游戲命名就叫“鋼鐵俠VS太空侵略者》了！

???? 先上一個游戲原型圖：

??????Talk is Cheap，Show me the Code!

?????? 代碼方面沒有太難的操作，主要依賴于Timer控件：

?????分別用來監控游戲中Iron man 子彈移動，侵略者左右移動，往下移動，侵略者子彈移動，子彈碰撞，以及觀察者監控(主要校驗生命值)，具體代碼如下：

????? ?侵略者界面生成：

private void CreateControl(Form p){ PictureBox pb = new PictureBox(); pb.Location = new Point(x, y); pb.Size = new Size(width, height); pb.BackgroundImage = Properties.Resources.invader; pb.BackgroundImageLayout = ImageLayout.Stretch; pb.Name = "Alien"; p.Controls.Add(pb); }public void CreateSprites(Form p){ for(int i = 0; i < rows; i++) { for(int j = 0; j < columns; j++) { CreateControl(p); x += width + space; } y += height + space; x = 150; }}

???????鍵盤事件綁定：

private void Pressed(object sender, KeyEventArgs e){ if (e.KeyCode == Keys.A || e.KeyCode == Keys.Left) { moveLeft = true; } else if (e.KeyCode == Keys.D || e.KeyCode == Keys.Right) { moveRight = true; } else if (e.KeyCode == Keys.Space && game && !fired) { Missile(); fired = true; }}private void Released(object sender, KeyEventArgs e){ if (e.KeyCode == Keys.A || e.KeyCode == Keys.Left) { moveLeft = false; } else if (e.KeyCode == Keys.D || e.KeyCode == Keys.Right) { moveRight = false; } else if (e.KeyCode == Keys.Space) { fired = false; }}

????? ?Iron man 左右移動：

private void PlayerMove(object sender, EventArgs e) { if (moveLeft && Player.Location.X >= 0) { Player.Left--; } else if (moveRight && Player.Location.X <= limit) { Player.Left++; } }

????? ?子彈發射：

private void FireBullet(object sender, EventArgs e){ foreach (Control c in this.Controls) { if (c is PictureBox && c.Name == "Bullet") { PictureBox bullet = (PictureBox)c; bullet.Top -= 5; if (bullet.Location.Y <= 0) { this.Controls.Remove(bullet); } foreach(Control ct in this.Controls) { if (ct is PictureBox && ct.Name == "Laser") { PictureBox laser = (PictureBox)ct; if (bullet.Bounds.IntersectsWith(laser.Bounds)) { this.Controls.Remove(bullet); this.Controls.Remove(laser); pts++; Score(pts); } } } foreach(Control ctrl in this.Controls) { if (ctrl is PictureBox && ctrl.Name == "Alien") { PictureBox alien = (PictureBox)ctrl; if (bullet.Bounds.IntersectsWith(alien.Bounds) && !Touched(alien)) { this.Controls.Remove(bullet); this.Controls.Remove(alien); aliens.Remove(alien); pts += 5; Score(pts); CheckForWinner(); } else if (bullet.Bounds.IntersectsWith(alien.Bounds) && Touched(alien)) { this.Controls.Remove(bullet); this.Controls.Remove(alien); delay.Add(alien); pts += 5; Score(pts); CheckForWinner(); } } } } }}

????? ?子彈

private void Missile(){ PictureBox bullet = new PictureBox(); bullet.Location = new Point(Player.Location.X + Player.Width / 2, Player.Location.Y - 20); bullet.Size = new Size(5, 20); bullet.BackgroundImage = Properties.Resources.bullet; bullet.BackgroundImageLayout = ImageLayout.Stretch; bullet.Name = "Bullet"; this.Controls.Add(bullet);}

????? ?侵略者移動：

private void AlienMove(){ foreach(PictureBox alien in aliens) { alien.Location = new Point(alien.Location.X + left, alien.Location.Y + top); SetDirection(alien); Collided(alien); }}private void Collided(PictureBox a){ if (a.Bounds.IntersectsWith(Player.Bounds)) { gameOver(); }}

????? ?子彈移動效果：

private void Beam(PictureBox a){ PictureBox laser = new PictureBox(); laser.Location = new Point(a.Location.X + a.Width / 3, a.Location.Y + 20); laser.Size = new Size(5, 20); laser.BackgroundImage = Properties.Resources.laser; laser.BackgroundImageLayout = ImageLayout.Stretch; laser.Name = "Laser"; this.Controls.Add(laser);}private void StrikeSpan(object sender, EventArgs e){ Random r = new Random(); int pick; if (aliens.Count > 0) { pick = r.Next(aliens.Count); Beam(aliens[pick]); }}private void DetectLaser(object sender, EventArgs e){ foreach(Control c in this.Controls) { if (c is PictureBox && c.Name == "Laser") { PictureBox laser = (PictureBox)c; laser.Top += 5; if (laser.Location.Y >= limit) { this.Controls.Remove(laser); } if (laser.Bounds.IntersectsWith(Player.Bounds)) { this.Controls.Remove(laser); LoseLife(); } } }}

????????主要核心代碼如上，下面看下運行效果圖：
