身为漫威迷，最近又把《钢铁侠》和《复仇者联盟》系列又重温了一遍，真的是印证了那句话：“读书百遍，其意自现”。看电影一个道理，每看一遍，都有不懂的感受~ 不知道大伙是不是也有同样的感受，对于好的电影，真的是回味无穷！
本篇博文也是因《复仇者联盟1》的启发，C#语言实现的一个小游戏，所以游戏命名就叫“钢铁侠VS太空侵略者》了！
先上一个游戏原型图：
Talk is Cheap，Show me the Code!
代码方面没有太难的操作，主要依赖于Timer控件：
分别用来监控游戏中Iron man 子弹移动，侵略者左右移动，往下移动，侵略者子弹移动，子弹碰撞，以及观察者监控(主要校验生命值)，具体代码如下：
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;}}
键盘事件绑定：
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 左右移动：
private void PlayerMove(object sender, EventArgs e) {if (moveLeft && Player.Location.X >= 0){Player.Left--;}else if (moveRight && Player.Location.X <= limit){Player.Left++;} }
子弹发射：
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();}} } } }}
子弹
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);}
侵略者移动：
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(); }}
子弹移动效果：
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(); } } }}
