C#小游戏—钢铁侠VS太空侵略者

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(); }                    }}
}
