作者：webabcd

介绍

使用 Silverlight 2.0(c#) 开发一个打苍蝇的游戏

玩法

用鼠标控制瞄准镜的移动，鼠标左键开火

在线DEMO

思路

1、苍蝇的移动轨迹用一个简单的公式计算，即正弦波。正弦波的公式：y = A * sin(ωx ＋ φ)

2、苍蝇控件使用MVP(Model - View - Presenter)模式开发，其目的只是为了说明如何在Silverlight中应用MVP模式

关键代码

1、苍蝇控件的Model

IFlyModel.cs


using System;


using System.Net;


using System.Windows;


using System.Windows.Controls;


using System.Windows.Documents;


using System.Windows.Ink;


using System.Windows.Input;


using System.Windows.Media;


using System.Windows.Media.Animation;


using System.Windows.Shapes;




namespace YYFly.Model


{


public interface IFlyModel


{


/// <summary>


/// 让一只苍蝇开始飞


/// </summary>


void Start();


/// <summary>


/// 让一只苍蝇停止飞


/// </summary>


void Stop();


/// <summary>


/// 计分方法


/// </summary>


void Score();




/// <summary>


/// 苍蝇改变位置所触发的事件


/// </summary>


event EventHandler<FlyEventArgs> FlyChanging;


}


}



FlyModel.cs


using System;


using System.Net;


using System.Windows;


using System.Windows.Controls;


using System.Windows.Documents;


using System.Windows.Ink;


using System.Windows.Input;


using System.Windows.Media;


using System.Windows.Media.Animation;


using System.Windows.Shapes;


using System.Windows.Threading;




namespace YYFly.Model


{


public class FlyModel : IFlyModel


{


private DispatcherTimer timer; // 改变苍蝇位置的计时器


private SineWave sineWave; // 苍蝇的运动轨迹（正弦波）的参数


private FlyEventArgs evt; // 苍蝇的位置参数


private Random random;


private double minX = -100, minY = 40, maxY = 300, minZ = 0.1, maxZ = 0.5;




private static readonly object objLock = new object();




public FlyModel()


{


timer = new DispatcherTimer();


timer.Tick += new EventHandler(timer_Tick);


timer.Interval = new TimeSpan(0, 0, 0, 0, 33);


}




void InitData()


{


random = new Random();




sineWave = new SineWave


{


A = random.Next(40, 60),


OffsetY = random.Next((int)minY, (int)maxY),


Omega = 1d / random.Next(20, 50),


Phi = random.Next((int)minX * 2, (int)minX),


};




evt = new FlyEventArgs()


{


X = minX,


Z = (minZ + maxZ) / 2,


Z_Out = Convert.ToBoolean(random.Next(0, 2))


};


}




void timer_Tick(object sender, EventArgs e)


{


evt.X += Singleton<Scorer>.Instance.Level * 1.5;


evt.Y = sineWave.OffsetY + sineWave.A * Math.Sin(sineWave.Omega * evt.X + sineWave.Phi);




if (evt.Z_Out)


{


if (evt.Z < maxZ)


evt.Z += random.Next(0, 3) / 200d;


else


evt.Z_Out = false;


}


else


{


if (evt.Z > minZ)


evt.Z -= random.Next(0, 3) / 200d;


else


evt.Z_Out = true;


}




OnFlyChanging(evt);


}




public void Start()


{


InitData();


timer.Start();


}




public void Stop()


{


timer.Stop();


}




public void Score()


{


try


{


lock (objLock)


{


Singleton<Scorer>.Instance.Score += 1;


Singleton<Scorer>.Instance.Level = (int)Singleton<Scorer>.Instance.Score / 10 + 1;


}


}


finally {}


}




public event EventHandler<FlyEventArgs> FlyChanging;


protected virtual void OnFlyChanging(FlyEventArgs e)


{


EventHandler<FlyEventArgs> handler = FlyChanging;


if (handler != null)


handler(this, e);


}


}


}



2、苍蝇控件的View

IFlyView.cs


using System;


using System.Net;


using System.Windows;


using System.Windows.Controls;


using System.Windows.Documents;


using System.Windows.Ink;


using System.Windows.Input;


using System.Windows.Media;


using System.Windows.Media.Animation;


using System.Windows.Shapes;




namespace YYFly.View


{


public interface IFlyView


{


/// <summary>


/// 更新苍蝇的位置


/// </summary>


/// <param name="x">X 轴坐标</param>


/// <param name="y">Y 轴坐标</param>


/// <param name="z">Z 轴方向上的缩放比例</param>


void Update(double x, double y, double z);




/// <summary>


/// 苍蝇开始飞的事件处理器


/// </summary>


event EventHandler Start;


/// <summary>


/// 苍蝇停止飞的事件处理器


/// </summary>


event EventHandler Stop;


/// <summary>


/// 打死苍蝇后的计分事件


/// </summary>


event EventHandler Score;


}


}



Fly.xaml.cs


using System;


using System.Windows;


using System.Windows.Controls;


using System.Windows.Documents;


using System.Windows.Ink;


using System.Windows.Input;


using System.Windows.Media;


using System.Windows.Media.Animation;


using System.Windows.Shapes;




namespace YYFly.View


{


public partial class Fly : UserControl, IFlyView


{


public Fly()


{


InitializeComponent();




this.Loaded += new RoutedEventHandler(Fly_Loaded);


}




void Fly_Loaded(object sender, RoutedEventArgs e)


{




}




/// <summary>


/// 更新苍蝇的位置


/// </summary>


/// <param name="x">X 轴坐标</param>


/// <param name="y">Y 轴坐标</param>


/// <param name="z">Z 轴方向上的缩放比例</param>


public void Update(double x, double y, double z)


{


fly.SetValue(Canvas.LeftProperty, x);


fly.SetValue(Canvas.TopProperty, y);


st.ScaleX = st.ScaleY = z;


}




/// <summary>


/// 打到苍蝇后


/// </summary>


/// <param name="sender"></param>


/// <param name="e"></param>


private void fly_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)


{


if (aniWing.GetCurrentState() != ClockState.Stopped)


{


aniFlyDisappear.Begin();




OnScore();


}


}




/// <summary>


/// 苍蝇消失的动画结束后


/// </summary>


/// <param name="sender"></param>


/// <param name="e"></param>


private void aniFlyDisappear_Completed(object sender, EventArgs e)


{


OnStop();


}




/// <summary>


/// 初始化苍蝇的位置


/// </summary>


public void InitPosition()


{


fly.SetValue(Canvas.LeftProperty, -300d);


}




public event EventHandler Start;


public void OnStart()


{


InitPosition();




aniFlyDisappear.Stop();




if (Start != null)


Start(this, EventArgs.Empty);


}




public event EventHandler Stop;


public void OnStop()


{


InitPosition();




if (Stop != null)


Stop(this, EventArgs.Empty);


}




public event EventHandler Score;


public void OnScore()


{


if (Score != null)


Score(this, EventArgs.Empty);


}


}


}

3、苍蝇控件的Presenter

FlyPresenter.cs


using System;


using System.Net;


using System.Windows;


using System.Windows.Controls;


using System.Windows.Documents;


using System.Windows.Ink;


using System.Windows.Input;


using System.Windows.Media;


using System.Windows.Media.Animation;


using System.Windows.Shapes;




using YYFly.Model;


using YYFly.View;




namespace YYFly.Presenter


{


/// <summary>


/// Model - View - Presenter 模式中的 Presenter


/// </summary>


public class FlyPresenter


{


public FlyPresenter(IFlyView flyView, IFlyModel flyModel)


{


FlyView = flyView;


FlyModel = flyModel;




FlyView.Start += new EventHandler(FlyView_Start);


FlyView.Stop += new EventHandler(FlyView_Stop);


flyView.Score += new EventHandler(flyView_Score);




FlyModel.FlyChanging += new EventHandler<FlyEventArgs>(FlyModel_FlyChanging);


}




void FlyView_Start(object sender, EventArgs e)


{


FlyModel.Start();


}




void FlyView_Stop(object sender, EventArgs e)


{


FlyModel.Stop();


}




void flyView_Score(object sender, EventArgs e)


{


FlyModel.Score();


}




void FlyModel_FlyChanging(object sender, FlyEventArgs e)


{


FlyView.Update(e.X, e.Y, e.Z);


}




public IFlyView FlyView { get; set; }


public IFlyModel FlyModel { get; set; }


}


}
