游戏人生Silverlight(3) - 打苍蝇[Silverlight 2.0(c#)]
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; } }}
OK
