游戏人生Silverlight(2) - 趣味钢琴[Silverlight 2.0(c#)]

作者：webabcd


介绍
使用 Silverlight 2.0(c#) 开发一个趣味钢琴


玩法
打开音箱，从左侧列表选择要挑战的乐谱，右侧会出现对应的乐谱提示动画，等按键提示移动到目标区后敲击键盘上对应的按键


在线DEMO



思路
1、添加多个MediaElement控件，循环使用，以达到同时播放多个音阶的效果
2、提示按键模块分3组动画，分别为提示部分、目标部分和离开部分，进入目标区和离开目标区都要触发对应的事件，以使外部判断用户是否按照提示正确地敲击了按键


关键代码
1、钢琴音阶播放器
ScalePlayer.xaml.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace YYPiano.Controls.Parts

2、按键提示动画
AnimationKey.xaml

<UserControl x:Class="YYPiano.Controls.Parts.AnimationKey"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Canvas>
        <!--3个椭圆，目标区，按键动画进入该区域后敲击则为有效敲击-->
        <Ellipse x:Name="target" Width="80" Height="80" Stroke="#F80" Fill="Transparent" StrokeThickness="1" Canvas.Left="0" Canvas.Top="250" />

                </TransformGroup>
            </Border.RenderTransform>
        </Border>

        <Canvas.Resources>
            <!--主动画（缓冲提示）-->

                </DoubleAnimationUsingKeyFrames>
            </Storyboard>

            <!--进入目标区后的动画-->
            <Storyboard x:Name="insideAni" Completed="insideAni_Completed" Duration="0:0:0.4">
                <DoubleAnimation To="310" Storyboard.TargetName="tt" Storyboard.TargetProperty="Y" />
            </Storyboard>

            <!--离开目标区后的动画-->
            <Storyboard x:Name="outsideAni">
                <DoubleAnimation To="400" Storyboard.TargetName="tt" Storyboard.TargetProperty="Y" />
                <DoubleAnimation To="0" Storyboard.TargetName="container" Storyboard.TargetProperty="Opacity" />
            </Storyboard>
        </Canvas.Resources>
    </Canvas>
