Silverlight 动画效果1 -- 旋转
效果如下:
代码如下:
Storyboard sb,sb2;
PlaneProjection pp;
private void button1_Click(object sender,RoutedEventArgs e)
{
if (this.Projection == null)
{
this.Projection= pp = new PlaneProjection
{
RotationY=0 //--Y轴角度为0
};
}
if (sb == null)
{
sb = new Storyboard();
DoubleAnimation da = new DoubleAnimation();
Storyboard.SetTarget(da,this.Projection);
Storyboard.SetTargetProperty(da,new PropertyPath("RotationY"));//--旋转Y轴
sb.Children.Add(da);
da.From = 0;//--从0度开始
da.To = 90; //--旋转90度
da.Duration = TimeSpan.FromSeconds(0.5); //时间0.5s
sb.Completed += new EventHandler(sb_Completed);//转完一半开始别一半
}
sb.Begin();//开始
}
void sb_Completed(object sender,EventArgs e)
{
if (sb2 == null)
{
sb2 = new Storyboard();
DoubleAnimation da = new DoubleAnimation();
Storyboard.SetTarget(da,new PropertyPath("RotationY"));
sb2.Children.Add(da);
da.From = 270;//从270度开始
da.To = 360;//到360度
da.Duration = TimeSpan.FromSeconds(0.5);
sb2.Completed += new EventHandler(sb2_Completed);
}
this.Title = this.Title == "测试一" ? "测试二" : "测试一";
sb2.Begin();
}
void sb2_Completed(object sender,EventArgs e)
{
}
