WPF - 创建浮动动画可点击控件（图像或...）
WPF - Create a floating animated clickable control (image or...)
我想创建一个 浮动动画可点击 控件，就像在我的 WPF 应用程序中有时也会向右或向左移动的氦气球。
The helium balloons likes go up! but also they moves right or left if
we tap on them or by wind.
In advance cases, sometimes they turn to right or left
..............................................
所以我在网上搜索但没有找到任何有用的示例项目或库或样式。
我如何在 WPF 中创建样式和动画以显示图像或
控制漂浮或悬浮在空中。?
你有什么建议来简单地实现这个想法......？
编辑：
- 你对 随机和无限平滑地向右和向左转 有何建议？例如向左 51 度然后向右 163 度......我想把我的气球放在我的 window 和 经常在 window.[=46 的顶部=]
编辑：
我根据这些答案创建了一个动画，但通过操纵它们并在气球图像及其容器上添加多个并行动画而变得更加复杂。 ;)
谢谢大家...
现在我的初步结果是这样的：
在 C# 中 DoubleAnimation 是一个强大的 Class 在 System.Windows.Media.Animation; 命名空间中支持动画 所以这个 class 有一些方法和属性让我告诉你它
DoubleAnimation ANobj = new DoubleAnimation();//make object from DoubleAnimation
ANobj.From=0 //the 0 is point you want to star animation
ANobj.To=270//the end pont of moving
// that values is dependent on your self as you want
ANobj.Duration = new Duration(TimeSpan.FromSeconds(60)); //specify the duration of moving
ANobj.RepeatBehavior = RepeatBehavior.Forever;//RepeatBehavior as you want
还可以使用 RotateTransform class 在 WPF 中旋转 C# 组件
RotateTransform RTobj=new RotateTransform();//make object from RotateTransform
RTobj.CenterX = 277;//X point of your Element(Componet)
RTobj.CenterY = 245;//Y point of your Element(Componet)
RTobj.Angle = 360;//angle between
RTobj.BeginAnimation(RotateTransform.AngleProperty,ANobj);
同样在执行此操作后，将此对象从您的元素中设置为 RenderTransform 属性 喜欢它
yourElementName.RenderTransform=RTobj
如果您想在 MSDN 阅读更多关于 System.Windows.Media.Animation
这是我在高中做的。现在可能已经过时了，但只是为了兴趣。
//the animation thread
System.Threading.Thread thr;
thr = new System.Threading.Thread(annimate);
thr.Start();
动画方法

try

double angleToAnimateTo = 20;
double CurrentAngle = 0;
bool increment = false;
while (IsAnimating)
{
if (increment)
CurrentAngle++;
else
CurrentAngle--;
if (CurrentAngle == angleToAnimateTo )
increment = false;
if (CurrentAngle == (angleToAnimateTo * -1))
increment = true;
this.Dispatcher.Invoke((Action)(() =>

this.imgBallon.RenderTransform = new RotateTransform(CurrentAngle);
}));
System.Threading.Thread.Sleep(100);
}
}

imgBalloon 是 wpf 中的一个简单图像。这是 xaml..

您可以像@Ega 提到的那样使用 DoubleAnimation 和 RotateTransform 来实现。要回答您的 "random and infinite" 向右和向左转弯，您可以按照以下方法进行操作（非常基本但可以完成工作）。
private async void Button_Click(object sender, RoutedEventArgs e)
{
var rnd = new Random();
var direction = -1;
while (true)
{
var percent = rnd.Next(0, 100);
direction *= -1; // Direction changes every iteration
var rotation = (int)((percent / 100d) * 45 * direction); // Max 45 degree rotation
var duration = (int)(750 * (percent / 100d)); // Max 750ms rotation
var da = new DoubleAnimation
{
To = rotation,
Duration = new Duration(TimeSpan.FromMilliseconds(duration)),
AutoReverse = true // makes the balloon come back to its original position
};
var rt = new RotateTransform();
Balloon.RenderTransform = rt; // Your balloon object
rt.BeginAnimation(RotateTransform.AngleProperty, da);
await Task.Delay(duration * 2); // Waiting for animation to finish, not blocking the UI thread
}
}
编辑 for .NET 3.5
private void Button_Click(object sender, RoutedEventArgs e)
{
var thread = new Thread(this.AnimateBalloon);
thread.Start();
}
public void AnimateBalloon()
{
var rnd = new Random();
var direction = -1;
while (true)
{
var percent = rnd.Next(0, 100);
direction *= -1; // Direction changes every iteration
var rotation = (int)((percent / 100d) * 45 * direction); // Max 45 degree rotation
var duration = (int)(750 * (percent / 100d)); // Max 750ms rotation
Balloon.Dispatcher.BeginInvoke(
(Action)(() =>
{
var da = new DoubleAnimation
{
To = rotation,
Duration = new Duration(TimeSpan.FromMilliseconds(duration)),
AutoReverse = true // makes the balloon come back to its original position
};
var rt = new RotateTransform();
Balloon.RenderTransform = rt; // Your balloon object
rt.BeginAnimation(RotateTransform.AngleProperty, da);
}));
Thread.Sleep(duration * 2);
}
}
Farseer Physics Engine for C# 将允许您创建真实世界的模拟。你可以控制重力、惯性、力甚至其他物理东西。
World world = new World(new Vector2(0f, 9.82f));
//We create a body object and make it dynamic (movable)
Body myBody = world.CreateBody();
myBody.BodyType = BodyType.Dynamic;
//We create a circle shape with a radius of 0.5 meters
CircleShape circleShape = new CircleShape(0.5f);
//We fix the body and shape together using a Fixture object
Fixture fixture = myBody.CreateFixture(circleShape);
对于这种情况，您可能需要创建一个重力较小且物体会飞的世界。您可以从对象的任一侧施加力来移动它。
