The Offset animation is used to move the control from one place to another. Offset animation is applied to all the XAML elements in its parent control/panel. Offset animation doesn't affect the functionality of the control.

Properties

EasingType

You can change the way how the animation interpolates between keyframes by defining the EasingType.

EasingType	Explanation	Graphical Explanation
Default	Creates an animation that accelerates with the default EasingType which is specified in AnimationExtensions.DefaultEasingType which is by default Cubic
Linear	Creates an animation that accelerates or decelerates linear
Back	Retracts the motion of an animation slightly before it begins to animate in the path indicated
Bounce	Creates a bouncing effect
Circle	Creates an animation that accelerates or decelerates using a circular function
Cubic	Creates an animation that accelerates or decelerates using the formula f(t) = t3
Elastic	Creates an animation that resembles a spring oscillating back and forth until it comes to rest
Quadratic	Creates an animation that accelerates or decelerates using the formula f(t) = t2
Quartic	Creates an animation that accelerates or decelerates using the formula f(t) = t4
Quintic	Create an animation that accelerates or decelerates using the formula f(t) = t5
Sine	Creates an animation that accelerates or decelerates using a sine formula

Methods

Examples

• You can just call Offset() set the control in the original position

  Sample Code

  await MyUIElement.Offset().Start();
  

  Await MyUIElement.Offset().Start()
  

• Use await to create a continuous movement

  Sample Code

  public async void OffsetAsync()
  {
      await MyUIElement.Offset(offsetX: 100, duration:1000).StartAsync();
      await MyUIElement.Offset(offsetX: 100, offsetY: 100, duration: 1000).StartAsync();
      await MyUIElement.Offset(offsetX: 0, offsetY:100, duration: 1000).StartAsync();
      await MyUIElement.Offset(duration: 1000).StartAsync();
  }
  

  Public Async Function OffsetAsync() As Task
      Await MyUIElement.Offset(offsetX:=100, duration:=1000).StartAsync()
      Await MyUIElement.Offset(offsetX:=100, offsetY:=100, duration:=1000).StartAsync()
      Await MyUIElement.Offset(offsetX:=0, offsetY:=100, duration:=1000).StartAsync()
      Await MyUIElement.Offset(duration:=1000).StartAsync()
  End Function

• Use this to create chaining animations with other animations. Visit the AnimationSet documentation for more information.

  Sample Code

  var anim = MyUIElement.Light(5).Offset(offsetX: 100, offsetY: 100).Saturation(0.5).Scale(scaleX: 2, scaleY: 2);
  anim.SetDurationForAll(2500);
  anim.SetDelay(250);
  anim.Completed += animation_completed;
  anim.Start();
  

  Dim anim = MyUIElement.Light(5).Offset(offsetX:=100, offsetY:=100).Saturation(0.5).Scale(scaleX:=2, scaleY:=2)
  anim.SetDurationForAll(2500)
  anim.SetDelay(250)
  AddHandler anim.Completed, AddressOf animation_completed
  anim.Start()
