EleCho.FluentAnimation

Use Fluent APIs to process animations in WPF.

Usage

Add namespace using.

using EleCho.FluentAnimation.Wpf

Call the extension method FluentAnimator, it returns a FluentAnimator instance for processing animations.

element.FluentAnimator();

Call AnimateBy, AnimateTo, AnimateFromBy, AnimateFromTo methods to process an animation, then call Start method to start these animations.

element.FluentAnimator()
    .AnimateTo(ele => ele.Width, 100)
    .AnimateTo(ele => ele.Height, 100)
    .Start();

You can also directly use some wrapped methods for commonly used attributes, such as AnimateWidthTo, AnimateHeightTo.

element.FluentAnimator()
    .AnimateWidthTo(100)
    .AnimateHeightTo(100)
    .Start();

You can use methods such as WithDuration, WithEasingFunction to configure all animations.

element.FluentAnimator()
    .AnimateWidthTo(100)
    .AnimateHeightTo(100)
    .WithDuration(200)      // 200ms
    .WithEasingFunction(
        new CircleEase() { EasingMode = EasingMode.EaseOut })
    .Start();

You can use Delay or Then to control the order of execution of animations.

element.FluentAnimator()
    .AnimateWidthTo(100)
    .Delay(100)             // delay for 100ms
    .AnimateHeightTo(100)
    .WithDuration(200)      // 200ms
    .Start();

element.FluentAnimator()
    .AnimateWidthTo(100, TimeSpan.FromMilliseconds(200))     // to use continue, you must specify the duration
    .Then()                                                  // delay for the duration of the previous animation
    .AnimateHeightTo(100, TimeSpan.FromMilliseconds(200))    // run the current animation
    .Start();

Animation with attached property.

element.FluentAnimator()
    .AnimateTo(Canvas.LeftProperty, (double)200)
    .WithDuration(200)
    .Start();

Animation with nesting properties.

element.FluentAnimator()
    .AnimateTo(ele => ((SolidColorBrush)ele.Background).Color, Colors.Pink)
    .WithDuration(200)
    .Start();
