WinForm Animation Library [.Net3.5+]

A simple library for animating controls/values in .Net WinForm (.Net 3.5 and later). Key frame (Path) based and fully customizable.

Please note that even though this library designed for WinForm but its usage is not limited to WinForm and can be used in other environments. Only reference of the library is to 'System.Drawing' name space.

How to get

This library is available as a NuGet package at nuget.org.

Documentation

Float2D: A class containing two float values as Vertical and Horizontal coordinates representing a point in a 2D plane.
Float3D: A class containing three float values as Vertical, Horizontal and Depth coordinates representing a point in a 3D plane.
Path: A class containing a float starting and a float ending point for a single dimensional animation as well as duration and the function to control the animation.
Path2D: A class containing a Float2D starting and a Float2D ending point for a two dimensional animation as well as duration and the function to control the animation.
Path3D: A class containing a Float3D starting and a Float3D ending point for a three dimensional animation as well as duration and the function to control the animation.
Animator: A class for animating an array of Path objects. This class is one of the main classes and starting points of a basic animation.
Animator2D: A class for animating an array of Path2D objects. This class is one of the main classes and starting points of a basic animation.
Animator2D: A class for animating an array of Path3D objects. This class is one of the main classes and starting points of a basic animation.
SafeInvoker: A class holding a reference to a function to invoke in the correct thread, detected by a Control object passed to it. Useful for easier UI manipulations.
SafeInvoker<T>: Same as SafeInvoker class but with a generic argument for the function to invoke.

For full documentation of the classes and their members, please take a look at our doxygen page at falahati.github.io.

Basic examples

ONE DIMENSIONAL ANIMATION OF A PROPERTY

Following code animates a property named Value of a ProgressBar named pb_progress in 5 seconds from zero to one hundred:

new Animator(new Path(0, 100, 5000))
    .Play(pb_progress, Animator.KnownProperties.Value);

TWO DIMENSIONAL ANIMATION OF A PROPERTY

Following code animates a Form in two paths. First one moves the Form from (0, -100) to (100, 200) and second path waits for 3 seconds and then moved the Form to its initial location in 2 seconds. (this is a Form)

new Animator2D(
        new Path2D(0, 100, -100, 200, 5000).ContinueTo(this.Location.ToFloat2D(), 2000, 3000))
    .Play(this, Animator2D.KnownProperties.Location);

THREE DIMENSIONAL ANIMATION OF A PROPERTY

Following code animates a property named CustomColor of a Control named c_customLabel in 2 seconds and after a delay of 1 second using the AnimationFunctions.CubicEaseIn function and with maximum of 10 frames per second.

new Animator3D(
        new Path3D(Color.Blue.ToFloat3D(), Color.Red.ToFloat3D(), 2000, 1000, AnimationFunctions.CubicEaseIn), 
        FPSLimiterKnownValues.LimitTen)
    .Play(c_customLabel, "CustomColor");

KEYFRAMES

There are extension methods for Path, Path2D, Path3D and their arrays to let you continue the path easily and define the key frames as fast as possible. For example, following code moves a Control named c_control in a rectangular path infinitely:

new Animator2D(
    new Path2D(new Float2D(100, 100), new Float2D(200, 100), 1000)
        .ContinueTo(new Float2D(200, 200), 1000)
        .ContinueTo(new Float2D(100, 200), 1000)
        .ContinueTo(new Float2D(100, 100), 1000))
{
    Repeat = true
}.Play(c_control, Animator2D.KnownProperties.Location);

CALLBACKS

It is possible to define a custom callback as frame handler as well as defining a call back to handle the end of the animation. Following example will call a method named CustomSetMethod for setting new values and handle the frames, and starts the animation in reverse path after its end for one more time:

var animator = new Animator(new Path(100, 200, 1000).ContinueTo(400, 500));
animator.Play(new SafeInvoker<float>(CustomSetMethod), new SafeInvoker(() =>
{
    animator.Paths = animator.Paths.Select(path => path.Reverse()).Reverse().ToArray();
    animator.Play(new SafeInvoker<float>(CustomSetMethod));
}));
