Codruts Animation Library

Codrut-Animation-Lib

Codruts Animation Library is a simple component-based animation library for Delphi VCL. It's similar to the official FMX counterpart.

It can also support sub-classes!

If a property like top works, you can also use margin.top to change the sub-property of the class margin! You can also use as many sub-classes as you wish. Like Button1.Margin.Interior.Size.Left!

Component

Image	Description
	The animation control on the form
	To make the animation work, first select a component to animate, the animation, the start and end value and the property to change

Start / stop animation

You can change the Running property, or use the Start or Stop procedures.

You may also pause the animation using the Paused property.

Properties

Property	Type	Description
Component	TComponent	The component of which the property will be changed (optional)
CurrentValue	{AnimationType}	The current animation value (Read-only)
Delay	Single	The time waited before the animation actually starts in seconds, also can be in-between loops
DelayLoop	Toggle to wait the Delay amout inbetween loops
Duration	Single	The animation duration
EndValue	{AnimationType}	The end value
Inverse	Boolean	Execute from End to Start
Kind	TAnimationKind	The animation function used
Loop	Boolean	Restart the animation on end
LoopInverse	Boolean	Toggle the inverse property on loop
Percent	Single	The percentage of the animation being finalised (Read-only)
PropertyName	String	The property to change. Can also access properties of sub-classes with the . separator. (optional)
StartFromCurrent	Boolean	Defines if the start value is determined by the current Component Value (Requires component and PropertyName)
StartValue	{AnimationType}	The value from which the animation starts. Can be overriden by StartFromCurrent
Steps	Integer	Set a custom steps value for the animation, instead of auto-calculating them. The less steps the greater the drawing performance

Animation types

• Linear
• Exponential
• Pulse
• Random
• ReverseExpo
• Sinus
• SinusAr
• Wobblyc
• Spring

Note: Pulse and Wobbly do not reach their end value, as they return back to their start value.

Use without component

1. Assign the OnStep notify event from the Object Inspector.
2. Get the CurrentValue property from the Sender
3. Use the value as needed Example:

  procedure TForm1.NewAnimation1Step(Sender: TObject; Step, TotalSteps: Integer);
  var
    Value: integer;
  begin
    Value := TIntAnim(Sender).CurrentValue;
  
    // now use the value
  end;
