The old repository can be found here for older versions of haxe.

Actuate is faster than TweenLite and it is free for all your Flash projects.
Power through your everyday needs using no-nonsense, lightweight tweens, then extend when you need more
It's simple to get started!

Installation

haxelib install actuate

Usage


To use you will need to import Actuate
import motion.Actuate;

And then use it simply
Actuate.tween (MySprite, 1, { alpha: 1 } );

Actuate is designed to be simple to use and to take advantage strong code completion support in code editors like FlashDevelop and Flex Builder, which means no more "reserved" keywords or "special" properties
Actuate.tween (MySprite, 1, { alpha: 1 } ).onComplete (trace, "Hello World!");
Instance-based tweens can be a pain. When you don't keep track of each tween instance, you run the risk of creating conflicting tweens, which almost never turns out well. With first-class tween overwrite support, Actuate manages your tweens so you don't have to. Actuate also makes it simple to disable overwriting when you need to sequence multiple animations
Actuate.tween (MySprite, 1, { alpha: 1 } );
Actuate.tween (MySprite, 1, { alpha: 0 }, false).delay (1);

It's also easy to stop, pause or resume your tweens, too
Actuate.stop (MySprite);
Actuate.stop (MySprite, "alpha");
Actuate.pause ();
Actuate.pause (MySprite);
Actuate.pause (MySprite, MyOtherSprite);
Actuate.resume ();
Actuate.resume (MySprite);
Actuate.resume (MySprite, MyOtherSprite);
Actuate.reset ();

There also are additional shortcuts you can use to help you be even more productive. For example, you can use Actuate to create quick tween-based timers for sequencing events
Actuate.timer (1).onComplete (trace, "Hello World!");
Or you can use the "apply" method to stop conflicting tweens and instantly set an object's properties
Actuate.apply (MySprite, { alpha: 1 } );
Advanced Features
For advanced animations, you can also tween function calls instead of properties
Actuate.update (customResize, 1, [100, 100], [300, 300]);
Actuate also includes shortcuts for some special types of animation. Here is how you might apply a 50% tint using a color transform
Actuate.transform (MySprite, 1).color (0xFF0000, 0.5);
You can also control the volume and pan of a sound transform as well
Actuate.transform (MySprite, 1).sound (0.5, 1);
Actuate.transform (MySoundChannel, 1).sound (0.5, 1);

You can also tween filters. You can reference the filter by its class, or by the value of its index in the filter array, whichever is easier
Actuate.effects (MySprite, 1).filter (BlurFilter, { blurX: 10, blurY: 10 } );

You even can create bezier curves, and complete motion paths, like in the Flash IDE. Chain multiple path commands together to create one solid path you can tween your objects across using the MotionPathActuator
var xPath:MotionPath = MotionPath.bezier (200, 20).line (400);
var yPath:MotionPath = MotionPath.bezier (0, 300).line (0);
Actuate.motionPath (MySprite, 1, { x: xPath, y: yPath } );

Tween Modifiers


Each tween Actuate creates can be modified with many different tween modifiers. You can link tween modifiers to add delay, complete handlers, or configure many different options about the way your tween behaves

autoVisible

Actuate.tween (MySprite, 1, { alpha: 1 } ).autoVisible (false);

Changing the visible property results in better performance than only an alpha of zero, so the autoVisible modifier toggles the visible property automatically based upon the alpha value of the target. It is enabled by default, but it can be disabled if you choose

delay

Actuate.tween (MySprite, 1, { alpha: 1 } ).delay (1);

Controls how many seconds should pass before your animation begins

ease

Actuate.tween (MySprite, 1, { alpha: 1 } ).ease (Quad.easeOut);

Defines a custom easing equation for your animation. Actuate includes many popular easing functions in both standard and optimized formats. The default is Expo.easeOut, but you can change the default equation through Actuate.defaultEase

onComplete

Actuate.tween (MySprite, 1, { alpha: 1 } ).onComplete (trace, "Tween finished");
Calls a function when the tween is finished. You can also define parameters to be used when calling the function

onUpdate

Actuate.tween (MySprite, 1, { alpha: 1 } ).onUpdate (trace, "Tween updated");

Calls a function every time the tween updates. You can also define parameters to be used when calling the function

reflect

Actuate.tween (MySprite, 1, { alpha: 1 } ).repeat ().reflect ();

Automatically reverses the animation every other time it is repeated. You must enable repeat in order to see any effect

repeat

Actuate.tween (MySprite, 1, { alpha: 1 } ).repeat (10);

Runs your animation multiple times before it finishes. You can make your tween repeat indefinitely by passing no value, or you can define the number of times it should repeat

reverse

Actuate.tween (MySprite, 1, { alpha: 1 } ).reverse ();

Reverses the direction of your tween

smartRotation

Actuate.tween (MySprite, 1, { rotation: 180 } ).smartRotation ();

Rotation is circular, so it can be strange to animate. What should be positive one moment is negative the next. As a result, treating rotation like a standard tween will result in jerking once the signs change. Smart rotation always applies rotation in the nearest direction, alleviating this issue.

snapping


Actuate.tween (MySprite, 1, { alpha: 1 } ).snapping ();

Rounds all of your tween values
