Swift is awesome - but do you ever reminisce about the old days of ActionScript 3.0? The old days of MovieClips, DisplayObjects, Sprites, SimpleButtons, EventDispatchers - oh and who can forget gotoAndPlay? Well, now you can enjoy iOS native development using the power of Swift syntax but with the AS3 SDK! Whaa? How is this possible? Is this heresy?
ActionSwift3
Underneath the hood ActionSwift3 is based on the SpriteKit Framework but ActionSwift 3 SDK is based on familiar AS3 SDK classes:
Easing classes are also included for convenience from here.
API documentation can be found at cocoadocs
ActionSwift is available through CocoaPods. To install it, simply add the following line to your Podfile:
ruby
pod "ActionSwift3"
Don't forget to import the Pod where you would like to use it:
Swift
import ActionSwift3
Alternatively, if you would like access to the example project as well, clone the github project here.
ActionSwift
ActionSwift is a sample project that you can use to play with ActionSwift3. Start with taking a look at GameViewController.swift. GameViewController does the following:
How to use ActionSwift3
Here is some sample code to get your head around how to use ActionSwift3.
Stage
To begin with, you need to set up the Stage in a ViewController that contains a SKView(this is done for you automatically if you set up a Game-SpriteKit project)
Swift
let stage = Stage(self.view as! SKView)
Sprite
You can now call familiar methods on the stage. For example, you could instantiate a sprite, and draw a rectangle on its graphics property, and then add this sprite to the stage:
Swift
let sprite = Sprite()
sprite.graphics.beginFill(UIColor.redColor())
sprite.graphics.drawRect(10,10,100,44)
sprite.name = "shapes"
stage.addChild(sprite)
MovieClip
To create a movieclip, you will need images within a folder with the extension 'atlas' in your project (eg.'images.atlas'). This will automatically generate a Texture Atlas. Set up an array of these image file names, and pass them in when you instantiate a MovieClip. These will now be the 'frames' of your movieclip, which you will be able to call familiar methods - gotoAndPlay(), gotoAndStop(), stop() and play(). Use Stage.size to get the dimensions of the device. Oh and x=0, y=0 is the top left of the stage. Hooray!
Swift
let walkingTextures = ["walking1","walking2","walking3"]
let movieClip = MovieClip(textureNames: walkingTextures)
movieClip.x = 0
movieClip.y = Stage.size.height - movieClip.height
stage.addChild(movieClip)
SimpleButton
You can create a SimpleButton object, with an up and down state(not much point of over states on touch screens!) You can use sprites(with shapes on the graphics object) or movieclips(with textures) as the states.
Swift
let play = SimpleButton(upState: playUpState, downState: playDownState)
stage.addChild(sprite)
TextField
Use familiar syntax to create a textfield. Build the basics of the textfield using the TextField class, and then apply text formatting to the defaultTextFormat property, using the TextFormat class.
```Swift let text = TextField() text.width = 200 text.text = "Salutations to you, world"
let textFormat = TextFormat(font: "ArialMT", size: 20, leading: 20, color: UIColor.blackColor(), align:.Center) text.defaultTextFormat = textFormat
stage.addChild(text) ```
Sound
Use sound to play sounds included in your project - a big difference though - now wav files are supported as well as mp3. Hooray! Loop the audio, or play it from a point in the file. As per the strange AS3 API, use SoundChannel to stop the sound.
Swift
sound = Sound(name: "ButtonTap.wav")
sound.play()
EventDispatcher
Just as you would expect, Sprites, SimpleButtons and MovieClips will dispatch events. As Swift is not able to check equality between two functions, an additional class called 'EventHandler' stores the EventHandler, along with a string representing the EventHandler, that can be checked for equality. For example, here's how to set up an enterFrame event handler:
Swift
movieClip.addEventListener(EventType.EnterFrame.rawValue, EventHandler(enterFrame, "enterFrame"))
func enterFrame(event:Event) -> Void {
trace("This is called every frame")
}
trace
Oh yeah - and trace is back!
Swift
trace("This is the most amazing thing I've ever seen, trace is back! How did they do this?")

With GEDCOMConverter, parsing a GEDCOM file to native Swift objects is too easy!
Just create a GEDCOM object, passing in the name of your GEDCOM file:
let gedcom = try GEDCOM(fileName:"sample")
The GEDCOM object will automatically generate a head, and individuals, families and sour arrays of data.

Better Easing for SpriteKit in Swift This easing library began life as a port of buddingmonkey's Objective C SpriteKit Easing library to Swift. This library extends upon the basic easing equations available in the SpriteKit framework by Apple.
