MoreSpriteKit

This package offers additional node types and effects which you can use in combination with SpriteKit. In addition it provides extensions to make complicated tasks a bit easier and improve the readability of your code.

All sources are written in Swift.

Example usage

For examples using MoreSpriteKit, please refer to the demo project MoreSpriteKitDemo

MSKAnimatedLabel

SKNode that draws specified text over multiple lines, separated per newLine character. The text typing can also be animated, meaning each character will be added after a specified interval, creating a typewriter effect.

Use public initializer:

public init(text: String,
            horizontalAlignment: SKLabelHorizontalAlignmentMode = .center,
            durationPerCharacter: Double = 0.05,
            fontSize: CGFloat = 12,
            marginVertical: CGFloat = 15.0,
            fontColor: SKColor = .white,
            fontName: String = "Chalkduster",
            skipSpaces: Bool = true
            labelWidth: CGFloat = 0.0
            finishTypingOnTouch: Bool = false)

Where the text can be separated by new line characters to indicate start of new line. Specify a specific labelWidth to wrap all text to a specific width. MSKAnimatedLabel will create new lines where necessary. When the specified labelWidth is to small for a certain CharacterSequence, a fatal error is thrown.

When durationPerCharacter <= 0.0, all lines will be drawn immediately without any animation. When finishTypingOnTouch equals true, all remaining lines will be drawn instantly without any animation when a user taps the label.

MSKEmitterLabel

SKNode that draws specified text using an emitter that follows the characters outlines, over a given duration.

Use public initializer:

public init(text: String,
            font: UIFont,
            emitterName: String,
            marginHorizontal: CGFloat = 10.0,
            animationDuration: Double = 2.0,
            addEmitterInterval: Double = 0.1)

SKAction+Spiral

Extension on SKAction allowing to create a spiraling movement. Usage:

SKAction.spiral(startRadius: radius,
                endRadius: radius-50,
                totalAngle: CGFloat(.pi * 2.0),
                centerPoint: .zero,
                duration: 1.5)

SKAction+Shake

Extension on SKAction allowing to create a shake effect. NB preview as GIF is not very useful, for proper demonstration please see the example application.

Usage:

SKAction.shake(shakeDuration: 0.2,
               intensity: arc4random_uniform(40)+10,
               duration: 3)

SKShapeNode+Arrow

Extension on SKShapeNode allowing to create a node with an arrow shape. Usage:

let arrow = SKShapeNode(arrowWithFillColor: randomColor,
                        strokeColor: randomColor,
                        lineWidth: 4,
                        length: 100,
                        tailWidth: 20,
                        headWidth: 50,
                        headLength: 30)

SKTexture+RadialGradient

Extension on SKTexture allowing to create a texture with a radial gradiant. Could be used for example for range nodes, indicating a creatures attack range. Usage:

let radialGradientSize = CGSize(width: 150, height: 150)
let radialGradientColors = [UIColor.red, UIColor.blue, UIColor.green, UIColor.blue, UIColor.orange]
let radialGradientLocations: [CGFloat] = [0, 0.25, 0.45, 0.65, 1.0]

let radialTexture = SKTexture(radialGradientWithColors: radialGradientColors,
                              locations: radialGradientLocations,
                              size: radialGradientSize)

let radialNode = SKSpriteNode(texture: radialTexture)

SKTexture+LinearGradient

Extension on SKTexture allowing to create a texture with a linear gradiant. Could be used for example for a healthbar. Usage:

let linearGradientSize = CGSize(width: 150, height: 30)
let linearGradientColors: [UIColor] = [.red, .yellow, .green, .yellow, .red]
let linearGradientLocations: [CGFloat] = [0, 0.35, 0.5, 0.65, 1.0]

let linearGradientTexture = SKTexture(linearGradientWithColors: linearGradientColors,
                                      locations: linearGradientLocations,
                                      size: linearGradientSize)

let gradientNode = SKSpriteNode(texture: linearGradientTexture)

SKAction+TimingMode and Array+SKAction

• Public extensions on SKAction to add a timingMode or for example a repeatForever inline.
• Public extensions on Array to convert it inline to a SKAction.group or SKAction.sequence.

Usage:

let actions: [SKAction] = [.run { self.addEmitterLabel() }, .wait(forDuration: 10)]
run(actions.sequence().forever())

Requirements

• iOS 10.3+
• Xcode 10.1+
• Swift 5+

Installation

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding MoreSpriteKit as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/sanderfrenken/MoreSpriteKit", .upToNextMajor(from: "1.0.0"))
]

Manually

If you prefer not to use any of the aforementioned dependency managers you can integrate the desired sources in your project manually, by adding the corresponding Swift files to your project.

SwiftLint

We use Swiftlint from Realm to lint our code. More info can be found on SwiftLint. Details about the specific settings for this project can be found in the .swiftlint.yml file.
