SKTiled




















**SKTiled** is a framework for integrating [Tiled][tiled-url] assets with [Apple's SpriteKit][spritekit-url], built from the ground up with Swift. This project began life as an exercise to learn Apple's new programming language for a game project, but I've decided to release it as open source with the hopes that others will find it useful. **SKTiled** is up-to-date and supports **Tiled's** major features, including all map & object types.

## Requirements



- iOS 12

- tvOS 12

- macOS 11

- Xcode 11/Swift 5



## Installation



### Carthage



For Carthage installation, create a Cartfile in the root of your project:



    github "mfessenden/SKTiled" ~> 1.2



To use the new **[binary framework][binary-frameworks-url]** format, pass the **`--use-xcframeworks`** parameter to the build command:



	carthage update --use-xcframeworks



For more information, see the **[Carthage Installation][docs-carthage-url]** documentation.



### CocoaPods



For CocoaPods, install via a reference in your podfile:



    pod 'SKTiled', '~> 1.2'



## Usage



Loading a tilemap is very straightforward:



```swift

if let tilemap = SKTilemap.load(tmxFile: "sample-map") {

    scene.addChild(tilemap)

}

```

Once loaded, the rendered [`SKTilemap`][sktilemap-url] node reflects the various properties defined in the originating scene:



- `SKTilemap.size`: size of the map in tiles.

- `SKTilemap.tileSize`: size of individual tiles.

- `SKTilemap.orientation`: map orientation (ie orthogonal, isometric, etc).



The [`SKTilemap`][sktilemap-url] node also gives users access to child layers, tilesets, objects or individual tiles.



### Working with Layers



Layers represent containers that hold various types of data:



- tile layers hold an array of tile sprites and associated tileset data

- object groups contain vector shape objects

- image layers display a single image

- group layers encapsulate other layers



All **SKTiled** layer types are subclasses of the base [`SKTiledLayerObject`][sktiledlayerobject-url] object and provide access to coordinate transformation and positioning information. Additionally, every layer type can have individual offset transforms and rendering flags.  



Layers can be accessed by type, name or index:



```swift

// query layers by type

let tileLayers = tilemap.tileLayers

let objectGroups = tilemap.objectGroups

let imageLayers = tilemap.imageLayers

let groupLayers = tilemap.groupLayers



// query named layers

let groundLayers = tilemap.getLayers(named: "Ground") as! [SKTileLayer]

let objectGroups = tilemap.getLayers(named: "Objects") as! [SKObjectGroup]

let hudLayers = tilemap.getLayers(named: "HUD") as! [SKImageLayer]



// query layer at a specific index

if let firstLayer = tilemap.getLayer(atIndex: 1) as! SKTileLayer {

    firstLayer.visible = true

}

```



### Working with Tiles



There are a number of ways to access and manipulate tile objects. Tiles can be queried from the [`SKTilemap`][sktilemap-url] node, or the parent [`SKTileLayer`][sktilelayer-url] layer:



```swift

// access a tile via CGPoint

let tileCoord = CGPoint(x: 7, y: 12)

if let tile = groundLayer.tileAt(coord: tileCoord) {

    tile.tileData.tileOffset.x += 8

}



// access a tile with integer coordinates

if let tile = groundLayer.tileAt(7, 12) {

    tile.tileData.tileOffset.x += 8

}



// query tiles at a specific coordinate (all layers)

let tiles = tilemap.tilesAt(2, 4)

```



Tiles assigned custom properties in **Tiled** can be accessed in **SKTiled**:



```swift

// query tiles of a certain type

if let fireTiles = tilemap.getTiles(ofType: "fire") {

    // do something fiery here...

}

```



You can also return tiles with a specific ID value:



```swift

if let waterTiles = waterLayer.getTiles(globalID: 17) {

    // do something watery here...

}

```



### Working with Objects



`SKTileObject` objects can be queried from both the [`SKTilemap`][sktilemap-url] and [`SKObjectGroup`][skobjectgroup-url] nodes:



```swift

let allObjects = tilemap.getObjects()

let allTreeObjects = tilemap.getObjects(named: "Tree")

let allCollisionObjects = tilemap.getObjects(ofType: "Collision")



// get objects from the objects group layer

let entrances = objectsLayer.getObjects(ofType: "Entrance")

```



### Acessing Tile Data



The [`SKTilemap`][sktilemap-url] node stores an array of individual tilesets parsed from the original **Tiled** document. Individual tile data is accessible from either the [`SKTileset`][sktileset-url] object:



```swift

let tileSet = tilemap.getTileset("spritesheet-16x16")

// get data for a specific id

let tileData = tileSet.getTileData(globalID: 177)

```



and the parent [`SKTilemap`][sktilemap-url]:



```swift

let tileData = tilemap.getTileData(globalID: 177)

```



## Adding Nodes



Tile data includes texture data, and [`SKTile`][sktile-url] objects are [`SKSpriteNode`][skspritenode-url] subclasses that can be initialized with tileset data:



```swift

let newTile = SKTile(data: tileData)

scene.addChild(newTile)

```



Coordinate information is available from each layer via the [`SKTiledLayerObject.pointForCoordinate`][sktiledlayerobject-pointforcoordinate-url] method:



```swift

let tilePoint = groundLayer.pointForCoordinate(4, 5)

tile.position = tilePoint

```



New nodes (any [`SKNode`][sknode-url] type) can be added directly to any layer. All [`SKTiledLayerObject`][sktiledlayerobject-url] layer types have expanded convenience methods for adding child nodes with coordinates and z-position.



```swift

let roadRoot = SKNode()

groundLayer.addChild(roadRoot, 4, 5, zpos: 100.0)

```



**SKTiled** also provides methods for getting coordinate data from [`UITouch`][uitouch-url] and [`NSEvent`][nsevent-url] mouse events:



```swift

// get the coordinate at the location of a touch event

let touchLocation: CGPoint = objectsLayer.coordinateAtTouchLocation(touch)

```



## Animated Tiles



Tiles with animation will animate automatically when the tilemap node is added to the [`SKScene.update`][skscene-update-url] method. Animated tiles can be accesssed from the either the [`SKTilemap`][sktilemap-url] node or the parent layer.



```swift

// get all animated tiles, including nested layers

let allAnimated = tilemap.animatedTiles(recursive: true)



// pause/unpause tile animation

for tile in allAnimated {

    tile.isPaused = true

}



// run animation backwards

for tile in allAnimated {

    tile.speed = -1.0

}



// get animated tiles from individual layers

let layerAnimated = groundLayer.animatedTiles()

```



## Custom Properties



Custom properties are supported on all object types. All **SKTiled** objects conform to the [`SKTiledObject`][sktiledobject-url] protocol and allow access to and parsing of custom properties.



Any property added to an object in **Tiled** will be translated and stored in the `SKTiledObject.properties` dictionary.



```swift

let layerDepth = groundLayer.getValue(forProperty: "depth")

groundLayer.setValue(12.5, forProperty: "depth")

```



To query tiles of a given type:



```swift

let waterTiles = groundLayer.getTiles(ofType: "water")

let allWaterTiles = tilemap.getTiles(ofType: "water")

```



For specific property/value types:



```swift

let groundWalkable = groundLayer.getTilesWithProperty("walkable", true)

let allWalkable = tilemap.getTilesWithProperty("walkable", true")

```
