Tiled Properties

One of the most useful features of SKTiled is the ability to take advantage of Tiled’s custom properties for most object types. Any object that conforms to the TiledAttributedType protocol will inherit methods for parsing Tiled object properties.

SKTiled supports the newer color and file property types (values are stored as strings internally anyway, which the API already supports). The custom color/file types listed above will also be parsed if they are created as string types in Tiled.

Currently all SKTiled property values are stored as strings, though this might change in the future.

Querying Properties

The TiledAttributedType protocol enables you to easily query attributes in your scenes. The methods work exactly the same for all SKTiled classes.

// access tile data properties
tileData.properties

// query an object to see if it has a named property
floorObject.hasKey("slippery")

// access the named property 'slippery'
let slipperyValue = floorObject.stringForKey("slippery")!

// update the named property 'slippery'
floorObject.setValue(forKey: "slippery", "1.2")

// get tile data that have a named property (regardless of value)
let dynamicObjects = tilemap.getTileData(withProperty: "mass")

// get tile data that have a named property (with a specific value)
let heavyDynamicObjects = tilemap.getTileData(withProperty: "mass", "10.0")

// removing a named property returns the value (or nil if it doesn't exist)
if let levelName = tilemap.removeProperty(forKey: "levelName") {
    print("Level name was '\(levelName)'")
}

Object Types

Type Property

Some object types in Tiled have a special type property (tiles, objects). The base TiledObjectType protocol in SKTiled contains a type property, which means that all SKTiled objects inherit it (not just the objects that Tiled supports).

This means that you can set this attribute for tilesets, all layer types, even the map itself. If the object has a type property in Tiled, that will be assigned as a value. If the object has custom string property type, that will be used instead.

Custom Properties

SKTiled recognizes several custom properties that can be used to change attributes of objects in your Tiled scenes. For instance, adding an zPosition float property to a layer or object in Tiled will override the property in SpriteKit.

If you wish to ignore custom properties when your scene is read, you can pass the ignoreProperties argument to the SKTilemap.load method:

let tilemap = SKTilemap.load(tmxFile: "myTiledFile", ignoreProperties: true)
