SKGroupLayer Class Reference
SKGroupLayer
public class SKGroupLayer : SKTiledLayerObjectOverview
Subclass of SKTiledLayerObject, the group layer is a container for managing groups of layers.
Usage
Query child layers:
for child in group.layers {
child.opacity = 0.5
}
Add layers to the group with:
groupLayer.addLayer(playerLayer)
Remove with:
groupLayer.removeLayer(playerLayer)
-
Returns the last index for all layers.
Declaration
Swift
public var lastIndex: Int { get } -
Returns the last (highest) z-position in the map.
Declaration
Swift
public var lastZPosition: CGFloat { get } -
▶︎layersReturns a flattened array of child layers.
Declaration
Swift
override public var layers: [SKTiledLayerObject] { get }
-
Returns all layers, sorted by index (first is lowest, last is highest).
Declaration
Swift
public func allLayers() -> [SKTiledLayerObject]Return Value
[SKTiledLayerObject]array of layers. -
Returns an array of layer names.
Declaration
Swift
public func layerNames() -> [String]Return Value
[String]layer names. -
Add a layer to the layers set. Automatically sets zPosition based on the tilemap zDeltaForLayers attributes.
Declaration
Swift
@discardableResult public func addLayer(_ layer: SKTiledLayerObject, clamped: Bool = true) -> (success: Bool, layer: SKTiledLayerObject)Parameters
layerSKTiledLayerObjectlayer object.clampedBoolclamp position to nearest pixel.Return Value
(success: Bool, layer: SKTiledLayerObject)add was successful, layer added. -
Remove a layer from the current layers set.
Declaration
Swift
public func removeLayer(_ layer: SKTiledLayerObject) -> SKTiledLayerObject?Parameters
layerSKTiledLayerObjectlayer object.Return Value
SKTiledLayerObject?removed layer.
-
Update the group layer before each frame is rendered.
Declaration
Swift
override public func update(_ currentTime: TimeInterval)Parameters
currentTimeTimeIntervalupdate interval.
