如何刪除實體形成實體的SKScene

Question

組件可以被刪除？

有很多關於刪除組件的教程，但我找不到任何關於刪除實體的明確信息。有沒有像刪除節點？

node.removeFromParent();

我適應這個從包含樣品的RenderComponent和LayerConfiguration蘋果DemoBots。

陣列是用在這裏迅速解決>>Array extension to remove object by value

var entities = [GKEntity]() 

/// Stores a reference to the root nodes for each world layer in the scene. 
var layerNodes = [LayerConfiguration:SKNode]() 

func addEntity(entity: GKEntity) 
{ 
    self.entities.append(entity) 

    for componentSystem in self.componentSystems 
    { 
     componentSystem.addComponent(foundIn: entity) 
    } 

    // If the entity has a `RenderComponent`, add its node to the scene. 
    if let renderNode = entity.component(ofType: RenderComponent.self)?.node 
    { 
     self.addNode(node: renderNode, toLayer: .actors) 
    } 
} 

func removeEntity(entity:GKEntity) 
{ 
    for componentSystem in self.componentSystems 
    { 
     componentSystem.removeComponent(foundIn: entity) 
    } 

    if let renderNode = entity.component(ofType: RenderComponent.self)?.node 
    { 
     renderNode.removeFromParent() 
    } 

    self.entities.remove(entity) 
} 

func addNode(node: SKNode, toLayer layer: LayerConfiguration) 
{ 
    // 
    let layerNode = self.layerNodes[layer]! 

    layerNode.addChild(node) 
}
