Reuse same sprite node within multiple scenes in sprite kit using Swift -

i create sprite node in gamescene following. reuse createnodea1 or nodea1 in other skscene. how can that?

import spritekit  class gamescene: skscene {  var nodea1: sknode!  required init?(coder adecoder: nscoder) {     super.init(coder: adecoder) }  override init(size: cgsize) {     super.init(size: size)      // add sprite node scene             nodea1 = createnodea1()     addchild(nodea1)      } }  // create dot 1 func createnodea1() -> sknode {     let spritenode = sknode()     spritenode.position = cgpointmake(cgrectgetmidx(self.frame)/1.5, cgrectgetmidy(self.frame)/2.0)      let sprite = skspritenode(imagenamed: "dot_1")     sprite.zposition = 3.0     sprite.name = "a1_broj"     spritenode.addchild(sprite)      return spritenode }  } 

there few ways this.

you subclass other scenes subclass of scene loadnode function gives scenes access function.

i asked question last year

swift multiple level scenes

another way might bit easier if not comfortable scene subclassing create subclass of node itself.

so create class

enum enemytype {    case normal    case special }    class nodea1: skspritenode {     init(imagenamed: string, enemytype: enemytype) {       let texture = sktexture(imagenamed: imagenamed)        if enemytype == .normal {            super.init(texture: texture, color: skcolor.clearcolor(), size: texture.size())       else {          // other init       }       self.zposition = 1      self.name = ""      // add physics body, other properties or methods node      } } 

than in skscenes can add node in init method so

  nodea1 = nodea1(imagenamed: "imagename", enemytype: .normal)   nodea1.position = ....   addchild(nodea1) 

this way ever scene add node use subclass , therefore include properties, set etc node. benefit subclassing loop through nodes using

self.enumeratechildnodeswithname... 

and call custom methods on nodes.

if want subclass scenes create basescene

 class basescene: skscene {       // set shared stuff in didmovetoview      // have node function here       // touches began      // physics word , contact collision       // other stuff needs shared between level scenes     } 

than subsequent level scenes this

  class level1scene: basescene {       override func didmovetoview(view: skview) {            super.didmovetoview(view) // lines imports stuff in basescene didmovetoview          // level 1 specific setups.        // can call function or property basescene, e.g loadnode function.   } 

you load level scenes usual, e.g transition level 1 scene , automatically use/have access superclass methods , sprites (basescene). never call basescene directly, gets called automatically.

this applies other methods in basescene too, have update method in basescene.

 override func update(currenttime: cftimeinterval) {.... } 

this work across level scenes subclasses of basescene.

but happens if need add specific stuff update method relevant in 1 level scene , not level scenes? same process, create new update func in levelscene , call super.

 override func update(currenttime: cftimeinterval) {      super.update(currenttime) // calls basescene update method      /// specific stuff level   } 

super means super class of currentscene, basescene if scene subclass of it.

is helping?
