Swift And Spritekit SceneDidLoad Being Called More Than One

- 1 answer

I'm working with a simple game , I have MenuScene : the user can choose the type of the game and GamePlayScene .

First time user choose game type every thing is good , but the second time all methods called twice , and the third time methods called three time etc .

I try to use didMoveToView but still have the same problem.

should I delete the scene after finish the game ? if yes how?.

this is how I transition between scenes .

extension SKScene {
    func presentSceneWith(NameOfScene scene : String){
        if let scene = SKScene(fileNamed: scene){
            scene.scaleMode = .aspectFill

I use it for present to GamePlayScene and back to MenuScene.



First : I'm using Firebase Database .

So the problem is : I was using If Statement inside the observe .

like :

private func searchForOpponents(){
   let ref = Database.database().reference()
   ref.child("activePlayers").child("waiting").observe( DataEventType.value) { (snapshot) in
   // the problem when I put if statement like this
   if snapshot == something {

ref.observe called more than one in the second so basically I was present to next scene more than one time .

The solution : in my case I use ref.observeSingelEvent() and change the DataEventType to childChange .
