How to save data between scenes?

[tfkfan]

I didn't found any correct(!) option to do that

Hi @tfkfan

We don't have anything official at the moment.

What would you like to see in your game? It might help us design an API that'd serve your purpose.

In the past in our games we've used an external object that is known to all scenes (maybe even a singleton) to hold onto data between scenes.

@jedeen @kamranayub Any other suggestions?

Hi, so I've found a good solution, that's fine, thanks:

  public onDeactivate(scene, nextScene) {
    if(nextScene instanceof GameScene)
      nextScene.data= this.data;
      }
  }

You can use the engine reference to the main game to store your data :

class Henk extends Actor {
    onInitialise(engine) {
       this.game = engine
   }
   updateScore(){
      this.game.score++
   }
}

Then in any other scene in any other actor you can get the score with

class Wim extends Actor {
    onInitialise(engine) {
       this.game = engine
       console.log(this.game.score)
   }
}
