Add sub scene to current state as sub state?

[chengenzhao]

Hi:

We are using game sub scene for demonstrating battle scene now
The problem is if we push new sub scene
then the previous game scene will freeze/stop updating
and we hope to add a new game scene but without interrupting previous game scene
we need both game scenes to update during the game

and we read the source code
seems like the state machine allows current state to have more sub states
so is it possible to provide a method like

pushSubSceneToCurrentState(scene);//  (and a counter method popSubSceneFromCurrentState())

to add new sub scene to the current state as sub state rather than replace it
since the previous state will stop updating when new sub scene replace the current state as new state

It seems like is an easy methods to implements?

Thanks

Solved
All I need to do is create a sub class extends game sub scene and then
override this method

  @Override
  public boolean isAllowConcurrency() {
    return true;
  }

Then it will allow concurrent running

import com.almasb.fxgl.app.scene.GameSubScene;

public class MyGameSubScene extends GameSubScene {
  public MyGameSubScene(int width, int height) {
    super(width, height);

  }

  public MyGameSubScene(int width, int height, boolean is3D) {
    super(width, height, is3D);
  }

  @Override
  public boolean isAllowConcurrency() {
    return true;
  }
}
