[VX] asynchron script execution ? [RESOLVED]

[Fustel]

As a test (it was even worst in my main project), I included this simple script in a new project.

Spoiler

class TTestClass
  attr_accessor :bool_value

  def initialization
    @bool_value = false
  end
end

$testobject = TTestClass.new

class TScene_Test < Scene_Base
  def start
    super
    Sound.play_decision    
    create_menu_background    
    @win_cmd = Window_Command.new(136,["set to true","set to false"])
  end

  def terminate
    @win_cmd.dispose
    dispose_menu_background    
    super
  end

  def update
    super
    update_menu_background
    @win_cmd.update

    if Input.trigger?(Input::B)
      Sound.play_cancel
      $scene = Scene_Map.new
    end

    if Input.trigger?(Input::C)
      case @win_cmd.index
        when 0
          $testobject.bool_value = true
        when 1
          $testobject.bool_value = false
      end
      $scene = Scene_Map.new
    end
  end
end

I then create an event doing the following :

Spoiler

Script:$scene = TScene_Test.new
condition: Script: $testobject.bool_value
  Play SE 'Applause'
else
  Play SE 'Buzzer1'
End of Condition

Now for the execution
  - First time I trigger the even,the scene appear
  - When I choose an option... no soucd
  - Second time I trigger the event, I hear the sound corresponding to the previous choice, and the scene appears.
  - When I choose an option,still no sound
  - And so on...

It seems as if the Script and the Condition where run on parrallell processes, or some part of the Event Command where frozen , or... I still don't understand.

Any lead ??

Ah... and... I still don't know how to set a title for the spoiler thing 

 

[Dargor]

your script seems ok. try adding a wait of 1 frame before the conditional branch.

 

[Fustel]

Bingo !!!

Thanks Dargor-sensei  :smile:

 

[Fustel]

One last question...
We know the HOW to resolve the problem, but...

Does anyone know the WHY it happens? ( for the sake of pure academic knowledge :smile

 

[Dargor]

I don't know the exact answer but I think the interpreter stops interpreting an event after a scene change, if the scene change occured in the middle of an event. And if it's the case, then I really don't know why it works when you add a wait.

That's an excellent question.
