Previous Scene

[Gammastar]

One thing I'm having trouble with is figuring out an EASY way to determine the previous scene. Maybe it's obvious, and I'm just clueless, but are there any suggestions? (-_- I think I used to know how to do this too...)

In the initialize of the new scene you can add a parameter so you know what the last scene is.

class Scene_Test
  def initialize(last_scene = 'Scene_Title')
    @last_scene = last_scene
  end

  def main
    Graphics.transition
    loop do
      Graphics.update
      Input.update
      update
      break if $scene != self
    end
    Graphics.freeze
  end
  
  def update
    if Input.trigger?(Input::B)
      $scene = eval(@last_scene).new
    end
  end
end

The last scene would be a string. So when you say create the instance of this class.

$scene = Scene_Text.new('Scene_Whatever')

But for some reason I think SephirothSpawn just answered a question about this recently so his answer probably makes a bit more sense than mine. Found it:

The way his works is because at the time of the new scene is constructed the previous scene has not yet been changed. I like his answer better no need to even know what the current scene is with his answer.

class Scene_Test
  def initialize
    @last_scene = $scene.class
  end

  def main
    Graphics.transition
    loop do
      Graphics.update
      Input.update
      update
      break if $scene != self
    end
    Graphics.freeze
  end

  def update
    $scene = @last_scene.new if Input.trigger?(Input::B)
  end
end

Good luck with it Gammastar! :thumb:

I can see how it works, but it's not good for my purposes, since you can't change from Scene_Map to Scene_Map... oh well, thanks anyway.

Hmm I'm curious as to why would you want to change to the same scene? In Scene_Map the only reason I can think of would be moving the player or reseting events? The reason however it does not change is because it doesn't break the loop in main.

break if $scene != self

Because it technically is the same scene. What you'll need for this occassion is the addition of a boolean that if true will break.

class Scene_Test
  def initialize
    @break = false
    @last_scene = $scene.class
  end

  def main
    Graphics.transition
    loop do
      Graphics.update
      Input.update
      update
      break if $scene != self || @break
    end
    Graphics.freeze
  end

  def update
    if Input.trigger?(Input::B)
      $scene = @last_scene.new 
      @break = true
    end
  end
end
