Window not updating

[Ellie]

I'm making a mining system, and everything works except one window, which doesn't update.

Here's what I have so far: (do not use on pain of death/monkeyrape)

class Scene_Mining
  
  def main
    @hud = Sprite.new
    @hud.bitmap = RPG::Cache.minigame('mining_hud')
    @over = Sprite.new
    @over.bitmap = RPG::Cache.minigame('mining_overlay')
    @over.z = 9995
    
    @help = Window_Help.new
    @help.x = 57
    @help.y = 67
    @help.z = 9998
    @help.width = 420
    
    $game_variables[45] = 20 if $game_variables[45] == 0
    $game_variables[21] = 1 if $game_variables[21] == 0
    
    @rockwin = Window_Rocks.new
    
    @rockwin2 = Window_MineBase.new
    
    @toolbar = Window_Toolbar.new
    
    $power = 0
    
    @rockwin3 = Window_MineBar.new
    
    # Setup rocks
    amnt = $game_variables[21] # mining rank
    amnt = 1 if amnt == 0
    
    @rand = rand(amnt)
    @rand += 1
    case @rand
    when 1
      @rock = 'coal'
    when 2
      @rock = 'iron'
    when 3
      @rock = 'lead'
    when 4
      @rock = 'gold'
    when 5
      @rock = 'mith'
    end
    
    @help.visible = false
    
    Graphics.transition
    loop do
      Graphics.update
      Input.update
      update
      if $scene != self
        break
      end
    end
    Graphics.freeze
    
    @hud.dispose
    @over.dispose
    @rockwin.dispose
    @rockwin2.dispose
    @help.dispose
    @rockwin3.dispose
  end
  
  def update
    
    @hud.update
    @rockwin.update
    @rockwin2.update
    @rockwin3.update
    @help.update
    
    if @restart == true
      @restart = false
      $scene = Scene_Mining.new
      return
    end      
      
    if Input.trigger?(Input::UP)
      $power += 2 unless $power >= 50
    else
      $power -= 1 unless $power <= 0
    end
      
    if Input.trigger?(Input::C)
      if $game_variables[34] <= 0
        @help.visible = true
        @help.set_text('You are too tired to mine right now.')
        @help.visible = true
        return
      end
      
      if $power <= 30
        @help.visible = true
        @help.set_text('You hit the rock with your pickaxe, but not powerful enough to break it.')
        @restart = true
      elsif $power >= 40
        @help.visible = true
        @help.set_text('You hit the rock with your pickaxe.')
        @help.set_text('You use too much power; the rock crumbles to dust.')
        @restart = true
      else
        swing
      end
      
    end
    
    if Input.trigger?(Input::B)
      $scene = Scene_Map.new
    end
      
    levelup if $game_variables[20] >= $game_variables[45]
      
  end
    
  def levelup
    @help.visible = true
    $game_variables[21] += 1
    $game_variables[45] *= 1.75
    $game_variables[45] = $game_variables[45].ceil
    $game_variables[20] = 0
    $fmin = $game_variables[34] = 100
    @help.contents.clear
    @help.set_text('Your mining rank is now ' + $game_variables[21].to_s + '!')
  end
  
  
  def swing
    @help.contents.clear
    @help.visible = true
    @help.set_text('You swing your pickaxe at the rock.')
    
    $game_variables[20] += 5 # temp
    
    @restart = true
  end
  
end

Not the best script in the world, but it should work, as far as I can see. The broken window is @rockwin3, or:

class Window_MineBar < Window_Base
  def initialize
    super(44-16,112-16,24+32,245+32)
    self.contents = Bitmap.new(width - 32, height - 32)
    self.z = 9990
    refresh
  end
  def refresh
    self.contents.clear
    self.contents.draw_hp_picture_vertical(0, 0, $power, 50, 'mining_back', 'mining_front')
  end
end

The HP bar doesn't update here. The script for the HP bar:

class Bitmap
  def draw_hp_picture_vertical(x, y, min, max, background, bar)
    background = RPG::Cache.picture(background)
    bar = RPG::Cache.picture(bar)
    background_rect = Rect.new(0, 0, background.width, background.height)
    h = bar.height * min / max
    bar_rect = Rect.new(0, 0, bar.width, h)
    self.blt(x, y, background, background_rect)
    self.blt(x, y+bar.height-h, bar, bar_rect)
  end
end

Anyone got any ideas?

It IS updating, just not refreshing.  You need to refresh the window by calling refresh.

Ah thanks, that works. (Why do I get the feeling I've asked this before?)
