Instructions

Nothing much to say, you just need to paste it in a new window above main.

How do I display the actors bars only?

  #--------------------------------------------------------------------------
  # * Draw Slant Bar(by SephirothSpawn)
  #--------------------------------------------------------------------------
  def draw_slant_bar(x, y, min, max, width = 152, height = 6,
      bar_color = Color.new(150, 0, 0, 255), end_color = Color.new(255, 255, 60, 255))
    # Draw Border

        self.contents.fill_rect(x + i + j, y + height - j, 1, 1, Color.new(r, g, b, a))
      end
    end
  end
end


class Window_BattleStatus < Window_Base

  def refresh
    self.contents.clear
    @item_max = $game_party.actors.size
    for i in 0...$game_party.actors.size
      actor = $game_party.actors[i]
      actor_x = i * 160 + 4
      draw_slant_bar(actor_x, 55, actor.hp, actor.maxhp, 120)
      draw_slant_bar(actor_x, 88, actor.sp, actor.maxsp, 120, 6, bar_color = Color.new(150, 0, 150, 255), end_color = Color.new(0, 0, 255, 255))

        self.contents.draw_text(actor_x, 96, 120, 32, "LEVEL UP!")
      else
        draw_actor_state(actor, actor_x, 96)
      end
    end
  end
end

How do I make the enemy bars appear when the weapon has an element assigned?

Replace the code for Window_EnemyHP with this one:

Code:

class Window_EnemyHP < Window_Base
  
  def initialize
    super(0, 0, 640, 480)
    self.contents = Bitmap.new(width - 32, height - 32)
    self.opacity = 0
    refresh
  end
  
  def refresh
    self.contents.clear
    for i in 0...$game_troop.enemies.size
      @enemy = $game_troop.enemies[i]
      @percent = (@enemy.hp * 100) / @enemy.maxhp
      for i in 0...$game_party.actors.size
        if $data_weapons[$game_party.actors[i].weapon_id].element_set.include?(17)
          unless @enemy.hp == 0
            draw_slant_bar(@enemy.screen_x - 55, @enemy.screen_y - 10, @enemy.hp, @enemy.maxhp, width = 75, height = 6, bar_color = Color.new(150, 0, 0, 255), end_color = Color.new(255, 255, 60, 255))
            self.contents.draw_text(@enemy.screen_x - 39, @enemy.screen_y - 22, 100, 32, "#{@percent}" + "%")
          end
        end
      end
    end
  end
end

Now in this line:
if $data_weapons[$game_party.actors[i].weapon_id].element_set.include?(17)

change the 17 with the elements id you want to use to make the bars show up.
Now when you have a weapon equiped with the element 17, the bar shows up.

How do I display the enemy's name?

After the code:

Code:

self.contents.draw_text(@enemy.screen_x - 39, @enemy.screen_y - 22, 100, 32, "#{@percent}" + "%")

add this line:

Code:

self.contents.draw_text(@enemy.screen_x - 45, @enemy.screen_y - 42, 100, 32, "#{@enemy.name}")

How to add outline around the enemies name

Just replace Window_EnemyHP with this one:

Code:

class Window_EnemyHP < Window_Base
  
  def initialize
    super(0, 0, 640, 480)
    self.contents = Bitmap.new(width - 32, height - 32)
    self.opacity = 0
    refresh
  end
  
  def refresh
    self.contents.clear
    for i in 0...$game_troop.enemies.size
      @enemy = $game_troop.enemies[i]
      @percent = (@enemy.hp * 100) / @enemy.maxhp
      unless @enemy.hp == 0
        draw_slant_bar(@enemy.screen_x - 55, @enemy.screen_y - 10, @enemy.hp, @enemy.maxhp, width = 75, height = 6, bar_color = Color.new(150, 0, 0, 255), end_color = Color.new(255, 255, 60, 255))
        self.contents.font.color = Color.new(0,0,0)
        self.contents.draw_text(@enemy.screen_x - 37, @enemy.screen_y - 24, 100, 32, "#{@percent}" + "%")
        self.contents.draw_text(@enemy.screen_x - 43, @enemy.screen_y - 44, 100, 32, "#{@enemy.name}")
        self.contents.font.color = normal_color
        self.contents.draw_text(@enemy.screen_x - 45, @enemy.screen_y - 42, 100, 32, "#{@enemy.name}")
      self.contents.draw_text(@enemy.screen_x - 39, @enemy.screen_y - 22, 100, 32, "#{@percent}" + "%")
    end
  end
end
end
