Simple Item menu EDIT

[Zexion]

Well Im using the default item menu, and I just want to know one thing. How do I make items show by type? Like list all the weapons first, then items, then accessories etc.

The default item menu can be found by locating 'Window_Item' in your list of scripts. Scroll down until you find 'def refresh'. The key part that you want to look at is this:

Spoiler: ShowHide

    @data = []
    # Add item
    for i in 1...$data_items.size
      if $game_party.item_number(i) > 0
        @data.push($data_items[i])
      end
    end
    # Also add weapons and items if outside of battle
    unless $game_temp.in_battle
      for i in 1...$data_weapons.size
        if $game_party.weapon_number(i) > 0
          @data.push($data_weapons[i])
        end
      end
      for i in 1...$data_armors.size
        if $game_party.armor_number(i) > 0
          @data.push($data_armors[i])
        end
      end
    end

The game will first check for items (potions, antidotes, etc), then weapons, then armors. Because 'Window_Item' is used in battles as well, the line

unless $game_temp.in_battle

is needed. This way, it won't draw your weapons and armors when in battle--only your potions and key-items.

Accessories, shields, clothes, and helms are all considered as Armor. By using '$data_armors[index].kind', you can change the order of what is drawn first. So in your example, it would look like this:

Spoiler: ShowHide

    @data = []
    #Adds weapons to the list
    unless $game_temp.in_battle
      for i in 1...$data_weapons.size
        if $game_party.weapon_number(i) > 0
          @data.push($data_weapons[i])
        end
      end
    end
    # Adds items to the list
    for i in 1...$data_items.size
      if $game_party.item_number(i) > 0
        @data.push($data_items[i])
      end
    end
    # Adds accessories to the list
    unless $game_temp.in_battle
      for i in 1...$data_armors.size
        # 0 = shield, 1 = helm, 2 = body, 3 = accessories
        if $game_party.armor_number(i) > 0 and $data_armors[i].kind == 3
          @data.push($data_armors[i])
        end
      end
    end
    # Continue on with the list...

Thanks for the info, but now I need to know another thing How do I add a window with a description of the item, because the default one is too high and is difficult to work with.

[KK20]

Think you can explain that a bit more for me? From what I'm understanding, you're saying that the default 'Window_Help' is not working out for you. What more do you need other than the item's description? Obviously you'll have to create a new type of window, but because I don't know what you want, I don't know where I'd begin. 

[Zexion]

Yes sorry for being so vague, but Well the default window is just placed at the top of the screen, but I want it to be at the bottom.
I guess what I am asking for is if you could remake me the help/description box, but make it easier to move around the screen, because right now if I edit the default it acts wierd and starts messing up the windowskin for some reason.

This is the problem:

This is what I want:

Yes I am using a resolution script :p but if you make me a normal window that shows the description, I will know how to move it around and stuff.

[KK20]

So...all I did was copy 'Window_Help' a bit and made a new type of Window class designed specifically for item descriptions. I only went ahead and changed 'Scene_Item' to incorporate this new window. You can just change the values of how the window is set up to fit your needs.

#==============================================================================
# ** Window_Item_Desc
#------------------------------------------------------------------------------
#  This window shows an item's description.
#==============================================================================

class Window_Item_Desc < Window_Base

  #--------------------------------------------------------------------------
  def initialize
    #(x, y, width, height)
    super(100, 300, 640, 64)
    self.contents = Bitmap.new(width - 32, height - 32)
  end
  #--------------------------------------------------------------------------
  # * Set Text
  #  text  : text string displayed in window
  #  align : alignment (0..flush left, 1..center, 2..flush right)

  def set_text(text, align = 0)
    # If at least one part of text and alignment differ from last time
    if text != @text or align != @align
      # Redraw text
      self.contents.clear
      self.contents.font.color = normal_color
      self.contents.draw_text(4, 0, self.width - 40, 32, text, align)
      @text = text
      @align = align
      @actor = nil
    end
    self.visible = true
  end
end
#==============================================================================

#==============================================================================

class Scene_Item
  #--------------------------------------------------------------------------
  # * Main Processing
  #--------------------------------------------------------------------------
  def main
    # Make help window, item window
    @item_window = Window_Item.new
    @help_window = Window_Item_Desc.new
    # Associate help window
    @item_window.help_window = @help_window
    # Make target window (set to invisible / inactive)
    @target_window = Window_Target.new
    @target_window.visible = false
    @target_window.active = false
    # Execute transition
    Graphics.transition
    # Main loop
    loop do
      # Update game screen
      Graphics.update
      # Update input information
      Input.update
      # Frame update
      update
      # Abort loop if screen is changed
      if $scene != self
        break
      end
    end
    # Prepare for transition
    Graphics.freeze
    # Dispose of windows
    @help_window.dispose
    @item_window.dispose
    @target_window.dispose
  end
end

I am curious to know what you meant in 'editting the default', saying how the windowskin gets weird.

[Zexion]

Thank you I will try this out right now!

And by it looking wierd, I mean I edited the part in window_help that says

def initialize
    super(0, 0, 640, 64)
    self.contents = Bitmap.new(width - 32, height - 32)
  end

To

def initialize
    super(0, 0, 320, 32)
    self.contents = Bitmap.new(width - 16, height - 16)
  end

Which is exactly half because the resolution is exactly half. This is usually what I do, but this time it made the window look like:
