   Map Popups  (v.1.0)

   made by: Silverwind (Metaclaw)
-----------------------------------------------------------------------


 Instructions:

 1) To show some text above an event, add a script command, saying:
    text = "place your text here"
    popup(text)

 2) To show an icon in the popup, add a script command, saying:
    text = "place your text here" *
    icon = "the icon's name" **
    popup(text, icon)

 3) To automatically get an Armor/Weapon/Item/Skill icon-name,
    use :
    icon = get_icon_name(type, id)

    where type is either:
    'Armor' or 'Weapon' or 'Item' or 'Skill'
    and id is the number of the armor/item/etc

   Notes:
   *  To show only an icon, set the text to ""
   ** The icon-name should not include ".png", ".jpg" etc.
      Please use "my_icon" instead of "my_icon.png"
