# CHANGE LOGS:
# -----------------------------------------------------------------------------
# 2013.08.19 - Compatibility Patch with Limited Inventory
# 2013.06.27 - Add custom chest name
# 2013.06.01 - Adjust control and GUI
# 2013.05.24 - Finished script
# 2013.05.23 - Started Script
# =============================================================================
=begin

  Perkenalan :
  Script ini bikin kamu bisa buka chest dan mengisi ataupun mengambil barang
  didalamnya seperti game Elder Scroll atau game2 RPG Western lainnya.

  Cara penggunaan :
  Pasang dibawah material namun diatas main

  Gunakan comment pada event dengan format berikut sebelum script call
  <item: id, amount>
  <weapon: id, amount>
  <armor: id, amount>

  Dimana :
  id >> id item tersebut
  amount >> jumlah barang yang ada di chest tersebut

  Setelah ditulis komen, gunakan script call :
  open_chest

  Untuk penamaan chest, kamu bisa menggunakan script call :
  open_chest("Garbage")

  note : komen dalam setiap event hanya dibaca sekali. Pastikan letakin di atas
  ndiri untuk tag2 chest system

  Terms of use :
  Credit gw, TheoAllen. Kalo semisal u bisa ngedit2 script gw trus jadi lebih
  keren, terserah. Ane bebasin. Asal ngga ngeklaim aja. Dan btw, kalo dipake
  untuk komersial, bagi ane keuntungannya juga. Ama gratisan gamenya juga

# Konfigurasi :

module THEO
  module CHEST
    # =========================================================================
    # Vocabs
    # -------------------------------------------------------------------------
      AMOUNT_VOCAB  = "Amount :"    # Vocab untuk kata amount
      ALL_VOCAB     = "All"         # Vocab untuk kategori all
      INV_VOCAB     = "Inventory"   # Vocab untuk inventory
      ST_VOCAB      = "Stash"       # Vocab untuk stash / penyimpanan
    # =========================================================================

    # =========================================================================
      TRIGGER_GAIN_ALL  = :CTRL
    # -------------------------------------------------------------------------
    # Trigger untuk ngambil semua. Semisal kamu nulisin :CTRL, maka semua item
    # akan didapet kalo kamu mencet CTRL + Confirm (z)
    # =========================================================================

    # =========================================================================
      SHOW_AMOUNT_MIN   = 10
    # -------------------------------------------------------------------------
    # Jumlah minimal untuk nampilin window amount. Semisal item yang kamu
    # pilih jumlahnya dibawah nilai tersebut, maka akan dipindah satu2 daripada
    # munculin window amount.
