#==============================================================================
# Chest Item Pop-Up 2
#==============================================================================
# Author  : OriginalWij
# Version : 1.2
#==============================================================================

#==============================================================================
# NOTE: The newest version is the ONLY supported version!
#
# v1.2
# - Added Experience popup for event commands
#==============================================================================

#==============================================================================
# To use:
#
# 1) Setup the options in configuration section below
# 2) Turn on the activation switch (defined in configuration section below)
# 3) Add items via event commands like normal
#
# NOTE1: this script will automatically pop-up if activation switch is on!
# NOTE2: turn activation switch OFF to add items WITHOUT popup
# NOTE3: when adding multiple (different) items, insert a WAIT(1) between them
# NOTE4: use WAIT(7) between a message & popup (allows message window to close)
#==============================================================================

#==============================================================================
# To call manually from any scene or from an event script command:
#
# NOTE: For scripters only!
#
#   (useful if using a break-limits script and popping-up 100+ of one item)
#
#   $scene.item_popup(type, amount, index)
#   $scene.item_popup(type, amount, index, add)
#          type : 0 :gold; 1 :items; 2 :weapons; 3 :armor; 4 :experience
#        amount : quantity "gaining"
#         index : item ID (use 0 for gold & experience)
#           add : adds items into inventory if true (optional, default = false)
