#===============================================================================
# // Face Frames
# Author: Rikifive
# Engine: RPG Maker VX Ace
# Version: 1.1 (2020-10-03)
#
#===============================================================================
# DESCRIPTION
#===============================================================================
# This script draws frames on top of faces displayed in message boxes, menus etc.
#
# No work required, the frames are drawn using windowskin.
# ("Window" image in the Graphics\System folder, that is)
#
# You can also make your own custom 96x96 frame images and switch between these
# on the fly by adjusting in-game variable.
#
# Also, by adding this script you'll be able to draw window frames wherever
# you want. To draw a frame in window contents, use this draw method:
#
# > draw_window_frame(x, y, width, height)
#
# This will draw window frame in specified coordinates and dimensions,
# using current windowskin.
#
#===============================================================================
# INSTRUCTIONS
#===============================================================================
# ► SCRIPT DIFFICULTY: ★☆☆☆☆
#   This script is basically Plug & Play if you intend to use the windowskin.
#
# -=> Place script(s) below ▼ Materials; above ▼ Main Process
#
# If you want to use custom images for frames:
# - Draw a frame with the same dimensions as a single face (96x96)
# - Name the file: "frame" OR "frame0", "frame1", "frame2"...(see configuration)
# - Put it/these in PROJECT_NAME\Graphics\Faces
# - Configure the script below to your needs

# CONFIGURATION
#===============================================================================
module RK5_FRAMES
  # PIXELS to cut out from each side of the face, so that it doesn't leak
  # through the frame (default windowskin's borders are 6px thick)
  FACE_OFFSET = 6
  
  # Whether to use a special image or automatically draw from the Windowskin
  # true: Requires a 96x96 image titled "frame" in [ Graphics\Faces ]
  # false: No images required, windowskin will be used.
  USE_IMAGE = false
  
  # Whether you want to use more than one frame image (when above is true)
  # true: /!\ Requires 96x96 images titled "frame0", "frame1" and so on instead.
  #       The number after "frame" will correspond to the in-game variable.
  #       Example: Setting $game_variables[ID] to 15 will draw "frame15".
  # false: Leave default and use "frame" only.
  USE_VARIANTS = false
  
  # The variable to use for specifying the frame image (only if above is true).
  # Otherwise set it to whatever number, as it won't impact the game in any way.
