module Galv_Riders

#------------------------------------------------------------------------------#  
#  SETUP OPTIONS
#------------------------------------------------------------------------------#

  MOUNTS = [:boat,:ship]  # Which vehicles you want to be mountable only these
                          # vehicles will use mounts, others will not
  
#------------------------------------------------------------------------------#
  POS = {} # Don't touch this
#------------------------------------------------------------------------------#

  # Below is to specify positioning of the rider graphic for each vehicle and
  # to specify if it uses a different charactersheet or not. These options are:
  # [x offset, y offset, charactersheet extension, horse]

  POS[:boat] = [6,-12,"", true]
  POS[:ship] = [0,-9,"_ship", false]
  POS[:airship] = [0,0,"",false]

#------------------------------------------------------------------------------#
#  EXPLANATION
#------------------------------------------------------------------------------#

  # x offset - will offset the rider horizontally that many pixels
  # y offset - will offset the rider vertically that many pixels
  # charactersheet extension - To use a different charactersheet for the rider.
  #       If this is set to "_rider" and the group leader uses "Actor4" charset
  #       then it will look for "Actor4_rider" charset to use when mounted on
  #       that vehicle. Leave this option as "" to use the actor's charset.
  # horse - when facing down, the actor's graphic will appear under the vehicle
  #         this was made with the horse from the "animal" charset in mind.
