# Gamepad Extender VX v1.0a (7/25/12)
# by Lone Wolf
#------------------------------------------------------------------------------
# This allows scripters to utilize the extra buttons on modern
# XInput-compatible gamepads. It requires DirectX 9.0 or later and
# an XInput compatible gamepad. Incompatible pads will default to
# using the standard Input module functionality.
#
# This is not a plug-and-play script.
#
# Instructions:
# - Paste in the Materials section.
# - Use the PadConfig section to specify button differences between
# Gamepad and Keyboard (optional but recommended)
# (Replace direct button calls in your scripts (and the defaults) with
# PadConfig calls or these will do nothing.)
#------------------------------------------------------------------------------
# Command Reference:
#------------------------------------------------------------------------------
# All calls to extended buttons on Pad 1 can be made through the Input module.
# Pass WolfPad::BUTTON for pad calls, Input::BUTTON for keyboard calls.
# When using multiple pads, send calls directly to WolfPad with pad number
# as the final parameter.
#
# The current list of mappable buttons is as follows:
#
# A, B, X, Y - XBOX 360 standard face buttons.
# L1, L2, R1, R2 - Four triggers (LB, LT, RB, RT)
# SELECT, START - Back and Start buttons
# L3, R3 - Clickable Analog buttons
#
# UP, DOWN,
# LEFT, RIGHT - D-Pad buttons
#
# NON-STANDARD MAPPINGS WILL DO NOTHING without a compatible gamepad.
# To that end, use calls to PadConfig to remap non-standard keys into
# the standard domain where possible.
#
# for example: "Input.trigger?(PadConfig.page_down)"
# will return WolfPad::R1 if a gamepad is plugged in, but Input::R otherwise
#
# Analog values can be referenced with the following commands:
# left_stick
# right_stick
# left_trigger
# right_trigger
#
# Directional values of analog sticks can be referenced with these:
# lstick4
# lstick8
# rstick4
# rstick8
#
# Controller vibration can be accessed with these:
# vibrate(left_motor, right_motor, frame_duration)
# set_motors(left_motor, right_motor)
#
#
# All functions take an optional gamepad ID as their final parameter.
#------------------------------------------------------------------------------
# Terms of Use:
#------------------------------------------------------------------------------
# If you use it, give credit. With a few caveats:
#
# This is an alpha version of a script in development.
# I make no guarantees of compatibility with other scripts.
#
# This is a VX port of an RGSS3 script. Some features may behave differently,
#
# This script was posted at the official RPG Maker forums.
# Do modify or redistribute this script by itself, though you may
# include a configured version with your own script demos provided
# you include this header in its entirety.
