#  Version: 1.0
#  Author: modern algebra (rmrk.net)
#  Date: April 5, 2010
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Description:
#    This script allows the player to take a screenshot of any area in the game
#   that he/she wants. Useful for sharing achievements I suppose.
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Instructions:
#    All you need to do is set which button you want to use for taking
#   screenshots with at line 31, and set the destination folder for screenshots
#   at line 33.
#    If you want to force a screenshot, you can put this code in a call script:
#       $scene.take_screenshot

#  Summary of Changes:
#    new constant - MA_SCREENSHOT_BUTTON, MA_SCREENSHOT_PATH
#    aliased method - update

$scene.take_screenshot 을 스크립트로 이벤트추가 해주심 됩니다.(전체 단축키스크립트를 이용해 단축기로도 스샷 가능
