RT，需要说明的是，这里的滚动并不是事件中人为的滚动，而是随着主角行走时，画面会发生滚动，但是到接近边缘的时候画面就不会发生滚动。之前我先试着自己算了下display_x还有display_y，但是试出来的值只在一张地图上有用，换了个地图就不管用了。附上脚本吧，这个脚本是用来在角色发生移动的时候，远景向反方向移动，但我希望它在地图不发生滚动的时候能不移动……于是，拜托各位帮个忙，先谢过各位高手啦～

#  Version 1.0
#  Author: modern algebra (rmrk.net)
#  Date: August 2, 2008
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#  Description:
#    This script allows you to set a speed for a parallax to scroll extra
#  when the player is moving. It will scroll in the opposite direction, to 
#  give the illusion of a horizon.
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#  Instructions:
#    To make it so that the parallax will scroll, you must check the box in the
#  map settings for it to scroll, even if you do not want it to scroll 
#  regularly. You can avoid it scrolling regularly by leaving the scroll value
#  at 0. For instructions on setting up the maps, see the CONFIGURABLE REGION
#  at line 49. You can also use this code:
#
#    $game_map.p_scroll_mod = 
# 
#    to set the speed manually in game. It will reset once you leave the map.
