PokéCommunity is breaking codes. For copying scripts at PokéCommunity: Click Thread Tools, and then Show Printable Version, and copy that instead.

#===============================================================================
# * Scene Positioner - by FL with some Poccil scripts
#===============================================================================
#
# This script is for RPG Maker XP. This is a scripter tool for helping
# scripters making scenes. 
# 
# It allows reading sprites coordinates in a windows or at txt log and even
# changing sprites positions/visibility. It is compatible with Pokémon
# Essentials and Crazyninjaguy Mouse Script, you can even easily adapt
# other mouse scripts.
# 
#===============================================================================
#
# To this script works, put it above main and below other scripts. 
#
# At every scene that you wish it working, put the line
# '@scenePositioner = ScenePositioner.new(@sprites)' before update loop
# where '@sprites' is a hash with all sprites/windows that you wish that
# this script affect. Put the line '@scenePositioner.update' when you
# update the graphics and the input at the scene. After you dispose the
# sprites, put the line '@scenePositioner.destroy'. If you wish to
# display ox/oy/rotation when displaying coordinates, just use 
# '@scenePositioner = ScenePositioner.new(@sprites,true)' instead of 
# '@scenePositioner = ScenePositioner.new(@sprites)'.
#
# For obtaining the selected sprite coordinates, a list of all sprites that
# you moved, a control list and even printing these data in a txt file (except
# the control list), just press Q.
#
# For allowing pause button to pause the game, wrap every update lines, 
# except 'Graphics.update', 'Input.update' and '@scenePositioner.update' at
# 'if [email protected]'.
#
# For making Crazyninjaguy script working at game that doesn't uses
# Pokémon Essentials, just put the line '$ResizeFactor=1' before line 
# 'module Resolution'.
