#  Galv's Region Effects
#------------------------------------------------------------------------------#
#  For: RPGMAKER VX ACE
#  Version 1.2
#  Credit to Yanfly for his event spawning method
#------------------------------------------------------------------------------#
#  2012-10-09 - Version 1.2 - code tweak that may reduce lag on low-end pc's
#  2012-09-16 - Version 1.1 - now compatible with Yanfly's spawn events
#  2012-09-15 - Version 1.0 - release
#------------------------------------------------------------------------------#
#  Designed to activate effects when regions are stood on.
#  An effect can include:
#    - Sound Effect
#    - An event that appears at the player's location
#    - Activating a common event
#
#
#  INSTRUCTIONS:
#  1. Copy image from /Graphics/Characters/!Other-specials.png to your project
#  2. Copy the map from this demo into your game.
#        - this map has events set up for the pre-made effects
#  3. Check the map ID of the map you copied in your game
#  4. Change the SPAWN_MAP_ID number to this map ID
#  5. Change REGION_EFFECT_SWITCH to a switch you are not using in your game.
#  6. Add some regions to your map to test.
#

Eso fue todo.

Aconsejo descargar la demo ya que para utilizarlo es un
proceso bastante complicado.

Estaba tratando de hacer uno igual pero no tenia idea de como
gracias por postearlo...
