#------------------------------------------------------------------------------#
#  Galv's Event Spawn Timer
#------------------------------------------------------------------------------#
#  For: RPGMAKER VX ACE
#  Version 1.1
#------------------------------------------------------------------------------#
#  2013-02-24 - Version 1.1 - added script call to purge specified timer
#                           - changed name to Event Spawn Timer
#  2013-02-23 - Version 1.0 - release
#-------------------------------------------------------------------------------
#  This script allows you to set respawn timers for events and have them auto-
#  matically change a switch or self switch when their timer expires.
#
#  As the timer checks are made during the event movements, obviously these
#  switches will not be changed until the player gets close enough. This was my
#  idea at keeping any lag or checking billions of things at once down. Use the
#  other script calls to force check if you require it to work differently.
#-------------------------------------------------------------------------------

#-------------------------------------------------------------------------------
#  SCRIPT CALL in EVENT script box
#-------------------------------------------------------------------------------
#  set_spawn(map_id,event_id,time)   # set which map, event and how many seconds
#                                    # before respawn. Setting map or event id
#                                    # to 0 will use current map and event the
#                                    # script call was done in.
#-------------------------------------------------------------------------------
#  EXAMPLES:
#  set_spawn(1,2,20)    # Event 2 on map 1 will respawn in 20 seconds from now
#  set_spawn(0,0,200)   # The event this call is in will respawn in 200 seconds
#-------------------------------------------------------------------------------

#-------------------------------------------------------------------------------
#  SCRIPT in a MOVE ROUTE script
#-------------------------------------------------------------------------------
#  do_respawn?(switch,status)   # This will check if the time is elapsed and
#                               # if so it will change a switch or self switch
#                               # to the status (true or false).
#-------------------------------------------------------------------------------
#  EXAMPLES:
#  do_respawn?("A",false)    # Turns self switch A OFF if time elapses
#  do_respawn?(1,true)       # Turns switch 1 ON if time elapses
#-------------------------------------------------------------------------------

#-------------------------------------------------------------------------------
#  SCRIPT CALLS in EVENT script box
#-------------------------------------------------------------------------------
#  purge_respawn_timers            # Remove all activated timers
#  purge_timer(map_id,event_id)    # Remove specified active timer from list
#
#  do_all_respawn(switch,status)   # Checks all events with respawn timers and
#                                  # changes all their switches to true or false
#
#  do_map_respawn(map_id,switch,status)  # Same as above but only for the map
#                                        # you designate with map_id
#
#  do_e_respawn(map_id,event_id,switch,status)  # Same as above but check a
#                                               # specific event on a map
#
#  # These calls can be made anywhere to check and affect those events.
#-------------------------------------------------------------------------------

#-------------------------------------------------------------------------------
#  SCRIPT for CONTROL VARIABLES
#-------------------------------------------------------------------------------
#  respawn_time(map_id,event_id)    # Get amount of time left until respawn for
#                                   # an event. Can use 0,0 to check the event
#                                   # and map the control variable is used on.
