# • Description:
#------------------------------------------------------------------------------
#  A system of sensor, which allows for differents types of forms of the events,
# to "fell" the presence of player.
#==============================================================================
# • How to use: Use the commands on conditions of events.
#------------------------------------------------------------------------------
#  a : area of squares(tiles) in who the sensor it will be activated.
#  b : ID of the event. If not defined, is the local event. For default,
# is the local event.
#------------------------------------------------------------------------------
# 1 * The first type of sensor, is the sensor of the area. The command to use
# this type of sensor is the : sarea?(a, b)
# 2 * Sensor who checks if it's in down of the event: sfront?(a, b)
# 3 * Sensor who checks if it's in up of the event: sago?(a, b)
# 4 * Sensor who checks if it's in left of the event: sleft?(a, b)
# 5 * Sensor who checks if it's in right of the event: sright?(a, b)
# 6 * Sensor who checks in form of the cross: scross?(a, b)
# 7 * Sensor who checks if it's only in vision of the event: svision?(a, b)
# 8 * Sensor who checks if it's about the event: sabout?(b)
# 9 * Sensor who checks if it's just behind of the event : sbehind?(a, b)
# 10 * Sensor who checks if it's just the left of event: vleft?(a, b)
# 11 * Sensor who checks if it's just the right of event: vright?(a, b)
# 12 * Sensor who checks if it's in the left-upper of event. dsleft?(a, b)
# 13 * Sensor who checks if it's in the right-upper of event. dsright?(a, b)
# 14 * Sensor who checks if it's in the left-bottom of event. dileft?(a, b)
# 15 * Sensor who checks if it's in the right-bottom of event. diright?(a, b)
# 16 * Sensor who checks if it's in all side on diagonal. diagonal?(a, b)
# 17 * Sensor who checks if it's in form of circle. scircle?(a, b)
# 18 * Sensor who checks if it's vision diagonal according with event. vdiagonal?(a, b)
#------------------------------------------------------------------------------
# * Attention, the item 2 to 5 are static, ie, will fixed
# independently of directions in who the events stay
# * The items 7, 9, 10, 11: In a line straight
