/*
    This Invisable object will do a check and see
    if any pc comes within a radius of this object.

    If the PC has the search skill or is a elf then
    a search check will be made.

    It will create a trapped trapdoor at its own location

    The radius is 10
    The DC to detect and disarm is determined by the tag given to this trigger
    it creates a trapdoor with the first nine letters of its own tag + _plate
    So it would be jw_trap_1_plate, jw_trap_2_plate etc
    If this trigger has local int "triggered" set to true, then it returns;
    The difficulty of spotting the trap is determined by the ninth letter in the tag.
    Eg jw_trap_1 is the easiest jw_trap_5 is the hardest
    The trap that is created has three local variables given to it
    "creator", a string that refers to this trigger.
    "diff", a string that refers to the difficulty, from 1 to 5
    This will determine the DC to disarm the trap, the DC to detect it, and the amount of damage done
    "type", a sting that tells it what type of trap it is
    The type is determined by the tenth letter of the tag of this trigger
    eg jw_trap_1_f - f is the 11th letter and means that this is a fire trap
    f=fire
    s=spikes
    a=acid
    e=elec
    n=negative
    c=cold
    o=sonic
