# TriggeredZonePropertyChanger/Code

Actor >> TriggeredZonePropertyChanger

    //   This trigger allows mappers to change some of the zone properties using a trigger.
    //   The specific case this class was written for was to enable a switchable "escalator"
    //   zone to be created, where the escalator could move in two directions at once.
    //
    //   The Zone property changer is a one way assignment of values.  It will change the
    //   properties of its target zone once.  In order to revert them back to their original
    //   values an additional Zone property changer object would be required (possibly triggered
    //   by a round robin trigger).
    //
    //   Version By  Description
    //   ------- --- -------------------------------------------------------------------------
    //   1.00    DML Created for Pitboy from the UT Editing fourm.
