In order to wire up the system: script "thing=(readable(owner))" into the joint between the segments of the wire, then, if the energy flows from the geom0-segment to the geom1-segment, then script "(entitybygeomid(thing.geom1)).reflectiveness = (entitybygeomid(thing.geom0)).reflectiveness" for phase-1, script "(entitybygeomid(thing.geom1)).refractiveindex = (entitybygeomid(thing.geom0)).refractiveindex" for phase-2 and script "(entitybygeomid(thing.geom1)).friction = (entitybygeomid(thing.geom0)).friction" for phase-3. But, if the energy flows from the geom1-segment to the geom0-segment, then script "(entitybygeomid(thing.geom0)).reflectiveness = (entitybygeomid(thing.geom1)).reflectiveness" for phase-1, script "(entitybygeomid(thing.geom0)).refractiveindex = (entitybygeomid(thing.geom1)).refractiveindex" for phase-2 and script "(entitybygeomid(thing.geom0)).friction = (entitybygeomid(thing.geom1)).friction" for phase-3.
