A FloorWire attempts to make a wire from two of its properties: FloorWire.From and FloorWire.To, which both need to be set to a BasePart. It sometimes goes through bricks but the majority of the time it works fine. It starts at From's center and goes to To's center. Which side of each one it goes into depends on the BaseParts's positions. It chooses the fastest route.
A decimal number between 0 and 1, through which you can control how far all of the decals are along the wire.
