Adds uncertainty of value meters to object's Z position.

Default value: 0

Legal values: all real numbers

Homeworld effects use cylindrical co-ordinates. LOF (Line Of Fire, as near as I can tell) corresponds to the Z axis. See the picture below for the effect setDeltaLOFDist() can have on an object's position. The object created will have an offset somewhere between (DeltaLOF - DeltaLOFDist) and (DeltaLOF + DeltaLOFDist). This is useful for creating multiple objects with the same create* statement and putting some space between the objects.
