If you only want to match the "dirty" fact that has the same values as
a given "position" fact, then you have to use the same
variables to represent those values
(defrule have-dirty
(position (x-position ?xp) (y-position ?yp)
(dirty (x-pos ?xp) (y-pos ?yp)
=>
...
Please give the manual a close reading, because there are many small
examples that teach this sort of thing indirectly. For example, see
the first example in section 2.8.6 of the Jess 6.0b1 manual, which is
a perfect example of what you're doing here.
