Hi all,
I wrote the following jess code:
(deffacts initialization
(user-interaction_movement (name john) (position 0) (heading N) (direction
N) (speed 0.5) (time 0))
)
(defrule is-slow
(printout t "here---is slow" crlf)
(user-interaction_movement (name ?user) (position ?p) (heading ?h)
(direction ?d) (speed ?s) (time 0))
(test (<= ?s 1.5))
=>
(printout t "is slow" crlf)
(assert (slow ?user))
)
(reset)
(run)
(facts)
Here is the result:
Jess> (batch test.CLP)
f-0 (MAIN::initial-fact)
f-1 (MAIN::user-interaction_movement (name john) (position 0) (heading N)
(dir
ection N) (speed 0.5) (time 0))
Do you know why "is-slow" rule does not get asserted?
I am using Jess61p2.CLP trial version on win XP.
Thanks,
Leila
