Hello, rehashing an old lisp ported by the owner. I would like to add the option to put a light in the center of the room. with an array of high hat/can lights around it.
;;------------------=={ Custom Block Array }==----------------;;
;; ;;
;; Program will generate a rectangular array of a selected ;;
;; block with a specified number of rows and columns, with ;;
;; blocks spaced uniformly and aligned centrally between two ;;
;; window corner points selected by the user. ;;
;; ;;
;; Upon calling the program, the user is prompted to select ;;
;; a block to be arrayed. Following a valid selection, the ;;
;; user is then prompted to specify the number of rows and ;;
;; columns for the array, with the previously entered ;;
;; figures available as default values. ;;
;; ;;
;; A prompt then asks the user whether grid-lines are to ;;
;; be constructed, such grid-lines intersect at the ;;
;; insertion points of each block in the array and extend ;;
;; to the limits set by the selected corner points. ;;
;; ;;
;; The user is then prompted to pick two corner points of an ;;
;; array window, and the selected block is arrayed evenly ;;
;; between these points, with equal spacing. ;;

I added = p4 (polar P1 (angle P1 P2) (/ (distance P1 P2) 2.0)))
trying to set the center of the room using p1 and p2
I added = (command "insert" "light" p4)
I would think that it would work like this,, eventually I would like the option to ask if you want to add a ceiling light or ,, a fan light.. yes or no
Any input please? Nick
