Jump to nearest empty?

[dale walton]

How is move to the nearest occupied space done? Step / variable length Hop over occupied sites to the first Empty...

I tried
(move Slide
           (between ifnot (is In (between) (sites Empty)) ))
           (to ifis Empty atto))
)

But this also allowed moves to the occupied intermediate positions.

I tried
(move Hop
   (between
      (range 0 9)
      ifnot (is In (between) (sites Empty)) )
    )
    (to ifis Empty atto))
)
But this didn't work at all (maybe the board was too small?).
Leaving the range out only allowed single hops.

In the current version you can do

Code:

(.... 
    (equipment {
        (board ...)
        (piece "Disc" Each (move (from) (to (sites LineOfSight Piece at:(from)))))
    }) 
    (rules
        (play (forEach Piece))
        (end (if ....) )
    )
)

Sorry for my typo. I meant I want to move not to the nearest occupied space, but to the nearest unoccupied space ... My bad.

Ok so just to be sure before to answer, if we look a single line with

P O1 O2 O3 U1 U2 U3 O4 U5

where P is your piece, O are the occupied spaces (by friend or enemy pieces), U the unoccupied space.
you want P to move to the nearest unoccupied space, so you just want to hop O1 O2 O3 and go to U1? or not?

Correct. 
And on a ray with the adjacent space unoccupied, it should go adjacent.
And If a ray has no unoccupied space, it cannot move there.

Thanks to your question I found a bug in our hop move and fixed it, so thank you ;)

The description for what you describe (for example for a board of size 16 and for a piece which is here a ball) is

Code:

(piece "Ball" Each
    (move Hop
        (between
           (range 0 16)
           if:(not (is Empty (between)))
        )
        (to if:(is Empty (to)))
    )
)


(rules 
    ...
    (play (forEach Piece))
    ...
)

But that will work correctly only when we will release the next version.
