Details:
While SLF's can already do almost anything, tasks like reliably finding out
the exact movement/vision range of a unit or how many movement points are
needed to reach a given location are still practically impossible. However,
if [filter_radius] could take a [movement_costs] tag which would specify how
many "points" it takes for the radius to expand to a given hex, these would
become doable.
For example, this would store the farthest away locations that side 1 can
reach (to attack):
[store_unit]
[filter]
side=1
[/filter]
kill=no
variable=units
[/store_unit]
{FOREACH units i}
[store_locations]
find_in=locs
[or]
[and]
x,y=$units[$i].x,$units[$i].y
radius="$($units[$i].moves + 1)"
[filter_radius]
[insert_tag]
name=movement_costs
variable=units[$i].movement_costs
[/insert_tag]
[/filter_radius]
[/and]
[not]
x,y=$units[$i].x,$units[$i].y
radius=$units[$i].moves
[filter_radius]
[insert_tag]
name=movement_costs
variable=units[$i].movement_costs
[/insert_tag]
[/filter_radius]
[/not]
[/or]
variable=locs
[/store_locations]
{NEXT i}
As a simpler example, this SLF could be used to store the locations onto
which overflowing lava should expand to, if you'd want it to expand twice as
fast onto cave floor than onto rockbound cave:
terrain=Ql*
radius=2
[filter_radius]
[movement_costs]
flat=1
cave=1
hills=2
[/movement_costs]
[/filter_radius]
Of course, the tag could be named [radius_costs] too. I'm assigning to
Sapient since this is your area of expertise; feel free to unassign if you're
not interested.
