Using the sandbox ruleset, add this to script.lua
function coast_only(tile, resource)
isOK = false
for t in tile:square_iterate(1) do
class = t.terrain:class_name()
if class == "Oceanic" then
isOK = true
break;
end
end -- for tile:square_iterate
if not isOK then
edit.remove_extra(tile, resource)
end
end
function coasts_only_callback()
for tile in whole_map_iterate() do
local resource = "Ivory"
if tile:has_extra(resource) then
coast_only(tile, resource)
end
end -- for whole_map_iterate
return false
end
signal.connect("map_generated", "coasts_only_callback")
When run, chat log shows this many times
in dbv_isset() [../../freeciv-3.0.0/utility/bitvector.c::122]: assertion 'pdbv->vec != ((void*)0)' failed.
Please report this message at https://osdn.net/projects/freeciv/ticket/
Without edit.remove_extra(tile, resource) the problem doesn't happen.
