I didnt read everything, but I found this one, which might help:
function get_force_entities(surface, force)
return surface.find_entities_filtered{
force = force.name
}
end
function are_force_players_online(force)
local count = #force.connected_players
return 0 ~= count
end
script.on_event(defines.events.on_player_joined_game, function(event)
local player = game.players[event.player_index]
local force = player.force
local setting_debug = settings.global["protect-offline-forces-debug"].value
if setting_debug then
for _, p in pairs(game.players) do
p.print('Unprotecting force ' .. force.name)
end
end
local setting_indestructible = settings.global["protect-offline-forces-indestructible"].value
local setting_inactive = settings.global["protect-offline-forces-inactive"].value
for _, surface in pairs(game.surfaces) do
for _, entity in pairs(get_force_entities(surface, force)) do
if setting_indestructible then
entity.destructible = true
end
if setting_inactive then
entity.active = true
end
end
end
end)
script.on_event(defines.events.on_player_left_game, function(event)
local player = game.players[event.player_index]
local force = player.force
local setting_debug = settings.global["protect-offline-forces-debug"].value
local setting_indestructible = settings.global["protect-offline-forces-indestructible"].value
local setting_inactive = settings.global["protect-offline-forces-inactive"].value
if not(are_force_players_online(force)) then
if setting_debug then
for _, p in pairs(game.players) do
p.print('Protecting force ' .. force.name)
end
end
for _, surface in pairs(game.surfaces) do
for _, entity in pairs(get_force_entities(surface, force)) do
if setting_indestructible then
entity.destructible = false
end
if setting_inactive then
entity.active = false
end
end
end
end
end)
I am not 100% sure, if deactivating entities is enough regarding polution, but it works fine regarding biters.
