local destination = force.get_spawn_position(surface)
local spaceship_wreck = storage.force_control[entity.force.name].spaceship_wreck
if spaceship_wreck and spaceship_wreck.valid and spaceship_wreck.surface == surface then
destination = spaceship_wreck.position
end
if math.random(15)==1 then CallFrenzyAttack(surface,entity) end
if math.random(25)==1 then
if distance(entity.position,destination)>120 then
CallWormAttack(surface,entity.position,1,20)
end
end
if (not storage.control_e_tick[force.name]) or
(game.tick > storage.control_e_tick[force.name]+60*5) then
unit_follows_player(entity)
end
if distance(entity.position,destination)<30 then
tab_event.state=2
advance_mission_control(tab_event.mission_name,tab_event)
table.remove(storage.monitored_entity,k)
