When a combat robot expires and is targeting an artillery wagon, it will now explode. This is a work around for a factorio bug where combat robots do not attack artillery wagons.
Players were using remotely located artillery wagons in lakes to cheesily clear the map with no repercussions. Swarms of destroyer capsules would hover over the artillery but not target it. They would timeout and the player could then refill the wagon with ammo.
I've changed the entity_died_events file to events.lua since it now has on_entity_died, on_player_died and on_combat_robot_expired.
I have added the on_combat_robot_expired event so that when the robots timeout they explode, damaging nearby entities.
* Simple entity removal in Builders
Performance could be improved
* Removed rocks parameter
The increased radius caused simple-entity to work
* Added another way to remove units that should be more efficient
* Changed find_entities to use area instead of radius
* removed remove_units function
* changed function name from names to name
* added table.shallow_copy
* reworked 'remove_*' builders
* used remove_* builders for existing maps
* update .luacheckrc
* Added links to documentation for each public function
* Added links for new functions
