Fast way to find a spawner given an entire surface/force

[Reika]

Any spawner will do. In all likellihood this would be similar to the internal code used by the artillery weaponry, which also find spawners - presumably without iterating across all entities on a surface.

art towers have a position and a radius so the area is clear - how you want to do that without position and radius though?

This prospective function could easily request that - though in my case, the radius would be infinity.

My point is that the artillery does not lag like a massive entity scan would, so they must use some internal game engine lookup that I would like exposed in the Scripting API.

The artillery scans 1 chunk per tick, slowly circling out from its own position, and searched the chunk for any targets

I would say the fastest way is to just let the C++ do it, surface.find_entities_filtered{}

That is not useful to me, because I need to find a spawner specifically, not just any enemy (which in all likelihood is a unit).

Then there's nothing that will do that. The closest is what the artillery does but it iterates chunks of entities at a time until it finds an entity in that chunk that's a spawner or turret.
