Entity that deploys units on map

[Helveg]

Hi!

I'm interested to know if there's a way to let a building deploy units. Perhaps a modified roboport that deploys a modified flying robot? Or an assembly machine that destroys the item it produces and instead creates a unit on your force? I couldn't find an event in the API that triggers when something like an assembly machine / furnace completes a production cycle and checking the progression every tick seems like too much overhead. Any ideas? What's viable?

Solved it! I can create my own unit-spawner entity! If anyone is interested look in enemies.lua for the biter-spawner entity as an example.
