event = {entity = "assembler", recipe = "recipe" }

I want this for assemblers, but I might be able to see some use for players too.

We specifically don't have such an event because it would be a massive drain on game performance.

Don't we already have this for players?

Yes, because the player count is not in the 10s of thousands and has a fixed crafting speed.

Indeed, I was just pointing that event out because it seemed the OP wasn't aware of it.

Sorry for necroing an old thread, but would it be possible to have the recipe and/or crafting machine's prototype opt in to an event? So any performance problems can be minimised?

+1

Mods that want to do that will find a way and it will cost more performance that such an event (and might have restrictions with mod compatibility). For example using rocket silos or on-tick events with products_finished and/or crafting_progress.

This can be very restrictive, such that is has to be enabled per-prototype or even per-entity (similar to register_on_object_destroyed)

Having this built-in is also the only way to make this work with ultra-fast recipes that do complete more than once per tick (performance-wise this should still be fine if there aren't many of those entities).

I'm working on a script handler for such an event but it's not cheap to run. I'll be adding it to the following mod when it's done.
