Mod description
Very fast item collectors that collect items that would be dropped in the world, before they even become entities

Why would you like the mod added?
Good for performance as it stops items spawning at all, and the other item collector I could find (ender hopper) was much slower

Devil's advocate: What's the benefit of these over the options we already have?

To me, the speed of the pickup is a non-issue. What causes lag is lots of entities. That only happens in a farm if the player has not designed for overflow management/auto shut off.

This won't solve those issues. This can pluck items out of the air instantly for all it matters, if there's nowhere for the items to go, that's it.

For reference, we have quite a few options for this:

1. Ender Hopper from Dark Utils
2. Smart Chest from PNC
3. Occultism demons
4. Alex's Mobs Crows
5. Nature's Aura has a hopper whose name eludes me right now
6. Ars Nouveau's spell turrets and Carbuncles
7. Botania Hopperhocks
8. Pedestals
9. Create has various ways of picking up items from the world

And probably more I'm missing right now.

To me they're a better ender hopper from dark utils, we could even disable it if we add this. All the other options don't really well work in a compact automation setup imo besides maybe the smart chest from PNC and pedestals. They're just a clean solution to that imo. Could be gated to be a bit more expensive like flux networks

I think this would just be duplicate content tbh :)
