How it works · RoodyCompressor · Documentation

Every second (configurable), and instantly after a pick-up or closing a chest, the inventory of each player is checked.
The recipes used are those of every compressor item the player carries turned on. A higher tier can inherit a lower one, so the top tier does everything.
Recipes repeat until nothing changes, so a full chain climbs all the way in one go.
It never runs while an inventory is open or an item is on the cursor, and it pauses after trading, so shops and villagers are safe. If an output does not fit, it only does what fits — items are never dropped.
Only plain items (on by default) means renamed or enchanted items of the same material are never touched.
