About this Mod

Ever wanted to take lava out of a cauldron with a bucket using a dispenser? Well now you can!

demo

This server mod adds new behaviors to dispensers to provide the following functionality:

Dispense an empty bucket into a full cauldron and pick up the fluid from inside
Dispense a full bucket into an empty cauldron and place the fluid inside
The same above behaviors for water bottles (non-bucket, only water) and buckets of powder snow (non-fluid)

Any fluid that can be put in both a cauldron and a bucket should work!
