About the mod

This mod allows to set items that can only be placed in the main hand (the selected inventory slot in the hotbar) or the offhand, outside those slots, the item will be dropped. I made it to nerf water and lava buckets, but can be used for any item, just add the item in the config list. I don't like the fact that a water bucket is considered a "meta", it works for too many things. So this mod allows me to make so that it is more annoying to carry a water bucket arround. By default, water and lava buckets are added in the list.

In the config, what hands are allowed to hold the items can choosen, which can be the main hand, the offhand, or both.
A message is displayed when the item is dropped, this message can be disabled in the config.
A message can be added when the item is picked up in the config file. By default it is disabled.
