No Mob Boats

Summary:

A mod that allows for preventing animals and monsters from entering boats and has config options to choose how many and what mobs can sit in them

Not only is it for bringing back old boat behaviour, it also works for modpack balancing purposes, such as preventing enderman cheesing with boats!

Config:

The mod comes with a SERVER config, which doesn't generate in the config folder, but instead, in the world folder. You can always move it to defaultconfigs to automatically enable it for all new worlds

mobBoats:

false = only allow players, nothing else
true = allow mobs, can be limited by enabling tagOnly option

tagOnly:

The mod has an entity_type tag that defines which mobs will enter boats (only when "tagOnly" is enabled and you must have "mobBoats" enabled too!), unfortunately, this doesn't allow adding new mobs that weren't previously allowed in boats, only for limiting those that normally were

seatAmount:

Allows to choose how many mobs can enter a boat.
Yes, you can set it to 0 just because

Seems to work server-side, clients aren't required to have the mod :)

Doesn't dismount already mounted mobs
