About this Mod
No Swimming is a mod that removes the player's ability to swim.
In order for the player to be able to swim again, they need to use the Swimming enchantment on their boots.
This enchantment has 2 levels:
The first level allows the player to float on the surface of the water, but they will not be able to swim. If they sink, they will not be able to come to the surface.
The second level will allow the player to swim completely.
Although it may seem like a mod that is quite annoying at the beginning of the game, the mod has a trick that will make it not so annoying.
If you have not yet been able to enchant the boots and by mistake you fall into the water at a shallow depth, you have a way to save your life.
If you are placing slabs or stairs, you will be able to climb them without any problem.
So you should always carry a few slabs or stairs in your inventory until you manage to enchant the boots of your armor.
