Better spawn protection improves on the vanilla spawn protection by making clients aware of spawn protection
This can be used clientside only, BUT it will default to 16 so if the server has a customised spawn protection size this mod will not work as intended, it is recommended that this be installed on the server as well so it can tell the client the true size.
Trying to break a block will show red or the customised colour, it also stops the block from starting to break so no sounds will be played and no block break animation either.
