Bossbar Lib

What is it?

Bossbar lib is a library that provides entity specific bossbar functions. It is highly reccomended that you use a datapack to use this however commandblocks will work fine.

Functionality:

Upon creating a bossbar you will be able to display the bossbar with function bb_lib:display_bar. If the entity is a player, that entity will see the bossbar for themselves, if not, you will need to add the bb_lib.display_bar tag to the entity to display it to all nearby entites.

How to use:

After installing the datapack and reloading you will be able to create a bossbar. To do this run the function bb_lib:create_bossbar command to create a bossbar for yourself. To craete it for other entities you will need to execute as them. To display your bossbar, in a repeating commandblock you need to run execute as @a run function bb_lib:display_bar. If you wish to change your bossbar you will need 2 commands at a minimum: in a repeating commandblock: execute as @a run function eb:update_bar and then to change the values you can use any of these commands:
function bb_lib:set_value {property:<PROPERTY NAME>, value:>VALUE TO SET PROPERTY>}
