@WizardlyBump17 , useless. All this is is just code, you are not explaining anything. No one can learn anything from this

 

Well it is a Util, not a tutorial. If you understand how to code it's pretty self explanatory. The second chunk of code is them giving an example of how the code can be used. The top chunk of code is the actual utility, to send an action bar message to a player, and to broadcast an action bar message.
