Development Assistance [Bug?] how to fully remove xp bar

Hey guys,

I was recently programming and made a mistake, the results gave me a pretty sweet bug and i thought id share it with you all

NOTE: This does not generate errors to the console!

NOTE: I also havnt tested this with 1.7.x! only 1.8

All you need to do is,
player.setLevel(-100);
and that will remove the whole exp bar leaving it looking like this: http://gyazo.com/2ee424db63c89947f9282628bde1f31e

 

@TeddyDev Wrong place in the forums.
What would happen if a player was to get more xp?

 

@TeddyDev @DJSkepter Not much of a bug, but i'm assuming as a player gains xp it will re appear. Also, this should be moved to resources section.

 

@ProMCKingz
This isnt in the wrong forum because its about bukkit development.

@DJSkepter
Players would eventially get there xp bar back when -100 levels have been collected.
if you wanted to remove the bar for a very long time, use -999999 instead
