Solved Use Bossbar in 1.8

Is there a way right now to use the Bossbar correctly in 1.8? (Spigot)
Because in the 1.8 Client if you look away from the dragon/wither the health bar disappears after some time.
(I previously spawned a dragon under Bedrock but if you look up it doesn't work)
I tryed to spawn a dragon/wither 100 blocks in the direction the player is looking which works fine but you can see the dragon/wither and I couldn't make it invisible (don't know how).

 

@Timbals There isn't really a good way to do this, but you can make withers semi invisible (particles are shown). There is an NMS method to do so.

 

@Skionz which NMS method? And if you only see particles and i spawn the wither 100 blocks away from the player aren't the particles not rendered?

 

@Timbals Good point, but you can't see the bar unless the wither is closer. Here is the method

@Skionz Thanks it worked
btw if you spawn the wither at

Code:

player.getLocation().add(player.getLocation().getDirection().multiply(50))

you can't see particeles
