Set player transparent (like with team invisibility)

As the title says, is this possible?

I know when using the scoreboard system, you can set so that team mates can see each other when invisible, which works as them being semi transparent.

Can I set a player to this state, without having to use the scoreboard system?

 

I think the scoreboard system is all you can do, unless bukkit somehow has a feature to set the player's alpha (transparency).

 

yea, but I kinda wanted to avoid the scoreboard, and seeing as it's a feature I was hoping it could be possible.

 

playerA.hidePlayer(playerB)
Where playerB is hidden from playerA.

EDIT: Oh, I missed the semi-transparent bit. Yeah, I don't believe there's a way to do this without hooking NMS.

 

I know. but what I wanted was them to be semi transparent, not entirely hidden.

 

I edited my post just after you posted this.

But essentially all it does is apply an infinite invisibly potion to them and add them to a scoreboard team.

 

What 'bout packets

 

Unfortunately, most of the scoreboard system is client side, so it can't be done. Blame Dinnerbone.
