Make someone invisible?

How can I make a player invisible?

 

.hidePlayer();

 

Actually its more like playeryouwanttohidefrom.hidePlayer(playertobehidden);

 

When a player logs out and back in, does it reset if he is hidden or not?
Is there anyway to show everyone after I have hidden some people?

 

use a for loop?

 

to show someone hidden as soon as they log in, I would think you need to setup a yml file to hold Data.

Like for example:
plugins/MyPluginData/Player.yml

Code:

Players:
  XDemonic:
      Flags: 0
  Caveman:
      Flags: 1

Where Flags: 1 Would make the player invisible when he logs in. Though you would need to code for that check.

 

How would you un-vanish?

 

Bit old...

.showPlayer();

 

Lol ok.
