My second question:
I want to have a HideInventory.
In the inventory you can hide/show different groups (players, vips, yter, and admins).
But I don't know how I should make that.
I want to work with ArrayLists and Permissions(for the groups).
If you can explain that detailed to me, I would be happy
Thanks for your help!

(I am from Germany and have no very good Enlish skills. Sorry )

//Edit The Problem with the error is fixed!

 

@xX1yeahXx Please mark the thread as Solved.

Thread tools > Edit thread > Prefix > Solved

 

@timtower It is an inventory where you have some options to hide different groups of players. (You can't see them)

Spieler verstecken = Hide Player (German)
I hope you understand my plan.

@bwfcwalshy
Why solved?
I also have a second question with the hide system

 

@xX1yeahXx Sorry I didn't notice there were two questions.

If you want to show different groups you could store the players in that group by looping through the players and checking their permissions.
Then if you wanted to show everyone in that group in a GUI for example you could loop through the list and add a new ItemStack with the display name of there player name and add it to the GUI.
