Various commands can expose vanished players

See original GitHub issue

Description

Describe the bug

Commands such as coop, trust or invite can expose vanished players.

Steps to reproduce the behavior

Install BentoBox, BSkyBlock and a vanish plugin (e.g. ProtocolVanish).
Connect the first account as a regular player.
Create an island.
Connect the second account as an administrator and put it in vanish.
As the regular player, execute /is team invite <administrator>. => It will send the invite, thus letting the regular player know the administrator is online.

Screenshots and videos

None.

Expected behavior

Players “hidden” by vanish plugins should not be exposed through the commands. They should be deemed “offline” by the plugin. The same should go for tab-completion (and it has already been reported and fixed a while ago on ASB).

As far as I know, we can check if the player’s vanished by using Player#canSee().

I tested this on build #1860 and it works fine, thanks. I didn’t find any other possibilities to expose vanished players - in my opinion the issue could be closed now.

Created PR to support making vanished players appearing offline (Note this PR should only be considered as a temporary fix for users & to be replaced at a later date with a more in-depth system.

EDIT: This has since been adjusted to use the correct methods & will need approval for merge
