Config:
spoutcraft.enable
Lets you enable the special spoutcraft features. These do not require spoutcraft but will just be added for players with it

Permission: vanish.spout.status
If spoutcraft features are enabled, users with this permission have a little box that tells them when they're invisible

Skins, cloaks, titles!
Define custom skins cloaks and titles in spoutcraft.yml (autogenerated with examples on first load)
If you define a skin called 'admin' then give users the permission vanish.spout.skin.admin
If you define a title called 'vanished' then give users the permission vanish.spout.title.vanished

This way you can give people group-based or individual-based titles skins and cloaks.

Title formatting:
&&x for a color such as &&b is aqua
%n is the player's name
%r is a newline

spout build #567

No perm plugin

A command such as "/?v(anish(ed))" or "/isv(anish(ed))" would be infinitely useful, as I occasionally catch myself out with regards to whether or not I am invisible.

I'm not sure if it's possible, but correct me if I am wrong.
I want to make a hierarchy with my groups as to who can see others status updates, etc.

For example, my 3 groups:

Mod
vanish.statusupdates.admin: false
vanish.statusupdates.op: false
vanish.see.admin: false
vanish.see.op: false

Admin
vanish.statusupdates.mod: true
vanish.statusupdates.op: false
vanish.see.mod: true
vanish.see.op: false

Op - can see everything

This way, my admins can see when my mods vanish, but can not see ops.
Get it?

Thanks for reading.

"wont hide me on the dynmap"

Is it possible to recreate the ACTUAL join and leave messages so that other plugins can hook them like normal?

things like random join messages and per user colorings give it away when you are using vanish.

Hi,

I want to use VanishNoPacket for visitor.

I want they can't do anything when they join my server.

This is my config.yml (permissionBukkit 1.2)

users:
GrenadeLaPome:
permissions:
groups:
- default
groups:
default:
permissions:
permissions.build: false <- can't build
vanish.nochat: true <- can't speak
vanish.nofollow: true <- can't be killed/follow by creeper, zombie, ...
vanish.nointeract: true <- can't use door, button, ...
vanish.nopickup: true <- can't pick item on the ground
vanish.preventincomingdamage: true <- can't die
vanish.preventoutgoingdamage: true <- can't kill
vanish.see: true <- can see other visitor

help me :(

I've removed the invalid UTF-8 character from your sources (the 0xA7 sign), added Permissions support (by default; otherwise uses Bukkit permissions. Extensible). Also now gives a more verbose notification when update failed.

The source in the repository reports itself as being 0.0.0.1 versions out of date, BTW. Might want to fix that?

I've no idea how to attach the patch so I'll leave it here

I cannot open doors or access chests/furnaces/dispensers while vanished. Is this intentional? If so, please add an option to disable it.

I first noticed this issue a few days ago so I don't know how long it's been there.
I'm using VanishNoPacket 1.8.8, Dynmap 0.28 and CB b1597, staff vanishes automatically on join (not on purpose, PEX doesn't like negative permissions) and are invisible on dynmap even when I disable dynmap hooking in the config file and they're visible ingame.
There are no errors in the console.

If i do /vanish and get the message saying I'm invisible in the lower left, the second another admin does /vanish mine goes away, basically only the last person to vanish gets the spout gui message.

admins always join the server as invisible. i dont see an option to fix this in the config.

Hi!

We have a problem with Dynmap. When I toggle on invisibility, dynmap hides my player. But when I'm visible again, dynmap keeps me hidden.

Also, when I disconnect, the server doesn't show "agubelu has disconnected", regardless I'm visible or not.

config.yml:

fakeannounce:
automaticforsilentjoin: false
join: '%p joined the game.'
quit: '%p left the game.'
hooks:
essentials: true
dynmap: true
JSONAPI: false
enableColoration: false
spoutcraft:
enable: false
updates:
check: false
permtest:
enable: false

Vanish 1.8.3
Dynmap 0.25.1
CB 1337

We are seeing some ghosts of invisible players being left behind if they log out and in or teleport while invisible. Also, teleporting while invisible drops you from a huge height. Logging back in while invisible replaces you at the highest point above you.

When I login vanished and silentjoin Spout Essentials still shows my name as a acheivement notification.

If a player's permission set changes, update the player's permissions.

eg. If a player is no longer allowed to vanish, unvanish the player.

Op group, which only contains a "*" node, as well as op=true, for myself. When I run /vanish toggle it tells me "you cant toggle anything" And besides not liking the tone that your plugin is talking to me, I am wondering what is going on?

I would like to vanish and be able to auto-follow a suspicious player as he moves around. After I issue the command, I can sit back and watch as my player moves to match another player's movement.

Commands:
/vanish follow
/vanish unfollow

We would need a permission:

• vanish.follow

And config.yml settings:

if true, then if no player is specified, then follow the nearest player; if false, then a player must be specified on the command line

follow-nearest-player: true

default following distance if not specified

follow-distance: 10

as long as our distance to the followed player is +/- the threshold, just stand still to prevent excessive relocation

follow-threshold: 3

if follower specifies a distance smaller than this minimum, use this instead

minimum-follow-distance 3

if true, then rotate the follower to face the followed player (adjust the facing direction every couple of seconds to face the followed player as he moves to the side)

always-face-followed-player: true

announce following to others who have the follow permission

announce-to-other-followers: true

Note:

• set x,y,z to a safe place so you don't end up in a tree or a hill
• confirmation announcement says " is now following "
• confirmation announcement says " is no longer following "

I'd be happy to be an alpha tester of this for you.

I gave myself the vanish.* node.
Every time I join, I re-toggle the vanish toggle-able settings.
If i restart the server. All my setting are lost. :'(
Please add a save.

First off, I'd like to say that this is an amazing plugin. However, the only flaw that I can think of is the fact that when a player uses /list in mChatSuite, it will list all the vanished players as well as the non-vanished ones. Do you think that you could add support for this plugin and hide vanished users from this list?

Using CB#1566, vanish 1.8.5

When you are vanished, the player count still shows the true number of players on the server before they join (on the server listing).

config.yml - http://pastebin.com/GpL5GSZu

Whenever I use the vanish command other players are disconnected from the server. Since the plugin isn't officially supporting the current dev bukkit build this will give you time to tackle it until the recommended build comes out.

I'm moving us from essentials to CmdBook and I was wondering it it would be possible for vanish to keep us admins/mods from being spotted by it. Namely cmdbook's login notifications and it's /list-who.

It would greatly assist me in keeping my sanity.

Spout-based notification of vanished status.

I got this message in my server log, said I should report it, so I did:

I use PEX 1.17, Spout 644, Dynmap 0.27 and CraftBukkit 1597.

If a player attempts to place a block where an invisible player is, they will be unable to. I don't know if it's possible to solve this but it would be awesome if you could.

"dynmap hide name" and "dynmap show name"

Both can be used to reveal the presence of a vanished player

In our server, real join/quit messages have color codes like so: &cagubelu &ehas joined.

I tried putting color codes in the fakejoin/quit mesage for them to be like the real ones, but they suffer a breakdown.

Could be possible to include this feature?

Thanks.

For some reason, the spoutcraft features dont seem to be working for me...

Yes, I do have spoutcraft enabled inside the config.

Only the individual toggle permissions seem to be working.
RB: 1.0.1 R1
Vanish: 1.8.6
Permissions: Pex 1.17

Possibly in a separate plugin, for visibility-dependent tasks

Sorry that I can't add much info on this one other than the stack trace. Saw it in console, but wasn't in game nor know who tried a command or whatnot.

Well, hope it helps, yeah? ^^;

I think that there should be a toggle-able feature where you can access a chest when vanished without it making the sounds and showing the opening and closing animations.

Please add a feature so when you are hidden your name isn't shown in the player list so if you use the /vanish fakequit command, it would be 100% realistic.

I don't know if this is possible or not, but if it is, please implement it into Vanish! I would be glad to test it :)
