NameLayer

The overview screen in the in-game NameLayer interface, as shown by /nl. Each chestplate is a group, and the material is the player's rank in that group.

NameLayer is a common plugin on civ servers which allows for the creation of shared groups. Any player can create a group, and there is no limit on the number of groups a player can be a member of. Each group has a tiered rank structure, with players having varying level of permissions inside a particular group.

Groups interact closely with Citadel, which allows reinforcing a block to a specific group. The group a block is reinforced to informs several other plugins. For instance, Citadel protections can be bypassed by players on their group, snitches and bastions will not affect players on their group, and item exchanges can be locked to a specific group. Groups can also be used to send chat messages visible only to players on that group.

First introduced in Civcraft, NameLayer has been included in every mainline civ server since.

Mechanics

Rank

Groups come with a set of ranks. A widely used set is primary owner > owner > admin > mod > member, but this is not universal across civ servers. Players cannot create, rename, or move the ranks themselves, but they can assign players to different ranks.

Each group can have only one primary owner, though primary ownership can be transferred by the current primary owner. Other ranks have no limit on the number of players in them.

Permissions

Each rank comes with a default set of permissions. The permissions each rank grants can be modified for a particular group.

Base Namelayer Permissions

LIST_PERMS	Allows seeing how the permissions are set up for the group

Other plugins can add permissions to groups, which are not a part of the base NameLayer plugin. These permissions act the same as the base permissions in that they can be modified on a per-group basis. The permissions provided by the most common plugins are listed below. Note that there may be permissions in this table which are not present on a civ server, and vice versa, depending on which plugins a particular server includes.

Interface

The group screen in the /nl interface. Each chestplate is a member of the group, with rank shown by the chestplate's material. Various group management and display options are shown in the top and bottom rows respectively.

While groups can be managed entirely via commands, there is also an in-game interface which can be brought up with the /nl command.

In this interface, the material of a chestplate correspond to a player's rank in a group. Leather is member, gold is mod, iron is admin, and diamond is owner or primary owner. An enchanted chestplate denotes that group as the player's default group.

The first /nl screen is the overview screen, which shows all groups the player is a member of. Chestplate material denotes the player's rank in that group. Clicking on a chestplate will bring up the group screen.

The group screen shows all members of that group and their respective ranks.

Unique Usernames

Although Minecraft allows updating your account name, NameLayer mechanics rely on a player's username being unique. NameLayer will use whatever username you first log in with. Changing your Minecraft account username will not change it on your NameLayer groups.

If a player logs in with a username which is already in use in a NameLayer group on the server, that player's displayed name will have a "1" appended to it.
