Version 4.X.X

For older versions of the mod, check the wiki.

This Mod adds, that access to dimensions can be granted or locked.
If a dimension is locked, you can stand in the portal to this dimension, but don't change to this dimension.
If a dimension is granted, you can stand in the portal to this dimension and change to this dimension.
Since Minecraft 1.19.1 the Mod is needed on the server and client side.
For 1.19 and before, the Mod is only needed on the server side, but can also be used on the client side.


You need a server to play with friends? You don't know how to set up one? Just rent an already configured server!

Granting / Locking

There is a general flag, a whitelist and a blacklist, to manage which players have access to a dimension.

Flag

For every dimension can be set, if the dimension access is granted or locked.
If a player is not on the white- or blacklist for the dimension, this flag is used to define, if the player can teleport to the dimension or not.
For non player entities, this flag is used to define, if they can teleport to the dimension or not.

Whitelist

The whitelist is only active, if the dimension access is locked.
Players on the whitelist, can teleport to the dimension, even if the dimension access is locked.
If the dimension access is locked and the whitelist is active, only players and no other entities can teleport to the dimension.

Blacklist

The blacklist is only active, if the dimension access is granted.
Players on the blacklist, cannot teleport to the dimension, even if the dimension access is granted.

Server Config

The config file can be found in the "serverconfig" folder in the "world" folder and is named "dimension_access_manager-server.toml". The name of the world folder is set for servers in the "server.properties" file and for clients it is the name of the world/save game in the world list, and it can be found in the "saves" folder in the ".minecraft" folder.

  • default_dimension_access_type
    Defines if new dimensions are GRANTED or LOCKED by default
    Default = "GRANTED"
    The access type for a dimension is set, if the dimension is generated for the first time.
    I.E: This value should set before pre-generating the dimensions.
  • dimension_command_permission_level
    Defines which permission level is required to run the /dimension command
    Default = 3
    Available values = 0, 1, 2, 3, 4
    By default, only operators, that can change the whitelist, can change the dimension permissions.
    If the commands shall be executed by a command block of i.e. HQM the permission level has to be 2 or less.
    More details about minecraft permission levels, you can find here: https://minecraft.fandom.com/wiki/Permission_level
