About this project

What does DimensionAccess add?

DimensionAccess is a lightweight server-side Fabric mod that gives server operators full control over which dimensions players can access.

Features

Disable any dimension - prevent players from entering specific dimensions such as the Nether or the End
True cancellation - the teleport is blocked before it happens: no achievement, no chunk loading, no side effects
Live reload - update the config without restarting the server
Auto-complete - commands suggest valid dimension identifiers automatically

Commands

All commands require OP level 2.

Command	Description
`/dimension disable "<id>"`	Block a dimension (e.g. `"minecraft:the_nether"`)
`/dimension enable "<id>"`	Re-allow a previously blocked dimension
`/dimension reload`	Reload the config from disk

Configuration

Blocked dimensions are saved in config/dimension_access.json and persist across restarts.

{
  "disabled_dimensions": [
    "minecraft:the_nether",
    "minecraft:the_end"
  ]
}
