A simple mod to block the access to dimensions!
About this Mod
What is this mod?
Dimension Blocker is a server-side mod that adds new commands to block access to dimensions on your server!
This mod only block access through portals and teleportation but not with /execute, so admins have still a way to teleport to restricted dimensions.
What new commands?
Here is the list :
- /blockdimension [dimension_name] : Block the dimension provided.
- /unblockdimension [dimension_name] : Unblock the dimension provided.
- /languagedimension [language] : Change the language used by the mod for the player.
- /getdimensionpermission [dimension_name] : Get the permission name linked to the dimension (you can click on it to copy to the clipboard), add it to a group or a player with your permissions mod to allow the access in a specific dimension.
What is the translations system?
A config file "dimensionblocker_translations.json" is automatically generated on server start, you can add translations as below that your players can use with the /languagedimension command (here i added a french translation):
{
"en": {
"dimension_cancel": "You can\u0027t teleport to this dimension.",
"blockdimension_success": "Dimension is now blocked!",
"blockdimension_failure": "Dimension is already blocked.",
"unblockdimension_success": "Dimension is no longer blocked!",
"unblockdimension_failure": "Dimension is not blocked.",
"dimensionlanguage_success": "DIMENSION language changed!",
"dimensionlanguage_failure": "Error : The language provided is invalid.",
"version": "1"
},
