About this Mod
Instanced Dungeons
This mod is in active development. And while it's in a playable state and all known bugs have been fixed, the structures are all built by myself. And I would describe them as "programmer art" :D
Contributions/suggestions/critique are always welcome! You can reach me on GitHub or on Discord.
Instanced Dungeons are dungeon structures which exist separately for each player.
This means that each player has their own instance of this structure, allowing all players to explore the dungeon at their own time.
Players in a team can join teammates in their instances.
Instanced dungeons can be reset by the owner, which regenerates the structure to a new random layout, so it can be experienced again.
Accessing the dungeons
Instanced Dungeons comes with built-in data packs that add "dungeon entrance structures" to the overworld. They contain a block that allows teleporting the player to their dungeon instance (or to instances of team members).
Each "entrance" leads to the same dungeon instance. Upon leaving the instance players are teleported back to the coordinates where they entered the instance.
Technical information
Instanced Dungeons makes heavy use of blocks and features from the Script Blocks mod.
If you want to built your own entrance structure to the dungeons (either as a static structure for your server or to be generated in the world), you are very welcome to ask questions in the Discord.
