About this Mod

Description:

This mod allows the creation of netherportals ONLY within the bounding box of certain structures F.E.: Ruined Nether portals.
This restriction allows for more incentive to explore and more storytelling options in RPG modpacks, Datapacks, and Adventure maps.
You can add any number of Structures to the list within your config files of allowed structures, even modded ones.

Tips:

  • The config file is named structureportals-common.toml , deleting this will reset it to default configs.
  • You need to restart your game for configuration changes to apply.
  • To look up the exact structure ID's use the /locate structure command the autocomplete will list you the ID's.
  • Minecraft vanilla structures can be put into the list like so: "structure_id"
  • Modded structures need a modid like so: "modid:structure_id"
  • Return portals still generate everywhere but they cannot be re-lit after they be destroyed

Known Issues:

  • Terrafirmacraft removes the bounding boxes of every structure (even with vanilla generation) and thus isn't compatible
