WHAT IS INTEGRATED DUNGEONS AND STRUCTURES?

Integrated Dungeons and Structures (aka IDAS) is a mod that adds heavily detailed structures using blocks and mobs from Quark, Alex’s Mobs, and Create, with optional integrated with many other mods. I got sick of installing structure mods into a pack and roaming the world, only to find vanilla items and nothing of difficulty anywhere. I love detailed builds and Create machines, so I decided to make a mod that adds exactly what I’ve been missing. Beautiful and challenging dungeons and structures packed with lore that are fully integrated into multiple core forge mods.

If you’re new to this mod I highly recommend locating a Labyrinth, Tinker’s Workshop, Ancient Mines or a Pillager Fortress and playing through it. Those took by FAR the most time to build and I believe they are genuinely very fun and rewarding. Good luck!

  • Integrated Minecraft, the official modpack for the Integrated Structures series
  • Integrated Stronghold
  • Integrated Villages

Configuration and optional Integration:

For 1.16

Edit the config files IDAS automatically detects if Ice and Fire is installed and will change some structures loot and mobs

For 1.18 and above To enable BOP integration, download this datapack. To enable Alex's Mobs integrated, download this datapack

To configure anything else, download this datapack

  • To change spawn rates change the spacing and separation in the structures sets. Spacing is the Average distance between two neighboring generation attempts. Value between 0 and 4096

Separation is the Minimum distance in chunks between two neighboring attempts. Value between 0 and 4096. Can't be bigger than spacing

  • To edit biomes, edit the biome files in tags/worldgen/biome/has structure
  • To disable structures, remove all the biomes for their tag list or raise the separation and spacing to crazy high numbers
  • To improve compatibility with other structure mods, add structures to the “structure set to avoid” list in each of the worldgen/configured_structure_feature files

Note: When using the global datapacks mod, if you’re using both the BOP and config data packs, you have to manually make sure that the data pack for bop integration is above the config data pack.

Features and Planned features:

Over 50 unique heavily detailed structures in the Overworld and Nether dimensions including:

  • 20 unique small and detailed world building structures such as campsites, markets, animal dens, and more
  • 7 Endgame level dungeons ranging from expansive dwarven mines to the desert Labyrinth to the Pillager Fortress
  • Create themed Dungeons with spinning death traps such as the Tinker's Workshop
  • 15 unique houses and inns for weary travelers

  • Sunken pirate ships
