About this Mod

Structures for Radical Cobblemon trainers.

Currently in beta, bugs are to be expected. It is recommended you make regular backups of your world.

Tired of walking around and waiting for gym leaders to spawn?
This datapack adds naturally generating, survival friendly gym structures that house the 8 kanto gym leaders, elite 4 and champion featured in the radical cobblemon trainers mod, with more structures soon to come.

You need command blocks enabled on your server for this datapack to function.

Currently there are the 8 kanto gyms & kanto league:

  • Pewter Gym (Brock)
  • Cerulean Gym (Misty)
  • Vermilion Gym (Lt. Surge)
  • Celadon Gym (Erika)
  • Fuchsia Gym (Koga)
  • Saffron Gym (Sabrina)
  • Cinnabar Gym (Blaine) [Nether]
  • Blackthorn Gym (Claire) [End]
  • League Building (Elite 4 & Champion) [End]

However I plan to add more structures such as:

  • Battle tower
  • Team rocket hideout
  • A structure for rival encounters
  • A post-game structure for Trainer Red

It is HIGHLY recommended to use another mod to help you locate these structures such as Explorer's Compass.

I also recommend using the Radical Cobblemon Trainer Textures Plus resource pack to give accurate skins to your trainers.

(I am currently not intending to add structures for the BDSP series)

Dependencies:

Huge thanks to the creators of Radical Trainers Structures for doing this first and their work being the base for this project & The Cobbleverse modpack for heavy inspiration.
