Structures
A Structure is an artificial formation, often inspired by Original games/anime places, that generates randomly in your world. They play a very important role in the Pokemon experience.
Generations structures do not replace default structures or structures from any other mod, but may integrate them with Pokemon-related features and loot.
While Minecraft structures are seed-based most Generations structures are not, meaning that two worlds sharing the same seed will generate structures in different positions.
They are an important source of rare items, blocks and challenges, as structures are often house to one or more Pokeloots, a Spawner or a Shrine.
Simirarly to default structures, it is possible to disable their generation by turning off the "Generate structures" world creation option.
