In the Pixelmon mod, specific block types prevent Pokmon from naturally appearing on them. These restrictions are programmed into the game to manage spawn locations and prevent unintended occurrences. For example, Pokmon will typically not spawn on man-made structures such as player-placed blocks, paths, or transparent blocks like glass or slabs in many scenarios. This helps maintain a balanced and predictable ecosystem within the game world.
Understanding these spawning limitations is vital for players looking to strategically construct their bases or manipulate Pokmon habitats. Knowledge of which blocks are non-spawnable can assist in managing the areas where Pokmon appear, preventing them from spawning in unwanted locations, such as inside buildings or designated safe zones. This knowledge also allows for optimized breeding environments, where desirable Pokmon species can be encouraged to spawn through careful manipulation of the surrounding block types.
