Spawn Detail Presets

Preface

The JSONs in the spawn_detail_presets folder create the presets that are used in Pokémon spawn files. Presets are simply a collection of conditions, anticonditions, and contexts that are bundled up into a new preset named after the JSON file name! They are a great way to make familiar scenes into a simple tag you can use when making spawns.

Preset Breakdown

You can make a preset as simple or complex as you like. The complexity of it depends on your understanding of spawn conditions, biomes, and your creativity. Almost all presets include one major condition. This condition is a list of blocks that the Pokémon can spawn on.

Here is a breakdown of the ruined_structure preset. Its conditions are very similar to being in a Stronghold. Hover over the underlined text to see more information.

{
   "condition": {
       "canSeeSky": false,
       "neededBaseBlocks": [
           "minecraft:cracked_stone_bricks",
           "minecraft:mossy_stone_bricks",
           "minecraft:chiseled_stone_bricks",
           "minecraft:mossy_cobblestone",
           "minecraft:iron_bars"
       ],
       "biomes": [
           "#cobblemon:is_overworld"
       ]
   },
   "anticondition": {
       "biomes": [
           "#cobblemon:is_abyss"
       ]
   }
}
