Customizing Entity Fishing

Spectrum's Fishing Rods (additionally to being able fish in more than just water) use a mechanism called Entity Fishing. It does exactly what is written on the tin: when fishing in a liquid, there is a chance to lure in an entity!

You can specify which entities are fished where by placing json files in the directory <data_pack_or_mod_name>/entity_fishing/.

Properties:

• (FluidPredicate) fluid: The fluid that can contain fishable entities (like via fluid id, or fluid tag)
• (BiomePredicate) biome: The biomes these entities can be fished in
• (LightPredicate) light: The block and sky light of where these entities can be fished
• (DimensionPredicate) dimension: The dimensions these entities can be fished in
• (MoonPhasePredicate) moon_phase: The moon phase these entities can be fished in
• (TimeOfDayPredicate) time_of_day: The time of day that these entities can be fished
• (WeatherPredicate) weather: The weather these entities can be fished in
• (CommandPredicate) command: An arbitrary command to test against
• (float) chance: The base chance to fish an entity instead of the usual loot. This value is multiplied with the "Big Catch" enchantment's level, should the fishing rod be enchanted
• {} entries: A weighted list of entity entries that can be fished
  • (Identifier) entity: The entity that will be fished up
  • (int) weight: The relative likelihood that this entry is selected
  • (String) nbt: A standard NBT string that will applied to the entity
  • (JsonNBT) nbt: An NBT compound using Spectrum's custom JsonNBT format, which will be applied to the entity
