Fear of Anything

Big update v3.0.0

New features:
+ INTERGENERATIONAL_TRAUMA_ENABLED
Default: false

This new feature unlocks a stage-based fear system where later stages can be conditional.
For example, a cow will fear fire-based blocks as stage 0. After being hit by a player,
that cow and any nearby cows will fear the player, which becomes the stage 1 fear.
A mob can belong to many trauma groups, and each group has multiple stages. The maximum
stage per group is capped by this config value:
MAX_TRAUMA_STAGES_PER_GROUP, default 3.

+ New fear override modes for the datapack system:
              visibility_mode: "ALWAYS"

When this option is included in the datapack, for example:
{ "type": "entity", "id": "minecraft:ocelot", "fear_override": true, "visibility_mode": "ALWAYS" }

The mob will fear the ocelot whenever it sees it, and with "fear_override": true it will not aggro
against that ocelot. If the "visibility_mode": "ALWAYS" is removed, the mob will only fear if both
the mob and the ocelot can see each other (mutual line of sight).

+ And finally, natural and forced breeding systems:

Using datapacks, you can customize which mobs will breed and under what conditions. For example:
if 2 skeletons are within an 8-block radius and one is holding a bone, they can breed. Since there
is no baby skeleton in vanilla, an adult skeleton will be born.

Example rule:

{
  "enabled": true,
  "mob": "minecraft:skeleton",
  "child": "minecraft:skeleton",
  "partner_radius": 8.0,
  "cooldown_ticks": 3000,
  "max_nearby_children": 8,
  "consume_item": true,
  "require_held_item": "minecraft:bone"
}
