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" }
