Improved Performance. Fixed an issue where mobs stop before continuing to run again.

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" }

• Now, mobs may fear an entity/mob.

For example, if you want the mobs in your group to fear the wolf: [["Fear Groups".fear_groups.feared_entities]] id = "minecraft:wolf"

• Some fears are too overwhelming, making them run away without targeting you. To do that, add "fear_override = true" into the entry.

For example, if you want them to fear the lit soul campfire so much that they don't attack you: [["Fear Groups".fear_groups.feared_blocks]] id = "minecraft:soul_campfire" fear_override = true

		["Fear Groups".fear_groups.feared_blocks.states]
			lit = "true"

v2.0.3 Change log:

• Mob will only run from a feared block or item if they have vision of it.
• Fix a bug where the end crystal does not cause fear.
• Fix pathfinding.

• Support Minecraft tag, for example:

Items

{ id = "#minecraft:axes" } { id = "#minecraft:swords" }

Blocks

{ id = "#minecraft:campfires", states = { lit = "true" } } { id = "minecraft:lava" }

v2.0.1

2.0.1 (2025-10-08)

• Add per-group light-level avoidance:
  • light_fear.enabled: default false (off by default)
  • light_fear.mode: ABOVE (avoid bright) or BELOW (avoid dark)
  • light_fear.threshold: 0..15 (default 11)
  • light_fear.layer: COMBINED (default), BLOCK, or SKY
  • light_fear.hysteresis: margin to prevent jitter (default 1)
• New AI goal LightFearGoal that moves mobs toward positions with acceptable light.
• Config: lightCheckCooldownTicks to control light evaluation interval (default 20 ticks).
• Version bump to 2.0.1.
• Fix mods.toml dependency keys to dependencies.firefearmod.

Notes:

• Light fear is disabled by default for all groups. Enable it per-group in config/firefearmod-common.toml.
• Combined brightness is used by default to work both indoors and outdoors.
