Ducky Quack Pack 2.0
A cross-loader Minecraft mod that adds ducks with a fully rewritten flocking AI, natural spawns, custom sounds, taming, and craftable items. Supports Fabric and NeoForge. Powered by GeckoLib 5.4.5.
Find us on CurseForge or Modrinth.
What's New in 2.0
2.0 is a ground-up rewrite of the duck AI. The old goal-based system has been replaced with a single hierarchical state machine (DuckBrainGoal) that owns all locomotion decisions. This eliminates the race conditions and formation bugs that plagued 1.x.
- Flocking AI rewrite — Ducks self-organise into leader/follower chains. The leader duck is marked with a particle crown. Followers track their leader on the ground and in the air.
- Migration — Untamed leader ducks periodically fly 80–140 blocks to a new location. Their followers go with them.
- Graceful landing — Ducks descend using flying navigation before switching to ground mode, preventing the sink-into-water bug from 1.x.
- Taming overhaul — Tame the leader duck of a flock to lead the whole group. Tamed ducks follow their owner and are not afraid of predators.
- Animations — Idle, walk, fly, panic, and a rare DAB animation via GeckoLib.
- Config system — Real-time in-game configuration via
/quack config(requires OP/cheats). All values are hot-applied without a restart.
Features
Duck AI
- Ducks form leader/follower chains of up to 3 (leader + 2 followers, then followers chain). Leaders have a particle crown above their head.
- Migration: every few minutes an untamed leader picks a random land target 80–140 blocks away and flies there. Its followers switch to air-follow and come along.
- Panic: any hit causes adult ducks to fly to a random escape point 8–16 blocks away. Baby ducks sprint on the ground instead.
- Ducks avoid monsters, wolves, polar bears, and bees on the ground (suppressed while flying or when tamed).
- Baby ducks follow the nearest adult.
Taming
- Feed seeds to a duck to tame it. Only the leader duck of a flock needs to be tamed — the wild followers trail the tamed leader who follows you.
- Tamed ducks follow their owner when within 12 blocks and stop pursuing when the owner moves further than 20 blocks away.
- Tamed ducks are calm around predators — they will not flee from wolves or monsters.
- Tamed ducks do not migrate.
Spawning
- Spawns across temperate, forest, taiga, wetland, river, and shore biomes.
- Wet biomes (rivers, swamps, beaches) have bonus spawn weight.
- Group sizes and spawn weights are configurable.
