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-organize 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.
• GUI 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.
