Rancher's Vacpack
A Slime Rancher inspired vacuum gun for Minecraft: suck up items and small mobs, carry them in a tank and shoot them back out — or blast everything away with a pulse of air.
Requires NeoForge 1.21.1 and GeckoLib. Needed on both client and server.

Features
- Vacuum — hold Use to suck in dropped items and small mobs. They swirl along a glowing air vortex and shrink into the nozzle. You keep full movement speed while vacuuming.
- Tank — 4 slots; each holds one kind of item (up to 64) or one kind of mob (up to 10). Captured mobs keep everything: name, health, equipment, even their owner. The HUD next to the hotbar shows spinning 3D models of them.
- Shoot — press Attack to launch one item or mob from the selected slot, hold it to fire continuously. Shots are ragdolls: they fly, bounce off walls and mobs, roll, flop onto their side and get back up. Items hit mobs for a little damage; mobs land unharmed.
- Air stream holding — mobs too big for the tank (big slimes, cows, zombies…) float in front of the nozzle and follow your aim. Shoot to launch them, let go to drop them.
- Pulse Wave — shooting with an empty slot releases a blast of air that sends mobs and items flying and deflects projectiles. Fire it at the ground right next to you for a rocket jump, wind charge style.
- Harvesting — vacuum ripe sweet berry bushes and glow berry vines to pull the berries off.
- Creative Vacpack — a pink vacpack for creative mode: bottomless tank slots, no delay between shots and it vacuums any mob, big or small (except bosses). Not craftable; find it in the creative tabs.
- Feel — animated model, third-person aiming pose, custom sounds and particles; under water the airflow turns into bubbles.

Data pack tags #vacpack:vacuumable and #vacpack:not_vacuumable control what can be picked up.
