Create: Mob Farming

An addon that gives Create the pieces it's missing for mob farms:

• Entity Filter — describes which mobs you care about
• Mob Gate — only lets those ones through
• Critterport — puts live mobs on a chain conveyor and sends them somewhere else
• Mechanical Blade — kills them at the end of it

There's no all-in-one grinder block here, you still have to build the farm. Fans, water and gravity move the mobs around, same as they move everything else in Create.

All four blocks have Ponder scenes. Hold W over them if you'd rather see it than read it.

⚙️ Mechanical Blade

Put it on a contraption and it cuts whatever it sweeps through. Sitting still it does nothing.

• Damage comes from how fast the blade is actually travelling, not the RPM of the shaft. A blade mounted six blocks out from the axis hits a lot harder than one next to it, so it's worth thinking about when you lay the thing out.
• Enchant it before you place it and the enchantments work normally, Looting included.
• Enchanted blades keep the glint on their cutters once placed, which saves you taking a farm apart to find out which blade you enchanted.
• Drops land in mounted storage. XP is kept as Nuggets of Experience instead of dumped on the floor.
• Filter a Contraption Controls with a blade and it'll arm or disarm every blade on the contraption at once.
• Most of the numbers are in the server config if you want to tune them.

🏷️ Entity Filter

This is the part everything else is built on. An item that holds a description of which mobs you mean, which you then slot into the things that need to know.

What it can match:

• As many entity types and tags as you want
• Narrowed by Adult/Baby, Tamed/Untamed, Named/Unnamed, Hostile/Non-Hostile
• Flipped round to a deny list if that's easier to express

Three ways to set one up, since none of them is best in every situation:

1. Sneak-right-click a mob to add its type
2. Search the full list in the UI
3. Hit a preset — Hostile, Passive, Undead, Arthropod, Aquatic

Those five presets are entity tags, so if a modpack disagrees with where I've put something, a datapack can fix it.

🚪 Mob Gate

A grille that mobs matching the filter can walk through and everything else can't. It doesn't move anything itself, you're expected to have a fan or water pushing things at it.

• Place them next to each other and they merge into one gate up to 3x3, sharing a single filter and a single redstone lock.
• Players only get through if the filter lists them explicitly.
• Dropped items and XP orbs pass any unlocked gate, so loot doesn't stack up on the wrong side.
• Fan airflow carries straight through the grille, which is what makes the whole fan-against-a-gate setup work.
• Baby animals stay stuck until they grow into whatever the filter is asking for. That's a sorting mechanism if you want it to be.
• It's four voxels deep rather than a full block, so the barrier and the filter slot are both on the face you can see.

🐄 Critterport

Live mobs on Create's Chain Conveyors. Give a station an address, tell a different station to send there, and anything that wanders into its mouth gets hauled across the base hanging off the chain.

• The mobs stay real entities the whole way. Health, names, armour, tame state, age and whatever data other mods have attached to them all survive the trip. That's the main reason to use this over any kind of capture item.
• They properly hang and swing while they travel. Slow chain and they sway a bit, fast chain and they trail back towards horizontal, corners throw them wide, stopping the chain sends them swinging forwards. It looks ridiculous with a cow and I've made no attempt to fix that.
• Stations route themselves through junctions and won't pick up a mob they can't currently deliver, so a broken or blocked network leaves your livestock standing at the station instead of quietly losing it.
• Nothing in the system deletes a mob. Including one whose destination gets broken halfway through the journey.
• Addresses are separate from Create's package addresses, so Critterports and Frogports won't get confused with each other.
• No filter and no storage in the station, deliberately. That's what Mob Gates are for.
