Smart Zombies Mobs

Smart Zombie

A Minecraft Fabric mod that gives zombies brains (1.21.1) — zombies are no longer mindless targets that just chase you. They will mine through walls in their way, parkour across gaps, spawn in hordes, carry skeletons as turrets, hurl creepers at you, flee for their lives when a creeper ignites, call for backup the moment one of them spots you, pick up weapons and food off the ground, smash your torches, trample your crops, and attack your livestock — all with randomized size and combat stats.

💡 Tip: You'd better build a house to protect yourself (zombies won't destroy most building blocks).

Key Features

• 🧱 Wall Mining — Blocked by a wall? They mine through it and keep chasing
• 🏃 Mob Parkour — 18 mobs auto-jump across gaps and ledges
• 👥 Horde Spawning — zombies spawn in packs of 2–3; the night is more dangerous
• 💣 Creeper Tactics — carry skeletons for shooting / throw creepers as bombs / every zombie near an ignited creeper flees the blast
• 📢 Alert Calls — when one zombie spots you, allies within 64 blocks join the hunt
• ⚔️ Loot Pickup — Zombies pick up tools, weapons, and armor (pick up a pickaxe → start mining)
• 🕯️ Torch / Glass / Fence Breaking — Idle zombies smash your lighting, your windows, and your fences
• 🌾 Crop Breaking & Animal Attacks — Zombies trample farms and strike livestock
• 🍖 Meat Eating & Healing — Hurt zombies eat meat to heal; more nutrition = more HP
• 🌧️ Drowned on Rainy Days — on rainy nights, drowned with tridents can spawn in the open
• 🎲 Randomized Attributes — Giant zombies are tanky and hard-hitting but slow; mini zombies are lightning-fast
• 👁️ Enhanced Detection — 48–64 block targeting + 32 block wall-hack (x-ray)
• ⚖️ Difficulty Scaling — more zombies on Hard, peace and quiet on Peaceful
• ⚙️ Fully Configurable — Grouped config, bilingual comments, adjustable ranges on every parameter

Features

🧱 Core AI

👥 Horde Behavior

• Horde Spawning — natural zombie spawns have a zombieGroupChance (default 20%) chance to bring 2–3 buddy zombies (the classic 1.12 group-spawn mechanic returns; buddies respect the 24-block no-spawn radius)
• Drowned on Rainy Days — in rain under open sky (non-dry biomes), zombies have a drownedRainChance (default 15%) chance to be replaced by drowned carrying vanilla tridents / fishing rods / nautilus shells
• Difficulty Scaling — difficultyScaling (default true) multiplies horde & drowned chances by the difficulty factor (Peaceful 0 / Easy 0.75 / Normal 1.0 / Hard 1.5); higher difficulty = more zombies

🧟 Recruit System

• Skeleton Carrier — Zombies carry skeletons on their shoulders; the skeleton targets independently with a boosted 32-block follow range and faster firing (a "skeleton turret"); the zombie slows down under the load
• Creeper Thrower — Zombies carry creepers and hurl them at targets along a ballistic arc, ignited ("creeper bomb"); active throws are range-limited (horizontal 24 / vertical 32, creeperThrowRangeHorizontal / Vertical); when the creeper on their back ignites, they pause 0.5s (creeperIgniteThrowDelay) then throw it away to save themselves (never range-limited); either taking damage → instant dismount
• Master toggle recruitEnabled + per-type toggles recruitSkeleton / recruitCreeper

🎲 Randomized Attributes

Zombies spawn with randomized size (0.6×–2.0×, normal distribution ±35%); speed/health/attack are 100% derived from size:

• Base multipliers / variation / linkage scale all configurable; speed & size have hard caps (prevents extremes)
• Toggle attributeVariation

⚔️ Equipment Randomization

• Random Tools — Zombies randomly equip a pickaxe/axe/shovel/hoe in the offhand (materials stone/iron, type/chance configurable), possibly enchanted (Efficiency/Fortune/Silk Touch/Unbreaking/Mending)
• Trident — Zombies no longer spawn holding tridents (prevents player trident farms); dropped tridents are still picked up and equipped

📈 Spawn Boost

• Zombie spawn weight adjustable (vanilla 100 → default 200); zombies dominate the dark
• Spawn cap multiplier spawnCapMultiplier (default 1.5: monster cap 70 → 105) — zombies have the highest weight and benefit the most
• Spawn frequency multiplier spawnFrequencyMultiplier (default 1.0 = vanilla, max 3.0 = 9 attempts per chunk per tick) — faster spawning
• Horde spawns zombieGroupChance (default 0.2) + rainy drowned drownedRainChance (default 0.15), scaled by difficultyScaling

⚙️ Config System

• Main config config/smartzombie.json: all features organized in groups (master / mining / torch breaking / crops & animals / meat eating / detection / spawn / equipment / attributes / recruit / debug), every option with bilingual comments, adjustable range hints on numeric parameters (prevents out-of-range values), and invalid values auto-clamped on load
• Parkour list config/mobs_attempt_parkour/config.json: customize which mobs get the parkour AI (mobId + priority)
