About this Mod
🐴 Random Mob Riders
Turn your world into pure chaos.
Random Mob Riders is a Fabric mod for Minecraft 1.21.11 that makes mobs randomly ride each other — just like a command block system, but fully implemented in code for better performance and seamless gameplay.
🔥 What This Mod Does
- Mobs randomly stack on top of each other
- Works automatically around players
- Uses logic inspired by advanced command systems
- Creates unpredictable and hilarious gameplay moments
You might see:
- A zombie riding a cow 🐄
- A skeleton tower forming out of nowhere 💀
- Completely unexpected mob combinations
⚙️ How It Works
- The mod continuously runs logic similar to a repeating command block
- For each player:
- A random nearby mob (within 128 blocks) is selected
- The mob is tagged internally to prevent reuse
- Another valid mob is selected
- The first mob mounts the second
This results in natural, evolving stacks of mobs across your world.
🧠 Technical Details
- Replicates command-style entity selection:
- Random sorting (sort=random)
- Limit-based selection (limit=1)
- NBT-based filtering
- Uses nested NBT tags (
data.spawned) to track processed entities - Only affects mobs with AI (no players or invalid entities)
