📦 Description
This (unofficial) really small, simple and lightweight datapack automatically replaces (from mod) DragN's Livestock Overhaul horses with SWEM (Star Worm Equestrian) horses for any world or server — completely in the background and without any need for command blocks.

It runs every tick and uses an optimized execute command to detect (from mod) DragN's Livestock Overhaul horses and summon their SWEM equivalent at the same position.

🧠 Designed for modded servers or singleplayer worlds using the Star Worm Equestrian Mod (SWEM), where you want to fully transition from (mod) DragN's Livestock Overhaul horses to SWEM's horses.

No commands... No setup...
Just horses that work the way you'd expect in a SWEM-based world.

How it works

(video from vanilla horses datapack but it works the same)

🛠️ Compatibility

✅ Tested with Minecraft 1.20.1 (requires SWEM mod).
⚠️ Should be compatible with 1.18.2 (same datapack structure - but not guaranteed & not tested).

If you encounter any issues or want to suggest improvements — just let me know (kindly, please!) and leave a comment!

🔧 How to Install

Download the .zip file.
Drop it into your world's /datapacks/ folder.
Start your world or server.
Run /reload (if needed).
Done!

💡 Honestly — this is something the original mod should have done from the beginning. Or at the very least offered as a simple config toggle (true/false). But for some unknown reason, it wasn’t included. Why? I don't know... So this datapack steps in to do exactly what SWEM overlooked: a smooth, automatic replacement of (mod) DragN's Livestock horseshorses with SWEM horses.

✨ Feel free to use this datapack in your own world, server, modpack
Just enjoy it and ride off into the blocky sunset. 🐎🌅
