Author: FoamySlime
Project Type: Experimental / Showcase Mod

🎬 About the Project
This mod was created for the FoamySlime YouTube Project as a tool for Minecraft Copper Golem Event.
It allows you to spawn massive rings of Copper Golems around the player — thousands at once — using simple commands.
The mod demonstrates:
- Real-time server tick scheduling
- Batch-based entity spawning (safe multi-tick load)
- Optional invisibility and magma base generation
🧱 Commands
| Command | Description |
|---|---|
/ring_spawn [amount] [distance] [magma] [invisible] |
Starts spawning Copper Golems in a perfect circle around the player. |
/ring_stop |
Stops all active ring spawns in the current world. |
/ring_count |
Counts all Copper Golems currently loaded in the world. |
⚠️ Performance Warning
READ THIS BEFORE USING
- This mod is intended for testing and cinematic experiments, not normal survival gameplay.
- Spawning thousands of entities WILL cause lag, even with AI disabled and invisibility on.
- Every Copper Golem still exists in world memory — invisible ≠ unloaded.
- For massive tests (>100k), run on a dedicated test world or use superflat void presets.
- Adjust
BATCH_PER_TICKin the source if your server cannot handle large bursts.
🧠 Invisible mobs still consume tick cycles for collision and data checks — use responsibly!
