🎬 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_TICK in the source if your server cannot handle large bursts.

🧠 Invisible mobs still consume tick cycles for collision and data checks — use responsibly!

---

💡 Tips

• Use this mod in Creative Mode only.
• Best used with F3 + Shift + F3 graphs visible for tick profiling.
• Try setting total to smaller numbers (e.g., 1000) before pushing limits.
• If the world slows down heavily, execute /ring_stop
