Calm Bubbles

Calm Bubbles is a tiny NeoForge 1.21.1 mod that disables the push/pull effects of vanilla bubble columns (soul sand / magma).
Visual bubbles remain — but no more movement for players, mobs, items, or boats.

What it does

Cancels BubbleColumnBlock#entityInside, so bubble columns keep their visuals but stop applying vertical velocity (no elevators, no siphons).

Use cases (hidden perks)

• Worldgen packs: many worldgen mods (e.g., Terralith, WWOO) place bubble columns decoratively. With Calm Bubbles, those spots stay pretty without shoving you around — no more accidental elevators/siphons during exploration.
• Underwater exploration: bubble columns become safe visual beacons rather than hazards. It’s easier to hover near them, manage breath, or set up air pockets (doors/trapdoors/signs) and conduits without being pushed/pulled.
• Mapmaking & builds: perfect for set-pieces and underwater POIs where you want bubble ambience but no forced movement on entities.

Why?

• Minimalist & server-friendly
• Zero config needed
• Keeps vanilla visuals

Install

Drop the JAR in your mods/ folder.
Works if installed server-side only (clients can stay vanilla).

Compatibility

• No dependencies.
• May conflict with mods that change bubble column behavior in the same method.

A note from the author

This is my very first Minecraft mod. I’ve got many ideas and ambitions ahead—this is where it starts.
I’ll do my best to keep Calm Bubbles up to date, adapt it when needed, and keep shipping my other projects as they grow. Thanks for trying it out!

Optional Feature Plans (roadmap)

• Server config toggles: disablePush=true/false, disablePull=true/false
• Runtime switch: gamerule/command (e.g. /calmbubbles toggle)
• Per-entity rules: allow/deny lists (players only, exclude items/boats, etc.)
• Side control: force server-only vs. require clients
• Data/JSON config: simple file under serverconfig/
• Tiny API hook: let other mods override behavior when needed
