Fluid Flow Controller

🧊 FluidFlowController

Disable Water & Lava Flow in Minecraft (Fabric 1.21.1)

FluidFlowController is a lightweight Fabric mod designed for server administrators ~~~~who want full control over fluid behavior.
It completely disables water and lava flow, along with their block updates and scheduled ticks — keeping the world static, stable, and lag-free.

💡 Features

• 🚫 Prevents all fluid propagation (no flow, no spreading)
• ⚙️ Cancels scheduled fluid ticks for optimal performance
• 🔒 Blocks block updates caused by water or lava
• 🧩 Includes an in-game command /ffc to toggle flow in real time
• 💾 Saves configuration automatically in config/ffc.json
• 🌐 Compatible with Fabric, Fabric-based Arclight, and dedicated servers

🧭 Commands

/ffc water on|off 
/ffc lava on|off

These commands can be used by server operators (permission level 3 or higher) to enable or disable water and lava flow dynamically without restarting the server.
If Luckperms is installed, the permission node ffc.toggle can be used to grant access to these commands.
