🪠 Create Pipes n Physics

⚠️ This mod is currently in beta. Expect rough edges. Please report bugs and share feedback on our Discord! ⚠️ Known Issues There is an issues with the CROWNS mod blocking some of the physics this mod adds. A compat is work in progress

A Create addon that adds realistic fluid physics to pipes and pumps. Fluid flows downhill by gravity, friction limits horizontal range, and pumps interact with elevation.

Features

New Pipe Physics

Create Pipes n Physics adds in a new physics system for pipes and pumps, providing more realistic fluid flow behavior. Therefore, a new pressure/friction system is introduced to simulate the behavior of fluids in pipes. This new behavior naturally enables new physics.

• Fluid flows downhill through pipes without a pump.
• The height difference between source and destination determines pressure and flow rate.
• Siphons work naturally: fluid can travel over a hump as long as the destination is lower than the source.

Pipe Friction

Horizontal pipes create friction that reduces range and flow. Vertical pipes are completely free. The friction model uses diminishing returns, so longer pipe runs don't get punished too harshly.

Pump Physics

Pumps get a gravity assist when pushing downhill and a penalty when pushing uphill. Siphon paths cancel out, only horizontal segments cost friction. Pump range and flow scale with RPM.

Goggle Tooltips

Wearing goggles and looking at a pipe shows a full pressure breakdown: head pressure, friction, gravity assist, net flow rate, and remaining reach in blocks.

Sable Support

Optional integration with Sable for rotating structures:

• Fluid tanks gain dynamic weight based on fill level and fluid density
• Tilted fluid rendering with wave simulation
• All pipe physics recalculate automatically on rotating sub-levels

Fully Configurable

Every physics value is configurable: gravity pressure, friction, pump gravity factor, angle thresholds, tank mass, and more. Every feature can be toggled independently.

Dependencies

• Create (required)
• Sable Companion (optional, for sub-level pipe physics and fluid rendering)
• Sable (optional, for dynamic tank mass)
