A 2D and 3D physics engine plugin for the Godot game engine, built on the Rapier physics library and Salva fluids simulation. It serves as a drop-in replacement for Godot's built-in physics, offering better stability, performance, liquids, determinism, and state serialization.

Use cases

• replace Godot's built-in physics engine with a more stable one
• simulate liquids and fluids in 2D or 3D games
• build deterministic multiplayer or replayable physics simulations
• save and restore physics state in a game
• fix ghost collisions and improve object stacking
• run physics on desktop, mobile, and web builds

When to choose

• you use Godot 4 and need more stable or faster physics than the default engine
• your game requires fluid or liquid simulation
• you need deterministic physics for networking, replays, or lockstep simulation
• you want a drop-in replacement with minimal code changes

When to avoid

• you use Godot 3 or a non-Godot engine
• your project is simple and the default Godot physics is sufficient
• you need deep customization of the physics solver internals in a language other than Rust
