2D and 3D physics engine for the Godot game engine.

Godot Rapier Physics is a 2D and 3D physics drop-in replacement for the Godot game engine that adds stability through rapier and fluids through salva.

Installation

Automatic (Recommended): Download the plugin from the official Godot Asset Store using the AssetLib tab in Godot:
Manual: Download the latest github release and move only the addons folder into your project addons folder.

After installing, go to Advanced Settings -> Physics -> 2D or 3D. Change Physics Engine to Rapier2D or Rapier3D.

Limitations

SeparationRayShape missing.
SoftBody3D missing.
ConcavePolygonShape3D, HeightMapShape3D, 3D joints.
Cross platform determinism.
Double builds.
Liquids Missing.
No support for asymetric collisions (eg. object 1 hitting object 2 but object 2 not hitting object 1). More info here Rapier Collision groups and solver groups. This is the exact check rapier does: (A.layer & B.mask) != 0 && (B.layer & A.mask) != 0
Friction works differently than it does in Godot. The current formula is: friction is multiplied by other friction, bounce is taken the max value.
Setting Center of Mass to Custom or Custom Inertia doesn't work right now.
On web you cannot run both Rapier2D and Rapier3D at the same time.
