2026 Updates
Godot Rapier had 14 releases this year, from v0.8.25 to v0.35. New: Rapier 0.35, Godot 4.7, rope and fixed joints, cross platform determinism fixes, and benchmarks against Box2D, Jolt and Box3D.
Rapier 0.35 and benchmarks
The addon now runs on Rapier 0.35. Both 2D and 3D builds always have the parallel SIMD solver and cross platform determinism enabled.
We compared it with Box2D, Jolt, Box3D and Godot Physics across ten scenes. In 3D, Rapier is first on queries and joints. In 2D, it is the only engine that keeps every scene stable. The v0.35 post has all the numbers, and the benchmarks repo has the tests.
New features
- Rope and fixed joints, in 2D and 3D
- Per-body solver iterations
- Per-joint stiffness and toggling
- Joint warm starting
- Motor position targeting on joints
- State integrate forces
- New project settings for motion recovery, shape casting and query behaviour
Determinism
- Fixed 2D cross platform determinism
- Added cross platform determinism tests
- Saved state congruence
- Fixed a state manager crash on Mac ARM
Godot versions
- Updated to Godot 4.6 and Godot 4.7
- Updated to the latest godot-rust, Rapier and Parry along the way
Fixes
- Fixed 3D joint poses, the 6DOF motor position and limits, and the HingeJoint3D axis
- Fixed PinJoint2D softness to match Godot
- Fixed 2D contacts and shape cast queries
- Fixed the center of mass for forces applied at points
- Fixed Area2D monitorable, the pickable property and freeze mode
- Fixed crashes on startup and on server reload
Balaur
We also announced Balaur, a game engine built around Rapier together with Sébastien Crozet, the author of Rapier.
