There are a few minor breaking changes, see this document.

New functionality

  • Added PlaneShape. An infinite plane. Negative half space is considered solid.
  • Added TaperedCylinderShape. A cylinder with different top and bottom radii.
  • Added EmptyShape. A shape that collides with nothing and that can be used as a placeholder or for dummy bodies.
  • Use MeshShapeSettings::mPerTriangleUserData at about 25% memory increase to get per triangle user data through MeshShape::GetTriangleUserData
  • Added Shape::GetLeafShape to be able to get a leaf shape given a sub shape ID
  • Added HeightFieldShape::GetSubShapeCoordinates to get the triangle coordinates of a particular sub shape ID
  • Split back face mode between convex/triangles for ray casts. This allows you to e.g. have meshes that do give back face hits while convex shapes don't.
  • SoftBodyManifold now returns sensor contacts separately. Before this change, there was a limit of a single colliding body per soft body vertex. If the closest body happened to be a sensor this effectively disabled the collision with the world and caused artifacts. We can now also detect multiple sensor contacts per soft body and they are returned through a new interface SoftBodyManifold::GetSensorContactBodyID.
  • Added support for running Jolt with ThreadSanitizer.
  • Added support for using ScaledShape inside CharacterVirtual.
  • Added ability to save/restore a simulation in parts using StateRecorder::SetIsLastPart. Also added StateRecorderFilter::ShouldRestoreContact to allow selective restoring of contacts.
  • Added JPH_DEBUG_SYMBOL_FORMAT cmake option. This allows switching from the default dwarf symbol format to e.g. the source-map format for emscripten, which speeds up compilation.

Bug fixes

  • Fixed an issue where enhanced internal edge removal would throw away valid contacts when a dynamic compound shape is colliding with another mesh / box shape.
  • Fixed an issue where the bounding volume of a HeightFieldShape was not properly adjusted when calling SetHeights leading to missed collisions.
  • Workaround for CMake error CMake Error: No output files for WriteBuild! when using the 'Ninja Multi-Config' generator.
  • When a height field was created where SampleCount / BlockSize is not a power of 2 and a soft body touched the right or bottom border of the height field, the application would crash.
  • Fixed a link error ld: error: undefined symbol: pthread_create on FreeBSD.
  • Fixed missing files ConfigurationString.h and SoftBodyUpdateContext.h when running cmake --install.
  • Fixed various missing header files when running cmake --install when ENABLE_OBJECT_STREAM=OFF.
  • When using cmake --install to install a shared library on Windows, the dll is installed in the 'bin' folder now.
  • Fixed cmake warning: Policy CMP0177 is not set: install() DESTINATION paths are normalized.
  • Fixed unresolved symbol '__emutls_v._ZN3JPH11PhysicsLock6sLocksE' when compiling Jolt as a shared library with MinGW.
  • Added workaround for issue where Firefox has problems with the _mm_blendv_ps intrinsic when compiling to WASM.
