Practical tips for developers

  1. Use continuous integration with the target compiler/SDK versions used by your build pipeline to detect incompatibilities early.
  2. Profile the physics step—tune solver iteration counts, collision margins, and sleeping parameters to balance performance and stability.
  3. Prefer convex collisions for dynamic objects; use triangle meshes only for static geometry to reduce cost.
  4. Export and reimport assets with consistent scale and units; mismatched scale is a common source of unstable simulations.
  5. When updating compilers, enable strict floating-point consistency settings if deterministic behavior is required across platforms.
  6. Keep collision layers/masks minimal to reduce pair testing overhead.
  7. Use provided visual debugging tools during development to verify contact normals, constraint frames, and broadphase behavior.

When to keep vs. upgrade

  • Keep: active projects tightly coupled to this version, where re-certifying behavior is costlier than staying.
  • Upgrade: new projects, cross-platform modern builds, or where ongoing support, security, and performance improvements matter.
