• added support for high refresh rate displays with fixed timestep in Matter.Runner
• added support for sub-stepping for higher quality simulations in Matter.Runner
• changed to a fixed timestep by default in Matter.Runner
• improved frame pacing and average performance up to ~6% (see #1238)
• reduced average memory usage up to ~30% (see #1238)
• reduced memory garbage collection
• bug fixes and improvements see changelog

Changes ✲

See the release compare page and the changelog for a detailed list of changes.

Migration ⌲

Matter.Runner related changes #1254:

• Matter.Runner now defaults to a fixed deterministic timestep and support for non-fixed timestep is removed
• optionally set your performance budgets runner.maxFrameTime (see docs)
• note that Matter.Runner can now call zero, one, or multiple engine updates and events per display frame (see docs)
• if needed set up your polyfill for window.requestAnimationFrame
• see Matter.Runner updated docs throughout

Performance related changes #1238:

• Matter.Collision use collision.supportCount instead of collision.supports.length for active support count
• Matter.Pair use pair.contacts instead of pair.activeContacts
• Matter.Pair use pair.contactCount instead of pair.contacts.length for active contact count
• Pair.id format has changed

▲.● matter.js 0.18.0

Release notes for 0.18.0. See the release readme for further information.

Highlights ✺

• Up to ~40% performance improvement (on average measured over all examples, in Node on a Mac Air M1)
• Replaces Matter.Grid with a faster and more efficient broadphase in Matter.Detector
• Reduced memory usage and garbage collection
• Resolves issues in Matter.SAT related to collision reuse
• Removes performance issues from Matter.Grid
• Improved collision accuracy
• Improved API and docs for collision modules
• Improved documentation pages
• Added note about avoiding Webpack performance problems

Changes ✲

See the release compare page and the changelog for a detailed list of changes.

Migration ⌲

• Behaviour and similarity is in practice the same (a fractional difference from improved accuracy)
• API is the same other than:
  • Matter.Detector replaces Matter.Grid (which is now deprecated but will remain for a short term)
  • render.options.showBroadphase is deprecated (no longer implemented)
  • Matter.SAT is renamed Matter.Collision
  • Matter.SAT.collides is now Matter.Collision.collides with a slightly different set of arguments
