✳✲✱ Official Force2D v3.1.3 ✱✲✳ Fast, realistic, easy-to-use 2D rigid-body physics engine for games! ★☆ Feel free to use — no credits required! ★☆ But special credit to @TheLogFather for the triangle filler [ What's New? ] - New Features • revolute joints • distance joints • prismatic joints • mouse joints • weld joints - Improved Stability • K-matrix impulse solver • Block solver (multi-contacts) • Baumgrate stabilization - Improved Performance • Sleep islands • Warm start • Dynamic BVH ★☆ Special thanks ★☆ @komafami helped a lot while I was struggling to develop this physics engine. [ Abouts ] • Released on 2026/5/12 (Age 20) • A 2D rigid-body physics engine based on Box2D algorithms • May lag heavily in Scratch, so TurboWarp is recommended • thumbnail generated by Gemini • sprite icon from @Chrome_Cat [ Versions ] 2026/06/24 - v3.1.3 fixed joints not working when rigids are sleeping 2026/05/25 - v3.1.2 fixed the rigids removal bug by rebuild the BVH tree / Hash grid, also fixed drag object with force mouse position bug and BVH renderer zooming bug 2026/05/14 - v3.1.1 weld joint added, and fixed the joint glitches bug 2026/05/12 - v3.0.1 fixed joint connected sleeping bug and warm start id pairs bug 2026/05/12 - v3.0.0 initial version #physics #engine #rigid #body #rigidbody #force2d
