Apply mass-spring dynamics to individual joints or joint-chains while supporting joint rotation limits without needing to go through an external physics engine. Simulate with forces, inertia, IK etc.
Dynamic Joint Chain Pro v1.0 (03 Jun 2022) (Latest version)
“Sharing is caring”
Description
A fast, robust mass-spring dynamics system which supports JOINT ROTATION LIMITS in its dynamics simulation, making it the only particle dynamics solution of its kind to solve for joints with strict hinge and swing-twist limits cheaply and continuously without needing to go through an external physics engine.

Features:
– Dynamic Joint: simulate individual joints with mass-spring dynamics under gravity, inertia or spatial-relation targets, limited by any authored joint limits.
– Dynamic Chain: simulate joint-chain hierarchies with mass-spring dynamics under different forces while preserving distance constraints and limited by any authored joint limits.
– Dynamic Transform Filter: Move & rotate a gameobject towards a target transform’s position and rotation while simulating mass-spring dynamics to generate secondary motion & oscillations.
– Layered forces: simulate procedural motion using [Constant / Sin-Wave / Perlin-Noise] progression modes with custom amplitudes, frequency along time and frequency along chain to generate ‘tentacle-like’ motion
– Elastic Stretch: simulate stretchy bone-lengths in dynamic chains under forces controlled by stretchiness and stiffness values
– Custom Distance Constraints: add bespoke distance constraints between any two joint-particles even if they don’t share a hierarchy.
– Dynamic Colliders: limit motion of dynamic-chain particles. Generate directly from Unity’s native colliders, or set collision against a layer
– Dynamic Inverse Kinematics: drive end particles towards their targets in a physical way with full CCD-like IK solutions while still being affected by forces/collisions/dynamic secondary motion.
– Dynamic Properties such as damping, drag, force and spring strength, start and end weights, particle radii, surface friction with colliders etc.
Package includes several demo scenes showcasing the features. Please refer to the tutorial videos to get started.
