EasyIK 1.0.0 Tools 4.6 Community

EasyIK is a universal 2D inverse kinematics addon for Godot 4.6+.
Add it to your project once, then attach a single node to any limb to apply IK — with full solver flexibility and zero rigging boilerplate.

Whether you are building a side-scrolling platformer, a top-down action game, a narrative adventure, or any project that needs natural character animation, EasyIK gives you four pluggable solvers (2D LookAt, Two Bone IK, CCDIK, and FABRIK out of the box), per-joint angle constraints with live gizmo visualization, automatic flip-proof bone rotation that survives scale.x = -1, soft IK for smooth motion, target tracking with critical damping, a fully customizable editor gizmo, and a complete IK API that just works.

Works as a single node per limb — no skeleton modification setup, no custom rig attachment required. Simply assign bones, set a target, choose a solver, and await. Add solvers at runtime, configure joint constraints once, adjust gizmo colors on the fly, and let EasyIK handle everything else. The solver system is fully extensible and documented for custom kinematics implementations.

EasyIK — Four solvers, one node, flip-proof by design.
