A Unity project featuring a 2D character with procedural animation driven by inverse kinematics (IK). The animation is controlled programmatically without pre-made keyframes, enabling smooth, dynamic motion based on logic and math.
- ✅ Procedural Walking using alternating foot placement with center of mass balance detection
- ✅ Dynamic Foot IK with smooth arc interpolation and step anticipation
- ✅ Head Tracking: character looks at the cursor with natural head tilt
- ✅ Automatic Flipping: direction-aware flipping of character and limbs
- ✅ Modular Movement: fully physics-based character controller
- ✅ Gizmos Visualization for step targets and debug purposes
The walking algorithm works by checking if the character's center of mass is within the span of the two feet. If not, it triggers a step using a raycast to find the ground. The foot then lerps in an arc toward that point. The other foot waits its turn until the current step completes.
The head rotation system tracks the cursor only when idle and tilts naturally with the terrain using the spine's raycast normal.
| Script Name | Description |
|---|---|
ProceduralWalking.cs |
Handles logic for walking by stepping each foot based on balance and timing |
FootPositioner.cs |
Computes step paths for individual feet using raycasts and overshoot logic |
PlayerMovement.cs |
Simple Rigidbody2D-based movement controller for the character |
HeadMovement.cs |
Makes the head follow the mouse with spine rotation and vertical bobbing |
