Promenad

A purely procedural animation system that can walk and hold hands. Created in the spring of 2021 as the specialization course at The Game Assembly.

Feature highlights

Inverse kinematics animation system constrained by hinge joints. Supports paths with multiple consecutive target positions (green lines and spheres).

Proceduraly generated walk cycle supporting a wide range of movement speeds. Movement animation automatically adjusts to current speed and feet rarely drag/slide noticably.

Foot placement handles uneven terain with some grace (altough it's far from perfect).

Despite popular belief I think we have to little hand holding in contemporary videogames.
