FlexiPhysi is a complete active ragdoll solution designed to bring life and unpredictability to your characters without sacrificing control.


Instead of relying purely on keyframed animation or unstable physics setups, FlexiPhysi bridges both worlds. It converts animation data into physically-driven motion in real time, allowing characters to react dynamically to impacts, environment, and player input—while still preserving the intent of your animations.


The system is built with usability in mind. You can set up a fully functional active ragdoll in minutes, without diving into complex joint configurations or writing custom physics code. Whether you're creating a physics-based sandbox, a character-driven indie game, or just want more natural movement, FlexiPhysi adapts to your workflow.


What makes FlexiPhysi stand out is its balance between chaos and control. Characters feel grounded, responsive, and expressive—without the jitter, instability, or “broken puppet” look common in many physics systems.


Key Use Cases:

  1. Physics-based character controllers
  2. Sandbox and emergent gameplay
  3. Procedural animation systems
  4. Stylized or semi-realistic movement

Fully Customizable:

Every aspect of the system can be tuned—from force strength and responsiveness to joint behavior and balance logic—giving you full control over how your characters feel.
