A dozen focused modules. Zero spaghetti.** Rigonix is a modular third person character controller for Unity, built for developers who want a controller they can actually *read*. Walk, run, sprint, crouch, go prone, jump with real arc physics, aim, dodge, climb stairs, plant feet on uneven ground with IK, react to surfaces underfoot, pick things up, and collapse into a physics ragdoll on death — every behaviour a small, self-contained module behind its own inspector tab. [**⬇️ Get Rigonix on the Unity Asset Store →**](https://assetstore.unity.com/publishers/rigonix) {% hint style="info" %} **New here?** The fastest path is the Quickstart — an FBX to a walking, jumping character in about a minute. {% endhint %} ## Why Rigonix? Most character controllers grow into a single 4,000-line class that nobody dares touch. Rigonix takes the opposite bet: **every capability is a module**. Need to tweak how jumps feel? Open the Airborne tab. Footsteps sounding wrong on grass? That's the Footstep system. Nothing is buried, nothing is entangled, and you only pay attention to the parts you care about. And because the character's *body* is separated from whatever *drives* it, the same locomotion, jumping, and ragdoll code powers a keyboard-and-mouse player and a camera-less AI agent alike — without a line of duplication.


🏃 Fluid Locomotion	Walk, run, sprint, crouch, prone, aim, and strafe — with smooth stance transitions and automatic stair handling.
🤸 Physics Ragdoll	Auto-built from the humanoid skeleton, with presets from heavy-and-grounded to full arcade chaos.
🧩 Modular by Design	Every behaviour is an isolated module behind its own inspector tab. Read it, tweak it, or ignore it.

## What's in the box Everything below ships in the base controller — no add-ons required:

System	What it does
Input	One device-agnostic intent surface for keyboard, mouse, gamepad, and touch — the single source of truth every module reads from.
Locomotion	Speeds, stances, strafe/free movement, rotation, and stair-stepping.
Airborne	Gravity, ground detection, coyote time, and context-aware standing / walking / running jumps.
Camera	A self-contained third-person rig that re-frames for crouch, prone, aim, and sprint — or swap in Cinemachine.
Ragdoll	Auto-built physics ragdoll with tunable presets and a bone builder.
IK System	Foot, head, and torso IK that keeps the character grounded and looking alive.
Footsteps	Surface-aware audio, particles, and decals driven by animation events.
Interaction	A tiny interface that makes any object interactable — press, hold, tap, or automatic.
And more	Health & stamina, inventory, dodge, emotes, teleport, and audio.

## Built for the long haul {% columns %} {% column %} **Buyer-safe by design.** Deprecated fields are preserved and clearly labelled rather than deleted, so a Rigonix update never silently breaks your existing prefabs. {% endcolumn %} {% column %} **Add-on ready.** Melee, AI, and shooting add-ons attach through defined seams and never modify the core — so the controller you rely on stays stable. {% endcolumn %} {% endcolumns %} ## Start building


⚡	Quickstart	FBX to a playable character in a minute.
🧩	The Modules	Every module, explained.
🔌	Cinemachine	Drop in a Cinemachine rig, no core edits.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://rigonix3d.gitbook.io/rigonix3d-docs/readme.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
