Description

OmniWalk is a high-performance C++ framework for Unreal Engine 5.4+ that delivers "Impossible Locomotion".

Designed to replicate the high-fidelity magnetism found in titles like Ratchet & Clank and Dead Space, it allows any character to traverse arbitrary geometry — walls, ceilings, pipes, and planets — with zero technical friction.

While UE5.4 introduced native multi-directional gravity, OmniWalk solves the remaining "showstopper" problems: camera gimbal-lock, control inversion, triangle-normal jitter, and complex input remapping.

🚀 The "Zero-Config" unified component

Unlike competing frameworks that require rebuilding your character from a specific parent class, OmniWalk features a unified component architecture.

Drop-In Integration: Drag the OmniWalkPro component onto any ACharacter (Pawn, MetaHuman, Synty, etc.).
Auto-Hijack Logic: Upon BeginPlay, the component automatically configures Pawn settings (Yaw usage, floor angles), injects a Camera Stabilizer, and intercepts the Input Buffer to project world-space movement onto local surface planes.

🧠 Key Technical USP's

Native 5.4+ Gravity Integration: Leverages the re-designed CharacterMovementComponent gravity architecture for frame-perfect physics — not forces-based hacks.
Gimbal-Free Camera Solver: A custom C++ Camera modifier resolves the "Euler Singularity." Mouse/Stick look remains intuitive and non-inverted, even when standing upside down on a ceiling.
Arbitrary Surface Adhesion: No Volumes required. Walks on any StaticMesh, DynamicMesh, or Landscape normal via optimized trace-averaging.
Input Projection Technology: Automatically "steals" world-space movement input and flattens it against the current surface normal, preventing the character from becoming "stuck" against vertical walls.
Slate Telemetry Debugger: A dedicated Editor window (Window > OmniWalk Debugger) provides real-time telemetry on gravity vectors, alignment strength, and trace hits.

🛠 Technical Specifications

Performance: All core logic is written in C++ and executes in TG_PrePhysics, ensuring zero latency between surface detection and movement integration. Requires the Enhanced Input plugin to be enabled.
Orientation Math: Uses Quaternions (QInterpTo) and Slerp-normalization to handle 360-degree transitions without gimbal flips.
Procedural Demo Included: Includes a C++ Helix-Generator that constructs "impossible" walking paths at runtime to demonstrate system stability across extreme centripetal forces.

📋 Package Contents

Runtime Module: Core Adhesion Component, Camera Stabilizers, Input Hijacker, and World Subsystem.
Editor Module: Slate UI Telemetry and Debugging tools.
Source Code: Fully commented C++ code.
Example Content: Procedural demo level and a "Zero-Touch" implementation guide.

Technical Details

Features:

Native 5.4+ Gravity: Utilizes CharacterMovementComponent::SetGravityDirection for frame-perfect physics integration.
Arbitrary Adhesion: Walk on any Static Mesh, Dynamic Mesh, or Landscape via optimized surface-normal tracing.
Gimbal-Free Solver: Custom C++ Camera Modifier resolves the Euler Singularity, preventing view-locking at ±90° pitch.
Input Hijacking: Intercepts raw movement input and automatically re-projects vectors onto the current surface plane.
