Trace Function Library – Advanced Tracing Utilities for Unreal Engine
Supercharge your gameplay systems with a powerful suite of trace and sweep functions tailored for real-world game logic. The Trace Function Library provides modular, easy-to-use Blueprint-callable functions for detecting hits, surfaces, visibility, and spatial relationships in a variety of contexts without the boilerplate.
Whether you're building an RTS, third-person adventure, or physics sandbox, this plugin equips you with trace tools that just work.
✅ Key Features
Camera-Based Tracing: Easily perform line, sphere, or multi-traces from first-person, third-person, or RTS-style perspectives.
Shape Sweeps: Line, sphere, box, and capsule sweep support with debug visuals.
Ground & Ceiling Detection: Grab precise surface points above or below any actor — perfect for foot placement or obstacle detection.
Socket Traces: Trace outward from any socket on a skeletal mesh.
Cone Tracing: Multi-segment cone-shaped field of view logic — ideal for AI detection or visibility checks.
Debug-First Design: Optional debug lines, points, and durations for every function to simplify iteration and visual testing.
Perfect for solo devs, prototypers, and advanced system designers alike — cut out the repetitive setup and get straight to results.
