Smart Cone Trace is a powerful plugin for Unreal Engine 5 that enables advanced cone-shaped tracing fully accessible from Blueprints. Designed for AI vision, enemy detection, stealth mechanics, and gameplay logic, this system simulates a true cone trace using a series of Box Traces, offering both precision and performance.
Whether you're building AI sight, field of view (FOV) checks, line of sight systems, or environmental awareness tools, this plugin gives you full control over tracing logic, filters, and visual feedback — without writing a single line of C++.
🔧 Key Features
🔹 Cone-Shaped Tracing using iterative BoxTrace logic
🔹 Configurable angle, length, step size, box depth, and tolerance
🔹 Multi-Hit and Single-Hit modes — just like LineTrace or SphereTrace
🔹 Filter by Actor Class, Tags, or Interfaces
🔹 Optional self-ignore and actor ignore list
🔹 Detailed debug visualization: boxes, hit points, direction lines, and radius arcs
🔹 100% Blueprint-compatible — works in pure Blueprint projects
🔹 Built-in Actor Component for interval-based tracing (no Tick required)
🔹 Includes Blueprint Function Library with helper utilities
🔹 Supports usage in AI, Triggers, UI, and Blueprint Scripts
🔹 Use cases: enemy detection, vision cones, FOV scanning, perception checks, cone overlaps, custom collision
