InteractCore — Advanced Interaction Framework for Unreal Engine

InteractCore is a performance-oriented interaction framework for Unreal Engine designed to make complex interaction systems easier to build, scale, and maintain.

It provides efficient proximity detection, aiming, visibility, occlusion, overlap detection, and intelligent target selection through a clean C++ and Blueprint-friendly workflow.

Key Features

• Optimized Detection — Octree-based spatial queries for efficient interaction detection.

• Intelligent Target Selection — Configurable scoring based on distance, aim, screen position, visibility, and occlusion.

• Visibility & Occlusion — Built-in line-of-sight checks and interaction blockers.

• Interaction I/O — Connect actors and create interaction chains without tightly coupling gameplay systems.

• Blueprint & C++ — Designed for both rapid Blueprint workflows and advanced C++ customization.

• Debug & Profiling Tools — Visualize interaction queries, blockers, scores, and performance statistics.

• Scalable Architecture — Built around Unreal Engine Subsystems and spatial partitioning.

From doors, switches, pickups, and NPCs to puzzles, gameplay devices, and complex chained events, InteractCore provides the interaction layer your project needs.

Build your gameplay. Connect your systems. Let InteractCore handle the interaction layer.
