Laser Interaction Kit is a powerful and flexible laser system plugin for Unreal Engine — designed for creators building puzzle games, sci-fi interactions, or dynamic gameplay mechanics based on laser beams.
With support for real-time reflections, physics-based interactions, and fully customizable behaviors, this plugin allows you to set up complex laser-based logic using just Blueprints — no C++ required.
Emitter, Reflector, and Pushable components form the core of the system, letting you fire, bounce, and apply forces with precision.
Optional components like LaserOrigin, LaserDirection, and LaserForceTarget give you fine-grained control over how and where the beam originates, travels, and interacts.
Built on optimized Line Trace logic, the laser detects overlaps, stops on blocking hits, and can notify any object it touches — frame by frame. Supports split beams, custom reflection angles, and event-based or time-based mechanics, ideal for triggering doors, buttons, energy transfer systems, and more.
The system also supports laser reflection loops without crashes or infinite recursion issues, ensuring stable and predictable behavior even in complex setups.
Easily integrate with external systems thanks to per-frame laser hit events containing detailed collision data.
Whether you're designing complex puzzles or building reactive environments, Laser Interaction Kit gives you the tools to make your gameplay shine.
