Unreal Engine 5 Masterclass: Proximity & Interaction Interfaces (UE5 Tutorial)
Master the art of interaction in Unreal Engine 5!
In this comprehensive 55-minute masterclass, we move beyond basic tutorials to build a professional-grade interaction system from scratch. Whether you're a beginner or looking to clean up your project's architecture, this video covers the two most essential methods for world interaction: Automatic Proximity Sensors and Manual Blueprint Interfaces.
We’ll build a sliding door that uses a "smart" sensor logic to handle multiple players, and then we’ll dive deep into Blueprint Interfaces to create a rotating door and a light switch that share the exact same interaction code.
🚀 What You’ll Learn:
The ProximityBox: Setting up a sensor-based sliding door.
Multi-Player Logic: Using the "Length is greater than 0" check to prevent doors from closing on players.
Blueprint Interfaces: Why they are the "Gold Standard" for professional game dev.
Enhanced Input: Setting up a dedicated Interaction key.
Line Trace Interaction: Precision interaction for rotating doors and switches.
Code Reusability: Using one interface for both a rotating door and a light switch.
Timelines & Lerps: Creating smooth, frame-rate independent animations.
