🚪 In this episode, we take our first step toward building a complete Interaction System by learning how to interact with doors in Unreal Engine 5! Whether you’re making a survival horror game like Resident Evil, an immersive RPG, or any interactive experience, door interactions are a core mechanic that adds realism and depth.
We’ll cover triggers, Blueprints, animations, and logic to smoothly open and close doors. This is just the beginning—soon, we’ll expand this system for more complex interactions!
🔹 Topics Covered:
✔️ Creating Door Interactions in UE5
✔️ Setting Up Trigger Volumes for Player Detection
✔️ Handling Door Animations & Transitions
✔️ Blueprint Logic for Smooth Opening & Closing
✔️ Preparing for a Full Interaction System
