Universal Interaction System (UIS)

A modular, multiplayer-ready interaction system built entirely in Blueprints.

UIS gives Unreal Engine developers a powerful and flexible framework to handle in-game interactions with zero coding. From simple item pickups to complex hold-to-interact mechanics, this plug-and-play system is perfect for any genre.

💡 Key Features:

• Tap & Hold Interactions
  • Swap interaction types at runtime to fit any scenario tap to open, hold to charge, etc.

  Cleanly separate multiplayer logic using dedicated Event Dispatchers:

  • Run UI and local effects on the Client
  • Run world-changing logic (e.g., doors, generators) on the Server

• Debug Tools Included
  • Toggle debug mode to visualize interaction traces in real time.

🎮 Included Examples:

• Item pickup
• Door toggles
• Generator with hold-to-activate
• Outline color variants
