TwistedBytes Interaction System is a plugin for Unreal Engine that aims to solve a seemingly simple task - which is interactions. However, complexity grows quickly when trying to implement interaction gameplay mechanics that should support:

  • Playing animations in-sync on multiple skeletal meshes (e.g. first-person and third person player models).
  • Trigger events before, during, and after interactions, e.g. SFX, VFX, custom function calls, etc.
  • Trigger events on specific animation montage frames.
  • Multiplayer scenarios with client-prediction for lag-free user experiences.
  • Proximity interactions.
  • Cursor interaction for Top-Down games.
  • Custom tracing for passive and active abilities.

Basic knowledge in Blueprints is all you need to make use of this plugin. It is built on top of the Gameplay Ability System (GAS) which is heavily battle-tested in popular games like Fortnite and Paragon. The plugin can be easily extended either using Blueprints or C++ as it is designed to be a solid framework for any type of gameplay interactions.
