Core Interaction System is a free, component-based plugin that makes creating gameplay interactions in Unreal Engine simple and consistent. Just add a ReceiverComponent to your actor and fill any of its 10 slots (events) with actions (functions) you’d like to perform. Then, use the provided Trigger actors—already equipped with a TriggerComponent—to activate these actions through basic Unreal Engine events. This unified approach ensures beginners and experienced developers alike can quickly build rich, responsive interactions without getting bogged down in complexity

Why Use This Plugin?

Core Interaction System is essential for developers aiming to add depth and responsiveness to their game mechanics. It’s ideal for genres like platformers, shooters, adventure games, or any project requiring dynamic actor interactions. Save time, reduce complexity, and focus on building your game’s experience.

⚠️ Note: The Rhythm Trigger is experimental and was designed to handle complex, time-based interactions. It can be used with or without sound for sequencing events but is still being refined for broader use cases. We value community feedback and will continue improving!
