In this video I build an Ultimate Interaction System in Unreal Engine 5 that’s not limited to a single object. The whole point is to give you a proper structure: I set up a Base Interactable blueprint that becomes the parent for every interactable in your game—doors, chests, pickups, anything. I use a simple overlap sphere to know when the player is near, then I run a trace from the center of the viewport to detect what you’re actually looking at, so you don’t accidentally interact with the wrong thing. To keep everything modular, I put the core logic inside an Interaction Component that you add to your character. If you remove the component, the interaction system stops without breaking anything else, which keeps the project clean. I also show how I handle hover/unhover using a Blueprint Interface (so I don’t rely on expensive casting), and I add a 3D tooltip widget (“Press E to interact”) plus optional outline highlight. Finally, I create child blueprints like Door BP and Chest BP and implement their unique interaction logic (timelines, rotation, toggle open/close) while inheriting all the base interaction features automatically.
