Timeline nodes are special nodes within Blueprints that provide time-based animation to be quickly designed and played back based on events, floats,vectors, or colors that can be triggered at keyframes along the timeline.
Timelines can be edited directly inside the Blueprint editor by Double-clicking on the Timeline in the Graph tab or in the My Blueprint tab. They are specifically built for handling simple, non-cinematic tasks such as opening doors, altering lights, or performing other time-centric manipulations to Actors within a scene.
