In fact, they can only be placed inside Actors: that&rsquo;s because, under the hood, what we are really handling when dealing with Timelines are <strong>Timeline Components</strong>, and a component can exist only as part of an Actor who has such component attached to itself. Anyway, the ability to define a blueprint piece of code that runs in a specified time and produces certain results according to a user-provided interpolation value is very useful and being restricted to define all our timelines in the Actor blueprint class is a pity. Fortunately, Unreal Engine provides plenty of tools for implementing such functionality anywhere in our blueprint code, but that requires some C++ coding to build.</p>
