I want to interpolate a value over a set time and not use a speed. I cannot use a timeline as I do not have access to it. Is this possible?
Basically I want something to move from its start position, to its target position over 2 seconds.
Why can’t you use a timeline in the actor class of the component you want to move?

The class is a “StaticMesh” override class so I do not think I can use timelines in that. This is for a sliding door on a van.
He meant a TL in the underlying class owning the component; which would work more than OK for 1 door. Setting up multiple door opening / closing simultaneously, would be a tad trickier.
tl;dr: since vans generally have 1 sliding door, I’d use a TL in the car actor and move on… Other than that, read on.
Consider using a Timer:
Pros
- you can choose how fast they fire
- decoupled from framerate by default
- Tick can sample elapsed time (and / or incorporate delta time)
- use their elapsed / remaning time as Lerp alpha
- can be (un)paused
- you can incorporate a curve to mimic that of a TL
- unlike a TL, it can live inside a component
Cons:
- not as neat as a TL and you must script the entire behaviour
Probably much lighter on resources than a timeline component. Probably.

Adding to this, now that I know its a vehicle…
If the vehicle is a skeletal mesh, rig it and use an animation to move the door.
