Without tick
Interpolation works by sampling previous results: no previous result = no next result. If you do not need this updated every frame, you could use a timer and update it less frequently. Or lower the Tick rate.
I’ve tried with Timelines,by multiplying timeline with the difference between start and end points but then the speed would vary by distance
If you want this time based, you can adjust the timeline’s play rate.
Here’s what I mean:
The only variable here is the distance (displayed) to travel. They move with the same speed, it just takes longer to move further.
