kindly help me out .
You need to show the code…
in addition to the code (blueprint logic) it would also be useful to get a screencap of your timeline curve.
here you go.
Based on what you have shown here, and assuming these doors are meant to slide apart to open, my guess is either your values (left/right old/new) are being set wrong, or your accidentally mixing relative and world position stuff. Where do you set your vector position values for the old/new stuff?
