How to make Timeline move relative to the Blueprint object

So I have a blueprint like so. V

And this is the event graph so the bridge moves along the X-axis and moves like a bridge. V

But In my game I have 90 degree corners. And the timeline moves relative to the world. so when I turn a corner to the LEFT and go on my bridge… All it does is move to the right, like so

Can someone help me so that it moves relative to the blueprint not the world?

Use this for relative rotation.


if you can’t use this ,i can give you an example with picture
