Hello, can i add inputs into timeline to use them inside for the curve?

You cannot. What you can do instead:

- either keep the timeline track as 0-1 alpha and Lerp data
- or load the timeline with predefined curves - this can be done dynamically, too but the curves themselves cannot be modified run-time in BPs unless I missed an update that exposed that

Other than that, we’d need more info regarding what’s the end goal. If it’s for turret rotation patrol thing, Lerp could work OK.

Also, turrent rotation with relative clamps:

The yellow arrow indicates the turret’s front. Oh, and a TL is probably not the way to go about it unless you’re after something truly specific / unique / inflexible. Does not mesh well with target tracking in my head.

And how to get it to work with Pawn Sensing at the bottom of the thread. This should be, ideally, on Tick. Timeline may be too rigid - lots of work to make it _seem_ nice.
