Hello! this is a two part question Wondering how to set a starting position of an actor on a spline right now all the actors begin their movement on a spline from the bigging of the spline itself. and if I “push” the actor it will also jus jump to the beginning of the spline and a second question How to make sure the actor “loops” on the spline at this moment the movement ends as soon as actor reaches the end of the spline ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/3/e/c/3ec1e1e99e5d01c1e1ae896f49ac26205b1ccb64.jpeg) ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/2/2/7/227376ba3a5f1e6bd8ae79c1382bfd5d21859a1c.png) Thank you! ---

We can also `Find Location Closest to World Location` with a node - can be convenient at times. > [@SkayKosh](#): > > How to make sure the actor “loops” on the spline at this moment the movement ends as soon as actor reaches the end of the spline Usually with [modulo](https://www.youtube.com/watch?v=HXCkOzkgamU), have a look: > [@Move multiple actors along spline](https://forums.unrealengine.com/t/move-multiple-actors-along-spline/437200/7): > > Here’s a simplified (compared to yours) script I’d use were I to push numerous actors along a spline: [[Image from Gyazo]](https://gyazo.com/cc07a1a805a8c28391c561dbac6e5380) Essentially, each car stores an offset. We animate another spline offset using a timeline, add both, and reposition the car. An optional Modulo wraps the value so we get perpetual motion. But you can also use a `Looping` Timeline’s float track to progress through a spline’s time directly. ---

hi! thank you for the suggestions here is what i have tried I have added find location closes to world location for the actor and used that at the beginning of my “Push” blueprint ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/5/d/1/5d11e9d636c915dc79641e71dddc8114df3676f3.png) ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/8/a/e/8aeedda202d3d3b9ea378ffbf396e797fd29cb9d.png) I tried this before and it didn’t work, the cart actor is still starting its movement from the beginning of the spline Overwise I don’t quite understand where else in the blueprint I need to set the starting actor position (the start vector variable is the start of the push) as far as timeline goes, currently my only timeline is for pushing movement I did attempt what i saw in the example you provided ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/6/0/0/6002cc7aca619db02a49cfccedf9c2379a27cb71.png) but this only works as movement for the entire spline, and not incremental pushing like what I had set up thank you again!

> [@SkayKosh](#): > > and if I “push” the actor it will also jus jump to the beginning of the spline Could you give us a super brief rundown of how it’s supposed to work? Are we pushing a mining cart along a spline? If so, what’s the timeline for? Do we touch it and it goes from point A → B? Or it only moves while we prod it? ---

Timeline is for the carts movement itself here is how timeline looks ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/c/b/5/cb5319263a021856d80611a4286cafe62e1cc5d1.png) and yes the cart only moves when interacted with and currently spline is its own actor and both carts are actors as well
