Hello. I have created a blueprint that makes the train appear when a trigger box is activated. I want it to move along spline after it appears, but something is not working. Train spawns but wont move.

Connect these.

Also, it’s unclear what `Distance` is used for here.

Connecting node doesnt help. About Distance, its position.

- how do you apply it? Hard to imagine this part seeing how the spawned actors are not even referenced.
- where’s the spline? How do we move the whole thing? How is the `Active Path` reference set?
- what is the value of `Speed`?

Speed is on 0.

Sorry, but i am in unreal for 4 months. Almost everything about blueprints for me is strange. I done it by chatgtp advices cuz its hard to find info in youtube. Youtube shows how to move along spline and thats it. Not how to make it togather with other BP, make stops etc.

Spline is in another blueprint only for spline.

As you can imagine, multiplying by 0 can only go one way…

So where is the rest of the script? How do you actually move the actors? Focus on 1 thing at a time, make them move, worry about stopping later.

Here’s an example:

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.
