> getting the **Move Component To** to work inside the **For Each Loop**

One cannot combine loops with latent nodes - note the clock icon on the `MoveComponenTo`.

My `MoveTo` is a custom event that lives inside another target actor (since each box was supposed be an actor, as in the original description I tried to adapt to - not guilty ;p ); meaning each actor has an instance of `MoveComponentTo’ which, once fired, can live its own independent life detached from what the loop is doing.

If you’re **not** working with box **actors** :

## Option 1:

- extend the `Static Mesh Component`:

You’ll end up with a static mesh component that can handle a mesh asset, but can **also** host script and variables. I can’t stress enough how convenient this can be at times, and how well it keeps things low profile.

## Option 2:

Instead of trying to Move while the loop is looping, let the loop finish and add everything to a neat map as you do. When the loop has completed, fire a Timeline or Move Component To. But then you’ll need to handle data differently. Here’s an example:

> You could also get a bit cheeky and use a vector for the Alpha value and split it, giving you the opportunity to move multiple objects simultaneously using just a single vector track: [[Image from Gyazo]](https://gyazo.com/c6e2b0cac670a0012d4f392a08f3b514) With each track you can control up to 3 additional elements. You could even combine this method with the re-usability suggestion from my first post but then it might be hard to read and debug. Still, beats 10 timelines. Good luck!

Ignore the track being a vector, you’d use a 0-1 float as alpha. Another 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.

Top bit prepares the data first, then a timeline moves multiple elements of an array.

There’s probably Option 3 & 4 out there that eludes me. Do tell how it goes. I’ll be around later this week.
