Hi, I’m trying to avoid having all my created objects in the same file I want to use these objects in. I have a file called “FlowFields” and in another file, I have a “Particle” object that I want to use in my FlowFields file. I tried just instantiating the object normally like:

```auto
Particle particle = new Particle();

```

This only works if I have the code for the object inside of the main file FlowFields. For the record, both of these files exist in the same folder on my computer.

Help appreciated!

Thanks.

Just hit this button, create a new file (tab) and start to write your class code inside :

Well that’s a bit embarrassing. I swear I did that in my last project and it didn’t work…

Either way, thank you! It worked this time as intended.
