Export variables values over time

[TasKall]

Hi there,

I have created a simple vehicle simulator and I would like to export the values of several variables (speed, position XY, steering angle etc.) - that are already promoted to variables in the blueprint-, over time. In fact, I would like to export a csv file for example that contains 1 column for time evolution and one column for each variable.

Is it possible to achieve this in blueprint and how? If not, what is the best solution?

Hey @TasKall!

It is definitely possible. There are plugins that can already do this on the marketplace like:

easyCSV in Code Plugins - UE Marketplace

and

Runtime DataTable in Code Plugins - UE Marketplace

Also check out this thread post here for reading and writing a text file:

Can i export data table to csv file using Blueprint?

I had this same question a few years ago for a research project. There was an Unreal user who did a tutorial for how to code a C++ plugin to output CSV. It wasn’t too hard: [Unreal Engine 4 Good to Know - Read and Write Text File] Also I think Rama’s Victory plug-in would work - but I also needed a Mac compile. Hope this helps!

I hope the above points you in the direction you are looking for!

Hey @TasKall

Please let us know if one of those solutions works for you!

After contact Jared Therriault, the Runtime DataTable plugin is the one that exports CSV in realtime.
I finally create my BP in order to export the CSV with the parameters values every time interval. The following image shows how.
