How do you collect analytic data of a players movements?

Howdy,

I am trying to create a blueprint to collect the analytic data of a players movement, which will later be exported. My goal is to record how a player moves about a scene while performing a specific task and convert it to a graph or 2D document.
The game will be in VR, the actor will be using a VR headset(either Vive or Oculus) and haptic gloves.

Thank you for any help!

If under player movement you mean the location and look angle, why can’t you just store the pawn location and the controller rotation in every frame (or some interval), and save to a file?

Then you can process that file in any external program (depended on what do you actually want to represent with it).

Howdy, Thank you for replying.

That sounds like it would work, do you happen to have a tutorial or would mind telling me the best way to do that?
Sorry, I am slightly a noob when it comes to these things, I am typically the environment artist.

Well it’s not so trivial if you’re not a programmer, as you can’t really write raw text files with Blueprints without a plugin, you generally need C++ knowledge for it. I’d advice getting a programmer for it

I wish I could, but for this specific task I have to do it myself. Thank you though, I appreciate your advice!

Well if you really have to do it yourself, the easiest might be to:

Create a vector array
In Tick(), add a new element to it with the value of GetActorLocation()
You can use Rama’s plugin (or choose another one from Marketplace) to write this array to a text file: (39) Rama's Extra Blueprint Nodes for You as a Plugin, No C++ Required! - Blueprint Visual Scripting - Unreal Engine Forums

Hope it helps!

xRebelKittyx just wondering if you managed something for this. If not, I’d be willing to work with you on this
