Question about mlagents .addObservation()

[whole idol]

I'm playing around with mlagents for the first time, and had a question about the way observations work. The screenshot is how I implemented adding observations, and I'm curious if its the better, worse, or the same as just adding an observation for each individual value.

Theres no errors or anything, I just want to know if I should put all the related data in an array before feeding it in like I did, or if it doesnt matter. The program does this for up to 30 different objects, so a total of 90 observations
any help or advice is appreciated (specifically about how observations work with ml agents)

if you look at the AddObservation method you'll see it's just calling the same method for each type so they're all doing the same thing in the end

@whole idol You can add arrays, or a number of other types, using AddObservation(). You can see the overloads for AddObservation() here: https://github.com/Unity-Technologies/ml-agents/blob/f442194297f878a84eb60c04eccf7662cbc9ff60/com.unity.ml-agents/Runtime/Sensors/VectorSensor.cs#L137

ok thanks! Thats mostly what I figured. I wasn't sure if sending an array through add Observation somehow linked those observations together as being "related" or something. But if each observation is just an input in a NN model, it makes sense that it doesn't really matter.
