Hi @mhauskn ! According to the manual, feature 6 in high-level state feature list is "Goal Center Proximity - Agent’s proximity to the center of the goal". Here are some values of this feature I got in practice

array([ 0.09794438,  0.06624234,  0.03432488,  0.00357747, -0.02914906,
       -0.05965102, -0.09055936, -0.12043804, -0.14975351, -0.17937934],
      dtype=float32)

According to my understanding (which might be wrong), "proximity" features should have non-negative value. Could you please tell me how these "proximity" features are computed? Or tell me where I can find the code for generating these state features? Thank you very much!
