I feel like something wrong with agent's observations

[c0mb1ne]

I was inspecting what kind of observations agents gets, and found that in this line of code, we trying to normalize the number remaining enemies to add them to observation. And this variable never being used in this code anymore.

ml-agents-dodgeball-env/Assets/Dodgeball/Scripts/DodgeBallAgent.cs

Line 305 in b2915bd

var portionOfEnemiesRemaining = (float)numEnemiesRemaining / (float)opponentsList.Count;

but here we just add the flat number of remaining enemies, which is kinda goes against ml-agents guidelines about normalizing observation for better perfomance.

ml-agents-dodgeball-env/Assets/Dodgeball/Scripts/DodgeBallAgent.cs

Line 314 in b2915bd

sensor.AddObservation(numEnemiesRemaining);
