I am interested in 2 things on how this works. If I train a brain to do a simple task like pick up object or something and finish and then decide to add actions to that same brain and train it again does it still know what it learned since last time? Can i for example teach it to pick up, ok finish, then add eat and then add mining etc to improve it. Or better yet teach it each of those individually in environments designed to those specific tasks and then merge them all together? Also if I make a game with something like this and people play my game, will the final trained brain keep on learning when the game is being played or will the brain just keep its functionality that it got at the end of the training I did for it while in the unity editor?
