If you say that someone is playing at something, you disapprove of the fact that they are doing it casually and not very seriously.
If someone, especially a child, plays at being someone or doing something, they pretend to be that person or do that thing as a game.
If you do not know what someone is playing at, you do not understand what they are doing or what they are trying to achieve.
