When should I use isMine vs amOwner? These are both values I can ask for from a PhotonView. For context my game is sort of like chess with bullets. Each player owns his own chess pieces and any bullets that his own pieces shoot.
You may be interested in the Creator of pieces/bullet (who instantiated them). If the creator of a networked object leaves, the control will go to the Master Client but the creator is unchanged.
The simulation of each piece/bullet must run on some client, which is why control changes and isMine with that.
amOwner should not change.
