Questions tagged [game-physics]

Game Physics is about implementation, creation, optimization and any other thing related to physics in games. Physics controls the interaction of every physical object in a game, where any 2d or 3d model interacts with any other 2d or 3d model of an object in a game. Physics is used to give realistic effects of this interaction.
