Cameras

...

This pattern is a still a stub.

Camera is an abstract game element that decides what is the player's current view to the game world.

Examples

Real-time strategy games allow the players to move the camera across the whole game world but the position of the game elements, and in many cases not even the terrain, is typically not revealed. God games, in contrast, allow players to have a complete view of the area that is being viewed. First-person shooters, as the name implies, usually provide first-person views while racing games often let players choose between first-person views to support spatial immersion and third-person views that allow better overview of the local game world environment.

Tomb Raider series

Battlefield series and later installments of the Fallout series use Killcams,

Super Mario 64 provides an exception to the rule that Cameras are abstract objects that are not explained within the game world: although not affected by events in the game world, the camera, and the cameraman, can be seen in mirrors. Another minor exception is the camera in the party game Monkey Boxing in Super Monkey Ball 2, which can be hit during the celebration scene when one of the monkeys has won the game.

Using the pattern

Cameras are used in games to create both Third-Person Views and God Views, and which of these should be supported is a fundamental choice for using the pattern. Depending on which is supported, Cameras can be differently good at providing Surprises, Tension, and Detective Structures.

There are a number of different types of views Cameras can support. Two generic examples are over the shoulder views, which shows game entities from above slightly to the side, and overhead views, which provide excellent relations to the surroundings but which offers little information about focused game entities since they look direct down on them. Both these can be modified by either linking the movement of the Camera to the movement of game entities or locking the Camera to a position relative to the environment (in effect choosing between a Third Person View and a God View). Some Camera views are specific to Third-Person Views. Chase-cams follows behind game entities as they move to convey the sense of movement while fly-by views lock Camera positions while tracing the movement of a moving game entities (this view can also be provided by First-Person Views). Killcams, which shows Replays of deaths in games, can make use of either of these two options.

Players can also be given a Freedom of Choice to manipulate Camera in several ways: by modify them the positioning slightly, by being able to switch between different Camera modes, or being able to move the Camera freely with certain distances from the entities followed.

The type of Camera is usually closely linked to how Focus Loci and Spatial Immersion are used in the game: games with Avatars useFirst-Person Views or Third-Person Views, while games with Units use God Views. While First-Person Views and Third-Person Views easily support Imperfect Information to players by limiting their control of the Camera, God Views can achieve similar effect by using Fog of War.

Making the decision to allow players to control the Camera include making decision of what Extra-Game Actions related to Cameras should be provided: rotation, zooming and absolute movement for God Views and rotation and zooming movement for First-Person Views and Third-Person Views. This increases players Freedom of Choice and Spatial Immersion (as not only the player can make the Avatar or Unit move in the world but also the Game World move around these) but increases the conflict with Consistent Reality Logic.

Consequences

Cameras provide players with views of Game Worlds, and those that can be manipulated by players allow them a Freedom of Choice in what parts of the Game Worlds they want to focus their attention on. Game State Overviews are supported by Cameras both when they are used for God Views and Third-Person Views since in both cases players can observe Game Worlds with better views than any specific game element (for Third-Person Views a large part of this can be simply to see the entity tracked). The ease of using Cameras, decides in a great extent how much games help players perform Attention Swapping.

In games with Avatars, Cameras are typically limited in such a way that they are always in the center of players' views (but see the Sims series for an exception). This maintains the symmetry between what Avatars and players sees so that Tension and Surprises can be achieved and also to strengthen Spatial Engrossment. In games with Units, Camera movement is often completely free to allow the players to move between different game elements and to force them to make Trade-Offs between which parts of Game Worlds to focus their attention on.

Cameras have a fundamental conflict with Diegetic Consistency since they are incorporeal entities and present players with views that no diegetic entity currently has and possibly never could have.
