Camera Behaviors 49 Cut-scenes, as they are sometimes called, are often used to impart story or game play information that must be guaranteed to be seen by the player at least once. On subsequent viewings, the player is usually allowed to skip the sequence at any point by pressing a button on the controller. Real-time cinematic sequences While somewhat akin to the movie-like experience mentioned above, real-time or in-game cinematic sequences are actually pre-defined game events that play out during regular game play that continue regardless of the player’s actions.
This approach is often used within hybrid first person/third person presentation styles to aid with aiming. Visible feet The camera is positioned away from the character such that animation is still clearly visible, and a good view of the surrounding area is possible. 13b). 13a. Far distance The camera is located far behind the player character; this is greatly dependent upon the environment (since it is usually desirable to avoid occlusion), and is a common solution in vehicle games. The orientation of this camera often lags behind movement of the character to avoid rapid reorientation and to allow the character to be seen as three-dimensional.
However, even the earliest of all video games might be considered as third person despite the fact that the presentation style would likely have been two-dimensional. While this type of presentation is often not quite as immersive as an FP camera (in part due to the unusual nature of seeing oneself from a distance), it does offer a number of advantages. Although there are many variations on the relative position and orientation of the camera compared to the player character, TP cameras are typically able to show the relationship between the player character and the environment quite clearly, allowing for greater interaction in many cases.
