A game control device includes a direction obtaining unit, a motion data selection unit, and a user character control unit. In a case where a direction designating operation is performed by a user, the direction obtaining unit obtains a relative direction of the direction designated through the direction designating operation relative to the forward direction of a user character. The motion data selection unit selects any of motion data correlated to a type to which the relative direction obtained by the direction obtaining unit belongs from among the motion data stored in a unit that stores a type of a relative direction relative to the forward direction of the user character and a plurality of kinds of motion data so as to be correlated to each other. The user character control unit causes the user character to perform a motion in accordance with the selected motion data.

A forward direction line is set on a course, in a virtual game world, on which a player object is allowed to move. An advancing direction at a current position of the player object is determined based on the forward direction line. The advancing direction is determined as a direction in which the player object advances so as to control a movement of a player character in accordance with an acceleration instruction, and a leftward-rightward movement instruction from a player. Consequently, it is possible to assist the player in controlling a direction in which an object operated by the player moves.

A video game device calculates a difference vector extending from a predetermined reference position on the screen to an input position. Moreover, the video game device calculates movement parameter data used for moving, with respect to a fixed point in the virtual space uniquely determined based on a position of the controlled object, the point of sight to a position that is determined by a direction in the virtual space based on a direction of the difference vector and a distance in the virtual space based on a magnitude of the difference vector. The point of sight is moved based on the movement parameter data. The video game device produces an image based on a virtual camera, which has been moved according to the movement of the point of sight, and displays the image on the screen of a display device.

Methods and computer programs for providing animation to online roulette game during game play include providing data for enabling an interface on a device used for playing the online roulette game. The interface renders a grid identifying bet entries and a roulette wheel on which a ball is provided to determine outcome of the roulette game. A number on the grid on which a bet has been placed, is identified. A number is randomly generated to determine outcome of the roulette game. The number corresponds with a specific one of the plurality of slots defined in the roulette wheel in which the ball is to land. Graphical animation is provided at the roulette wheel to provide visual indication of the outcome of the roulette game as the ball is caused to move around the roulette wheel toward the specific slot in the roulette wheel corresponding to the generated number.

A movement direction of an object arranged in a virtual world is set based on attitude data. Further, the object is moved in the movement direction in the virtual world in accordance with data based on a load applied to a load detection device. An image showing the virtual world including at least the object or an image showing the virtual world viewed from the object is displayed as a first image on a portable display device.

An operation target object in a virtual game space as seen from a virtual camera is displayed on a display device. A moving direction of the operation target object in a virtual space in accordance with a direction represented by direction data based on a direction input by the user is determined based on an exactly upward vector representing a direction of a virtual gravity acting on the position of the operation target object in the virtual space and a direction of the normal in the virtual field at the position. The operation target object is moved in the determined moving direction.

A forward direction line is set on a course, in a virtual game world, on which a player object is allowed to move. An advancing direction at a current position of the player object is determined based on the forward direction line. The advancing direction is determined as a direction in which the player object advances so as to control a movement of a player character in accordance with an acceleration instruction, and a leftward-rightward movement instruction from a player. Consequently, it is possible to assist the player in controlling a direction in which an object operated by the player moves.

It is determined, based on attitude data, whether or not a direction of a predetermined axis set in a portable display device is within a first range. When the result of the determination is that the direction of the predetermined axis is within the first range, an action of a first object arranged in a virtual world is controlled based on the direction of the predetermined axis. When it is determined that the direction of the predetermined axis is outside the first range, at least an action of a second object arranged in the virtual world is controlled based on the direction of the predetermined axis. Then, a first image showing the virtual world including at least the first object and the second object is displayed on the portable display device.

A game apparatus displays game space on a display means, and the game space includes a first area and a second area which interrupts continuity of a movement of an object in the first area. A user sets a moving route within the game space by means of a touch pen. The collision, that is, the object moves along the route. Assuming that the object moves to a next point position on the route, when the next point position where the object will enter the second area is set, the computer corrects the next point position to a target position within the first area, and then moves the object thereto.

In order to attain the object described above, a game apparatus is able to use a touch panel 13 and operation means, executes a shooting game, and positions an aim G3 representing a shooting direction at a predetermined position. When sliding operation is received on the touch panel, the aim G3 is displaced from the predetermined position by a moving distance based on change of a touch position (input coordinate position). Shooting is virtually performed in a direction based on the position of the aim according to an operation on the operation means.
