  • Patent number: 8398487
    Abstract: Provided is a game device which allows a reduction in processing load relating to the control of player characters belonging to one team, in a case where any one of player characters belonging to another team is in possession of a moving object. A selecting section (52a) selects one or more player characters from among player characters belonging to the team which is not in possession of a moving object. A player character control section (52) controls such that the player character selected by the selecting section (52a) approaches the moving object. In a case where the moving object or the player character in possession of the moving object is located within a restriction region, a restricting section (56) imposes a restriction on the control to be executed by the player character control section (52). A restriction region control section (54a) changes the size of the restriction region based on game situation information.

  • Patent number: 8353748
    Abstract: Provided is a game device capable of allowing a user to designate a position within a region of a game space which is not being displayed on a game screen. If it is judged that a screen coordinate value according to a user's operation is within the game screen showing a state of a first region within the game space, a position-in-first-region acquisition unit (83a) acquires a position within the first region corresponding to the screen coordinate value. If it is judged that the screen coordinate value is not within the game screen, a second display control unit (86b) causes an image showing a state of a second region within the game space to be displayed on a part of the game screen based on a positional relationship between the screen coordinate value and the game screen for at least a predetermined time.

  • Patent number: 8348735
    Abstract: Provided is a game machine allowing a game player to give an instruction to perform predetermined game processing to the game machine and an instruction of the condition of when the predetermined game processing is started. The game machine performs game processing at given time intervals, updates one or more game-related parameters, and causes the update to be reflected on a game screen. A storage unit (50) stores a parameter condition representing the condition of parameters in correspondence with each of a plurality of items of operation information indicating details of an operation for making the game machine execute given game processing. A judging unit (56) judges whether or not the one or more parameters satisfy the parameter condition corresponding to operation information indicating details of a game player's operation.

  • Patent number: 8333663
    Abstract: To provide a game device capable of allowing a user to feel a difference in state of mind between a player of a winning team and a player of a losing team when defending. A selection unit (56) selects one or more player characters from among the player characters belonging to a team not in possession of a moving object. In a case where control by a first player character control unit (58) is applied, a determination unit (62) determines whether or not a reference period has elapsed after a given reference time. In a case where elapse of the predetermined period after the reference time is determined, a switching unit (66) switches the state in which control by the first player character control unit (58) is applied to a state in which control by a second player character control unit (60) is applied. A reference period data control unit (64) changes the length of the reference period, based on game state information.

  • Patent number: 7976371
    Abstract: To provide a game device for producing, in a preferred mode with relatively simple processing, a picture in which a predetermined game event occurs as a result of involvement in multiple contacts. A contact determination unit (74) determines whether or not a predetermined contact condition is satisfied, based on the positions of the contact evaluation target object and the contacting candidate object. A contact evaluation point calculating unit (76) calculates, when it is determined that the predetermined contact condition is satisfied, a contact evaluation point of the contact evaluation target object, based on a state of at least one of the contact evaluation target object and the contacting candidate object in the virtual three dimensional space. A contact evaluation point cumulative value storage unit (78) stores the cumulative value of the contact evaluation point.
