Game machine, performance control method, and performance control program

Abstract

A game machine, a performance control method, and a performance control program that make it possible by simple processing to identify the distance between a three-dimensional object and a virtual camera and the point of view of the virtual camera, and make it possible to provide a highly amusing game by means of player's operations on the virtual camera. Map information constituted by at least one section and layer information having a plurality of layers set for each section of the map information are stored. A performance object which specifies a performance mode in a game using a game medium is placed in at least one of the layers in at least one of the sections. When a section change operation for changing a section is accepted and a layer change operation for changing a layer in each section is accepted, a performance in the performance mode specified by the performance object is provided if the section is changed by the section change operation to the section that has the layer where the performance object is placed, and the layer is changed by the layer change operation to where the performance object is placed.

1 . A game machine, comprising:
 a map information storing device configured to store map information that is constituted by at least one section;   a layer information storing device configured to store layer information that has a plurality of layers set for the section of the map information stored in the map information storing device, a performance object being placed in at least one of the layers in the at least one section, the performance object specifying a performance mode in a game using a game medium;   a layer change operation accepting device configured to accept a layer change operation for changing a layer of the section to be displayed on a display device among the layers that are set for the section by the layer information stored in the layer information storing device; and   a performance device configured to provide a performance in the performance mode specified by the performance object when the layer is changed to where the performance object is placed, by the layer change operation accepted by the layer change operation accepting device.   
     
     
         2 . The game machine according to  claim 1 , further comprising section a change operation accepting device configured to accept a section change operation for changing the section to be displayed on the display device among the sections constituting the map information, and wherein
 the performance device is configured to provide a performance in the performance mode specified by the performance object when the section is changed to the section that has the layer where the performance object is placed, by the section change operation accepted by the section change operation accepting device, and the layer is changed to where the performance object is placed, by the layer change operation.   
     
     
         3 . The game machine according to  claim 2 , comprising:
 a distance measuring device configured to measure a distance between the section before the section change operation of the section change operation accepting device and the section that has the layer where the performance object is placed; and   a layer change operation device configured to enable the layer change operation of the layer change operation accepting device if two sections are decided to be the same from the distance measured by the distance measuring device.   
     
     
         4 . The game machine  claim 1 , further comprising:
 a deciding device configured to decide a result of drawing whether or not to perform a jackpot game in the game; and   a section change control device configured to disable the changing of the section to the section that has the layer where the performance object is placed, by the section change operation accepted by the section change operation accepting device if the decision device decides that the result of drawing is not to perform the jackpot game, and enabling the changing of the section to the other section if the result of drawing is to perform the jackpot game, and wherein   the performance device is configured to provide a performance in the performance mode specified by the performance object if the changing of the section to the other section is enabled by the section change control device, a display range is changed to the other section, and the layer is changed to where the performance object is placed among the layers set for the other section.   
     
     
         5 . A performance control method, comprising:
 storing, by a map information storing device, map information that is constituted by at least one section;   storing, by a layer information storing device, layer information that has a plurality of layers set for the section of the map information stored in the map information storing device, a performance object being placed in at least one of the layers in the at least one section, the performance object specifying a performance mode in a game using a game medium;   accepting, by a layer change operation accepting device, a layer change operation for changing a layer of the section to be displayed on a display device among the layers that are set for the section by the layer information stored in the layer information storing device; and   providing, by a performance device, a performance in the performance mode specified by the performance object when the layer is changed to where the performance object is placed, by the layer change operation accepted by the layer change operation accepting device.   
     
     
         6 . A non-transitory digital storage medium having stored thereon a computer program with a program code for performing, when the program is executed on a computer, a performance control method comprising:
 storing, by a map information storing device, map information that is constituted by at least one section;   storing, by a layer information storing device, layer information that has a plurality of layers set for the section of the map information stored in the map information storing device, a performance object being placed in at least one of the layers in the at least one section, the performance object specifying a performance mode in a game using a game medium;   accepting, by a layer change operation accepting device, a layer change operation for changing a layer of the section to be displayed on a display device among the layers that are set for the section by the layer information stored in the layer information storing device; and   providing, by performance device, a performance in the performance mode specified by the performance object when the layer is changed to where the performance object is placed, by the layer change operation accepted by the layer change operation accepting device.
