Game program and game system

Abstract

To provide a game program which realizes an increase in realism by reflecting actual weather information in a hypothetical world in a game. A CPU of an apparatus main body obtains actual weather data via a communication interface, and stores it in an HDD. Simulated weather is determined based on a behavioral model which includes the weather data and average year value data recorded in advance in a DVD/CD-ROM. Then, based on the simulated weather determined and parameter correction functions recorded in advance in the DVD/CD-ROM, a character parameter and a background image parameter are corrected, and the actual weather is reflected in an image displayed on a display device.

1 . A computer program which is stored in a memory of a computer to: display one or a plurality of characters, including a character which is a player's operation object, on a screen of a display device of the computer; determine behavior of the character which is the player's operation object in accordance with an operation input from an operating module operable by the player; and cause the computer to progress a game on the screen, the program comprising the steps of: 
 obtaining actual weather data via a communication section;    storing the obtained weather data in a memory;    storing in advance in a memory a behavioral model which determines behavior of weather in the game in accordance with a passing of time;    with the obtained weather data as an initial value, determining simulated weather which changes based on the behavioral model; and,    based on the determined simulated weather, correcting at least one of a background image parameter for generating a background image, an environment parameter for setting environment conditions in the game, and a character parameter for setting an individuality of the character.    
   
   
       2 . A computer program which is stored in a memory of a computer to: display one or a plurality of characters, including a character which is a player's operation object, on a screen of a display device of the computer; determine behavior of the character which is the player's operation object in accordance with an operation input from an operating module operable by the player; and cause a computer to progress a game in a computer on the screen, a method of executing the program comprising the steps of: 
 obtaining actual weather data via a communication section at each prescribed time;    storing the obtained weather data obtained in a memory;    storing in advance in a memory a behavioral model which determines behavior of weather in the game in accordance with a passing of time;    based on the weather data obtained over a plurality of times and on the behavioral model, determining a change of the simulated weather; and,    based on the determined simulated weather, correcting at least one of a background image parameter for generating a background image, an environment parameter for setting environment conditions in the game, and a character parameter for setting an individuality of the character.    
   
   
       3 . A computer program according to  claim 1 , wherein 
 the actual weather data is obtained via the communication section from a prescribed server.    
   
   
       4 . A game system comprising: 
 a processing unit;    an operating module operable by a player;    a display device which displays one or a plurality of characters, including a character which is a player's operation object, on a screen; and    a memory which stores a program and a behavioral model which determines behavior of weather in a game in accordance with a passing of time, the program being executed by the processor unit to:    display the character which is the player's operation object in accordance with an operation input from the operating module;    obtain actual weather data accumulated in a prescribed server via a communication section;    store the obtained weather data in a memory;    with the obtained weather data as an initial value, determine simulated weather which changes based on the behavioral model; and,    based on the determined simulated weather, correct at least one of a background image parameter for generating a background image, an environment parameter for setting environment conditions in the game, and a character parameter for setting an individuality of the character.    
   
   
       5 . A game system comprising: 
 a processing unit;    an operating module operable by a player;    a display device which displays one or a plurality of characters, including a character which is a player's operation object, on a screen; and    a memory which stores a program and a behavioral model which determines behavior of weather in a game in accordance with a passing of time, the program being executed by the processing unit to:    display the character which is the player's operation object in accordance with an operation input from the operating module;    obtain actual weather data accumulated in a prescribed server via a communication section at each prescribed time;    store the obtained weather data in a memory;    based on the weather data obtained over a plurality of times and on the behavioral model, determine a change of the simulated weather; and,    based on the determined simulated weather, correct at least one of a background image parameter for generating a background image, an environment parameter for setting environment conditions in the game, and a character parameter for setting an individuality of the character.
