Description

The present invention relates to a game program and a game system.

  Conventionally known game programs include a wide variety of genres such as RPG (role playing game), action games, sports games, and puzzle games. Among these many game program genres, there are game programs that aim to simulate the experience of the game world that is structured with the phenomenon of the real world as if it were real. . For example, in a racing game, you can enjoy the feeling as if you are participating in a real race, that is, feel a real sense, by driving the actual vehicle type on the actual circuit course or public road. .

  By the way, in such an old game program, the environmental elements in the game world, for example, the conditions for changing the weather, etc., are in the closed range defined in the program, and have no means of communication with the real world. Naturally, the game program only changes regardless of the environmental elements in the real world, and even if an environmental change such as a weather change is expressed, it is only a pseudo-random change based on an algorithm. It was a hindrance when pursuing a feeling.

Therefore, various techniques for reflecting information on environmental elements in the real world in the game world are disclosed in the following documents, for example.

The game program will be described.

[Parameters in game program]
In many baseball game programs, the player operates the player displayed on the screen, and in the defensive scene, the player selects and throws a ball type / course based on the pitcher data of the character imitating an actual pitcher. In the attack scene, the player performs an operation of swinging the bat as a batter displayed in a batter box on the screen. In these baseball game programs, strength data (pitcher data and fielder data) imitating a real professional baseball team, players, and stadium, and stadium data are recorded in advance, and an arbitrary team desired by the player is selected. There are also many things that play games. In such a baseball game program, in order to reflect the individuality of each player in the game game, data obtained by quantifying the results or abilities of each player is recorded.

FIG. 4 shows player data and stadium data recorded in advance in the baseball game program. FIG. 4A shows player data. Athlete data includes basic data such as back number, player name, defensive position, dominant arm (for example, “right throwing right strike”, etc.), batting power (m), long striking force (l), running force (r), Ability parameters in which the shoulder strength (s) and the defense strength (f) are digitized are recorded.

The striking force (m) is a skill of meat, and the long striking force (l) is a numerical value of the hit ball's elongation when hit, and is a coefficient derived from the player's operation, for example, the position and timing of the bat swing relative to the pitch. A numerical value for determining the direction and trajectory of the hit ball. The running power (r) is a numerical value of the speed as a runner. The higher the running power, the higher the running ability. The shoulder force (s) is a numerical value of the sharpness of the pitching at the time of defensive, and the player's operation, for example, the direction of the pitching direction (operated by the direction key 21 in FIG. 2) and the pitching button (for example, the symbol in FIG. It is a numerical value that determines the sharpness of the pitched ball together with the coefficient derived from the pressing timing of the key 22 (operated with the ○ key). The defensive power (f) reflects the skill of fielding, and the larger this value, the less likely it is to make an error. These correspond to the character parameters.

In the right column of FIG. 4A, three elements “heat resistance”, “rain resistance”, and “star characteristics” are shown. These are parameter correction functions that correct each of the above-described capability parameters according to how much the simulated weather described later deviates from the standard weather. Here, as “standard weather”, for example, “temperature: 25 degrees”, “precipitation: 0 mm”, “sunshine duration: 40 minutes”, “wind power: 0 m / s”.

For example, a player with a turn number “00” and a player name “AA” has a long batting force (l) of “50” in standard weather, but the temperature in simulated weather described later is “30 degrees”. Since the degree of deviation (Δh) is 5 degrees, the long hitting power is corrected to “60” and applied to the game. In this case, the player with the spine number “00” and the player name “AA” is characterized as “a player who is resistant to heat”.

Similarly, the element of “rain resistance” is a parameter correction function that corrects a player's ability parameter in accordance with precipitation. The element of “star characteristics” is a parameter correction function that corrects the ability parameter of the player in accordance with the number of spectators determined in combination by the simulated weather, the time when the game is played, the selected team, the battle record, etc. is there.

FIG. 4B is stadium data indicating basic information of a stadium where a baseball game is virtually played. In this table, for example, the stadium name “A stadium” indicates that the infield is “natural soil” and the outfield is “natural turf”. The “bound coefficient” is a parameterization of the degree of rebound when the hit ball bounces. The larger the number, the higher the degree of rebound. The “friction coefficient” is a parameterization of the speed reduction of the hit ball when the hit ball bounces or rolls. The larger the number, the higher the speed reduction. These correspond to in-game environmental parameters.

“Precipitation correction” is a parameter correction function that corrects each coefficient parameter described above according to how much the simulated weather described later deviates from the standard weather. For example, in the case of “A stadium”, when the precipitation correction of the bound coefficient is “−3Δw” and the precipitation correction of the friction coefficient is “+ 2Δw”, when “precipitation” in the simulated weather is “2 mm”, the corrected The bounce coefficient of “40” is “34” which is the result of adding “−6” obtained by multiplying “−3” and “2” from “40”, and the corrected friction coefficient is “64”. In other words, the environment in the virtual world in the game is affected based on the simulated weather, such as the infield is less likely to bounce according to the amount of precipitation, and the hit ball is more likely to die, which also affects the game itself.

Next, a flow in which the game apparatus terminal acquires weather data representing actual weather via communication means will be described.

[Acquisition of weather data]
FIG. 5 shows a flow in which the game apparatus terminal acquires weather data from the predetermined server 100. Here, the “game device terminal” refers to the device body 1 in which the game program according to the present invention is activated. The “predetermined server” is a server that can be connected through the network 99, and stores various information related to a game in addition to weather data described later.

In the server 100, the weather data of the real area related to the game according to the present invention is sequentially accumulated every unit time (step S101). FIG. 6 schematically shows the state. Here, the hourly weather information (wind direction, wind power, temperature, sunshine, precipitation) for the area name “Osaka” is sequentially accumulated. These weather information may be observed by installing an observation device independently, and information published by a public organization such as the Japan Meteorological Agency may be acquired arbitrarily or periodically.

Returning to FIG. 5, it is determined whether or not a game start signal is received at the game apparatus terminal (step S201). Here, for example, in the case of a baseball game, the game start signal is determined after all selections necessary for starting the game (selection of the number of players, selection of a team to play, selection of a stadium to play, selection of a starting order) are made. A signal generated by pressing a button (for example, the circle key of the symbol key 22) and received by the CPU 31. Unless it is determined that the game start signal has been received (step S201: No), the determination is looped and a standby state is entered. If it is determined that a game start signal has been received (step S201: Yes), the CPU 31 starts connection with the network 99 through the communication interface (step S202), and transmits request data upon confirming communication connection with the server. (Step S203).

Here, the request data includes the location information of the stadium selected in the selection of the stadium to be played among the selections at the start of the game, the accumulated time of the past 6 hours, for example, the past time at the start of the game. Contains data.

When the server receives the request data from the game device terminal (step S102), the server searches for corresponding data from the weather data stored in advance (step S103). For example, when the stadium location information in the request data is “Osaka”, the corresponding data is searched from the corresponding stored data. When the corresponding data is detected, the server transmits the corresponding weather data to the game device terminal to which the request data is transmitted (S104). When the game device terminal receives the corresponding weather data (S204), the game device terminal proceeds to a process of reflecting the weather data in various parameters.

In this example, the server 100 in which actual weather data is accumulated is defined as the data acquisition source. However, the present invention is not limited to this. For example, the specification may be such that weather data possessed by a public organization such as the Japan Meteorological Agency is received. .

[Reflection of weather data in various parameters]
FIG. 7 is a flowchart showing a process of reflecting acquired actual weather data in various parameters.

When the weather data is received, the CPU 31 temporarily stores the weather data in a predetermined area of the HDD 34 (step S601). Next, the CPU 31 determines the weather in the game world (hereinafter referred to as “pseudo-weather”) using a behavior model that autonomously determines weather changes according to the passage of time in the game. The process of determining the simulated weather is performed based on a subroutine shown in FIG.

FIG. 8 is a flowchart showing the process of determining the simulated weather.

First, the CPU 31 reads a behavior model from the DVD / CD-ROM 4 on which the game program is recorded, and stores it in the RAM 33 (step S701). Here, the behavior model is based on information on the average and average values of past weather transitions for each region and date and time, and on the subsequent time course based on actual weather data acquired from the server via the communication interface 15. It consists of a model that determines the change of simulated weather. The model that determines the change in simulated weather is expressed by the following equation.
C _t = f (R _t , AVG) Equation 1
Here, C _t indicates simulated weather at the date and time that the acquired weather data has. R _t indicates actual weather data at the time. AVG indicates normal value data. That is, the simulated weather is determined as a function of actual weather data and normal value data.

[Reflect data every hour]
The CPU 31 reads out the weather data acquired from the server via the network 99 from the HDD and takes it into the RAM (S702). As described above, the weather data is digitized data for each time unit. Therefore, the difference between the normal value data and the data at the same time is measured (S703). For example, an hourly divergence state between the weather data about the temperature and the normal value data is measured.

FIG. 9 conceptually shows the weather data regarding the temperature for measuring the deviation from the normal value data. For example, when the game is started at 14:00 at the stadium location “Osaka”, as described above with reference to FIG. 5, as described above with reference to FIG. 5, the weather data retroactive for a predetermined time is acquired from the server and stored in a predetermined area of the HDD 34. Is read into a predetermined area of the RAM 33 as a work area in order to measure the deviation of the normal value data for each weather element. Similarly, after reading the normal value data of the same month from the DVD / CD-ROM 4 into the RAM 33, the deviation value is measured.

Based on the measured deviation value, simulated weather after the game start time is determined (S704). For example, when the temperature is higher than the normal value, the temperature change obtained by shifting the normal value data by the deviation is determined for each time. As shown in FIG. 9, since the deviation value is +2.5, the temperature transition of the simulated weather thereafter is a value obtained by shifting the normal value data by the deviation.

[Determining simulated weather after next day]
Depending on the type of game, the time transition in the virtual world in the game may span multiple days. In that case, it is necessary to determine the simulated weather after the next day. Also in the baseball game program in the present embodiment, when a plurality of games in the pennant race are continuously performed, the time transition in the virtual world in the game extends over a plurality of days. Based on the leveling coefficient, the CPU 31 determines simulated weather for each hour after the next day (step S705). The following formula is used as a formula for determining the simulated weather.
C _{t + 1} = k ^d R _t + (1−k ^d ) AVG Equation 2
Here, C _{t + 1} means simulated weather the day after the data acquisition date in the virtual world in the game. K is an arbitrary coefficient of 0 <k <1. Further, d is a numerical value obtained by counting the number of days from the weather data acquisition date.

[With time correction]
According to the behavior model, it is possible to realize the normal weather transition in the game world while reflecting the first acquired weather data. On the other hand, in order to reflect actual weather data on a regular basis, for example, simulated weather determination means represented by the following equation can be considered.
C _t = f (R _t−1 , R _t , AVG, d) Equation 3
Here, C _t represents simulated weather data at a certain point in time, R _t−1 is the weather data at the time of acquiring the previous weather data, R _t is the weather data at the time of acquisition this time, AVG Is normal value data, and d is the number of virtual days in the game world since the initial weather data acquisition (the first day is d = 1).

In particular,
When d = 1
C _t = k ^d−1 R _t + (1−k ^d−1 ) AVG
When d ≧ 2,
_Ct = kd ^- _1Rt + (1-kd ^-1 ) {kd ^- _2Rt-1 + (1-kd ^-2 ) AVG}
(Where k is an arbitrary coefficient of 0 <k <1) Equation 4
This determines the simulated weather. The simulated weather data determined by Equation 4 is based on the normal value data and can reflect the actual weather data of the past in the past. It is possible to determine the simulated weather while suppressing the above.

[Reflection of simulated weather data to various parameters]
Returning to FIG. 7, the CPU 31 reads various parameters recorded on the DVD / CD-ROM 4 into the RAM 33 (step S603). Here, the various parameters refer to background image parameters, environmental parameters, and character parameters. For example, in the case of a baseball game, the batting power (m) representing the ability of each player of the team selected by the player, long batting power (l), running This is a numerical value unique to each character such as strength (r), shoulder strength (s), defensive strength (f), or a numerical value of the quality of the soil / turf of the stadium selected by the player.

Subsequently, the CPU 31 calculates correction parameters for various parameters based on the various parameter correction functions (S604). For example, in FIG. 4 (a), the player with the team name X with the spine number “00” and the player name “AA” has a heat resistance parameter correction function. As described above, since the temperature of the pseudo weather is 32 degrees which is the same as the temperature obtained from the server at the start of the game (that is, the actual), the temperature is 25 degrees in the standard weather. The divergence is 7 degrees, and the long striking power (l) of the player name “AA” is corrected to “14” plus “64”. Similarly, the parameters of the ball field data are corrected based on the parameter correction function unique to each ball field.

In addition, the wind force and wind direction data can be reproduced in the game by storing in the RAM 33 mainly as a coefficient for correcting the trajectory of the flying ball. For example, depending on the wind direction and the wind force, A parameter correction function may be included in the player ability data so that the bending state of the pitcher's changing ball changes.

The environmental parameters and character parameters corrected as described above are stored in a reference work area in the RAM 33 that is referred to during game play. As a result, the simulated weather is reflected in the personality of the character and the characteristics of the stadium in the game game.

Next, the CPU 31 corrects the background image data with the background image correction function in order to reflect the simulated weather data in the background image (step S606).

FIG. 10 conceptually shows the correction coefficient when the background image data is corrected based on the simulated weather data. As elements of image correction in the present embodiment, three elements of cloud arrangement, sky brightness, and flag display degree are listed. Actually, the present invention is not limited to this, and it is also possible to express on the screen the wetness of the ground according to, for example, the amount of precipitation and the behavior of dust according to the wind.

For example, in the case of standard weather conditions (wind power 0, temperature 25 degrees, sunshine 40 minutes, precipitation 0 mm), the cloud display degree is “30”, the brightness is “80”, and the flag display degree is “0”. These correspond to the default background image parameters. Therefore, the CPU 31 issues a background image generation signal to the graphic processing unit 36 based on these values.

FIG. 11A shows an image corresponding to a standard weather condition. Based on the information of the cloud display degree “30” issued by the CPU 31, the graphic processing unit 36 generates a cloud object 51 a and displays it in the sky area 52 a in the display screen 41. Further, the brightness and color tone of the sky region 52a are controlled based on the brightness “80” information emitted from the CPU 31. And about the flag object 53a, the state which is not fluttering is displayed according to the information of flag display degree "0" emitted from CPU31 similarly.

On the other hand, FIG. 11B shows an image generated based on the simulated weather at the stadium location “Osaka” and time “14:00”. In this case, the cloud display degree is “0”, the brightness is “100”, and the flag display degree is “3”, and an image display reflecting these coefficients is realized.

Specifically, the graphic processing unit 36 does not generate a cloud object based on the information of the cloud display degree “0”. The brightness and color tone of the sky region 52b are controlled based on the information on the brightness “100” emitted from the CPU 31, and are controlled so as to display the color of the sky that is lighter than that in the standard weather condition. Further, based on the information of the flag display level “3”, a state in which the flag object 53b is flying in a considerable amount of wind is displayed.

By reflecting the simulated weather in the background image in this way, the player can visually recognize the simulated weather situation in the virtual world in the game.

Thus, after reflecting the weather data on the game world, the player starts the actual game.

Then, the CPU 31 watches whether a predetermined time, for example, 1 hour has elapsed in the virtual world in the game (step S607). As a time measurement method for the predetermined time in the virtual world, in addition to the time measurement based on the integration of the clock signal in the CPU 31, for example, as the time measurement method according to the operation of the player, the passage of time can be simulated according to the integration of the number of pitches. .

When it is determined that the predetermined time has elapsed (step S607: Yes), the CPU 31 performs a process of updating the simulated weather data (step S608).

Specifically, the simulated weather data of the next time block, here “15:00”, is stored in a predetermined area of the RAM 33 in accordance with the simulated weather (S704) described above with reference to FIG. Thereafter, the process returns to step S603, and correction parameter calculation is performed again. The correction parameter calculated again according to the above-described flow is overwritten on the reference work area in the RAM 33 described above. Thereby, the change of the background image according to the time passage in the virtual world in the game, the change of the ground state, and the change of the ability value according to the individuality of each character are realized in the game game.

As described above, according to the game program according to the present embodiment, it is possible to realize an autonomous weather change while reflecting the actual weather data in the game, and thus it is possible to further improve the realism. , Which leads to improvement of interest.

In this embodiment, the baseball game is taken up. However, the present invention is not limited to this, and can be applied as long as it is a game related to the weather. For example, in the case of a racing game, the reality can be pursued by providing a correlation between the sunshine time and the road surface temperature, and the precipitation and the road surface state. Also, with RPG, it is possible to experience the link with the real world by reflecting the weather conditions in the battle area in the background image, or configuring weapons and attack means that cannot be used depending on the wind and precipitation conditions. it can.

In general RPG, the game world often has unique map information different from the actual map, but even in that case, the simulated weather in a predetermined area in the game world By configuring so as to be calculated based on weather data in a specific area in the real world, it is possible to indirectly experience reality.

In this embodiment, the game program executed in the home game machine has been described as an example. However, the present invention is not limited to this and can be applied to a game program executed in the electronic computer. Furthermore, the present invention can be applied to a game program executed on an arcade game machine.
