Description

  The present invention relates to a radar screen display method in an air battle game machine.

While the player sits in the seat that imitates the cockpit, while referring to the instruments installed in front of the seat and the display of instruments and indicators displayed on the monitor placed in front of the player along with the scene outside the aircraft, Air battle games that shoot down enemy aircraft have been widely popular.
There are a lot of various instruments and display devices in the cockpit of an actual fighter, but even in the air combat game machine that simulates this, the inside of the cockpit of an actual fighter is faithfully reproduced and the front In addition to the video of your own machine (referred to as “subject” in this application) and enemy aircraft (referred to as “object” in this application) on the monitor screen, the radar screen is displayed to increase the realism of the game. Yes.
For example, the following can be mentioned.

Japanese Patent Application No. 2002-279144

The radar screen display method in this case is the X- and Z-axis top view (ground projection, ie, looking down from above the subject or object as a means to display the mutual positional relationship between the subject and the object. ) Is used.
This display method is sufficient to capture the front / rear / left / right positional relationship centered on the subject, but in the aerial battle game, it is also necessary to grasp the vertical relationship with the object, which hinders game play. .
In other words, if you don't know whether the target object is above or below the subject, you can't attack, and conversely, it is very difficult to avoid it when you are likely to be attacked. there were.

  The present invention has been made to solve the above-described problems, and the object of the present invention is to provide a radar that can easily grasp not only the front / rear / right / left positional relationship of the object with respect to the subject but also the vertical relationship during game play. It is to provide a screen display method.

The above purpose is
In the radar screen display method in an air combat game machine that displays the mutual positional relationship in the ground projection map of the subject and the object using the figure of the subject and the object,
Calculating the altitude difference of the object relative to the subject;
A step of scaling the object graphic according to the height difference;
Displaying the object graphic together with the subject graphic on the radar screen based on the result of the scaling operation;
This can be achieved by the radar screen display method in the above-described air battle game machine.
In this case, when the height of the subject and the object is substantially equal, the object graphic is displayed at the standard size, and when the height of the object is higher, the object graphic is enlarged and displayed according to the height difference. When the altitude is higher, it is recommended to reduce the object graphic according to the altitude difference.
Furthermore, it is also recommended that the object graphic be displayed with a color different from the subject graphic and with low luminance.

With the configuration as described above, it is possible to easily grasp the vertical relationship with the subject and the degree of altitude difference according to the size of the object graphic on the radar screen, so only the front-rear and left-right positional relationships could be determined. Compared with the conventional display method, the game play can be performed very smoothly.
In other words, for example, when an object approaches with a height difference from the front direction of the subject, it is possible to easily grasp whether the direction to be watched by the player is the front side or the upper side or the lower side. Thus, the interest of the game is further improved.
Further, by displaying the object graphic in a color different from that of the subject graphic and with low luminance, the object and the subject can be easily distinguished.

  The best mode for carrying out the present invention will be described below with reference to the embodiments shown in the drawings.

FIG. 1 is a schematic flow chart for explaining a method according to the present invention.
FIG. 2 is an explanatory view showing an example of a display image of the entire monitor screen partially including a radar screen displayed by the method according to the present invention.
FIG. 3 is an explanatory diagram showing a display form according to the present invention of a radar screen when the object is located higher than the subject.
FIG. 4 is an explanatory diagram showing a display form according to the present invention of a radar screen when the object is substantially at the same height as the subject.
FIG. 5 is an explanatory diagram showing a display form according to the present invention of a radar screen when the object is at a position lower than the subject,
FIG. 6 is an explanatory diagram showing a display form according to the present invention of a radar screen when an object at a lower position than an object and an object at a higher position exist simultaneously.

  As shown in FIG. 2, on the monitor screen 1 of the air battle game machine, a radar screen 11 is simultaneously displayed in addition to an image 12 in which the object (own machine) is viewed from the outside. Furthermore, depending on the progress of the game, an image that looks like the outside from inside the cockpit is also switched and displayed as appropriate, but even in that case, the radar screen 11 is displayed at the lower left of the monitor screen 1 and the subject and The positional relationship between objects is displayed in a concentric circle area centered on the subject.

  That is, in the radar screen 11, as shown in FIGS. 3 to 6, the subject figure S is displayed at the substantially central portion thereof, and the figure O of the object flying within the effective range of the radar is displayed. Are displayed as concentric circles indicating the distance of the distance, and a range of angles in which the subject can travel as a straight line that forms a sector.

The radar screen display method according to the present invention will be described with reference to FIG.
As shown in FIG. 1, when the display of the radar screen is started, an altitude difference HD between the altitude HS of the subject and the altitude HO of the object existing within the effective range of the radar is calculated based on the game program by the formula HD = HO. -Calculated by HS.
After that, the value of the height difference HD is compared with 0 (zero). When HD> 0 (that is, when the object is higher than the subject), when HD = 0 (that is, when the object is the subject) And a case where HD <0 (that is, when the object is at a position lower than the subject) and display different radar screens.

  First, when HD> 0, that is, when the object is at a position higher than the subject, an image processing operation is performed to enlarge the object graphic in accordance with the absolute value of HD, and based on the output, FIG. As shown, the object figure O is displayed larger than the subject figure S. As described above, the size is displayed larger as the absolute value of HD is larger. At this time, the color of the subject graphic S is displayed in blue, for example, and the object graphic O is displayed in yellow and at a lower luminance than the subject graphic S. By doing so, it becomes easy to distinguish between a subject and an object.

  Next, when HD = 0, that is, when the object is almost at the same height as the subject, the standard value of the size of the object figure is output, and based on the output, as shown in FIG. The object graphic O is displayed in yellow with low luminance and the same standard size as the subject graphic S.

  Next, when HD <0, that is, when the object is at a position lower than the subject, an image processing operation is performed so as to reduce the object figure in accordance with the absolute value of HD. As shown in FIG. 5, the object graphic O is displayed smaller than the subject graphic S. As described above, the size is displayed smaller as the absolute value of HD is larger. Similarly to the above, the object graphic O is displayed in yellow and with a lower luminance than the subject graphic S.

FIG. 6 shows a display form when two objects are simultaneously present at different altitudes within the effective range of the radar.
The figure Oa of the object flying at a position lower than the subject is smaller than the subject figure S and is displayed in yellow with low luminance.
On the other hand, the figure Ob of the object flying at a position higher than the subject is displayed in a green color that is larger than the subject figure S and has a low luminance (to facilitate the distinction from the yellow object figure Oa).

  In this way, the difference between the subject and the object is displayed by the difference in color and brightness, and the vertical relationship and distance of the object with respect to the subject are displayed by the difference in the size of the object graphic, so that the player can display the radar screen. With reference to the above, it is possible to perform an appropriate game operation.

  The control for executing the radar screen display method according to the present invention as described above in accordance with the flowchart schematically shown in FIG. 1 is performed by a predetermined computer program (described above) incorporated in the hardware provided in the air combat game machine. This is realized by executing a program including processing according to the flowchart using the hardware.

  The present invention is not limited to the above-described embodiments, and includes all modified embodiments that can be easily conceived by those skilled in the art from the above description within the scope of the object.

  The present invention is configured as described above, and since it is possible to easily grasp the vertical relationship with the subject and the degree of altitude difference depending on the size of the object graphic on the radar screen, only the front-rear and left-right positional relationships can be determined. Compared with the conventional display method, the game play can be performed very smoothly, which contributes to the development of the game machine industry.
