This game system displays a main game image on a main display screen, and displays auxiliary information such as message information transferred from other players on the display means of each operation device.
[0002]
[Problems to be solved by the invention]
The above prior art has the following problems, and it is not possible to give diversity in the way of presenting game images. In particular, when the character moves in the game world, the player does not feel the movement of the game world.
(1) Prior art 1
Since there is only one display means, the game image presented to the player of the game image has no diversity or unexpectedness.
(2) Prior art 2
The information displayed on the display means of the operating device is auxiliary information relating to the game progress, and merely indicates the auxiliary role of the game image displayed on the main display screen.
[0003]
Therefore, the present invention has an object of providing a plurality of display means to give a variety of ways to present a game image, and in particular, when a character moves in the game world, the player feels the movement of the game world. The main purpose is to
Another object of the present invention is to provide a plurality of display means and simultaneously present a plurality of game worlds to increase the interest of the game.
[0004]
The invention of claim 1A game system comprising a first display means, a second display means, and an operation means, wherein the first display image data for causing the first display means to display a partial area of the first game world And a part of the second game world that is different from the first game world and has a corresponding relationship with the first game world is displayed on the second display means. Display image data generating means for generating the second display image data, and further including an image representing the player character in one of the first display image data or the second display image data, Position updating means for updating position data in a memory indicating the position of the player character in the game world in response to an operation; the player character is connected to the first game world and the first game character; State storage means for storing in the memory state data indicating in which game world of the game world, and the player character is one of the first game world and the second game world When it is detected that the movement condition is allowed to move from the world to the other game world, the state update means for changing the state data on the memory is provided, the display image data generation means, Of the first display image data or the second display image data, an image representing a player character is included in the display image data corresponding to the game world indicated by the state data, and the position updating means In response to the update of the position data, the partial area of the first game world displayed on the first display means and the second display means For the partial area of the second game world shown, the corresponding areas of the first game world included in the first display image data are displayed on the respective display means in conjunction with each other. The game system determines a partial area and a partial area of the second game world included in the second display image data.
[0005]
According to the present invention, a different game world is displayed on each display means (the first display world is displayed on the first display means, and the second game world is displayed on the second display means. ). The character operated by the player is displayed on one of the display means (when the character exists in the first game world, it is displayed on the first display means, and when the character exists in the second game world, the first display means is displayed. 2). The character is movable between the first game world and the second game world, and the character is displayed on the first display means or the second display means in accordance with the movement between the game worlds. The player can feel that the character has moved in the game world.
[0006]
In the present invention, the game world is a virtual world in which a game progresses, and is typically a space in which a character can move. In the present invention, there are a plurality of game worlds, and the character can move between the game worlds. Here, the fact that there are a plurality of game worlds means that there are a plurality of game worlds having a certain unity, and it does not mean that each game world is a completely different game world. For example, as described later, it is assumed that the first floor portion and the second floor portion of the maze are different game worlds.
[0007]
When the game processing result satisfies a predetermined condition, the character moves between the first game world and the second game world. Here, the predetermined condition is, for example, when the character operated by the player exists at a predetermined position. Specifically, when a character is present at a specific place (pitfalls, warp points, stairs, jump stand, boarding position of a vehicle, etc.) in the first game world, the character is moved to the second game world. The same applies when moving from the second game world to the first game world. In another example, when an attribute value of a character reaches a predetermined value (or when it exceeds or exceeds a predetermined value), when an event is cleared, or when a player inputs a predetermined command, an item The case where it is used is considered.
[0009]
In the present invention, there is a correspondence between the first game world and the second game world. This correspondence relationship is, for example, a spatial correspondence relationship. For example, the first game world is an upper game world, the second game world is a lower game world, and the first game world is below the first game world. There may be a case where the second game world exists and has a vertical correspondence. In addition, there may be a case where the first game world and the second game world have a left-right correspondence relationship.
[0010]
In the game world configured as described above, a part of each game world is displayed on the first display means and the second display means, and a part of the first game world displayed on the first display means. Display control is performed so that the area corresponds to a partial area of the second game world displayed on the second display means.
[0011]
According to the present invention, since the information of the corresponding area in the game world where no character exists is presented, the interest of the game can be increased. The player may advance the game while looking at both display means, but the player plays by looking only at the display means on which the character exists, and the person who is watching the game other than the player has the character Since the player can be informed of the information by looking at the display means that does not, the person other than the player is also interested in participating in the game.
[0012]
In addition, for example, information on both game worlds is presented in conjunction with the movement of the character, so that, for example, there is a correspondence relationship that there is a second game world below the first game world. If the character is present in the first game world, the second game world information displayed on the second display means is information below the current position of the character. Can be recognized. Thereby, for example, when the character exists in the first game world and the item is displayed on the second display means, the player can recognize that there is an item in the lower layer direction of the current position of the character, It can be a clue to get the item.

The floor will correspond spatially.
[0030]
The game world of the first floor portion output from the second game machine 30 is displayed on the television monitor 60, and the game world of the second floor portion is displayed on the LCD 25 by the first game machine 20. The game world of the first floor displayed on the TV monitor 60 corresponds to the game world of the second floor displayed on the LCD 25. That is, when the character 91 is present on the first floor portion, the peripheral area of the character 91 is displayed on the television monitor 60, and the second floor portion area corresponding to the area displayed on the television monitor 60 is displayed on the LCD 25. When the character 91 is present on the second floor portion, the LCD 25 displays the peripheral area of the character 91, and the first floor portion area corresponding to the area displayed on the LCD 25 is displayed on the television monitor 60. That is, the display control is performed so that the area of the first floor displayed on the television monitor 60 and the area of the second floor displayed on the LCD 25 are areas corresponding to the top and bottom in the game world.
[0031]
The character 91 is displayed on either the television monitor 60 or the LCD 25. That is, the character 91 is displayed on the television monitor 60 when the character 91 is present on the first floor portion, and is displayed on the LCD 25 when the character 91 is present on the second floor portion. In this embodiment, the character 91 is fixedly displayed, and the background (maze that is a game world) is relatively scroll-displayed in accordance with the movement operation of the character 91. Note that the character 91 may be moved and displayed, and the game world (maze) may be scrolled as necessary.
[0032]
In FIG. 3, the character 91 currently exists in the game world on the first floor. At this time, as shown in FIG. 4, the peripheral area (area 60 a) of the character 91 is displayed on the television monitor 60. In addition, the game world (region 25a) corresponding to the second floor is displayed on the LCD 25.
[0033]
When the player operates the operation switch 26a, the character 91 moves in the game world. In this embodiment, since the character 91 is fixedly displayed, the game world (maze) is scroll-displayed according to the movement operation of the character 91.
[0034]
When the character 91 exists in the game world of the first floor portion, the movement operation of the character 91 is performed by the operation switch 26a both when the character 91 exists in the game world of the second floor portion. That is, when the character 91 is present in the game world on the first floor, the character 91 displayed on the television monitor 60 is moved by the operation of the operation switch 26a. When the character 91 exists in the game world on the second floor, the character 91 displayed on the LCD 25 is moved by the operation of the operation switch 26a. This is convenient because the player can use the same operation switch regardless of which game world the character is in.
[0035]
From the state shown in FIG. 3, it is assumed that the player operates the operation switch 26a to move the character 91 in the lower right direction to enter the state shown in FIG. 5 (a state where the character 91 is in the vicinity of the stairs 92a). At this time, the screen shown in FIG. 6A is displayed on the television monitor 60, and the screen shown in FIG. 6B is displayed on the LCD 25.

In the state shown in FIG. 5, when the player operates the operation switch 26a and further moves closer to the stairs 92a, the character 91 moves up the stairs and moves to the game world on the second floor. The screen shown in FIG. 7A is displayed, and the screen shown in FIG.
[0037]
The screen (TV monitor or LCD) on which the character is displayed changes before and after the stairs are moved up and down (movement of the game world). That is, the display of the character 91 disappears from the television monitor 60, and the character 91 is displayed on the LCD 25 (the character 91 has not been displayed so far). By performing such display control, it is possible to give the player a visual effect as if the character 91 has moved from the world of the television monitor to the world of the LCD, and the player can feel the movement of the character 91 between the worlds. be able to.
[0038]
When the character 91 is positioned in the pit 93 on the second floor, the character 91 falls and moves to the game world on the first floor. At this time, the display of the character 91 displayed on the LCD 25 disappears, and the character monitor 91 is displayed on the television monitor 60.
[0039]
When the character has some item, game control may be performed such that the item is used to move the game world by operating the operation switch 21b or the like. For example, if a jump item is used on the first floor portion, the character 91 may move to the corresponding second floor portion. In this case, the display of the character 91 displayed on the television monitor 60 disappears, and a display in which the character 91 appears on the LCD 25 is displayed.
[0040]
Further, game control may be performed such that the game world moves when the ability value of the character reaches a predetermined value or when an event is cleared.
[0041]
Furthermore, from the state shown in FIG. 7, it is assumed that the player operates the operation switch 26a to move the character 91 upward, resulting in the state shown in FIG. At this time, the screen shown in FIG. Further, the screen shown in FIG. 9B is displayed on the LCD 25.
[0042]
Here, an item 94 is displayed on the television monitor 60. From the display on the television monitor 60, the player can recognize that an item exists on the first floor corresponding to the current position of the character 91. That is, the player can obtain position information of items existing in another game world (the first floor portion) and use it for future game progress.
[0043]
In addition, if the player only looks at the display on the LCD 25 and does not look at the display on the TV monitor 60, the player may not be aware of the presence of the item 94. If so, the player can notice the presence of the item 94 and teach it to the player. In this way, a person other than the player also enjoys participating in the game.

Specifically, referring to the character position data stored in the area 2231 of the RAM 22, it is determined whether the game world in which the character 91 exists is the first floor portion or the second floor portion (as described above, the character position data Contains the game world identification number). If it is determined that the character 91 is present on the second floor portion, in step S306, processing for updating the character position data is performed based on the operation data of the operation switch 26a. Specifically, the X and Y coordinates of the character position data are updated in response to pressing of the operation switch 26a (cross switch) up, down, left, and right (when there is an obstacle such as a maze wall and the character cannot be moved). Do not update). After step S306, in step S307, it is determined whether or not the updated character position is a specific location. Specifically, it is determined whether or not the position is the staircase 92b or the pit 93. If it is determined in step S307 that the updated character position is a specific location (step 92b or pit 93), the character 91 should be moved to the first floor game world in step S308. Is moved (specifically, the game world identification number of the character position data is updated), and the process of deleting the display of the character 91 from the LCD 25 is performed in step S309. After step S309, the process proceeds to step S310. If it is determined in step S307 that the updated character position is not a specific location (step 92b or pit 93), the process proceeds to step S310. After the process of transmitting the updated character position data to the second game machine 30 in step S310, the display of the game world (maze) is scrolled in accordance with the updated character position data in step S311. Processing is performed. After step S311, the process proceeds to step S313.
[0060]
If it is determined in step S305 that the character 91 is present on the first floor portion, processing for transmitting operation data of the operation switch 26a to the second game machine 30 is performed in step S312. The operation data transmitted to the second game machine 30 is stored in the operation data buffer 361. After step S312, the process proceeds to step S313.
[0061]
In step S313, it is determined whether or not the character exists on the first floor portion. If it is determined that the second floor portion exists, the process proceeds to step S319. When it is determined that the first floor portion exists, it is determined in step S314 whether or not character position data is transmitted from the second game machine 30 (step S408 in FIG. 16 described later). If it is determined that there is no transmission of character position data, the process proceeds to step S319. If it is determined that the character position data has been transmitted, an update process for writing the received character position data in the area 2231 of the RAM 22 is performed in step S315. By this processing, the character position data in the first game machine 20 and the character position data in the second game machine 30 are matched. Further, in step S316, the game world of the LCD 25 is based on the updated character position data. By performing the (maze) change process (scroll process), a display in conjunction with the television monitor 60 is displayed on the LCD 25. After step S316, in step S317, it is determined whether or not the position of the updated character is in the second floor part (that is, whether or not the character 91 has moved from the first floor part to the second floor part). If it is determined that the updated character position remains on the first floor, the process proceeds to step S319. If it is determined that the position of the updated character is in the second floor, a process for displaying the character on the LCD 25 is performed in step S318, and the process proceeds to step S319.
[0062]
In step S319, it is determined whether or not the game is cleared or the game is over. If the game is cleared or the game is over, the game process is terminated. If it is not game clear or game over, the process returns to step S303.
[0063]
As described above, when it is determined that the character 91 is present on the second floor when the operation switch 26a is operated, the first game machine 20 (CPU 21) determines that the character is based on the operation data in step S305. The process (S306 to S310) related to the movement of is performed. Further, when it is determined that the character 91 is present on the first floor portion, the operation data is transferred to the second game machine 30 and the second game machine 30 performs processing related to the movement of the character (described later). 16, steps S404 to S408) are performed.
[0064]
Furthermore, when it is determined that the character 91 is present on the first floor (S313), the image displayed on the LCD 25 is changed based on the processing result by the second game machine 30 through steps S314 to S318.

Steps S402 and S413 are processes based on the existence world determination program 3214. Steps S407 and S414 are processing based on the character display control program 3215. Steps S401, S409, and S412 are processes based on the game world display control program 3216. Step S411 is processing based on the interlock control program 3217. Steps S408 and S410 are processes based on the communication control program 3218. Step S415 is processing based on the other game processing program 3219.
[0066]
First, in step S401, a process of displaying the maze of the first floor portion corresponding to the initial value of the character position data stored in the area 3231 of the RAM 32 on the television monitor 60 is performed. (The character 91 is not displayed on the television monitor 60 because it exists in the game world of the first game machine 20 in the initial state (that is, the game world on the second floor).)
[0067]
Next, in step S402, it is determined whether or not the character 91 exists on the first floor. If it is determined that the data exists on the first floor, it is determined in step S403 whether data exists in the operation data buffer 361 or not. If it is determined that there is no operation data, the process proceeds to step S415. If it is determined that the operation data exists, the character position data is updated based on the operation data in step S404. Specifically, a process of changing the character position data according to the up / down / left / right direction of the operation data of the operation switch 26a stored in the operation data buffer is performed.
[0068]
After step S404, in step S405, it is determined whether or not the updated character position is a specific location (step 92a). If not, the process proceeds to step S408. If it is a specific place, in step S406, the character 91 is moved up to the staircase and moved to the second floor game world, and in step S407, the character 91 is deleted from the television monitor 60. It is. After step S407, the process proceeds to step S408.
[0069]
After the process of transmitting the updated character position data to the first game machine 20 is performed in step S408, the display of the game world (maze) is scrolled based on the updated character position data in step S409. Processing is performed.
[0070]
If it is determined in step S402 that the character 91 is on the second floor, it is determined in step S410 whether or not character position data has been transmitted from the first game machine 20 (step S310 in FIG. 14). . If it is determined that there is no transmission, the process proceeds to step S415. If it is determined that transmission has been performed, a process of writing the received character position data in the area 3231 of the RAM 32 is performed in step S411. By this processing, the character position data in the first game machine 20 and the character position data in the second game machine 30 are matched. Furthermore, in step S412, a game world (maze) change process (scroll process) of the TV monitor 60 is performed based on the updated character position data, so that the display in conjunction with the LCD 25 is displayed on the TV monitor 60. become.
[0071]
After step S412, in step S413, it is determined whether or not the updated character position is the first floor portion. That is, in step S308 of FIG. 14, it is determined whether or not the process of moving the character 91 from the second floor portion to the first floor portion is performed. Specifically, the character position stored in the area 3231 of the RAM 32 is determined. Judgment based on data. If it is determined that the updated character position is the second floor portion, the process proceeds to step S415. If it is determined that the updated character position is the first floor portion, a process of displaying the character 91 on the LCD 25 is performed in step S414.
[0072]
In step S415, it is determined whether or not the game is cleared or the game is over. If the game is cleared or the game is over, the game process is terminated. If it is not game clear or game over, the process returns to step S402.
