Description

  The present invention relates to a game apparatus suitable for causing a player to play a game with a sense of tension even when the score difference is wide, a method for controlling the game apparatus, and a program for realizing these on a computer About.

  Conventionally, various game devices have been proposed for realizing a battle game in which players battle each other. For example, Patent Document 1 listed below discloses a technique for appropriately classifying players into classes in order of ability. By using this technology, players with the same class can play against each other and play with a sense of tension.

Japanese Patent No. 3653088

  However, if the players of the same class do not play against each other, such as when there is a large difference in the ability of the players, the score of both will spread too much in the middle of the game, the advantageous side will win and escape, The tension of the game may be lost and the tension of the game may be lost. Therefore, there is a strong demand for a technique for maintaining a sense of tension in a game by giving a possibility of reversal even when the score difference is wide.

  The present invention solves the above-described problems, and a game device suitable for causing a player to play a game with a sense of tension even when the score difference is greatly widened, and a method for controlling the game device An object of the present invention is to provide a program that realizes these on a computer.

  In order to achieve the above object, the following invention is disclosed in accordance with the principle of the present invention.

  The game device according to the first aspect of the present invention has an input reception unit, an evaluation value acquisition unit, a score setting unit, and a winner determination unit, in which a first player and a second player are played against each other. Configure.

  That is, the input receiving unit receives operation inputs from the first player and the second player.

  When the game realized by the game device is a shooting game, the operation input is an instruction input in which each player operates the controller to aim at the target and then presses the button corresponding to the trigger. It corresponds to.

  In the case of a fighting fighting game, this corresponds to a command input for selecting an action that each player takes on his / her character. However, the present invention can be applied to a game where two players are fighting. Is possible.

  In a rhythm game in which keys, buttons, musical instruments, and the like are operated in accordance with the musical score displayed on the screen and the accompaniment output by sound, the operation corresponds to an operation input.

  The battle between the first player and the second player may be a situation where two players use the same game machine, or a situation where a battle is made by communicating over a network, Even in a situation where adjacent game machines perform communication by performing ad hoc communication, the present invention can be applied to any case.

  Further, one of the players may be applied to a so-called CPU (Central Processing Unit) battle as a computer generating operation input based on an algorithm prepared in advance.

  On the other hand, when the received operation input matches a predetermined achievement condition, the evaluation value acquisition unit acquires a value associated with the matching achievement condition (hereinafter referred to as “basic value”) as an evaluation value.

  In the above shooting game example, if the center of the target corresponds to the predetermined achievement condition and the distance between the aim and the center of the target is within a certain range, the two match. The score obtained when shooting is successful corresponds to the basic value.

  In the example of the fighting game described above, when the present invention is applied to a command input made by operating buttons or the like in a predetermined order, the time required for button operation is within a predetermined time, and / or Alternatively, when the error in button operation timing is within a predetermined error range, the achievement condition is typically met. In this case, the parameter of the attack power and defense power of the technique given by the command input corresponds to the basic value.

  In the case of a rhythm game, when the operation is performed at the timing to be operated, that is, when the time error of the operation input is within the predetermined error range, the predetermined achievement condition is satisfied. become. In general, a parameter is assigned to each timing to be operated, and this parameter corresponds to a basic value.

  Further, the score setting unit calculates a point that is linked to the acquired evaluation value, and a player who gives an operation input that matches the achievement condition associated with the evaluation value is more advantageous than before only for the calculated point. Thus, the score of a 1st player and a 2nd player is set.

  In the case of the above shooting game or rhythm game, the obtained evaluation value is typically used as a point as it is.

  On the other hand, when one player attacks the other player in the fighting fighting game, it is typical to think as follows. That is, after determining the success or failure of the attack / defense based on the combination of accepted operation inputs, the attack skill evaluation value acquired for the attacking player and the defense set for the defending player prior to the attack. If the difference between the technique and the evaluation value is positive, the value is set as a point. In other cases, 0 is set as a point.

  In the case of a shooting game, the calculated points are typically added to the score of the player who made the operation, but in the case of a battle game, the operation input is performed. Typically, it is subtracted from the score of the missing player.

  Then, when the predetermined end condition is satisfied, the winner determination unit determines any advantageous player as a winner based on the difference in scores between the first player and the second player.

  The predetermined ending condition is a condition for ending the battle. In the case of a shooting game, when both players repeatedly shoot a predetermined number of times, in the case of a battle fighting game, the score of one player is 0. It is typical to provide a time limit in addition to these conditions.

  In the case of a rhythm game, there is a time limit during which the game is played from the start to the end of the performance of the music corresponding to the musical score, and the end condition is determined accordingly.

  On the other hand, the evaluation value acquisition unit replaces the basic value associated with the predetermined achievement condition based on the score difference between the first player and the second player (hereinafter referred to as “bonus value”). Is obtained as an evaluation value.

A typical situation in which a bonus value is acquired as an evaluation value is the following situation.
(1) When the score difference between the first player and the second player is equal to or greater than a predetermined threshold.
(2) The score difference between the first player and the second player is equal to or greater than a predetermined threshold value, and the change in the score difference in the most recent predetermined period is not a decreasing trend.

  If the score difference between the two players is large to a certain extent, especially if the score difference does not tend to shrink, that is, if the score difference tends to be maintained or widened, the advantageous player will be out of hand and the disadvantaged side May lose their motivation and undermine the tension of the game.

  Therefore, in the present invention, in such a situation, the player on the disadvantaged side can make a one-time reversal so that the tension of the game is maintained.

  For example, in the case of a shooting game or rhythm game, the evaluation value when the operation is successful is increased from the basic value to a bonus value that can be reversed once, and in the case of a fighting fighting game, the strength of the attack technique is evaluated. The value is increased from the basic value to a bonus value that can be reversed once.

  However, the evaluation value acquisition unit tightens the criterion for determining whether or not the received operation input matches the predetermined achievement condition as the ratio of the bonus value to the basic value increases.

  This is to ensure the fairness of the game. When the evaluation value is increased from the basic value to the bonus value, the possibility of successful operation input is reduced according to the degree of the increase.

  As described above, it is determined whether or not the achievement condition is satisfied when the operation input is within a certain error range. By adjusting the size of the error range, the operation input succeeds. It is possible to reduce the possibility.

  As described above, the present invention provides a game having a rule that does not make the player feel unnatural even if the score obtained for a certain operation input varies greatly depending on the situation, for example, a shooting game or a fighting game. In addition to the above, it is particularly suitable for RPG (Roll Playing Game) or the like in which a deadly command that can be defeated even if it is activated is prepared from the beginning.

  According to the present invention, even when the game score difference is greatly widened, the player can play a game with a sense of tension.

  Further, in the game device of the present invention, the evaluation value acquisition unit receives the received operation input and the predetermined value when the error between the received operation input and the target associated with the predetermined achievement condition is within a predetermined error range. The score difference between the first player and the second player, or a value obtained by adding a predetermined positive number to the score difference, is the bonus value, and is inversely proportional to the ratio of the bonus value to the basic value As described above, the criterion can be made stricter by reducing the predetermined error range.

  Here, in the case of a shooting game, the error between the operation input and the target associated with the achievement condition corresponds to the distance between the center of the target (target associated with the achievement condition) and the aim (operation input). In the case of a competitive fighting game, this corresponds to a difference between the timing of input assigned to the command and the timing of actual operation input. If these distances and deviations are within a predetermined error range, shooting and command input are successful.

  In addition, by setting the bonus value to be equal to or greater than the score difference between the two, it is set so that the disadvantaged player can catch up with the advantageous player in one shot or reverse.

  Furthermore, an error range that determines the success or failure of the operation input is set to be inversely proportional to the ratio of the bonus value to the basic value. For example, if the bonus value is 10 times the basic value, the error range is set to 1/10.

  According to the present invention, even when the game can be reversed once, when the point obtained by one shot becomes large, by appropriately reducing the probability of successful operation input according to this, The fairness of the game can be secured.

  In the game device of the present invention, the score setting unit obtains a non-negative adjustment value associated with the current game situation, and subtracts the obtained adjustment value from the obtained evaluation value to obtain a point. Can be configured.

  For example, as in a fighting fighting game, two of “attack” and “defense” are often considered in the game battle. Considering the operation input of one player as “attack” and the operation input of the other player as “defense”, the basic value and evaluation value are “attack” strength, and the adjustment value is “defense” strength. It corresponds to. These values are generally non-negative (0 or more). By subtracting the adjustment value from the evaluation value, it is possible to correct the evaluation value, thereby further complicating the game.

  For example, in the case of a fighting fighting game, the defense posture and strength of the defense taken by the defending player by the previous operation input, and the attack taken by the attacking player by the attacking player by this operation input Depending on the type of combination, the evaluation value will be corrected, and the damage received by the defending character will not be the evaluation value itself, but will be a value that is reduced according to the strength of the defense. is there.

  In the above shooting game and rhythm game, the obtained evaluation value is generally used as a point as it is, but by setting an adjustment value according to the rule setting, `` the opponent is successful But if you succeed, you won't get any damage "," If you succeed, you can do more damage if you succeed "," If you fail, if you succeed, you will get more damage " It is also possible to adopt this aspect.

  According to the present invention, instead of using the basic value as a point or the bonus value as a point, the basic value and the evaluation value which is a bonus value are adjusted to be small according to the game situation, By using the adjustment result as a point, the content of the game can be made more complicated.

  In the game device of the present invention, the predetermined threshold can be configured to be a constant having a magnitude exceeding a basic value associated with a predetermined achievement condition.

  As described above, the basic value is a value corresponding to a point that can be obtained by one operation input. Accordingly, the fact that the predetermined threshold value is larger than any of the basic values corresponds to a situation where there is no one-time reversal (unless a bonus value is adopted).

  The present invention corresponds to a preferred embodiment for setting a score difference that will not maintain the tension of the game.

  In the game device of the present invention, when a bonus value is acquired as an evaluation value, an image and sound associated with the ratio of the bonus value to the basic value are presented to the first player and the second player. Can be configured.

  The present invention relates to a preferred embodiment of the above invention, and when a bonus value is acquired, presents to the player that the situation is that a special-kill one-shot reverse command is activated. is there.

  According to the present invention, when a player who has been advantageous until then is suddenly reversed by an operation input of a player who has been disadvantaged until then, the player has been reversed based on the rules of the game, and Details can be learned from video and audio.

  A control method according to another aspect of the present invention controls a game device that causes a first player and a second player to play against each other, and the game device includes an input reception unit, an evaluation value acquisition unit, a score setting unit, and a winner determination. The control method includes an input reception process, an evaluation value acquisition process, a score setting process, and a winner determination process, and can be configured as follows.

  That is, in the input reception process, the input reception unit receives operation inputs from the first player and the second player.

  On the other hand, in the evaluation value acquisition step, when the received operation input matches a predetermined achievement condition, the evaluation value acquisition unit sets a value (hereinafter referred to as “basic value”) associated with the matching achievement condition. Obtained as an evaluation value.

  Furthermore, in the score setting step, the score setting unit calculates points that are linked to the acquired evaluation value, and the player who gave the operation input that matches the achievement condition associated with the evaluation value is only the calculated point The score of the first player and the second player is set so as to be more advantageous than before.

  In the winner determination step, when a predetermined end condition is satisfied, the winner determination unit determines any advantageous player as a winner based on the score difference between the first player and the second player.

  On the other hand, if the score difference between the first player and the second player is greater than or equal to a predetermined threshold and the change in the score difference in the most recent predetermined period is not a decreasing trend, the evaluation value acquisition step satisfies the predetermined achievement condition. In place of the associated basic value, a value greater than the score difference (hereinafter referred to as “bonus value”) shall be acquired as an evaluation value, and whether or not the accepted operation input matches the predetermined achievement condition. The criterion is made stricter as the ratio of the bonus value to the basic value is larger.

  A program according to another aspect of the present invention is configured to cause a computer to function as each unit of the game device.

  The program of the present invention can be recorded on a computer-readable information storage medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory.

  The above program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information storage medium can be distributed and sold independently from the computer.

  Advantageous Effects of Invention According to the present invention, a game device suitable for causing a player to play a game with tension even when the score difference is greatly widened, a method for controlling the game device, and these are realized by a computer A program can be provided.

Chat communication log (record) data and the like are stored in a rewritable manner. The user can record these data in the external memory 106 as appropriate by inputting an instruction via the controller 105.

  A DVD-ROM mounted on the DVD-ROM drive 108 stores a program for realizing the game and image data and audio data associated with the game. Under the control of the CPU 101, the DVD-ROM drive 108 performs a reading process on the DVD-ROM loaded therein, reads out necessary programs and data, and these are temporarily stored in the RAM 103 or the like.

  The image processing unit 107 processes the data read from the DVD-ROM by an image arithmetic processor (not shown) included in the CPU 101 or the image processing unit 107, and then processes the processed data on a frame memory ( (Not shown). The image information recorded in the frame memory is converted into a video signal at a predetermined synchronization timing and output to a monitor (not shown) connected to the image processing unit 107. Thereby, various image displays are possible.

  Various types of monitors that can display images can be used depending on the mode of the information processing apparatus 100. For example, a small liquid crystal display is typically used as a monitor for a portable terminal device. In particular, when a touch screen is used as the controller 105, the display panel of the touch screen functions as a monitor. In a game machine connected to the television device, the television device is used as a monitor, and a display device such as a CRT (Cathode Ray Tube) or a plasma display can be used as the monitor of the server device.

Further, not the controller 105 but a keyboard or a mouse is used as an input device.

  FIG. 3 is an explanatory diagram showing a schematic configuration of the game device according to the present embodiment. Hereinafter, a description will be given with reference to FIG.

  Using the game device 301 according to the present embodiment, the first player and the second player play a game against each other. Here, the game apparatus 301 includes an input receiving unit 302, an evaluation value acquiring unit 303, a score setting unit 304, a winner determining unit 305, and a score storage unit 306.

  Hereinafter, a shooting game will be mainly described as an example of the game performed here, and a case where the game is applied to a battle fighting game, a rhythm game, a dance game, or the like will be described as appropriate.

  First, the input receiving unit 302 receives operation inputs from the first player and the second player. Under the control of the CPU 101, the controller 105 functions as the input receiving unit 302.

  In the case of a shooting game, a pressing operation of the arrow keys (↑ button 201, ↓ button 202, ← button 203, and → button 204) of the controller 105 for moving the aim, and a determination key of the controller 105 for pulling the trigger The pressing operation of the (◯ button 205) corresponds to an operation input.

  On the other hand, the evaluation value acquisition unit 303 determines whether or not the received operation input matches a predetermined achievement condition, and if it matches, treats the operation input in the game as successful and handles the success. In order to calculate a reward, a basic value associated with the achievement condition is acquired as an evaluation value. The CPU 101 functions as the evaluation value acquisition unit 303.

  In the case of a shooting game, no achievement condition is set for the pressing operation of the arrow keys (↑ button 201, ↓ button 202, ← button 203, and → button 204) of the controller 105. That is, only the aiming position is updated.

  On the other hand, for the pressing operation of the determination key (○ button 205) of the controller 105, it is determined that the operation input matches the achievement condition when the distance between the target position and the aiming position is within a predetermined distance. To do. The basic value corresponds to the number of points assigned in advance to the target.

  Further, the score setting unit 304 calculates a point that is linked to the acquired evaluation value, and the player who has given the operation input that matches the achievement condition associated with the evaluation value is more advantageous than before only the calculated point. The score of a 1st player and a 2nd player is set so that it may become. The CPU 101 functions as the score setting unit 304.

  The function of the score setting unit 304 is widely used in a game in which a player battles, and in the case of a shooting game, the acquired evaluation value becomes a point as it is, and the point is added to the score of the player. . In the case of a battle game, physical strength parameters are prepared for the characters operated by each player. When the operation input is successful, the physical strength parameters of the opponent character are subtracted by the calculated points.

  In this way, the score difference between the first player and the second player varies by the calculated point.

  Note that the score of each player and the history of changes in the score for the most recent fixed period are stored in the score storage unit 306. Typically, the RAM 103 functions as the score storage unit 306.

  Then, when a predetermined end condition is satisfied, the winner determination unit 305 determines any advantageous player as a winner based on the difference in scores between the first player and the second player. The CPU 101 functions as the winner determination unit 305.

  The predetermined ending condition is a condition for ending the battle. In the case of a shooting game, when both players repeatedly shoot a predetermined number of times, in the case of a battle fighting game, the score of one player is 0. It is typical to set a time limit in the case of becoming.

  Such a configuration is typical for a fighting game, but in the present invention, it is automatically determined that the situation has been such that the sense of tension of the game has been lost. As an evaluation value acquired when the input is successful, a bonus value described later is adopted instead of the basic value.

  As described above, the score setting unit 304 calculates points based on the evaluation value. The evaluation value and the point are linked, and the larger the evaluation value, the larger the point, and the evaluation value and the point match. Alternatively, a value obtained by subtracting a parameter corresponding to the game situation from the evaluation value is a point.

  The conditions for the bonus value to become the evaluation value, the bonus value calculation method, and the method for ensuring the fairness of the game when the bonus value is adopted will be described in detail below.

  FIG. 4 is a flowchart showing a flow of control of game processing executed by the game device according to the present embodiment. Hereinafter, a description will be given with reference to FIG.

  When the information processing apparatus 100 loads a program from a DVD-ROM attached to the DVD-ROM drive 108, the CPU 101 first performs various initializations for causing the information processing apparatus 100 to function as the game apparatus 301. (Step S401). In this embodiment, at this time, the area for storing the score s [1] of the first player and the score s [2] of the second player in the RAM 103 is cleared to 0 (s [1] ← 0, s [ 2] ← 0), the error range d [1] of the hit determination of the first player and the error range d [2] of the hit determination of the second player are set to a positive constant value r (d [1] ← r, d [2] ← r).

  Then, the CPU 101 controls the image processing unit 107 to display a game screen on the monitor (step S402), acquires the pressing state of the controller 105, and accepts operation inputs from the first player and the second player ( Step S403). Then, the game state is updated according to the received operation input (step S404).

  FIG. 5 is an explanatory diagram showing an example of a screen display when the present embodiment is applied to a shooting game. Hereinafter, a description will be given with reference to FIG.

  On the screen 401, a circular target 411 for the first player (position a [1]) and a target 451 for the second player (position a [2]) are displayed. The targets 411 and 451 are displayed with sizes d [1] and d [2], respectively, and randomly walk in the screen at a constant speed. For the targets 411 and 451, the point “100” obtained when the shooting is successful is illustrated.

  The cross-shaped aim 412 for the first player (position p [1]) and the aim 452 for the second player (position p [2]) are the arrow keys (↑ button 201) of the controller 105 that the player uses. , ↓ button 202, ← button 203, and → button 204) move in that direction.

  That is, the game state in this embodiment corresponds to the positions of the aim 412 for the first player and the aim 452 for the second player.

  The screen 401 displays “3400 points” in the score area 413 of the first player, and “3300 points” in the score area 453 of the second player. The score difference between the two is 100 points, which is not so large.

  Next, whether or not the operation input received from one of the players (hereinafter, the first player and the second player who gave the operation input is the i-th player) matches the achievement condition. It is determined whether or not the operation input is a determination target (step S405). In the present embodiment, the pressing operation of the determination key (◯ button 205) of the controller 105 corresponds to the operation input to be determined. When it is not a determination target (step S405; No), the process proceeds to step S421.

  On the other hand, when it is a determination target (step S405; Yes), it is determined whether or not the operation input matches the achievement condition, that is, in this embodiment, whether or not the shooting is successful (step S406).

  Here, the distance between the aim of the i-th player and the target corresponds to the distance | a [i] -p [i] | between the position a [i] and the position p [i]. If this is considered as an error, whether the shooting was successful or not is determined if the error is within the error range d [i], that is, | a [i]-p [i] | ≦ d [i] It can be determined by whether or not it has been done. When the shooting has failed (step S406; No), the process proceeds to step S421.

  On the other hand, when the shooting is successful (step S406; Yes), the basic value K assigned to the target is acquired (step S407). In the present embodiment, the basic value K assigned to the target is a constant, but the basic point may be changed when the shape or size differs for each target.

Points X to be added to the score s [i] of the i-th player
X = K / d [i]
(Step S408). Since d [1] = d [2] = r at the stage just starting the game, the point X calculated here is equal to the constant K / r.

  Next, the point X is added to the score s [i] of the i-th player stored in the RAM 103 (step S409), and the process proceeds to step S421.

  The processing performed in steps S401 to S409 described above is not essentially different from the processing performed in the conventionally proposed shooting games. As will be described later, the feature of this embodiment is that the tension of the game is maintained by appropriately changing d [1] and d [2].

  Now, after the determination of the operation input of a general competitive game is over, the CPU 101 determines whether or not the game is in a so-called “winning escape state” (step S421).

It is judged that it is a winning and escaping state.
(A) In the most recent judgment period, a state where the difference of the player scores | s [1] -s [2] | is larger than a predetermined threshold value M, and
(B) This is a case where the condition that the player's score difference | s [1] -s [2] |

  In order to make such a determination, it is easiest to store the history of the player's scores s [1] and s [2] in the RAM 103 in the most recent determination period.

  Here, in order to determine that “a certain value is not in a decreasing trend in the most recent judgment period (that is, in a maintenance tendency or an increase tendency)”, the judgment period is divided into the first half and the second half, The average value may be compared with the average value in the latter half.

  If the former is larger than the latter, the value tends to decrease. If the former is smaller than the latter, the value tends to increase. If the former is equal to the latter, the value tends to be maintained.

  In addition, the predetermined threshold M is generally set to a value that is somewhat larger than a predetermined value K / r of points that can be added in one shooting, and most simply, the predetermined value K / r is 5 It is determined as a constant as appropriate according to the content of the game, such as double, 10 times, and 20 times.

  It should be noted that the “last judgment period” may be determined by a constant in seconds or minutes. In addition, in the case of a shooting game in which the game is played according to the number of times of shooting, the overall number of times of shooting is determined by multiplying an appropriate constant between 0 and 1, or the remaining number of shooting is set as an appropriate constant between 0 and 1. There can also be a method of determining by multiplication.

For example, if the remaining number of shots is y, if one player misses all shots and the other player succeeds in shooting, the score difference between them will be K / r × y. Therefore, the predetermined threshold M is a constant α satisfying 0 <α <1,
M = α × K / r × y
And In this case, the threshold value M changes as the play progresses. As α, an appropriate constant such as 1/2 or 1/3 is typically selected.

In this way, if the battle becomes a unilateral development, or if the difference is wide open and the change is lost, the advantageous player will be alert, the disadvantaged player will lose motivation, and the game tension will be lost. It will be broken. Therefore, when the player is in the “winning and escaping state” (step S421; Yes), out of the score s [1] of the player who is currently disadvantaged, that is, the score s [1] of the first player and the score s [2] of the second player The error range d [j] of the j-th player having the smaller score s [j] is calculated using the function f (·, ·)
d [j] ← f (| s [1] -s [2] |, K / r)
(Step S422), the process proceeds to step S431.

Here, the most typical function f (a, b) is
f (a, b) = r × (b / a)
It is. This defines an error range so as to be inversely proportional to the current score difference a.

  In the present embodiment, the sizes of the targets 411 and 451 displayed on the screen 401 are determined by values d [1] and d [2]. Therefore, the current disadvantageous j-th player's target is that if the score difference | s [1] -s [2] | The criteria for this will become stricter.

Here, when a specific calculation is performed using the above function,
d [j] ← K / (| s [1] -s [2] |)
It becomes. At this time, if the jth player succeeds in shooting with the next operation input, the point X obtained at that time will be
X = K / d [j] = K / [K / (| s [1] -s [2] |)] = | s [1] -s [2] |
It is.

  Therefore, it is difficult for the j-th player to make the shooting successful, but if it succeeds, the player can catch up with the opponent player's score in one shot.

In addition, using an appropriate positive constant W as the function f (a, b)
f (a, b) = r × b / (a + W)
If so, the point obtained under these conditions is | s [1] -s [2] | + W. In this case, if the shooting is successful, the j-th player can exceed the opponent's score by W, and it is possible to reverse one shot. Especially in this case, if the value is set in a range such as 0 <W ≦ K / r, the score is very close and re-reversal is possible immediately. A feeling can be given to a player.

  FIG. 6 is an explanatory diagram illustrating an example of a screen display of a shooting game in a state where the reversal is possible. Hereinafter, a description will be given with reference to FIG.

  In this figure, the screen 401 displays “4300 points” in the scoring area 413 of the first player, and “3450 points” in the scoring area 453 of the second player. It ’s pretty big in terms. The target 411 of the first player is displayed in the same size as FIG. 5 with the point display of “100”, but the target 451 of the second player is displayed in the size of 1/10 of FIG. The point “1000” is displayed in a balloon 455 in the vicinity thereof.

  Although the error range of successful shooting is one-tenth, the points for success are 10 times, ensuring the fairness of the game and enabling one-shot reversal.

  Note that, instead of one-time reversal, two-way reversal or n-th reversal may be employed. In this case, the width of d [j] is twice or n times the above calculation result. Then, the points obtained when the operation input is successful will be half the above calculation result or 1/2 times the above calculation result. Therefore, according to the bonus value in this case, two successful shots or n Reversal is possible with successful launch.

  In the present embodiment, the fact that one-time reversal is possible is presented to the player according to the size of the target 451. In conjunction with this, if the shooting of the disadvantaged second player is successful, a screen display and audio output reporting that will cause both players to know why the reversal was possible. it can.

  On the other hand, when it is not in the “winning escape state” (step S421; No), the error range is returned to the default value as d [1] ← r, d [2] ← r (step S423), and step S431. Proceed to

  Then, it is determined whether or not the battle game should be ended based on whether or not a predetermined end condition is satisfied (step S431). If it should not be ended (step S431; No), the process returns to step S402. On the other hand, if it should be ended (step S431; Yes), one of the players is determined to be a winner and the other is determined to be a loser based on the current score difference, and this is indicated (step S432), and this process is terminated. For the determination of the ending condition and winning / losing, the same processing as that of a general game may be adopted.

  The embodiment in which the principle of the present invention is applied to the shooting game has been described above. Below, the difference with the said embodiment in the case of a battle fighting game and the case of a rhythm game and a dance game is demonstrated.

In the fighting fighting game, the following are employed as operation inputs.
(1) Instruction of movement to the character operated by the player. For example, it is performed by pressing an arrow key (↑ button 201, ↓ button 202, ← button 203, → button 204).
(2) Instructions to attack and defend the character operated by the player. For example, it is performed by pressing the circle button 205 or the x button 206.
(3) Instructions for special commands to generate special moves. A command is input by pressing the button 205, the x button 206, the △ button 207, the □ button 208, the ↑ button 201, the ↓ button 202, the ← button 203, the → button 204, etc. in the order assigned to the command. Is done.

In the fighting game,
(1) Accumulate the history of buttons and keys pressed within a certain time,
(2) If the pressing operation can be interpreted as a special command, a special technique associated with the special command is generated,
(3) If it can be interpreted that a special command is being input, it waits for the next pressing operation for a short time,
(4) When none of the above (2) and (3), it is general that the basic operation assigned to the key is performed. The state of the pressing operation that can be interpreted as a special command is typically set so as to satisfy the following conditions.
(A) The pressing operation is input within the time limit assigned to the command. For example, it is necessary to input within one second (within one frame of vertical synchronization interrupt as one frame, within 60 frames).
(B) The timing of the pressing operation is performed at a predetermined timing within a certain error range. For example, the timing of each input is periodically performed at intervals of 5 frames, and the error is within 3 frames.

  When the present invention is applied to such a fighting fighting game, the following method may be used.

  That is, a parameter constant indicating the strength of the special technique is assigned to the special command associated with the special technique. This parameter constant is used as a basic value, and this basic value is usually an evaluation value for a special move.

  Further, when a special technique occurs, the evaluation value is corrected by taking into consideration the posture and physical strength of the defense side, the presence / absence of a defense posture, and the like. This correction amount is an adjustment value.

  In general, when the defense side is sufficiently prepared for an attack, the adjustment value is subtracted from the evaluation value, and when the defense is unprotected, the adjustment value is set to 0 and the evaluation value is used as it is. The result of this correction is the point.

  Then, this point is subtracted from the physical strength parameter of the defending character. By this subtraction, the difference in the physical strength parameter between characters changes.

  When the difference in physical fitness parameters tends to expand or maintain, and the difference cannot be overturned even if one of the special moves is repeated several times (that is, a value obtained by multiplying the basic value assigned to the special move by a predetermined constant) If the difference in the physical strength parameter is larger than that), the battle game is shifted to the reverse challenge mode.

  In the reverse challenge mode, the evaluation value for a specific special move command is changed to a value that can be reversed once. Specifically, the basic value is multiplied by Y so that the difference is equal to or greater than the current physical fitness parameter difference. This method of obtaining Y corresponds to the method of obtaining 1 / d [j] in the above embodiment, and Y is greater than 1.

  On the other hand, the criteria for determining whether or not a special technique command has been input is tightened. For example, as shown in (a) above, when a time limit is assigned to command input, the time limit is shortened by a factor of Y. That is, reverse rotation is possible only when a command can be input at high speed in a short time.

  Further, as shown in (b) above, when a certain error range is provided at the command input timing, the error range is shortened by Y times. That is, reverse rotation is possible only when a command is input with an accurate rhythm.

  The latter method can be applied as it is to a game in which a key or button is pressed in accordance with BGM (Back Ground Music) or a foot switch is pressed to play a rhythm, play a musical instrument or dance. .

  In rhythm games and dance games, points are added by performing operation input at the correct timing according to the score displayed on the screen, but a certain error range is accepted as the criterion for "correct timing". ing. Therefore, if this error range is set to 1 / Y, it is required to input the operation accurately.

In general, in these games,
(A) The magnitude of the difference between the operation input and the achievement condition, that is, the error,
(B) a basic value assigned to the error;
Can be considered to be associated with each other.

  In addition, when the adjustment value in a game such as competitive fighting is considered in a more generalized manner, it can be considered as “a magnitude that can alleviate the damage of an attack from an enemy”.

  Therefore, an adjustment value can be considered even in a game such as a rhythm game or a shooting game in which two players face the same problem and the result is determined by whether or not the same achievement condition is satisfied.

  In this case, as the adjustment value, a parameter representing “accuracy of the operation input of the opponent player” is adopted, and most simply, the “basic value before correction” of the opponent player is used as it is, It is possible to adopt a value obtained by multiplying the “previous basic value” by a constant of 0 or more and less than 1.

  FIG. 7A is a graph showing a relationship between an evaluation value and an error when a basic value is adopted as an evaluation value in the above-described shooting game embodiment. FIG. 7B is a graph showing a relationship between an evaluation value and an error when a bonus value is adopted as the evaluation value. Hereinafter, a description will be given with reference to FIG.

  As shown in FIG. 7A, in the above shooting game, only two ways of shooting success or failure are considered. Therefore, the evaluation value becomes the basic value P when the error is 0 to D, but the error is D. If it exceeds, the evaluation value becomes 0.

  As can be seen by comparing these figures, the graph shown in FIG. 7B reduces the graph shown in FIG. 7A to Y times in the error direction, while expanding the scoring direction to Y times (in this figure, For ease of understanding, it is shown as Y = 2.) That is, in FIG. 7B, the evaluation value is the basic value Y × P when the error is 0 to D / Y, but the evaluation value is 0 when the error exceeds D / Y.

  In addition, in rhythm games and dance games, an evaluation value distribution may be adopted in which the smaller the error is, the higher the basic value that is assigned, that is, the basic value monotonously decreases with respect to the error. . FIG. 8A is a graph showing a relationship between an evaluation value and an error when a basic value is adopted as an evaluation value in such an embodiment, and FIG. 8B adopts a bonus value as the evaluation value in this embodiment. It is a graph which shows the relationship between the evaluation value in a case, and an error. Hereinafter, a description will be given with reference to FIG.

  In these figures, in order to enable the one-time reversal, it is only necessary to reduce the score direction by Y times while expanding the score direction by Y times.

  In the above description, a typical example is described in which two controllers are connected to one game device to perform a battle, but as described above, each player of the two game devices introduced via the server device. The same technology can be applied even when two players compete or when two game devices perform wireless communication ad hoc or peer-to-peer communication.

  Also, the present invention can be applied to so-called CPU battles. In this method, a program in which operation inputs are sequentially generated by a predetermined algorithm is operated, and the generated operation input is processed as being from one of the players.

  In addition, two types of achievement conditions for obtaining points are available: bonus points can be obtained and bonus points cannot be obtained. Then, there may be a mode in which a bonus point is awarded when the other player makes an operation mistake.

  That is, when the operation input of one player satisfies a predetermined operation input success condition (success) and the other player's operation input does not satisfy the predetermined operation input success condition (a mistake), the achievement condition Is to be satisfied.

  In such an embodiment, if the advantageous player makes a mistake, the disadvantaged player can reverse. Therefore, if the player on the advantageous side does not play seriously, the player will be allowed to reverse. That is, in order to prevent reverse rotation, it is necessary to play without paying attention to the end.

  Thus, according to the present embodiment, even when the score difference is greatly widened, it is possible to let the player play the game with a sense of tension until the end of the game.

  As described above, according to the present invention, a game device suitable for causing a player to play a game with a sense of tension even when the score difference is greatly opened, a method for controlling the game device, and A program for realizing these by a computer can be provided.
