Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a game apparatus and a game program in which a player object expressed on a game image attacks an enemy object by a player operating a controller.
[0002]
[Prior art]
In recent years, with the improvement in performance of computers included in game systems, three-dimensional games using three-dimensional computer graphics technology are increasing. In a three-dimensional game, objects composed of polygons such as player objects and terrain objects are arranged in a three-dimensional game space, and the state in the game space is displayed as a three-dimensional game screen from a predetermined viewpoint.
[0003]
On the other hand, in a so-called role-playing game in which a hero operated by a game player progresses based on a set story, there is a battle game in which the hero and enemy characters attack / defend each other during the progress of the game. May be inserted. When such a battle game is displayed in the above three-dimensional game, on the game screen, an object composed of polygons such as a player object (hero) and an enemy object (enemy character) operated by the player is arranged in the three-dimensional game space. Then, the battle scene is expressed according to the operation of the player.
[0004]
In such a battle game, it is necessary for the player to give an instruction such as attack / defense to the player object, and such an instruction is performed using a controller provided in the game device. The controller has a plurality of operation buttons, direction keys, sticks, and the like (hereinafter collectively referred to as an input unit), and when the player gives an attack / defense instruction, an operation corresponding to the instruction content Are performed using the input unit. Such instructions for attack / defense have different procedures for operating the input unit depending on the type of attack / defense, and if there are many types of attack / defense, the operation procedure corresponding to them becomes complicated. In order to facilitate such various attack / defense instructions, a game apparatus is disclosed in which n types of instructions are assigned to n input units, respectively (see, for example, Patent Document 1).
[0005]
In the game device disclosed in Patent Document 1, there are n types of attacks / defenses, and these are assigned to n buttons of the controller, respectively. Both the attack and defense can be instructed with one button, and whether it is an attack or defense is determined by whether or not the user has instructed the button first. Various movements of the player object can be expressed by changing the damage received by the defender by a combination of attack and defense. Further, when the attack and defense are two types of “front attack” and “back attack”, if the attack and defense match, it becomes disadvantageous defense, and if they are different, it becomes advantageous defense. This advantageous defense is earlier than the disadvantaged defense when the defender can give a return trick.
[0006]

[0007]
[Problems to be solved by the invention]
However, although the game device disclosed in Patent Document 1 can attack and defend with a single button, the defense is the same action as the attack on the game screen (as described in “Attack is the greatest defense”). For example, waving a sword). In other words, the defender evaluates the degree of success as a defense, but the game screen is expressed to defend against the attack by an attack, and the action specific to the defender is expressed compared to the action that became the attacker. There is no such description. Therefore, attack and defense can be performed with a single button, but in the case of defense, the same action as the attack is expressed, so the fun of the game is reduced.
[0008]
Further, in the above-described battle game, an attack is instructed using different buttons depending on the type of enemy object, or a special attack is allowed from the player only for a predetermined period according to the display operation of the enemy object. However, there is no such description in Patent Document 1 described above. That is, if a player tries to make a special attack only for a certain period of time, it is difficult for the player instructing the attack to determine a possible period or a special attack, and for each type of enemy object. The button type such as attack could not be changed.
[0009]
Therefore, an object of the present invention is to set a period during which a special attack is possible and an attack action for each type of enemy object according to the action of the enemy object, and to facilitate the operation of the battle game. Is to provide a game apparatus and a game program that make the game more exciting.

[0055]
With reference to FIGS. 6-12, the process performed by the game device 1 in the game system of this invention is demonstrated concretely.
[0056]
FIG. 6 is a flowchart showing the processing operation of the main program reaching the battle mode executed by the game apparatus 1. In FIG. 6, when the power of the game apparatus 1 is turned on, the CPU 11 of the game apparatus 1 executes a startup program stored in a boot ROM (not shown), and each unit such as the RAM 12 is initialized (step S1). ). Then, the main program is read into the RAM 12 through the DVD drive 16 and the execution of the main program is started, and the game space is represented on the CRT 3 via the image / audio processing unit 13 and the encoder 14 to start the game. .
[0057]
The player of the game apparatus 1 mainly operates the player object displayed on the CRT 3 while viewing the game image displayed on the CRT 3. The player's operation is performed by operating each input unit provided in the controller 2 as described above, and various instructions can be given to the player object according to each mode being performed in the game. . For example, when the player operates the main stick 28, the player object in the game space can be moved in an arbitrary direction. The game apparatus 1 acquires data obtained by the player operating the controller 2 in this way (step S2).
[0058]
Then, the CPU 11 of the game apparatus 1 determines whether or not the data obtained from the controller 2 is movement data obtained by the player operating the main stick 28 (step S3). The player object in the game space represented on the CRT 3 is moved via the image / audio processing unit 13 and the encoder 14 (step S4), and the process proceeds to the next step S5. When it is not movement data in the said step S3, CPU11 advances a process to following step S9.
[0059]
In step S5, the CPU 11 determines whether or not the L button 26 provided on the controller 2 is turned on. The L button 26 is used when the player selects / determines another object (for example, an enemy object of the game hero in the battle mode) with which the player object in the game space is opposed. That is, when the L button 26 is turned on by the player, one object that the player wants to face is selected / decided from a plurality of objects arranged in the game space. If the L button 26 is turned on in step S5, the CPU 11 proceeds to the next step S6. If the L button 26 is not turned on, the CPU 11 proceeds to the next step S9.
[0060]
In step S6, if the object selected / determined in step S5 is an enemy object, the CPU 11 determines whether the enemy object is within a predetermined range with respect to the player object in the game space. When the object selected / determined in step S5 is an enemy object and the enemy object is arranged within a predetermined range, the CPU 11 determines the enemy object as an opponent of the player object in the battle mode ( Step S7: Hereinafter, this process is referred to as “lock-on”), the subsequent process is shifted to the battle mode, and the process proceeds to the attack process of step S8. Details of the attack process in step S8 will be described later. On the other hand, if the object selected / determined in step S5 is not an enemy object, or if the enemy object is selected / determined and the enemy object is located outside the predetermined range, the CPU 11 proceeds to the next step S9. To proceed.
[0061]
In step S <b> 9, the CPU 11 performs normal processing in game progress other than the battle mode. As described above, the player can give various instructions to the player object according to each mode being performed in the game by operating each input unit provided in the controller 2. That is, in this step S9, the CPU 11 performs various processes according to the game mode and data from the input unit operated by the player, but detailed description thereof is omitted here.
[0062]
After the attack process in step S8 or the normal process in step S9 is completed, the CPU 11 performs a screen display process corresponding to each process, and the screen display process result is sent to the CRT 3 via the image / audio processing unit 13 and the encoder 14. It is expressed in the game space (step S10). Then, the CPU 11 determines whether or not to end the game (step S11). When the game is continued, the process returns to step S2 to continue the process. When the game is ended, the process by the main program is ended. To do.
[0063]
Before describing the detailed operation of the attack process in step S8, the “special attack” set in the game program of the present invention will be described. In the game program of the present invention, the player object is set to be able to make a special attack against the enemy object only for a predetermined period. This attack is called a “special attack”. For example, a normal attack described later is a “player object swings a sword” operation. Attacks that can cause great damage to enemy objects during the game are set such that the object turns behind the enemy object and rises and slashes. The content of such a special attack is uniquely set corresponding to the type of the enemy object, and is set for a predetermined period set in the middle of expressing a predetermined motion in which the enemy object moves (hereinafter referred to as a corresponding motion) ( Only a special attack is set to be possible). In the present embodiment, the normal attack is instructed by the player operating the B button 22 provided on the controller 2, and the special attack is instructed by operating the A button 21. In addition to the chance timing, when the player operates the A button 21, an operation different from the special attack is instructed. Here, another action is an action other than an attack on the enemy object (for example, “sword sword”) or an action to attack the enemy object by an action different from the special attack (for example, “a player object strikes the sword”). ). Hereinafter, in order to make the description more specific, the other operation will be described as an operation other than an attack on the enemy object.
[0064]
Next, the attack process executed in step S8 by the game device 1 will be specifically described. FIG. 7 is a subroutine showing the attack processing operation of step S8 executed by the game apparatus 1.
[0065]
In FIG. 7, the CPU 11 detects the type of enemy object locked on in step S7 (step S81). Then, the CPU 11 acquires data corresponding to the enemy object detected in step S81 (step S82). The main data acquired in step S82 corresponds to the various data stored in the enemy object related data area 12c described above, and the corresponding motion table is acquired as one of those data. Hereinafter, the corresponding motion table will be described. FIG. 8 is a diagram illustrating an example for explaining the corresponding motion table, and FIG. 9 is a diagram illustrating an example of the relationship between the corresponding motion set based on the corresponding motion table and the chance timing.
[0066]
In FIG. 8, in the corresponding motion table, the enemy type, the corresponding motion, the number of corresponding motion occurrence frames, the chance timing start count value s, the chance timing end count value t, and the attack at the time of success are shown for each enemy type. be written. The enemy type describes the type of enemy object, and is represented by “enemy A”, “enemy B”, “enemy C”,. The corresponding motion indicates the action of the enemy object that enables the player to perform the special attack, and for example, “motion to blow a fire”, “motion to shake a sword”, and the like are described. The number of corresponding motion generation frames describes the number of frames required to express the corresponding motion on the CRT 3. Here, the frame is a unit of an image transfer interval set on the basis of a vertical synchronization signal generated in a home television receiver or the like, for example, 1 frame = 1/60 seconds. As the chance timing start and chance timing end count values s and t, the count values at which the chance timings that occur during the expression of the corresponding motion start and end, respectively, are described. Here, the count value is a temporary variable used in the attack processing subroutine, and is counted by a special action occurrence counter stored in the enemy object related data area 12c. The successful attack describes the type of special attack performed by the player object when a special attack instruction is operated from the player at the chance timing.
[0067]
FIG. 9 shows the relationship between the corresponding motion and the chance timing when the number of corresponding motion occurrence frames is 120, the chance timing start count value s is 60, and the chance timing end count value t is 80. For the sake of specific explanation, the count value C is set to be updated every frame with the initial value C = 0. As shown in FIG. 9, the corresponding motion is finished being expressed in the CRT 3 after 120 frames have elapsed since the start. With respect to the expression of the corresponding motion, a chance timing at which a special attack is possible occurs in a period in which the count value C is 60 ≦ C <80 from the start of the corresponding motion. If this chance timing is expressed by the number of frames, the count value C is updated every frame, so that a special attack is possible for a period of 20 frames from 61 frames to 80 frames with reference to the start of the corresponding motion. On the other hand, during the period from the start of the corresponding motion to the 60th frame and the 81st frame to the end of the corresponding motion, even if the corresponding motion is expressed in the CRT 3, the special attack is set to be impossible.
[0068]
Returning to FIG. 7, after acquiring data corresponding to the enemy object in step S82, the CPU 11 performs an action process of the enemy object (step S83). This enemy object motion processing is performed by the CPU 11 based on the thinking routine data stored in the enemy object related data area 12c of the RAM 12, and using the animation data and model data of the selected enemy object, the video / audio processing unit 13 is used. And is expressed in the game space of the CRT 3 via the encoder 14.
[0069]
Next, the CPU 11 determines whether or not the operation process in step S83 corresponds to the start of the corresponding motion of the enemy object (step S84). This determination by the CPU 11 is made by referring to the corresponding motion table described above based on the type of enemy object currently locked on. Then, when it corresponds to the start of the corresponding motion, the CPU 11 initializes the special action occurrence counter stored in the enemy object related data area 12c to the counter value C = 0 (step S85), and performs the processing in the next step S86. Proceed. On the other hand, if the corresponding motion does not correspond to the start of the corresponding motion (including the case where the corresponding motion has already started and is in the middle of the corresponding motion), the CPU 11 proceeds to the next step S86 as it is.
[0070]
In step S86, the CPU 11 determines whether or not the current count value C is a chance timing start count value s ≦ C <chance timing end count value t. As the chance timing start and chance timing end count values s and t, numerical values described in the corresponding motion table are used for the corresponding motion that is currently started. If s ≦ C <t in step S86, the CPU 11 proceeds to the next step S87. If s ≦ C <t or if the corresponding motion is not expressed, the CPU 11 proceeds to the next step S90. Proceed.
[0071]
The CPU 11 performs an action icon display process in step S87, and performs a normal icon display process in step S90. Hereinafter, an example of a game image represented on the CRT 3 in each icon display process will be described with reference to FIGS. 10 is an example of a game image represented on the CRT 3 in the normal mode, and FIG. 11 is an example of a game image represented on the CRT 3 when the normal icon display process is performed in the battle mode. Is an example of a game image represented on the CRT 3 when action icon display processing is performed in the battle mode.
[0072]
In FIG. 10, for example, in the normal mode in step S9, in the game image represented on the CRT 3, other objects such as the player object PO, the enemy object EO, and background objects (not shown) are displayed as the game progresses. The icon object IO is further expressed. The icon object IO is expressed as an icon so that, for example, the A button 21, the B button 22, the X button 23, the Y button 24, and the R button 25 in the input unit of the controller 2 can be easily viewed by the player on the CRT 3. It is an object. The icon object IO displays an instruction given to the game apparatus 1 when each input unit represented by an icon is operated by the player. In the example shown in FIG. 10, an instruction “Kake” is given by the player operating the A button 21, an instruction “Return” is given by operating the B button 22, and an instruction “squatting” is given by operating the R button 25. It is expressed that it is given to the game apparatus 1. For example, “KET” is an instruction to determine an option such as the currently selected command, “RETURN” is an instruction to return to the previous process without determining the above option, and “Squat” is to the player object PO. This indicates that an instruction to perform a squatting operation on the game screen is given.
[0073]
In FIG. 11, the game image displayed on CRT3 by the normal icon display process of the said step S90 is shown. In this process, as described above, the game mode is shifted to the battle mode, and the enemy object EO is locked on. Therefore, the player object POf indicating the battle mode state and the enemy object EOf are expressed on the CRT 3, and the enemy object EOf is expressed with the lock-on mark RM indicating that the player is locked on. For example, the player object POf indicating the battle mode state represents an image of the player object as if an item (for example, a sword) that attacks the enemy object Eof is taken out. In addition, an icon object IOf indicating the battle mode state is expressed in CRT3. The icon object IIf is represented as an icon so that the player can easily see the same input unit as the icon object IO in the normal mode, but the instruction content given to the game apparatus 1 is different. Specifically, it is expressed that an instruction to “get” is given to the game apparatus 1 by the operation of the A button 21 by the player, and an instruction to attack using the “sword” item by the operation of the B button 22. ing. The “sword” is an instruction to cause the player object POf to move the currently picked item (sword) without attacking the enemy object EOf, and the “sword” item indicates that the player object POf is the enemy object EOf. On the other hand, it is an instruction to cause an attack (hereinafter referred to as a normal attack) by a “sword sword” operation. For example, when the player operates the A button 21 to perform a special attack at the timing when the normal icon display processing is performed, the special attack is not executed (special attack failure), and the item (sword that is currently taken out) ).
[0074]
In FIG. 12, the game image displayed on CRT3 by the action icon display process of the said step S87 is shown. In this process, as described above, the game mode is shifted to the battle mode, and the enemy object EO is locked on. Furthermore, the enemy object EO is in a period of chance timing during which the corresponding motion is being performed and a special attack is possible. Therefore, the player object POf indicating the battle mode and the enemy object EOc indicating the corresponding motion are expressed in the CRT 3, and the enemy object EOc is expressed with the lock-on mark RM indicating that the player is locked on. For example, when the enemy object EO is “enemy A” in the corresponding motion table shown in FIG. 8, the enemy object EOc represents “motion that blows fire”. Further, an icon object IOc indicating the chance timing state is expressed in CRT3. The icon object IOc is represented as an icon so that the player can easily see the same input unit as the icon object IO in the normal mode, but the instruction content given to the game apparatus 1 is different. Specifically, it is expressed that the game device 1 is given an instruction of “special attack” by the operation of the A button 21 by the player and an instruction of attacking by using the “sword” item by the operation of the B button 22. Has been. The player can perform a “special attack” on the enemy object EOc by operating the A button 21 during this chance timing period. For example, when the player gives a “special attack” instruction, the player object POf causes “the player object to make a large jump and slash vertically” or “the player object wraps behind the enemy object and slashes and rotates”. A special attack capable of giving a large damage to the enemy object EOc as the game progresses is expressed based on the corresponding motion table.
[0075]
Returning to FIG. 7, the CPU 11 performs action icon display processing for displaying the icon object IOc and the like in step S <b> 87, and expresses each object in the game space of the CRT 3 via the image / audio processing unit 13 and the encoder 14. Next, the CPU 11 determines whether or not the A button 21 provided on the controller 2 is turned on by the operation of the player (step S88). When the A button 21 is turned on, the CPU 11 determines that a special attack instruction has been given from the player during the chance timing period, and performs a special attack process based on the corresponding motion table (step S89). The process proceeds to S93. The special attack processing is performed based on the description of the attack at the time of success of the corresponding motion table stored in the enemy object related data area 12c of the RAM 12 by the CPU 11, and the special action stored and selected in the player object related data area 12b. The data, the animation data of the player object, and the model data are used to represent the game space of the CRT 3 via the image / audio processing unit 13 and the encoder 14. On the other hand, if the A button 21 is not turned on in step S88, the CPU 11 advances the process to the next step S93.
[0076]
On the other hand, the CPU 11 performs a normal icon display process for displaying the icon object IOf and the like in step S90, and expresses each object in the game space of the CRT 3 via the image / audio processing unit 13 and the encoder. Next, the CPU 11 determines whether or not the A button 21 provided on the controller 2 is turned on by the operation of the player (step S91). When the A button 21 is turned on, the CPU 11 determines that the normal processing instruction has been given from the player (special attack failure) because it is outside the chance timing period, and performs normal processing (step S92). The process proceeds to step S93. This normal process is performed by the CPU 11 using the action data stored in the player object related data area 12b of the RAM 12 and the animation data and model data of the player object, and the CRT 3 game via the audio / video processing unit 13 and the encoder 14. Expressed in space. For example, in the battle mode shown in FIG. 11, as the normal process, the action of the player object POf “sword the sword” is expressed in the game space of the CRT 3. On the other hand, if the A button 21 is not turned on in step S91, the CPU 11 advances the process to the next step S93.
[0077]
In step S <b> 93, the CPU 11 determines whether another attack button provided on the controller 2 is turned on by the player's operation. This “other attack button” corresponds to the B button 22 in which the item “sword” is displayed in the example of FIG. 11 or FIG. 12, and is an input unit in which the normal attack is currently set. When the other attack button is turned on, the CPU 11 determines that a normal attack instruction has been given from the player, performs a normal attack process (step S94), and proceeds to the next step S95. In this normal attack process, the CPU 11 uses the action data stored in the player object related data area 12b of the RAM 12 and selected, the animation data and model data of the player object, and the CRT 3 via the image / audio processing unit 13 and the encoder 14. Expressed in the game space. For example, in the battle mode shown in FIG. 11 or FIG. 12, as the normal attack process, the player object POf attacks the enemy object EOf or EOC by expressing the action of “swinging the sword” in the game space of CRT3. . On the other hand, if the other attack button is not turned on in step S93, the CPU 11 proceeds to the next step S95 as it is.
[0078]
In step S95, the CPU 11 determines whether or not the corresponding motion performed by the enemy object has ended. If the corresponding motion is continuously expressed, the CPU 11 increments the counter value C of the special action occurrence counter set in the enemy object related data area 12c of the RAM 12 (step S96), and proceeds to the next step S97. Proceed with the process. On the other hand, when the corresponding motion is not currently expressed or when the corresponding motion is completed, the CPU 11 proceeds to the next step S97 as it is.
[0079]
In step S97, the CPU 11 determines whether or not the attack on the enemy object has ended. The CPU 11 determines the end of the attack when the player object or the enemy object becomes unable to attack, or when the battle mode is ended by an instruction from the player. Then, when continuing the attack (that is, continuing the battle mode), the CPU 11 returns to step S83 to continue the process in the battle mode. When ending the attack, the CPU 11 ends the battle mode, and the attack processing program The process by the subroutine is terminated.
[0080]
As described above, the game device of the present invention uses the input unit (A button 21) used for instructions other than the attack for the special attack instruction only during the above-described chance timing by executing the game program. it can. Further, when this special attack is instructed, it is possible to express an attack action peculiar to the player object, and since the operation is easy, the battle game can be made more exciting.
[0081]
In the corresponding motion table described above, an example in which one corresponding motion is set for each type of enemy object is shown. However, a plurality of corresponding motions may be set for one type of enemy object. It doesn't matter. When a plurality of corresponding motions are set, the CPU 11 selects and starts a predetermined corresponding motion based on the enemy object thinking routine data. Next, the CPU 11 initializes the counter value C in step S85 in accordance with the start of the selected corresponding motion, and performs the attack process shown in FIG. Then, after the corresponding motion is completed, the battle mode is continued, and when another corresponding motion is started with the same enemy object, the counter value C is similarly initialized in step S85, as shown in FIG. If the attack processing shown is continued, the CPU 11 can perform the attack processing for each of the plurality of corresponding motions.
[0082]
In the above description, the input unit that gives each attack instruction has been specifically described. However, the input unit that gives each attack instruction is not limited to these. It goes without saying that any input unit can be realized by assigning instruction contents to the input units provided in the game device for executing the game program of the present invention.
[0083]
In the above description, a stationary game device is provided in the game system. However, a game device to which the present invention can be applied may not be a stationary game device. For example, even in a portable game device, the present invention can be applied using a plurality of input units provided in the game device, and the computer system includes a general display unit. In addition, the present invention can be applied.
