The output signal may include an audio signal. The display device 20 displays an application screen or the like based on the video signal. If the output signal includes an audio signal, the audio may also be output.

The storage device 14 is a storage device included in a typical game machine or electronic device, and includes a RAM which is a volatile memory and a ROM which is a nonvolatile memory. Storage device 14 may also include external memory. For example, the storage device 14 stores game applications. A game application includes a game program for executing a game and various data referred to when executing the game program. The game program is started in response to a user's operation on the electronic device 10, and is executed on an operating system (OS) installed in the electronic device 10 in advance.

In one example, storage device 14 includes main storage and auxiliary storage. The main storage device is a volatile storage medium that allows information to be read and written at high speed, and is used as a storage area and a work area when the processor 11 processes information. The auxiliary storage device stores various programs and data used by the processor 11 when executing each program. The auxiliary storage device is, for example, a hard disk device, but it may be any nonvolatile storage or nonvolatile memory that can store information, and may be removable.

For example, the communication device 15 performs mobile communication or wireless communication such as wireless LAN, and connects to a network. In one example, communication device 15 downloads a program from a server and stores it in storage device 14 . However, the communication device 15 may perform wired communication using an Ethernet (registered trademark) cable or the like. When not transmitting or receiving data with another computer, the electronic device 10 does not need to include the communication device 15.

FIG. 2 shows an example of a functional block diagram of the game system 1 according to an embodiment of the present invention. The system 1 includes an input section 31, a display section 32, and a game control section 33. The game control section 33 includes a player character control section 330, an enemy character control section 331, an attack determination section 332, a difficulty level determination section 333, and a suppression time management section 334. In this embodiment, these functions are realized by the processor 11 of the electronic device 10 executing a program and operating in cooperation with the display device 20. For example, the program to be executed is a game program stored in the storage device 14 or received via the communication device 15. In this way, various functions are realized by reading a program, so that another part may have part or all of one part (function). These functions may also be realized by hardware by configuring an electronic circuit or the like to realize some or all of the functions.

The input unit 31 is configured using the input device 12 and receives input from a user to the electronic device 10. The electronic device 10 receives user input through the input unit 31 .

The display unit 32 displays a game screen including a game field on the display device 20 based on the video signal output from the output device 13 of the electronic device 10 .

The game control unit 33 performs basic control in executing the game of this embodiment. The game control section 33 stores information necessary for progressing the game such as parameters and game states, and also stores the states of the player character control section 330, enemy character control section 331, difficulty level determination section 333, and suppression time management section 334. Monitor and control.

FIG. 3 is a diagram showing an example of a game screen. The game control unit 33 sets a game field as a virtual space for progressing the game, and displays a part of the field as a game screen 40 on the display unit 32. A player character 41 and an enemy character 42 are arranged within the game field. The player character 41 is an object that acts within the game field based on the player's input, and the enemy character is a non-player object that acts within the field regardless of the player's input.

The player character control section 330 controls the player character 41 based on input by the player via the input section 31. The player character 41 executes actions such as moving, turning, attacking, evading, and defending. The enemy character control unit 331 controls the enemy character based on a predetermined action pattern without depending on the player's input. The predetermined action pattern is, for example, movement, turning, attack, movement, movement, attack, which is determined in advance, and the actions of the enemy character are executed in this order. Furthermore, a plurality of action patterns may be prepared and one of them may be applied based on the game state. For example, prepare a behavior pattern before discovering the player character and a behavior pattern after discovering the player character, and if the player character is outside a predetermined range from the coordinates of the enemy character, the behavior before discovering the player character. Using a pattern, when the player character is within a predetermined range, the behavior pattern after discovering the player character can be used. Furthermore, an action pattern may be prepared depending on the remaining hit points (physical strength) of the enemy character. A plurality of action patterns may be prepared for each game state, and may be selected and used at random, for example.

The attack determination unit 332 determines whether the attack by the player character 41 against the enemy character 42 was successful, and whether the attack by the enemy character 42 against the player character 41 was successful. Whether or not the attack is successful can be determined by determining whether or not the characters collide with each other. For example, whether or not the attack of the enemy character 42 was successful is determined based on information such as the placement of the player character and the placement of the enemy character, based on whether the part of the arm used by the enemy character for the attack collided with the player character. This can be done using collision detection. Whether or not the attack of the player character 41 has been successful can be determined by determining whether or not the player character's weapon has collided with the enemy character based on the arrangement of the player character, the arrangement of the enemy character, and the like.

The difficulty level determination unit 333 determines the game difficulty level. In this embodiment, the game difficulty level is determined based on the player's difficulty level. The level of difficulty changes during the course of the game based on the estimated proficiency level of the player's actions. The game difficulty level is determined based on the player's difficulty level, and can dynamically change while the game is in progress according to fluctuations in the player's difficulty level. As another embodiment, the game difficulty level may be determined by the player before the game starts, and may not change while the game is in progress.

The suppression time management unit 334 manages the start and end of the suppression time. When the game control unit 33 instructs the start of the suppression time, the suppression time management unit 334 starts the suppression time and also starts a suppression time timer for measuring elapsed time. Then, a suppression time management process is executed to continuously monitor whether the suppression time end condition is satisfied. In this embodiment, the suppression time end condition is that a predetermined period determined based on the game difficulty expires, and a predetermined action by the enemy character is executed based on the probability of occurrence determined based on the game difficulty. occurs, and the player character performs a predetermined action based on player input. Whether or not the predetermined period has expired can be determined based on whether the suppression time timer has exceeded the predetermined time.

Further, the player character 41 and the enemy character 42 have parameters, and the parameters are set in advance by a game administrator or the like. For example, parameters include level, attack power, defense power, hit points, etc. The player character 41 and the enemy character may be a plurality of characters.

Next, an example of the game of this embodiment will be briefly described. The game of this embodiment is an action game in which, when a player character operated by a player encounters an enemy character on the game field, the player character engages in battle with the enemy character. The game control section 33 displays a game screen including a game field on the display section 32. The game screen includes, at least at the start of the game, the player character and the surrounding game field where the player character is placed at the start of the game. Then, when the player character moves within the game field based on the player's input and encounters an enemy character, a battle begins.

For example, when the enemy character discovers the player character, the enemy character starts executing an action pattern for battle and attacks the player character. The player character attacks the enemy character while defending or avoiding attacks from the enemy character.

If the attack by the enemy character is successful, damage is given to the player character and the hit points are reduced. When the player character's attack is successful, the enemy character's hit points are reduced. The game ends when the player character's hit points reach 0 due to an attack by the enemy character. When the enemy character's hit points reach 0 due to an attack by the player character, the player character wins. The game may end when the player character wins, or the game may be continued to fight another enemy.

Next, information processing executed in the game system 1 according to an embodiment of the present invention will be explained using the flowcharts shown in FIGS. 4 to 7. Note that although a game machine is used as the electronic device 10 in this embodiment, the frame rate of the game machine is generally set to 30 fps, 60 fps, or the like. Preferably, the electronic device 10 executes the process at regular intervals in accordance with the frame rate. Therefore, for example, elapsed time is determined from the frame rate and the number of elapsed frames.

When the processor 11 executes the program for the game stored in the storage device 14 of the electronic device 10, the display unit 32 displays a game screen including a game field as shown in FIG. 3 (S401). Next, the game control unit 33 updates the game state information (S402). The game state information includes player character information about the player character 41 operated by the player, information about the enemy character 42 which is a non-player character, game parameter information such as weak point and difficulty level, suppression time state, and the like. The player character information and enemy character information include each character's placement, actions, attack power, defense power, hit points, and the like. The character arrangement includes information about the character's coordinates, posture, direction, etc. within the game field. Character actions include movement, turning, attack, avoidance, defense, and combinations thereof. For example, a character may turn and perform an action at the same time.

When the game is started, the game control unit 33 and the like continuously execute the processes shown in FIGS. 5 to 7 and update the game state information. Although not shown, the player character control process and the enemy character control process by the player character control section 330 and the enemy character control section 331 are also started and are continuously executed in parallel. In the player character control process, the player character performs actions in the game field based on player input input via the input unit 31, and player character information is updated. For example, the player character is moved forward within the game field by a player input instructing forward movement, and the coordinates of the player character are calculated and updated.

Since the enemy character is a non-player character, its actions are determined and executed by the enemy character control unit 331, regardless of player input. When the enemy character takes action, enemy character information is calculated and updated. As described above, the enemy character's actions include, for example, a predetermined action pattern that includes a plurality of actions. Furthermore, the behavior pattern may be selected based on the game difficulty level. For example, a behavior pattern used when the game difficulty level is low is configured to have few attacks, and is structured so that complex actions such as turning and attacking are not performed at the same time, and a behavior pattern used when the game difficulty level is high. attacks are more frequent and are configured to perform more complex actions.

The game control unit 33 updates the game screen based on the updated game state information and displays it on the display unit 32 (S404). The game control unit 33 determines whether or not the game is in a state to end based on the game end input by the player or the game state (S406), and ends the game if it is determined that the game is in a state to end. If not, the process returns to updating the game state (S402). For example, when the hit point of the player character in the game state information becomes 0, it is determined that the game is in a state to be ended. The electronic device 10 repeatedly executes S402 to S406 until it is determined that the game is in a state to end.

Next, enemy character attack processing will be explained using FIG. First, the enemy character control unit 331 executes an enemy character attack against the player character (S501).

The player can cause the player character to take an evasive action by inputting an input to avoid the attack in response to the enemy character's attack being executed by the enemy character control unit 331. For example, when the player inputs a direction input instructing a direction and an avoidance input instructing avoidance through the input unit 31, the player character control unit 330 turns the player character in the direction specified by the direction input. while executing the avoidance process. If the input for avoidance by the player is made at the appropriate timing and in the appropriate direction, the player character will be moved by the player character avoidance processing by the player character control unit, and the attack by the enemy character will not collide with the player character. Therefore, the attack by the enemy character is not successful in S502.

When the enemy character attack is executed (S501), the game control unit 33 determines whether or not the player character control unit 330 has caused the player character to successfully evade by performing a predetermined evasive action based on the player input (S502). . In this embodiment, the predetermined avoidance motion is an avoidance motion in a predetermined direction. For example, if the player inputs movement to the side of the enemy character and presses an input button assigned for evasion at the appropriate time, the enemy character can It is determined that the attack has been successfully avoided. If there is a movement input in the direction away from the enemy character, even if the avoidance is successful, it will not be determined that the avoidance is due to a predetermined avoidance action. Furthermore, if the timing of the player's input is inappropriate, the enemy character's attack cannot be appropriately avoided, and it is not determined that the avoidance has been successful.

FIG. 3 shows a game screen when performing a predetermined avoidance action. FIG. 3A shows the enemy character 42 swinging his arms toward the player character 41 and attacking. In FIG. 3B, in response to an attack by the enemy character 42, the player performs a predetermined avoidance action by the player inputting movement to the side of the enemy character 42 and inputting avoidance at appropriate timings. It shows the situation. FIG. 3C shows how the player character 41 successfully avoids the attack of the enemy character 42 by performing a predetermined evasive action, and also moves around to the side of the enemy character, that is, into the enemy character's blind spot. It shows.

As shown in FIG. 3, the player character's avoidance action may begin before the enemy character's attack action ends. In this embodiment, enemy character control and player character control are executed in parallel, so it is possible to control one without waiting for the other to end.

As a modified example, the predetermined avoidance movement is not limited to avoidance in a predetermined direction, but any avoidance movement that is made at the appropriate timing to avoid the attack of the enemy character can be considered as the predetermined avoidance movement. You can also do that.

When the game control unit 33 determines that a predetermined avoidance action has been performed, the game control unit 33 instructs the suppression time management unit 334 to start the suppression time, and the suppression time management unit 334 starts the suppression time (S504). The suppression time management unit 334 updates the suppression time state information to indicate that the suppression time is in progress, and starts a suppression time timer. The suppression time ends when a termination condition described later is satisfied. One of the termination conditions is that a predetermined period of time has elapsed since the start of the suppression time. This period is determined based on the level of difficulty.

During the suppression time, the actions of the enemy character are restricted. The actions of the enemy character can be restricted by changing the action pattern of the enemy character. In this embodiment, the action pattern of the enemy character is changed (S506). During the suppression time, the enemy character does not attack the player character, and does not move or turn so that the player character's attack is likely to be successful. For example, the enemy character control unit 331 refers to the suppression time state information, and if it is in the suppression time state (during the suppression time), the enemy character control unit 331 performs an attack or defense such as movement, attack, or turning included in a predetermined action pattern. Behavior patterns can be changed by replacing all information indicating related behaviors with behaviors such as waiting. In addition, a behavior pattern for the normal state that is not the suppression time and a behavior pattern for the suppression time state are prepared, and the behavior pattern for the normal state is normally used, and when the suppression time starts, the behavior pattern for the suppression time state is prepared. You may also use In another embodiment, instead of or in addition to changing the action pattern, the enemy character's actions may be slowed down.

When actually fighting a powerful monster, it is a dangerous act for a small human to attack from the front, and even if the attack is successful, it is considered difficult to inflict sufficient damage. It is thought to be effective to sneak past the monster's attack and sneak into an unfavorable spot, such as a blind spot, before attacking. Therefore, in a game where the player character can fight head-on on equal terms with the enemy character, even if high-definition images are displayed to realistically represent the enemy character's strength, the player will not be able to see how powerful the enemy character is. It is impossible to fully feel it with reality.

In this embodiment, the suppression time state can be established by successfully performing a predetermined evasive action against an attack by an enemy character. Since the actions of the enemy character are restricted during the suppression time, it is an advantageous time for the player to make a successful attack. Here, the predetermined evasive action is an evasive action to the side, which is a disadvantageous place such as a blind spot for the enemy character. That is, the player character can create an advantageous attack situation by dodging the attack of the enemy character and moving around to the blind spot, and can make an effective attack against the powerful enemy character within a predetermined time.

By understanding that it is more effective to sneak into the enemy character's blind spot and then attack, rather than attacking the enemy character head-on, the player can realize that the enemy character they are facing is a powerful monster. You can feel it with realism. By restricting the actions of the enemy character, it is possible to express that the enemy character is unable to take sufficient attacking actions due to movement of the player character to a location disadvantageous to the enemy character. Furthermore, in the normal state (non-suppression time state), compared to attacking the enemy character from the front, if you increase the damage to the enemy character by attacking during the suppression time, you can give a greater sense of reality. .

If it is not determined that the player character has executed a predetermined avoidance process in response to the attack by the enemy character, the game control unit 33 determines whether or not the attack by the enemy character was successful (S508).

If the player inputs an input for evasion, but it is not determined that the evasion has been performed because the evasion was not in the specified direction or the timing was inappropriate, the enemy character's attack Since there is a possibility of success, a determination is made as to whether or not the enemy character's attack was successful. Even if the player does not make any input in response to an enemy character's attack, there is a possibility that the attack will be successful. Also, if the enemy character's attack is executed in an area where the player character cannot reach the attack, the attack will not be successful. If it is determined that the attack by the enemy character was not successful, the attack processing by the enemy character ends.

On the other hand, if it is determined that the attack by the enemy character was successful, damage is applied to the player character (S510). Specifically, the hit points of the player character are reduced by a predetermined amount. The amount of reduction is determined by parameters such as the enemy character's attack power value and the player character's defense power value.

Next, the degree of weakness of the player character is increased (S512). Here, the weak point indicates the player's weak point in the action, and the higher the player is estimated to be weak at operating the player character to perform actions such as attack and evasion, the higher the value will be. The more it is estimated, the lower the value. If the enemy character's attack is successful, it is assumed that the player is not good at actions, so the degree of weakness is increased, and if the player character's attack is successful, it is presumed that the player is good at actions, so the degree of weakness is increased. reduce For example, in the initial state, the weak point is set to the minimum value of 0, and when the player character is attacked by an enemy character, the weak point is increased by 10, while when the player character successfully attacks, the weak point is decreased by 3.

In S514, the difficulty level of the game is determined based on the difficulty level. For example, if the difficulty level is 0 to 20, it will be set to difficulty level 3, which is high difficulty, if the difficulty level is 21 to 40, it will be set to difficulty level 2, which is medium difficulty, and if the difficulty level is 41 or higher, it will be set to difficulty level 2. In this case, the difficulty level is set to 1, which is a low difficulty level. In this way, the game difficulty level is determined based on the player's difficulty level, so it is changed during the game in accordance with changes in the player's difficulty level. The difficulty level, which indicates that the player is not good at actions based on player input, is changed sequentially during the game, and the difficulty level of the game is changed based on this, thereby providing a game difficulty level that matches the player's skill level. It becomes possible to do so. Once the game difficulty level is determined, the enemy character attack process ends.

Next, the player character attack process will be explained using FIG. 6. In the player character attack process, processing is performed when the player inputs an input to attack the enemy character via the input unit 31. First, based on player input, the player character control unit 330 executes an attack on the enemy character by the player character (S601), and the game control unit 33 determines whether the attack on the enemy character was successful (S602). ).

If it is determined that the attack by the player character is successful, damage is applied to the enemy character (S604). Specifically, the enemy character's hit points are reduced by a predetermined amount. Then, the degree of weakness of the player character is reduced (S606). If the player character's attack is successful, it is presumed that the player character is good at actions, so the degree of weakness is reduced. Next, the difficulty level of the game is determined based on this difficulty level (S608).

In S610, the game control unit 33 determines whether or not the suppression time is in progress based on the suppression time state information, and if it is not within the suppression time, ends the player character attack process, and if it is within the suppression time, the enemy character The control unit is caused to execute an enemy character reaction action (S612). In this embodiment, an action indicating that the enemy character has received damage is displayed on the display unit 32.

By causing the enemy character reaction action to be executed only when the player character successfully attacks the enemy character within the suppression time, it is possible to make the player recognize that the suppression time is a special time. Thereby, it is possible to provide the player with the pleasure of discovering the rules by himself while playing the game, without providing a tutorial or the like to explain the basic rules of the game before the player starts the game.

In the present embodiment, the enemy character's action pattern is changed during the suppression time, creating a state advantageous to the player. The suppression time is a special time when the enemy character performs a reaction, and the suppression time is an advantageous time for the player because the player notices that the enemy character does not take actions such as attacks. , it is possible to encourage the user to recognize that it is necessary to perform a predetermined avoidance in order to create a restrained time state. The reward for performing a given avoidance can also be specified.

In S612, it is determined whether the enemy character executes a counter attack. It is determined whether or not to execute the counter attack based on a predetermined probability of occurrence. Here, it is assumed that the probability of a counter attack occurring is determined based on the game difficulty level. For example, the probability of occurrence can be set to 50% for high difficulty, 30% for medium difficulty, and 0% for low difficulty. Furthermore, it can also be based on the enemy character's remaining hit points. According to one embodiment, by multiplying the standard occurrence probability based on the remaining HP of the enemy character by a coefficient corresponding to the game difficulty level, it is possible to calculate the occurrence probability according to the game difficulty level. For example, when the remaining hit points (HP) is 25% > HP ≧ 0%, the standard occurrence probability is 50%, when 75% > HP ≧ 25%, the standard occurrence probability is 30%, and when 100% > HP ≧ 75%, the standard occurrence probability is 50%. The probability is 20%, the coefficient for high difficulty is 1.0, the coefficient for medium difficulty is 0.8, and the coefficient for low difficulty is 0.5. In this case, when the remaining hit points (HP) is 25%>HP≧0%, the probability of occurrence is 50 x 1.0 = 50% on high difficulty, and 50 x 0.8 on medium difficulty. = 40%, and at low difficulty level it is 50 x 0.5 = 25%. The lower the probability of a counter attack occurring, the lower the difficulty level of the game.

If it is determined that a counter attack will not occur, the player character attack process ends. If it is determined that a counter attack will occur, the enemy character attack process described using FIG. 5 is started in S616, and the player character attack process is ended. In this embodiment, as will be described later, the suppression time ends when a counter attack occurs.

Next, the suppression time management control will be explained using FIG. 7. As described above, when the player character successfully avoids an enemy character attack by executing a predetermined avoidance action based on the player's input, the suppression time enters and the suppression time timer is started. The suppression time ends when at least one of the following conditions is satisfied: a timer expires, a predetermined action by the enemy character occurs, and a predetermined action is performed by the player character based on player input. .

In this embodiment, the expiration time of the suppression timer is determined based on the game difficulty level. For example, the time can be set to 0.7 seconds for a high difficulty level, 0.9 seconds for a medium difficulty level, and 1.1 seconds for a low difficulty level. The longer the suppression time is, the longer a state advantageous to the player is maintained, and therefore the difficulty of the game can be lowered. A predetermined action by the enemy character can be a counter attack. As mentioned above, the probability that a counter attack will occur can also be determined based on the game difficulty level.

In this embodiment, the game difficulty level is determined based on the level of difficulty. Since the degree of weakness changes from time to time based on the success of attacks by the player and the success of attacks by enemy characters, the skill of the player can be expressed in real time. By determining the game difficulty level based on this difficulty level, and determining the suppression time and counter probability based on the game difficulty level, it is possible to provide a game with a difficulty level that corresponds to the player's skill in real time.

In this embodiment, the predetermined action by the player character to end the suppression time is, for example, an avoidance action. The suppression time is an advantageous time for the player to attack, and the player can be made to understand that the action of evasion is inappropriate during the suppression time when the enemy character's attack is limited.

If it is determined that the suppression time end condition is not satisfied (S701), the suppression time is continued until the suppression time end condition is satisfied. On the other hand, if any one of the suppression time end conditions is satisfied, the action pattern of the enemy character is changed (S702), the suppression time state information is changed to information indicating a non-suppression time state, and the suppression time is ended. (S704). Here, the behavior pattern is changed by returning the behavior pattern that was changed to limit the behavior of the enemy character back to the normal behavior pattern after the suppression time has started. For example, in S504, the behavior pattern is changed by returning all information that was replaced with behavior such as standby to information indicating behavior such as movement, attack, and turning, which is included in the predetermined behavior pattern.

In the processing or operation described above, as long as there is no contradiction in the processing or operation, such as using data that should not be available at that step in a certain step, the processing or operation can be freely performed. Can be changed. Further, each of the embodiments described above is an illustration for explaining the present invention, and the present invention is not limited to these embodiments. The present invention can be implemented in various forms without departing from the gist thereof.
