FIG. 2 shows an example of a functional block diagram of the game system 1 according to the embodiment of the present invention. The system 1 includes an input unit 31, a display unit 32, and a game control unit 33. The game control unit 33 includes a player character control unit 330, an enemy character control unit 331, an attack determination unit 332, a difficulty level determination unit 333, and a suppression time management unit 334. In the present 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 executed program is a game program stored in the storage device 14 or received via the communication device 15. As described above, since various functions are realized by reading programs, some or all of one part (function) may be included in another part. These functions may also be realized by hardware by configuring an electronic circuit or the like for realizing a part or all of each function.

The input unit 31 is configured using the input device 12, and receives an input from the user to the electronic device 10. The electronic device 10 receives a 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 for executing the game of this embodiment. The game control unit 33 stores information necessary for the progress of the game, such as parameters and game states, and stores the states of the player character control unit 330, the enemy character control unit 331, the difficulty level determination unit 333, and the suppression time management unit 334. Monitor and control.

FIG. 3 is a diagram showing an example of the 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 game field on the display unit 32 as a game screen 40. A player character 41 and an enemy character 42 are arranged in the game field. The player character 41 is an object that acts in the game field based on the player's input, and the enemy character is a non-player object that acts in the field regardless of the player's input.

The player character control section 330 controls the player character 41 based on the input by the player via the input section 31. The player character 41 performs actions such as moving, turning, attacking, avoiding, and defending. The enemy character control unit 331 controls the enemy character based on a predetermined action pattern without depending on the input by the player. As the predetermined action pattern, for example, the action patterns of moving, turning, attacking, moving, moving, and attacking are determined in advance, and the actions of the enemy character are executed in this order. Alternatively, a plurality of action patterns may be prepared and any one of them may be applied based on the game state. For example, an action pattern before the player character is found and an action pattern after the player character is found are prepared. If the player character is outside the predetermined range from the coordinates of the enemy character, the action before the player character is found. By using a pattern, it is possible to use an action pattern after the player character is found when it is within a predetermined range. Also, an action pattern corresponding to the remaining hit points (physical strength value) of the enemy character may be prepared. A plurality of action patterns may be prepared for each game state, and may be randomly selected and used, for example.

The attack determination unit 332 determines whether the attack on the enemy character 42 by the player character 41 has succeeded, and whether the attack on the player character 41 by the enemy character 42 has succeeded. The determination as to whether or not the attack is successful can be performed by determining the collision between the characters. For example, whether or not the attack of the enemy character 42 has succeeded is determined based on information such as the arrangement of the player character and the arrangement of the enemy character, and whether or not the arm portion used by the enemy character for the attack has collided with the player character. It can be performed by determining the collision. Whether or not the attack of the player character 41 has succeeded can be determined by a collision determination as to whether or not the weapon of the player character has collided with the enemy character based on the arrangement of the player character and the arrangement of the enemy character.

The difficulty level determination unit 333 determines the game difficulty level. In the present embodiment, the game difficulty level is determined based on the player's difficulty level. The weakness varies depending on the estimation of the skill level of the action of the player during the progress of the game. The game difficulty level is determined based on the weakness level, and can dynamically change during the progress of the game in accordance with the fluctuation of the weakness level. As another embodiment, the game difficulty level may be determined by the player before the game starts and may not change during the game progress.

The suppression time management unit 334 manages the start and end of the suppression time. When the start of the suppression time is instructed by the game control unit 33, the suppression time management unit 334 starts the suppression time and also starts the suppression time timer for measuring the elapsed time. Then, a suppression time management process for continuously monitoring whether or not the suppression time end condition is satisfied is executed. In the present embodiment, the suppression time end condition is that the predetermined period determined based on the game difficulty level expires, and the predetermined action by the enemy character executed based on the occurrence probability determined based on the game difficulty level. Is generated and a predetermined action is performed by the player character based on the player input, and at least one of them is satisfied. Whether or not the predetermined period has expired can be determined based on whether or not the suppression time timer has exceeded the predetermined time.

In addition, the player character 41 and the enemy character 42 have parameters, and the parameters are preset by the game manager or the like. For example, the parameters include level, attack power, defense power, hit points, and the like. 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 the present embodiment is an action game in which when a player character operated by the player encounters an enemy character in the game field, the player character battles with the enemy character. The game control unit 33 displays a game screen including a game field on the display unit 32. At least at the start of the game, the game screen includes the player character and the peripheral game field in which the player character is arranged at the start of the game. Then, based on the input by the player, when the player character moves in the game field and encounters an enemy character, a battle is started.

For example, when the enemy character finds 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 protecting or avoiding the attack from the enemy character.

When the attack by the enemy character is successful, the player character is damaged and the hit points are reduced. When the player character successfully attacks, the hit points of the enemy character are reduced. The game ends when the hit points of the player character reach 0 due to the attack by the enemy character. When the hit point of the enemy character reaches 0 due to the attack by the player character, the player character wins. The game may be ended by the victory of the player character, or the game may be continued in order to battle with a further enemy.

Next, information processing executed in the game system 1 according to the embodiment of the present invention will be described using the flowcharts shown in FIGS. Although a game machine is used as the electronic device 10 in this embodiment, a frame rate such as 30 fps or 60 fps is generally set for the game machine. The electronic device 10 preferably executes processing at fixed time intervals corresponding to the frame rate. Therefore, for example, the 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 the game screen including the 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 that is a non-player character, game parameter information such as difficulty level, difficulty level, and suppression time state. The player character information and the enemy character information include each character's placement, action, attack power, defense power, hit points, and the like. The placement of the character includes information about the character's coordinates, posture, direction, etc. in the game field. The character's actions include moving, turning, attacking, evading, defending, and combinations thereof. For example, the character may make a turn and an action simultaneously.

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

Since the enemy character is a non-player character, its action is determined and executed by the enemy character control unit 331 regardless of the player's input. When the enemy character acts, the enemy character information is calculated and updated. As described above, the action of the enemy character executes, for example, a predetermined action pattern including a plurality of actions. Further, the action pattern may be selected based on the game difficulty level. For example, the action pattern used when the game difficulty level is low has less attacks, and is configured so that complex actions, such as turning and attack, are not executed at the same time, and the action pattern used when the game difficulty level is high. Are frequently attacked 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 the game based on the game end input by the player or the game state (S406), and if it is determined to be in the state to end the game, ends the game. If not, the process returns to the process of 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 finished state. The electronic device 10 repeatedly executes S402 to S406 until it is determined that the game is finished.

Next, the enemy character attack processing will be described with reference to FIG. First, the enemy character control unit 331 executes an enemy character attack on the player character (S501).

In response to the attack performed by the enemy character by the enemy character control unit 331, the player makes an input for avoiding the attack, thereby allowing the player character to perform the avoiding motion. For example, when a direction input indicating any direction by the player and an avoidance input indicating an avoidance are input via the input unit 31, the player character control unit 330 turns the player character in the direction instructed by the direction input. While executing the process to avoid. If an input for avoidance by the player is made in an appropriate direction at an appropriate timing, the player character avoiding process by the player character control unit moves the player so that the attack by the enemy character does not collide with the player character. Therefore, the attack by the enemy character does not succeed 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 succeeded in avoiding the player character by a predetermined avoidance motion based on the player input (S502). .. In this embodiment, the predetermined avoidance operation is an avoidance operation in a predetermined direction. For example, when the player inputs the movement of the enemy character in the lateral direction and the input by pressing the input button assigned for avoidance, when the player performs the avoidance action at a proper timing, Judged as successful in avoiding the attack. When there is a movement input in a direction away from the enemy character, even if the avoidance is successful, it is not determined that the avoidance is performed by the predetermined avoidance motion. Further, if the timing of the player input is inappropriate, the attack of the enemy character cannot be appropriately avoided, and it is not determined that the avoidance is successful.

FIG. 3 shows a game screen when a predetermined avoidance operation is performed. FIG. 3A shows a state in which the enemy character 42 attacks the player character 41 by shaking his arm. In FIG. 3B, in response to the attack of the enemy character 42, the player character 41 performs a predetermined avoidance motion by inputting a sideways movement input and an avoidance input of the enemy character 42. It shows the situation. Then, FIG. 3C shows that the player character 41 succeeds in avoiding the attack of the enemy character 42 by performing a predetermined avoidance motion, and turns around the side surface of the enemy character, that is, the blind spot of the enemy character. Showing.

As shown in FIG. 3, the avoiding motion of the player character may be started before the attacking motion of the enemy character ends. In this embodiment, the enemy character control and the player character control are executed in parallel, so that the other control can be performed without waiting for the end of one control.

As a modified example, the avoidance action is not limited to the avoidance in a predetermined direction, and any avoidance action at a proper timing capable of avoiding an attack of an enemy character is a predetermined avoidance action. You can also

When it is determined that the predetermined avoidance operation is performed, the game control unit 33 commands 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 the suppression time timer. The suppression time ends when the ending condition described later is satisfied. One of the termination conditions is that a predetermined period has elapsed from the start of the suppression time. This period is determined based on the difficulty level.

The action of the enemy character is restricted during the suppression time. The action 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). The enemy character does not attack the player character during the suppression time, and neither moves nor turns so that the player character can easily attack. 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 may perform an attack or defense such as movement, attack, or turning included in a predetermined action pattern. The action pattern can be changed by replacing all the information indicating the related action with the action such as waiting. In addition, prepare an action pattern for the normal state that is not the suppression time and an action pattern for the suppression time state, and normally use the behavior pattern for the normal state. When the suppression time starts, the action pattern for the suppression time state May be used. As another embodiment, instead of or in addition to changing the action pattern, the motion of the enemy character may be delayed.

When actually fighting a mighty monster, it is dangerous for a small person to attack from the front, and it is difficult to do enough damage even if the attack is successful. It is considered effective to go under the monster's attack, sneak into a disadvantageous place such as a blind spot, and then attack. Therefore, in a game in which the player character is capable of fighting equally with the enemy character from the front, even if a high-definition image is displayed in order to realistically express that the enemy character is powerful, the player can control the enemy character's strength. You can't really feel the reality in full.

In the present embodiment, the suppression time state can be achieved by successfully performing a predetermined avoidance action against the attack by the enemy character. Since the action of the enemy character is limited during the suppression time, it is an advantageous time for the player to succeed in the attack. Here, the predetermined avoidance action is an avoidance action to the side face which is a disadvantageous place such as a blind spot for the enemy character. That is, the player character creates an advantageous state for the attack by sneaking up on the attack by the enemy character and sneaking into the blind spot, and is able to effectively attack the powerful enemy character within a predetermined time.

By understanding that it is more effective for the player to attack the enemy character after wrapping around in the blind spot of the enemy character rather than attacking the enemy character from the front, the enemy character that the player is facing is a powerful monster. Can be felt with reality. By limiting the action of the enemy character, it is possible to represent that the enemy character cannot perform sufficient attack action due to the movement of the player character to a place that is disadvantageous to the enemy character. Furthermore, in the normal state (state of non-suppression time), a larger reality can be given by increasing the damage to the enemy character due to the attack within the suppression time, as compared with the case of attacking the enemy character from the front. ..

When it is not determined that the player character has performed the predetermined avoidance process in response to the attack by the enemy character, the game control unit 33 determines whether the attack by the enemy character has succeeded (S508).

Although the player has made an input for avoidance, the enemy character is attacked if it is not determined that the predetermined avoidance has been performed due to reasons such as avoidance in a predetermined direction or improper timing. Since there is a possibility of success, it is determined whether or not the attack of the enemy character has succeeded. Even if the player does not make any input to the attack of the enemy character, the attack may be successful. Even if the attack of the enemy character is executed in the area that does not reach the player character, the attack does not succeed. If it is determined that the attack by the enemy character has not succeeded, the attack process by the enemy character ends.

On the other hand, when it is determined that the attack by the enemy character has succeeded, damage is given 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 attack power value of the enemy character and the defense power value of the player character.

Next, the degree of weakness of the player character is increased (S512). Here, the degree of weakness indicates the degree of weakness to the player's action, and the value is so high that it is estimated that the player is not good at performing actions such as attacking and evading by operating the player character, and is good at The lower the value is estimated to be. If the attack of the enemy character is successful, it is estimated that the player is not good at the action, and the degree of weakness is increased. If the attack of the player character is successful, the player is presumed to be good at the action. Reduce. For example, in the initial state, the weakness is set to 0, which is the minimum value, and the weakness is increased by 10 when the enemy character is attacked, while the weakness is decreased by 3 when the player character succeeds in the attack.

In S514, the difficulty level of the game is determined based on the difficulty level. For example, when the degree of weakness is 0 to 20, the degree of difficulty is 3 which is high, and when the degree of weakness is 21 to 40, the degree of difficulty is 2 which is medium and the degree of weakness is 41 or more At this time, 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 weakness level, and therefore is changed during the progress of the game according to the change of the weakness level. The difficulty level indicating that the player is not good at the action based on the player input is sequentially changed while the game is in progress, and the game difficulty level is changed based on this, thereby providing the game difficulty level according to the skill of the player. It becomes possible to do. When the game difficulty level is determined, the enemy character attack process ends.

Next, the player character attack processing will be described with reference to FIG. In the player character attack processing, processing is performed when an input for attacking an enemy character is made by the player via the input unit 31. First, based on the 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 has succeeded (S602). ).

When it is determined that the attack by the player character has succeeded, damage is given to the enemy character (S604). Specifically, the hit points of the enemy character are reduced by a predetermined amount. Then, the degree of weakness of the player character is reduced (S606). If the player character's attack succeeds, it is estimated that the player character is good at the action, and the weakness is reduced. Then, the difficulty level of the game is determined based on this weakness (S608).

In S610, the game control unit 33 determines based on the suppression time state information whether or not it is during the suppression time. If it is not within the suppression time, the player character attack process is terminated, 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 the present embodiment, the display unit 32 displays an action indicating that the enemy character has been damaged.

Only when the attack on the enemy character by the player character succeeds within the suppression time, by executing the enemy character reaction action, the player can be made aware that the suppression time is a special time. This makes it possible to provide the player with the enjoyment of finding the rules while playing the game, without having to provide a tutorial or the like to explain the basic rules of the game before the player starts the game.

In the present embodiment, the action pattern of the enemy character is changed during the suppression time, which is in a state advantageous to the player. The suppression time is advantageous for the player because the player realizes that the suppression time is a special time when the enemy character executes the reaction, and that the suppression effect is not taken by the enemy character. , It is possible to prompt to recognize that it is necessary to perform a predetermined avoidance in order to create the suppression time state. It is also possible to clarify the reward for performing a predetermined avoidance.

In S612, it is determined whether or not the enemy character executes a counter attack. Whether or not to execute the counter attack is determined based on a predetermined occurrence probability. Here, the probability that a counter attack will occur is determined based on the game difficulty level. For example, the probability of occurrence is 50% in the case of high difficulty, 30% in the case of medium difficulty, and 0% in the case of low difficulty. Further, it can be based on the remaining hit points of the enemy character. According to one embodiment, by multiplying the standard occurrence probability based on the remaining HP of the enemy character by a coefficient according 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) are 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 of high difficulty is 1.0, the coefficient of medium difficulty is 0.8, and the coefficient of low difficulty is 0.5. In this case, the probability of occurrence when the remaining hit points (HP) is 25%>HP≧0% is 50×1.0=50% at high difficulty and 50×0.8 at medium difficulty. =40%, and 50*0.5=25% at low difficulty. The lower the probability of a counter attack, the lower the difficulty of the game.

When it is determined that the counter attack does not occur, the player character attack process ends. When it is determined that the counter attack occurs, in S616, the enemy character attack process described with reference to FIG. 5 is started, and the player character attack process is ended. In this embodiment, as described later, the suppression time ends when a counter attack occurs.

Next, the suppression time management control will be described with reference to FIG. As described above, when the player character succeeds in avoiding an enemy character attack by performing a predetermined avoidance motion based on the input of the player, the suppression time is entered and the suppression time timer is started. The suppression time ends when at least one of expiration of the timer, occurrence of a predetermined action by the enemy character, and execution of a predetermined action by the player character based on player input is satisfied. ..

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

In the present embodiment, the game difficulty level is determined based on the difficulty level. The weakness is changed every moment based on the success of the attack by the player and the success of the attack by the enemy character, so that the technique of the player can be represented in real time. By determining the game difficulty level based on the difficulty level, and determining the suppression time and the counter probability based on the game difficulty level, it is possible to provide a game of the difficulty level corresponding to the player's technique in real time.

In the present embodiment, the predetermined action by the player character for ending the suppression time is, for example, an avoidance action. The suppression time is an advantageous time for the player to attack, and it is possible to make the player understand that the avoidance action is an inappropriate action during the suppression time when the attack of the enemy character is limited.

When 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 the information indicating the non-suppression time state, and the suppression time is ended. (S704). Here, the action pattern is changed by starting the suppression time and then returning the action pattern changed so as to limit the action of the enemy character to the normal action pattern. For example, in S504, the action pattern is changed by returning the information, which is all replaced with the action such as waiting, to the information indicating the action such as the movement, the attack, and the turn included in the predetermined action pattern.

In the process or operation described above, a process or operation can be freely performed in a certain step as long as there is no inconsistency in the process or operation such as using data that should not be used in that step. Can be changed. Further, each of the embodiments described above is an example 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.
