Description

  The present invention relates to an electronic device that displays on a game screen a first object operated by a player and a second object that fires a flying object.

  Currently, there are various video games that display on the game screen the own machine object operated by the player and the enemy object that fires shots (enemy bullets, beams, lasers, etc.) against the own machine object. Existing. In this type of shooting game, shots (attacks) fired from enemy objects (airplanes, characters (invaders), animals, people, etc.) existing in the game space are avoided by moving their own objects by player operations and avoiding them. There are many things that attack an object and destroy it.

  Usually, points are added by destroying enemy objects, and it is possible to compete for superiority or inferiority according to the finally acquired score. Also, when the number of times that a shot from an enemy object has made contact with the object (miss) reaches the specified number, the game ends.

Conventionally, there has been considered a game in which a player can obtain a higher score than other players when competing for a score (for example, Patent Document 1). In the game described in Patent Document 1, the score increases depending on how much the bullets fired by the enemy are avoided. It is.
JP 2005-095447 A

  In this way, in conventional shooting games, not only can you score by attacking enemy objects, but you can also earn high scores by defeating enemies while avoiding more bullets from enemy objects This makes it possible to enjoy the game development more.

  However, in the game described in Patent Document 1, the attack from the enemy object is not different from the conventional shooting game in that the own object is operated so as not to come into contact with the shot (attack) fired from the enemy object. There was a need to provide another technique to avoid this so that the player can enjoy the game more.

  Also, in conventional shooting games, if the enemy bullet fired from the enemy object is high-speed, if there is an own object near the enemy object, the enemy bullet is fired and touched before the enemy bullet was seen. It will be detected as a mistake and will be a mistake. In this case, it is difficult for the player to understand why the mistake is made, and there is a possibility that the player may have an absurd impression on the game.

  The present invention has been made in consideration of the above-described circumstances, and an object of the present invention is to provide another method for avoiding an attack fired from an enemy object, and to further improve the game performance, and a game program Is to provide.

The present invention provides an electronic device that displays on a game screen a first object that is controlled in accordance with a player's operation and a second object that causes the flying object to be emitted. Display control means for calculating a position in the game screen and controlling display; contact determining means for determining whether the flying object controlled by the position control means is in contact with the first object; and the second A first time when the flying object is determined to be in contact with the first object by the contact determination means when a time since the flying object is fired from an object is within a predetermined time set in advance; 1 and after the predetermined time has elapsed, the contact determination State determining means for determining any of the second states in which it is determined that the flying object is in contact with the first object by a step, and the first object in the case of being determined to be the first state And a processing means for executing a display process for destroying the first object on the game screen when it is determined to be the second state.

  According to the present invention, it is possible to provide another method for avoiding an attack fired from an enemy object, and to further improve the game performance.

FIG. 2 is a diagram illustrating an external configuration of the mobile phone 1 according to the present embodiment.
A cellular phone 1 shown in FIG. 2 is configured to be a foldable type, and a main unit 30 and a display unit 31 are connected by a hinge mechanism. The hinge mechanism is rotatable from a closed state in which the display unit 31 is superimposed on the main unit 30 to an open state in which the display unit 31 is separated. FIG. 2 shows an open state in which the display unit 31 is opened by a hinge mechanism (not overlapped with the main unit 30) when a game is executed.

  The main unit 30 stores main components. As shown in FIG. 2, the unit unit 30 has a determination key 32, a cross key 33, numeric keys, a call key, a disconnect key, and the like on the surface of the unit.

  When the game is executed, the determination key 32 is used to instruct a shot (attack) from the own machine object 41. The cross key 33 is used to instruct the moving direction of the own object 41 in the game screen. The “*” key is assigned a function as a sound switching key 34, the “0” key is assigned as an auto-shot switching key 35, and the “#” key is assigned as a vibration switching key 36. The sound switching key 34, the auto shot switching key 35, and the vibration switching key 36 are used to instruct on / off of each function. The function key 37 is used for selecting a soft key displayed on the display. The soft keys are displayed according to the game situation under the control of the control unit 10 (game execution unit 10d). For example, when the function key 37 is operated (pressed) while a menu display soft key is displayed, the game execution unit 10d displays a menu on the display.

Next, the operation of the game executed on the mobile phone 1 in this embodiment will be described.
3, 4, and 5 are diagrams illustrating an example of a game screen at the time of game execution in the present embodiment. The game executed by the mobile phone 1 (game program 17a) of the present embodiment is provided with a plurality of game stages so that the difficulty increases sequentially according to the score obtained by the player by the game play. Move to different stages.

  In the game screen of the stage shown in FIG. 3, a plurality of enemy objects 40 (second objects) are arranged, and are controlled to move downward while moving in the left-right direction, for example. The enemy object 40 randomly fires an attack shot (flying object) in a downward direction where the own object 41 (first object) is arranged. Note that the flying objects representing attack shots include various forms such as beams, enemy bullets, lasers, and missiles in the game space.

  In the stage shown in FIG. 3, the own object 41 is controlled to move in the left-right direction in response to the player's operation on the left / right key of the cross key 33 at the bottom of the game screen. In addition, when the auto-shot 41 is turned on by the auto-shot switching key 35 or when the shot is instructed by the decision key 32, the own object 41 is shot in the direction of the enemy object 40 (upward). Fire (flying object). When the auto shot is on, shots are continuously fired from the own object 41 without any player operation (attack continuously). When the enter key 32 is pressed, a shot is fired from the own machine object 41 each time. When this shot hits (hits) the enemy object 40, a score is added. The player increases the score by making an attack on the enemy object 40 while moving the position of the own object 41 so as to avoid an attack from the enemy object 40.

FIG. 4 shows an example of a stage up from the stage shown in FIG. In the stage shown in FIG. 4, the type of the enemy object 40 changes, and the amount of attacks from the enemy object 40 increases. In addition, the type of the own object 41 is changed, and the attack power (number of shots that can be shot) is increased.

  FIG. 5 shows an example of a further stage up from the stage shown in FIG. In the stage shown in FIG. 5, the enemy objects 40 are randomly arranged, and the enemy objects 40 having greatly different shapes are also included. In the stage shown in FIG. 5, the own object 41 is controlled not only to move in the left-right direction but also to move in the up-down direction in response to the operation of the up / down key of the cross key 33.

  In the game screen, the score acquired by the player, the remaining number of the player's own machine (the number of times an attack from the enemy object 40 is allowed until the game is over), the number of chains (continuously) The number of times the enemy object 40 has been shot down (hit)) is displayed.

Next, shot determination processing in the game of the present embodiment will be described with reference to the flowchart shown in FIG.
Here, it is assumed that the game is being executed at the stage shown in FIG. That is, the own object 41 can be moved in any direction of the up, down, left, and right directions in the game screen by operating the cross key 33. Therefore, the own object 41 can be brought close to or separated from the plurality of enemy objects 40 displayed on the game screen.

  The game execution unit 10d fires a shot from the enemy object 40 at an arbitrary timing. When the game execution unit 10d fires a shot from the enemy object 40 (step A1, Yes), the game execution unit 10d calculates the position of the shot after being fired from the enemy object 40, and the shot (flying object) at that position. Is displayed.

  When the game execution unit 10d displays a shot fired from the enemy object 40, the game execution unit 10d displays, for example, semi-transparent within a predetermined time to be described later, and cancels the semi-transparency after the predetermined time (described later) has elapsed. To indicate that it is materialized. That is, in a semi-transparent shot, it is expressed on the display that the own object 41 is not destroyed even if it is touched (hit).

  For example, when the game execution unit 10d displays a game screen on a display, the game execution unit 10d calculates the position of each object (including a shot) every frame (for example, 1 frame 1/15 second), and displays the object according to the position. The control to change the position is executed.

  The game execution unit 10d determines whether the shot is in contact with the own machine object 41, that is, whether the attack is hit (hit). Here, when it is determined that the game has not been touched (no hit) (step A4, No), the game execution unit 10d has not passed the preset specified time (step A6, No). Similarly, it is determined whether the shot is in contact with the enemy object 40 while updating the position of the shot for each frame. As the specified time, for example, 4 frames are set in advance.

  If it is determined that a shot from the enemy object 40 has touched the own object 41 within the specified time, the game execution unit 10d generates a “Nagoya Shoot” as a special situation, that is, “Nagoya Shoot” is established. The number of times is displayed on the game screen (step A4), and a bonus is added to the score (for example, 758 points) (step A5).

  FIG. 7 is an example of a game screen showing a situation where “Nagoya Shooting” is established. As shown in FIG. 7, the shot 42 fired from the enemy object 40 has moved a predetermined distance before the specified time 43 (four frames) has elapsed. Here, the player operates the cross key 33 to move the own object 41 to a position where the shot 42 fired from the enemy object 40 passes within a specified time, thereby establishing “Nagoya Shoot”. Can be made. FIG. 8 shows an example in which the “Nagoya Shooting” occurrence count 44 is displayed on the game screen.

  On the other hand, when the shot does not contact the own object 41 within the specified time (step A6, Yes), the game execution unit 10d continues to update the shot position for each frame (step A7), Is in contact with the own machine object 41 (step A8). The game execution unit 10d determines whether or not the own machine object 41 has been hit until the shot 42 reaches the limit range and disappears (step A11).

  When it is determined that the game execution unit 10d has come into contact with the own machine object 41 before the shot disappears (step A8, Yes), the game execution unit 10d displays a screen indicating that the own machine object 41 has been destroyed by the attack. At the same time (step A9), a process of reducing the remaining number is executed (step A10).

  In this way, the game execution unit 10d determines that the shot 42 fired from the enemy object 40 has contacted (hit) the own object object 41 within the specified time (first state) and the own object after the specified time has elapsed. It is determined which state is in contact with 41 (second state) (steps A3 and A8), and the processing is switched according to the determination result. That is, in the first state, a bonus addition process is executed, and in the second state, a process of reducing the remaining number is executed assuming that the enemy object 40 has been attacked.

  Therefore, the player not only attempts to add a score by making an attack on the enemy object 40 while avoiding an attack from the enemy object 40, but also approaches the enemy object 40 that is about to fire a shot, Bonus addition can be obtained by making a contact (hit) within a specified time after the is launched.

  In the game according to the present embodiment, the thrill of taking a risky action and a sense of accomplishment can be given to the player, and the stress factor for the player can be recognized as a pleasure factor at the same time, so that higher game performance can be provided. .

Also, even if the shot fired from the enemy object 40 is contacted (hit) until the specified time elapses, the own object 41 is not destroyed. When positioned, it is avoided that the shot is destroyed without visually recognizing the shot. That is, by giving another method for avoiding an attack fired from an unprecedented enemy object 40, a mistake that the player recognizes as absurd will not occur, so that the game does not have a bad impression Can be.

  In the above description, when the shot 42 fired from the enemy object 40 is displayed, if it is within the specified time since the shot, it is displayed in a semi-transparent state, and after the specified time result is displayed in a materialized form. Of course, it is possible to use other machine display forms as long as the display form is different within the specified time and after the lapse of the specified time.

  Further, in the above description, the speed of the shot fired from the enemy object 40 is not described in detail. For example, the shot speed may be different depending on the type of the enemy object 40 (the same type of enemy object 40 may fire multiple shots at different speeds). In this case, as a result of calculating the shot position for each frame, if the shot is fast, the distance moved within the specified time is long, and if the shot is slow, the distance moved within the specified time. Is shorter than that. That is, simply moving the own object 41 close to the enemy object 40 to a predetermined distance does not necessarily result in “Nagoya shooting”, so the enemy object 40 and the timing at which the shot is fired should be checked to determine the own object 41. It is necessary to move to the correct position. Therefore, in order to obtain a high score, a more complicated response is required, so that the game performance is improved.

  In the above description, a game in which the player's own object 41 controlled by the player fights the enemy object 40 controlled by the computer is described as an example. Alternatively, the present invention can be applied to a game in which a plurality of objects individually controlled by two or more players play against each other. In other words, it is determined whether or not a shot in which a plurality of objects are fired with each other until a specified time (for example, 4 frames) has passed since the shot is fired. (Destruction).

  In the above description, the shots fired from the enemy object 40 are described as targets. However, the flight objects fired from various objects displayed on the game screen other than the enemy object 40 are targeted. be able to. For example, an object not related to an enemy ally or a flying object fired from an ally object may be targeted.

  In the above description, when the own object 41 touches (hits) the shot 42 fired from the enemy object 40 within the specified time, a bonus addition process is executed. Is executing a display process for destroying the own object 41, but other processes may be executed.

  Further, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.

  In addition, the method described in the embodiment uses, as a program (software means) that can be executed by a computer, for example, a magnetic disk (flexible disk, hard disk, etc.), an optical disk (CD-ROM, DVD, MO, etc.), and a semiconductor memory. It can also be stored in a recording medium such as (ROM, RAM, flash memory, etc.), or transmitted and distributed via a communication medium. The program stored on the medium side also includes a setting program that configures in the computer software means (including not only the execution program but also a table and data structure) that is executed by the computer. A computer that implements the present apparatus reads the program recorded on the recording medium, constructs software means by a setting program in some cases, and executes the above-described processing by controlling the operation by the software means. The recording medium referred to in this specification is not limited to distribution, but includes a storage medium such as a magnetic disk or a semiconductor memory provided in a computer or a device connected via a network.
