  Next, an online game method according to an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 3 is a flowchart showing the online game method in the embodiment of the present invention.

  First, the user connects to the online game system 100 through the user terminal 300 and executes the game (S310). Then, the online game system 100 provides the user with a plurality of game channels and a plurality of game rooms (S320), and the user enters the game channel and the game room (S330). Game channels are categorized by grade, and each user can enter a channel that matches their grade. In addition, the game channel includes a quest channel that performs a game by performing a given task, a free channel that can be entered regardless of the grade, and a survival channel that a final survivor of the game players wins. A user can enter a game room created by another user. In addition, the user can directly create a new game room and wait for the participation of another user. The user who created the game room becomes the room manager.

  The room manager can select game options such as the maximum number of games that can be entered in the generated game room, a game map, and a game type (S340). Can be selected. The room manager can select a specific game map or a random map. The layout of the terrain features can be changed according to the game map, and the position of the anti-aircraft fire that attacks the fighter can be changed. The game type includes individual battles in which individual users who participate in the game room perform individual battles, and team battles in which teams form a team such as 2: 2, 3: 3 and battle with the opponent team.

  When the manager presses the game start button to request the game start (S350), the online game system 100 transmits information necessary for the game progress including information corresponding to the selected map to each user terminal 300 (S360). ) Each user plays a game (S370).

  Each user terminal 300 plays a game while exchanging game data with each other. The game data includes position information and physical strength information of fighters of each game player. The position information may be coordinate information in a three-dimensional space. Also, the user terminal 300 can exchange predetermined game data with the game system 100.

  When the game is started, a game screen as shown in FIG. 4 is displayed on the user terminal 300. FIG. 4 is a diagram schematically showing an example of the online game screen in the embodiment of the present invention.

  As shown in FIG. 4, a fighter plane 410 operated by the user is displayed in the center of the game screen, and the fighter plane 450 operated by another user satisfies the predetermined condition. Is displayed. Hereinafter, a fighter plane displayed at the center of the game screen and steered by a user is referred to as a moving body 410, and a fighter plane steered by another user is referred to as a target body 450. The target object 450 includes enemy fighters and friendly fighters.

  The moving body 410 fires an attack item (not shown) such as a bullet or missile while flying in a three-dimensional space according to a user's movement command, and the enemy fighter of the target object 450 that appears on the game screen. Add damage to shoot down. On the moving body 410, a cross hair 415 that displays a position where the attack item is fired is displayed. The user can damage the enemy fighter by aiming the crosshair 415 at the enemy fighter and firing an attack item.

  At this time, a primary weapon (not shown) corresponding to the main weapon and a secondary weapon (not shown) corresponding to the auxiliary weapon are mounted on the left and right wings of the moving body 410, respectively.

  Primary weapons include repetitive attack items such as machine guns, twin cannons, blaster guns, and blaster guns that can be fired continuously for a period of time. The cannon is a weapon that has a short range, but can be fired at high speed, and the bullets that are fired are concentrated at one position to form an impact point. The twin-engine cannon is equipped with two cannons. Two shots are fired at the same time. Blaster guns and blaster guns are weapons in which bullets are spread (spread) within a certain range to form impact points, and the blaster gun is spread over a wider range than blaster guns.

  Secondary weapons include single-shot attack items such as railguns, ultrarailguns, plasma guns, guided missiles, and high-speed missiles that can be relaunched after a certain period of time has elapsed since launch. Railguns are characterized by long range and high destructive power instead of a narrow hit range, and ultrarail guns take longer to reload instead of having more destructive power than railguns. In addition, the guided missile explodes by tracking an enemy fighter that is aimed at the crosshair 415 and is in a lock-on state. A plasma gun launches small energy bullets and has high destructive power, but the firing speed of energy bullets is slow, and many energy bullets can be collected and fired at once, but in this case, a locked-on enemy like a guided missile Follow a military fighter and explode. High-speed missiles are similar to plasma guns, but have a fast launch rate.

  Each primary and secondary weapon has a unique range, the range of secondary weapons is 3,500-6,000, compared to the range of primary weapons 1,000-2,000 Long. For example, the gun is 1,200, the plasma gun is 4,000, and the rail gun is 5,000.

  Crosshair 415 includes aiming point 415a, primary weapon gauge 415b, and secondary weapon gauge 415c. The aiming point 415a is located at the center of the cross hair 415 and indicates a position where the primary weapon and the secondary weapon are fired. The primary weapon gauge 415b and the secondary weapon gauge 415c have a symmetrical circular shape with respect to the aiming point 415a, and information on the availability of primary and secondary weapons, information on the remaining bullets, etc. The usage information regarding the primary weapon and the secondary weapon is shown.

  A radar display window 420 is displayed on the lower left side of the game screen. The radar display window 420 is displayed in a circle around the moving body 410, and the angle of the dotted line inside the radar display window 420 corresponds to the viewing angle that currently appears on the game screen. In the radar display window 420, the moving body 410 and the target object 450 are displayed in a predetermined form. The target object 450 positioned in the three-dimensional space is projected on the horizontal plane on which the moving body 410 is positioned, and is displayed on the radar display window 420 when the projected target object 450 is within a predetermined distance from the moving body 410. .

  In the center of the radar display window 420, the moving object 410 is displayed as a triangle, and the target object 450 positioned around the moving object 410 is displayed as a diamond. At this time, the direction of the upper vertex of the triangle is the same as the direction indicated by the cross hair 415 of the moving body 410. The radar display window 420 displays not only the target object 450 that appears on the game screen, that is, the target object 450 that is within the viewing angle, but also the target object that does not appear on the game screen. The positional relationship can be easily grasped.

  The radar display window 420 can be displayed at an arbitrary position such as the upper left side, the upper right side, or the lower right side of the game screen, and the forms of the moving body 410 and the target object 450 displayed in the radar display window 420 are also a triangle and a rhombus, respectively. It can be configured in a different form.

  Although not shown in FIG. 4, the game screen can be configured to display fixed terrain features such as sky, ground, enemy base, mountain, river, and building. It can also be configured to display the weapons that are mounted, weapons that can be mounted, items, and the like, and can be configured to display an instrument panel that indicates the physical strength, flight speed, etc. of the moving body 410.

  On the other hand, a predetermined mark for the object 450 within the viewing angle, for example, a hidden mark, a far mark, an attackable mark, a lock-on mark, etc. A method for displaying such a mark will be described in detail with reference to FIGS. 5 and 6 together with FIG.

  FIG. 5 is a flowchart illustrating a method for displaying a predetermined mark on an object in a game screen according to an embodiment of the present invention. FIG. 6 is a game in which a predetermined mark is displayed on an object according to an embodiment of the present invention. It is an illustration figure showing a screen roughly.

  Referring to FIG. 5, the user terminal 300 receives position information of the target object 450 that is moved by another user's operation from the other user terminal (S510). Of course, the user terminal 300 also transmits the position information of the moving body 410 to another user terminal so that a predetermined mark can be displayed on the other user terminal. The user terminal 300 calculates the direction of the target object 450 based on the position information of the moving object 410 and the position information of the target object 450, and determines the distance between the moving object 410 and the target object 450. Calculate (S515).

  With reference to the calculated direction of the object 450, it is determined whether the object 450 is within the viewing angle of the moving object 410 (for example, whether the position information of the object 450 is included in a predetermined angle range (coordinates)). (S520) If the object 450 is not within the viewing angle, the target object 450 is returned without displaying a predetermined mark. If the object 450 is within the viewing angle, the object 450 is shielded by the special terrain feature. Is determined (S525).

  As a result of the determination in step S525, when the target object 450 is shielded by the special terrain feature, the target object 450 is returned to the operation without displaying a predetermined mark. It is determined whether there is a general terrain feature between 410 and the object 450 (S530).

  Examples of the special terrain feature include fog and clouds, and the target object 450 shielded by the special terrain feature is not captured by the radar, and therefore is not displayed on the radar display window 420. On the other hand, the target object 450 shielded by the general terrain feature is captured by the radar and cannot be attacked, but is displayed with a predetermined mark. Examples of general terrain features include a mountain, a reef, a building, a rock wall, and a water surface.

  If the result of determination in step S530 is that there is a general terrain feature between the moving object 410 and the target object 450, a hidden mark is displayed on the general terrain feature shielding the target object 450 (S535). The hidden mark can be displayed by, for example, a symbol 、 and is displayed as small as possible on the general terrain feature shielding the object. Referring to FIG. 6, three objects shielded by the reef 470 are displayed as hidden marks 461 on the upper left side of the game screen. By displaying the hidden mark on the target object 450 shielded by the general topographic feature in this way, not only can the position of the target object 450 be easily grasped, but the target object 450 is in a state where it cannot attack. Can be displayed.

  As a result of the determination in step S530, there is no general terrain feature between the moving body 410 and the target object 450 (for example, based on the coordinates of the moving body 410, the target object 450, and the general terrain feature, the coordinates of the moving body 410). When the general terrain feature is not located on the straight line connecting the coordinates of the object 450 and the object 450), the object 450 is attached to the moving object 410 with reference to the distance between the object 450 and the moving object 410. It is determined whether it is within the range of the next weapon (S540), and if it is not within the range, a long distance mark is displayed on the object 450 (S545). The long distance mark can be displayed by, for example, a symbol ◇ and is displayed so as to surround the target object 450. Referring to FIG. 6, a long distance mark 463 is displayed on the object 453 displayed on the upper right side of the game screen. Thus, by displaying the long distance mark for the target object 450 that is outside the range of the secondary weapon, it is possible to display that the target object 450 cannot be aimed with the secondary weapon.

  If it is determined in step S540 that the target object 450 is within range, it is determined whether the secondary weapon is a navigable weapon and the target object 450 is aimed at the aiming point 415a (S550). When the secondary weapon is a navigable weapon and the target object 450 is aimed at the aiming point 415a, a lock-on mark is displayed on the target object 450 (S560), and the secondary weapon is a navigable weapon. When the target object 450 is not aimed at the aiming point 415a, an attack possible mark is displayed on the target object 450 (S555), and then the operation is returned.

  For example, as shown in FIG. 6, the attack possible mark 465 surrounds the target body 455 in a form similar to an inverted triangle, and the range of the secondary weapon currently mounted on the moving body 410 is the target body 455. It shows that it is within a distance and is in an attackable state by aiming with the cross hair 415.

  The hidden mark, the long distance mark, and the attackable mark are displayed with different hues depending on the type of the target object 450. For example, when the target object 450 is an enemy fighter, the color of the mark is dark blue or allied If it is a fighter, it can be configured in green.

  On the other hand, when the target object 450 that is a weapon that can be guided by the secondary weapon and the attackable mark is displayed is aimed at the aiming point 415a, the attackable mark displayed on the target object 450 is the lock-on mark. Changes to. When changing to the lock-on mark, a simple image effect can be displayed around the object 450 so that the user can easily know that the lock-on state has been entered. For example, as shown in FIG. 6, the lock-on mark 467 has the same form as the attackable mark 465, but the hue can be made darker or different, and the hue of the attackable mark 465 is amber. In this case, the lock-on mark 467 can be red.

  The lock-on mark is displayed for a lock-on duration (for example, 2 seconds), and an attackable mark is displayed again after this time has elapsed. This is because the object 450 is within the range of the secondary weapon. Only in certain cases. The lock-on mark is displayed only when the target object 450 is an enemy fighter.

  Even if the target object 450 on which the lock-on mark is displayed deviates from the cross hair 415, when the user fires the secondary weapon, the secondary weapon tracks and explodes the target object 450. By displaying the lock-on mark in this way, it can be displayed that the target object 450 is in a state where it can be damaged by the secondary guided weapon.

  On the other hand, as shown in FIG. 6, the physical strength and distance information 469 of the target objects 455 and 457 can be displayed under the attack possible mark 465 and the lock-on mark 467, respectively, and any one of them can be displayed as necessary. Can also be displayed.

  When the object 450 uses the item “stealth”, the object 450 is not locked on. The target object 450 using the stealth item is not captured by the radar and can be confirmed with the naked eye on the game screen, but a hidden mark, a long distance mark, and an attack possible mark are displayed on the target object 450. . However, a predetermined symbol x can be displayed inside the attackable mark to indicate that lock-on cannot be performed, and an image effect that a wavelength flows around the target object 450 can be displayed to indicate that a stealth item has been used. it can.

  In addition, you can display the prescribed characters, symbols, images, etc. for the enemy fighter who shot down your own fighter most recently during the battle, indicating that the fighter is a rival. It is possible to attack more aggressively.

  In this way, by displaying a predetermined mark or the like on the terrain feature shielding the target object 450 and the target object 450 by the position of the secondary weapon and the target object 450 mounted on the moving object 410, the user can The positional relationship between the moving body 410 and the target object 450 can be more easily grasped, and as a result, the user can be more immersed and play a game.

  Next, a method for displaying the aiming point 415a of the crosshair 415 shown in FIG. 4 in relation to the primary weapon differently will be described in detail with reference to FIGS. 7 and 8 together with FIG.

  FIG. 7 is a flowchart illustrating a method for displaying a crosshair aiming point associated with a primary weapon according to an embodiment of the present invention, and FIG. 8 illustrates a crosshair associated with a primary weapon according to an embodiment of the present invention. It is an illustration figure showing a game screen roughly.

  Referring to FIG. 7, the user terminal 300 receives the position information of the target object 450 that is moved by another user's operation from the other user terminal (S610). The user terminal 300 calculates the direction of the target object 450 based on the position information of the moving object 410 and the position information of the target object 450, and calculates the distance between the moving object 410 and the target object 450. (S620).

  With reference to the calculated direction of the target object 450, it is determined whether the target object 450 is within a predetermined viewing angle of the moving body 410 (S630). If the target object 450 is within the range of the primary weapon currently mounted on the moving body 410, it is determined (S640).

  If the result of determination in step S640 is not within the range of the primary weapon, the operation is returned, and if it is within the range of the primary weapon, the movement path of the object 450 is calculated (S650). The movement path is calculated based on at least one previous position information of the object 450 (position information that was located before moving to the current position) and the current position information. The moving position can be predicted.

  Thereafter, it is determined whether the primary weapon is fired and the object 450 can be hit (S660).

  The bullet of the fired primary weapon proceeds along the line of sight, and the required time varies depending on the impact distance. Therefore, considering the bullet velocity and the moving path of the object 450, the fired primary weapon bullet and the moving object 450 meet after a predetermined time (for example, the mutual coordinates after the predetermined time elapses). Is hit, it is determined that a hit is possible. When the hit is not possible, the operation is returned, and when the hit is possible, the aiming point 415a of the cross hair 415 is enlarged and displayed (S670).

  Referring to the game screen of FIG. 8, the aiming point 415d when the hit is possible is enlarged and displayed as compared with the aiming point 415a shown in FIG. The object 459 that is visible on the game screen is not aimed at the aiming point 415d of the crosshair 415, but if the primary weapon is fired at this time, the primary weapon bullet hits the object 459 and causes damage. be able to. The hue of the aiming point 415d can be displayed so as to be different from the hue of the aiming point 415a, and the form of the aiming point 415d can be displayed differently from the form of the aiming point 415a. It is also possible to display at least one of them differently.

  Since the moving body 410 and the target object 450 arbitrarily move in a three-dimensional space, it is difficult to accurately aim the target object 450 and fire the primary weapon. However, by predicting the movement path of the target object 450 in this way and determining the possibility of hitting, and displaying the aiming point 415d differently from the aiming point 415a according to the determination result, the primary weapon is currently displayed to the user. Can be used to make it easier for the user to use the primary weapon.

  Referring to FIG. 3 again, the user shoots down the enemy fighter while viewing the predetermined mark displayed on the object 450 and the crosshair 415 associated with the primary weapon. Play the game while maneuvering to defend the fighters. When a game is determined while the user is playing the game (S380), the game is ended (S390). The game will be won by the game player (or team) who shot down more enemy fighters within a given time, or the game player (or team) who shot down a given number of fighters first will win. At this time, even if the fighter is shot down, it can rejoin the battle. Alternatively, the final survivor or the team with the remaining survivors can be configured to win, in which case the fighter cannot be rejoined once shot down. It can also be configured so that the game player (or team) who wins a high score by converting the damage to the opponent's fighter without deciding the game according to the number of shots down will win. In this case, the fighter will not be shot down even if damaged. It is also possible to determine the game by a method such as a 3rd game 2 first win system which is not a first game. In this way, various game determination methods can be selected by the room manager as a game option.

  When the game is over, the online game system 100 determines the ranking of each user / team based on the number of fighters shot down by each user / team or the points earned by each user / team. A player / team is given experience points and game money according to ranking. Then, after updating information such as the battle record, experience value, and game money of each user, the information is stored in the database 130.

  According to the embodiment of the present invention, the method of displaying a predetermined mark on a target body or the like or displaying the cross hair associated with the primary weapon can be applied not only to an online shooting game but also to an independent shooting game device. In this case, the enemy fighter is not operated by another user, but is operated by the game device, and the game device displays a predetermined mark and cross hair based on the status information of the enemy fighter.

  Also, the method of displaying a predetermined mark on an enemy fighter plane or fixed terrain or displaying a cross hair associated with a primary weapon is not only a flight shooting game but also a first person shooting game in which a human or a robot appears. (First person shooting, FPS), a real time strategy simulation game (real time strategy, RTS), a role playing game (roll playing game, RPG), an action game, and the like. Of course, these can be displayed not only in a three-dimensional space but also in a game executed in a two-dimensional space.
