Description

  The present invention relates to an image display method capable of avoiding cruel depiction such as bouncing a person while making a person appear in a virtual space such as an urban area, a storage medium storing a program for executing the image display method, and the image The present invention relates to an electronic device that executes a display method.

  Conventionally, there are roughly two types of racing game devices provided in amusement facilities and the like. One is to set a single road from point A to point B, and the player competes for time to start from point A and reach point B. In the other, a circuit course is set, and the player laps a predetermined number of times to compete for the required time. Some of these racing game devices are provided with a driving simulation device such as a motorbike or an automobile. Since the player can play the game as if he / she boarded the driving simulation device and actually got on a motorbike, a car or the like, it is rich in realism and very popular.

  Although conventional race game devices are devised for course setting and driving simulation devices, the basics of the race game are not changed, and therefore, the appearance of a novel race game is strongly demanded. In response to such a request, unlike the conventional one where the course is set, a new urban area that reproduces the urban area of a large city as a virtual space and can travel freely outside the road within the urban area Race game devices have been proposed.

  If it is possible to travel freely in an urban area, a situation where a person in a virtual space collides with the person is assumed. In recent years, avoiding cruel depiction as a game image has been strongly screamed, and images that jump humans must be avoided. In order to avoid such a situation, it is conceivable that humans do not appear in the virtual space, but it is unnatural that there are no people in the urban area, and there is a tendency to lack realism. In addition, it is possible to express an image that slips rather than jumps even if it collides with a human being, but an unnatural feeling cannot be denied.

  In addition, if it is possible to travel freely in an urban area, the player may get lost, and it is necessary to give the player a direction to the destination. In such a case, a direction instruction that is easy for the player to understand is required.

  Furthermore, various devices have been conventionally devised as running simulation devices for racing game devices. However, devices that are closer to the feeling of getting on an actual vehicle are always required, and further improvements are required.

Ys = (Y / Z) × h
When displaying a game, a motorcycle, a city area such as a building, an arrow, and the like are displayed in a three-dimensional virtual space while changing the viewpoint. When the object moves like a motorcycle, the position of the viewpoint O fixed to the object also moves, and as the viewpoint O moves, the projected image of another object also changes.

(Racing game display method)
A race game display method according to the present embodiment will be described with reference to FIGS.

  In the racing game of the present embodiment, as shown in FIG. 6, the city of Los Angeles is reproduced as a virtual space. From the Los Angeles airport, set up a vast urban area including Santa Monica, Beverly Hills, Hollywood, and Downtown as a racing game area. A player can freely travel anywhere in this vast area by his motorbike. It is characterized in that it can travel freely in areas other than roads.

  In the racing game according to the present embodiment, a destination is set, and the user quickly competes to reach the destination. Players tend to lose track of their position and direction because they can run freely in the virtual space. For this reason, the direction instruction to the destination is appropriately performed.

  In this embodiment, a large number of points for giving direction instructions to the urban area of the virtual space are set in advance. When the motorbike enters the proximity area that is a fixed distance away from the direction indication point, an arrow toward the destination is displayed. For example, road intersections indicated by P1 to P8 in FIG. 6 are set as direction indication points. Note that important points other than intersections, in front of famous shops, bus stops, etc. may be set as direction indication points.

  Specific examples of the traveling direction display method according to the present embodiment are shown in FIGS. When the motorcycle operated by the player approaches within a predetermined distance from the direction indication points P1 to P8, the shortest direction to the destination is displayed on the direction indication points P1 to P8. If the destination is on the left side as viewed from the direction indication point, it is displayed as shown in FIG. 7 (a). If the destination is on the right side as viewed from the direction indication point, it is displayed as shown in FIG. 7 (b). If the destination is on the other side when viewed from the direction indication point, it is displayed as shown in FIG. 8 (a). If the destination is on the near side as viewed from the direction indication point, it is displayed as shown in FIG. 8 (b). To do.

  The arrows shown in FIGS. 7A to 8B are perspective views of the same object arranged in the three-dimensional virtual space from different viewpoints. A two-dimensional projection image is determined by seeing through an arrow, which is a three-dimensional object, from a predetermined viewpoint as shown in FIG.

  As an arrow display method, the three arrows shown in FIGS. 7 to 8 may be displayed as they are, the three arrows may be displayed in order along the indicated direction, or the entire arrow blinks. You may make it do. In short, any display method may be used as long as it is easy for the player to grasp the indicated direction.

  Further, when there are two directions at the direction indication point that are the shortest to the destination, arrows in both directions are combined and displayed. For example, if the destination is on the left side and the other side when viewed from the direction indication point, the arrow in FIG. 7A and the arrow in FIG. 8A are combined and displayed.

  A feature of the traveling direction display method according to the present embodiment is that the same direction instruction is given regardless of the position of the motorcycle operated by the player. That is, the indicated direction is determined without depending on the positional relationship between the direction indication point and the motorcycle. In a conventional car navigation system or the like, a direction instruction is calculated each time according to the position of a traveling vehicle to determine an instruction direction. In this embodiment, if a destination is determined, a direction instruction point in a virtual space is determined. The indication directions displayed in are the same. This is very effective when a plurality of players participate in a communication battle. When a plurality of players participate, it takes a calculation time to calculate the instruction direction for each motorcycle of each player, but in this embodiment, the instruction direction to be displayed without being recalculated for each player. This is because it can be determined.

  In determining whether or not the motorcycle has approached the direction indication point, a region of a circle or a sphere having a predetermined radius centered on the motorcycle may be simply set as the proximity region, and the traveling direction and speed of the motorcycle are taken into consideration. Then, it may be determined so as to cover an area where the vehicle is scheduled to travel in the future.

(Person collision avoidance method)
In the race game according to the present embodiment, the vehicle can run freely in the urban area of the virtual space regardless of the road, and there is a risk of colliding with a person in the urban area. Depending on the player, it is possible to intentionally operate the robot so as to collide with a human. In the present embodiment, in order to avoid such a situation, when the motorcycle approaches the person, a situation in which the person is forced to move away to collide is avoided.

  For example, when a motorcycle approaches a person who is far away, the movement of the person in the running direction stops as shown in FIG. Further, when approaching further, as shown in FIG. 9B, the person is forced to move in the horizontal direction. Even if a player chases a person with a motorcycle, the person is forced to keep moving so that the person is not beaten.

  Details of the human collision avoidance method according to the present embodiment will be described with reference to FIGS.

  First, an algorithm of a person collision avoidance method will be described with reference to FIG. In the present embodiment, for the traveling motorcycle B, there are a dangerous area where the motorcycle may collide, a caution area that needs to collide with the motorcycle, and a safe area that does not need to consider the collision with the motorcycle. Determine. A dangerous area and a caution area are determined for the center position O1 of the motorcycle B in consideration of the speed vector VB of the motorcycle B. A sphere having a radius proportional to the speed | VB | and centered on the position O2 shifted by a distance proportional to the speed | VB | in the speed vector VB direction from the center position O1 of the motorcycle B is dangerous. It becomes an area. Similarly, a sphere having a radius proportional to the speed | VB | is centered on a position O3 shifted from the center position O1 of the motorcycle B in the speed vector VB direction by a distance proportional to the speed | VB |. Become.

  The person in the danger area is forced to move away from the motorcycle B. The persons H1 and H2 behind the motorcycle B as viewed from the traveling direction of the motorcycle B are forced to move away from the current position B1 of the motorcycle B as shown in FIG. As shown in FIG. 10, the persons H3, H4, and H5 in front of the traveling direction of the motorcycle B are about to go around the motorcycle B, for example, the center position O1 of the motorcycle B and the persons H3 and H4. , H5 is forcibly moved in a direction perpendicular to the straight line connecting H5. The persons H3 and H4 on the left front side of the motorcycle B move to the left side, and the person H5 on the right front side moves to the right side.

  It should be noted that the person in the danger area escapes completely from the area requiring caution until it reaches the safety area.

  The person in the attention area temporarily stops the movement even when walking, so that the subsequent movement to avoid danger is smooth. For example, as shown in FIG. 10, the persons H6 and H7 in the area requiring attention temporarily stop and perform an operation of looking at the motorcycle B.

  A person in the safety area outside the area requiring attention moves according to a predetermined program. For example, as shown in FIG. 10, persons H8, H9, H10, and H11 in the safety area perform an operation of walking and running according to a predetermined program regardless of the movement of the motorcycle B.

  Next, the procedure of the person collision avoidance method will be described with reference to the flowchart of FIG.

  First, a dangerous area where a motorcycle will pass in the future and a caution area where a motorcycle may pass are determined from the position, traveling direction, and speed of the motorcycle (step S10).

  Next, it is determined in which area the passerby is located (step S11).

  If the passerby is in a safe area that is neither a dangerous area nor a caution area, he or she walks normally without giving any change to the passerby (step S12).

  When the passerby is in the area requiring attention, the passerby stops and looks at the situation (step S13). This is to ensure smooth movement when the motorcycle is approaching and escaping, and also to prevent passersby from inadvertently moving into the danger area.

  If the passerby is in the danger area, it is determined whether the passerby is in front of or behind the motorcycle (step S14).

  If the passerby is in front of the motorcycle, it escapes in a direction to go around the motorcycle while keeping away from the course of the motorcycle (step S15). With respect to a line connecting the position of the motorcycle and the position of the passerby, for example, escapes in a direction of about 90 degrees. In addition, you may make it let a passerby escape in the direction of a predetermined angle with respect to the advancing direction of a motorcycle.

  If the passerby is behind the motorcycle, he escapes away from the current motorcycle position (step S16).

  As described above, according to the present embodiment, it is possible to avoid cruel depiction such as bouncing a person while making a person appear in the city area, and to give an easy-to-understand direction instruction to an operator who travels freely in the city area. it can.

[Second Embodiment]
A game device according to a second embodiment of the present invention will be described with reference to the drawings.

  The taxi game by the game device according to the present embodiment is a game in which a player travels to a destination with a passenger as a taxi driver. Compete to carry many passengers to their destinations and earn a lot of boarding fees within the play time.

  The basic configuration is the same as that of the first embodiment, except that a running simulation device (not shown) operated by the player simulates a taxi instead of a motorcycle.

  In the game according to the present embodiment, a taxi operated by a player finds a passenger, gets the passenger on board, then takes the passenger to a destination indicated by the passenger, and receives a taxi fee corresponding to the distance. Players compete for how quickly they find passengers, get on board, get passengers to their destinations quickly, and earn a lot of boarding fees. Basically, it is a game for competing for the player's running technique, but there is also a game with an element of luck depending on whether the passenger on board is close or far.

  The first feature of the game of this embodiment is a passenger display method. A passenger display method according to this embodiment will be described with reference to the game screen of FIG.

  Players need to find passengers quickly while driving a taxi. A number of persons are displayed on the screen, but not all persons displayed on the game screen are passengers, and specific persons are passengers. For this reason, passengers are distinguished from other persons and displayed prominently on the game screen. As shown in FIG. 12, a cross-shaped conspicuous color, for example, a red mark 204 is displayed on the head of the passenger 202, and a cylindrical spot 206 shining so as to make the passenger 202 stand up is displayed. Thus, the player can easily go to the position of the passenger 202 by operating the taxi 200.

  The second feature of the game of the present embodiment is a method for displaying a direction instruction to the destination. A method for displaying a direction instruction to a destination in the present embodiment will be described with reference to FIGS.

  The player operates the taxi 200 toward the destination instructed to place the passenger 202 on his taxi 200. It is necessary to inform the player of the destination. In this embodiment, arrows 208 and 210 as shown in FIG. 13 and FIG. 14 are displayed as direction indicating objects in the screen. The player can reach the destination by traveling in the direction indicated by the arrow 208.

  In this embodiment, the display method is changed to the direction instruction according to the distance between the current position of the taxi 200 and the destination.

  FIG. 13 shows a case where the distance between the current position of the taxi 200 and the destination is a predetermined distance or more. In this case, an arrow 208 along the road that is the travel path is displayed instead of an arrow in a direction that goes directly from the current position to the destination. This is because displaying an arrow in a direction that directly goes from the current position to the destination may confuse the player. By displaying the arrow 208 in the direction toward the destination along the traveling path, the player can correctly drive the taxi 200 toward the destination.

  FIG. 14 shows a case where the distance between the current position of the taxi 200 and the destination is close within a predetermined distance. In this case, an arrow 210 is displayed in a direction that goes directly from the current position to the destination regardless of the direction of the travel path. This is because the destination 220 is also displayed on the screen when it is close, so that it is easier for the player to display the arrow 210 in a direction that goes directly to the destination. By displaying the arrow 210 in the direction directly toward the destination, the player can correctly drive the taxi 200 toward the destination.

  Furthermore, the colors of the arrows 208 and 210 to be displayed are changed depending on whether the distance between the current position of the taxi 200 and the destination is a predetermined distance or more and a distance within a predetermined distance. For example, a blue arrow 208 in FIG. 13 and a red arrow 210 in FIG. 14 inform the player that the direction instruction mode has been changed.

  As a method of notifying the player that the direction instruction mode has been changed, in addition to the method of changing the color of the arrow, the shape of the arrow can be changed, the arrow can be blinked, or as shown in FIGS. The display method may be changed. Further, during the game, the player may be notified by sound, or the background music may be changed.

  As a condition for changing the direction instruction mode, in the above-described specific example, it is determined by a predetermined distance between the current location and the destination. However, a constant distance may be used regardless of the destination, and the distance may be set according to the destination. It may be changed. For example, the predetermined distance is lengthened in the case of a destination with a good view, and the predetermined distance is shortened in the case of a destination with a bad view. Further, the distance may be determined in consideration of the configuration of the road near the destination.
