(Game contents)
Next, a game provided by the game program of this embodiment will be described.

  This game is an online multiplayer game in which a plurality of player characters hunt in the same three-dimensional virtual game space. In the virtual game space, there is a plaza where there are many facilities where player characters can use. Examples of facilities include an inn, a weapon shop, and an armor shop. In the square, information such as the name of the facility and the name of the NPC (non-player character) is displayed in the vicinity of the facility and the NPC. FIG. 2 shows a display example of a plaza in the virtual game space. In the example of FIG. 2, the player character 50 is facing the square. Labels 70A to 70H indicating the name of the facility and the name of the NPC are displayed in the vicinity of the facility objects 60A to 60F and the NPC objects 62G and 62H in the square.

  In the example of FIG. 2, label 70B and label 70G, label 70B and label 70C, label 70H and label 70C, and label 70H and label 70D overlap. Further, the label 70A is displayed so as to protrude from the game screen. Furthermore, although the object 60F is hidden behind the object 64 in front, the label 70F of the object 60F is displayed in front of the object 64.

  In the present embodiment, as shown in the display example of FIG. 3, the positions of the overlapping labels 70B, 70C, 70D, 70G, and 70H and the protruding label 70A are shifted and hidden by the object 64 in order to make the labels 70A to 70H easier to see. The display mode (transparency, color, size, font, etc.) of the label 70F of the object 60F was changed. By changing the display mode, the object 60F indicated by the label 70F cannot be seen, but it can be seen that the object 60F exists in the direction of the label 70F. In FIGS. 2 and 3, labels 70A to 70H are indicated by square frames, but on an actual game screen, character strings indicating facilities and NPCs are displayed. Alternatively, a mark or icon indicating a facility or NPC may be used.

(Game device)
Next, a game apparatus configured by a game machine executing the game program of the present embodiment will be described.

  FIG. 4 is a functional block diagram showing a configuration of a game device configured by the game program of the present embodiment. The game apparatus 10 shown in FIG. 4 includes a label position calculation unit 11, an overlap determination unit 12, a display state determination unit 13, a label position correction unit 14, and a display unit 15.

  The label position calculation unit 11 calculates the display position of the label of the object existing within the angle of view of the virtual camera that captures the virtual game space. 2 and 3, the virtual camera exists behind the player character 50 and photographs a square. The reference point of the label is set to predetermined coordinates in the virtual game space such as the upper part of the facility in the virtual game space or the overhead of the NPC. The label position calculation unit 11 converts the three-dimensional coordinates indicating the label position into two-dimensional coordinates on the plane of the game screen, and calculates the display position of the label on the game screen.

  The overlap determination unit 12 determines whether or not the labels overlap on the plane of the game screen from the label display position (coordinates) calculated by the label position calculation unit 11.

  The display state determination unit 13 determines a display state such as whether or not the labeled object is hidden behind another object. For example, the display state determination unit 13 determines that an object touched by the ray is a visible object (object to be drawn) by flying the ray from the virtual camera into the virtual game space. On the other hand, an object that does not touch a ray is determined as an invisible object (an object that is not drawn).

  The label position correction unit 14 corrects the label display position based on the label overlap determined by the overlap determination unit 12 and changes the label display mode based on the label display state determined by the display state determination unit 13. . For example, the label position correcting unit 14 shifts the display position of the label up and down when the label overlaps another label. Further, the label position correcting unit 14 does not display the label when the other object overlaps at least a part of the object indicated by the label, does not display the label, displays the label semi-transparently, and sets the color, font, and size of the label. Change the display mode of the label, such as changing or adding a mark or icon to the label.

  The display unit 15 displays the label on the game screen based on the correction result of the label position correction unit 14. After drawing the virtual game space, the display unit 15 displays the label so as to overlap the virtual game space. When the display position corrected by the label position correction unit 14 and the display position of the label in the immediately preceding frame are separated from each other by a predetermined distance, the display unit 15 The middle point of the display position is set as the display position of this label.

(Label processing)
Next, processing for determining the display position and display mode of the label will be described.

  FIG. 5 is a flowchart showing the flow of processing for determining the label display position and display mode.

  The label position calculation unit 11 selects one label for determining the display position (hereinafter referred to as “processing target label”) (step S11). In the present embodiment, labels that determine the display position are selected in order from an object that is within the angle of view of the virtual camera and is close to the virtual camera. For example, in the example of FIGS. 2 and 3, the label 70A of the object 60A closest to the virtual camera is first selected. Alternatively, priorities may be given to objects and labels, and the display positions of the labels may be determined in descending order of priority.

  For example, the priority of an important facility (a facility often used by players such as a player character's home, tool store, armor store, etc.) is increased. Conversely, the priority of those that are not important facilities may be increased. Since a label with high priority is processed first, it does not overlap with other labels, and the correction amount of the display position of the label becomes small. That is, a label with a high priority is displayed near the labeled object.

  Since the player often uses important facilities, the position of the facility can be recognized even if no label is displayed near the facility. However, the player does not accurately store the locations of facilities that are less frequently used. In this case, the label can be displayed near the facility by increasing the priority of the label of the facility that is not frequently used.

  In step S11, only an object existing within a predetermined distance from the player character or the virtual camera may be selected as a processing target label. For example, with respect to an object for displaying a label, the range for displaying the label can be switched by an operation of the player for “only an object within 10 m from the player character”, “only an object within 20 m from the player character”, and “all objects”. It may be.

  The label position calculation unit 11 converts the three-dimensional coordinates indicating the position of the processing target label into the two-dimensional coordinates on the game screen, and calculates the display position of the label on the game screen (step S12).

  The overlap determination unit 12 determines whether the processing target label overlaps with another label (step S13). The label occupies a rectangular area corresponding to the length of the character string with reference to the two-dimensional coordinates calculated by the label position calculation unit 11. The overlap determination unit 12 checks the label overlap by determining whether or not the rectangular area of the processing target label overlaps the rectangular area of another label.

  When the processing target label overlaps with another label, the label position correction unit 14 moves the display position of the processing target label up or down (step S14).

  FIG. 6 shows how the label display position is shifted. Since the label 70B to be processed overlaps the label 70G, the display position of the label 70B is moved upward. At this time, as the moving direction (up or down) of the label 70B, the shorter one of the distance moving up and the distance moving down is selected. Depending on the situation, for example, when the label 70B cannot be moved up and down, or when the movement distance is shorter when moved left and right, the label 70B may be moved left and right to eliminate the overlap of the labels 70B and 70G. Note that the display position of the label 70G that has already been processed and whose display position has already been determined does not move.

  In addition, about the label of the facility displayed in an overlapping manner, it is allowed to display the labels overlapping each other, and the labels may be displayed alternately. For example, the label may be alternately blinked every second. In step S13, it is determined whether or not a part of the processing target label protrudes outside the game screen. In step S14, the display position is moved to the left and right so that the entire processing target label is within the game screen. Also good. FIG. 7 shows a state in which the display position of a label that partially protrudes outside the game screen is shifted. In the example of FIG. 7, since a part of the label 70A protrudes outside the game screen, the display position of the label 70A is moved to the right so that the entire label 70A fits within the game screen. As a result of moving the label 70A to the right, if it overlaps with another label, the display position of the label 70A is further moved up and down.

  When the display position of the processing target label is determined, the display state determination unit 13 determines whether or not the object (facility or NPC) indicated by the processing target label is hidden by another object (step S15). The display state determination unit 13 checks the line of sight from the virtual camera to the object indicated by the processing target label, and determines whether or not the object is hidden by another object. Alternatively, the line of sight from the virtual camera to the three-dimensional coordinates indicating the position of the processing target label may be checked.

  When the object indicated by the processing target label is hidden, the label position correcting unit 14 changes the display mode of the processing target label (step S16). For example, a label that is hidden by an object is displayed in a translucent manner, displayed in a different color, or displayed in a different font or size. Further, the transparency and size of the label may be changed according to the distance from the virtual camera to the object.

  In the display example of FIG. 3, since the object 60F is hidden behind the object 64 and cannot be seen, the label 70F indicating the object 60F is made translucent. Note that the display mode of the label 70E of the object 60E partially overlapping the object 64 may also be changed. At this time, the display mode may be changed according to the ratio of the objects being hidden, such as when all the objects are hidden or when more than half of the objects are hidden. For example, the transparency of the label 70E is made lower than the transparency of the label 70F.

  Further, the number of uses of the object indicated by the processing target label may be determined in step S15, and the display mode may be changed in accordance with the number of uses in step S16. For example, the display mode may be changed so that the label does not stand out by reducing the color of the facility label according to the number of times the facility is used, increasing the transparency, or reducing the size. Conversely, the display mode may be changed so that the label stands out. Alternatively, the label of the facility that has never been used may not be displayed, and the label of the facility that has been used more than a predetermined number may not be displayed.

  It is determined whether or not all labels existing within the angle of view of the virtual camera have been processed (step S17). If there is an unprocessed label, the process returns to step S11 to select the next label.

  Through the above processing, the labels do not overlap with each other, and the label of the invisible object is displayed in a different form from the label of the visible object.

(Modification)
Next, a modification of this embodiment will be described.

  FIG. 8 is a diagram illustrating an example in which labels of objects outside the angle of view of the virtual camera are displayed at the end of the game screen.

  In this modification, the labels 70S to 70Z of the objects that cannot be seen are displayed at the end of the game screen. The object label displayed when the virtual camera is directed to the right is displayed at the right end of the game screen, and the object label displayed when the virtual camera is directed to the left is displayed at the left end of the game screen. The labels 70 </ b> S to 70 </ b> Z are displayed semi-transparently, displayed in a small size, or change the display mode from other labels.

  When the number of labels to be displayed at the end of the game screen is large, the labels may be overlapped and displayed as labels 70Y and 70Z.

  By displaying the labels 70S to 70Z of the invisible objects on the edge of the game screen, the player can roughly know the invisible facilities and the position of the NPC.

  FIG. 9 shows an example of a game screen in which the object 60F and the label 70F hidden by the object 64 are visible. In the example shown in the figure, the display of the object 64 is erased, the object 60F is displayed, and the transparency of the label 70F is changed.

  When the player performs a predetermined operation (touching an object on the game screen, operating the cursor to select an object, operating a button, etc.), the object whose label is hidden is erased or made transparent. For example, when the player performs a predetermined operation on the object 64, the display of the object 64 is turned off. Alternatively, the display of the object 64 may be erased when a predetermined operation is performed on the label 70F displayed in a semi-transparent state. Alternatively, when there is a hidden object 60F, the display of the object 64 may be erased so that the object 60F can be seen only by operating a predetermined button.

  As described above, according to the present embodiment, the label position calculation unit 11 converts the three-dimensional coordinates of the label indicating the object in the three-dimensional virtual game space into the two-dimensional coordinates of the game screen, and the label position The correction unit 14 moves the two-dimensional coordinates of the label when the label overlaps another label on the game screen, and the label position correction unit 14 displays the label when the object indicated by the label cannot be seen by another object. By changing the mode, a label indicating an object in the three-dimensional virtual game space can be displayed in an easy-to-understand manner.
