Description

  The present invention relates to a game program and a game apparatus for a video game that operates a character in a three-dimensional virtual space.

  Conventionally, there are video games of various genres that are played by operating a player character in a three-dimensional virtual space. For example, a game as shown in Patent Document 1 is known.

  In many of these games, as in Patent Document 1, a player character encounters an enemy character, fights, and advances a game story. Also, recently, not only the method of proceeding while fighting with enemy characters, but also the method of proceeding while hiding in the shadow so as not to encounter the enemy character, the method of proceeding while searching for another route where there is no enemy, There is also a known system that allows selection of a plurality of methods for game capture.

JP 2004-267247 A

  By the way, when adopting a system that allows the selection of a plurality of methods as described above, the degree of freedom of the player is increased, but for example, a beginner player, for example, is confused as to which method can be used here, Eventually, the inconvenience of not being able to enjoy the high degree of freedom has arisen.

  Accordingly, an object of the present invention is to provide a game program and a game device that increase the degree of freedom of the player and can be easily played even by beginners.

A game program according to the present invention causes a computer (1) having an input means (3) to operate a player character (PC) in a virtual three-dimensional space based on a command input from the input means. In the game program (70) for executing the game by moving the player character from the first coordinate position (A) to the second coordinate position (B) in the three-dimensional space, in the virtual three-dimensional space, A main route (MR) from the first coordinate position to the second coordinate position, and at least one sub-route (SR) in which all or part of the route is different from the main route, and A procedure for installing a sign object (25) at a position (22A) that branches to the sub-route in the main route, and the virtual tertiary A procedure for arranging at least one object object (OB) and at least one enemy character (NPC) in the main route of the space, and the enemy character based on a predetermined action rule When control is performed to act within the main route, and the mutual relationship between the enemy character, the object object, and the player character satisfies a predetermined condition, the enemy character is directed toward the player character. And controlling the player character in the virtual three-dimensional space on the basis of a procedure for making the player act so as to attack and a command input from the input means, and the player character, the object object, and the input When the relationship satisfies a predetermined condition based on the relationship with the command input from the means Is based on the relationship between the player character and the sign object, the procedure for causing the player character to act so as to hide the object, and if the relationship satisfies a predetermined condition, A procedure for highlighting the display mode of the sign object, and a procedure for moving the player character to the sub-route when the player character accesses the sign object, are performed.

The game device according to the present invention comprises a computer having input means, and operates a player character in the virtual three-dimensional space based on a command input from the input means, thereby causing the first of the virtual three-dimensional space to be operated. In the game device, in which the game is executed by moving the player character from the coordinate position to the second coordinate position, the first to third coordinate positions are reached in the virtual three-dimensional space. Route setting means (53) for setting a main route and at least one sub route that is different from all or part of the main route, and a marker object at a position of the main route that branches to the sub route And object placement means (54) for placing at least one body object on the main route. A character placement means (55, 56) for placing the player character so as to be able to act in the virtual three-dimensional space, and placing at least one enemy character on the main route; If the mutual relationship between the enemy character, the object object, and the player character satisfies a predetermined condition, the enemy character, the object object, and the player character are controlled to act on the main route based on the determined action rule. Based on an enemy character control means (56) that causes the character to act so as to attack the player character, and based on a command input from the input means, the player character is controlled in the virtual three-dimensional space. , Input from the player character, the object object, and the input means And a player character control means (55) for causing the player character to act so as to hide itself from the object object, when the relationship satisfies a predetermined condition based on the relationship with the received command, and the player A sign object control means (54) for highlighting a display mode of the sign object when the relation satisfies a predetermined condition based on the relation between the character and the sign object; The player character control means moves the player character to the sub-route when the player character accesses the sign object.

  According to the present invention, when the player character (PC) approaches the accessible sign object (25), the sign object is highlighted, so that an accessible location can be immediately identified, and even a beginner can use the sub route. (SR) can be easily searched.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the game device 1 which is a computer is a so-called stationary home video game machine. The game apparatus 1 has a main body 2, and a controller 3 as an input means is connected to the main body 2 with a cable or the like. The main body 2 is provided with a liquid crystal monitor 5 which is an image output device such as a television connected by a cable or the like. The main body 2 incorporates an arithmetic device, a storage device, and the like (not shown), and an optical medium 7 as a storage medium is mounted in a readable manner with respect to a drive 4 provided in the main body 2. . Note that the game apparatus 1 illustrated in FIG. 1 is merely an example of the game apparatus according to the present invention, and the game apparatus of the present invention may be other than that shown in FIG. For example, the game device of the present invention may be configured by a general personal computer, or configured by a portable game machine driven by a battery, a smartphone, a portable multimedia player, a cellular phone, a PDA, or the like. Also good. Alternatively, the game device can be configured by an arcade game machine or the like.

  Next, the game apparatus 1 that executes the game program 70 will be described in terms of its functions with reference to FIG. As shown in FIG. 2, the game apparatus 1 includes a main control unit 50 as an arithmetic device, a memory unit 51 and a drive 4 as a storage device, an input control unit 52 for inputting a signal from the controller 3, and an arithmetic device. A three-dimensional space setting unit 53 for setting a three-dimensional space, an object control unit 54 for controlling a display mode when an object is arranged and rendered in the virtual three-dimensional space, and a player character composed of a three-dimensional object A player character control unit 55 that controls the action of the player character, and arranges an enemy character composed of a three-dimensional object so as to be able to act in the virtual three-dimensional space. Enemy character control unit 56 that controls the action of the character, the virtual three-dimensional space described above was shot with a virtual camera Image output control unit 57 to display output to the liquid crystal monitor 5 to draw the image, and a game progress control unit 58 that controls the game progress based on the game program 70.

  An execution procedure of the game program 70 executed in the game apparatus 1 configured as described above will be described. First, the game apparatus 1 receives an activation operation by the player, reads the game program 70 stored in the optical medium 7 through the drive 4 and executes it, thereby performing a game progress process (ST01) as shown in FIG. It is executed by the game progress control unit 58. For example, it is assumed that the content of the game to be processed here is a first person shooting game (the camera position is at the eye position of the player character). The first person shooting game is merely an example, and the game to which the present invention is applied is a pseudo first person shooting game (the camera position is not the position of the player character's eyes but the player character's shoulder, head, or the like) ), Third-person shooter games (where the camera position is behind or to the side of the player character and the player character's whole body or upper body is displayed), other shooter games, role-playing games, adventure games, and other genre games It may be. In the first person shooting game shown in this example, as shown in FIG. 4, the game purpose is that the player character moves from the first point A to the second point B in the game world set in the virtual three-dimensional space. It has become. The other contents in the game and the specific contents of the game progress are the same as those of the well-known first person shooter game and the like, and will not be described individually.

  Next, as shown in FIG. 3, the player character PC is placed at the first point A (ST02). Note that the game progress control unit 58 always determines whether or not the player character PC has reached the second point B (ST03). If it is determined that the player character PC has reached the second point B, the game proceeds. Clear the purpose. If the player has not yet reached the second point B, the player operates the player character PC via the controller 3 (ST04). In the game world in the virtual three-dimensional space, as shown in FIG. 4, the main route MR (solid arrow in FIG. 4) passing through the room 21 of the building is set from the first point A to the second point B. An air duct 22 is provided at a position corresponding to the ceiling or the like of the room 21. A sub route SR (broken arrow in FIG. 4) is set as a route passing through the air duct 22. Equipment, structures, and objects such as the room 21 and the air duct 22 are composed of CG objects in the virtual three-dimensional space. However, the coordinate data, CG data, and the like are not necessarily loaded as a whole into the memory unit 51, and necessary portions are loaded in a replaceable manner as necessary, as will be described later. That is, when the player character PC is arranged at the first point A, as shown in FIG. 5, a predetermined position (boundary in FIG. 5) traveled along the main route MR from the first point A toward the second point B. The map data related to the first area AR1 up to C) is loaded into the memory unit 51. Map data refers to data relating to a background, an object, a player character PC, an enemy character NPC, etc. included in a certain area in the virtual three-dimensional space.

  Further, when the player character PC reaches a predetermined position before the boundary C from the first point A, it is an area ahead of the boundary C (area from the boundary C to the boundary D in FIG. 5) as shown in FIG. Loading of map data related to the second area AR2 is started, and the loading start position is adjusted so that loading is completed when the player character PC enters the second area AR2. Similarly, when the player character PC reaches a predetermined position before the boundary D, loading of map data relating to the third area AR3, which is an area from the boundary D to the second point B, is started, and the player character PC starts the third area. The loading start position is adjusted so that loading is completed when entering AR3. Further, the map data relating to the area in the air duct 22 that is the sub-route SR, that is, the fourth area AR4 in FIG. 5, is loaded when the player character PC starts climbing the ladder 23 (see FIGS. 4 and 5) that reaches the sub-route SR. And the speed and the like of climbing the ladder 23 are adjusted so that the loading is completed when the player character PC enters the fourth area AR4 (that is, the sub route SR). Further, when the player character PC moves through the air duct 22 and reaches a predetermined position before the exit 22B on the third area AR3 side, loading of map data relating to the third area AR3 is started, and the player character PC starts from the exit 22B. The loading start position is adjusted so that loading is completed when the ladder 26 is dismounted.

  The setting of the areas AR1, AR2, AR3, AR4, etc. when loading the map data described above was performed by a method of dividing according to the type of data used. For example, in the first area AR1, data on events, tutorials, ladders 23, covers 25, etc. at the first point A is required, and in the second area AR2, the battle between the object object OB, the enemy character NPC, and the player character PC is required. In the third area AR3, data on the event at the second point B, the ladder 26, and the like are necessary, and in the fourth area AR4, data on the air duct 22 is necessary. However, the method of taking each area is merely an example, and it is possible to set the area by other methods.

  Subsequently, as shown in FIG. 3, the player inputs an instruction from the controller 3, and the player character control unit 55 causes the player character PC to perform an action such as movement while applying a preset motion (ST04). When the player character PC enters the second area AR2 of FIG. 5, the enemy character control unit 56 arranges the enemy character NPC in the room 21 and controls its action. The enemy character NPC is a so-called non-player character in which an action is controlled only by a program by the enemy character control unit 56 rather than an operation from the player. The enemy character NPC is controlled by the enemy character control unit 56 and is walking in the room 21 as shown in FIG. The action of the enemy character NPC is determined by a program called AI (population intelligence). The enemy character control unit 56 constantly monitors the mutual relationship between the enemy character NPC and the player character PC (ST05 in FIG. 3). For example, as shown in FIG. 6, in front of the enemy character NPC and within a radius of 3 m on the scale of the game world (the number 3m is just an example), and between the enemy character NPC and the player character PC If there is no object that blocks the enemy character NPC, it is determined that the enemy character NPC has noticed the presence of the player character PC (indicated by a black circle in FIG. 6), and the enemy character NPC is attacked toward the player character (for example, Start shooting with a gun). In this case, the player character PC enters a battle with the enemy character NPC (ST06 in FIG. 3). For example, if the player character PC is defeated in a battle by performing an attack with a gun or the like, or an attack by fighting, the game is over (ST07 in FIG. 3). If the player character PC wins in battle, the player character PC continues to move toward the second point B, which is the destination (ST03 in FIG. 3).

  Alternatively, when the player operates the player character PC to move it to the vicinity of the object object OB such as a cabinet or a desk and presses a specific button of the controller 3 (or tilts the lever in a direction to press the object), the player character As shown in FIG. 7, the control unit 55 performs a control such as squatting the player character PC and taking a pose that hides the body object OB (this mode is referred to as stealth). ). When becoming stealth, the camera viewpoint may be controlled to move from the first person to the third person, and by automatically changing the camera viewpoint in this way, even if it is a beginner, it is effective from the enemy character NPC. The operation for concealing yourself becomes easy. Basically, during stealth, while controlling the camera in the third person, if you want the player character PC to perform a sniper from inside the stealth, switch the camera viewpoint to first person (or pseudo first person) to improve operability It is also effective to make it.

  During stealth, as shown in FIG. 6, in the above-described monitoring by the enemy character control unit 56 (ST05), the player character PC (white circle in FIG. 6) is located in front of the enemy character NPC and within a radius of 3 m on the scale of the game world. In this case, the object object OB exists in a form that blocks between the enemy character NPC and the player character PC. Therefore, the enemy character NPC is unaware of the presence of the player character PC. It is determined. Therefore, the player character PC hides itself from the object object OB for a while and waits for the enemy character NPC to go far away, and then returns from the state of hiding himself to the normal state (the state before hiding himself). In addition, the movement to the second point B can be advanced. Thus, an option of moving to the second point B without fighting with the enemy character NPC is also possible. For beginners, the risk of being defeated in a battle and being over the game is reduced, and the game is easier to clear.

  On the other hand, the player operates the player character PC to reach the vicinity of the inlet 22 </ b> A of the air duct 22. For example, in FIG. 4, the player character PC climbs the ladder 23 that reaches the entrance 22A. Near the inlet 22A of the air duct 22, a cover 25 configured as an object is attached. The object control unit 54 monitors the relative positional relationship between the position of the player character PC and the position of the inlet 22A of the air duct 22, and the relative position is within a radius of 3 m on the scale of the game world (the number 3m is an example) If this is the case, the highlight display is executed by illuminating the cover 25 or displaying it in a conspicuous color such as yellow or red that is easily distinguishable from surrounding colors. The player visually recognizes the highlight display and obtains a hint that the object is accessible. For example, the player goes to the vicinity of the cover 25 and presses a specific button of the controller 3 (or a specific lever). By performing the operation, the cover 25 is removed, and the operation of entering the air duct 22 ahead of the cover 25 is executed. The air duct 22 is a sub route SR with respect to the main route MR, and there is no enemy character NPC in the middle of the sub route SR. Note that the highlight display may be performed on another object such as the ladder 23 that is accessible. Further, the relative positional relationship between the player character PC and the position of the inlet 22A of the air duct 22 that is a condition for performing the highlight display may be other than the above-described conditions. For example, the area where the player character PC belongs to the inlet 22A The highlight display may be performed on the condition that it exists in the first area AR1.

  Thereafter, the player character PC proceeds through the air duct 22 (for example, from the viewpoint of the first person camera) by a predetermined operation by the controller 3, reaches the exit 22B near the second point B, and returns to the main route MR. With the option of taking the sub-route SR, there is no possibility that a battle with the enemy character NPC will occur in the movement in the air duct 22, so that even a beginner can move to the second point B relatively easily. In the above example, the air duct 22 is the sub route SR, but various other forms such as an attic and a back wall gap are possible as the sub route. In the above example, only one sub route is provided for one main route. However, a plurality of sub routes may be provided for one main route. Furthermore, a plurality of main routes themselves may be provided.

  It may be determined whether or not it is possible to move to the sub-route based on character status information, game play difficulty information, or game play time and number of times. In this case, when it is determined that the movement to the sub-route is impossible, the movement to the sub-route cannot be performed, so the map data of the sub-route is not read, and the relative between the marker object such as the cover 55 (entrance 22A) and the player character There is no position monitoring. Furthermore, even if the player character moves to the vicinity of the sign object and performs an operation, the action of entering the sub route does not occur. Alternatively, based on conditions such as character status information, game play difficulty information, or game play time and number of times, it is possible to determine whether or not the highlight display of the sign object is possible (although movement to the sub-route is possible). . When the above condition is satisfied, even if the character reaches the vicinity of the object, the object is not highlighted, so that the sub route search becomes difficult. In the case of an experienced player, there are cases where the player can enjoy the game without hints rather than the hints by highlight display.

  As in the above embodiment, there are multiple options such as battle with the enemy, stealth, and sub-route search, which increases the user's freedom, but which method can be used here even for beginner players etc. Is easy to recognize. In other words, if an enemy attacks, you will select a battle, and if you operate in the vicinity of the object, you will be in a pose that hides you, so you can operate intuitively, and when you approach an accessible object, it will be highlighted. Therefore, it is possible to easily search for a sub route.
