Description

  The present invention relates to a game control technique, and more particularly to a game control program, a game device, and a game control method for controlling a game for moving an object in a game field.

  A so-called “falling object puzzle” game in which a plurality of objects are dropped on the game field and the objects are arranged and deleted so as to satisfy a predetermined condition is gaining popularity.

  There are various types of fallen puzzle games that have been devised in terms of the shape and arrangement of objects, but there is a need for a more novel and entertaining fallen puzzle-like game.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a game control technique with higher entertainment.

  One embodiment of the present invention relates to a game control program. The game control program includes a function for arranging an object in a three-dimensional space provided in a game field, a function for simulating a physical phenomenon on a two-dimensional plane onto which the three-dimensional space is projected, and a simulated physical phenomenon. And a function of applying the above to an object in the three-dimensional space.

  It should be noted that any combination of the above-described constituent elements and a representation of the present invention converted between a method, an apparatus, a system, etc. are also effective as an aspect of the present invention.

  According to the present invention, a more entertaining game control technique can be provided.

  The game device according to the embodiment provides a game in which objects are moved and objects collide with each other in the game field. In this game, the movement of the object, the deformation due to the collision, etc. are all calculated by physical calculation after setting the physical quantity of the object and the force acting on the object.

  The game according to the embodiment is similar to a so-called “falling object puzzle” in which objects are dropped and stacked in the game field, but differs from the conventional falling object puzzle game in various respects. First, as described above, all movement of an object is calculated by physical calculation, so the object is governed by the laws of physics, from when the object is dropped in the game field to when it is stacked after dropping. Is done. Here, when the object is falling in the game field, the player can adjust the drop position by moving the object left and right, but if the object is naturally dropped by physics calculation, the drop speed will be too fast The player cannot operate. Therefore, in this embodiment, in order to adjust the falling speed of the object, a virtual buoyancy is set for the object, and the speed is adjusted so that the player can operate it.

  In a typical falling object puzzle, objects are erased from the game field by arranging a plurality of objects of the same type vertically and horizontally, but in the game of this embodiment, an object collides with another object. Thus, the volume is reduced by dividing or crushing the object. Also, items for burning or disassembling the object are prepared, and the object is erased from the game field using those items.

  In the present embodiment, since a three-dimensional object is accumulated in a three-dimensional game field, the arrangement of the objects is determined three-dimensionally by physical calculation, but a game is used to control the burning of the object. When simulating the temperature distribution in the field, the temperature distribution in the two-dimensional plane is calculated ignoring the temperature distribution in the depth direction. Thereby, it is possible to reduce the calculation load while minimizing the influence on the game. In addition, since the physical phenomenon is simplified and simulated, it is easy for the player to understand.

  FIG. 1 shows a configuration of a game apparatus 10 according to the embodiment. The game apparatus 10 includes a controller 20, an input receiving unit 30, a control unit 40, an object database 60, a distribution data holding unit 62, a screen generation unit 66, and a display device 68. In terms of hardware components, these configurations are realized by a CPU of a computer, a memory, a program loaded in the memory, and the like, but here, functional blocks realized by their cooperation are illustrated. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  The input receiving unit 30 receives a control signal input from the controller 20 operated by the player. The control unit 40 controls the behavior of the object in the game field based on the operation input from the player received by the input receiving unit 30, and advances the game. The screen generation unit 66 generates a game screen controlled by the control unit 40 and causes the display device 68 to display the game screen.

  FIG. 2 shows an example of a screen displayed on the display device. A game field 91 in the shape of a trash can is provided near the center of the screen, and objects 93 are stacked inside the game field 91. On the upper right of the screen, a belt conveyor 92 is displayed for displaying a state in which the objects that fall next are sequentially conveyed. In the lower right of the screen, an object information column 97 for displaying information of the object 93 that will fall next is provided. In the upper left of the screen, there is provided a saving place 94 for temporarily saving the objects in the order of dropping without dropping them. In the lower left of the screen, a temperature column 95 indicating the temperature inside the game field 91 and an oxygen column 96 indicating the amount of oxygen are provided. In addition, a character 98 that functions to take out an object existing below the game field 91 to the outside of the game field 91 is displayed at the bottom of the screen.

  The object database 60 stores data of objects arranged in the game field. FIG. 3 shows an example of internal data of the object database 60. The object database 60 is provided with an object ID column 70, a position column 71, a direction column 72, a shape column 73, and a status column 74. The object ID column 70 stores IDs of objects stacked in the game field 91. The position column 71 stores three-dimensional coordinates indicating the position of the center of gravity of the object. The direction column 72 stores a three-dimensional vector indicating the direction of the object in a state where the objects are stacked. The shape column 73 stores data indicating the shape of the object. As described above, in the game of the present embodiment, the object is deformed by collision between objects, but if the object shape is faithfully modeled and deformed by physical calculation, the calculation load becomes very high. Several types of shape data are prepared in advance according to the degree of deformation, and are deformed stepwise by collision. The status column 74 stores data indicating the state of the object. Examples of the object status include “normal”, “combusting”, “decomposing”, “falling”, and the like. In addition, the object database 60 stores data such as shape data and physical quantity of each object, data of force acting on the object, physical quantity of the object and adjustment amount of the force.

  The distribution data holding unit 62 stores data for simulating the physical quantity distribution in the game field. FIG. 4 shows an example of internal data of the distribution data holding unit 62. The distribution data holding unit 62 is provided with a mesh ID column 80, a position column 81, a temperature column 82, and a status column 83. The mesh ID column 80 stores the mesh ID when a two-dimensional game field obtained by projecting the three-dimensional game field 91 onto a two-dimensional plane is divided into meshes. Here, a projection of the game field 91 on a two-dimensional plane parallel to the side surface displayed on the display screen shown in FIG. 2 is a two-dimensional game field. That is, what is visible on the display screen is a two-dimensional game field. The position column 81 stores two-dimensional coordinates indicating the position of the mesh. As described above, in the present embodiment, when simulating the temperature distribution, the depth distribution in the three-dimensional game field 91 is ignored, so the coordinates in the depth direction are omitted. Therefore, the objects overlapping in the depth direction are considered to be at the same position. The temperature column 82 stores the temperature of the mesh. The temperature of the mesh is simulated and updated by the temperature distribution simulator 44 as will be described later. The status column 83 stores data indicating the mesh state. Examples of the status of the mesh include “combusting”, “submerged”, and “mycelium growth”.

  The game control unit 41 executes a game program and controls the progress of the game. Specific operations will be described later.

  The physics calculation engine 42 calculates motion such as movement, rotation, and collision of the object according to the motion equation. For example, the physics calculation engine 42 determines the object weight and friction coefficient for an object suspended on the belt conveyor 92, an object falling in the game field 91, and an object stacked in the game field 91. Are read out from the object database 60, and the behavior of the object is calculated by physical calculation by applying a drag force caused by gravity or air.

  The physical quantity adjusting unit 43 refers to the object database 60 and acts on the physical quantity of the object and the object so that a desired movement is realized when the object moves different from the actual physical law. Adjust the force. Specifically, when the game control unit 41 drops the object from above the game field 91, the game control unit 41 reduces the falling speed to a predetermined speed and drops the object at a constant speed. A vertical upward force is applied. This can be considered that a larger buoyancy or drag force is applied to the object than usual, or it can be considered that gravity is reduced more than usual. At this time, the physical quantity adjustment unit 43 changes the weight of the object to a predetermined value in order to adjust the drag caused by air. Further, the physical quantity adjustment unit 43 may change the volume of the object to a predetermined value in order to adjust the buoyancy of the object.

  In the conventional game, when an object falls within the game field 91, the still image of the object is moved downward to represent a state of falling. However, according to the technique of the present embodiment, the object falls. Since the behavior of the object is calculated by physics while the object is moving, when the object is moved to the left or right, the object shakes to the left or right, or the object collides with another object to move the other object. Can be deformed. Thereby, the behavior of the object with higher realism can be reproduced, and the entertainment of the game can be improved.

  The temperature distribution simulator 44 simulates the temperature distribution in the game field 91. In the game according to the present embodiment, an ignition item for burning an object accumulated in the game field 91 is prepared, and when the ignition item is arranged in the game field 91, surrounding objects have predetermined combustion conditions. The object burns when it is met. The temperature distribution simulator 44 simulates changes in the temperature distribution in the game field 91 due to the burning of ignition items and objects.

  The temperature distribution simulator 44 refers to the object database 60, acquires a three-dimensional position of a heat source such as an ignition item or a burning object, and specifies the position of the mesh corresponding to that position. The temperature distribution simulator 44 sets the temperature of the mesh with the heat source to a predetermined temperature.

  The temperature distribution simulator 44 calculates the temperature of each mesh at a predetermined timing, for example, an interval at which the screen generation unit 66 generates a screen, and updates the data in the distribution data holding unit 62. The temperature distribution simulator 44 may set the temperature propagation speed of an object or air and calculate the temperature distribution by physical calculation, or more simply calculate the temperature statistics of the surrounding mesh, It is good also as the temperature in the next timing of the said mesh.

  When the temperature distribution simulator 44 calculates the temperature of each mesh, the temperature distribution simulator 44 determines whether or not each object arranged in the game field 91 burns. The temperature distribution simulator 44 acquires a three-dimensional position of each object from the object database 60 and specifies a mesh corresponding to the position. The temperature distribution simulator 44 acquires the ignition temperature of each object from the object database 60 and confirms whether the temperature of the corresponding mesh exceeds the ignition temperature. If the mesh temperature exceeds the ignition temperature and the oxygen amount in the game field 91 is equal to or greater than a predetermined value, the temperature distribution simulator 44 determines that the object has started combustion, and the object database 60 and distribution The status of the data holding unit 62 is updated. When a part of the object starts to burn, the other part of the object may be considered to have started to burn, and it may be determined whether the object burns for each mesh.

  Since the game field 91 is a three-dimensional space, the temperature is distributed in the depth direction, and strictly speaking, the temperature propagation in the depth direction must be taken into consideration. Is displayed from the side, so the temperature distribution in the depth direction is not very important. In the game field 91, an object is not only stacked on an object that has already been stacked, but may fall in front of or behind the object, so that a plurality of objects may be arranged in the depth direction. However, only the foreground object is displayed on the screen. For this reason, even if the temperature is distributed in the depth direction, it is complicated and it is difficult for the player to understand. Accordingly, the temperature distribution simulator 44 simulates the temperature distribution on a two-dimensional plane, assuming that the depth direction is the same temperature. As a result, the calculation load can be reduced and the physical phenomenon can be expressed in an easy-to-understand manner for the player.

  The mycelia growth simulator 45 simulates mycelia growth in the game field 91. In the present embodiment, a special mycelium that disassembles an object grows in the game field 91, and an object that has been in contact with the mycelia for a predetermined time is disassembled and deleted from the game field 91. The game control unit 41 drops mycelial spores for decomposing the objects accumulated in the game field 91 and water in a container such as a bucket into the game field 91 as items at a predetermined frequency. When the spore item is arranged in the game field 91 and the spore is immersed in water, the mycelium grows from the spore, and the object is decomposed by the mycelium.

  The mycelia growth simulator 45 calculates mycelia growth for each mesh at a predetermined timing, for example, an interval at which the screen generator 66 generates a screen. The mycelium growth simulator 45 may calculate mycelia growth based on parameters such as the temperature, oxygen amount, and mycelia growth speed in the game field 91. More simply, for example, spores are immersed in water. In this case, the mycelium may be grown in a random direction by 1 mesh per predetermined number of frames.

  Similarly to the temperature distribution simulator 44, the mycelia growth simulator 45 ignores the hyphal growth in the depth direction and simulates the hyphal growth in a two-dimensional plane. Thereby, it is possible to reduce the calculation load while minimizing the influence on the game.

  Next, details of the game operation will be described with reference to the drawings. FIG. 5 shows an example of a screen displayed on the display device. The game control unit 41 selects an object to be dropped on the game field 91 at predetermined time intervals from among the objects for which shape data is prepared in advance, and sequentially suspends the selected objects on the belt conveyor 92. The state of being transported to the game field 91 by 92 is displayed. The object 99 that has arrived in the order of falling on the game field 91 is disposed at the center position above the game field 91 and is temporarily stopped. When the timing for dropping the object 99 arrives, the game control unit 41 causes the physical quantity adjustment unit 43 to adjust the physical quantity, and then causes the physics calculation engine 42 to calculate how the object 99 falls, and causes the screen generation unit 66 to display the screen. Is generated.

  The game control unit 41 receives an instruction from the player while the object 99 is falling, and moves or rotates the object 99 left and right. The motion of the object at this time is also calculated by the physical calculation engine 42. If the object 99 touches another object or the wall or bottom surface of the game field 91 and does not move for a predetermined time or longer, the game control unit 41 fixes the object at that position and registers it in the object database 60. To do.

  FIG. 6 shows an example of a screen displayed on the display device. The player can deform the object 93 by causing the heavy object 99 to collide with the easily deformable object 93. The game control unit 41 calculates the energy of collision between the object 99 and the object 93 and determines the degree of deformation of the object according to the energy. The game control unit 41 reads new shape data from the object database 60 according to the determined degree of deformation, and updates the object image. Further, the shape column 73 and the position column 71 of the corresponding object in the object database 60 are updated.

  FIG. 7 shows an example of a screen displayed on the display device. When the ignition item 87 is arranged in the game field 91, the temperature distribution simulator 44 starts simulating the temperature distribution in the game field 91. An ignition temperature is set for each object, and when the temperature of the mesh on which the object is placed exceeds the ignition temperature, the game control unit 41 burns the object 93 as shown in FIG. The status column of the distribution data holding unit 62 is updated. When the game control unit 41 applies the temperature stored in the distribution data holding unit 62 to the object, it is assumed that the directions perpendicular to the display screen are all the same temperature. The game control unit 41 reduces the oxygen amount in the game field 91 at a predetermined speed when the object in the game field 91 is burning. The game control unit 41 stops the combustion of the object when the amount of oxygen in the game field 91 falls below a predetermined value.

  FIG. 9 shows an example of a screen displayed on the display device. When the spore item 88 is arranged with water stored in the game field 91, the mycelium growth simulator 45 starts simulating mycelial growth. Conditions are set for each object to be decomposed by the mycelium. As shown in FIG. 10, when the hyphae 89 grow on the mesh on which the object is arranged and a predetermined condition is satisfied, the game control unit 41 disassembles the object and causes it to disappear from the game field 91.

  The game control unit 41 drops important items that should not be deformed or disappear in the game field 91 at a predetermined frequency. If this item remains below the game field 91 without being deformed for a predetermined time or longer, the game control unit 41 displays a state in which the character 98 removes the item from the game field 91 and deletes it from the object database 60. . When this item disappears due to combustion or decomposition, the game control unit 41 causes a plurality of objects to fall simultaneously on the game field 91 as a penalty.

  In the above, this invention was demonstrated based on the Example. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to each component and combination of processing processes, and such modifications are within the scope of the present invention.
