JP5235319B2 - Game machine that adjusts the elapsed time in the game according to the speed of the moving body - Google Patents

Description

  The present invention relates to a game machine in which the elapsed speed in a game is changed in accordance with the speed of the own vehicle in a video game.

Race game machines are installed in game centers and the like, and many players enjoy the race game.
When playing a racing game, the player sits on the seat in front of the game machine, operates the accelerator, brake, shift lever, etc. and manipulates the steering wheel to select the course and car between the computer car and other game machine cars. It will be a race. In addition, a time attack race or the like can be performed to update and record the lap time for the selected course.

Since the car runs at high speed in the race game, the background image flows according to the speed of the car.
A game device (Reference Document 1) has been proposed as providing a special effect that increases the reality on the screen. This is because a plurality of textures are prepared in image processing, a background image in which the moving body is stopped or in a low speed state is given to at least one of the first textures, and the moving body is slow in at least one second texture. By giving a background image when the vehicle is in the above running state, the background movement according to the vehicle running speed is not expressed, and the movement when the car is actually running cannot be expressed naturally. It solves the conventional problem.

By the way, you may hit a curve or the like during a race and accidentally operate the steering wheel or brake, and you may collide with a wall beside the road and stop. The player starts the car again from 0 km, and it takes time to increase the speed beyond the original speed.
In such a situation, even if the speed of the car increases, the game machine is configured so as not to change the elapsed speed of the game time as shown in FIG. In other words, the speed at which the game flows is constant regardless of the speed of the car. Therefore, as shown in FIG. 8, the screen flows in a constant proportional relationship with the speed of the car, and the sensation speed felt by the player in the game always feels proportional to the speed of the car.

Therefore, when the vehicle speed does not increase sufficiently, the player cannot obtain a sufficient refreshing feeling that matches the vehicle speed.
The object of the present invention is to increase the sensation speed of the moving object in the screen by making it progress faster than the normal game speed by speeding up the passage of time in the game when the speed of the moving object is not increased. It is to provide a game machine that can.

In order to achieve the above object, claim 1 of the present invention is directed to a moving body driving game machine in which a moving body advances on a predetermined course while a player operates the operation unit to increase or decrease the speed of the moving body. A storage unit that stores a moving body speed / decimation rate table that indicates a rate at which an image frame that is the background of the game screen is thinned out relative to the body speed, and a movement that is accelerated or decelerated by operating the operation unit by the player A moving body speed detecting means for detecting a body speed and a thinning rate determination for reading out an image frame thinning rate with respect to the moving body speed detected by the moving body speed detecting means with reference to the moving body speed pair thinning rate table and means, and control means, wherein if the speed of the moving object is less than the predetermined speed, performs the decimation of the frame image, the moving object If degrees is equal to or higher than a predetermined speed, and performs image display by stopping the decimation of the frame image.
According to a second aspect of the present invention, in the first aspect of the present invention, the control means performs the thinning-out control of the frame of the image so that the thinning-out rate decreases as the speed of the moving body increases.
According to a third aspect of the present invention, in the first or second aspect of the invention, when the speed of the moving body starts from a stopped state, the control means increases the thinning rate of the image frame until the first vehicle speed is reached. It is characterized by making it.
According to a fourth aspect of the present invention, in the first, second, or third aspect, the moving body is a car.

  According to the above configuration, in the process of raising the car from 0 km to the original speed or higher, the player can obtain a faster sensation speed and can play with a refreshing feeling as compared to the conventional case.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic view showing an appearance of a game machine according to the present invention, and shows an example of an automobile racing game machine.
An image display unit 7 is installed in front of the race game machine 1, and a handle 4 and a shift lever 5 are installed in front of the seat. Further, an accelerator pedal 6 and a brake pedal 8 are provided at the lower part. A coin insertion unit 2 is arranged in the race game machine 1. A total of four speakers 3 are installed on the left and right of the front part of the seat and on the left and right of the rear part.
During the game, as shown in FIG. 6, a map of a part of the course on which the player's car runs is displayed in the lower left corner of the race screen, a tachometer, a speedometer, etc. are displayed in the lower right corner, and the host vehicle travels on the back of the screen. An image is displayed.

  If you step on the accelerator, the speed of your vehicle will be accelerated, and the background picture will be a picture that flows behind.For example, if you hit a wall during a race and start again from a stopped state, Until the vehicle speed increases to a predetermined speed (for example, 100 km), the image that becomes the background screen is displayed after being greatly thinned out immediately after the start of the vehicle. When the speed exceeds a predetermined speed, the screen is displayed without thinning out the screen. When the vehicle is at or above a predetermined speed, the vehicle speed and the screen speed change in a one-to-one proportional relationship.

FIG. 2 is a block diagram showing an embodiment of the circuit of the game machine according to the present invention.
The coin insertion unit 2 is connected to the coin related device 13, the coin inserted into the coin related device 13 is accommodated, and the data is sent to the input / output control device 14. The operation unit 11 includes an accelerator pedal, a shift lever, a brake pedal, a handle, and the like, and these pieces of information are sent to the input / output control device 14. Further, there is a decision button and the operation information is sent to the input / output control device 14 in the same manner. The input / output control device 14 sends the received data to the CPU 12 via the bus 15. The ROM 18 stores a game machine control program, a race game program, and necessary data. Further, a vehicle speed versus image frame thinning rate table is stored. The RAM 19 is used as a work area when the CPU 12 performs calculation and processing. The RAM 19 also temporarily stores race history data (handle, accelerator, brake state, position, speed, etc. for each running frame) and data read from the HDD (line data table, course data, etc. for each course). To do.

In the sound processing unit 17, music signal output processing such as BGM is performed in accordance with an instruction from the CPU 12, and music or the like flows from the speaker during the demonstration or during the game.
The CPU 12 controls the entire game machine according to a control program read from the ROM 18 and executes a race game, a game control unit 12a, a vehicle speed detection unit 12b that detects the speed of the host vehicle, and an image according to the speed of the host vehicle. Each function of the thinning rate determination unit 12c that obtains a thinning rate of frames and determines the number of frames to be thinned is provided.

  The HDD 20 stores various courses such as course material data for generating courses A to N as game data. In addition, a line table is stored, and the line table is divided into steps at a certain distance (for example, every 1 m) for each course, and the speed to be driven is recorded for each step (position) of the whole course. It is a thing.

Next, with reference to FIG. 3, FIG. 4, and FIG. 5, a description will be given of processing of the game machine for making it possible to feel a sufficient vehicle sensation speed even when the host vehicle is in a low speed state.
FIG. 3 is a diagram showing the relationship between the speed of the car and the elapsed speed of the game machine. When the vehicle is at a predetermined speed or higher, for example, 100 km or higher, the elapsed speed of the game machine is the same as the actual time elapsed, and at 100 km or lower, the slower the speed of the host vehicle is, the higher the elapsed speed of the game is. Specifically, if the speed of the own vehicle is 100 km or more, the one second that the game elapses is the same as the actual one second. However, the slower the own vehicle speed, the longer the game elapses. In order to control the screen display so as to be shorter than the actual one second, the background screen frame per second is thinned out.

FIG. 4 is a graph showing the degree of the vehicle sensation speed that the player feels in the game with respect to the speed of the own vehicle when processed in this way. The lower the speed of the vehicle, the higher the sensation speed that the player can experience at the speed of the vehicle.
It should be noted that until the speed of the host vehicle reaches the first speed, the ratio of the sensible speed that is applied to the sensible speed that the normal player feels at the vehicle speed is increased. When the first speed is reached, the ratio b / a of the sensible speed that is normally applied to the sensible speed that is normally felt at that speed is maximized, and the ratio of the sensible speed that is applied from the first speed to the predetermined speed is It becomes small, and when it exceeds a predetermined speed, it becomes a sensation speed normally felt at that speed.

FIG. 5 is a diagram for explaining a specific example of the vehicle sensation speed in the game, the ratio of frames to be thinned out, and the elapsed speed of the game time with respect to the vehicle speed.
The upper and middle tiers in Table 1 are the perceived speed of the car in the game when the speed of the car reaches 0, 20, 40 ... 140 km. The sensation speed felt by the player is 35 km, and the sensation speed increased by 15 km (75% increase) is added to the sensation speed usually felt by the player. In addition, the sensation speed is 60 km with respect to the speed of 40 km of the own vehicle, and the sensation speed of 20 km (50% increase) is added to the sensation speed normally felt by the player. The sensation speed is 72 km with respect to the speed of 60 km of the own vehicle, and an sensation speed of 12 km (20% increase) is added to the sensation speed normally felt by the player. The sensation speed is 88 km with respect to the speed of 80 km of the own vehicle, and an sensation speed of 8 km (10% increase) is added to the sensation speed normally felt by the player. The perceived speed is 100 km for the speed of the host vehicle, and the speed of the subject vehicle is the same as the perceived speed of the player, and the faster perceived speed of the subject vehicle feels the perceived speed corresponding to that speed. It has become.

The upper and lower parts of Table 1 show the ratio of thinning out the frames of the image to be displayed when the vehicle speed reaches 0, 20, 40 ... 140 km in order to make you feel the sensation speed like the middle part. In addition, the ratio of thinning out 43%, 33.3%, 16.7%, 9.1%, 0%, 0%, and 0% frames for each speed of the own vehicle is shown. The speed is rapidly increased to 43% up to the first speed, but the rate of thinning out is gradually reduced until a predetermined speed thereafter. Above the predetermined speed, the frame of the image is not thinned, and the actual time and the elapsed time of the game are the same.
When attention is paid from the first speed to the predetermined speed in the graph 1, the elapsed speed of the game becomes smaller in proportion to the thinning rate of the image, and the increase in the sensation speed is gradually decreased. It is in the state.

The flow of processing by the game machine as described above will be described with reference to FIGS.
The following explanation is processing until the game actually proceeds, the car stops for some reason, starts running again, and reaches a predetermined speed or more.
When the accelerator pedal is depressed and the acceleration signal is received via the input / output control device 14, the game control unit 12a starts the host vehicle 29 displayed in FIG. 6 corresponding to the depression speed of the accelerator pedal. At this time, the game control unit 12a, the vehicle speed detection unit 12b, and the thinning rate determination unit 12c operate as follows. The vehicle speed detector 12b detects the speed of the vehicle running on the screen. In the vehicle speed detection method, the acceleration is calculated from the amount of depression of the accelerator pedal at the current vehicle speed, and the acceleration is added to the current vehicle speed.

The thinning rate determination unit 12c obtains the ratio of the frame of the thinned image from the table that has already been read out to the RAM 19 with respect to the obtained vehicle speed. The game control unit 12a actually thins out the frames based on the obtained thinning rate, and calculates an image frame to be displayed on the image display unit 7. For example, if the rate of thinning is 43%, in a game machine that displays 60 frames per second, the number of frames to be thinned is 24 frames, and every other frame and every other frame, 24 frames are thinned equally. The remaining 36 frames to be displayed are determined.
The game control unit 12 a instructs the image processing unit 16 to display the 36 frames, and the image processing unit 16 performs processing according to the instruction to display the image on the image display unit 7.
In this way, by referring to the table, the ratio of frames to be thinned while detecting the vehicle speed is displayed on the image display unit reflecting the frame thinning of the image.

As described above, even when the vehicle speed is low, the player can feel the speed of experiencing the car in the game, and can obtain a more exhilarating feeling than before. Note that since the elapsed time of the game is changed, the system will not fail even when performing a time attack or the like.
In this embodiment, the vehicle speed-image frame decimation rate table shows the image frame decimation rate at 20 km intervals. However, the vehicle speed can be changed continuously to obtain the decimation rate. A vehicle speed-image frame thinning rate table is prepared in advance, but it is also possible for the CPU to obtain such a table.
Moreover, although the example of the car race game machine was demonstrated as a moving body, a moving body can be applied also to other vehicles, such as a motor boat and an airplane, and can acquire the same effect.

  This is a racing game machine installed at game centers and event venues.
