Description

An on-line game server

The present invention relates to a video game, and more particularly, to a method and apparatus for extracting a BPM from a music file selected by a user and adjusting a kind and an appearance frequency of an obstacle in accordance with the extracted BPM so that a user can play an exciting game And an online game server for providing a video game to a plurality of clients via a network.

A variety of games have been developed and spread thanks to the development of electronics. Especially, various online game services are provided according to the development of the network. In addition, due to the improvement of the graphics technology and the performance of the game user terminals, high-performance game programs are being produced, and game contents in which a real world or a virtual world is precisely depicted are being provided. Furthermore, as smartphones have become widespread, there has been an environment in which a variety of games can be enjoyed at anytime and anywhere by using a phone that is always in possession rather than a dedicated game machine.

There are various genres of games that you can enjoy using your smartphone or client. A popular game in the early game model is an arcade game, including brick-breaking games and Tetris. In addition, there are shooting games where users have to hit buttons, and games such as Gallus, Zebius, Airplane, and 1942 are included. Furthermore, it is possible to create a simulation game in which virtual reality is created in a virtual world, a puzzle game, a scenario, an adventure game in which an adventure is carried out through an adventure game, a board game such as a chess or a long term, There is a role playing game which is a game to level up with defeating enemy with. In the early stage of the game development, arcade games, puzzle games, and board games were popular, but adventure games and role-playing games are attracting much attention as the game industry develops.

Among these kinds of games, arcade games are so popular that they are all game aids, and they have the advantage of being easily accessible and enjoyable. Arcade is a term used to refer to a roof-topped shopping district. It is derived from the fact that the arcade was mainly located in arcades in North America. Particularly, there is nothing arcade games that can be enjoyed using the empty time slots in a short time, which applies to smartphone users as well.

In addition to the strategy and story of the game itself, the elements that interest the game include graphical environmental factors and sound related factors. As graphics processors evolve, more sophisticated graphics processing becomes possible, and users are more immersed in the game with rich graphics performance similar to the real world. In addition, the sound environment is also very important. The sound used in the game plays an important role in increasing the tension of the game by simply moving away from the background music, notifying the progress of the game, and enhancing the user's immersion.

Korean Patent Application No. 10-2006-7000545 "Timing Offset Permissible Karaoke Game" discloses a technique for correcting a wrong timing of singing in a karaoke game, which is a type of typical music game. According to the prior art, if the score generated by the user is within an allowable amount (e.g., pitch amount) of the corresponding target score, it is operable to detect that the user has successfully performed the target action. Thus, music plays a role as a main component of the game, out of its role as the background of the game.

However, according to the related art, the user is forced to play while listening to the music registered by the game creator. Generally, a game maker uses music that is most suitable for a game designed by him or her by arranging conventional music, or composes and inserts music dedicated to the game. Of course, such music is carefully prepared to increase game immersion, but as a result, when the user enjoys the same game, the result is that only the predetermined game music is repeatedly heard at first.

Therefore, there is a desperate need for a technology capable of increasing the user's degree of immersion by not only deciding the music of the game by the user, but also configuring the progress of the game and the music determined by the user in harmony with each other.

In order to fully understand the present invention, operational advantages of the present invention, and objects achieved by the practice of the present invention, reference should be made to the accompanying drawings and the accompanying drawings which illustrate preferred embodiments of the present invention.

Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. However, the present invention can be implemented in various different forms, and is not limited to the embodiments described. In order to clearly describe the present invention, parts that are not related to the description are omitted, and the same reference numerals in the drawings denote the same members.

1 is a block diagram schematically showing a video game apparatus according to an aspect of the present invention.

1, a video game apparatus 100 according to the present invention includes an interface 110, a silence processing unit 120, a bit determination unit 130, an obstacle attribute determination unit 140, a game progress processing unit 150, A result processing unit 180 and a database 190. [

The interface 110 receives the user's input, and provides the user with the progress of the game, the game result, and the like. That is, the interface 110 can operate as an input / output device.

When the interface 110 receives the music selected by the user, the silence processing unit 120 selects and processes a portion of the received music that is not suitable for the game. That is, when there is a silent period in the loaded audio file, the silence processing unit 120 determines the game music to be inserted into the silence period, and inserts the determined game music into the silence period. In the present specification, the silence period may indicate not only the silence period present in one song, but also the time until reproduction of one song ends and reproduction of another song starts. Further, the silence period does not necessarily indicate a section in which the music is not reproduced, and may indicate a section in which the volume of music is below a predetermined value, that is, a section of music which is not suitable for use as a background music of a game. For example, an interval that is too slow for the music to be suitable for the game may be included in the silence.

Since other music suitable for the silence period is selectively inserted by the silence processing unit 120, portions not suitable for the game are excluded in the music used for the game. Therefore, the user can immerse in the game while maintaining a certain level of difficulty as a whole. The music that can be inserted into the silence period may be stored in advance in the database 190, or may be inserted into a voice memo for notifying that it is silent and urging the next step. Alternatively, a voice message indicating the score up to the present time and urging the recovery can be inserted into the silencer.

The bit determination unit 130 analyzes the loaded audio file to determine the bit of the audio file. All music is made on the basis of time scales such as bars or beats. When playing an audio file, the beat serves as a timing to play the note. As described above, since the music is defined as a measure or a beat, the performer can flexibly cope with fluctuations in the tempo and rhythm, and it is possible to give personality to each player in tempo and rhythm even in the performance of the same score.

In this manner, the music selected by the user is mixed down in the form of a performance of each musical instrument, for example, two channels of stereo, and is provided as one complete package. do. Such a completed package is delivered to the user as a sound source using, for example, a PCM (Pulse Code Modulation) method. Therefore, such a sound source includes information on timing such as a measure or a beat. Therefore, in order to extract the bit information included in the reproduced audio file, a bit extraction technique should be used.

There are two types of bit extraction: extraction in the time domain and extraction in the frequency domain.

FIG. 2 illustrates a bit determination unit 130 for extracting bits in the dual time domain. 2 includes an average value calculation module 210, an absolute value calculation module 230, a comparison module 250, and a recording module 270. The average value calculation module 210, the absolute value calculation module 230,

The average value calculation module 210 analyzes the waveform of the audio file in the time domain, and calculates an average value for every one second interval, for example. Then, the absolute value calculation module 230 calculates the absolute value of the waveform amplitude for every interval shorter than one second, for example, for 0.05 second intervals. Thus, the bit determination unit 130 shown in FIG. 2 extracts the bits directly through the amplitude of the waveform in the time domain. In this process, an interval having an absolute value higher than the average value for a predetermined time interval (for example, 1 second) may be determined to be an interval including a bit.

Also, the average value calculation module 210 may exclude a waveform whose amplitude is below a certain value, when calculating the average value. The reason for this is that it is necessary to have a relatively strong beat tone in order to construct a beat, as it is difficult to detect such a beat tone when the volume of the audio file as a whole is low. When the average value calculation module 210 deletes waveforms with a small volume and calculates an average value, the risk that the average value is lowered due to a small volume and the bits are misjudged more than necessary can be reduced.

If an average value of a certain time interval (for example, 1 second) is determined, the absolute value calculation module 230 divides the corresponding interval into a plurality of sub-intervals. Then, the comparison module 250 detects a bit according to whether or not a waveform having an amplitude larger than an average value among the absolute values of the respective sections exists. When the bit is detected, the recording module 270 records the time at which the bit was generated.

To explain the bit extraction process in the time domain, refer to Fig. 4 (a). FIG. 4 is a diagram illustrating a process of determining bits in the bit determination unit 130 shown in FIG. 2 and FIG. 3. Referring to FIG. 4 (a) shows an example of a time waveform of a digital audio signal. In the time waveform shown in FIG. 4 (a), it can be seen that there is a portion that makes a large peak value in some places. The portion constituting the large peak value is, for example, a portion corresponding to a part of the bits of the drum, which is detected by the comparison module 250.

Thus, the bit determination unit 130 shown in FIG. 2 determines a bit in the time domain. However, there are cases where it is difficult to extract the bits in the time domain in a case where there are many musical instruments to be used, a lot of noise, and the like. Therefore, there is a need to extract bits in the frequency domain as in Fig. For example, in the time waveform of the digital audio signal having the time waveform shown in Fig. 4 (a), it may be hidden, but if the music of the digital audio signal having the time waveform shown in Fig. 4 (a) , It can be seen that more bit components are included at substantially equal intervals. That is, it may be difficult to extract the bit component of the rhythm of music only with the peak value of the time waveform shown in Fig. 4 (a).

As used herein, the term " module " refers to a particular function, for example, software, hardware, or a combination of hardware and software. In particular, a module may be a component, such as a software component, an object-oriented software component, a class component, and a task component, and may be a process, a function, an attribute, a procedure, a subroutine, a segment of program code, , Circuits, data, databases, data structures, tables, arrays, and variables. The functions provided in the components and modules may be combined into a smaller number of components and modules or further separated into additional components and modules.

3 is a block diagram showing another embodiment of the bit determination unit 130 included in the video game apparatus shown in FIG.

3 includes a spectrum calculation module 310, a rate of change calculation module 330, a comparison module 350, and a recording module 370.

The spectrum calculation module 310 receives a digital audio signal having a time waveform as shown in Fig. 4 (a). Then, the spectrum calculation module 310 can not extract the bit component with high accuracy from the time waveform. Therefore, the spectrum calculation module 310 can calculate the time waveform using the FFT (Fast Fourier Transform), for example, The same spectrum is produced. When the sampling frequency of the digital audio signal is 48 kHz, it is preferable that the resolution in the FFT calculation is set to 5 to 30 msec in real time with the number of samples being 512 samples or 1024 samples. The various numerical values are not limited to these. In addition, it is generally preferable to perform FFT operations while overlapping windows while applying a window function (window function) such as hanning or humming. Once the spectrum is calculated, the spectrum calculation module 310 supplies the result to the rate of change calculation module 330.

The change rate calculation module 330 calculates the rate of change of the power spectrum supplied from the spectrum calculation module 310. [ That is, the rate of change calculation module 330 calculates the rate of change of the power spectrum by performing a differential calculation on the power spectrum supplied from the spectrum calculation module 310. The change rate calculation module 330 repeatedly performs differential calculations on the power spectrum changing at various angles and supplies the result to the comparison module 350. [ At this time, it is preferable to remove the chattering of the signal by adding a hysteresis characteristic based on the time constant appropriate to the change rate calculation result in order to increase the robustness of the signal transmitted to the comparison module.

When the rate of change is calculated, the result is provided to the comparison module 350. At this time, among the bit extraction waveforms shown in (c) of FIG. 5, the peak rising in the forward direction is regarded as a bit component.

The comparison module 350 sets a proper threshold value and detects a bit after suppressing low level noise from the rate of change received from the rate of change calculation module 330. [ To this end, the comparison module 350 extracts only a rate of change having a level equal to or higher than a threshold value among the rate of change received from the rate of change calculation module 330, and transmits the extracted rate to the recording module 370 as bit information. Then, the recording module 370 records bit position information indicating the time position of the bit component.

In this way, the bit determination unit 130 shown in FIG. 3 extracts bit position information from the frequency spectrum of the digital audio signal, and the operation of each component can be controlled by changing internal parameters. Of course, the internal parameters can be optimized automatically or can be adjusted manually by the user.

5 is a block diagram illustrating an embodiment of an obstacle attribute determination unit 140 included in the video game apparatus shown in FIG.

The term " obstacle " as used herein means a target to be overcome or a task to be accomplished in the progress of the game. Thus, the obstacle may be a target of defeat appearing in a breaking game, or an enemy character appearing in a fighting game. All items included in the game can be obstacles, such as a slip hazard area, a tire puncture hazard area, or an attacking weapon that the driver of the opponent driver attacks on the opponent driver or course that competes in a racing game.

According to the present invention, the obstacle is not determined at the time of game design but is designed differently according to a bit of music to be selected by the user. The attributes of the obstacle determined according to the beat of the music may include the type of the obstacle, the number of the obstacles appearing, the location of the obstacles, the combination of the obstacles continuously appearing, and the appearance frequency of the obstacles. If the obstacle is an item that the user needs to acquire or a mission to accomplish, the obstacle attribute may include the type of item, the number of appearances, the effect of the item, and the difficulty of the mission.

Referring to FIG. 5, the obstacle attribute determination unit 540 includes a BPM determination module 510, a difficulty determination module 530, and an obstacle policy determination module 550.

The BPM determination module 510 determines the BPM of the audio file from the bits determined in the bit determination unit 130 in FIG. BPM means the number of bits per minute, and the average BPM can be calculated by the following Equation (1).

[Equation 1]

Average BPM [bpm] = sampling frequency / average bit period × 60

The average bit period in Equation (1) can be calculated as Equation (2).

&Quot; (2) "

Average bit period = (last bit position - first bit position) / (total bit number - 1)

Using Equations (1) and (2), the BPM determination module 510 can obtain an average BPM.

When the BPM is determined, the difficulty level determination module 530 determines the total number and types of obstacles to be appeared in consideration of the difficulty of the video game. The reason why the obstacle policy is determined in consideration of the difficulty level in the BPM determination module 510 is that the game must be configured differently according to the degree of difficulty of the game even if the game is composed using the same music. For example, using the same music may cause obstacles to appear twice as often at difficulty levels than at low levels.

When the degree of difficulty is determined in this way, the obstacle policy determination module 550 determines an obstacle policy including an appearance position of the obstacle. That is, when the obstacle policy is determined, an obstacle occurs at a position according to the determined obstacle policy, and the obstacle is processed by the game progress processing unit (150 in FIG. 1) so that the obstacle appears at the time when the bit is generated.

6 is a block diagram showing an embodiment of the game progress processing unit 150 shown in FIG.

6 includes a CPU 610, a system controller 620, a GPU 630, a monitor 640, a video signal processing unit 650, a user input receiving unit 660, an SPU 670 ), And a database 680. Each component exchanges data via the system bus.

The CPU 610 controls the overall operation of the video game apparatus in accordance with the user input signal transmitted from the user input receiving unit 660. Basically, the CPU 610 operates based on an operating system (OS) stored in the database 680 to establish a basic platform environment of the video game apparatus, manages game save data based on the established platform environment, .

In particular, the CPU 610 manages generation / update / deletion of one or more game save data generated by a user executing a specific game. In addition, when the user's game execution request is inputted through the user input receiving unit 660, the CPU 610 checks whether one or more pre-stored game save data exists, and if there is one or more stored game save data, After the information on the save data is output to the user, the game save data selected by the user is converted according to the platform type and applied to the game.

To this end, the CPU 610 collects game state information changed at the end of the game and generates new game save data or updates the selected game save data.

The system controller 620 controls interrupt control, time control, memory control, and direct memory access (DMA) transmission. The database 680 temporarily stores the game program and data, and also stores various data related to the game.

The GPU 630 generates image data to be displayed on the monitor 640 in accordance with an instruction from the CPU 610. [ In other words, the GPU 630 reads the coordinate data, the movement amount data, and the rotation amount data of each vertex in the two-dimensional or three-dimensional plane of the image data supplied from the CPU 610, Not only the address but also the address data can be transmitted to the CPU 610 again. Further, the GPU 630 may calculate the brightness of the image according to the distance and angle from the set light source. Further, the GPU 630 draws the image data stored in the buffer in accordance with the drawing instruction from the CPU 610, and outputs it to the monitor 640 as a game screen. The monitor 640 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT), a light emitting diode (LED), an organic light emitting diode (OLED) Light emitting diodes (LEDs), flexible displays, and three-dimensional displays. The database 680 is a means for storing data or programs necessary for the operation of the game apparatus, An operating program (OS) executed by the CPU 610, and one or more application programs including a game program.

The video signal processing unit 650 is responsible for decoding the still image or moving image data compressed or encoded by MPEG or JPEG stored in the database 680. [ In order to facilitate image processing, the image signal processor 650 may include a separate independent cache.

The user input receiving unit 660 may include various input devices. For example, the user input receiving unit 660 may receive a user input signal from a key input unit, a touch input unit, a gesture input unit, a voice input unit, or the like. The key input means generates a signal corresponding to the key according to the key operation, and corresponds to a keypad and a keyboard. The touch input means is a touch pad, a touch screen, and a touch sensor for recognizing an input operation by sensing a user's operation of touching a specific portion. The gesture input means recognizes a specific operation, such as a shaking or moving operation of the terminal device, an approach to the terminal device, a blinking operation, etc., as a specific input signal, such as a geomagnetic sensor, A sensor, a camera, an altimeter, a gyro sensor, and a proximity sensor.

The sound processing unit (SPU) 670 generates a voice signal including a BGM, an effect sound, and a voice message according to an instruction from the CPU 610, and outputs the voice signal to the monitor 640 or the audio output device. Of course, the audio signal output by the SPU 670 may include not only the music selected by the user but also various sound effects and voice messages generated according to the operation of the game.

The database 680 may include an audio file loaded by the user, a BPM extracted from the audio file, a difficulty of the game, an obstacle policy determined according to the degree of difficulty, and a game scenario. In addition, the database 680 may include information related to the game and information such as game progress, game progress history, and game result. Furthermore, the database 680 can also function as a cache memory for temporarily storing various data for image processing of the GPU 630, video signal processing of the video signal processing unit 650, and audio processing of the SPU 670 have.

7 is a screen shot of a game implemented by a video game apparatus according to an aspect of the present invention.

The present invention can be applied to various video games and is not limited to the particular game illustrated. However, for convenience of explanation, a scenario of a video game to which the present invention can be applied will be described as follows.

Synopsis

In the Saga Kingdom there was a birthstone to keep it safe and peaceful, but the tortoise that stole the birthstone for 2,000 years stole it. The Leo Prince of Sog kingdom goes on an adventure to find the lost birthstone of the kingdom.

Goal of the game

To get rid of the obstacles and to survive for a long time

Viewpoints and views

Third person quarter view

Game manipulation and progress

It provides intuitive and simple operation so that anyone can easily play the game. The user manipulates a button corresponding to the position of the obstacle appearing on the screen, or executes a motion to directly defeat the obstacle.

Many of the obstacles that appear in light background music are immersed in the game while defeating the rhythm. Instead of destroying obstacles only with a simple touch, you can destroy certain obstacles by dragging. Therefore, it is possible to reduce the boredom coming from the game's 'repeatability' of the game.

Furthermore, it induces manipulation utilizing the characteristics of each obstacle. For example, in the case of a hammer, a bubble, or a balloon, a touch operation is performed. In the case of a barricade with a wheel, a soccer ball rolling, or the like, a drag operation is used. This presents an intuitive obstacle solution to the user.

The rhythmic progression through the background music makes the game more interesting.

Background music

The background music can be selected by the user. If the user does not select it, it will use fast tempo music as background music. In order to add more rhythm, the tempo of the music gradually increases as the combo phase goes up, creating an atmosphere to feel the imminent situation.

As a game sound effect, the appearance of the obstacle and the sound effects of the destruction are exaggerated and made to sound loudly. This increases players' immersion in the game.

Key Features

- Frustration: In the case of existing running games, the obstacles must be avoided or certain conditions must be met to pour the obstacles. Users can get thrill to avoid them, but they do not have the excitement to get rid of obstacles. The game used in the present invention can achieve both excitement and excitement by directly defeating obstacles.

- Achievement Reward: Adds additional rewards not only to the ranking systems that are common in existing games. It is the addition of icon changes through the 'achievement' compensation system. The achievements of high record and special icon acquisition are rewarded by the game, which makes the player feel superior by adding differentiation to better players and users who have played for a long time. For some stages, you need to have a "specific achievement," but you can put it on a stage that you can buy.

- Easy operation and simple interface: If you touch the left or right side of the obstacle, the obstacle will be destroyed immediately, so the user can enjoy the game easily with simple operation. If you use motion detection, you can destroy obstacles in corresponding positions by stretching your left hand or by lifting your left foot directly.

- Ranking function: I set up a higher record and put in a system that can naturally compete with other users. This ranking system encourages competition among users and naturally induces game play. With the ranking system, players who score higher than others will feel a sense of accomplishment and superiority.

- Gesture input function: Game users use 'gesture enabled', which is used as a pattern lock on the smartphone, to destroy obstacles. Such gestures may include not only the movement of the finger on the touch screen, but also movement of the user sensing by the motion detection sensor, or movement of the smartphone itself.

- Combo function: If the obstacles are defeated in succession without fail, the combo will accumulate and the amount of points will increase as the combo keeps for a long time. Build a lot of bonus points through the combo to keep the game intensive and immersive. When the combo function is applied, the sound effect is also enhanced, which can cause interest.

 - Rhythm and action: In the course of the game, the obstacle comes out according to the background music. You can touch the obstacle by touching or dragging to the rhythm of the background music. Therefore, simple and pleasant game presentation is possible through this.

Differentiation factor

A game to which the present invention can be applied is a new mixed genre that adds a rhythm action to a 3D runner game, and can have a form of action using two methods of drag and touch, rather than a game operated by a simple touch.

In addition, it is possible to create profitability by placing a banner at the bottom of the screen, which is not affected when the player playing the game, and the banner at the top.

Above all, the video game according to the present invention allows the user to directly select the background music, and the interest of the user is increased because the obstacle appears in accordance with the selected background music.

8 is a flowchart showing a video game control method according to another aspect of the present invention.

First, an audio file to be used for starting the game is loaded (S810). Then, as described above, the loaded audio file is analyzed to determine the bit of the audio file (S820). As described above, it is possible to extract bits in the time domain or the frequency domain to determine the bits of the audio file. If the bit is determined, the obstacle attribute is determined based on the determined bit (S830). The obstacle properties include the kind of the obstacles to appear in the video game, the appearance position, the appearance time, and the like. These obstacle attributes can be determined differently depending on the difficulty level of the video game. After determining the BPM of the audio file to determine the obstacle property, the obstacle policy can be determined in consideration of the degree of difficulty as described above. The obstacle policy includes the timing and location of obstacles to be used in the game. When the timing of an obstacle appears, the difficulty increases.

If the obstacle property is determined, an obstacle is displayed with reference to the obstacle property while the video game proceeds, and the video game is proceeded based on the interaction between the obstacle and the user (S840). At this time, the obstacle appears at a time determined according to the obstacle policy, and the character corresponding to the user is controlled in the video game according to the received user input. As described above, not only the dedicated controller but also the user's tapping, dragging, and motion sensing can be included as the user input.

These operations are continued until the game ends (S850). The termination of the game can be determined based on the passage of a predetermined playing time, the achievement of the predetermined number of times of punishment, the game stage clear, the forced termination by the user, and the termination of the loaded audio file.

When the game ends, the game result is output (S860).
