Description

How to play tennis using a mobile terminal {A TENNIS GAME METHOD USING A MOBILE EQUIPMENT}

This document relates to a mobile game method using a mobile terminal, and more particularly, to a tennis game method using a mobile terminal.

In addition to the mobile terminal, there is provided a technology basis for playing games by executing game programs in various types of terminals. These technologies include a technology for receiving and executing game programs based on a wired or wireless network, as well as a technology for receiving and storing game programs in a file format based on a wired or wireless network, and a storage medium such as an optical recording device. A wide variety of techniques are provided, ranging from the technology of executing the listed game programs.

1 illustrates a game input key configuration implemented in a general game-only console. As shown in FIG. 1, a game input key implemented in a general game-only console includes a stick unit 10 for determining a cursor direction movement and one or more button units 11 and 12 for setting and option functions. In such a game-only console, the input of the stick unit 10 and the button units 11 and 12 can be recognized at the same time, thereby facilitating the progress of the game. For example, in the case of a tennis game, while the user moves the character to the stick portion 10, while setting the hitting position with the button portion 11 and moving the cursor to determine the position where the ball falls back to the stick portion 10 again. At the same time, by setting the drop position with the button unit 11, the game user can enjoy a tennis game. In addition, it is also possible to simultaneously input the striking strength value to the other button unit 12 according to the characteristic that can be simultaneously key input.

However, in the case of a mobile terminal, there is a problem in that the game method used in the general game console described above cannot be applied because there is a hardware limitation in that key input is impossible at the same time. In addition, in the case of a mobile terminal, hardware performance is lower than that of a high-end device such as a personal computer, and software or logic related to sound output is also low. The game needs to be organized.

In the above-described background technology, a tennis game method that can be enjoyed even in a mobile terminal environment in which hardware keys are not possible at the same time, and a computer readable recording medium recorded as an executable program are provided.

Tennis game method using a mobile terminal as a means for solving the above-described problems, the step of receiving a hitting position setting input from the game user through the setting key for the position aimed through the character movement in the user's character court, When the set hitting position is included in the hitting position reference range, displaying a cursor in the opponent character court, receiving the falling position aiming input of the ball from the game user through the cursor movement and the character on the game screen And striking the ball at the striking position and causing the ball to parabolically move to a drop position determined by the cursor position at the point of striking.

In addition, the computer-readable recording medium as a means for solving the above-mentioned problems, the step of receiving a hitting position setting input from the game user through the setting key for the position aimed through the character movement in the user's character court, When the set hitting position is included in the hitting position reference range, displaying a cursor in the opponent character court, receiving the falling position aiming input of the ball from the game user through the cursor movement and the character on the game screen A tennis game method using a mobile terminal is recorded as an executable program, which includes hitting the ball at the hitting position and displaying the ball in a falling position determined by the cursor position at the hitting point.

In the above two means, the time Δt between the hitting position setting input and the dropping position determining time may determine the hitting strength for the ball.

The hitting position and the dropping position may be aimed at a touch input on a screen of a mobile terminal where a direction key input of a mobile terminal or a touch screen is implemented.

In addition, when the hitting position is set in the first range (0 ~ A) of the hitting position reference, a general hit is made, and when set in the second range (A ~ B), the character position of the game user is corrected After the hit is made, the sliding hit may be made when the third range (B ~ C) is set (0 <A <B <C).

In addition, the parabolic motion is expressed through the equation of motion defining the position of the ball by substituting the elapsed time, the elapsed time may be determined differently from the frame elapsed time.

Outputs the dialogue while the game is in progress, using a dialogue table composed of corresponding dialogue contents for each identification number, and the identification number may include character information, situation information, and dialogue information.

Based on the time information of the mobile terminal, an image of a game screen or a dialogue content between characters may be changed.

According to the present invention, even in a mobile environment where a plurality of key inputs are impossible at the same time, the cursor is output to the counterpart code by setting the hitting position and the function of the direction key is switched to determine the hitting position as well as the dropping position.

In addition, there is an effect to provide a more lively game in consideration of the blow strength set based on the hitting position setting time.

In addition, even if the hitting position is not accurate, it is possible to increase the morale of the game user by applying a correction in a certain case, thereby having an effect that makes the game more enjoyable.

In addition, in expressing a parabolic projectile, that is, a ball movement, an elapsed time value is manipulated to be differentiated from a real time value without using complicated multidimensional equations, thereby displaying a natural and realistic effect.

In addition, it is possible to intrigue the game by outputting the appropriate dialogue for the game character or situation while the game is running, and the dialogue is managed by using the dialogue table defined by the identification number assigned to reduce the program execution load and add and modify the dialogue This has the effect of facilitating.

Also, by obtaining the time information of the mobile terminal and changing the game background screen or dialogue based on the time information, there is an effect of providing a more realistic game to the game user.

Hereinafter, with reference to the drawings will be described embodiments of a tennis game method that can be enjoyed in a mobile terminal environment with a hardware constraint that can not be simultaneously key input. However, specific contents for the implementation of the present invention described below are not limited to the tennis game, it will be obvious that it is applicable to a game of a similar manner such as a table tennis game or a badminton game.

2 is a flowchart illustrating a tennis game method using a mobile terminal according to an embodiment of the present invention, and FIGS. 3 and 4 illustrate capture screens during a game according to the tennis game method using a mobile terminal according to an embodiment of the present invention.

According to the present embodiment, during the tennis game using the mobile terminal, first, in step S20, the hitting position setting input is received from the game user through the setting key with respect to the position aimed by moving the character in the character court of the user.

According to the hitting position setting input according to the step S20 as shown in Figure 3a hitting position that the character of the user of the game user can hit the ball sent by the opponent character in the code range 31 on the game screen It may be displayed as moving to (A) and taking a striking posture.

At this time, the aiming position (A) can be made through the input of the direction key 32 of the mobile terminal. In this case, when simultaneous key input is impossible in the mobile terminal, a setting input is sequentially received through the setting key 33 after the aiming input is made through the direction key 32. Alternatively, the mobile terminal in which the touch screen is implemented may be made through a touch input on a screen of the mobile terminal. In this case, in particular, the hitting position setting input may be made simultaneously with the aiming input.

When the hitting position set in step S20 is included within the hittable position reference range, the cursor is displayed in the opponent character court in step S22, and the falling position aiming input of the ball is received from the game user by moving the cursor.

According to the drop position aiming input according to the step S22, as shown in FIG. 3B, the cursor 35 is displayed in the opponent character court on the game screen, and the cursor 35 determines the drop position at which the ball to be delivered after the hit falls. Moving within the code range 34 of the status room character may be indicated.

The aiming of the falling position (B) may be made through the input of the direction key 32 of the mobile terminal, similarly to the aiming of the striking position (A). That is, due to the input of the setting key 33 for determining the hitting position A, the function of the direction key 32 is changed from the movement of the character 30 for aiming the hitting position A to the movement of the cursor 35 for aiming the falling position A. Is switched. Alternatively, the mobile terminal in which the touch screen is implemented may be made through a touch input on a screen of the mobile terminal.

Then, in step S24, the ball hits the ball when the ball reaches the set position of the character of the user on the game screen. Then, the ball moves in a parabolic motion to the fall position in the opponent character court determined in step S22. At this time, the drop position may be determined by the cursor position at the point of time when the character of the user hits the ball.

According to the step S24 as shown in FIG. 3C, when the ball 36 reaches the hitting position A in which the character 30 of the game user is in the hitting position, the character of the Kaga user 30 is hit. The movement of the ball 36 to the cursor position, that is, the drop position B, at the time of hitting may be displayed according to the parabolic movement path 37.

In this embodiment, as described above, the setting of the hitting position A within the range where the game user can hit is directly connected to the hitting so that the cursor 35 is displayed in the opponent character court to receive the dropping position aiming input. Thereafter, even if there is no additional key input for the hitting, the hitting position setting is performed immediately by hitting.

At this time, in step S24, the character of the user of the game can determine up to the strength to hit the ball. For example, it is possible to set such that the blow strength for the ball is determined according to the time Δt between the hitting position determination in step S20 and the dropping position determination in step S22. If the drop position is determined at the time of hitting, it may be explained that the hit strength is determined according to the time that the user's character takes the hitting posture. According to this embodiment, the faster the impact position is determined, the greater the impact strength is determined, which may further increase the fun of the game user.

According to the determination of the blow strength according to the step S24 as shown in Figure 4 on the game screen, the size of the blow around the character 30 of the game user is determined according to the blow strength to indicate the blow strength (40) ) May be further included. The impact strength display 40 may be represented in various shapes such as flame shape or aurora shape.

According to this embodiment, the game user can determine the ball falling position by moving the cursor displayed in the opponent character coat after setting the hitting position, and hitting the ball at the time interval from the hitting position determination to the dropping position determination. By determining the blow strength, it is possible to keep the game fun at the same level as possible when the key input is possible by considering the hit strength as well as the drop position even when simultaneous key input is difficult.

5 illustrates a capture screen in which a hitting position of a user character is corrected during a game according to a tennis game method using a mobile terminal according to another embodiment of the present invention.

Meanwhile, when the game user sets the hitting position, whether or not the hitting position is determined according to whether or not the hitting position is determined in a dichotomy is possible. However, if the hitting only to set the hitting position accurately in the hitting position can increase the difficulty of the game can decrease the interest of the game user.

Therefore, in the present embodiment, a predetermined range is set on the basis of the hittable position, and in a certain case according to the hitting position set within the range, correction is made so that hitting is possible.

For example, when the hitting position is set in the first range (0 to A) of the hittable position reference, a general hit is made, but is in the second range (A to B) outside the first range (0 to A). If set, the character position of the game user can be corrected and hit according to the position correction. In addition, the third range B to C, which is also outside the second range A to B, may also be set and the sliding hit may be made when the second range is set (0 <A <B <C).

According to the present embodiment, as shown in the first capture screen of FIG. 5, if the character's hitting position 50 is not set exactly at the hittable position 51 on the game screen, if it is set within a predetermined range 52, the second capture As shown on the screen, the position of the character is corrected to the hitting position 51. When correcting the hitting position of the character according to the present embodiment, as shown on the second capture screen, the facial expression change 53 of the character may be further displayed. Then, as shown in the third capture screen can be displayed to take the striking posture at the striking position moved the strikable position 51 according to the correction.

According to the present embodiment, in the case of the effect of correcting the hitting position by not setting the hitting position at the hittable position correctly, it may be possible to apply a penalty for position correction such as reducing the hitting strength or reducing the force. In addition, the size of each of the above-described ranges can be adjusted according to the difficulty, and the range based on the hittable position may be set not only in two or three but more variously.

6 is a view for explaining a method of more realistically representing the parabolic motion of the ball on the game screen in the tennis game method using a mobile terminal according to another embodiment of the present invention.

According to this embodiment, when the parabolic motion of a ball is represented by varying the ball's position in multiple frames, the ball's position in each frame is determined by substituting the elapsed time into the equation of motion considering only the gravity applied to the ball. However, at this time, the elapsed time to be substituted is determined to increase inconsistently for at least some frames.

The ball according to the present embodiment is a projectile which is a flying object under gravity and drag. In general, projectiles are limited to objects that are initially driven by some force, such as shells, and then fly away without further propulsion. That is, in the case of a tennis game, when a tennis ball is hit with a racket, the tennis ball becomes a projectile and falls to an arbitrary position on the opposing court.

In order to describe the motion of this projectile, gravity and drag should be considered. To implement this program, numerical analysis considering gravity and drag should be used. In order to calculate the equation of motion, we need to use natural logarithm and square root or exponential. In WiPI or mobile environment, this kind of calculation requires much execution and it can be a burden to express the movement of the ball. It can also cause game disruptions.

Therefore, in the present embodiment, in order to describe the motion equation of the projectile as if it is drag in the mobile environment, the natural motion of the projectile is expressed by using a little execution as a method of adjusting the elapsed time in the program without applying complicated exponential calculation. Do it.

In other words, in a program, the elapsed time is generally entered and executed as a fixed value, which corresponds to the actual time felt by the actual user. For example, this value could be 50ms as the output time per frame. However, when calculating the projectile, that is, the equation of motion of the ball, use a simple two-dimensional equation of motion equation without drag as shown in Equation 1 and Equation 2 below. For example, by adjusting the elapsed time (t) without using a fixed value of 50ms, the projectile's time is expressed relatively faster than the actual time.

Equation 1 is a motion equation that can determine the horizontal movement distance of the ball. In Equation 1, x ₀ is the horizontal starting position of the ball, v is the starting speed of the ball, θ is the launch angle of the ball, and t is Indicates elapsed time.

Equation 2 is a motion equation that can determine the vertical movement distance of the ball. In Equation 2, y ₀ is the vertical starting position of the ball, v is the starting speed of the ball, θ is the launch angle of the ball, and g is Gravitational acceleration and t represent elapsed time.

In Equations 1 and 2, t represents the total elapsed time. Since the program is executed on a frame basis, the displacement is calculated by adding the elapsed time of the frame to the total elapsed time. Thus, by manipulating the elapsed time value for each of these frames, the parabolic motion of the projectile can be expressed as if drag is applied. Table 1 below shows an example of separately manipulating the elapsed time value for each frame of the projectile, that is, the ball.

frame Elapsed time Actual time Elapsed time of projectile Projectile time One 0.05 0.05 0.1 0.1 2 0.05 0.1 0.095 0.195 3 0.05 0.15 0.09 0.285 4 0.05 0.2 0.085 0.37 5 0.05 0.25 0.08 0.45 6 0.05 0.3 0.075 0.525 7 0.05 0.35 0.07 0.595 8 0.05 0.4 0.065 0.66 9 0.05 0.45 0.06 0.72 10 0.05 0.5 0.055 0.775 11 0.05 0.55 0.05 0.825 12 0.05 0.6 0.05 0.875 13 0.05 0.65 0.05 0.925 14 0.05 0.7 0.05 0.975 15 0.05 0.75 0.05 1.025 16 0.05 0.8 0.05 1.075 17 0.05 0.85 0.05 1.125 18 0.05 0.9 0.05 1.175 19 0.05 0.95 0.05 1.225 20 0.05 One 0.05 1.275

As you can see in Table 1, when the actual time the game user sees through the screen is 0.5 seconds (10 frames), the projectile will go up faster and fall after 0.775 seconds.

In FIG. 6, the parabolic motion displayed on the left side shows the motion of the ball for the case where the elapsed time of the ball is applied in the same way as the actual time, and the right side shows the ball for the case in which the elapsed time of the ball is manipulated and applied according to the present embodiment. The movement is shown. In particular, according to Table 1, by setting the elapsed time for the initial frame larger than the actual time, the parabolic motion considering not only gravity but also drag can be expressed.

However, when drag is applied, as the total time of reaching the target point by drag decreases, the final x, y displacement C decreases as the elapsed time per frame is manipulated as shown in the right side of FIG. 6. However, this part can be expressed as moving from the set hitting position (A) to the dropping position (B) by solving by multiplying the appropriate constant by the initial speed.

According to the present embodiment, even if the parabolic movement of the ball is expressed by a simple motion equation that only considers gravity, it can produce an effect similar to considering various external forces, such as drag, by manipulating the elapsed time per frame. While reducing the load, it has the effect of displaying more realistic and natural ball movements to game users.

On the other hand, in a tennis game using a mobile terminal, if the appropriate dialogue is displayed according to the personality or situation set for each character during the game, the user can feel like playing the game while having a conversation with the actual opponent in the game to increase the fun of the game. Can be. As such, in order to display the dialogue of characters, a method of storing and managing scripts in the form of document files for each character and each situation is used. Below is a dialogue file that displays after a serve during Character 1's game.

-------------------------------------------------- --------

GAME_DIALOG SERVICE

{(Message, expression, dialogue)

msg 0 "Ughhahahaha"

msg 1 "Ughhahahaha"

(0: anger, 1: joy)}

-------------------------------------------------- ---------

According to this, when the character 1 succeeds in the game, the "uhhahahahah" is displayed with an angry expression or with a happy expression. However, if the script is managed in the form of a document file in this way, there is a problem that the document must be set and managed separately for each character and each character situation.

FIG. 7 is a diagram for describing a method of managing metabolism in a game using a metabolism table in a tennis game method using a mobile terminal according to another embodiment of the present invention.

In this embodiment, the dialogue is output while the game is in progress, and a dialogue table composed of corresponding dialogue contents for each identification number shown in FIG. 7 is used. The identification number is composed of character information, situation information, and metabolic information. Table 2 below shows an example of the metabolic table constructed according to the present embodiment.

ID expression script 1000000 -One Are you not throwing the ball? 1000001 -One Uh huh? 1000002 0 Baruck !! Quickly!! 1000003 -One Are you ... 1000004 4 I was scared. 1000100 -One It's so exciting ~ 1000101 -One Try it well ~ 1000102 -One Bravo ~! 1000103 0 Can you see me? 1000104 4 I'm stuck.

As can be seen from Table 2, it can be seen that the metabolism table has a plurality of metabolic contents each having an identification number assigned thereto. In this case, facial expression information may be additionally defined. That is, using the metabolic table according to the present embodiment, it is possible to easily access and output the corresponding metabolic contents through the identification number. In addition, in order to increase accessibility, the identification number is preferably assigned in consideration of the character and the situation, which are the criteria for defining metabolism. Table 3 below shows an example of an identification number configuration method.

One 0 0 0 0 0 0 Characters situation script

As can be seen from Table 3, the identification number can be configured to consist of information identifying the character, information identifying the situation and information identifying the dialogue. For example, when the character information is 00, 01, 02, each represents a character chapter, a spring, a Laura, and when the situation information is 00, 01, each represents a sub delay and a service ace. And, if the metabolic information is one of 00 ~ 04 can be displayed arbitrarily selected from the five metabolism. In addition, as shown in Table 3, even if the character is 00 can be configured to further include a number of '1' to fit the digits.

For example, suppose that the character's confrontation structure is chapter vs. Laura and the Laura character is in a sub-deferred situation. As an chapter character, an appropriate one of the lines assigned to each identification number from 1000000 to 1000004 with an identification number starting with 10000 Ambassador, for example, the identification number 1000001, 'Huh .. won't you?' Will print. Then, when the server of the Lora character is successfully performed, the Lora character also has one of the appropriate lines of the ambassadors assigned to each of the identification numbers 1010100 to 1020104 whose identification numbers start with 10201, for example, the identification number 1020101. Will print it out.

Using the dialogue table and identification number defined in Table 2 and Table 3 to output the dialogue appropriate to the character and the situation, it is possible to collectively manage one table by changing only the identification number for each character, thus reducing resource capacity. The benefits of this approach are, of course, much more convenient than traditional methods in terms of management and modification. In addition, even if a character, a situation or a dialogue is added, it may be easily added by simply adding an identification number in the dialogue table and corresponding dialogue contents without adding a file.
