Description

TECHNICAL FIELD [0001] The present invention relates to a method and an apparatus for removing dead space in a fixed-point 3D game,

The present invention relates to game technology. More particularly, the present invention relates to a method for eliminating a dead space generated at the end of a map in a point-fixed 3D game.

Games for personal computers or home game console platforms are being developed in a variety of ways.

Among these games, there are various games ranging from a casual arcade game having a simple operation mode to an RPG (Role Playing Game) operated by moving the player character on a massive map.

On the other hand, games of the type that moves their player character on a large game map that is not displayed on one screen among them can not proceed any further to the end of the map.

1 is a diagram illustrating a state in which a player character moves on a game map.

1, a partial area of the map is displayed on the screen with the player character as the center. When the player character moves to the end of the map, there arises a problem of how to display the area outside the end of the map .

In this case, a first person shooter (FPS) game is often interrupted by features such as walls that are no longer allowed to proceed.

On the other hand, in the case of RPG, various features (trees, walls, sea, etc.) that can not be progressed are filled up on the screen and processed as something that can not proceed any further.

FIG. 2 is a screen of the online RPG game "Lineage " according to the related art, and the upper left corner of the screen corresponds to the end of the game map in which the player character can no longer move. In the upper left corner of the screen of Fig. 2, it can be seen that "sea"

In other words, when the player character moves to the end of the map, it indicates that the game can not proceed any more by displaying a meaningless feature on the screen. In this case, the features filled in the screen fill the screen, That is, it corresponds to a dead space.

In the third person game, which moves the player character on the game map, a dead space is generated at the end of the game map. Nevertheless, the adventure game can freely change the viewpoint of the camera, It is not a problem in a game of a type having a user interface capable of moving the player.

That is, even if the player moves to the end of the game map, various objects for game play are displayed instead of dead space filled in the screen by moving the player character to a specific position on the screen by clicking on the screen or adjusting the camera angle This is because the user can operate it as much as possible.

On the other hand, in an RPG having an action action such as "Aion" and "Blade & Soul" of the present applicant or a PVP (Player vs Player) game derived from the RPG, the player character is always positioned at the center of the screen .

That is, when the player character moves on the game map, the game map is scrolled and displayed on the screen, and the actual player character only performs the walking or running action in place.

However, when a third person game is played by manipulating the player character on the game map as described above, the screen is filled with a meaningless dead space instead of MoBile Object, NPC (Non Player Character), or player characters of other gamers There is no problem in the case of a classic RPG as shown in FIG. 2, but in the case of a recent action RPG, a problem arises that rapid judgment and manipulation become difficult.

Particularly, in the case of PVP, it is very disadvantageous in a state in which only the dead space is displayed on the screen so as to cope with and manipulate the player character appropriately while watching the action or state of the player character of the opponent player.

In other words, if you go to the end of the map at PVP, the dead space makes the situation quicker, so dead space is a big obstacle to game play.

Therefore, it is necessary to remove the dead space that occurs when the player character moves to the end of the game map in a third person game such as an action RPG.

In particular, in the case of a 3D game with a quater view in which the cognitive load is doubled as compared to the top view, the necessity of removing such a dead space becomes even greater.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the present invention and the accompanying drawings, wherein like reference numerals refer to like elements.

It is to be understood that when an element is referred to as being "comprising" another element in the description of the invention or in the claims, it is not to be construed as being limited to only that element, And the like.

Also, in the description of the invention or the claims, the components named as "means", "parts", "modules", "blocks" refer to units that process at least one function or operation, Each of which may be implemented by software or hardware, or a combination thereof.

FIG. 3 is a functional block diagram for explaining the configuration of a dead space removal apparatus in a point-fixed 3D game according to the present invention.

3, the dead space elimination apparatus 100 in the point-fixed 3D game according to the present invention includes an input processing unit 110 and a rendering processing unit 120. [

The dead space removal apparatus 100 in the point-fixed 3D game according to the present invention can be implemented in the form of an apparatus in which instructions for executing a game are executed.

That is, the dead space elimination device 100 in the point-fixed 3D game according to the present invention may be a form of hardware resources such as a personal computer, a smart phone or a tablet computer for executing game software, . ≪ / RTI >

Meanwhile, it may be implemented in the form of an online game server providing various data related to an online game, or in the form of software executed in conjunction with an online game server, so that a game client accessed through such a network can conduct an online game.

On the other hand, as mentioned above, the dead space removal apparatus 100 in the point-fixed 3D game executes a game having the following restrictions.

First, the dead space elimination device 100 in the point-fixed 3D game according to the present invention is intended to solve the dead space problem when the player character moves to the edge of the game map,

First, the game progresses by moving the player character in the game map. Preferably an action RPG.

On the other hand, there is no problem in the 2D game because the data processing method is simple, such as defining the scroll method with two objects of the map data and the screen. However, in the case of the 3D game, The graphics processing is performed in such a manner that it is rendered and displayed in real time, so that a problem of processing dead space arises.

Therefore, it is assumed that a 3D game in which three-dimensional objects viewed through a camera are rendered and displayed in real time.

The input processing means 110 constituting the apparatus 100 for removing dead space in the point-fixed 3D game according to the present invention receives an input relating to the movement of the player character from the user.

The user can manipulate his / her player character on the game map by using an input device such as a keyboard or a mouse.

The input processing means 110 receives such user input.

On the other hand, when the coordinates of the player character on the game character map are changed according to the input of the user, the rendering processing unit 120 renders various objects on the game map and map displayed on the camera with the changed coordinates and displays them on the screen.

At this time, coordinate the camera with the player character.

Linking the coordinates of the camera means setting the camera in a certain position and direction from the coordinates of the player character.

That is, the viewpoint is fixed to the player character.

Accordingly, when the user moves the player character on the game map, the input processing means 110 receives the input, and the rendering processing means 120 displays the player character to walk or jump at the center of the screen according to user input, So that the game map is scrolled in the opposite direction in which the player character moves.

FIG. 4 conceptually explains the movement of the camera in accordance with the movement of the player character in the 3D game.

As shown in FIG. 4, as the player character moves, it can be seen that the camera moves along the player character.

However, when the player character approaches the edge of the game map within a predetermined distance, the rendering processing means 120 processes the camera so that the camera no longer moves along the player character.

Since the camera does not move along the player character, the player character is no longer fixed to the center of the screen.

Instead, the rendering processing means 120 stops moving the coordinates of the axis corresponding to the moving direction of the player character of the camera.

Fig. 5 is a diagram illustrating conceptually that the camera can no longer move at the edge of the game map. Fig.

The camera moves along the player character until the player character moves to the edge of the game map, but stops after the player character does not move along the player character.

In FIG. 5, while the player character is moving along the player character while moving the player character to the right side of the game map, it can be confirmed that the player does not move and stops when the player character approaches within a predetermined distance from the right end of the game map.

That is, as the x coordinate of the player character approaches a predetermined distance from the end of the game map while the y coordinate of the player character is fixed, the x coordinate of the camera no longer increases without increasing according to the x coordinate of the player character.

5, the player character is sufficiently distant from the top or bottom of the game map. Therefore, when the player character moves up and down in that state, the y coordinate of the camera moves in accordance with the increase / decrease of the y coordinate of the player character.

That is, as the x-axis coordinate of the player character approaches one end of the x-axis of the game map, the x-axis coordinate of the camera changes to a certain level and then stops. The y-axis is distinct from this.

In FIG. 5, it is assumed that the game map is a two-dimensional space described by x and y coordinates, but it may be a three-dimensional space having the z axis. In this case as well, when the player character approaches the end of the game map within a predetermined distance, It only stops the movement of the camera in relation to the axis.

Meanwhile, the rendering processing unit 120 may use the camera wall information to perform the processing.

The camera wall is an area indicating a range in which the camera can move along the player character, and is preferably set and stored in a game provided by the dead space removal apparatus 100 in the point-fixed 3D game according to the present invention.

The rendering processing means 120 further fetches the camera wall information at the time of loading the data of the game map and loads it into the memory,

When the player character moves according to a user's operation, the camera is moved along the player character, and when the player character moves out of the camera wall (that is, when the camera moves out of the camera month,

The coordinates of the corresponding axis of the camera are fixed to the coordinates reaching the camera wall in relation to the moving direction of the player character.

That is, as shown in FIG. 5, from the moment the camera reaches the camera wall, the camera can not move further along the x axis which is the moving direction of the player character.

On the other hand, when the user moves the player character back to the camera wall (that is, when the camera moves back to the inside of the camera wall) as opposed to the state shown in FIG. 5, the rendering processing means 120 interlocks the player character with the camera coordinates And processes the camera so that it moves along the player character again.

Thus, the player character can be fixed and displayed at the center of the screen again.

In addition to the above-mentioned method of determining the range in which the camera can move and invalidating the increase / decrease of coordinate values out of the range, the rendering processing unit 120 determines whether or not the player character is sufficiently close to the end of the game map, The same effect can be generated by calculating the coordinates of the camera in conjunction with the coordinates of the player character and then correcting the calculated value as follows.

That is, as the player character approaches the edge of the game map within the reference value, the rendering processing means 120 first calculates the coordinates of the camera in cooperation with the player character, and then calculates the coordinates of the camera by the distance (size) , And corrects the coordinates of the camera by moving it in the direction opposite to the moving direction of the player character.

As a result, the camera can not escape the camera wall as shown in Fig. 5 and stops at the boundary of the camera wall.

Conversely, when the player character is moved to the edge of the game map and then away from the edge of the road game map, the correction is performed in the opposite direction.

That is, first, the coordinates of the camera are calculated in cooperation with the player character, and then the coordinates of the camera are shifted in the direction opposite to the direction of movement of the player character so that the distance between the player character and the edge of the game map is distant, do.

Therefore, even if the player character moves away from the road game map, the camera does not move and stops at the boundary of the camera wall until the player character moves inside the camera wall.

When the distance between the player character and the edge of the game map coincides with the reference value, that is, when the coordinates of the camera calculated in association with the coordinates of the player character move to the inside of the camera wall, We render the game map and the objects on the map using the coordinates of one camera.

That is, the camera moves again along the player character, and the player character is fixed and displayed at the center of the screen.

Hereinafter, a dead space removal method in a point-fixed 3D game according to the present invention will be described in detail with reference to FIG. 6 to FIG.

[First Embodiment]

FIG. 6 is a flowchart illustrating a dead space removal method in a point-fixed 3D game according to an embodiment of the present invention.

One embodiment of the present invention limits the extent to which the camera can move using a camera wall as shown in FIG.

One embodiment of the present invention is executed in a game processing apparatus that processes a 3D game executed by moving a player character in a game map and rendering objects displayed through a camera in real time.

That is, it can be executed in a personal computer, a smart phone, a tablet computer and its equivalent, or an online game server.

First, when the game processing apparatus loads the game map into the memory, it fetches the camera wall information and further loads it into the memory (step a-1).

At this time, the camera wall defines a range narrowed inward by a certain distance from the edge of the game map.

Thereafter, the game processing apparatus moves the camera along the player character as the player character moves on the game map according to a user operation (step a-2).

At this time, as the player character moves out of the camera wall in step a-2 - strictly, the coordinates of the camera calculated in conjunction with the coordinates of the player character deviate from the camera wall, The coordinates of the axis corresponding to the moving direction of the middle player character are fixed to the coordinates of the point reached the camera wall.

That is, as shown in FIG. 5, as the player character approaches the end of the game map in the x-axis direction, the x-axis coordinate value of the camera is fixed to the coordinate value of the point reached the camera wall. That is, the increment of the x-axis coordinate value of the camera after reaching the camera wall is invalidated.

These operations can be handled with simple logic statements.

Accordingly, when the player character is sufficiently close to the end of the game map, the movement of the camera in relation to the moving direction of the player character is stopped, the player character is no longer displayed in the center of the screen, As shown in FIG.

Accordingly, it is possible to prevent the screen from being filled with the dead space, and the gamer can play the game while confirming the objects significant to game play by including his / her player character on the screen even at the end of the game map.

On the other hand, when the player character moves back into the camera wall according to the user's manipulation - strictly, when the coordinates of the camera calculated in conjunction with the coordinates of the player character move inside the camera wall, In association with the player character, the camera moves along with the movement of the player character (step a-3).

Thus, the player character can be fixed and displayed at the center of the screen again.

[Second Embodiment]

7 is a flowchart illustrating a dead space removal method in a point-fixed 3D game according to this embodiment of the present invention.

This embodiment of the present invention obtains the same result as the embodiment by correcting the coordinates of the camera as the player character approaches within a predetermined distance from the edge of the game map.

This embodiment also proceeds by moving the player character in the game map, and is executed in a game processing apparatus that processes a 3D game executed by rendering objects viewed through a camera in real time.

7, the game processing apparatus first calculates coordinates of the camera in conjunction with the coordinates of the player character in the game map (step b-1).

That is, as the player character moves within the game map, the camera moves along the player character. Therefore, the player character is fixedly displayed at the center of the screen.

Needless to say, it does not necessarily have to be fixed to the center depending on the design. Even so, the player character will be fixed and displayed at a specific position on the screen.

On the other hand, the game processing apparatus determines whether the distance between the player character and the edge of the game map is smaller than a reference value (step b-2).

If the distance between the player character and the edge of the game map becomes smaller than the reference value, the game processing apparatus moves the coordinates of the camera obtained by interlocking with the coordinates of the player character to the moving direction of the player character And is corrected by moving in the opposite direction in real time (step b-3).

Accordingly, the camera stops at the position of the camera wall as shown in Fig.

On the other hand, if the player character moves away from the edge of the game map according to the user's operation thereafter, the game processing apparatus sets the coordinates of the camera obtained by linking with the coordinates of the player character to the distance between the player character and the edge of the game map (Step b-4) by moving the player character in the direction opposite to the moving direction of the player character in real time.

On the other hand, if the distance between the player character and the edge of the game map becomes equal to the reference value (step b-5), the player character is moved far enough from the edge of the game map,

The game processing apparatus resumes use of the coordinates of the camera calculated in conjunction with the coordinates of the player character in the game map (step b-6). That is, the camera moves again along the player character, and the player character is fixed and displayed at the center of the screen again.

Meanwhile, the dead space removal method in the point-fixed 3D game according to the present invention can be embodied in the form of software, which is a set of instructions that can be read by a computer, and can be recorded on a recording medium.

In this case, the recording medium may include any type of medium readable by a computer, such as DVD-ROM, CD-ROM, hard disk, USB memory, and flash memory.

On the other hand, the expression to be recorded on the recording medium includes not only the case of being recorded on the recording medium of this type but also the case of being provided through a communication line in the form of an intangible carrier wave (Carrier Wave).

Although the expression 'player character' is used in the above description, it means an object operated by the user directly in the game, and is not necessarily limited to a human character or an avatar.

While the present invention has been described with reference to the accompanying drawings and embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. .

The present invention can be applied to the field of game technology.
