In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Unless defined otherwise, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

1. Overview

The main functions of the game engine are a rendering engine for rendering 3D graphics, a physics engine for detecting collisions in 3D space and realistic physics effects, ). Various functions such as a script editor and a map editor can be added to improve convenience and speed of development.

In the game development using the game engine according to the present invention, it is possible to develop a server and a client interlockingly through various functions peculiar to the present invention, and to solve a problem occurring between heterogeneous authoring environments such as other platforms, So that the function can be stably developed.

The present invention is based on a modular architecture that allows a developer to easily modify, extend and refactor the solution to meet the unique creative goals and vision of the game developer. In other words, even if it is developed on the basis of the existing authoring environment or developed on the basis of another authoring environment as needed, a plug-in module is provided as shown in FIG. 1, And the like.

The present invention takes into consideration a considerable decrease in processing time and server performance when a kernel-user mode is switched for processing a Transmission Control Protocol (TCP) and a User Datagram Protocol (UDP) packet in a server operating system Enables minimal kernel-user mode switching.

In the operating system, the operating system is prevented from being damaged by malicious code or the like at a low level of authority, and access to resources is allowed for each layer in order to structure a role for the hierarchy by determining what can be done for each hierarchy. Mode and kernel mode differ in access to resources. Application programs running in user mode can not invade other areas of the program because they are allocated virtual memory and are guaranteed to be independent of each other. They also run in user mode and therefore can not penetrate kernel space. However, applications running in kernel mode can freely use all memory. Therefore, in consideration of this, Kernel-User Mode switching is performed in a short time.

In order to prevent problems such as a client connection failure due to a structural problem of a game logic in a game having a network function, a user routine and a network I / O routine are provided in different thread pools thread pool).

In the distributed server configuration, if the relationship between the thread pool and the server instance is not one-to-many, the performance of the server may deteriorate due to an increase in the kernel time. And to develop a high performance game server with minimum kernel time.

2. Example

2 is a block diagram of a server and client integrated game authoring system according to the present invention.

As shown in FIG. 2, the server and client integrated game authoring system of the present invention includes a mobile multi-operating system build template 100, which is a means for providing various tools and source code for creating applications running on each platform, A template 200 and a server and a client game system 300 for driving an application generated through the templates 100 and 200 to play a game between the server and the client.

The server and client integrated game authoring system of the present invention may further include a mobile multi-operating system game development library 400, which is a means for collecting various tools necessary for creating the application, for example, animation, And a mobile multi-operating system game development server 500 that develops a game executed in multiple operating systems, such as generating server and client data using an application template and a game development library.

In the embodiment, the mobile multi-operating system build template 100 provides a variety of tools for developing applications that can be run in conjunction with various platforms, such as iOS, Android, Windows phone, and the like, As well as multi-platform layers.

The multi-platform layer provides a variety of tools to compile game application source code generated using the PC-based simulator and mobile multi-operating system game development library 400 to create applications that can be executed on each platform.

Application creation tools are operating systems and specific functions of software that run on hardware and hardware, and include tools such as Audio, DataBase, Animation Designer, Script Editor, admit.

In the embodiment, the application template 200 provides developers with formalized source code to facilitate initial framework creation and adaptation to an independent mobile solution. The source code includes, for example, game resources or logic, and corresponds to the basic design part of the game application, so that the developers can create basic frames of the game.

The game application source code is used to input the process of creating an application that runs on each platform and is compiled into an application running on each platform. That is, when a document written in a specific language is transferred to another programming language through a compiling program, for example, a multi-operating system game development library 400 compiled for an ARM-based CPU and a library 400 And links the start-up file for each platform to create an application that runs on each mobile device.

The application template 200 may provide a standard template for each platform. That is, if game data for each platform in the library 400 is processed and an application that can be run on each platform is generated, the application is stored as a standard template, and provided when a user requests the game.

Meanwhile, the standard template stored in the application template 200 may be transformed in a manner interlocked with the standard data for each mobile device. That is, when specific mobile device game data is requested for development of a game linked to a specific mobile device, the received game data is stored as mobile device standard data. When a standard template for a specific platform is requested from the game development server in this state, standard data for the mobile device is extracted according to the standard template. The extracted standard data of the mobile device may be included in the standard template to generate the mobile device standard template data and then provided to the game development server.

The information of the application template may include version information and template name information according to multiple operating systems. Therefore, these pieces of information can be information provided to the game development server. This means that only the specific data information requested by the user among the data information linked to the template information requested by the user can be provided to the game development server.

For example, when the application template type and at least one content are requested from the server through the GUI of the multi-platform layer, the template source code corresponding to the requested application template type is retrieved from the memory, and the retrieved template source code And a flow for generating the requested application based on at least one content.

The server and client game system 300 transmits the progress status of the mobile network game by driving the game application generated based on the mobile multi-operating system build template 100 and the application template 200 to the user do.

The game progress is performed by the server, and the processed result according to the game progress is transmitted to the client as an event type. The events sent to the client are processed and represented in a game environment, for example, graphics, animation, and sound, to enhance the user's game satisfaction.

The client also transmits the progress and status of the game to the user in the mobile network game. The client includes all devices capable of receiving contents through a network such as a mobile phone, a PC, and a set-top box.

Data processed by the server and client are defined as packet data and are networked with each other. Therefore, each packet data is processed through the event handler, and guides the user to process the event when the event occurs. The event defined by the packet data is divided into a proxy on the transmitting side and a stub on the receiving side to prevent confusion of the user.

The mobile network game progresses through a game loop when an input of a user is generated. The mobile network game progresses through a game loop, in which messages, graphics, and sounds are processed along with events transmitted through the network from the server, And is implemented by using device resources and writing game code. This is shown in Fig.

Device resource usage is provided through a system callback routine, and the user follows the code template to write the game code. Such as user input such as keyboard and mouse input, physical effects such as game state update such as map, animation, level, etc., collision inspection, music and sound effect reproduction, display and the like.

In the embodiment, the mobile multi-operating system game development library 400 is implemented by expressing dependency and hierarchical relationship among the main classes constituting the multi-operating system library. As shown in FIG. 5, basic functions such as resource management, object management, user interface, animation processing, and output used for game applications generated based on the build template 100 and the application template 200 are processed and managed . The library 400 can be managed in association with the source code generated and stored and managed thereby. That is, as described above, the type of the template requested by the user and the content to be associated with the source code are managed so as to be easily recognized.

Each of the libraries 400 is configured to be capable of parallel processing with respect to the requested functions, so that processing for resources that can be particularly concentrated in game development can be efficiently performed. For example, parallel processing with 10 processors can improve processing speed up to 10 times.

As a specific example, an animation library constructs various functions to describe the natural movement of characters and geometric objects in a game. Basic graphic data such as Material, Mesh, Texture, Transform, Shader, and Text are generalized through an animation composed of the above-mentioned hierarchical structure, and a complex animation can be represented through an iterative processing process. This process is shown in FIG. 6 as a block.

In addition, the user can define an animation event occurrence point such as a character fighting action, and synchronize an animation event and an event handler of the game system so as to be transmitted to an event of the game system.

Also, for realistic representation, for example, in the case of collision and collision response, it is processed in conjunction with a physical module for detecting collision of 3D space and realistic physics effect. Inter-communication with the physical module is defined as a client event of the game system, It is processed by the event handler of the system basically, and it can be modified by the user.

The game is typically programmed as a single game loop. Therefore, the complexity of things to be processed and processing, such as user input, display update, next animation frame processing, etc., is increasing. It is necessary to calculate these complicated problems quickly, output the response, and perform various input and output processes almost simultaneously. Given this, In the present invention, a game performance can be improved by using a mobile multicore processor.

As shown in FIG. 7, a thread pool including a plurality of threads is configured through a scheduler, and information can be exchanged with graphics renderers by processing the plurality of threads. Also, by using a large number of threads, data downloading and loading can be facilitated.

In addition, although PC-based middleware provides a parallel processing function, current mobile middleware does not. Therefore, in the present invention, rendering output and input / output for rendering 3D graphics are processed in parallel, .

Mobile games also include a variety of content, such as characters, items, weapons, and stores, which must be continually revised, supplemented, or added to meet consumer needs. However, it is not easy to modify and distribute mobile games. In order to do this, it is necessary to go through processes such as market correction registration, market inspection, and user distribution.

Accordingly, in the present invention, as shown in FIG. 8, the content maintenance efficiency is improved by facilitating such correction and supplementation through an installer (updater). In other words, only the necessary parts are downloaded at the minimum cost, maximizing user convenience.

In the embodiment, the mobile multi-operating system game development server 500 may be configured to allow the multi-operating system game development server 500 to use a different hardware having at least one hardware among hardware belonging to the platform, In a state where the platforms are connected to the network, a performance profile of the performance of the platform and a network state at each point of time is configured by the client and transmitted to the server. The server controls the corresponding network traffic for each client having the heterogeneous hardware platform, This creates an environment where multiple users can access and enjoy a single game in different environments.

To this end, the mobile multi-operating system game development server 500 includes a P2P communication module, a web service module, a DB Cache module, a distributed server processing module, and a server module.

The P2P communication module can be used to communicate with the client through a server to improve security from excessive traffic and hacking, such as when the amount of data is too large, when the client is far from the server, or when a better latency is required. Peer-to-peer networking allows client hosts to communicate directly with each other without going through the server.

Considering that mobile games are becoming more and more integrated with social websites gradually, web service modules can be used for browsing some information of games, for example, character information, auction sites, friend lists, guilds, Indexes and the like can be easily linked to the game server.

In addition, it enables the Http communication protocol directly with the web server, and automatically outputs the meta-script for the development environment such as JAVA or ASP.NET and automatically uses the environment as the local API of the corresponding language.

This environment can be realized by sharing account information between the web server and the game server while the client, the web server, and the online game server are networked with the internet network.

The DB Cache module supports free schema and constraint schemas and non-exclusive access functions in consideration of the fact that a large part of the game server process consumes database access time and complicates the game server's logic. The load balancer is configured as shown in Fig. 9 so as to enable safe and quick access.

The distributed server processing module needs to maintain the connection relationship between the client and the server even between the distributed servers configured to solve the problem that it is difficult to process a large number of concurrent users with one game server. Therefore, As in the case of the module, the authoring environment also uses a multi-core and processes it using an event callback user routine.

The distributed server process may include: communicating with a session of a client device to retrieve and update status information of a user stored on at least one server, storing the updated status information on at least one server, Retrieving the updated status information when continuing on the device and communicating with the other client device based on the updated status information in the continued session, As shown in FIG.

The server module minimizes the kernel time through the configuration of the thread pool as shown in FIG. 7, and can use one server process, the authoring environment, and the user-defined functions as multi-cores To maximize the use of multicore processors.

The mobile game development system of the present invention configured as described above has a structure as shown in FIG.

As shown in FIG. 10, a game is developed and edited using various tools configured in the planner, the programmer, and the designer, and the edited game is demonstrated by network communication between the server and the client of the client and the client, Events, and game progress scripts.

11, when game data is created, a more extended game model is created, converted into a data format optimized for the authoring environment, converted into data optimized for each platform, And has a flow that is confirmed through run-time operation while being demonstrated.

First, a graphical user interface (GUI) -based user interface is provided, and game data such as a character, a background, and a scene of a game can be created (S10). The game data is created using a multiple operating system build template 100 providing build tools for each platform and a library 400 providing game data elements.

Accordingly, the user enlarges the game data to be provided and creates a complicated game model (S20).

The game model data created by the user is converted into a data format optimized for error detection and authoring environment through a data generation process (S30). At this time, an event code that can be identified by the event manager is given for event processing such as animation. In addition, to track data history, add details such as version (for debug), creation date, and so on. The output data format can be output in various formats such as xml, html and the like through a separate output device in its own binary format, and the output format can be modified by the user.

The data output through the data generation process is finally converted into data optimized for each platform (S40). That is, the data is optimized for each platform using the source code for each platform provided through the application template 200, that is, converted into a game application.

The data converted and generated by the platform-specific game application is previewed through the game system (S50), and events and game progress scripts defined in the data are confirmed through a run-time operation (S60). The use of undefined events or data is detected and reported by the runtime (S70).

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. That is, within the scope of the present invention, all of the components may be selectively coupled to one or more of them. In addition, although all of the components may be implemented as one independent hardware, some or all of the components may be selectively combined to perform a part or all of the functions in one or a plurality of hardware. As shown in FIG. The codes and code segments constituting the computer program may be easily deduced by those skilled in the art. Such a computer program can be stored in a computer-readable storage medium, readable and executed by a computer, thereby realizing an embodiment of the present invention. As the storage medium of the computer program, a magnetic recording medium, an optical recording medium, a carrier wave medium, or the like may be included.
