Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a game data acquisition method, which is applied to a game process, and the flow chart of the method is shown in figure 1, and comprises the following steps:
s10, loading a dynamic link library, wherein a game version determination rule is stored in the dynamic link library;
a Process (Process) is a running activity of a program in a computer on a data set, is a basic unit of resource allocation and scheduling of a system, and is the basis of an operating system structure. The game process refers to a game program currently in progress; the game live broadcast process is a client process and is used for executing game data generated by the game process.
In this embodiment, the dynamic link library is a dynamically loadable file, i.e., a DLL file, which contains codes and data used by a plurality of programs at the same time, and is generally stored in C: under the Windows \ System directory. At present, in the microsoft Windows operating system, many application programs are not a complete executable file, and need to be divided into relatively independent dynamic link libraries to be placed in the system, and when a certain program is executed, the corresponding dynamic link will be called.
In the embodiment, a customized game version determination rule is recorded in the dynamic link library, and in a specific implementation process, the step S10 "load the dynamic link library" may specifically adopt the following steps, and a flowchart of the method is shown in fig. 2:
s101, receiving a virtual memory address written by an operating system, wherein the virtual memory address is pre-allocated to a game process by the operating system;
the embodiment is implemented based on tools provided by the microsoft windows operating system. Under the Win32 operating system, each process has its own virtual address space. Therefore, before the game process loads the target dynamic link library, the microsoft windows operating system may open up a virtual memory for the game process, specifically, the microsoft windows operating system needs to send the virtual memory address allocated to the microsoft windows operating system to the game process, and the game process searches the virtual memory according to the address.
S102, in the process of receiving the remote injection of the operating system into the dynamic link library, dynamically loading the dynamic link library into a virtual memory corresponding to the virtual memory address;
in this embodiment, the microsoft windows operating system can utilize the remote injection technology to realize remote injection of the dynamic link library. Exe is a part of microsoft Windows operating system, and is used for processing WMI operations through winmgmt exe programs, which are very important for the normal operation of a computer system.
In addition, once the microsoft windows operating system releases the virtual memory, the target dynamic link library injection is completed, so that once the game process detects the release of the virtual memory, the dynamic link library can be stored in the self storage directory.
S20, determining the game version type of the game process based on the game version determination rule;
at present, games of microsoft Windows operating systems are developed based on COM components of microsoft DX interfaces, and the versions of DirectX (Direct eXtension, hereinafter referred to as DX) used in game development are different, for example, DX8, DX9, DX10, DX101, and DX11 … …, so compatibility is required for different DX versions.
In a specific implementation process, in step S20, "determine the game version type of the game process based on the game version determination rule", the following steps may be specifically adopted, and a flowchart of the method is shown in fig. 3:
s201, acquiring a preset version type and a creation time sequence of the preset version type from a game version determination rule;
in this embodiment, the version type and the creation timing of the interface object to be created are not limited, and may be specifically set according to actual needs, for example, the version type and the creation timing of DX8, DX9, DX10, DX101, and DX11 … … are sequentially created.
S202, creating an interface object with a preset version type according to a creation time sequence;
s203, if the creation is successful, determining the preset version type as the game version type corresponding to the game progress.
In this embodiment, the interface object is an object that implements an interface. The interface is generally defined by keywords set by developers, and each game version type corresponds to an interface object, for example, the interface object corresponding to DX8 is "idiect 3DDevice8 Ex", and the interface object corresponding to DX9 is "idiect 3DDevice9 Ex". Only interface objects of the same type as the game version of the game process can be created successfully. In the process of creating the interface object, if a correct response value returned by the operating system is received, the game process indicates that the interface object is successfully created.
S30, creating shared memory content according to the game version type, so that the game live broadcast process obtains the game data generated by the game process based on the shared content;
in this embodiment, the game process may use the windows shared memory technology provided by the microsoft windows operating system to create the shared memory space. The contents stored in the shared memory are different for different game version types. For example, for a game version type of DX8, the shared memory content is game data, and for a version type other than DX8, such as a game version type of DX9, DX10, or DX11, the shared memory content is a texture handle.
In the actual application process, the game process uses the inline Hook, namely, a JMP instruction is added to realize the mode that the COM object virtual Function jumps to the user-defined Function to create the shared memory content.
In a specific implementation process, step S30, "create a shared memory content according to a game version type, so that a game live broadcast process obtains game data generated by a game process based on the shared content" may specifically adopt the following steps, and a flowchart of the method is shown in fig. 4:
s301, creating a shared memory space;
in this embodiment, the game process may use a windows shared memory technology provided by the microsoft windows operating system to create a shared memory space. The size of the shared memory space, the unit for storing data, and the like are not limited in this embodiment, and the user can specifically set the size according to actual needs.
In this embodiment, the version types of non-DX 8 are DX9, DX10, DX101, and DX11 … …. In the Microsoft Windows operating system, DX8 is implemented differently than non-DX 8 version types of interfaces.
S302, judging whether the game version type is DirectX 8; if yes, go to step S303; if not, go to step S304;
s303, acquiring video memory data from the memory of the graphics processor, converting the video memory data into game data generated by a game process, and storing the game data in a shared content space so as to enable a game live broadcast process to acquire the game data from the shared content space;
in this embodiment, the DX8 version type processes data in a manner of sharing memory data. Sharing memory data is achieved through a memory copy technique, i.e., a way in which multiple processes share the same memory.
S304, storing the preset texture handle in the shared memory space, so that the game live broadcast process acquires the preset texture handle from the shared memory space, acquires video memory data from the memory of the graphics processor by using the preset texture handle, and converts the video memory data into game data generated by the game process;
in this embodiment, the version type of non-DX 8 handles data in the manner of shared texture handles, which is implemented by shared handle technology, i.e., multiple processes share the same texture handle.
In addition, after the game live broadcast process acquires the game data, the game data can be converted into textures through a rendering technology, and the textures are pushed to the server side for display.
The above steps S101 to S102 are only one preferred implementation manner of the process of "loading dynamic link library" in step S10 disclosed in the embodiment of the present invention, and the specific implementation manner of this process may be arbitrarily set according to its own requirements, and is not limited herein.
The above steps S201 to S203 are only a preferred implementation manner of the process of "determining the game version type of the game progress based on the game version determination rule" in step S10 disclosed in the embodiment of the present invention, and the specific implementation manner of this process may be arbitrarily set according to the needs of the user, and is not limited herein.
The above steps S301 to S304 are only a preferred implementation manner of the process of step S30, namely creating the shared memory content according to the game version type so that the game live broadcast process obtains the game data generated by the game process based on the shared content, and the specific implementation manner of the process may be arbitrarily set according to the needs of the user, which is not limited herein.
