detailed description

In order to solve the above technical problem, the general idea of the technical solution provided by the present invention is as follows:

In the technical solution of the embodiment of the present invention, when the broadcast device broadcasts the game, the game participation information sent by the webcast server for participating in the game is received; the game is run in the anchor device, The game participation information is transmitted to the webcast server by the viewing device that receives the live broadcast, and then the game participation information is transmitted to the game, and the game is participated and controlled based on the game participation information. Thus, it can be seen that by transmitting the received game participation information to the game and controlling the game based on the game participation information, it is achieved that the game is controlled based on information transmitted by the viewing user. Then, for the viewing user, by transmitting the game participation information in a webcast, the live game can be controlled, thereby implementing the game during the live broadcast of the game.

The technical solutions of the present invention are described in detail below with reference to the accompanying drawings and specific embodiments. It is understood that the specific features of the embodiments and the embodiments of the present application are the detailed description of the technical solutions of the present application, and are not limited to the technical solutions of the present application. In the case of no conflict, the technical features in the embodiments of the present application and the embodiments may be combined with each other.

The term "and/or" in this context is merely an association describing the associated object, indicating that there may be three relationships, for example, A and / or B, which may indicate that A exists separately, and both A and B exist, respectively. B these three situations. In addition, the character "/" in this article generally indicates that the contextual object is an "or" relationship.

In order to more clearly describe the method for controlling a game in the embodiment of the present invention, the network architecture to which the embodiment of the present invention is applied is first introduced. Please refer to FIG. 1 , which is a schematic diagram of a possible network architecture. As shown in FIG. 1 , in a live webcast, there may be one anchor device, and one or more viewer devices, and both the anchor device and the viewing device access the network live server through the network. The anchor plays the image and audio collection by the anchor device, and the collected image and audio are sent to the server by the anchor device. After the server parses and processes the image and audio, it sends the image and audio to all of the viewing devices.

In the embodiment of the present invention, the webcast is specifically a live game, that is, the image and audio include at least the image and audio of the game, and may further include an image and audio of the anchor. Both the webcast process and the game's progress run on the anchor device.

Each viewing user watches the game live on their own viewing device. Moreover, each viewing user can send viewing information such as a barrage, a comment or a gift to the server through his own viewing device.

A first aspect of the present invention provides a method for controlling a game. Please refer to FIG. 2, which is a flowchart of a method for controlling a game according to an embodiment of the present invention. The method includes:

S101: Receive, when the host device performs the live broadcast of the game, the game participation information sent by the webcast server for participating in the game;

S102: Send the game participation information to the game;

S103: Control the game based on the game participation information.

Specifically, in the live broadcast game of the embodiment of the present invention, the corresponding process runs in the anchor device. Further, if the game is specifically a network game, the anchor device can further access a game server different from the webcast server. The game participation information is used to control the game and then participate in the game. The game participation information in the embodiment of the present invention is further used to control any one of the plurality of game skills of one game character in the game. The game participation information is sent by any viewing user to the webcast server through the viewing device, and then forwarded to the anchor device by the webcast server. The game participation information may be sent in the form of a barrage, a comment, or a gift, and the present invention is not specifically limited.

In a specific implementation process, in order to avoid excessive viewing users participating in the game, one or more viewing users who can participate in the game may be selected in advance. In one embodiment, the viewing user who can participate in the game may be specified by the webcast server, or in other embodiments, may also be selected by the network anchor. According to the user identification of the viewing user who can participate in the game, the viewing information of the viewing user who can participate in the game is filtered out from all the received viewing information, and the viewing information including the game participation information is further filtered out.

For example, the game participation information is sent through the barrage, and the specific agreement is to add the type identifier of "skill" at the beginning of the barrage content, and then attach the skill number, the skill number indicates that the game participation information is to be controlled. Which game skill is it. Then, the viewing user who can participate in the game assumes that the game is played by transmitting the content of the "skill 1", thereby controlling the game character to use the first skill. Then, the live broadcast process receives all the viewing information, and filters out the "skill 1" barrage, and then acquires game participation information indicating that the game character is used to control the first skill.

In the above example, a plurality of game skills of the game character may be numbered in advance and presented to the viewing user in order to view the user sending an accurate skill number.

Then, in S102, the live broadcast process transmits the game participation information to the game progress, thereby transmitting the game participation information to the game. Finally, in S103, the game is controlled based on the game participation information.

As can be seen from the above description, by transmitting the received game participation information to the game and controlling the game based on the game participation information, it is realized that the game is controlled based on the information transmitted by the viewing user. Then, for the viewing user, by transmitting the game participation information in the webcast, the live game can be controlled, thereby realizing the participation in the game during the live broadcast of the game.

The following describes the specific implementation of transmitting game participation information to the game.

Specifically, in the embodiment of the present invention, the live process and the game process are all running on the anchor device, as shown in FIG. 3, which is a schematic diagram of the live process and the game process. In order to control the game according to the game participation information sent by the viewing user, it is necessary to send the game participation information in the anchor process to the game process across threads. To implement communication between different processes, the specific implementation manner of the present invention is:

Named Pipes Named Pipes is an interprocess communication mechanism that supports reliable, one-way, or two-way data communication between different processes on the same computer or between different processes across different computers on a network. It shields the underlying network protocol details.

In order to realize the communication between the live process and the game process, as shown in FIG. 3, the embodiment of the present invention constructs a named pipe in the live process and the game process, and after the completion of the construction, the game participation information of the live process is sent to the game process through the named pipe. .

Among them, the specific implementation of building a named pipe is as follows:

Specifically, the naming pipeline includes two ends. In the embodiment of the present invention, one end that injects the live broadcast process and sends the game participation information is referred to as a “server”, and one end that is injected into the game process and receives the game participation information is referred to as “client”.

First, the live process calls the named pipe system function of the anchor device to create a named pipe, and the server that creates the named pipe is injected into the live process. Then, wait for the client to connect.

For example, the host device is specifically a PC running Windows. The live process calls the CreateNamedPipe function in the Windows API (Application Programming Interface) function to create a named pipe. In the specific implementation process, the name of the named pipe can be customized to a unique name. Then call the connection named pipe ConnectNamedPipe function to wait for the client connection.

When the anchor device is running other devices of other systems, such as a mobile phone running Android, the corresponding system function is called to create a named pipe, which will not be described here.

For the client of the named pipe, the game program in the anchor device is a published program, and the client cannot be directly created. Therefore, the embodiment of the present invention injects a preset program into the game process, and the logic of the preset program is loading the client. end. Therefore, the preset program is run in the game process, so that the preset program loads the client, and then the client of the named pipe is injected into the game process. Then, the client connects to the server in the live process according to the name of the named pipe, thereby completing the construction of the named pipe between the live process and the game process.

Among them, injecting a preset program into the game process is implemented by the following process:

Providing the game process with a disk path of the preset program;

The preset program is loaded in the game process according to the disk path.

More specifically, injecting a preset program into the game process is accomplished by the following process:

Allocating a preset space in a memory space of the game process;

Writing a disk path of the preset program into the preset space;

Creating a remote thread for injecting the preset program based on the disk path in the game process;

Run the remote thread.

Following the example above, the anchor device is a PC of Windows system. The anchor device allocates preset memory in the memory space of the game process through the VirtualAllocEx function in the Windows API function. Among them, the role of the VirtualAllocEx function is to reserve or commit the memory area in the virtual space of the specified process. Then, the disk path of the preset program is written to the preset memory through the WriteProcessMemory function in the Windows API function. Among them, the function of the WriteProcessMemory function is to write to the memory area of a certain process. Next, create a remote thread in the game process by calling the Create Remote Thread CreateRemoteThread function in the Windows API function. Among them, a remote thread represents a thread created by one thread in another thread. The logic executed by the remote thread in the embodiment of the present invention loads the disk path written into the preset memory by calling the LoadLibrary function, and loads the preset program in the game process according to the disk path, thereby injecting the preset program into the game process. Among them, LoadLibrary The function is used to load the specified dynamic link library and map it to the address space used by the current process.

Through the above embodiment, the preset program is injected into the game process. Then the default program is run during the game process, thereby loading the client in the game process, and then injecting the client into the game process.

It can be seen from the above description that by injecting a preset program for loading the client into the game process, the client is injected indirectly in the game process, thereby realizing the participation of the user and the control is effective.

The loaded client further needs to connect to the server to receive the game participation information of the live process. Specifically, after the client is loaded, the server is searched for and connected to the named pipe according to the named pipe name included in the preset program, and after the server is connected, the server client is notified that the connection has been completed. Enables the server to start sending game participation information.

Following the example above, the anchor device is a PC of Windows system. The loaded client calls the CreateData function to connect to the named pipe, and calls the wait named pipe, WaitNamedPipe function to monitor and wait for the server's response. After connecting to the server according to the name of the named pipe, the client calls the write data WriteFile function to write data to the server pipeline indicating that the client has completed the connection. Then, the read data ReadFile function is called to read the game participation information received in the named pipe. On the other hand, the server waits for the client connection of the named pipe through the ConnectNamedPipe function, and calls ReadFile to read the data sent by the client indicating that the client has completed the connection, and then determines that the named pipe is completed. Then, the server side calls the WriteFile function to write all the game participation information acquired by S101 into the named pipe.

Next, how to control the game based on the game participation information in S103 is introduced. In the embodiment of the present invention, S103 is implemented by the following process:

The game function is called and executed to control the game.

Specifically, since the user participates in and controls the game, specifically by calling a game function in the game, in order to call the corresponding game function, it is necessary to determine the game function that the game participation information needs to call.

In one embodiment, all game functions may be pre-fetched and a mapping relationship between each game function and game participation information is established. Then, the live broadcast process receives the game participation game, and can determine the game function required to be called by the game participation information according to the mapping relationship, thereby calling and executing the game function required to be called by the game participation information in the game process through the named pipe.

For example, the game participation information is specifically “skill 1”, and the game function corresponding to the first skill of the game character is determined as the function A according to the mapping relationship. Therefore, function A is called through the named pipe, which in turn causes the game character to use the first skill.

As mentioned above, since the game program in the anchor device is a published program, it is not convenient to obtain the game. Play function. According to experience, the skill control object of the game character will store a pointer in the game character object, and the pointer can be found in the character object to further find the game function that realizes the skill. Once you have found the game function, you can determine the parameters that need to be passed, the conditions under which the function is used (such as CD cooling time or whether the energy bar of the skill is full, etc.) and call the game function. Thus, in another embodiment, the game function is invoked by calling assembly language using disassembly.

Specifically, the embodiment of the present invention searches for a game function that needs to be called by the game participation information through a dynamic debugging tool such as WinDbg, and parameters that need to be used to use the game function. Windbg is a user-mode and kernel-mode debugging tool for the Windows platform. It is a lightweight debugging tool compared to Visual Studio. For example, the game function is determined and called by inline assembly code as follows.

__asm

{

Push SpellIndex / / press the index number of the skill into the stack

Mov ecx, SpellThis / / incoming ecx bit skill management object instance pointer

Call CastSpell / / call the game function

}

SpellIndex is the skill index number. For example, the index number corresponding to "skill 1" above is 1.

The values of SpellThis, JudgeCastSpell and CastSpell are memory addresses, which are found by WinDbg dynamic debugging analysis. The incoming ecx register is the address of the game function that has been instantiated. Finally, the game function is called by the assembly instruction call.

In the specific implementation process, other disassembled code can also be written to call the game function, and the present invention does not impose any specific limitation.

Further, if the calling game function is conditional, before executing the above code, it is judged by the following code whether the condition for calling the game function is satisfied.

__asm

{

Push SpellIndex / / press the index number of the skill into the stack

Mov ecx, SpellThis / / incoming ecx bit game function instance pointer

Call JudgeCastSpell / / call the game function

Mov Ret, eax / / will store the return value of the judgment result in the Ret

}

If the value in the Ret is True, it means that the condition of the calling game function is satisfied, and then the code of the disassembled calling game function in the above is called and executed.

Based on the same inventive concept as the method for controlling a game in the foregoing embodiment, the second aspect of the present invention further provides a device for controlling a game. As shown in FIG. 4, the method includes:
