Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a file obtaining method according to the present invention is shown, and is applied to a terminal including a path container, where the path container includes a virtual path corresponding to each file, and the method specifically includes the following steps:
in an online game or a stand-alone game, a game operator often develops a plurality of different game expansion packages, and the game expansion packages can comprise data packages such as game playing expansion, game pictures, game special effects, game audio and the like, so that a user can select to load different game expansion packages according to the requirement of the user or the configuration capacity of a terminal.
For example, when a user wants a game picture with high definition or a gorgeous skill special effect, the corresponding game expansion package can be downloaded, and the terminal reads the corresponding resource file, so that the terminal can display the game picture with high definition or the gorgeous skill special effect for the user.
It should be noted that, in the embodiment of the present invention, a game application is taken as an example for illustration, and it may be understood that the extension package may also be a resource extension package of other types besides the game resource extension package, which is not limited in this respect.
In the embodiment of the present invention, the present invention may be applied to a terminal, where the terminal may include a mobile device, and specifically may include a mobile phone, a Personal Digital Assistant (PDA), a laptop computer, a palmtop computer, and the like, and may also include a fixed device, and specifically may include a desktop computer, a vehicle-mounted terminal, an intelligent home, and the like, which is not limited in this embodiment of the present invention.
These terminals may support operating systems such as Windows, Android (Android), IOS, Windows phone, and the like, may also support embedded systems, and may generally run game applications.
In a specific implementation, a path container may be provided in a file system of the terminal, and virtual paths of the extension packets may be stored in the path container. The virtual path may be stored in a key-value pair manner, for example, the key may be a virtual path, and the value may be a relative path corresponding to the virtual path.
For example, the virtual path and the relative path of the development package may be represented in pseudo code:
'hero\1001':'extend\hero_xxx\1001'
'sound':'extend\sound_xxx'
the 'hero \1001' and the 'sound' may be virtual paths, and the 'extended \ hero _ xxx \1001' and the 'extended \ sound _ xxx' may be relative paths, and the relative paths may be dynamically changed along with changes of the extension packets.
Specifically, when the terminal receives a resource switching instruction of the user, the first path of the current file may be obtained first. The current file is a resource file loaded by the current terminal, and may include an audio file, a game screen file, a game special effect file, and the like. When the user wants to load resource files of the same type and different qualities, the terminal may respond to the switching instruction of the user and then acquire the file path of the current file.
In an example of the embodiment of the present invention, when a user wants to switch to a high-quality game audio, the terminal may first obtain a file path of a current audio file, for example, the file path may be sound \ bgm \ music.
in the embodiment of the present invention, after the terminal acquires the first path of the current file, the first path may be adopted, and in the path container, whether a target virtual path that is the same as the file type of the current file and corresponds to the first path exists is searched.
In a specific implementation, when a target virtual path corresponding to the first path exists in the path container, it indicates that a target file corresponding to the current file exists, and then the terminal may further obtain a relative path corresponding to the target virtual path. The relative path may be a file path for acquiring the target file.
And 103, reading the target file corresponding to the relative path.
In a specific implementation, after the terminal obtains the relative path for obtaining the target file, the corresponding target file can be read by using the relative path, and the target file is loaded, so that the file is dynamically read through the virtual path stored in the path container and the relative path corresponding to the virtual path in the file obtaining process, an application layer does not need to care about the problem of file path replacement, the cost of terminal performance is reduced, excessive logic processing is not needed to be performed on a logic layer, and the maintenance cost of the logic layer is reduced.
When the path container does not have the target virtual path corresponding to the first path, the terminal may replace the first path with the file path of the target file in a file path replacement manner, and read the corresponding resource file.
In an example of the embodiment of the present invention, a current file in a game application program is a default audio file, and when a user wants to set and use a medium-quality audio file, a terminal may respond to a setting instruction of the user to obtain a file path of the current audio file, which is sound \ bgm \ music. Then, the terminal may search whether a target virtual path corresponding to the file path exists from the path container, and when the target virtual path corresponding to the file path exists, such as 'sound', a relative path corresponding to the target virtual path may be extracted as 'extended \ sound _ middle', and then the relative path may be adopted to read and load an audio file of medium quality, so that the file may be dynamically read through the virtual path and the relative path corresponding to the virtual path, so that the application layer does not need to care about the problem of file path replacement, the overhead of terminal performance is reduced, excessive logic processing does not need to be performed on the logic layer, and the maintenance cost of the logic layer is reduced.
In the embodiment of the invention, the method is applied to the terminal comprising a path container, by acquiring the first path of the current file, when a target virtual path corresponding to the first path exists in the path container, extracting a relative path corresponding to the target virtual path, then reading the target file corresponding to the relative path, and dynamically reading the file through the virtual path stored in the path container in the file acquisition process through the virtual path and the relative path corresponding to the virtual path, so that an application layer does not need to care about the problem of file path replacement, the cost of terminal performance is reduced, excessive logic processing does not need to be performed on a logic layer, and the maintenance cost of the logic layer is reduced.
Referring to fig. 2, a flowchart illustrating steps of an embodiment of a file obtaining method according to the present invention is shown, and is applied to a terminal including a path container, where the path container includes a virtual path corresponding to each file, and the method specifically includes the following steps:
in the embodiment of the invention, when a user wants to set the terminal to use different extension files, the terminal can respond to a setting instruction of the user, and acquire the first path of the current file and the second path of the target file.
In a specific implementation, when the terminal receives a resource switching instruction of a user, a first path of a current file may be obtained first. The current file is a resource file loaded by the current terminal, and may include an audio file, a game screen file, a game special effect file, and the like. The target file may be a file of the same file type as the current file, for example, when the current file is an audio file, the target file is an audio file.
in the embodiment of the present invention, the path container stores the virtual path corresponding to each extension packet. The same type of expansion package can comprise multiple data packages with different qualities, the expansion packages with different qualities can correspond to the unique file path, for example, the audio expansion package can comprise data packages with default quality audio, medium quality audio, high quality audio and the like, the game picture expansion package can comprise data packages with smooth quality, high definition quality, ultra-definition quality, 4k quality and the like, and each data package corresponds to the unique file path.
For example, the file path for high quality audio: sound _ high \ bgm \ music.bnk, file path of medium quality audio: sound _ middle \ bgm \ music.
In specific implementation, files of the same type in the path container correspond to the same virtual path, the same virtual path may correspond to different relative paths, and the relative paths may dynamically change along with the file path of the target file. The terminal may first search for a target virtual path corresponding to the target file from the path container after acquiring the second path of the target file, and may acquire an original relative path corresponding to the target virtual path after the target virtual path corresponding to the target file exists, so as to dynamically update the original relative path according to the second path.
in a specific implementation, the terminal may extract a characteristic path corresponding to the target file from the second path, and then replace the original relative path with a target relative path corresponding to the characteristic path.
Specifically, the file paths of the same type of file may be distinguished according to different quality features, for example, for an audio file, the audio file may include default audio, medium-quality audio, high-quality audio, and the like, and the corresponding file paths are respectively:
file path for high quality audio: sound _ high \ bgm \ music
File path for medium quality audio: sound _ middle \ bgm \ music
File path for default quality audio: sound \ bgm \ music
The feature path may be "sound _ high", "sound _ middle", and "sound", among others. After the terminal obtains the second path of the target file, the characteristic path can be extracted from the second path, and then the relative path in the virtual path is updated. For example, the virtual path and relative path corresponding to an audio file are: ' sound ': extended \ sound _ xxx ', according to the characteristic path ' sound _ middle ' in the second path, the ' sound _ xxx ' can be updated to ' sound _ middle ', so that the relative path is updated to the file path corresponding to the target file.
in a specific implementation, when a target virtual path corresponding to the first path exists in the path container, indicating that a target file corresponding to the current file exists, the terminal may further obtain a relative path corresponding to the target virtual path. The relative path may be a file path for acquiring the target file.
In an alternative embodiment of the present invention, a virtual path may be searched from the path container according to the file directory depth, and then step 204 may include the following sub-steps:
substep S11, obtaining a directory depth of the relative path;
in a specific implementation, the directory depth of the relative path may be set according to a file directory of the resource file. The file directory of the resource file can be composed of multiple levels of directories, and multiple levels of sub-directories can be included under the parent directory, so that the directory depth of the relative path can be determined according to the characteristic path in the file path of the resource file as a node, wherein the parent directory comprises the characteristic path and the characteristic path at each level.
In an example of the embodiment of the present invention, a file path of an audio file is taken as an example for description, when the file path of the audio file is sound \ bgm \ music.bnk, and a corresponding characteristic path is "sound", which includes a primary directory, then the directory depth is 1, and a relationship between a virtual path and a relative path in a path container may be ' sound ': extended \ sound _ xxx '; when the file path of the audio file is sound \ sound _ changjing \ bgm \ music.bnk, and the corresponding characteristic path is sound \ sound _ changjing ", which represents the scene audio in the audio, that is, the user can select the quality of the scene audio, the directory depth is 2, and the relationship between the virtual path and the relative path in the path container can be ' sound ': extended \ sound \ sound _ changjing _ xxx ', etc., so that the directory depth of the relative path can be dynamically adjusted according to the path depth of the resource file, thereby improving the applicability of file matching and ensuring the uniqueness of file reading.
It should be noted that, the embodiment of the present invention includes, but is not limited to, the foregoing examples, and it is understood that, under the guidance of the idea of the embodiment of the present invention, a person skilled in the art may set a file path of a relative path according to an actual situation, and the present invention is not limited to this.
Specifically, in the process of searching for the file, the terminal may first obtain the directory depth of the target relative path from the path container, so as to determine whether the target virtual path corresponding to the first path exists in the path container according to the directory depth.
A substep S12 of extracting a target directory corresponding to the target depth from the first path;
in a specific implementation, after the directory depth of the relative path is obtained, a target directory corresponding to the target depth may be extracted from the first path.
In an example of the embodiment of the present invention, the current file is an audio file, the first path is sound \ bgm \ music.
In another example of the embodiment of the present invention, the current file is an audio file, the first path is sound \ sound _ changjing \ bgm \ music.
And a substep S13 of extracting a relative path corresponding to the target virtual path when the target virtual path corresponding to the target directory exists in the path container.
In a specific implementation, after the target directory corresponding to the first path is determined, the target directory may be used to search whether a corresponding target virtual path exists from the path container, and when a target virtual path corresponding to the target directory exists, the terminal may further obtain a target relative path corresponding to the target virtual path.
In a specific implementation, after the terminal obtains a target relative path for obtaining the target file, the terminal may adopt the target relative path, read the corresponding target file, and load the target file.
In an alternative embodiment of the present invention, step 205 may comprise the following sub-steps:
a substep S21 of replacing the target directory with the relative path and generating a target path for the target file;
and a substep S22 of reading a target file corresponding to the target path.
In a specific implementation, after the terminal obtains the target relative path, the target relative path and the first path may be adopted to generate a target path for acquiring the target file. Specifically, the target directory in the first path may be replaced by a target relative path, so as to obtain a real file path of the target file, and then the target file is read from the target path, so that the file is dynamically read through the virtual path and the relative path corresponding to the virtual path in the file acquisition process through the virtual path stored in the path container, so that the application layer does not need to concern about the problem of file path replacement, the overhead of terminal performance is reduced, excessive logic processing does not need to be performed on the logic layer, and the maintenance cost of the logic layer is reduced.
In an example of the embodiment of the present invention, a current file in a game application program is a default audio file, and when a user wants to set and use a medium-quality audio file, a terminal may respond to a setting instruction of the user to obtain a file path of the current audio file, which is sound \ bgm \ music. Meanwhile, the file path of the audio file with medium quality is determined as sound _ middle \ bgm \ music.
Then, in the path container, finding a virtual path corresponding to the audio file: 'found': extended \ found _ xxx ', updates the virtual path to' found ': extended \ found _ middle' according to the characteristic path, and the directory depth is 1.
The terminal can extract a target directory from the first path according to the target depth to be "sound", and adopt the target directory to search whether a target virtual path corresponding to the file path exists in the path container, when the target virtual path 'sound' is searched, a target relative path corresponding to the target virtual path can be extracted to be 'extended \ sound _ middle', then the target relative path can be adopted to replace the 'sound' in the first path to obtain a target path of a medium-quality audio file which is extended \ sound _ middle \ bgm \ music.bnk, and then the medium-quality audio file is read from the target path and loaded, so that the file is dynamically read through the virtual path and the relative path corresponding to the virtual path, the problem of file path replacement is not needed by an application layer, the performance of the terminal is reduced, and excessive logic processing is not needed by the logic layer, the maintenance cost of the logic layer is reduced.
In addition, when the user wants to set a high-quality audio file, the terminal may update the virtual path in the path container, for example, may update 'sound' extended \ sound _ middle 'to' sound 'extended \ sound _ high', thereby implementing dynamic path management and improving convenience of file management.
It should be noted that, the embodiment of the present invention includes but is not limited to the foregoing examples, and it is understood that, under the guidance of the idea of the embodiment of the present invention, a person skilled in the art may set the type of the file, the type of the application program, the terminal, and the like according to the actual situation, and the present invention is not limited to this.
In the embodiment of the invention, the method is applied to the terminal comprising a path container, by acquiring the first path of the current file, when the target virtual path corresponding to the first path exists in the path container, the relative path corresponding to the target virtual path is extracted, then the target file corresponding to the relative path is read, and the file is dynamically read through the virtual path stored in the path container and the virtual path corresponding to the virtual path in the file acquisition process, so that an application layer does not need to care about the problem of file path replacement, the cost of terminal performance is reduced, excessive logic processing does not need to be carried out on a logic layer, and the maintenance cost of the logic layer is reduced.
