Technical Field

The embodiment of the application relates to the field of virtual environments, in particular to a method, a device, equipment and a medium for transplanting an application program.

Background

A child application is a program that runs in dependence on a parent application, also called an applet. Under the condition that the primary application program is installed on the electronic equipment, the small program does not need to be manually downloaded and installed in the electronic equipment by a user, and can be automatically downloaded and installed only after the user clicks an icon in the primary application program. A mini-game is a category of applets that have a light experience of playing on demand.

Many games are developed by third party engines and cannot be run directly on small game platforms. When a game developed by a third party engine is desired to run on a mini-game platform, the developer is required to redevelop the game on the mini-game platform.

The game with the same game content is re-developed once on the small game platform, which wastes the development results which are already carried out in the earlier stage and causes unnecessary resource waste.

The method may be applied in the first terminal 120 shown in fig. 1. The method is used for migrating a first application program into a second application program, wherein the second application program is a sub application program which runs by depending on a parent application program. The method comprises the following steps:

step 202, transforming a first application program from a first project mechanism to a second project mechanism through engineering transformation in a third-party development tool;

the first project mechanism is a project mechanism corresponding to a third party development tool, and the second project mechanism is a project mechanism corresponding to a sub-application. Optionally, the first application is an application developed by a third party development tool, relating to the virtual environment. For example, the first application is an educational application or a military simulation application. Optionally, the first application is provided with a virtual environment.

As can be appreciated in conjunction with fig. 5, a developer is engineering a first application 10 in a third party development tool 20. The first application 10 is modified from the project mechanism corresponding to the third party development tool 20 to the project mechanism corresponding to the sub-application.

Step 204, converting the art resources in the modified first application program from the first resource format to the second resource format, and exporting the converted art resources to a development tool of the sub-application program;

the first resource format is a resource format corresponding to a third party development tool. The second resource format is a resource format corresponding to a development tool of the sub-application.

Step 206, converting the code resources in the modified first application program from the first programming language to the second programming language, and exporting the code resources to a development tool of the sub-application program;

the first programming language is a programming language corresponding to a third party development tool, such as C #. The second programming language is a programming language corresponding to the sub-application, such as a JavaScript scripting language.

And 208, performing secondary development on the art resources and the code resources in the development tool of the sub-application program to obtain a second application program.

As can be seen from fig. 3, the developer exports "art resources + code resources" from the third-party development tool 20, imports "art resources + code resources" into the development tool 30 of the sub-application,

in summary, in the method provided in this embodiment, a first application program is first engineered in a third-party development tool, and then the art resources and the code resources in the first application program after the engineering are derived into a development tool of a sub-application program, and the art resources and the code resources are secondarily developed in the development tool of the sub-application program, so as to obtain a second application program; the development work of the first application program which is developed in the third-party development tool can be reused, the development process with more repetitive work is not needed to be restarted, the workload of developers can be saved, and a large number of existing application programs can be quickly transplanted to a small program platform.

In the following embodiments, the third party development tool is a Unity engine, the child application is a mini-game, and the parent application is an instant messaging program (such as WeChat), but the specific types of the three are not limited.

Fig. 6 is a flowchart illustrating an application migration method according to an exemplary embodiment of the present application. The method may be applied in the computer device 100 shown in fig. 1. The method is used for migrating a first application program into a second application program, wherein the second application program is a sub application program which runs by depending on a parent application program. The method comprises the following steps:

601, in a third-party development tool, modifying a first project structure of a first application program into a second project structure through engineering modification;

and a developer reconfigures the first project structure of the first application program in the Unity engine through engineering transformation and modifies the first project structure into a second project structure corresponding to the small program.

Optionally, the project structure comprises a catalog configuration of the project. Project structures include, but are not limited to: at least one of a root directory, a resource folder, a library folder, a project setting folder, a temporary folder, a configuration folder, an editor storage folder, an external library file storage directory, an art resource storage folder, a material ball folder, a model folder, an animation file folder, a sound file folder, a mapping file folder, a user interface file folder, a third party package file folder, a scene file storage directory, and a script storage directory.

Taking the third-party development tool as a Unity engine as an example, the first application program developed by the Unity engine is usually a client-side game, and art resources and code resources required by the client-side game are both stored in the first terminal. The mini-game is usually an online network game, art resources and code resources required by the mini-game are stored in the sub-application server and are loaded and operated by the second terminal in real time, and project mechanisms of the two are greatly different. Therefore, the project structure in Unity needs to be adapted.

Optionally, the developer also installs three plug-ins in the third party development tool: a resource export plug-in, a code export plug-in, and an SDK (Software Development Kit). The resource export plug-in is used for exporting art resources, the code export plug-in is used for exporting code resources, and the SDK is used for providing code functions which are not supported by a third-party development tool but are supported by the sub-application program.

Step 602, in a third-party development tool, accessing the first application program to an SDK, wherein the SDK provides a code function which is not supported by the third-party development tool and is supported by a development tool of the sub-application program;

because of the difference between the third party development tools and the development tools of the sub-applications, there are some code functions that are not supported by the third party development tools, but the sub-applications are supported code functions. For the code functions specific to these sub-applications, the SDK is provided in a third party development tool.

And the developer adds a code function which is exclusively supported by the sub-application program into the first application program by using the SDK in the third-party development tool. Optionally, the SDK is written in a programming language supported by a third party development tool, such as a C # SDK.

Optionally, the SDK supported code functions include: and (4) resource asynchronous loading function. The asynchronous resource loading function is a function that enables an applet to dynamically load resources as a user uses it during operation.

Step 603, in a third-party development tool, adapting a target function interface in the first application program, wherein the target function interface is a function interface which is not supported in the development tool of the sub-application program;

due to the difference between the third-party development tools and the development tools of the sub-applications, there are also some functional interfaces that are supported by the third-party development tools, but not by the sub-applications. Adaptation is required for the objective function interfaces specific to these third party development tools.

In an adaptive mode, deleting codes related to a target function interface; in another adaptation mode, an adaptation function interface matched with the target function interface is newly developed in the sub-application program.

It should be noted that step 602 and step 603 are optional steps.

Step 604, calling a resource export plug-in to search the art resources in the modified first application program, converting the searched art resources from the first resource format into a second resource format, and exporting the art resources in the second resource format to a development tool of the sub-application program;

optionally, the first resource format is a resource format supported in the Unity engine, and the second resource format is a resource format supported by a development tool of the sub-application.

The resource export plug-in is used for searching and traversing the art resource in the first application program after modification. Art resources include: scene resources, model resources, material resources, serialization attribute resources, building resources, game role resources, animation resources. The scene resources include: at least one of terrain resources, lake resources, tree resources, vegetation resources, light source resources, shadow resources, and static scenery resources.

And after calling the resource export plug-in to search out all the art resources, performing format conversion on each art resource, packaging all the art resources subjected to format conversion into a mgepackage format which can be identified by the sub-application platform, and importing the mgepackage format into a development tool of the sub-application.

Step 605, calling a code export plug-in to convert the C # code in the modified first application program into a JavaScript code, and exporting the JavaScript code to a development tool of the sub-application program;

the code export plug-in is used for exporting the C # code in the first application program after modification, and importing the exported C # code into a development tool of the sub-application program after converting the exported C # code into a JavaScript code.

Optionally, for the C # code in the modified first application, the code export plug-in can directly export the C # code.

Optionally, for a passive code plug-in (i.e. an external plug-in without C # code) in the modified first application, the code export plug-in generates stub code corresponding to the passive code plug-in. Stub code is Java script code that is used to replace a passive code plug-in.

606, performing secondary development on art resources and code resources in a development tool of the sub-application program to obtain a second application program;

optionally, a JS adapter plug-in is installed in the development tool of the sub-application. After the C # code is transplanted to the JavaScript code, the C # code cannot be completely run, and a bridge layer is needed. The JS adapter is the role of this bridging layer. JS adapters include, but are not limited to: bridging adaptation related to system capabilities, bridging adaptation related to performance tools, bridging adaptation related to math libraries.

The method comprises the following steps: and calling a JS adapter plug-in to bridge a C # interface supported by the C # code in the third-party development tool to a JS interface of the same type supported by the JavaScript script.

Optionally, a performance tool is installed in the development tool of the sub-application. The method also comprises the following steps: and calling a performance tool to perform performance optimization on the JavaScript code.

Step 607, the second application is tested.
