Description

Technical Field

[0001] This specification relates to the field of Unreal Engine technology, and in particular to a method, device, and apparatus for setting and displaying pages based on Unreal Engine. Background Art

[0002] As society develops, people's demands for on-screen page rendering performance are becoming increasingly stringent. To achieve increasingly refined display effects, Unreal Engine and browser applications can be used to collaboratively display pages. This means that the displayed page contains both portions of the page generated by the Unreal Engine and those generated by the browser application, combining the two to achieve a more refined display effect. However, how to enable interactive communication between the Unreal Engine and browser applications, so that the portions of the page generated by the Unreal Engine and the browser application within the same page can respond to each other, remains a technical challenge.

[0003] The existing technology uses WebSocket, a protocol for full-duplex communication (full-duplex means both parties can send messages to each other simultaneously) over a single TCP connection. WebSocket establishes a dedicated communication service, where the browser application sends interactive information to the server, which then forwards it to the Unreal Engine. Upon receiving the interactive information, the Unreal Engine performs the corresponding operation, and vice versa, thus completing the information exchange. However, this interactive communication method has a long communication link, frequent network communications, and is server-dependent. If the server fails, the interactive communication between the Unreal Engine and the browser application will completely fail. Summary of the Invention

[0048] To make the purpose, technical solutions, and advantages of one or more embodiments of this specification more clear, the technical solutions of one or more embodiments of this specification will be clearly and completely described below in conjunction with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of one or more embodiments of this specification.

[0049] The technical solutions provided by the embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0050] In the existing technology, a service dedicated to communication is built through WebSocket to realize interactive communication between the Unreal Engine and the browser application, so that the part of the page generated by the Unreal Engine and the part of the page generated by the browser application in the same page can respond to each other. However, the communication link of this interactive communication method is long, the network communication is frequent, and it relies on the server. If there is a problem with the server, the interactive communication between the Unreal Engine and the browser application will completely fail.

[0051] In order to solve the defects in the prior art, this solution provides the following embodiments:

[0052] Figure 1 This is a flow chart of a page setting method based on Unreal Engine provided in the embodiment of this specification. Figure 1As shown, the process may include the following steps:

[0053] Step 102: Obtain the user's trigger operation on the user interface blueprint built into the Unreal Engine.

[0054] In the embodiments of this specification, the user interface blueprint is the UI blueprint built into the Unreal Engine. The so-called blueprint is a visual script that can provide designers with all the concepts and tools that are generally only used by programmers. Programmers can easily create a basic system and hand it over to the planner to further expand such a system in the blueprint.

[0055] In the embodiments of this specification, the Unreal Engine may specifically be UE4, the user may be a software developer, and the user's triggering operation on the user interface blueprint built into the Unreal Engine may be a click operation or an instruction-based triggering operation, which is not specifically limited.

[0056] Based on this, step 102: obtaining the user's triggering operation for the user interface blueprint built into the Unreal Engine may specifically include:

[0057] Get the user's trigger action on the UE4 built-in user interface blueprint.

[0058] In the examples of this specification, UE4 stands for Unreal Engine 4, which translates to "Unreal Engine 4" in Chinese. UE4 is an open-source game engine developed by Epic Games. UE4 utilizes the latest technologies, including real-time ray tracing, HDR lighting, and virtual displacement. It can also process 200 million polygons per second in real time, enabling the creation of cinematic CG-quality graphics with exceptional performance.

[0059] Step 104: In response to the trigger operation, a predefined WebBrowser class is created at the Unreal Engine for displaying a target application page; the target application page includes a page generated based on the Unreal Engine and displayed in a first preset area and a page generated based on the browser application and displayed in a second preset area; the Unreal Engine is configured to generate a first page to be displayed at the first preset area according to the event information of the first call event after a first event listening task created by the predefined WebBrowser class listens to a first call event of the browser application for a first preset function at the Unreal Engine; the browser application is configured to generate a second page to be displayed at the second preset area according to the event information of the second call event after a second event listening task created by the predefined WebBrowser class listens to a second call event of the Unreal Engine for a second preset function at the browser application.

[0060] In the embodiments of this specification, the WebBrowser class is a plugin class for browsing pages that comes with Unreal Engine (UE4). A WebBrowser class can be created within the Unreal Engine's user interface blueprint to display a target application page. This WebBrowser class is predefined by writing a communication script into its graph. This predefined WebBrowser class can create a first event listening task to listen for a first call event from the browser application to a first preset function in the Unreal Engine, and can also create a second event listening task to listen for a second call event from the Unreal Engine to a second preset function in the browser application.

[0061] Based on this, step 104: in response to the triggering operation, a predefined WebBrowser class is created in the Unreal Engine for displaying the target application page, which may specifically include:

[0062] In response to the triggering operation, a predefined WebBrowser class for displaying a target application page is created at the UE4.

[0063] Correspondingly, after creating a predefined WebBrowser class for displaying the target application page at the UE4, the following steps may also be included:

[0064] A target installation file is generated according to the first installation file of the UE4 carrying the predefined WebBrowser class and the second installation file of the browser application; the target installation file is used to display the target application page when running at the terminal device.

[0065] In the embodiments of this specification, the first installation file is the installation file obtained by a developer after developing UE4. Running the first installation file enables the corresponding UE4 to be run. The second installation file is the installation file obtained by a developer after developing a browser application. Running the second installation file enables the corresponding browser application to be run. Generating the target installation file based on the first installation file for UE4 carrying a predefined WebBrowser class and the second installation file for the browser application may involve packaging the first and second installation files or reassembling them, without specific limitation.

[0066] Figure 2 This is a flow chart of a method for displaying a page based on Unreal Engine provided in the embodiment of this specification. Figure 2 As shown, the process may include the following steps:

[0067] Step 202: The terminal device obtains a user trigger operation for a target application page; the target application page includes a page generated based on the Unreal Engine and displayed in a first preset area and a page generated based on the browser application and displayed in a second preset area.

[0068] In the embodiments of this specification, the terminal device can be a computer or a mobile phone, and there is no specific limitation on this. The user's triggering operation on the target application page can be a mouse click operation or a user's touch screen operation, and there is no specific limitation on this.

[0069] In an embodiment of the present specification, a target application page can be presented on a screen of a terminal device. The target application page can include a page generated based on the Unreal Engine and displayed in a first preset area, and a page generated based on a browser application and displayed in a second preset area. The first preset area and the second preset area are located in different locations and have no common area. The specific locations of the first preset area and the second preset area in the target application page are not specifically limited. For example, the first preset area can be on the left side of the target application page and the second preset area can be on the right side of the target application page. Alternatively, the first preset area can be on the upper side of the target application page and the second preset area can be on the lower side of the target application page.

[0070] In the embodiment of this specification, the terminal device needs to start the Unreal Engine and the browser application before obtaining the user's triggering operation on the target application page.

[0071] Based on this, step 202: before the terminal device obtains the user's triggering operation on the target application page, the following may also be included:

[0072] The terminal device obtains a target installation file; the target installation file is generated according to a first installation file of the Unreal Engine carrying the predefined WebBrowser class and a second installation file of the browser application.

[0073] The terminal device starts the Unreal Engine and the browser application based on the target installation file.

[0074] Step 204: Determine the target event triggered by the triggering operation by utilizing the first event monitoring task at the Unreal Engine and the second event monitoring task at the browser application created by the predefined WebBrowser class in the Unreal Engine.

[0075] In the embodiment of this specification, it is necessary to judge the monitoring results of the first event monitoring task and the second event monitoring task, and determine the target event triggered by the user's triggering operation on the target application page according to the judgment result.

[0076] Based on this, step 204: using the first event monitoring task at the Unreal Engine and the second event monitoring task at the browser application created by the predefined WebBrowser class in the Unreal Engine to determine the target event triggered by the triggering operation may specifically include:

[0077] It is determined whether the first event monitoring task monitors a call event of the browser application to a first preset function at the Unreal Engine, and a first determination result is obtained.

[0078] If the first judgment result indicates that the first event monitoring task monitors the call event of the browser application for the first preset function at the Unreal Engine, it is determined that the triggering operation triggers a target event for displaying the page at the first preset area.

[0079] If the first judgment result indicates that the first event monitoring task did not monitor the call event of the browser application for the first preset function at the Unreal Engine, then it is determined whether the second event monitoring task monitors the call event of the Unreal Engine for the second preset function at the browser application to obtain a second judgment result.

[0080] If the second judgment result indicates that the second event monitoring task monitors the call event of the Unreal Engine for the second preset function at the browser application, it is determined that the trigger operation triggers the target event for displaying the page at the second preset area.

[0081] In actual applications, this solution can be used for vehicle-road collaborative operations. Correspondingly, the target application page generated based on the Unreal Engine and displayed in the first preset area can present different driving perspectives, and the target application page generated based on the browser application and displayed in the second preset area can present the driving perspective selection page and the vehicle information of the selected vehicle. In this case, the first event monitoring task at the Unreal Engine created using the predefined WebBrowser class in the Unreal Engine can be a monitoring task for the user's selection operation of the driving perspective on the page in the second preset area, and correspondingly, the second event monitoring task at the browser application can be a monitoring task for the user's selection operation of the vehicle on the page in the first preset area.

[0082] Step 206: If the target event is a call event of the browser application for a first preset function at the Unreal Engine monitored by the first event monitoring task, the Unreal Engine is used to generate a first page to be displayed at the first preset area according to the event information of the target event; if the target event is a call event of the Unreal Engine for a second preset function at the browser application monitored by the second event monitoring task, the browser application is used to generate a second page to be displayed at the second preset area according to the event information of the target event.

[0083] In the embodiment of this specification, the first page to be displayed in the first preset area is generated by the Unreal Engine.

[0084] Before the web page or browser application generates the second page to be displayed in the second preset area, it is also necessary to judge the function return value after the preset function is called.

[0085] Based on this, step 206 may specifically include:

[0086] If the target event is a call event of the browser application for the first preset function at the Unreal Engine monitored by the first event monitoring task, a first preset function return value after the first preset function is called is obtained.

[0087] 0 Determine whether the return value of the first preset function is the first preset value; if so, allow the virtual

[0088] The engine generates a first page to be displayed in the first preset area.

[0089] If the target event is a call event of the Unreal Engine for a second preset function at the browser application monitored by the second event monitoring task, a second preset function return value after the second preset function is called is obtained.

[0090] 5. Determine whether the return value of the second preset function is a second preset value; if so, allow the browser application to generate a second page to be displayed in the second preset area.

[0091] In actual application, corresponding to the scenario described above where this solution is used for vehicle-road cooperative operation, the target application page generated based on the Unreal Engine and displayed in the first preset area can present different driving perspectives, and the target application page generated based on the browser application and displayed in the second preset area can present the driving perspective selection page and the vehicle information of the selected vehicle.

[0092] The selection of driving perspective in the area page corresponds to the call event of the first preset function in the Unreal Engine. The return value after the user selects "first-person driving perspective" is called.

[0093] "1", when it is determined that the return value of the first preset function is the first preset value (1), the phantom call is allowed.

[0094] The engine generates a first page to be displayed in the first preset area (the first page to be displayed displays a picture of the first-person 5 driving perspective); if the user's selection operation of the vehicle in the page of the first preset area corresponds to a call event of the second preset function in the browser application, the user selects the vehicle numbered "2", and the return value after the corresponding second preset function is called is "2", then when it is judged that the return value of the second preset function is the second preset value (2), the browser application is allowed to generate a second page to be displayed in the second preset area (the second page to be displayed displays the vehicle information of the vehicle numbered 2).

[0095] Step 208: Display the first page to be displayed or the second page to be displayed in the target application page.

[0096] In an embodiment of the present specification, the first page to be displayed generated by the Unreal Engine is displayed at the first preset area in the target application page, the second page to be displayed generated by the browser application is displayed at the second preset area in the target application page, and the entire target application page is displayed on the screen of the user terminal device.

[0097] Figure 1 Combining the methods in Figure 2 The method described herein develops a WebBrowser class in Unreal Engine for displaying target application pages, and utilizes this WebBrowser class to enable interaction between the Unreal Engine-generated portion of the target application page and the browser-generated portion. Based on the present invention, when the Unreal Engine and the browser application collaborate to display pages, their interactive communication no longer relies on external services. Furthermore, this solution not only facilitates the maintenance of communication logic but also eliminates network latency, enabling faster interaction between the Unreal Engine-generated portion and the browser-generated portion of the same page.

[0133] In response to the trigger operation, a predefined WebBrowser class is created at the Unreal Engine for displaying a target application page; the target application page includes a page generated based on the Unreal Engine and displayed in a first preset area and a page generated based on the browser application and displayed in a second preset area; the Unreal Engine is configured to generate a first page to be displayed in the first preset area according to the event information of the first call event after a first event listening task created by the predefined WebBrowser class listens to a first call event of the browser application for a first preset function at the Unreal Engine; the browser application is configured to generate a second page to be displayed in the second preset area according to the event information of the second call event after a second event listening task created by the predefined WebBrowser class listens to a second call event of the Unreal Engine for a second preset function at the browser application.

[0134] Figure 6 The embodiments of this specification provide corresponding Figure 2 A schematic diagram of the structure of a page display device based on Unreal Engine. Figure 6 As shown, the device 600 may include:

[0135] at least one processor 610; and,

[0136] A memory 630 in communication with the at least one processor; wherein,

[0137] The memory 630 stores instructions 620 that can be executed by the at least one processor 610. The instructions are executed by the at least one processor 610 to enable the at least one processor 610 to:

[0138] Acquire a user's triggering operation for a target application page; the target application page includes a page generated based on an Unreal Engine and displayed in a first preset area and a page generated based on a browser application and displayed in a second preset area.

[0139] A target event triggered by the triggering operation is determined by utilizing a first event monitoring task at the Unreal Engine and a second event monitoring task at the browser application created by a predefined WebBrowser class in the Unreal Engine.

[0140] If the target event is a call event of the browser application for a first preset function at the Unreal Engine monitored by the first event monitoring task, the Unreal Engine is used to generate a first page to be displayed at the first preset area according to the event information of the target event.

[0141] If the target event is a call event of the Unreal Engine for a second preset function at the browser application monitored by the second event monitoring task, the browser application is used to generate a second page to be displayed at the second preset area according to the event information of the target event.

[0142] The first page to be displayed or the second page to be displayed is displayed in the target application page.

[0143] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments. Figure 5 and Figure 6 As for the device shown, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0144] In the 1990s, technological improvements could be clearly distinguished as either hardware improvements (for example, improvements to circuit structures like diodes, transistors, and switches) or software improvements (improvements to process flows). However, with the advancement of technology, many process flow improvements today can now be considered direct improvements to hardware circuit structures. Designers almost always create the corresponding hardware circuit structure by programming the improved process flow into the hardware circuit. Therefore, it cannot be said that a process flow improvement cannot be implemented using hardware modules. For example, a programmable logic device (PLD), such as a field programmable gate array (FPGA), is an integrated circuit whose logical function is determined by user programming. Designers can "integrate" a digital system on a PLD through their own programming, without having to hire a chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly done using "logic compiler" software. This is similar to the software compiler used when developing programs. Before compilation, the original code must also be written in a specific programming language, called a hardware description language (HDL). There is not just one HDL, but many, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art will also understand that by simply programming the method flow in one of these hardware description languages ​​and then programming it into an integrated circuit, a hardware circuit that implements the logic method flow can be easily obtained.

[0145] The controller can be implemented in any suitable manner. For example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of controllers include, but are not limited to, the following microcontrollers: ARC625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also know that in addition to implementing the controller in a purely computer-readable program code manner, it is entirely possible to implement the same functionality in the form of logic gates, switches, an application-specific integrated circuit, a programmable logic controller, and an embedded microcontroller by logically programming the method steps. Therefore, such a controller can be considered a hardware component, and the means for implementing various functions included therein can also be considered as structures within the hardware component. Or even, the means for implementing various functions can be considered as both a software module implementing the method and a structure within the hardware component.

[0146] The systems, devices, modules, or units described in the above embodiments may be implemented by computer chips or entities, or by products having certain functions. A typical implementation device is a computer.

As defined herein, computer-readable media does not include transitory computer-readable media (transitory media), such as modulated data signals and carrier waves.
