For convenience of understanding, a detailed flow of the embodiment of the present invention is described below, and referring to fig. 1, a first embodiment of a method for implementing a subtitle based on a ghost engine according to the embodiment of the present invention includes:

101. receiving first display content to be displayed through a function interface on a preset virtual caption display component, wherein the virtual caption display component is an object which is created based on a phantom engine and has a caption display function, and comprises a first-level caption, a second-level caption and a third-level caption;

it is to be understood that the execution subject of the present invention may be a caption implementing device based on a ghost engine, and may also be a terminal or a server, which is not limited herein. The embodiment of the present invention is described by taking a server as an execution subject.

In this embodiment, the first display content to be displayed is received through a function interface on a display component of a preset virtual caption, for example, "when actual hoisting is performed, the number of hoisting personnel needs to be determined according to the actual weight of equipment, and it is generally recommended to add one hoisting personnel every time 20KG is added" long sentence display:

"in actual hoisting, the actual weight of the equipment is determined

The number of hoisting personnel is generally recommended to be increased by 20KG every time

Adding one lifting worker "

The virtual caption display component is created according to the illusion engine, and is a component that can display captions, which is an object (Actor), and exists in the virtual world in reality.

The illusion engine writes code using C + +, has high portability, is a tool used by many game developers today, and focuses on data generation and program writing. Not only is a hall-level game engine, but also can bring unlimited creation freedom and unprecedented control for professionals in all walks of life. Whether it is a frontier content, interactive experience, or immersive virtual world, everything is in the illusion engine.

In this embodiment, the subtitles include a primary subtitle, a secondary subtitle, and a tertiary subtitle. The three-level subtitles also comprise a single-line three-level subtitle and a double-line three-level subtitle; both the first level subtitle and the second level subtitle contain only one scroll box (ScrollBox), and both the single line of the third level subtitle and the double line of the third level subtitle contain only one multilineue editable text box (multilineeeditabetbox). In design, the single-line three-level subtitles can only store one line of contents; the double-row three-level subtitles can store two rows of contents; the second-level subtitles are used for storing single-line third-level subtitles or double-line third-level subtitles; the primary captions are used to store the secondary captions.

102. Inputting the first display content into a first-level caption, creating a second-level caption based on the first-level caption, synchronizing the first display content to the second-level caption and adding the second-level caption to a scroll of the first-level caption;

in this embodiment, the first display content may refer to text content of all subtitles to be displayed received within a time period, or may refer to text content of all subtitles to be displayed received at a time point.

Creating a primary caption, and creating n secondary captions according to the current primary caption when receiving the text contents of n captions to be displayed in a time period; when receiving text contents of 1 subtitle to be displayed within a period of time, 1 secondary subtitle should be created according to the current primary subtitle. And further, according to the specific line number of the text content of the caption and the corresponding caption display rule, creating a corresponding three-level caption. Wherein the three-level subtitles include a single line of three-level subtitles and a double line of three-level subtitles. It should be noted that, when at least 2 secondary subtitles exist in the scroll of one primary subtitle, the subtitles are scrolled and played; when at least two single-line three-level subtitles exist in one two-level subtitle, the subtitles are played in a rolling mode. In other cases, the subtitles are displayed still and do not scroll.

In this embodiment, the primary subtitle takes charge of the overall control, and the primary subtitle is to be switched to a different secondary subtitle in a rolling manner whenever a new secondary subtitle is to be added to the primary subtitle.

103. Synchronizing the first display content to the second-level caption, cutting the first display content according to a preset caption display rule to generate at least one third-level caption, and adding the at least one third-level caption to a rolling block of the second-level caption, wherein the third-level caption comprises a single-line third-level caption and a double-line third-level caption;

in this embodiment, the first display content is synchronized from the primary subtitle to the secondary subtitle added to the scroll of the primary subtitle, and at least one tertiary subtitle is asserted according to a preset subtitle display rule. At this time, whether the first display content needs to be cut or not is mainly related to the specific text content and the subtitle display rule of the first display content. For example, if the first display content is "actually hoisting, the number of hoisting personnel needs to be determined according to the actual weight of the equipment", and if the caption display rule is "only one line can display no more than 15 words", the first display content needs to be cut; if the subtitle display rule is "one line can only display no more than 30 words", no cutting of the first display content is required.

Further, at least one tertiary subtitle is generated, and the (at least one) tertiary subtitle is added to the scroll box of the secondary subtitle. The second-level subtitles are responsible for local control, and each time different third-level subtitles (including single-line third-level subtitles and double-line third-level subtitles) are added into the (rolling blocks) of the second-level subtitles, the second-level subtitles are rolled and switched to different single-line third-level subtitles or double-line third-level subtitles.

Because the preset caption display rule, such as "the caption box can only accommodate 2 lines of characters at most", and the caption content to be input is flexible, there are two cases:

1. when the input first display content can be completely displayed within two lines, the subtitle (first display content) does not need to be scrolled at the moment;

2. if the input first display content exceeds two lines, three or four lines can be displayed completely; at this time, the analysis is specifically performed according to the specific situation.

104. And controlling at least one three-level caption to be displayed based on the first scrolling parameter of the scrolling block of the first-level caption and the second scrolling parameter of the second-level caption so as to realize the sequential playing of the first display content.

In this embodiment, according to the first scroll parameter of the scroll of the primary subtitle and the second scroll parameter of the scroll of the secondary subtitle, the (at least one) tertiary subtitle is controlled to be displayed, and the first display content is played. For example, the subtitle box can only accommodate two lines of display content at most, and when the input subtitles can be completely displayed within two lines, the double-line three-level subtitles are called (the double-line three-level subtitles can store the content within two lines); when the input caption (display content) exceeds two lines, the secondary caption can 'cut' the first display content input into the caption box into n lines of content, and then put the n contents into the corresponding n single lines of tertiary caption respectively; at this time, the scrolling parameter of the second-level caption calls for storing the single-line(s) of the third-level caption and scrolls and plays the display contents.

In the embodiment of the invention, a function interface on a preset virtual caption display component is used for receiving first display content to be displayed and inputting the first display content into a first-level caption; creating a secondary subtitle according to the primary subtitle, and synchronizing the first display content to the secondary subtitle; cutting the first display content through the secondary subtitles, and respectively inputting the cut display content into at least one tertiary subtitle created according to the secondary subtitles; and inputting the obtained three-level subtitles into the rolling block of the two-level subtitles, and controlling at least one three-level subtitle to display based on the first rolling parameter of the rolling block of the one-level subtitles and the second rolling parameter of the two-level subtitles so as to realize the sequential playing of the first display content. The subtitle function can be provided for the virtual application, and the subtitle exists in the virtual world in reality.

Referring to fig. 2, a second embodiment of the method for implementing a subtitle based on a ghost engine according to an embodiment of the present invention includes:

201. receiving first display content to be displayed through a function interface on a preset virtual caption display component, wherein the virtual caption display component is an object which is created based on a phantom engine and has a caption display function, and comprises a first-level caption, a second-level caption and a third-level caption;

202. inputting the first display content into a first-level caption, creating a second-level caption based on the first-level caption, synchronizing the first display content to the second-level caption and adding the second-level caption to a scroll of the first-level caption;

203. analyzing the first display content to obtain the total line number of the first display content, and judging whether the total line number is greater than a preset line number threshold value;

in this embodiment, the first display content is analyzed, and whether the first display content needs to be cut is determined according to an analysis result and a preset subtitle display rule.

The caption display rule is preset in the program, for example, the text content that the caption box can be displayed at most in 2 lines each time in the program, if the content to be displayed exceeds two lines, the content to be displayed needs to be cut, and then the next three-level caption creation and display can be performed; if the subtitle to be displayed does not exceed 2 lines, the content to be displayed does not need to be cut. Meanwhile, the number of the lines of the content to be displayed corresponds to different three-level subtitles.

204. Calculating the total number of bytes of the first display content;

in this embodiment, since the number of bytes corresponding to each character in the text is different from the number of bytes corresponding to each letter in the english, after the content to be displayed is analyzed and determined, the number of bytes of the content to be displayed needs to be calculated more exactly, and the content to be displayed is specifically cut according to the number of bytes of the content to be displayed.

Bytes (Byte) is a unit of measure used by computer information technology to measure storage capacity, and also represents data types and language characters in some computer programming languages. One bit section stores 8-bit unsigned numbers, with values in the range of 0-255. As with a word, a byte-wise variable needs to be stored in only one byte (8 bits) of memory space.

205. Judging whether the total byte number exceeds a first byte threshold value or not;

the caption display rule is preset in the program, for example, the text content that the caption box can be displayed at most in 2 lines each time in the program, if the content to be displayed exceeds two lines, the content to be displayed needs to be cut, and then the next three-level caption creation and display can be performed; if the subtitle to be displayed does not exceed 2 lines, the content to be displayed does not need to be cut. Meanwhile, the number of the lines of the content to be displayed corresponds to different three-level subtitles. However, specifically for the display content of each line, different programs correspond to different display rules, for example, the maximum displayable text content of the subtitle box in the program is 2 lines, but the maximum value of the number of bytes that can be accommodated by each line is preset, for example, 72 bytes, and the specific cutting processing needs to be performed on the display content according to the specific number of bytes of the display content, so that it is necessary to first determine whether the total number of bytes of the display content exceeds the first byte threshold value at this time.

206. If the total byte number does not exceed the first byte threshold value, creating a double-row three-level caption based on the two-level caption, and inputting the first display content into the double-row three-level caption through a preset function interface of the double-row three-level caption; adding the tertiary subtitles to the scroll of the secondary subtitles;

in this embodiment, if the total number of bytes of the content to be displayed does not exceed the maximum number of bytes preset by the program, the caption frame can accommodate the content to be displayed, and at this time, a double-row three-level caption can display the content to be displayed, and at this time, a double-row three-level caption is created directly according to the created two-level caption; and inputting the content to be displayed into the double-line three-level subtitles through a preset function interface of the double-line three-level subtitles, and adding the double-line three-level subtitles into a rolling block of the two-level subtitles.

207. If the total byte number exceeds a first byte threshold value, creating at least two single-line three-level subtitles based on the two-level subtitles, and respectively inputting the first display content into the at least two single-line three-level subtitles through a preset function interface of the single-line three-level subtitles; adding at least two single-line tertiary subtitles to a scroll of the secondary subtitles;

in this embodiment, if the total number of bytes of the content to be displayed exceeds the maximum number of bytes preset by the program, it is indicated that the subtitle box cannot accommodate the content to be displayed, at this time, a plurality of single-line three-level subtitles need to be created, the content to be displayed is cut, the cut content to be displayed is respectively input to the corresponding single-line three-level subtitles, the content to be displayed is input to the double-line three-level subtitles through a function interface preset by the single-line three-level subtitles, and the double-line three-level subtitles are added to the rolling blocks of the two-level subtitles.

The function interface is also called an interface function, which means that a certain module writes a function (mainly) for other modules. Simply speaking, an interface function is a common function in a class. For example: SendMessage (.): is a messaging function, we do not need to know how it is implemented, only need to know that he can implement sending a message to something. This is the interface, and the interface is the implementation correspondingly.

208. If the total line number is smaller than a preset line number threshold, creating a three-level subtitle with a subtitle display line number being the preset line number threshold, inputting the first display content into the three-level subtitle with the subtitle display line number being the preset line number threshold, and adding the three-level subtitle with the preset line number threshold into a rolling block of the two-level subtitle;

in this embodiment, if the total number of rows of the content to be displayed is less than the threshold of the preset number of rows, for example, when the content to be displayed is "actual hoisting," it is necessary to determine that the number of hoisting personnel "does not exceed 2 rows according to the actual weight of the device, at this time, only one double-row three-level subtitle needs to be created, and the text content (first display content) is received through the preset function interface, and the created three-level subtitle is added to the scroll block of the two-level subtitle.

The scroll box is a scrollable UI component to which content is added with a node display list (AddChild); the position to which to scroll is set with the set control offset (SetScrollOffset).

The secondary caption comprises a tertiary caption (double lines) or more than two tertiary captions (single lines); each level of caption contains a function interface (SetMyText) to receive the text content; the primary subtitle and the secondary subtitle each contain a scroll box (ScrollBox); the triple-level subtitles all contain a multi-line editable text box (multilinededataboxbox). And the three-level caption (single line or double lines) receives the text content (first display content) through a preset function interface, judges whether the text content exceeds two lines, cuts the text content if the text content exceeds two lines, plays the rolling animation, and adds the cut (displayed) text content into the rolling block again after the text content rolls to the bottom so as to continue rolling.

209. And controlling at least one three-level caption to be displayed based on the first scrolling parameter of the scrolling block of the first-level caption and the second scrolling parameter of the second-level caption so as to realize the sequential playing of the first display content.

The

steps

201, 202, 209 in this embodiment are similar to the

steps

101, 102, 104 in the first embodiment, and are not described here again.

Referring to fig. 3, a third embodiment of the method for implementing subtitles based on a ghost engine according to the embodiment of the present invention includes:

301. receiving first display content to be displayed through a function interface on a preset virtual caption display component, wherein the virtual caption display component is an object which is created based on a phantom engine and has a caption display function, and comprises a first-level caption, a second-level caption and a third-level caption;

302. inputting the first display content into a first-level caption, creating a second-level caption based on the first-level caption, and adding the second-level caption into a rolling block of the first-level caption;

303. creating an array based on the secondary caption, and storing the first display content into the array to obtain a second display content;

in this embodiment, an array is created for storing the display content based on the secondary subtitle, and the first display content is renamed. For example, when the first display content is "actually hoisting, the hoisting number needs to be determined according to the actual weight of the equipment," generally, 20KG is added for each increase of the first display content "is input into the created array, at this time, the first display content is named as" second display content, "then, the second display content is" when the actual hoisting is performed, the hoisting number needs to be determined according to the actual weight of the equipment, generally, 20KG is added for each increase of the second display content, "at this time, whether the input second display content exceeds 36 bytes is judged. And further, carrying out the next operation according to the judgment result.

The Array (Array) is an ordered sequence of elements. If a set of a finite number of variables of the same type is named, then this name is the array name. The individual variables that make up an array are referred to as the components of the array, also referred to as the elements of the array, and sometimes as subscript variables. The numerical numbering used to distinguish the various elements of the array is referred to as the subscript. An array is a form in which elements of the same type are organized in an ordered fashion for processing convenience in programming. The collection of these ordered homogeneous data elements is called an array. An array is a collection for storing multiple data of the same type. An array may be decomposed into a plurality of array elements, which may be of either primitive data type or construct type. Therefore, the array can be divided into various categories such as numerical array, character array, pointer array, and structure array according to the type of the array elements.

respectively creating a single-line three-level caption for each display content according to the n display contents cut by the second display content; because a single line of three-level subtitles can just store one display content (byte number less than or equal to 36 bytes). At this time, one display content is corresponded to one single line of three-level subtitles.

And respectively adding the n display contents into the rolling blocks of the secondary subtitles through the preset function interfaces of the three-level subtitles of a single line, wherein the n display contents obtained by cutting are not more than the preset maximum threshold value in number of bytes. For example, the second display content "in actual hoisting, the hoisting number needs to be determined according to the actual weight of the equipment," generally, 20KG is added every time a hoisting person is added, "in actual hoisting, the hoisting number needs to be determined according to the actual weight of the equipment," in third display content, "in actual hoisting, the hoisting number needs to be determined according to the actual weight of the equipment," in fourth display content, "20 KG is added every time a hoisting person is added," and "in fifth display content" a hoisting person is added "; at the moment, n is 3, corresponding to the three-level subtitles of 3 single lines, and inputting the third display content, the fourth display content and the fifth display content into the corresponding three-level subtitles of each single line through a preset function interface corresponding to the three-level subtitles of each single line; and adding the three-level subtitles carrying a single line of the display content to the scroll box of the local two-level subtitles.
