Example 1
Fig. 1A is a flowchart of a method for drawing a bullet screen according to an embodiment of the present disclosure, where the method may be applied to drawing bullet screen information in a video, and the method may be performed by a bullet screen drawing device according to an embodiment of the present disclosure, where the device may be implemented by software and/or hardware and integrated in an application program, and the method specifically includes the following steps:
s110, responding to the acquired barrage information to be displayed, and determining a matched target entity to be drawn according to the barrage type of the barrage information.
The bullet screen information may be classified into at least one of a variety of bullet screen types, for example, bullet screen information of plain text, bullet screen information with praise icons, bullet screen information with publisher head portraits and nicknames, etc., according to the presentation style of the bullet screen information. And the entity to be drawn (Draw Item) is a rendering carrier for carrying the barrage information, and after the barrage information is filled into the entity to be drawn, the entity to be drawn carrying the barrage information is rendered so as to display the barrage information in a screen, one entity to be drawn can only carry one barrage information at the same time, and meanwhile, the entity to be drawn also defines the display position and the display size of the barrage information in the screen.
Optionally, in an embodiment of the present disclosure, determining, according to a bullet screen type of bullet screen information, a matched target entity to be drawn includes: determining a corresponding entity type to be drawn according to the bullet screen type of the bullet screen information; selecting an idle entity to be drawn from the entity types to be drawn as a target entity to be drawn; each entity type to be drawn comprises at least one entity to be drawn, the number of the entities to be drawn, which are included in each entity type to be drawn, is positively correlated with the maximum display number of bullet screen types corresponding to each entity type to be drawn in a screen. For example, the entity type a to be drawn, the entity type B to be drawn and the entity type C to be drawn are respectively applicable to bullet screen information of pure characters, bullet screen information with praise icons and bullet screen information with publisher head portraits and nicknames, and the number of the entity types to be drawn included by each entity type to be drawn is related to the maximum display number of bullet screen types corresponding to each entity type to be drawn in a screen; taking the technical scheme as an example, comments posted by a common user scroll in the form of pure text barrage information, and 50 barrage information of the type can be displayed in a screen at most simultaneously, so that 50 entities to be drawn are also included in the entity type A matched with the barrage information of the type; comments posted by member users are all in the form of bullet screen information with a head portrait and a nickname of a publisher and at most 1 bullet screen information of the type can be displayed in the screen, so that only 1 entity to be drawn is needed in the entity type C matched with the bullet screen information of the type; in particular, the entities to be drawn in different entity types to be drawn are different. According to the correspondence between the bullet screen type and the entity type to be drawn, the entity to be drawn, which is matched with the bullet screen information, is determined, and the number of the entity to be drawn in the entity type to be drawn ensures that the bullet screen information of the type is displayed to the maximum extent in a screen, and resource waste caused by excessive number is avoided.
Optionally, in an embodiment of the present disclosure, after determining the corresponding entity type to be drawn, the method further includes: if no idle entity to be drawn exists in the corresponding entity type to be drawn, creating a new entity to be drawn in the entity type to be drawn, and taking the new entity to be drawn as a target entity to be drawn. Specifically, if the matched target entity to be drawn cannot be obtained according to the obtained barrage information, judging whether the corresponding entity type to be drawn can be obtained, if the corresponding entity type to be drawn cannot be obtained, adding the entity type to be drawn newly, and adding one entity to be drawn; if the corresponding entity type to be drawn can be obtained, adding a new entity to be drawn in the entity type to enable the entity to be drawn in the corresponding entity type to still meet the drawing requirement when the maximum display quantity of the barrage information in the screen is changed (for example, the display strategy of the barrage information is changed, five barrage information display lines in the screen are modified into six barrage information display lines, and correspondingly, the maximum display quantity of the barrage information in the screen is also changed); in particular, although the maximum display number of the barrage information in the screen becomes larger, new entities to be drawn are added, the number of the added entities to be drawn is still far smaller than that of the entities to be drawn used in the prior art, for example, a video includes 1000 barrage information, 1000 corresponding entities to be drawn are needed in the prior art, in this application, although the new entities to be drawn are added according to the maximum display number, the maximum display number of the barrage information in the screen is limited, for example, from 50 to 60, and accordingly, the number of the entities to be drawn also needs to be newly increased by 10, and the number of the newly increased entities to be drawn is also only 60, which is still far smaller than 1000 entities to be drawn used in the prior art.
Specifically, in response to obtaining a new entity type instruction to be drawn, creating a corresponding entity type to be drawn according to the new entity type instruction to be drawn, and adding at least one entity to be drawn in the created entity type to be drawn. And determining the number of the added entities to be drawn according to the data information contained in the new entity type instruction to be drawn, and if the new entity type instruction to be drawn does not comprise the specific addition number, adding one entity to be drawn by default.
S120, determining a target display layer matched with the barrage information, and transmitting the obtained barrage information and the target entity to be drawn to the target display layer, so that the target display layer performs typesetting processing on the target entity to be drawn according to the barrage information to obtain the typeset target entity to be drawn.
Optionally, in an embodiment of the present disclosure, the target presentation layer includes a rolling dynamic play presentation layer and/or a static play presentation layer; the dynamic play display layer displays the bullet screen information in a dynamic display mode, for example, displays the bullet screen information in a rolling play mode and displays the bullet screen information in a flashing play mode, wherein the dynamic play display layer can be divided according to the parameters such as the rolling direction, the rolling speed and the like. For example, the dynamic play presentation layer may include, but is not limited to, at least one of: a middle scroll display layer (located in the middle area of the screen) for scrolling bullet screen information from the left side to the right side of the screen or from the right side to the left side; and the oblique-end display layer is used for scrolling bullet screen information from the upper right corner of the screen to the lower left corner of the screen or from the upper left corner of the screen to the lower right corner of the screen. And the static playing display layer displays bullet screen information in a constant display mode. The static play presentation layer may also be divided according to the presentation position light parameters. For example, the static play presentation layer may include, but is not limited to, a top presentation layer and/or a bottom presentation layer. The top display layer and the bottom display layer can simultaneously display one piece of barrage information, and each barrage information disappears after being displayed for 5 seconds in a normal display mode. Through different types of show layers, can provide diversified visual effect for the barrage. It should be noted that, in the embodiment of the present disclosure, the above playing forms and positions are schematic, and do not constitute specific limitations on the playing forms of the target display layer and the positions of the target display layer in the screen.
Optionally, in an embodiment of the present disclosure, the typesetting processing is performed, by the target display layer, on a target entity to be drawn according to barrage information, including: the target display layer calculates the position information of the target entity to be drawn according to the content information of the barrage information; wherein, the content information of the barrage information comprises characters and/or images. The location information includes x-axis coordinates, y-axis coordinates, display width, and/or display height; the x-axis is the direction of entering bullet screen information horizontally and transversely in the screen, the y-axis is the direction perpendicular to the x-axis, and the origin is the upper left corner of the screen; the x-axis coordinate and the y-axis coordinate represent positions of the bullet screen information in the screen, and the display width and the display height represent display sizes of the bullet screen information; the display height of the bullet screen information is related to the height of the target display layer, and the display width is related to the length of the content information, for example, in order to ensure that as much comment information of a user as possible is displayed, the maximum display width is set to be 20 character lengths for each piece of comment information, when the comment information of the user is smaller than or equal to 20 character lengths, the display width is set according to the actual character lengths of the comment information, and when the comment information of the user is larger than 20 character lengths, the display width is set to be 20 character lengths. By setting the display area information, the display position of the bullet screen information is determined, and the phenomenon that the display of comment information of other users is influenced due to excessive content of one comment information is avoided on the premise of displaying the detailed comment information of the users. Particularly, if the target display layer is a dynamic play display layer, the target display layer calculates the position information of the target entity to be drawn according to the content information of the barrage information, including: the target display layer sets the stepping of the barrage information in the x-axis direction according to the content information of the barrage information. When the dynamic play display layer displays the bullet screen information in a rolling play mode, the position in the x-axis direction is not fixed, and besides the initial position, the stepping speed is required to be set so as to realize rolling play.
And S130, drawing the barrage information according to the typeset target entity to be drawn for display.
Optionally, in the embodiment of the present disclosure, drawing of bullet screen information may be implemented by Canvas; where Canvas is the container of interface components, specific drawing work is performed by creating a Canvas object and then invoking the Draw method.
Optionally, in an embodiment of the present disclosure, after drawing the barrage information according to the typeset target entity to be drawn, the method further includes: resetting the position information of the target entity to be drawn in response to the bullet screen information being displayed in the screen; and returning the reset target entity to be drawn to the corresponding entity type to be drawn as an idle entity to be drawn, and continuing to bear other barrage information so as to realize multiplexing of the entity to be drawn.
According to the technical scheme, the matched target to-be-drawn entity is determined according to the acquired bullet screen type of the bullet screen information to be displayed, typesetting processing is conducted through the target display layer, bullet screen information is drawn according to the typeset target to-be-drawn entity, new to-be-drawn entities are prevented from being created for each bullet screen information, separation of bullet screen information and to-be-drawn entities is achieved, technical support is provided for multiplexing of to-be-drawn entities, occupation of memory of terminal equipment is reduced, and drawing efficiency of the bullet screen information is improved.
