All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
For more detailed explanation of the present application, a method, an apparatus, a terminal device, and a computer storage medium for displaying a virtual gift in live broadcast provided by the present application are specifically described below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating an application scenario of a virtual gift presentation method in live broadcast provided by an embodiment of the present application, where the application scenario includes a server 102, a live broadcast end device 104, and a client device 106 provided by an embodiment of the present application. Wherein a network is arranged among the server 102, the live end device 104 and the client device 106. The network is used to provide a medium for communication links between the server 102, the live device 104, and the client device 106. The network may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few. The server 102 can communicate with the live device 104 and the client device 106 to provide live services for the live device 104 or/and the client device 106. For example, the live device 104 may send a live video stream of a live room to the server 102, and the user may access the server 102 through the client device 106 to view the live video of the live room. For another example, the server 102 may also send notification messages to the user's client device 106 when the user subscribes to a live room. The live video stream can be a video stream currently live in a live platform or a complete video stream formed after the live broadcast is completed.
In some implementation scenarios, the live device 104 and the client device 106 may be used interchangeably. For example, a anchor may use live end device 104 to provide live video services to viewers, as well as to view live video provided by other anchors as users. For another example, a user may use the client device 106 to view live video provided by a main cast of interest, or may serve live video as a main cast to other viewers.

The live device 104 and the client device 106 may have internet products installed therein for providing live internet services, for example, the internet products may be applications APP, Web pages, applets, and the like used in a computer or a smart phone and related to live internet services.
In the live broadcast, the audience user can interact with the main broadcast user, and a gift presenting function is often used in the interaction process, namely, the audience user presents the gift to the main broadcast user. The specific implementation process is as follows: the method comprises the steps that a spectator user sends a gift presentation request to a server through client equipment, the server obtains a corresponding virtual gift according to the gift presentation request of the spectator user, and the virtual gift is correspondingly issued to live broadcast end equipment of a main broadcast user and the client equipment of the spectator user so as to display the gift. The server acquires the corresponding gift and configures the corresponding display mode according to the request of the audience user.
It is understood that the application scenario shown in fig. 1 is only one possible example, and in other possible embodiments, the application scenario may include only some of the components shown in fig. 1 or may also include other components. For example, the application scenario shown in fig. 1 may further include a video capture terminal 108 for capturing a live video frame of the anchor, where the video capture terminal 108 may be directly installed or integrated in the live end device 104, or may be independent of the live end device 104, and the like, and this embodiment is not limited herein.
It should be understood that the number of live devices 104, client devices 106, networks, and servers 102 is merely illustrative. There may be any number of live devices 104, client devices 106, networks, and servers 102, as desired for an implementation. For example, the server may be a server cluster composed of a plurality of servers. The live device 104 and the client device 106 interact with the server through the network to receive or send messages and the like. The server 102 may be a server that provides various services. Wherein the live device 104 or the client device 102 may be configured to execute the live virtual gift display method provided in the embodiment of the present application. In addition, the server may also be configured to execute the method steps of displaying the interactive effect and the method steps other than the gift effect in the step of the live virtual gift display method provided in the embodiment of the present application. In addition, when the live device 104 or the client device 102 executes a live virtual gift presentation method provided in this embodiment of the application, a part of the steps may be executed in the live device 104 or the client device 102, and a part of the steps may be executed in a server, which is not limited herein.
Based on this, the embodiment of the application provides a virtual gift display method in live broadcasting. Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a method for displaying a virtual gift in live broadcast according to an embodiment of the present application, which is described by taking the method applied to the client device in fig. 1 as an example, and includes the following steps:
in step S110, when the transmission-type gift-giving instruction is detected, the movement trajectory of the transmission-type gift is acquired.
Specifically, an audience user can click to use a live broadcast application (for example, YY) installed on the client device, select to enter any one live broadcast room to watch live broadcast, and can give a virtual gift to a main broadcast in the process of watching live broadcast, at this time, a virtual gift interface needs to be opened, some virtual gifts can be displayed on the virtual gift interface, and the user can select a gift to be given to the main broadcast by clicking a virtual gift icon.
The virtual gifts may include, among other things, normal gifts and emissive gifts. The common gift is displayed at a specific position on a live broadcast interface after being given by a user, and only a virtual gift of a gift icon and a gift special effect can be displayed. The transmission type gift is a novel virtual gift configured by management personnel, the novel virtual gift can display the whole motion process on a live broadcast interface after being given by a user, namely, a gift icon starts from a starting point, moves to a destination along a motion track, and displays a special effect of the gift at the destination. For example, a rocket worth 0.1 wye may be configured by the manager as an emissive gift by the back office.
Alternatively, the client device may determine whether the virtual gift interface includes the transmission-type gift by traversing the virtual gift list, and may specifically determine by the type identifier on the virtual gift. The type identifier may be in various forms, such as a field or a graphic.
As shown in fig. 3, the manager configures the rocket as an emissive gift (a virtual gift marked by a dashed box in fig. 3), and marks two words of activity at the upper right corner of the rocket, wherein the activity is the type identifier of the emissive gift.
In addition, the transmission type gift generally includes a transmission mode identifier besides the type identifier, and the transmission mode identifier is used to indicate or explain the type of the transmission type gift movement track, such as straight line transmission, arc transmission (i.e. curve transmission) and the like.
When the user wants to give a virtual gift to the live broadcast, a gift-giving instruction is generated when the virtual gift icon is clicked. When the emissive gift icon is clicked, an emissive gift-giving instruction is generated, wherein the emissive gift-giving instruction generally includes identification information of the emissive gift and quantity information, the identification information is mainly used for determining which kind of the emissive gift is given by the user (i.e., determining the type of the emissive gift, such as hot air balloon or squash car), and the quantity information is used for determining the quantity of the emissive gift given by the user.
Further, the movement locus includes a straight movement locus and an arc movement locus (i.e., a curved movement locus). The movement locus may be formed in various ways. For example, the server may store a series of linear motion tracks and arc motion tracks configured by the manager in advance, and randomly acquire the motion tracks from the server when the user needs to give a gift of the transmission type. For example, the content may be selected from a library provided by a live program, or may be custom generated, but not limited thereto, by the viewer user. The setting of the motion track can be before the transmission type gift to be given is selected, or can be when the transmission type gift to be given is selected to be given. The motion trajectories of different transmission-type gifts may be the same or different.
Further, several embodiments of obtaining the motion track of the transmission type gift are given, and the following description is related to the following:
first embodiment mode:
referring to fig. 4, in an embodiment, the motion trajectory includes a linear motion trajectory, and in step S110, obtaining the motion trajectory of the transmission-type gift includes:
in step S112, the starting position, the launching angle, and the moving height or moving distance of the transmission type gift are acquired.
The starting position is the starting point of the transmission type gift movement, and the position is usually preset and can be any position in the screen of the client device. In actual live broadcast, for optimization of the effect display, the middle position of the bottommost end (i.e. the end farthest from the anchor image) of the client device is often selected as a starting point, for example, point a in fig. 5.
The launch angle refers to an angle formed by multiplying a straight line perpendicular to the horizontal direction in the vertical direction of the screen of the client device with the straight line motion track, wherein the start position is the start position, for example, θ in fig. 5.
The movement height refers to the distance length of the transmission type gift from the starting point to the end point in the vertical direction (i.e., vertical direction), such as h in fig. 5 (i.e., distance from a to a1 point, distance of right-angled side of triangle). Wherein, the value range of h is 0 to the maximum height value of the screen (the length value of the screen when the screen is vertical, and the width value of the screen when the screen is horizontal).
The movement distance is a distance length from the starting point to the ending point of the transmission type gift, for example, L in fig. 5, where L ranges from 0 to a screen diagonal length value.
The starting position, the launching angle, the moving height or the moving distance can be automatically input by the user through a mobile phone interface when giving the transmission type gift, and can also be selected according to parameter options provided by a live program. It may also be what the user collected by the sensor of the client device by rotating the client device (e.g., a cell phone) when giving away the transmission type gift.
In an optional implementation manner, the specific process of the sensor of the client device acquiring the starting position, the emission angle, and the movement height or the movement distance is as follows: after the user clicks the transmission type gift icon, the client device can start a self direction sensor, a guiding mode of user operation is displayed on a screen, and the user can tilt or rotate the mobile phone left and right according to the guiding mode, so that a transmitting angle, a movement height or a movement distance are formed. The guiding manner may be a guiding line showing a dashed line in the middle of the bottom of the client device, and the dashed line guiding line may be shifted left and right according to the inclination of the client device, so as to determine the transmitting direction (i.e., the transmitting angle).
For the direction sensor, it includes a direction angle, a side view angle and a bottom view angle. Where the azimuth angle (the angle of rotation about the z-axis). This is the angle between the current compass direction and the magnetic north of the client device. If the upper edge of the client device faces the north magnetic direction, the azimuth angle is 0 degree; if the upper edge is facing south, the azimuth is 180 degrees. Similarly, if the upper edge is east, the azimuth is 90 degrees; if the upper edge is facing west, the azimuth is 270 degrees.
Pitch angle (the angle of rotation about the x-axis). This is the angle between a plane parallel to the screen of the client device and a plane parallel to the ground. If the client device is placed parallel to the ground with its lower edge closest to the user, while the client device upper edge is tilted towards the ground, the pitch angle will become positive. Tilting in the opposite direction (moving the upper edge of the device away from the ground) will change the pitch angle to a negative value. The pitch angle ranges from-180 degrees to 180 degrees.
Roll angle (angle of rotation about the y-axis). This is the angle between a plane perpendicular to the screen of the client device and a plane perpendicular to the ground. If the client device is placed parallel to the floor with its lower edge closest to the user while the client device left edge is tilted toward the floor, the roll angle will become positive. Tilting in the opposite direction (moving the right edge of the device towards the ground) will bring the roll angle to a negative value. The roll angle has a value in the range of-90 degrees to 90 degrees.
It can be seen that the emission angle may be-180 to 270 degrees, but in practice, only-90 to 90 degrees are usually required to be obtained, but for the emission type gift display effect, the emission angle is usually-30 to 30 degrees.
In addition, when selecting the transmission angle by tilting the client device, the selection may be repeated for a certain time (usually set to a countdown time), based on the transmission angle selected at the last moment.
The emission height or the emission distance can be randomly generated within the value range, and specifically, a value can be randomly generated by adopting a random seed method.
And step S114, calculating the end position of the transmission type gift according to the transmission angle and the movement height or the transmission angle and the movement distance.
And step S116, forming a linear motion track according to the starting position and the end position.
And the terminal position of the transmission gift can be calculated after the transmission angle, the movement height or the movement distance is acquired. Alternatively, assuming the starting point is a, the a coordinate is (x)A，yA) The end point position is C, and the C coordinate is (x)C，yC) The launching angle is theta, the movement height is h, and the movement distance is L. Then, xC＝h.tanθ，yCH; or xC＝L.sinθ，yC＝L.cosθ。
And a linear motion track can be formed after the initial position and the final position are determined.
By adopting the method, the participation degree of the user in the motion track generation process can be increased, namely, the participation of the user in watching the gift presented in the live broadcast is increased, so that the interest of the live broadcast is improved.
Second embodiment mode:
in one embodiment, the motion trajectory includes a curved motion trajectory, and the obtaining of the motion trajectory of the transmission-type gift in the step S110 further includes:
acquiring the starting position, the launching angle and the moving height or the moving distance of the launching type gift; and calculating the end position of the transmission type gift according to the transmission angle and the movement height or the transmission angle and the movement distance. Randomly selecting a point out of the starting position and the end position, and recording the point as a middle position; and drawing a Bezier curve according to the starting position, the middle position and the end position to form a curve motion track.
The method for obtaining the starting position, the launching angle, the moving height or the moving distance of the transmission-type gift, and the method for calculating the ending position of the transmission-type gift refer to the related contents in the embodiments of steps S112 to S114, and are not described herein again.
In particular, on a straight-line basis, there are already two point coordinates, namely the starting position a (x)A，yA) End position C (x)C，yC) And then selecting a point to form a curve.

Third embodiment:
in one embodiment, in executing step S110, acquiring a motion trajectory of the transmission-type gift, further includes:
responding to the sliding path of the finger of the user on the screen or responding to the motion path of the space gesture of the user to form a motion track.
Specifically, the motion trajectory may also be formed according to a sliding path generated by a user sliding on a screen of the client device with a finger; or may be formed by a detected motion path of the user through an isolated gesture in a detection area (e.g., an infrared sensing area) of the client device.
