FIG. 7 is a flow chart of a method for holding a virtual object provided by one or more embodiments of the present disclosure. The method is applied to an electronic device, and the electronic device includes but is not limited to an XR device, a mobile phone, a computer, a wearable device, etc. As shown in FIG. 7, the method provided by the present embodiment includes the following steps.

S101. Displaying a combined virtual object. The combined virtual object includes a plurality of sub-virtual objects, the combined virtual object is configured with a combined holding parameter, and at least one sub-virtual object in the combined virtual object is configured with a sub-holding parameter, respectively.

The combined virtual object can be a virtual prop. In the game scene, the virtual prop is also called a game prop, and the combined virtual object can be called a combined prop.

The combined virtual object can be displayed in the virtual scene or in the user's backpack. After the user opens the backpack, the combined virtual object is displayed in the backpack.

In the game scene, the backpack refers to a storage space (also called a storage bar) on the game role (avatar). In the game scene, a certain number of storage bars will be set on the avatar, so that the avatar can place game equipment and game props, meanwhile the backpack will also display the amount of virtual currency owned by the avatar.

The virtual scene can be a scene provided by the client itself or a scene defined by the user. Taking an XR device as an example, in order to meet the personalized needs of the user, UGC function is added, that is, the user can customize a virtual scene in the editor provided by the game according to his/her own needs, and the virtual scene customized by the user is also called the user's own world, and other users can enter the virtual scene customized by the user to play.

The editor can provide some editing elements, such as polyhedra, controls, materials, physics, logic, music, sound effects, special effects and source material, etc., for the user to use. The user can not only customize the virtual scene in the editor, but also customize props. The props customized by the user can be called UGC props. Similarly, the virtual scene customized by the user can be called a UGC world or a UGC scene. Customization in the embodiment of the present disclosure can be understood as that the an object or scene formed by the user's self-construction in the editor by using the editing elements provided by the editor.

In the virtual scene, there are not only combined virtual objects, but also independent virtual objects. The independent virtual object is relative to the combined virtual object, the combined virtual object refers to a virtual object composed of a plurality of sub-virtual objects, and each sub-virtual object is an independent virtual object.

The meaning of “composed of” here can be understood as that when the combined virtual object is released, the plurality of sub-virtual objects composing the combined virtual object are released as a whole. For example, basketball and basketball hoop can be independent virtual objects, or they can be released as a whole as a combined virtual object. For the combined virtual object, the combined virtual object can be held as a whole, or the sub-virtual objects in the combined virtual object can be held. For independent virtual objects, the independent virtual objects are held.

The independent virtual object refers to a virtual object composed of multiple geometric bodies, the geometric bodies can be understood as the smallest non-detachable editing elements in the editor, and the user can hold the independent virtual object.

After defining a combined virtual object, it is necessary to configure holding parameters for the combined virtual object before the user can hold, take and put, or fetch the combined virtual object. For example, the combined virtual object is taken out of the user's backpack, or the combined virtual object is taken from one place to another in the virtual scene, or the combined virtual object is held to perform tasks in the virtual scene.

In the embodiment of the present disclosure, two types of holding parameters are configured for the combined virtual object: a combined holding parameter and a sub-holding parameter. One combined virtual object is configured with only one combined holding parameter, and each sub-virtual object in the combined virtual object is configured with one sub-holding parameter. It can be understood that some sub-virtual objects in the combined virtual object may not be configured with sub-holding parameters.

The combined holding parameter can be understood as a virtual holding parameter, which is used to hold the entire combined virtual object, and the combined holding parameter can be understood as a holding parameter configured for the outermost parent nodes of the plurality of sub-virtual objects. When the user takes the combined virtual object out of the backpack, the combined virtual object is taken out of the backpack as a whole according to the combined holding parameter, and after the combined virtual object is taken out, the sub-virtual object can be taken and put according to the sub-holding parameter of the sub-virtual object.

For example, the combined holding parameter at least includes a combined position parameter, and the sub-holding parameter at least includes a sub-position parameter. The combined position parameter is used to describe the holding position when the avatar fetches and holds the virtual object, and the sub-position parameter is used to describe the holding position when the avatar holds the sub-virtual object, wherein the holding position of the combined virtual object and the holding position of the sub-virtual object can be expressed by three-dimensional coordinates.

Optionally, the combined holding parameter further includes a combined posture parameter, and/or the sub-holding parameter further includes a sub-posture parameter. The combined posture parameter is used to describe the posture of the combined virtual object, and the posture of the combined virtual object can be understood as the orientation or direction of the combined virtual object. The sub-posture parameter is used to describe the posture of the sub-virtual object, and the posture of the sub-virtual object can be understood as the orientation or direction of the sub-virtual object.

It should be noted that in the embodiment of the present disclosure, holding, fetching, or taking and putting the combined virtual object or the independent virtual object can be understood as that the hand of the avatar is in contact with the combined virtual object or the independent virtual object; or that the hand of the avatar is not in contact with the combined virtual object or the independent virtual object, and there is a certain distance therebetween, but the hand of the avatar can control the movement of the combined virtual object or the independent virtual object.

In addition, when a combined virtual object or an independent virtual object is held, it can be configured to be held by one hand or two hands, and the information of one-hand holding and two-hands holding can be included in the holding parameters.

S102, in response that a first fetching instruction is detected, displaying the combined virtual object according to the combined holding parameter; and/or, in response that a second fetching instruction is detected, displaying a corresponding sub-virtual object according to the sub-holding parameter.

The first fetching instruction is used to instruct to fetch the combined virtual object. The second fetching instruction is used to instruct to fetch the sub-virtual objection, the first fetching instruction and the second fetch instruction can be an instruction input by the user through the controller of the XR device, or an instruction input by means of gesture, voice, etc., which is not limited in the embodiment of the present disclosure.

When receiving the first fetching instruction on the combined virtual object, the combined virtual object is displayed according to the combined holding parameter, and the displaying here can be understood as displaying that the avatar fetches or holds the combined virtual object by hand according to the combined holding parameter. Similarly, displaying the corresponding sub-virtual object according to the sub-holding parameter can be understood as displaying that the avatar fetches or holds the sub-virtual object by hand according to the sub-holding parameters.

For example, in the embodiment of the present disclosure, the combined holding parameter at least includes a combined position parameter, and the sub-holding parameter at least includes a sub-position parameter. Correspondingly, in response that the first fetching instruction is detected, the combined virtual object is displayed according to the combined holding parameter and a control parameter, and/or in response that the second fetching instruction is detected, the corresponding sub-virtual object is displayed according to the control parameter and the sub-holding parameter. The control parameter includes a position parameter, and the position parameter is used to describe the position of the hand of the virtual role holding the combined virtual object and the sub-virtual object. When the user fetchs the combined virtual role, the display position of the combined virtual role can be determined by computering the combined holding parameters and the control parameters. Since the hand of the virtual role is usually displayed according to the control parameter, the combined virtual object will move following the hand of the virtual role, which reflects the hand of the virtual role holding the combined virtual object.

Similarly, when the user fetchs a sub-virtual object, the display position of the sub-virtual objection can be determined by computering the sub-holding parameters and the control parameters. Since the hand of the virtual role is usually displayed according to the control parameter, the sub-virtual object will move following the hand of the virtual role, which reflects the hand of the virtual role holding the combined virtual object. It should be noted that, the combined virtual objection is displayed according to the combined holding parameter and the control parameter, respective sub-virtual objects of the combined virtual objection can be located in a preset position, and also be maintained in the current relative portion, and in this case, the combined virtual object can be understood as a bounding box containing the respective sub-virtual objects.

the combined holding parameter can further include a combined posture parameter and/or the sub-holding parameter can further include a sub-posture parameter. When the user fetchs the combined virtual object, the display position and posture of the combined virtual object are determined by computering the holding parameter and the control parameter. When the user fetchs a sub-virtual object, the display position and posture of the sub-virtual object are determined by computering the sub-holding parameter and the control parameter.

When the method in the present embodiment is applied to an XR device, the control parameter is a control parameter of the controller of the XR device, and the controller of the XR device can be a handheld control device, such as a handle, a glove, etc. The control parameter of the controller include a position parameter and a posture parameter of the controller, and in XR scene, the position parameter and the posture parameter of the hand of the virtual role generally correspond to the position parameter and the posture parameter of the controller reflect.

FIG. 8 is a schematic diagram of holding a combined virtual object. As shown in FIG. 8, the avatar needs to take out a deck of playing cards from the user's backpack, and the combined virtual object is a deck of playing cards. The user needs to open the user's backpack first, and a thumbnail of the playing cards is displayed in the user's backpack. The user can control the virtual hand model to click the thumbnail of the playing cards, and then, the hand model takes out the whole deck of playing cards from the user's backpack in the form of an “entire group”, and takes it out in the form of free holding point or short holding. The holding point can be understood as the holding position of the combined virtual object, and the short holding refers to the release of the combined virtual object after releasing the button when holding the combined virtual object. Optionally, there is no physical movement of the objects in the group during the taking-out process.

After released by the hand model, each playing card in the whole deck of playing cards moves according to a preset physical law. For example, each playing card falls onto the ground or a fixed object according to the law of gravity, or is suspended in space. The user can select to pick up the whole deck of playing cards again, or he/she only picks up one playing card of them at each time according to the sub-holding parameter of each playing card. Optionally, when the hand model fetches a single playing card, it can touch other playing cards, and the collision will affect the positions of other playing cards, so that the operation on the combined virtual object in the virtual scene is consistent with the operation on the real object in the real environment, thus bringing the user an immersive experience.

FIG. 9 is another schematic diagram of holding a combined virtual object. As shown in FIG. 9, the virtual role needs to take out a combined virtual object consisting of a pair of table tennis rackets, a plurality of table tennis balls and a plate from the user's backpack. The user needs to open the user's backpack first, and a thumbnail of the combined virtual object is displayed in the user's backpack. The hand model clicks the thumbnail, and then, the hand model takes out two table tennis rackets, a plurality of table tennis balls and one plate from the user's backpack in the form of an “entire group”. Optionally, there is no physical movement of the objects in the group during the taking-out process.

After released by the hand model, each sub-virtual object moves according to a preset physical law. For example, the plate and rackets are suspended in space, and the ball has physical movement. The ball moves and falls on or off the plate. When the subjects are picked up again, one subject can be picked up according to the holding parameter of the sub-virtual object, and multiple objects can be placed on one object. For example, the plurality of table tennis balls can be placed on the plate, and the plate and the table tennis balls on the plate can be picked up as a whole.

In the scenes shown in FIGS. 8 and 9, the user needs to firstly take the combined virtual object out of the user's backpack as a whole according to the combined holding parameter, and then he/she can fetches each sub-virtual object according to the sub-holding parameter of each sub-virtual object. Of course, the scenes of the embodiment of the present disclosure are not limited to these scenes. When playing in the virtual scene, the virtual role can also move the combined virtual object from one place to another; and in this scene, the fetching of the combined virtual object and the fetching of the sub-virtual object can be triggered by different fetching instructions.

In the present embodiment, a combined virtual object is displayed, the combined virtual object includes a plurality of sub-virtual objects, the combined virtual object is configured with a combined holding parameter, and at least one sub-virtual object in the combined virtual object is configured with a sub-holding parameter, respectively; in response that a first fetching instruction is detected, the combined virtual object is displayed according to the combined holding parameter; and/or, in response that a second fetching instruction is detected, a corresponding sub-virtual object is displayed according to the sub-holding parameter. In this method, the combined virtual object is configured with the combined holding parameter and the sub-holding parameters, and the entire combined virtual object can be held through the combined holding parameter, and each sub-virtual object in the combined virtual object can be held through the sub-holding parameter. It can not only holding the combined virtual object to implement the operation of moving a plurality of sub-virtual objects at a same time, etc. which is more convenient, but also holding a sub-virtual object of them to perform the operation of moving the sub-virtual object, etc., which is more flexible.

On the basis of the above embodiment, on or more embodiments of the present disclosure provides a method for holding a virtual object. The present embodiment focuses on the configuration of holding parameters of a combined virtual object, and configuring the combined holding parameter and the sub-holding parameters for the combined virtual object after the combined virtual object is created. In one implementation, after the combined virtual object is created, the combined holding parameter and the sub-holding parameters are automatically configured for the combined virtual object, which does not require the user to perform any operation, and can avoid the user forgetting to set the holding parameters. In another implementation, after the combined virtual object is created, the user manually configures the combined holding parameter and the sub-holding parameter for the combined virtual object.

FIG. 10 is a flow chart of a method for holding a virtual object provided by one or more embodiments of the present disclosure. The present embodiment is illustrated by taking manual configuration as an example. As shown in FIG. 4, the method provided in the present embodiment includes the following steps.

S201. In response to a configuration request, displaying a configuration interface.

After the combined virtual object is created, the user can send a configuration request under any circumstances. For example, when the combined virtual object is released, a configuration request is triggered; or when the user needs to fetch the combined virtual object, it is found that the combined virtual object is not configured with holding parameters, then a configuration request is triggered.

S202. Receiving a combined holding parameter and sub-holding parameters of a combined virtual object input by a user through the configuration interface, wherein the combined virtual object includes a plurality of sub-virtual objects, the combined virtual object is configured with the combined holding parameter, and at least one sub-virtual object in the combined virtual object is configured with a sub-holding parameter, respectively.

For example, the combined holding parameter include three parameters: grabbing mode, object reset and grabbing position; and each parameter has multiple values for the user to select. For example, the grabbing mode includes releasing the button to release and releasing the button without releasing. Releasing the button to release means that when the user fetches the combined virtual object, if the button is released (for example, the button of the controller is released), the combined virtual object will leave the hand of the virtual role. Releasing the button without releasing means that the combined virtual object will not leave the hand of the virtual role after the button is released, that is, the combined virtual object will always follow the movement of the user's hand. Releasing the button to release is also called short holding, and releasing the button without releasing is also called long holding.

Object reset refers to whether the position of the object is reset after the virtual role releases the button, that is, whether the object returns to the default position.

The grabbing position refers to a position grabbed by the hand when the hand of the virtual role grabs the combined virtual object. The grabbing position can be a free position or a fixed position. The free position means that the specific grabbing position is not limited. After the grabbing position of the combined virtual object is set as free position, the left and right hand models corresponding to the holding position will be generated on the combined virtual object. The fixed position can be defined by the user himself/herself, or several positions can be provided for the user to select.

The sub-holding parameter also includes grabbing mode, object reset and grabbing position, which have the same functions as the three parameters in the combined holding parameter, and the setup process thereof is similar.

FIG. 11 is a schematic diagram of an entry of a configuration interface of holding parameters of a combined virtual object. As shown in FIG. 11, the user opens a parameter setup interface of the combined virtual object, and the parameter setup interface can include the parameters required for the setup of the combined virtual object. The “holding point” in the parameter setup interface is the entry of the configuration interface of the holding parameters of the combined virtual object, and after the user clicks the “holding point”, the configuration interface is entered.

Optionally, the configuration interface further includes a combined holding parameter configuration option and a sub-holding parameter configuration option. After the user selects the combined holding parameter configuration option, the configuration interface of the combined holding parameter is entered, and after the user selects the sub-holding parameter configuration option, the configuration interface of the sub-holding parameters is entered.

FIG. 12 is a schematic diagram of a configuration interface of a combined holding parameter or a sub-holding parameter. As shown in FIG. 12, the configuration interface includes a switch control for adding holding points. After the user selects to add holding points, the parameters of grabbing mode, object reset and grabbing position set by the user will take effect. If the user selects not to add holding points, the parameters of grabbing mode, object reset and grabbing position set by the user will not take effect.

S203. Displaying the combined virtual object.

S204. in response that a first fetching instruction is detected, displaying the combined virtual object according to the combined holding parameter; and/or, in response that a second fetching instruction is detected, displaying a corresponding sub-virtual object according to the sub-holding parameter.

The specific implementation of steps S203 and S204 refers to the description of the embodiment, and details will not be repeated here.

In the method of the present embodiment, the user is provided with the setting function of the holding parameters of the combined virtual object, and the user can selects to configure the combined holding parameter and/or sub-holding parameters for the combined virtual object according to his/her own needs, so that the configuration of the holding parameters of the combined virtual object is more flexible and meets the personalized needs of different users.

For a combined virtual object customized by the user, holding parameters can be set for the combined virtual object in the publishing process of the combined virtual object. In the editing space of the editor, the user can single-select or multi-select virtual objects to publish props, single-selected virtual objects published as independent virtual objects, multi-selected virtual objects published as a combined virtual object.

Taking the multi-selected publishing as an example, the user publishes a deck of playing cards, and multi-selects all cards to publish. When used in a virtual scene, a deck of cards can be drawn out, and each card can be individually drawn for playing.

FIG. 13 is a schematic diagram of the transformation of a publishing interface after the virtual object is created, and FIG. 13 is a schematic diagram of publishing an independent virtual object. The publishing process of a combined virtual object is the same as the publishing process of an independent virtual object. As shown in FIG. 13, after creating a virtual object in the editor, the user clicks the “Save Subject” control shown in FIG. 13(a) to save the virtual object, and the interface is transformed to that shown in FIG. 13(b); after the user clicks the “Publish” control, the interface is transformed to that shown in FIG. 13(c). The interface shown in FIG. 13(c) displays two types of publishing for the user to select: publishing to the source material library and publishing props to the backpack. Only the virtual objects published as props need to be configured with holding parameters, while the virtual objects published as source materials do not need to be configured with holding parameters.

FIG. 14 is a schematic diagram of the publishing flow of a combined virtual object provided by the one or more embodiments of the present disclosure. As shown in FIG. 8, the method provided by the present embodiment includes the following steps.

S301. Selecting a combined virtual object and starting publishing.

S302. Judging whether the authority of the combined virtual object is an only usable object.

If the authority of the combined virtual object is an only usable object, it is determined that the publishing fails. If the authority of the combined virtual object is not an only usable object, step S303 is executed.

S303. Selecting the publishing type as publishing as a prop.

Publishing types include publishing as a source material and publishing as a prop. When the user selects publishing as a prop, step S304 is executed. If the user selects publishing as a source material, the publishing flow of the source material is executed, and details will not be described here.

S304. Judging whether the prop is in compliance.

For example, it is judged whether one or more of the size, capacity or asset type of the prop is in compliance, and if it is in compliance, step S305 is executed, and if it is not in compliance, it is determined that the publishing fails.

S305. Detecting whether each sub-virtual object in the combined virtual object is configured with a sub-holding parameter.

If all sub-virtual objects in the combined virtual object are configured with sub-holding parameters, step S306 is executed, and if any sub-virtual object in the combined virtual object is not configured with a sub-holding parameter, step S307 is executed.

S306. Automatically configuring a combined holding parameter for the combined virtual object.

S307: Processing according to a configuration option selected by the user.

The configuration options include automatic configuration and manual configuration. When the user selects manual configuration, processing according to the configuration option selected by the user includes: closing the publishing process and displaying a first prompt message, the first prompt message being used to prompt that the publishing of the combined virtual object has been cancelled.

When the user selects automatic configuration, processing according to the configuration option selected by the user includes: automatically configuring sub-holding parameters for sub-virtual objects that are not configured with sub-holding parameters in the combined virtual object; after all sub-virtual objects in the combined virtual object are configured with sub-holding parameters, automatically configuring a combined holding parameter for the combined virtual object; after the configuration of the combined holding parameter is completed, determining that the combined virtual object is published successfully.

For example, after the user selects publishing props to the backpack in FIG. 13(c), the interface switches to that shown in FIG. 15(a). After the user selects manual configuration, that is, “manually add” in the figure, it is prompted through the prompt box that the publishing has been cancelled, that is, the publishing process has been interrupted, and the user needs to manually configure a sub-holding parameter for each sub-virtual object, and then restart the publishing process. If the user selects automatic configuration, that is, “automatically add” in the figure, the interface switches to that shown in FIG. 15(b), that is, the automatic configuration of the sub-holding parameters will not interrupt the publishing process, and the user clicks the “Publish” control in FIG. 15(b), then the publishing is successful. If the user selects to cancel the publishing in the step shown in FIG. 15(b), the sub-holding parameters automatically configured in the previous step will not disappear and are still valid, and the user does not need to set the sub-holding parameters again when publishing next time.

Optionally, FIG. 15(a) further includes a “holding point tutorial”, and the “holding point tutorial” is used to demonstrate the setting process of holding parameters, so that the user who adopts manual configuration can quickly understand the setting method of holding parameters.

Optionally, in some other embodiments of the present disclosure, when any sub-virtual object in the combined virtual object is not configured with a sub-holding parameter, the following prompt message, “The current object is not configured with a holding parameter, and only the holdable object can be published to the backpack”, is displayed while the configuration options are displayed.

S308: Succeeding in publishing.

S308 is executed after step S306, that is, after the configuration of the combined holding parameter is completed, it is determined that the combined virtual object is published successfully. Alternatively, if the user selects automatic configuration in step S307, step S308 is executed after automatically configuring the combined holding parameter and the sub-holding parameters for the combined virtual object.

In the present embodiment, in the publishing process of the combined virtual object, it is detected whether each sub-virtual object in the combined virtual object is configured with a sub-holding parameter, and if each sub-virtual object is configured with a sub-holding parameter, the combined virtual object is automatically configured with the sub-holding parameter; if any sub-virtual object in the combined virtual object is not configured with a sub-holding parameter, configuration options are displayed, the configuration options includes automatic configuration and manual configuration, and holding parameters are automatically or manually configured for the combined virtual object according to the configuration option selected by the user, thus improving the flexibility of the configuration of the combined virtual object.

It should be emphasized that an independent virtual object is displayed in the virtual scene, the independent virtual object is configured with a holding parameter, and in response that a third fetching instruction is detected, the independent virtual object is displayed according to the holding parameter of the independent virtual object. The third fetching instruction is used to instruct fetching the independent virtual object, and the third fetching instruction can be the instruction input by the user through the controller of XR device, and also can be instructions input by gesture, voice, and so on. The independent virtual object is different from the combined virtual object in that the independent virtual object has only one holding parameter, which has the same function as the sub-holding parameter of each sub-virtual object in the combined virtual object. The configuration manner and function thereof refer to the relevant description of the holding parameter of each sub-virtual object in the combined virtual object, details will not be repeated in the embodiment of the present disclosure.
