[0002] In a sandbox building game, in order to obtain higher freedom, the automatic adsorption alignment strength in the game scene for placing furniture or building materials is often reduced, so that the building modules or furniture often fail to align in the process of rapid placement. In the related art, based on the setting of the placement logic of the game, the player needs to recycle the modules that fail to align and then place them again, or needs to drag the modules that fail to align to adjust their positions so that the multiple modules that need to be aligned are aligned. The operation process of the above two ways is relatively cumbersome, which makes the game experience of the player poor. SUMMARY

[0024] To make the objectives, technical solutions and advantages of embodiments of the present application clearer, the technical solutions of the present application will be described below in detail with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0025] In sandbox building games, in order to obtain higher freedom, the threshold of automatic adsorption alignment is often reduced when the player builds or places virtual props, that is, more delicate placement is required to trigger automatic adsorption. If you want to quickly and not delicately, it is not easy to trigger automatic adsorption, resulting in misalignment. Therefore, it often happens that building modules or furniture cannot be aligned in the process of quick placement.

[0026] In the related art, the player usually needs to demolish the virtual props that have been built or placed to rebuild or place them again. Especially when the virtual props are furniture and the furniture has already put the items in it, due to the backpack capacity limit, the player cannot one-click the furniture to put it away, and often needs to manually transfer the items to the backpack or other containers first, and then put the furniture away and place it again. Further, for the mechanism with material loss logic, it will also cause the loss of the player's resources. Whether it is demolition and reconstruction or putting away and placing again, it will often bring the player negative emotions of resource loss or tedious operation.

[0027] Whether it is building or furniture placement, the whole process at least needs the player to pay more, to perform operations such as putting away, taking out or selecting, aligning or moving, placing, and a series of at least three steps of operations, which adds unnecessary tedious operations to the player and the experience is not good.

[0028] Therefore, based on this, the embodiment of the present application provides a virtual prop placement control method, device and electronic equipment, which can be applied to various game scenes that need to place virtual props.

[0029] The virtual prop placement control method in one of the embodiments disclosed in the present application can run on a local terminal device or a server. When the virtual prop placement control method runs on the server, this mode can be realized and executed based on a cloud interaction system, wherein the cloud interaction system includes a server and a client device.

[0030] In an optional embodiment, various cloud applications can be run under the cloud interaction system, for example: cloud games. Taking cloud games as an example, cloud games refer to a game mode based on cloud computing. In the running mode of cloud games, the running body of the game program and the presentation body of the game picture are separated, and the storage and running of the virtual prop placement control method are completed on the cloud game server. The client device is used for data reception, sending and game picture presentation. For example, the client device can be a display device close to the user side with data transmission function, such as a mobile terminal, a television, a computer, a palm computer, etc.; but the information processing is the cloud game server in the cloud. When playing the game, the player operates the client device to send operation instructions to the cloud game server, the cloud game server runs the game according to the operation instructions, encodes and compresses the game picture data, returns the data to the client device through the network, and finally decodes and outputs the game picture through the client device.

[0031] In an optional embodiment, taking a game as an example, the local terminal device stores a game program and is configured to present a game screen. The local terminal device is configured to interact with a player through a graphical user interface, i.e., a conventional game program is downloaded and installed on an electronic device and then run. The local terminal device can provide the graphical user interface to the player in various ways, for example, the graphical user interface can be rendered on a display screen of the terminal, or provided to the player through holographic projection. For example, the local terminal device can include a display screen configured to present a graphical user interface including a game screen, and a processor configured to run the game, generate the graphical user interface, and control display of the graphical user interface on the display screen.

[0032] In a possible embodiment, the method for placing virtual props provided by the present application includes providing a graphical user interface through a terminal device. The terminal device can be the local terminal device mentioned above or a client device in the cloud interaction system mentioned above. The graphical user interface displays a game scene including a plurality of virtual props. The virtual props can be placed in the game scene by the player through a placing operation, or can be pre-set in the game scene and can be changed in pose by the player through a placing operation. As shown in the figure, the method includes the following steps: Figure 1

[0033] Step S102, in response to a first touch operation, determining a plurality of target props from the plurality of virtual props based on an operation touch point of the first touch operation.

[0034] The first touch operation usually acts on the target props that the player wants to perform the alignment operation. Since alignment usually means that two or more things are in order or in contact, the target props are at least two, and can be three or more.

[0035] The first touch operation can be a click operation on the target props, or a double-click operation, a long press operation, etc. For example, after the player double-clicks one virtual prop and clicks another virtual prop, the two virtual props are taken as target props; or the player long-presses one virtual prop and clicks two virtual props, and the three virtual props are taken as target props. The first touch operation usually needs to use a conventional touch operation as a starting operation to select the target props, and select other target props after the operation. In the above examples, the player's double-click or long-press operation on one virtual prop can be considered as the starting operation to select the target props.

[0036] Step S104, in response to a second touch operation acting on at least part of the target props, determining a reference prop and a to-be-moved prop in the target props according to the first touch operation or the second touch operation. ​

[0037] After identifying multiple target items, it is necessary to determine the base item and the item to be moved from among them. The second touch operation can be continuous with the first touch operation or discontinuous. For example, after identifying multiple target items and releasing the first touch operation, the second touch operation could be clicking on a target item, which can then be designated as the base item. In practice, to simplify user operation, the second touch operation is usually set to be continuous with the first touch operation; for example, the second touch operation could be a swipe operation starting from the touch point of the first touch operation. The specific method can be set according to requirements and is not limited here.

[0038] Since the purpose of the above method is to align multiple target props, a reference placement pose is usually required during the alignment process so that the multiple target props can be aligned based on the reference placement pose. The reference placement pose can be the placement pose of one of the target props, or it can be a reference placement pose calculated based on the placement poses of multiple target props. For example, when using the average placement pose of selected multiple target props as the reference placement pose, the center position of the placement positions of the multiple target props can be calculated as the reference position, or the average pose of the placement poses of the multiple target props can be calculated as the reference pose, etc.

[0039] When the placement of one target item needs to be used as a reference placement position, that target item can be called the base item. Other target items need to be moved and rotated with reference to the placement position of the base item. The base item and the item to be moved can be determined based on either the first touch operation or the second touch operation, or both. For example, the target item in a certain selection order can be designated as the base item according to the selection order of the first touch operation. Typically, the first or last selected target item can be set as the base item. The target item can also be selected based on the touch order of the second touch operation, using the same method as described above, which will not be elaborated here. Furthermore, when the second touch operation is a swipe operation, the base item can also be determined based on the swipe direction, for example, the target item pointed to by the swipe operation can be designated as the base item.

[0040] Step S106: Based on the placement of the reference item in the target item, update the placement of the item to be moved in the target item so that the item to be moved after the placement is updated is aligned with the reference item according to the preset rules.

[0041] In updating the relative placement poses of the plurality of target props, a reference placement pose is usually referred to. If the reference placement pose is not the placement pose of any of the plurality of target props, the placement pose of each target prop needs to be updated. If the reference placement pose is the placement pose of one of the target props, the placement poses of the other target props relative to the target prop need to be updated.

[0042] In a specific implementation, a preset rule is usually used to determine the reference placement pose and the manner of updating the placement poses of the target props. For example, the preset rule can be that the average placement pose of the selected plurality of target props is taken as the reference placement pose, and the plurality of target props after alignment are updated to the placement poses in the average placement pose; the preset rule can also be that the first selected target prop is taken as a reference prop, and the other target props after alignment are updated to the placement pose of the reference prop, and the other target props after alignment are as close as possible to the placement position of the reference prop, and the like. The preset rule can be set according to specific needs, which is not limited herein.

[0043] The above-mentioned virtual prop placement control method determines a plurality of target props from a plurality of virtual props based on an operation touch point of a first touch operation in response to the first touch operation; determines a reference prop and a target prop to be moved in the target props according to the first touch operation or a second touch operation acting on at least part of the target props in response to the second touch operation; and updates the placement pose of the target prop to be moved in the target props according to the placement pose of the reference prop in the target props, so that the target prop to be moved after the placement pose is updated is aligned with the reference prop according to a preset rule. This way simplifies the operation of aligning virtual props in the game and improves the game experience of the player.

[0044] The following embodiments provide a specific way of determining a plurality of target props based on an operation touch point of a first touch operation.

[0045] In a specific implementation, the target prop can be two, and correspondingly, the above-mentioned first touch operation includes a first sub-operation and a second sub-operation; the two sub-operations can act on the two virtual props respectively, so as to determine the two virtual props as target virtual props. The first sub-operation and the second sub-operation can be the same type of touch operation, or can be different types of touch operation. For example, the first sub-operation can be a click operation, and the second sub-operation can be a long press operation, or vice versa; or the first sub-operation and the second sub-operation are both click operations, and the like. The specific way can be set according to the needs, which is not limited herein.

[0046] Users typically use two fingers to touch two virtual items. The touching process usually has a sequence; touching a virtual item first can be considered the first sub-operation, and touching it later can be considered the second sub-operation. In this case, in response to the first sub-operation on the first item among multiple virtual items, the touch position of the first sub-operation can be monitored; in response to the touch position of the first sub-operation remaining on the first item, and in response to the second sub-operation on the second item among multiple virtual items, both the first and second items can be identified as target items. That is, if the user presses the first item and then presses the second item, both the first and second items will be identified as target items.

[0047] The following embodiments provide a method for determining a reference prop and a prop to be moved in the target prop based on a second touch operation applied to at least a portion of the target prop, according to either the first touch operation or the second touch operation.

[0048] In practical implementation, the first touch operation may include a first sub-operation applied to the first prop and, when applied to the second prop, a second touch operation is generated. In response to the second touch operation applied to the first and / or second prop, the reference prop and the prop to be moved in the first and second props can be determined according to the order in which the first and second sub-operations are generated. The aforementioned second touch operation can be a sliding operation on the first prop, a sliding operation on the second prop, or a sliding operation on both the first and second props simultaneously. Since the first and second sub-operations usually have a sequential generation order, the prop affected by the first sub-operation can be pre-set as the reference prop, and the other as the prop to be moved; or the reverse setting can also be used.

[0049] Specifically, the aforementioned second touch operation can be a first sliding operation consecutive to the first sub-operation, and a second sliding operation consecutive to the second sub-operation. In response to the first sliding operation acting on the first prop and the second sliding operation acting on the second prop satisfying a first condition, the reference prop and the prop to be moved in the first and second props are determined according to the generation order of the first and second sub-operations. The first condition includes at least: the sliding direction of the first sliding operation points to the second prop, and / or the sliding direction of the second sliding operation points to the first prop. When the first condition is that the first sliding operation points to the second prop and the second sliding operation points to the first prop, the two operations can be considered as a "pinch operation," such as... Figure 2 As shown. Figure 2 The arrow in the text indicates the direction of the sliding operation. Additionally, the first condition can also include restrictions on the length of the sliding trajectory or the sliding time; these can be set according to requirements and are not specified here.

[0050] In the case that the second touch operation is determined to include a third sliding operation continuous with the first sub-operation, the first prop is determined as the reference prop and the second prop is determined as the prop to be moved, in response to the third sliding operation acting on the first prop satisfying a preset second condition; or the first prop is determined as the prop to be moved and the second prop is determined as the reference prop, in response to the third sliding operation acting on the first prop satisfying the second condition. The preset first condition includes at least that the sliding direction of the third sliding operation points to the second prop, i.e., the sliding operation points from the first prop to the second prop. At this time, the second sub-operation can have been released.

[0051] Further, the touch position of the second sub-operation can be required to stay on the second prop to trigger the determination of the reference prop and the prop to be moved. Specifically, the first prop is determined as the reference prop and the second prop is determined as the prop to be moved, in response to the third sliding operation acting on the first prop satisfying the second condition and the touch position of the second sub-operation staying on the second prop.

[0052] The following embodiments provide a specific way of updating the placement pose of the prop to be moved in the target props according to the placement pose of the reference prop in the target props, so that the prop to be moved after the update of the placement pose is aligned with the reference prop according to a preset rule.

[0053] The Chinese interpretation of "alignment" is: make two or more things fit or touch each other in order. Usually, it refers to arranging two or more machine parts, especially parts that should be parallel or in line, to the correct position or direction.

[0054] In actual production and life, people can use different reference objects to define the "alignment state" they need. In this method, "alignment" can be defined by the following rules:

[0055] (1) The placement pose of the prop to be moved after the update is parallel to the placement surface of the reference prop, and the projection of the geometric center of the prop to be moved after the update on the placement surface is aligned with the projection of the geometric center of the reference prop on the placement surface.

[0056] (2) The placement pose of the prop to be moved after the update is parallel to the placement surface of the reference prop, and the first plane of the prop to be moved after the update is coincident with the second plane of the reference prop.

[0057] In both of the above rules, additional restrictions can be added, such as placing the updated moveable item and the reference item on the same placement plane. Furthermore, restrictions can include bounding box collisions between the updated moveable item and the reference item, or minimum distances between the updated moveable item and the reference item being less than a preset distance. These can be set according to requirements and are not specified here.

[0058] Generally speaking, when aligning two target items, the current position of the base item is used as the reference position. The current position of the item to be moved can be updated directly based on the current position of the base item and the current position of the item to be moved.

[0059] The aforementioned current placement posture can include the placement posture and the current placement position. When updating the current placement posture of the item to be moved, it is first necessary to determine the target rotation parameters of the item to be moved based on the placement posture of the reference item and the placement posture of the item to be moved, and control the item to be moved to rotate according to the target rotation parameters to rotate to the updated placement posture. Then, based on the current placement position of the reference item and the current placement position of the rotated item to be moved, the target movement parameters of the item to be moved are determined, and the item to be moved is controlled to move according to the target movement parameters to move to the updated current placement position.

[0060] The placement posture of the virtual props can be represented by the planar posture parameters and normal posture parameters of the placement surface. The placement surface can be the surface of the virtual prop that contacts the game scene. For example... Figure 3 As shown, placement surface a is the placement surface of the reference prop, and placement surface b is the placement surface of the prop to be moved. Corresponding to the planar attitude parameters and normal attitude parameters, the target rotation parameters include planar rotation parameters and normal rotation parameters.

[0061] When the preset rules include that the placement surface of the prop to be moved is parallel to the placement surface of the reference prop, the planar rotation parameters of the prop to be moved are calculated based on the planar attitude parameters of the reference prop's placement surface and the planar attitude parameters of the prop to be moved's placement surface; for example... Figure 3 The arrows indicate the direction of rotation of the item to be moved, and the central angle corresponding to the arrow indicates the rotation angle of the item to be moved. Then, the item to be moved is controlled to rotate according to the planar rotation parameters so that the placement surface of the item to be moved is parallel to the placement surface of the reference item.

[0062] Generally, the base prop and the prop to be moved each have their corresponding bounding boxes, which are invisible. A bounding box, also called a "collision box," is a slightly larger but simpler geometric object used to approximate a complex geometric object (i.e., the virtual prop mentioned above). Therefore, the base prop is located in the first bounding box; the prop to be moved is located in the second bounding box. When the preset rule also includes that a specified edge of the projection surface of the prop to be moved is parallel to a specified edge of the projection surface of the base prop, it is also necessary to determine the normal rotation parameters of the prop to be moved. Specifically, it is necessary to obtain the first projection surface of the first bounding box of the base prop on the current placement surface of the base prop, and the second projection surface of the second bounding box of the prop to be moved on the current placement surface of the prop to be moved after rotation; then, based on the first and second projection surfaces, the normal rotation parameters of the prop to be moved are determined; the prop to be moved is controlled to rotate according to the normal rotation parameters so that a specified edge of the second projection surface of the prop to be moved is parallel to a specified edge of the first projection surface of the base prop. The normal rotation parameter can be considered as the parameter by which the object to be moved rotates around the normal axis that passes through its geometric center.

[0063] When determining the normal rotation parameters based on the first projection plane and the second projection plane, it is first necessary to determine the specified edge of the second projection plane and the specified edge of the first projection plane based on the positional relationship between the second projection plane and the first projection plane; then, based on the specified edge of the second projection plane and the specified edge of the first projection plane, the normal rotation parameters of the prop to be moved are calculated.

[0064] The following details the method for determining specified edges of the second and first projection planes based on their positional relationship when the first projection plane is a first polygon and the second projection plane is a second polygon. For example... Figure 4 As shown, the right side represents the first polygon corresponding to the base prop, and the left side represents the second polygon corresponding to the prop to be moved; both are squares. Obtain the centroid of the first polygon and the centroid of the second polygon; obtain the line connecting the centroid of the second polygon and the centroid of the first polygon, as shown... Figure 4 As shown in L; then, the first edge of the second polygon that intersects with the connecting line is determined as the designated edge of the second projection plane, as shown in... Figure 4 As shown in Figure A; the second side of the first polygon that intersects with the connecting line is defined as the designated side of the first projection plane, as follows. Figure 4 As shown in B.

[0065] If the line passes through the vertices of the first polygon and / or the second polygon, such as Figure 5 As shown, line L passes through the vertex of the prop to be moved. A specified edge is randomly selected from the two edges adjacent to the vertex, representing the first polygon and / or the second polygon. Figure 5 As shown in Figures A and B.

[0066] When the first projection plane is a circle and the second projection plane is a third polygon, the geometric center of the circle and the geometric center of the third polygon are also needed to be obtained; then the line connecting the geometric center of the circle and the geometric center of the third polygon is obtained; and the intersection point of the circle and the line is determined as the specified point of the first projection plane; and the edge of the third polygon intersecting with the line is determined as the specified edge of the second projection plane. Similar to the above case, if the line passes through a vertex of the third polygon, a certain edge adjacent to the vertex can be randomly selected as the specified edge.

[0067] In the above case, the to-be-moved prop needs to be rotated to a posture in which the specified edge thereof is parallel to the tangent line of the circle. Therefore, when determining the normal rotation parameter of the to-be-moved prop, the tangent line corresponding to the specified point of the circle is determined based on the specified point of the circle; and then the normal rotation parameter of the to-be-moved prop is calculated based on the tangent line and the specified edge of the second projection plane. The normal rotation parameter can make the specified edge of the to-be-moved prop after rotation parallel to the tangent line.

[0068] When the preset rule further includes that the placement plane of the to-be-moved prop and the placement plane of the reference prop are in the same horizontal plane, the distance between the plane corresponding to the placement plane of the to-be-moved prop after rotation and the plane corresponding to the placement plane of the reference prop is calculated after the placement plane of the to-be-moved prop is made parallel to the placement plane of the reference prop, and the calculation result is determined as the normal movement parameter of the to-be-moved prop; wherein the normal movement parameter includes a movement direction and a movement distance; and then the to-be-moved prop is controlled to move according to the normal movement parameter.

[0069] If the preset rule further requires that the to-be-moved prop is in surface contact with the reference prop, the plane movement parameter of the to-be-moved prop can be determined based on the line connecting the geometric center of the first projection plane of the placement plane of the to-be-moved prop after movement and the geometric center of the second projection plane of the placement plane of the reference prop, and the movement parameter also includes a movement direction and a movement distance; and then the to-be-moved prop is controlled to move according to the plane movement parameter until the to-be-moved prop is in surface contact with the reference prop.

[0070] The preset rule can further require that the geometric center of the to-be-moved prop is aligned with the projection of the geometric center of the reference prop on the placement plane on the basis of requiring that the to-be-moved prop is in surface contact with the reference prop. At this time, the relative position parameter between the midpoint of the specified edge of the to-be-moved prop after movement and the midpoint of the specified edge of the reference prop can be calculated, and the to-be-moved prop is controlled to move according to the plane movement parameter until the to-be-moved prop is in surface contact with the reference prop.

[0071] After the object to be moved is moved, the midpoint of the designated edge of the second projection surface of the object to be moved coincides with the end point of the designated edge of the first projection surface of the reference object. In some cases, if the shapes of the object to be moved and / or the reference object are irregular, the object to be moved and the reference object may not yet be in contact when the two midpoints coincide, such as... Figure 6 As shown. Therefore, after moving: it is necessary to determine whether the second bounding box of the object to be moved touches the first bounding box of the reference object; if not, control the object to be moved to move in the direction indicated by the planar movement parameters until the second bounding box of the object to be moved touches the first bounding box of the reference object.

[0072] This invention also provides another method for controlling the placement of virtual props. This method... Figure 1 This method is implemented based on the method shown. By adding a two-finger pinch interaction gesture and through a series of calculations and logical judgments, it achieves the alignment of two virtual props, such as furniture or building modules, thus reducing the player's operational burden.

[0073] This method requires recognizing the player's pinching motion on the screen, identifying the target object touched by the two fingers, determining the order of their contact, and extracting the collision information features. Then, the orientation of the two objects is corrected to the same horizontal plane, and their projected shapes on the horizontal plane are taken. Based on logical calculations and judgments, one of the objects is moved until it aligns with the other object.

[0074] The aforementioned target items can be furniture commonly found in survival games, or items with placement characteristics such as foundations and building components used in the construction process.

[0075] During the two-finger pinching process described above, the touch points of the two fingers on the screen will be sequential. The virtual prop corresponding to the model collision box into which the first touch point falls is defined as the base prop (also called the "base component"). The virtual prop corresponding to the model collision box into which the second touch point falls is the prop to be moved (also called the "moving component"), such as... Figure 7 , where 1 is the first landing point and 2 is the second landing point.

[0076] The specific process of aligning two virtual items using logical judgment is as follows:

[0077] The placement surface of the reference component is 'a', and the placement surface of the moving component is 'b'. First, determine if 'a' and 'b' are parallel. If not, rotate 'b' until it is parallel to 'a'. When 'a' and 'b' are parallel, project the collision boxes of the reference component and the moving component onto the placement surface directions, with projection surfaces a1 and b1 respectively. Connect the centroids of the two projection surfaces with a line L, as shown... Figure 4As shown. The line L must pass through a certain edge of a1 and b1 respectively. Respectively A and B. If the L described above just passes through a certain vertex of a1 or b1, randomly select a certain edge of the vertex as A or B. As shown Figure 5 At this time, the reference component remains stationary, and the rotating moving component is rotated until A and B are parallel.

[0078] Further, the midpoint of A and B is defined as C1 and C2. The moving component is moved to make A and B coincide, while a and b are in the same horizontal plane, and C1 and C2 coincide.

[0079] The direction of the moving process of the moving component is recorded as α. After moving the component, it is judged whether the collision boxes of the reference component and the moving component have contacted. If not, continue to move the moving component in the direction of α until the two collision boxes are in contact. This can solve the problem of aligning components with different posters and non-standard cylindrical collision boxes, as shown Figure 6 At this time, the alignment of the two components is completed, as shown Figure 8

[0080] The following situations may occur during the above alignment process and can be handled accordingly:

[0081] 1. If there is an obstacle near the reference component, so that the moving component cannot be placed there, it is judged that alignment is not possible, and a prompt text is popped up.

[0082] 2. If one or both of a1 or b1 is a circle, the moving component is moved to be tangent, as shown Figure 9

[0083] The above series of operations are program operation processes, which do not need to be displayed on the screen for the player to see. The player only needs to see the alignment result.

[0084] The above method realizes the alignment of two furniture or building modules by adding a double-finger pinch interactive gesture and a series of calculations and logical judgments. It greatly reduces the operation cost of re-placing due to misoperation when the player places furniture or builds buildings, making the operation more convenient and efficient, and improving the player's game experience.
