Description

Technical Field

[0001] The present invention relates to the field of game technology, and in particular to a method for processing the drop of a virtual object, a device for processing the drop of a virtual object, an electronic device, and a computer-readable storage medium. Background Art

[0002] With the development of gaming technology and the widespread adoption of smart devices, gaming has become an important form of entertainment in people's daily lives. In some games, when players defeat a boss or enemy character, or collect resources within a game scene, virtual objects may drop from them. By manipulating the drop trajectory of virtual objects to more closely resemble the way objects drop in the real world, the player's gaming experience can be effectively enhanced. For these drop scenarios, either the virtual object is dropped along a fixed trajectory, or the server calculates the trajectory and sends it to the client. Fixed trajectories result in a fixed drop trajectory, lacking dynamic performance and resulting in poor performance. Dynamically calculating the trajectory on the server relies on server-side computation, significantly increasing the server's computational burden, cost, and performance overhead.

[0052] The embodiments of the present invention include the following advantages:

[0053] In an embodiment of the present invention, in a game, in an item drop scene, a game client can respond to an item drop instruction, determine a virtual object corresponding to the item drop instruction, and obtain item parameters corresponding to the virtual object.

[0059] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] As an example, in-game item drops can typically be implemented in the following ways: 1. Dropped items are generated directly on the ground, and a fixed trajectory effect is played between the boss's death and the item's spawning to create a transition; 2. The server performs a unified motion trajectory simulation. When the boss dies, the server calculates the item's trajectory and then synchronizes the item's current position to each client in real time, ensuring that each client sees the same trajectory and position as the dropped item. However, the first solution has the advantage of being simple to implement, as the dropped items are stationary, and the directly generated positions of each client are guaranteed to be synchronized. However, its disadvantage is also obvious: it lacks the physical motion trajectory of the item in the air and after it lands. Even if trajectory effects are used to compensate for this, the trajectory effects are fixed and cannot be dynamically expressed, resulting in poor performance. For the second solution, although it can simulate the motion trajectory of dropped objects, it can only simulate simple motion trajectories, such as vertical drop, upward throw, horizontal throw, etc., and for some fine and complex motion trajectories: for example, after landing, the dropped objects hit the slope and need to bounce back, the kinetic energy decays, and roll until they stop, the fine performance is relatively weak, and it also relies on the server's calculations, which easily increases the server's computing pressure.

[0061] In this regard, one of the core inventive aspects of the present invention lies in its application to game clients. During gameplay, when an item is dropped, the game client can respond to the item drop command and determine the virtual object corresponding to the item drop command. Then, based on the item parameters corresponding to the virtual object, a matching virtual object model is created. This virtual object model can be a model visible and operable by the player in the game scene. By creating a model that fits the virtual object, it is possible to avoid situations such as the model sinking, clipping, or floating in the air during collisions during the game item drop, thereby improving the realism of the item drop and optimizing the performance. Simultaneously, while creating the virtual object model, the game client can obtain the drop point corresponding to the virtual object sent by the server. Based on this drop point, the game client then determines the motion parameters of the model in the game scene. Based on the motion parameters, the game client controls the virtual object model to execute the corresponding drop motion starting from the drop point. This allows the client to calculate the motion trajectory, effectively reducing the computational burden on the server. Furthermore, based on the motion parameters determined at the same drop point, the motion trajectory calculated by each client is identical, ensuring that the drop process of the same item on different clients is identical and ensuring the synchronization of the item drop motion trajectories in the game.

[0062] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present invention, some technical features involved in the embodiments of the present invention are explained and illustrated below:

[0063] Virtual objects can be virtual items in the game, such as art models designed by artists that are associated with the game scene and gameplay. These art models are invisible and inoperable to the player in the game. To address this, during the item drop process, the desired item is first determined, and then a physical rigid body corresponding to the item is created, i.e., the virtual object model. This model is visible and operable to the player in the game scene.

[0064] Each virtual object has an origin in the object coordinate system. This origin can be used to establish an object coordinate system for the virtual object. Different virtual objects can correspond to different object coordinate systems. Correspondingly, the scene coordinate system can be the spatial coordinate system corresponding to the game scene. A game scene only corresponds to one spatial coordinate system.

[0065] Specifically, refer to Figure 1 , shows a flowchart of a method for handling a drop of a virtual object provided in an embodiment of the present invention, which may specifically include the following steps:

[0066] Step 101: In response to an item drop instruction, determine a virtual object corresponding to the item drop instruction, and obtain item parameters corresponding to the virtual object, wherein the virtual object corresponds to an object coordinate system, and the item parameters are parameters determined based on the object coordinate system;

[0067] In an embodiment of the present invention, it can be applied to a game client (hereinafter referred to as the client), which can be an application running on an electronic device. During the game, the client can implement corresponding game content by performing corresponding data interaction with the server.

[0068] In the game, item drops may include items dropped in the game scene when the player kills the corresponding game boss or enemy player character, collects a resource object (such as ore, trees, etc.) in the game scene, opens a treasure chest, etc. The item drop instructions may include resource object drop instructions and loot drop instructions, etc., which correspond to different item drop scenarios in the game.

[0069] In a specific implementation, when an item drops in the game, the server can send an item drop command to the client. The client can then determine the virtual object corresponding to the item drop command and obtain the item parameters corresponding to the virtual object. This virtual object is not yet a model displayed to the player in the game scene, but rather determines what item will be dropped in the game scene. Therefore, in order to display the corresponding model in the game scene so that the player can pick up the model and other operations, it is necessary to build an appropriate virtual object model based on the corresponding item parameters of the virtual object.

[0070] Step 102: determining the vertex coordinates of each vertex in the virtual object in the object coordinate system according to the object parameters, and constructing a virtual object model corresponding to the vertex coordinates;

[0071] For virtual objects, which are invisible and inoperable to players in the game, in order to make the virtual objects visible and operable (i.e., have physical collisions in the game scene), it is necessary to add corresponding physical rigid bodies to the virtual objects so that they can be supported by the ground in the game scene. The shape of the physical rigid body can include basic geometric shapes, such as cubes, spheres, capsules, or custom polygons. For example, assuming that the virtual object is a tetrahedron crystal, a basic geometric shape body, such as a sphere, can be added to the tetrahedron crystal, so that the tetrahedron crystal can have collisions in the game scene and can stop when it falls to the ground of the game scene.

[0072] It should be noted that for virtual objects, they can be art models designed by artists. After adding the corresponding physical rigid body to the art model, a virtual object model with the appearance corresponding to the art model and collision effect can be obtained in the game scene. Players can operate the virtual object model in the game, such as picking it up.

[0073] Among them, in the process of adding a physical rigid body, if the physical rigid body and the virtual object are not well fitted, when the volume of the physical rigid body is smaller than the volume of the virtual object, when the constructed virtual object model falls to the ground of the game scene, although the physical rigid body is supported by the game ground, a part of the virtual object model will sink into the ground. Moreover, considering that the virtual object model will collide and bounce continuously until it stops on the ground, and the collision is based on the physical rigid body, each collision will cause the virtual object model to sink into the wall or the ground, seriously affecting the performance of the virtual object in the game; when the volume of the physical rigid body is larger than the volume of the virtual object, when the constructed virtual object model falls to the ground of the game scene, the virtual object model will float, which also affects the performance of the virtual object in the game. To this end, it is necessary to ensure that the physical rigid body and the virtual object fit together to ensure the performance of the virtual object in the game.

[0074] For virtual objects, when constructing virtual objects (the art model), artists can use an origin as a reference point for construction. Different virtual objects can correspond to different origins, and different virtual objects can correspond to different object coordinate systems. The present invention does not impose any restrictions on this.

[0075] In a specific implementation, the item parameters include at least the origin coordinates in the object coordinate system constructed based on the origin of the virtual object, the vertex distance between each vertex and the origin in the object coordinate system, and the coordinate axis angle between each vertex and the coordinate axis in the object coordinate system. The client can use the vertex distance and the coordinate axis angle to calculate the vertex coordinates of each vertex in the virtual object in the object coordinate system, and then create a physical rigid body that fits the virtual object based on the vertex coordinates, and combine the physical rigid body with the virtual object to obtain the corresponding virtual object model, so that the player can operate the virtual object model in the game.

[0076] It should be noted that for each virtual object, it corresponds to an origin and includes several vertices. Then, in the object coordinate system corresponding to the virtual object, the vertex distance between each vertex and the origin can be obtained in turn, and a line can be connected between the vertex and the origin to obtain the coordinate axis angle between the connecting line and the coordinate axis, so as to calculate the vertex coordinates of each vertex in the object coordinate system based on the vertex distance and the coordinate axis angle.

[0077] In a specific implementation, the coordinate axis angle may include the y-axis angle between the line between the vertex and the origin and the y-axis, and the z-axis angle between the line between the projection point of the vertex projected onto the plane formed by the x-axis and z-axis and the origin and the z-axis. For each vertex, the client may first obtain the first sine value and first cosine value corresponding to the y-axis angle corresponding to the vertex, as well as the second sine value and second cosine value corresponding to the z-axis angle, and then use the vertex distance, the first sine value and the second sine value to calculate the x-axis coordinate of the vertex in the object coordinate system, use the vertex distance and the first cosine value to calculate the y-axis coordinate of the vertex in the object coordinate system, and use the vertex distance, the first sine value and the second cosine value to calculate the z-axis coordinate of the vertex in the object coordinate system, thereby obtaining the vertex coordinates of the vertex in the object coordinate system.

[0078] In one example, referring to Figure 2 , shows a schematic diagram of the object coordinate system provided in an embodiment of the present invention, wherein the distance between the vertex and the origin o of the coordinate system can be defined as r, the angle between the vertex and the y-axis is defined as θ, and the angle between the projection point of the vertex onto the xoz plane and the z-axis is defined as ψ. According to the calculation formula of the three-dimensional coordinates, the coordinates of any vertex P on the virtual object can be obtained as: x = r sinθsinψ, y = r cosθ, z = r sinθcosψ.

[0079] After obtaining the vertex coordinates corresponding to each vertex on the virtual object, the vertex coordinates corresponding to each vertex can be passed into the physics engine corresponding to the game client to create an interface for a physical rigid body. The physics engine can then create an irregular polyhedron physical rigid body that fits the virtual object based on the vertex coordinates corresponding to each vertex. The physical rigid body can then be combined with the virtual object (using the virtual object as the appearance and the physical rigid body as the "filler content" to obtain a virtual object model that can be displayed in the game scene and supports player operations). By creating a model that fits the virtual object, it is possible to avoid situations such as the model sinking, penetrating, or floating in the air when collisions occur during the falling of items in the game, thereby improving the realism of the falling items and optimizing the performance effect.

[0080] Step 103: Obtain the drop point of the virtual object in the game scene sent by the server, and determine the motion parameters corresponding to the drop point;

[0081] While constructing the virtual object model corresponding to the virtual object, the client can also obtain the drop point of the virtual object in the game scene sent by the server and determine the motion parameters corresponding to the drop point, so as to control the virtual object model to perform the corresponding movement in the game scene according to the motion parameters. Optionally, for different drop points, different drop scenes have different corresponding drop points. For example, when it is a resource drop, the drop point can be the coordinates of the resource object in the game scene; when it is to kill the game boss or enemy player character, the drop point can be the coordinates of the game boss or enemy player character when they die in the game, etc. The above coordinates are based on the coordinates in the scene coordinate system corresponding to the game scene.

[0082] In a specific implementation, different clients receive the same drop point, which can be the target coordinate in the scene coordinate system. The client can use the target coordinate to calculate the random seed value for the virtual object, obtain the range of motion parameters corresponding to the virtual object, and then use the random seed value to calculate the motion parameters within the range of motion parameters. For the random seed value, different coordinates can generate different values. Since the drop point received by each client is the same, the generated random seed value is also the same. Specifically, considering that the movement of the virtual object model in the game scene involves the throwing force value, throwing direction and rotation speed, in the process of determining the throwing force value, throwing direction and rotation speed based on the random seed value, the range of the throwing force value, the angle of the throwing direction and the upper and lower limits of the rotation speed can be constrained, so that the client can use the random seed value to calculate the throwing force value, the throwing angle within the horizontal angle range and the rotation speed within the rotation speed range.

[0083] Among them, the throwing force value can be the force (unit: N) when the virtual object model is thrown from the drop point, the throwing direction can be the horizontal direction interval [0, 360°], and the rotation speed can be the rotation speed of the virtual object model when it is thrown, etc. For these motion parameter ranges, on the one hand, they can be set based on different virtual objects, and on the other hand, they can also be set according to actual needs in the game. Optionally, in order to improve the authenticity of the falling movement of the virtual object model, the client can obtain the corresponding motion parameter range based on the volume information of the virtual object. For example, the larger the volume, the greater the throwing force value, the lower the throwing direction, and the lower the rotation speed; the smaller the volume, the smaller the throwing force value, the higher the throwing direction, and the higher the rotation speed, etc. The present invention does not impose any restrictions on this.

[0084] In one example, in order to make the motion rules of the virtual object models of each client consistent, it is necessary to ensure that the input parameters of the projectile motion of the virtual object model: throwing force, throwing direction, rotation speed, etc. are consistent, and each input parameter is as random as possible. To this end, after obtaining the target coordinates corresponding to the drop point, the corresponding random seed value can be calculated based on the target coordinates. The random seed calculation formula is as follows: random seed seed = exit point pos.x*100 + exit point pos.y*10 + exit point pos.z. Since the drop point obtained by each client is consistent, the calculated random seed value is also consistent. Based on this calculated consistent random seed, the random force, throwing direction, and rotation speed are all consistent.

[0085] It should be noted that in addition to the throwing force value, the corresponding gravity value can also be obtained for the above-mentioned process of calculating motion parameters. The gravity value can ensure that the virtual object model's falling motion in the game scene is always downward and eventually comes to rest on the ground of the game scene. Specifically, the gravity value can be a fixed value that is greater than the throwing force value. Its corresponding direction is downward, that is, the negative direction of the y-axis in the scene coordinate system, while the throwing force value corresponds to the positive direction of the y-axis. When the projectile motion is triggered, the two forces are superimposed to ensure that the final acceleration in the vertical direction is a negative value, causing the dropped object to fall vertically. Without the guarantee of gravity, if the acceleration in the vertical direction is a positive value, the dropped object will not appear to be falling, but will instead fly upward, flying out of the scene faster and faster, which is inconsistent with the dropping of virtual items in the game.

[0086] Step 104 : Control the virtual object model to perform a corresponding falling motion with the falling point as a starting point according to the motion parameters.

[0087] In the specific implementation, after the client calculates the throwing force value, throwing direction and rotation speed corresponding to the virtual object, the client can control the virtual object model along the throwing angle according to the rotation speed and throwing force value to perform the corresponding dropping motion with the dropping point as the starting point. On the one hand, the client performs the motion trajectory calculation, which can effectively reduce the computing pressure of the server. On the other hand, based on the motion parameters determined based on the same drop point, the motion trajectory calculated by each client is the same, thereby ensuring that the dropping process of the same item in different clients is the same, and ensuring the synchronization of the item dropping motion trajectory in the game.

[0088] Based on the same projectile motion input parameters, each client achieves the same trajectory. After the virtual object model hits the ground or an inclined surface, the output of the physics engine simulation is consistent across all clients, ensuring consistent rebound motion input. This ensures a consistent trajectory in the next round of oblique projectile motion. This cycle repeats until the object stops, maintaining a consistent trajectory. This ensures that the irregular polyhedron falls with the same trajectory and position across all clients.

[0089] In an embodiment of the present invention, in a game, in an item drop scene, a game client can respond to an item drop instruction, determine a virtual object corresponding to the item drop instruction, and obtain item parameters corresponding to the virtual object. The virtual object corresponds to an object coordinate system, and the item parameters are parameters determined based on the object coordinate system. Then, based on the item parameters, the vertex coordinates of each vertex in the virtual object in the object coordinate system are determined, and a virtual object model corresponding to the vertex coordinates is constructed. By creating a model that fits the virtual object, it is possible to avoid the model from sinking, penetrating, floating, etc. when a collision occurs during the item drop process in the game, thereby improving the realism of the item drop. At the same time, the game client can obtain the drop point of the virtual object sent by the server in the game scene, determine the motion parameters corresponding to the drop point, and then control the virtual object model according to the motion parameters to perform the corresponding drop motion with the drop point as the starting point. On the one hand, the client performs the motion trajectory calculation, which can effectively reduce the computing pressure of the server. On the other hand, based on the motion parameters determined by the same drop point, the motion trajectory calculated by each client is the same, thereby ensuring that the drop process of the same item in different clients is the same, and ensuring the synchronization of the item drop motion trajectory in the game.

[0090] In order to help those skilled in the art better understand the technical solutions of the embodiments of the present invention, an example is given below to illustrate:

[0091] Assuming that the virtual object is a tetrahedron crystal, in order to make the tetrahedron crystal visible and operable in the game, and to have corresponding physical collisions, it is necessary to add a corresponding physical rigid body to the tetrahedron crystal so that it can be supported by the ground of the game scene.

[0092] In practice, when an item drop is triggered, the server can notify each participating client to create a drop item. At the same time, the server can also generate the drop's launch point (pos), which is a three-dimensional vector (x, y, z). This launch point is also synchronized to each client along with the signal to create the drop item.

[0093] For the client, it can first build the object rigid body corresponding to the dropped object, refer to Figure 3, shows a schematic diagram of a virtual object provided in an embodiment of the present invention. When the dropped object is a tetrahedron crystal, and the origin of the tetrahedron crystal is located at the bottom surface and there is exactly one vertex located on the y-axis, assuming that the edge length is a, the coordinates of one of the vertices can be obtained as (0, 0), then for the three vertices on the xoz plane, since the base is an equilateral triangle, that is, the angle is 60 degrees, then the remaining three points are obtained:

[0094]

[0095]

[0096]

[0097] Then the corresponding vertex data is:

[0098]

[0099] By replacing the edge length with the actual triangle block data, we can get a perfectly fitting tetrahedron crystal physical rigid body:

[0100]

[0101] After obtaining the vertex coordinates corresponding to each vertex of the virtual object through the above process, the vertex coordinates can be input into the physics engine corresponding to the game to generate a physical rigid body, and the physical rigid body can be combined with the dropped object to obtain the corresponding dropped object model (i.e., tetrahedral crystal model).

[0102] Once the tetrahedron model is constructed, it is positioned at the exit point, ready to execute the corresponding projectile motion according to the input parameters, such as force, direction of throw, and speed. Regarding the motion parameters, to ensure consistent motion rules for all dropped objects across clients, the input parameters for the projectile motion—force, direction of throw, and speed—must be consistent. Each input parameter must be as random as possible. The random seed calculation formula is: random seed = exit point pos.x * 100 + exit point pos.y * 10 + exit point pos.z. Since each client receives the same exit point, the calculated random seed value is also consistent. Based on this consistent calculated random seed, the random force, direction of throw, and speed are all consistent.

[0103] Specifically, you can first define the ranges for force, direction, and speed. For example, the force range is [0, 10] Newtons, the direction is defined as the horizontal range [0, 360] degrees, and the speed range is [0, 5] m / s. The resulting random force, direction, and speed are all guaranteed to fall within the corresponding ranges. The values ​​obtained vary depending on the random seed value. For example, if the random seed value is 13674, then according to the algorithm's mapping, the resulting force is 5.73 Newtons, the angle is 132 degrees, and the speed is 2.81 m / s.

[0104] After the client calculates the throwing force value, throwing direction and rotation speed corresponding to the virtual object, the client can control the virtual object model along the throwing angle according to the rotation speed and throwing force value to perform the corresponding dropping motion with the dropping point as the starting point. On the one hand, the client performs the motion trajectory calculation, which can effectively reduce the computing pressure of the server. On the other hand, based on the motion parameters determined by the same drop point, the motion trajectory calculated by each client is the same, thereby ensuring that the dropping process of the same item in different clients is the same, and ensuring the synchronization of the item dropping motion trajectory in the game.

It will be understood by those skilled in the art that the electronic device structure involved in the embodiments of the present invention does not constitute a limitation on the electronic device, and the electronic device may include more or fewer components than shown, or combine certain components, or arrange the components differently. In the embodiments of the present invention, the electronic device includes but is not limited to a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted terminal, a wearable device, and a pedometer.

[0133] It should be understood that in this embodiment of the present invention, the RF unit 501 can be used to receive and transmit signals during information transmission or calls.

[0135] The audio output unit 503 can convert audio data received by the RF unit 501 or the network module 502 or stored in the memory 509 into an audio signal and output it as sound. In addition, the audio output unit 503 can also provide audio output related to a specific function performed by the electronic device 500 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 503 includes a speaker, a buzzer, a receiver, etc.

[0136] The input unit 504 is used to receive audio or video signals. The input unit 504 may include a graphics processing unit (GPU) 5041 and a microphone 5042. The graphics processor 5041 processes image data of a still picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The processed image frames can be displayed on the display unit 506. The image frames processed by the graphics processor 5041 can be stored in the memory 509 (or other storage medium) or transmitted via the radio frequency unit 501 or the network module 502. The microphone 5042 can receive sound and process such sound into audio data. The processed audio data can be converted into a format that can be sent to a mobile communication base station via the radio frequency unit 501 in the case of a telephone call mode.

[0137] The electronic device 500 also includes at least one sensor 505, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor includes an ambient light sensor and a proximity sensor, wherein the ambient light sensor can adjust the brightness of the display panel 5061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 5061 and / or the backlight when the electronic device 500 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary.

The touch panel 5071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using any suitable object or accessory such as a finger, stylus, etc. on or near the touch panel 5071). The touch panel 5071 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch direction and detects the signal caused by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 510, which receives and executes the command sent by the processor 510.

[0143] The processor 510 is the control center of the electronic device. It connects the various components of the electronic device using various interfaces and circuits. By running or executing software programs and / or modules stored in the memory 509 and accessing data stored in the memory 509, it performs various functions of the electronic device and processes data, thereby monitoring the electronic device as a whole. The processor 510 may include one or more processing units; preferably, the processor 510 may integrate an application processor and a modem processor, wherein the application processor primarily processes the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into the processor 510.

[0144] The electronic device 500 may also include a power supply 511 (such as a battery) to supply power to each component. Preferably, the power supply 511 may be logically connected to the processor 510 through a power management system, thereby managing functions such as charging, discharging, and power consumption through the power management system.
