Technical Field

The present invention relates to the field of information processing technologies, and in particular, to a method and an apparatus for correcting a carrier position, a second client, and an electronic device.

Background

The requirements of users on game pictures and virtual reality effects are more and more strong, which leads to a larger scene design of the game. With the development and production level of the game being higher and higher, the scene of the game is larger and larger, and the details are finer and finer. Making a fine game brings a better game experience to the player. However, a large scene and a large amount of details occupy a large amount of resources, the performance requirement of a machine for running a game is high, and if the performance of the machine cannot meet the requirement, a phenomenon of stuttering is likely to occur, so that the game experience of a user is poor. For example, if a network game in which multiple persons participate together, especially a network game with 2D and 3D effects, is run on a mobile phone, if the resource occupation of the game on the mobile phone is too high, the mobile phone will be hot, the game will be jammed, and delay will occur, which indirectly causes the loss of the user, and the game that wants to achieve the same effect as the PC end at the mobile phone end is limited by the hardware of the mobile phone and the network, so that the problem of occupying hardware resources is more and more urgent to solve by improving the design scheme of software.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following describes a vehicle physical simulation method, a vehicle physical simulation system, a client, an electronic device, and a server according to embodiments of the present invention with reference to the drawings.

Fig. 1 is a block diagram of a vehicle physical simulation system according to an embodiment of the present invention.

As shown in fig. 1, the vehicle physical simulation system includes a client 100 and a server 200.

Among other things, the client 100 may include a first client 110 and a second client 120.

The definitions of the terms in the following embodiments will be briefly described below.

A client installed in an application in an electronic device. The client may be an electronic device such as a mobile phone, a tablet computer, a notebook computer, a virtual reality device, an augmented reality device, a mixed reality device, and the like, which is not limited specifically here.

And the server provides equipment for computing and network communication service. The server may be a single device or a cluster of multiple devices, and is not limited herein.

And the first role uses the virtual character corresponding to the first user of the application in the application.

And the second role is a virtual character corresponding to any user in the application except the first role.

The first user controls the first role through the first client.

The second user controls the second role through the second client.

The vehicle, the vehicle in which the user using the application can drive, such as an airplane, an automobile, a bicycle, a motorcycle, a yacht, a ship, a balance car, etc., is not particularly limited herein.

The physical simulation refers to the simulation of the physical state change of the real vehicle. If the vehicle is a jeep, the rotation of tires of the jeep, the bump generated when the vehicle runs on an uneven road surface and the like can be simulated. When the jeep runs on uneven ground, the four groups of suspension springs can stretch out and draw back to different degrees to support the car body, and in the process, the car body can generate reciprocating shaking, tilting and other dynamic effects. The jeep physical simulation is briefly described as follows:

1. simulating the rotation speed of an engine and enabling a tire to rotate at a certain speed through a gearbox at a certain rotation speed ratio;

2. the contact point between the tyre and the ground has friction force which determines whether the tyre can slip or not and the thrust force applied to the vehicle by the tyre;

3. the thrust exerted by the tires on the vehicle moves the vehicle;

4. when the vehicle moves on uneven ground, the four groups of suspension springs can stretch out and draw back to different degrees to support the vehicle body, and the vehicle body can shake and incline in a reciprocating manner in the process.

The visual range refers to a visual range of a virtual character in an application by a user using the application, and refers to a visual range of the virtual character in an application scene. Such as the field of view of the first character, the field of view of the second character. When the virtual character looks straight ahead, the angles observable from left to right and from top to bottom of the eyes are limited, so that the visual range of the virtual character is an approximately conical area, and the range is represented by an aggregation area of three-dimensional coordinates in an application map.

Vehicle position, the three-dimensional coordinate position of the vehicle within the application scene (map).

The vehicle control comprises a driving control, a taking control, a leaving control, an accelerating control, a decelerating control, a direction control and the like. The user controls the vehicle by touching or sliding the vehicle control, such as driving the vehicle, riding the vehicle, leaving the vehicle, accelerating, decelerating, advancing, backing, moving left, moving right, and the like.

In an embodiment of the present invention, when the first client 110 detects that the first character triggers the vehicle control, the first client 110 may obtain operation information of the first user on the vehicle and position information of the vehicle, and send the operation information of the first user on the vehicle and the position information of the vehicle to the server 200. The server 200 may receive the operation information of the first user on the vehicle and the position information of the vehicle sent by the first client, and synchronize the operation information of the first user on the vehicle and the position information of the vehicle to the second client 120. The second client 120 receives the operation information of the first user on the vehicle and the position information of the vehicle sent by the server, and performs physical simulation on the vehicle according to the operation information of the first user on the vehicle and the position information of the vehicle in the second client 120.

Specifically, the second client 120 determines whether the vehicle is within the range of the line of sight of the second character. And if the carrier is not in the range of the visual distance of the second role, not starting physical simulation of the carrier, and if the carrier is in the range of the visual distance of the second role, carrying out physical simulation on the carrier according to the operation information of the first user on the carrier and the position information of the carrier, which are sent by the server, until the carrier is stable or leaves the range of the visual distance of the second role.

This embodiment describes a case where the vehicle is manipulated by the first character as viewed from the perspective of the second character. The first role refers to a role of controlling the vehicle, and the second role refers to a role of observing the vehicle. Specifically, the server stores data related to the application, including position information of a vehicle operated by the first character and operation information of the vehicle. The server establishes communication with the plurality of clients, and each client acquires the position information of the role using the client and the control information of the role on the carrier and sends the position information to the server. After receiving the information, the server synchronizes the information to each client, so that each client comprises the position information of the role corresponding to all the clients and the control information of the role on the carrier after acquiring the synchronization information. The second client obtains the control information of the first client to the carrier and the real-time carrier position information driven by the first client, which are sent by the server. The carrier position information may be sent by the server at a frequency of 100 ms/time. If the vehicle driven by the first character is observed in the sight distance range of the second character, the second client can continuously acquire the position information (three-dimensional coordinates) of the vehicle driven by the first character and detect whether the position information changes. If the position information of the vehicle continuously changes, the vehicle can be determined to be in a moving state. In the second client, the physical simulation of the carrier can be continued by utilizing the control information of the first user on the carrier. It should be appreciated that the second client, when not receiving the most up-to-date information, uses the last received information to perform the physical simulation. If the vehicle position does not change continuously, the vehicle can be determined to be stable, and the second client can stop the physical simulation of the vehicle. Taking an automobile vehicle as an example, the first user triggers a driving or riding control, and the corresponding first character enters the automobile vehicle. The first client carries out physical simulation on the automobile carrier, when a first character enters the automobile carrier, because the first character has weight, four groups of suspension springs of the automobile carrier bear the pressure of the gravity of the first character and contract to support the automobile body, and meanwhile, the automobile body can generate the visual effect of physical change processes such as reciprocating shaking and the like. The first client records operation information of the first user triggering the driving or riding control and sends the information to the server, and the server synchronizes the operation information of the first user triggering the driving or riding control to the second client. In the visual range of the second role, the second client receives operation information of a control triggered to drive or ride by the first user on the automobile carrier and position information of the automobile carrier sent by the server, and performs physical simulation on the carrier driven by the first user according to the information, so that the second user can observe the visual effect of physical change processes such as reciprocating shaking and the like generated by the first user driving or riding the automobile carrier body in the visual range of the second role, and the second client performs physical simulation on the operation information simulation pair of the first client by using the first role, so that the visual effect of the whole physical change process is closer to reality. Similarly, after a first user triggers a driving control and enters the vehicle, a vehicle control at least comprising an acceleration control is displayed on an interactive interface of the first user, the first user triggers the acceleration control, first user operation information is sent to equipment by first equipment, second equipment receives the information from a server, the operation information of the first user triggering the acceleration control carries out physical simulation on the vehicle controlled by the first user, and then a second role observes the visual effect of the physical change process of the accelerated advance of the first role driving vehicle; if the first user triggers the ride control, the acceleration control and the deceleration control are not displayed on the interactive interface of the first user. After the first user triggers the driving or riding control, the first character triggers the leaving control, and then the second character can also observe the vibration effect of the suspension spring when the first character leaves the vehicle. It should be understood that the physical simulation effect generated by the first user-triggered control occurs within the visual range of a second character that observes the visual effect of the physical change process physically simulated by the second device. If the client is not within the range of the visual range, the second role will not observe the visual effect of the physical state change process, that is, the corresponding second client will not start the physical simulation.

In order to simulate the virtual character more truly, some more realistic setting is made, for example, the virtual character can see 500 meters farthest in a sunny day; in foggy days, the virtual character can see 300 meters farthest. That is, the range of viewing distances may vary with weather.

In another embodiment of the present invention, when the first client 110 detects that the first character triggers the vehicle control, the first client performs a physical simulation on the vehicle according to the operation information of the vehicle and the position information of the vehicle sent by the server by the first user. This embodiment describes the situation of the first character perspective when the first character drives the vehicle. For example, the vehicle enters the field of view of the first character, and the user may select to touch a ride control in the interactive interface, thereby controlling the entry of the first character into the vehicle. The user can control driving of the vehicle and perform physical simulation on the vehicle, such as vehicle acceleration, vehicle deceleration and the like, on the acceleration control, the deceleration control and the like (inputting an instruction on the sliding direction or the pressure of the acceleration control and the deceleration control and inputting an instruction on the sliding direction or the sliding angle of the direction control) on the touch interactive interface.

The scheme aims to simulate real driving experience as much as possible and improve the operability of application and the operation enthusiasm of users.

In another embodiment of the present invention, the first client 110 is further configured to determine whether the vehicle is within the range of sight of the first character when the first client detects that the first character triggers the vehicle to leave the control. If the vehicle is not within the range of the line of sight of the first character, the physical simulation of the vehicle is not started. And if the carrier is within the range of the sight distance of the first role, further judging whether the carrier is stable. If the carrier is stable, stopping performing physical simulation on the carrier; and if the vehicle is not stable, performing physical simulation on the vehicle until the vehicle is stable or leaves the range of the visual distance of the first character. This embodiment describes the case where the first character leaves the carrier.

Specifically, the first client receives an input instruction of clicking a departure control in the interactive interface by the first user, and the first character immediately departs from the driven vehicle. The first client continuously acquires the carrier position and whether the carrier position changes or not. If the position of the carrier does not continuously change, the carrier can be determined to be stable, the first client stops physical simulation of the carrier, and the position of the carrier in stable stopping is sent to the server. If the vehicle position continues to change, it may be determined that the vehicle is still moving. The first client continues to perform physical simulation on the carrier. Further, the first client continuously acquires the carrier position and judges whether the carrier position is within the sight distance range of the first role. If the acquired carrier position is not within the visual distance range of the first role, the physical simulation of the carrier can be stopped in the first client, the carrier position is continuously acquired until the carrier is stably stopped, and the position after the stabilization is sent to the server. If the acquired position is within the range of the first character, the first client continues to physically simulate the vehicle until the vehicle is stabilized or the current position of the vehicle is away from the range of the first character. The first client continuously obtains the first role and the real-time carrier position driven by the first role and sends the position to the server.

In the above embodiments, the physical simulation is selectively turned off for the vehicle instead of continuously performing the physical simulation, which optimizes the device resources, improves the performance of the resource optimization device, prevents the stuck phenomenon, and improves the simulated driving experience.

In another embodiment of the present invention, the first client 110 and/or the second client 120 may further obtain a topographic feature of the vehicle when the vehicle is generated by the server 200, and perform a physical simulation on the vehicle generated by the server according to the topographic feature of the vehicle. This embodiment describes the case when the server initializes scene information and generates a vehicle.

Specifically, all the clients can obtain the application start instruction sent by the server, and the interactive interface in the waiting stage in the client is switched to the application scene interactive interface. Further (simultaneously), all the clients acquire the carrier generation instruction sent by the server. The vehicle generation instruction comprises each vehicle type required to be generated in an application scene (map) and a vehicle position appearing in the application scene. Various different types of carriers can be preset in the server, and the application scenes of the different types of carriers are different. For example, an application map is generally composed of three areas, land, water and air. The automobile, the bicycle and the balance car are suitable for land traffic, the yacht and the steamship are suitable for water traffic, the airplane is suitable for air traffic, the land traffic is parked on land for users to carry out land traffic, the water traffic is parked in a water area for users to carry out water traffic, and the airplane is parked on land for users to carry out air traffic after taking off from the ground. The client obtains an application starting instruction sent by the server, and further (simultaneously) the client obtains the type of the carrier needing to be generated in each area in the map and the three-dimensional coordinate position of the carrier in each area range in the map. After the client side obtains the carrier generation instruction generated by the server, 3D modeling can be carried out at the corresponding position in the map randomly to generate a corresponding carrier. Further, each client generates a vehicle at a three-dimensional coordinate position with a certain height above the ground and the water surface instead of generating the vehicle at the three-dimensional coordinate position of the ground and the water surface directly. The initial generating position of the carrier is higher than the ground or the water surface by a certain height, the carrier generated by the client is influenced by virtual gravity in application and falls down and contacts with fixed scenes such as the ground, buildings, trees, water areas and the like in application scenes after falling down so as to generate physical state change, so that the client can perform physical simulation to simulate the physical state change of the carrier until the position of the carrier is not changed any more, the carrier is considered to be stopped stably, and the client stops the physical simulation. The method comprises the steps of setting a client to generate a carrier position and carrying out physical simulation on a carrier until the carrier is stable, and is used for avoiding the visual effect that a land vehicle stops on a steep slope on a mountain, wherein a fixed scene possibly caused by a non-planar fixed scene is superposed with a carrier model or a physical phenomenon is violated in the prior art when the carrier model is attached to the fixed scene model. Through the physical simulation of the client to the carrier, the carrier is changed from a physical state to final stable halt in each area, and the carrier is closer to the physical phenomenon in a real environment, so that the reality sense of application is improved.

In addition, in another embodiment of the present invention, the second client 120 may also correct the position information of the vehicle. This embodiment describes a case where network communication between the second client 120 and the server 200 is delayed or lost.

Specifically, the position of the vehicle driven by the first user in the second client deviates from the position of the vehicle sent by the first client stored in the server, and at this time, the server sends the stored position of the vehicle sent by the first client to the second client. The second client can receive the position information of the first role driving carrier and can correct the position of the first role driving carrier in the second role sight distance range.

Under the above situation, by forcibly correcting the position of the vehicle, the second character can observe that the vehicle driven by the first character generates transient movement or flickering phenomenon, which affects the experience of the second user.

In order to avoid or reduce the transient or flicker phenomenon occurring in the process of correcting the position of the vehicle, in another embodiment, the second client may perform anti-flicker processing on the position information of the corrected vehicle. The method comprises the following steps:

step 1, assuming that the position of the carrier M before correction is A [ xa, ya, za ], and the position after correction is B [ xb, yb, zb ];

and 2, the second client receives the carrier coordinate position information sent by the server, simultaneously hides the carrier, and sets a carrier N which is only the same as the appearance model of the carrier M at the position A. The second client only controls the carrier N to move along with the carrier M and keeps the coordinate positions of the carrier N and the carrier M relatively static, and does not physically simulate the carrier N. During the moving process, the relative offset vector of the coordinate positions of the carrier M and the carrier N is C [ xc, yc, zc ], where C is B-a. At the moment, the second user can only see the carrier N with the same appearance model as the carrier M, so that the situation of instantaneous carrier movement does not occur visually;

step 3, the carrier M continues to move, and the carrier N moves together with the carrier M due to relative rest;

step 4, linearly reducing the relative offset vector C to 0 within N seconds, namely translating the false carrier N to the position of the real carrier M within N seconds;

and 5, hiding the false carrier N and displaying the real carrier M when the C is changed to be 0.

The purpose of adopting the scheme is that the carrier M is a real carrier, the second client performs physical simulation on the carrier M in real time, the carrier N without collision can be used when the carrier M is directly translated, the carrier N does not need to perform physical simulation, the carrier N does not collide with the scene in the client when the carrier N is directly translated, and the phenomenon of instant shift or flicker of the carrier M can be weakened by translating the carrier N.

In the carrier physical simulation system of the embodiment of the invention, under the condition that the first client detects that the first role triggers the carrier control, the first client acquires the carrier operation information and the carrier position information of the first user and sends the carrier operation information and the carrier position information of the first user to the server, the server receives the carrier operation information and the carrier position information of the first user sent by the first client and synchronizes the carrier operation information and the carrier position information of the first user to the second client, the second client receives the carrier operation information and the carrier position information of the first user sent by the server, and in the second client, the carrier is physically simulated according to the carrier operation information and the carrier position information of the first user, so that the equipment resource is optimized, and the performance of the resource optimization device is improved, prevent the phenomenon of blocking, promote simulation driving and experience.

In order to implement the above embodiments, the present invention further provides a physical simulation method for a vehicle.

Fig. 2 is a flowchart of a vehicle physical simulation method according to an embodiment of the invention.

As shown in fig. 2, the vehicle physical simulation method applied to the client includes the following steps:

step 201, when the first client detects that the first character triggers the vehicle control, the first client obtains operation information of the first user on the vehicle and position information of the vehicle, and sends the operation information of the first user on the vehicle and the position information of the vehicle to the server, so that the server receives the operation information of the first user on the vehicle and the position information of the vehicle sent by the first client, and synchronizes the operation information of the first user on the vehicle and the position information of the vehicle to the second client.

The client comprises a first client and a second client, the first user controls the first role through the first client, and the second user controls the second role through the second client.

Step 202, the second client receives the operation information of the first user on the vehicle and the position information of the vehicle sent by the server, and performs physical simulation on the vehicle according to the operation information of the first user on the vehicle and the position information of the vehicle in the second client.

Specifically, the second client determines whether the carrier is in the range of the line of sight of the second role, if the carrier is not in the range of the line of sight of the second role, the physical simulation of the carrier is not started, and if the carrier is in the range of the line of sight of the second role, the physical simulation of the carrier is performed according to the operation information of the first user on the carrier and the position information of the carrier, which are sent by the server, until the carrier is stable or leaves the range of the line of sight of the second role.

The present embodiment describes a situation that the first character is observed from the perspective of the second character to control the vehicle. The first role refers to a role of controlling the vehicle, and the second role refers to a role of observing the vehicle. Specifically, the server stores data related to the application, including position information of a vehicle operated by the first character and operation information of the vehicle. The server establishes communication with the plurality of clients, and each client acquires the position information of the role using the client and the control information of the role on the carrier and sends the position information to the server. After receiving the information, the server synchronizes the information to each client, so that each client comprises the position information of the role corresponding to all the clients and the control information of the role on the carrier after acquiring the synchronization information. The second client obtains the control information of the first client to the carrier and the real-time carrier position information driven by the first client, which are sent by the server. The carrier position information may be sent by the server at a frequency of 100 ms/time. If the vehicle driven by the first character is observed in the sight distance range of the second character, the second client can continuously acquire the position information (three-dimensional coordinates) of the vehicle driven by the first character and detect whether the position information changes. If the position information of the vehicle continuously changes, the vehicle can be determined to be in a moving state. In the second client, the physical simulation of the carrier can be continued by utilizing the control information of the first user on the carrier. It should be appreciated that the second client, when not receiving the most up-to-date information, uses the last received information to perform the physical simulation. If the vehicle position does not change continuously, the vehicle can be determined to be stable, and the second client can stop the physical simulation of the vehicle. Taking an automobile vehicle as an example, the first user triggers a driving or riding control, and the corresponding first character enters the automobile vehicle. The first client carries out physical simulation on the automobile carrier, when a first character enters the automobile carrier, because the first character has weight, four groups of suspension springs of the automobile carrier bear the pressure of the gravity of the first character and contract to support the automobile body, and meanwhile, the automobile body can generate the visual effect of physical change processes such as reciprocating shaking and the like. The first client records operation information of the first user triggering the driving or riding control and sends the information to the server, and the server synchronizes the operation information of the first user triggering the driving or riding control to the second client. In the visual range of the second role, the second client receives operation information of a control triggered to drive or ride by the first user on the automobile carrier and position information of the automobile carrier sent by the server, and performs physical simulation on the carrier driven by the first user according to the information, so that the second user can observe the visual effect of physical change processes such as reciprocating shaking and the like generated by the first user driving or riding the automobile carrier body in the visual range of the second role, and the second client performs physical simulation on the operation information simulation pair of the first client by using the first role, so that the visual effect of the whole physical change process is closer to reality. Similarly, after a first user triggers a driving control and enters the vehicle, a vehicle control at least comprising an acceleration control is displayed on an interactive interface of the first user, the first user triggers the acceleration control, first user operation information is sent to equipment by first equipment, second equipment receives the information from a server, the operation information of the first user triggering the acceleration control carries out physical simulation on the vehicle controlled by the first user, and then a second role observes the visual effect of the physical change process of the accelerated advance of the first role driving vehicle; if the first user triggers the ride control, the acceleration control and the deceleration control are not displayed on the interactive interface of the first user. After the first user triggers the driving or riding control, the first character triggers the leaving control, and then the second character can also observe the vibration effect of the suspension spring when the first character leaves the vehicle. It should be understood that the physical simulation effect generated by the first user-triggered control occurs within the visual range of a second character that observes the visual effect of the physical change process physically simulated by the second device. If the client is not within the range of the visual range, the second role will not observe the visual effect of the physical state change process, that is, the corresponding second client will not start the physical simulation.

The second client receives the location information of the vehicle driven by the first user and the location information of the vehicle driven by the first user in the first client may have a deviation due to network delay and the like.

The server continuously updates the position information of the carrier driven by the first user sent by the first client, and the second client corrects the current position information of the carrier driven by the first user after receiving the information. Specifically, the server sends the saved carrier position driven by the first user sent by the first client to the second client. The second client can receive the position information of the first role driving carrier and correct the position of the first role driving carrier in the second role sight distance range.

After the position information of the vehicle driven by the first user is corrected, a phenomenon such as flicker may occur, so the second client needs to perform anti-flicker processing on the corrected position information of the vehicle. In order to avoid or reduce the transient or flicker phenomenon occurring in the process of correcting the position of the vehicle, in another embodiment, the second client may perform anti-flicker processing on the position information of the corrected vehicle. The method comprises the following steps:

In another embodiment of the present invention, as shown in fig. 3, the method further comprises:

step 203, when the first client detects that the first character triggers the vehicle control, operation information of the first character vehicle is obtained in the first client, and the vehicle is physically simulated.

This embodiment describes the situation of the first character perspective when the first character drives the vehicle. For example, the vehicle enters the field of view of the first character, and the user may select to touch a ride control in the interactive interface, thereby controlling the entry of the first character into the vehicle. The user can control driving of the vehicle and perform physical simulation on the vehicle, such as vehicle acceleration, vehicle deceleration and the like, on the acceleration control, the deceleration control and the like (inputting an instruction on the sliding direction or the pressure of the acceleration control and the deceleration control and inputting an instruction on the sliding direction or the sliding angle of the direction control) on the touch interactive interface.

In yet another embodiment of the present invention, as shown in fig. 4, the method further comprises:

step 204, when the first client detects that the first character triggers the carrier to leave the control, the first client determines whether the carrier is within the range of the visual range of the first character.

In step 205, if the vehicle is not within the range of the line of sight of the first character, the physical simulation of the vehicle is not started.

In step 206, if the vehicle is within the range of the first role, it is further determined whether the vehicle is stationary.

Step 207, if the vehicle is stable, stopping performing the physical simulation on the vehicle.

And step 208, if the vehicle is not stable, performing physical simulation on the vehicle until the vehicle is stable or leaves the range of the visual distance of the first role.

In yet another embodiment of the present invention, as shown in fig. 5, the method further comprises:

and 209, the first client and/or the second client acquires the topographic characteristics of the carrier when the carrier is generated by the server, and performs physical simulation on the carrier generated by the server according to the topographic characteristics of the carrier.

The present embodiment describes a case when the server initializes scene information and generates a vehicle.

The carrier physical simulation method of the embodiment of the invention comprises the steps that under the condition that a first client detects that a first role triggers a carrier control, the first client obtains operation information of a first user on a carrier and position information of the carrier and sends the operation information of the first user on the carrier and the position information of the carrier to a server, the server receives the operation information of the first user on the carrier and the position information of the carrier sent by the first client and synchronizes the operation information of the first user on the carrier and the position information of the carrier to a second client, the second client receives the operation information of the first user on the carrier and the position information of the carrier sent by the server, and in the second client, the carrier is physically simulated according to the operation information of the first user on the carrier and the position information of the carrier, so that equipment resources are optimized, and the performance of a resource optimization device is improved, prevent the phenomenon of blocking, promote simulation driving and experience.
