Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a method and device for detecting a virtual object, a storage medium, and an electronic device. Background Art

[0002] In a virtual game scene, the player controls the virtual object in the game scene on the client side, so that the position of the virtual object in the game screen changes. In a massively multiplayer online game, the player performs a trigger operation in the main client to move the virtual object from a first position to a second position, and synchronizes the movement information of the virtual object to the server. The movement information of the virtual object is broadcasted to other clients online at the same time through the server, so that the virtual object that is already in the second position after the move is displayed in other clients.

[0003] In the process of synchronizing the movement information to the server, there may be a problem of intentionally tampering with the parameters in the movement information package. In order to avoid this problem, before broadcasting the movement information to other clients, the server usually predicts the average movement speed of the virtual object from the first position to the second position based on the movement information. By comparing the predicted average movement speed with the preset average speed threshold, it is determined whether the movement speed of the virtual object is abnormal.

[0004] However, the above scheme predicts the average speed mainly based on the time when the server receives the mobile data packet. Although it ensures that the average speed of the vehicle on the server will never exceed the set upper limit, there is a high misjudgment rate. For example, when the network conditions on the main end are poor, the time difference between the mobile data packet 1 sent by the virtual object at the first position and the mobile data packet 2 sent when the virtual object moves to the second position and arriving at the server may be compressed or extended, resulting in the mobile average speed predicted by the server being larger or smaller than the normal predicted speed.

[0005] In this case, the comparison between the average speed predicted by the server and the preset average speed threshold value will inevitably lead to inaccurate detection results for detecting whether the moving speed of the virtual object is abnormal, thus causing a technical problem of low accuracy in the detection process of the virtual object.

[0006] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0053] According to one aspect of the embodiments of the present application, a method for detecting a virtual object is provided. As an optional implementation, the method for detecting a virtual object may be applied to, but is not limited to, Figure 1 The application scenario shown in Figure 1In the application scenario shown, the terminal device 102 may, but is not limited to, communicate with the server 106 via the network 104, and the server 106 may, but is not limited to, perform operations on the database 108, such as write data operations or read data operations. The terminal device 102 may, but is not limited to, include a human-computer interaction screen, a processor, and a memory. The human-computer interaction screen may, but is not limited to, be used to display a picture of a virtual object on the terminal device 102 being moved to a second position, a detection result of a virtual object, etc. The processor may, but is not limited to, be used to respond to the human-computer interaction operation, perform a corresponding operation, or generate a corresponding instruction, and send the generated instruction to the server 106. The memory is used to store relevant processing data, such as the first movement information, the second movement information, and the first prediction time, etc.

[0054] As an optional method, the following steps in the method for detecting a virtual object may be performed on the server 106: Step S102, obtaining first movement information and second movement information of the virtual object sent by the first client to the server, wherein the first movement information includes a first predicted time and a first coordinate, the first predicted time indicates the predicted time when the server receives the first movement information, and the first coordinate indicates the first position of the virtual object in the game scene, and the second movement information includes a second predicted time and a second coordinate, the second predicted time indicates the predicted time when the server receives the second movement information, and the second coordinate indicates the second position when the virtual object moves from the first position to the second position in the game scene; Step S104, determining the predicted average speed of the virtual object in the historical movement process according to the target distance and the target predicted time difference, wherein the target distance is the distance between the first coordinate and the second coordinate, and the target predicted time difference is the time difference obtained by subtracting the first predicted time from the second predicted time; Step S106, determining that there is an abnormality in the movement speed of the virtual object when at least one of the predicted average speed, the first predicted time, and the second predicted time does not meet the preset conditions.

[0055] In the above manner, the first mobile information and the second mobile information sent by the first client to the server at a preset time interval respectively include the first predicted time when the server receives the first mobile information and the second predicted time when the server receives the second mobile information. The server determines the target distance and the target predicted time difference based on the first mobile information and the second mobile information, calculates the predicted average speed of the virtual object in the historical movement process, and then judges whether there is an abnormality in the movement speed of the virtual object based on the predicted average speed, the first predicted time and the second predicted time. In other words, by synchronizing the first client and the server, a timestamp is added to the mobile information, so that the server can calculate a more accurate predicted average speed, thereby obtaining a more accurate detection result based on the predicted average speed, reducing the misjudgment rate, and achieving the technical effect of improving the accuracy of the detection results of the virtual object.

[0056] In order to solve the problem of low accuracy in the detection of virtual objects, a method for detecting virtual objects is proposed in an embodiment of the present application. Figure 2 : is a flowchart of a method for detecting a virtual object according to an embodiment of the present application, the process comprising the following steps:

[0057] Step S202, obtaining first movement information and second movement information of the virtual object sent by the first client to the server, wherein the first movement information includes a first prediction time and a first coordinate, the first prediction time indicates the prediction time when the server receives the first movement information, and the first coordinate indicates the first position of the virtual object in the game scene, and the second movement information includes a second prediction time and a second coordinate, the second prediction time indicates the prediction time when the server receives the second movement information, and the second coordinate indicates the second position when the virtual object moves from the first position to the second position in the game scene;

[0058] Step S204, determining a predicted average speed of the virtual object in the historical movement process according to the target distance and the target predicted time difference, wherein the target distance is the distance between the first coordinate and the second coordinate, and the target predicted time difference is the time difference obtained by subtracting the first predicted time from the second predicted time;

[0059] Step S206: When at least one of the predicted average speed, the first predicted time, and the second predicted time does not satisfy a preset condition, it is determined that there is an abnormality in the moving speed of the virtual object.

[0060] The technical solution in the embodiments of the present application can be applied to, but is not limited to, massively multiplayer online game scenarios. In this type of game scenario, when player 1 moves a virtual object from a first position to a second position by executing a trigger operation, it is necessary to broadcast the movement status of the virtual object in the first client where the player is located to a third party, and display the virtual object moved to the second position on the third party.

[0061] The third party may refer to, but is not limited to, a display platform for third-party players. The so-called third-party players may refer to, but are not limited to, players in the same game as player 1, for example, multiple players in the same camp and multiple players in different camps.

[0062] To facilitate understanding, first Figure 5 The overall schematic diagram of the server detecting the moving speed of the virtual object based on the time verification method is introduced.

[0063] like Figure 5 As shown, it is assumed that at moment C1, the first client sends the first movement information to the server, wherein the first movement information includes the predicted time when the server receives the first movement information and the first coordinates of the first position of the virtual object in the display screen of the first client at moment C1; at moment S1, the server receives the first movement information, wherein moment S1 is the time when the server actually receives the first movement information.

[0064] At moment C2, the first client sends second movement information to the server, wherein the second movement information includes the predicted time when the server receives the second movement information and the second coordinates of the second position of the virtual object in the display screen of the first client at moment C2; at moment S2, the server receives the second movement information, wherein moment S2 is the time when the server actually receives the second movement information.

[0065] Since the first predicted time included in the first mobile information does not take into account the network delay time caused by network fluctuations, nor the time offset of the first client itself, the first predicted time is earlier than the S1 time when the server actually receives the first mobile information. Similarly, the second predicted time is earlier than the S2 time when the server actually receives the second mobile information.

[0066] The server calculates the target distance between the first position and the second position based on the received first coordinates and the second coordinates, calculates the target prediction time difference between the first prediction time and the second prediction time, and then calculates the predicted average speed of the virtual object in the process of moving from the first position to the second position.

[0067] It is determined whether each of the predicted average speed, the first predicted time, and the second predicted time corresponds to a preset condition. If all of the corresponding preset conditions are met, it is determined that the moving speed of the virtual object is not abnormal; otherwise, if at least one of the predicted average speed, the first predicted time, and the second predicted time does not meet the preset condition, it is determined that the moving speed of the virtual object is abnormal. The above preset conditions will be described in detail below in conjunction with specific embodiments.

[0068] As an optional implementation, the above method further includes:

[0069] When it is determined that the moving speed of the virtual object is abnormal, the account in the first client is controlled to go offline or the operation of the account in the game scene is restricted.

[0070] For example, if it is determined that the movement speed of the virtual object is abnormal, it is considered that the main player has adopted cheating means, the state of the virtual object in the server will not be set, and a cheating feedback package will be sent to the main end to execute the penalty logic, such as kicking the player off the car, forcibly pulling the main player's coordinates, etc.

[0071] In the related art, the first movement information received by the server at time S1 only includes the first coordinate, and the second movement information received at time S2 only includes the second coordinate. Then, according to the time S1 when the server actually receives the first movement information and the time S2 when the server actually receives the second movement information, the time difference is calculated, and the target distance between the first coordinate and the second coordinate is calculated, and then the predicted average speed is calculated. In other words, in the related art, the predicted average speed is calculated based on the server time, and it is not considered that when the network condition in the first client is poor, the time difference between the first movement information and the second movement information received by the server may be compressed or extended, thereby misjudging the player 1 in the first client for speeding cheating or missing the real cheating situation, resulting in the problem of low accuracy of the detection result of the virtual object.

[0072] Compared with the technical solutions in the related art, the technical solution in the embodiment of the present application respectively adds timestamps to the first movement information and the second movement information, so that the server calculates a more accurate predicted average speed according to the two predicted times in the timestamps, thereby obtaining a more accurate detection result based on the predicted average speed, reducing the misjudgment rate and achieving the technical effect of improving the accuracy of the detection results of virtual objects.

[0073] As an optional implementation, the above method of determining that the moving speed of the virtual object is abnormal when at least one of the predicted average speed, the first predicted time, and the second predicted time does not meet a preset condition includes:

[0074] When the preset conditions include at least one of N conditions, and at least one of the predicted average speed, the first predicted time, and the second predicted time does not satisfy at least one of the N conditions, it is determined that there is an abnormality in the moving speed of the virtual object, where N is a positive integer greater than or equal to 2.

[0075] Each of the N conditions is independent of each other, and there is no restriction on the order of precedence in determining whether the moving speed of the virtual object is abnormal.

[0076] As an optional example, the above N conditions include:

[0077] The first prediction time is less than the first reception time, and the second prediction time is less than the second reception time, where the first reception time is the actual time when the server receives the first movement information, and the second reception time is the actual information when the server receives the second movement information;

[0078] The target prediction time difference is greater than or equal to the reciprocal of the target frame rate, where the first client is set to send the movement information of the virtual object to the server at the target frame rate;

[0079] The time difference between the first reception time and the first prediction time is greater than a multiple of the network delay duration, and the network delay duration is the total duration from when the first client sends the first movement information to the server until the first client receives the confirmation message of the first movement information sent by the server;

[0080] The predicted average speed is less than the average speed threshold, where the average speed threshold is the speed determined according to the attribute information of the virtual object, and the attribute information of the virtual object includes the performance parameters of the virtual object and the hardware parameters of the target terminal, and the target terminal is used to display the virtual object in the game scene.

[0081] Assuming that the first prediction time is S1' and the second prediction time is S2', at least one of the above predicted average speed, the first prediction time S1', and the second prediction time S2' needs to satisfy the N conditions including but not limited to at least one of the following:

[0082] (1) S1' < S1 and S2' < S2;

[0083] That is, the time S1 when the server actually receives the first movement information is later than the first prediction time S1' predicted by the first client, and the time S2 when the server actually receives the second movement information is later than the second prediction time S2' predicted by the first client.

[0084] This is because both the first prediction time and the second prediction time are obtained by adding the time offset of the first client to the time synchronization time, and theoretically, it should be two network delay times less than the time when the server actually receives the first movement information and the second movement information.

[0085] Using this condition, it is possible to intercept the situation where the time of the first client passes faster than the server due to mainstream accelerator cheats.

[0086] (2) S2' - S1' ≧ 1 / FPS, where FPS is the reporting frame rate at which the first client sends the movement information of the virtual object to the server;

[0087] For example, when the master reports 4 vehicle movement request packets per second, S2'-S1' needs to be greater than or equal to 250ms. This rule can prevent cheating to modify the protocol reporting data, send more than the agreed packets or shorten the packet time interval. In actual applications, since the master machine may freeze, etc., a little buffer needs to be left for the time determination, for example, greater than or equal to 240ms.

[0088] (3) S1-S1'>P*RTT;

[0089] Combined with the description in the above embodiment, it can be known that the first predicted time (or second predicted time) reported by the first client is earlier than the time when the server actually receives the first movement information (or second movement information), but it cannot be too much smaller. Through this condition, it can effectively prevent the master end from modifying the predicted time in the protocol to a very early time, accumulating a certain amount of packets and sending them instantly, causing the virtual object (for example, virtual vehicle) to move instantly. For systems where it is inconvenient to obtain RTT, a fixed threshold can be set, for example, 5S.

[0090] It should be noted that the movement information of the virtual object reported by the first client to the server at a preset time interval includes but is not limited to the coordinate information of the virtual object at different times and the corresponding predicted time when the server receives the movement information. For some parameters in the movement information, the player may modify the parameter values ​​in the protocol through the background, for example, modify the first predicted time to another time earlier than the actual predicted time. In order to prevent players from using such cheating methods, the above condition S1-S1'>P*RTT is set.

[0091] (4) The predicted average speed is less than the preset average speed threshold.

[0092] According to the first coordinate and the second coordinate reported twice by the first client, the coordinate displacement difference (which can also be understood as the target distance) L of the two movements reported is calculated; according to the first predicted time S1' and the second predicted time S2' reported twice by the first client, the predicted time difference T=S2'-S1' is calculated, and L / T is the predicted average speed.

[0093] Among them, the preset average speed threshold can be but is not limited to a value pre-set according to the attribute information of each virtual object. For example, according to the power parameters of virtual vehicle 1, its reasonable average speed threshold is determined to be 80km / h, and according to the power parameters of virtual vehicle 2, its reasonable average speed threshold is determined to be 60km / h, etc.

[0094] Average speed thresholds corresponding to different virtual objects are pre-stored in the server. When the server calculates the predicted average speed according to the movement information reported by the first client, the two are compared.

[0095] In a multi-player online game, when a player causes a virtual object to move from a first position to a second position through a triggering operation in the main client (e.g., the first client), the server sends the movement information to a third party so that the process of the virtual object moving from the first position to the second position is displayed on the game screen of the third party.

[0096] During the process of displaying on the game screen of the third party the virtual object moving from the first position to the second position, problems described in the following embodiments may occur.

[0097] Refer to Figure 6 As shown in (a) of [reference], assume that the virtual object is a car, and the car travels from left to right along the road at a constant speed V. The initial reported position is at time T0, and the next report is at time T1 (fixed time interval ΔT = T1 - T0). It can be seen that the positions of the car on the server are discrete, and the interval size depends on the reporting frequency and the driving speed of the car.

[0098] Assume that at time Tx (T0 < Tx < T1), a monster releases an explosion skill in the middle of the road, and the explosive will cause damage to players within a radius of 3 meters. Since the damage range selection and numerical calculation are both performed on the server, there will be a situation where the player on the main end (e.g., the first client) sees himself within the explosion range but does not receive any damage.

[0099] To avoid the above-mentioned inconsistency in the main-end experience, in the embodiments of the present application, a simulation method for the virtual object movement logic also needs to be performed on the server, specifically including:

[0100] When the first movement information and the second movement information are the movement information of the virtual object sent by the first client to the server in two adjacent times, according to the first movement information and the second movement information, a set of predicted movement information of the virtual object is determined, where a set of predicted movement information includes M predicted times and M predicted coordinates, and the M predicted coordinates represent the positions of the virtual object at the M predicted times during the process of the virtual object moving from the first position to the second position, and M is a positive integer greater than or equal to 1;

[0101] Send the first movement information, the second movement information, and a set of predicted movement information to the second client, where the second client is used to display the process of the virtual object in the game scene moving from the first position to the second position according to the first movement information, the second movement information, and a set of predicted movement information.

[0102] Such as Figure 6As shown in (a), assuming that the time when the first client reports the first movement information is T0, and the time when the second movement information is next reported is T1, a set of predicted movement information is determined based on the first movement information and the second movement information. For example, in the process of the virtual object moving from the first position to the second position, M predicted times and M predicted coordinates are simulated.

[0103] For details, please refer to Figure 6 As shown in (b), when the server receives the first movement information reported by the first client at time T0, it calculates the simulated position of the car on the server with a smaller preset time interval (for example, ΔT / 2, ΔT / 3, etc.) and pre-set speed, acceleration and other parameters, and updates the simulated position to between the first position and the second position.

[0104] Obviously, Figure 6 The simulated position shown in (b) is only an example and is not limited thereto. For example, a discrete position corresponding to the time ΔT / 3 or multiple discrete positions corresponding to other multiple times may also be simulated.

[0105] When the predicted average speed, the first predicted time and the second predicted time meet the above N conditions, the first movement information, the second movement information and a set of predicted movement information are sent to the second client through the server to display the above movement process of the virtual object in the second client, wherein the third party includes the second client.

[0106] The discrete positions obtained by the above logic simulation can be used to fill the discrete positions of the virtual vehicle in the server, so that the discrete intervals are reduced to alleviate the inconsistent experience of the main end (the first client).

[0107] As an optional implementation manner, determining a set of predicted movement information of the virtual object according to the first movement information and the second movement information includes:

[0108] When the first movement information also includes the first movement parameter, M prediction times and M prediction coordinates are determined according to the target prediction time difference and the first movement parameter, wherein the first movement parameter includes the first movement speed of the virtual object at the first position, or the first movement speed and the first movement acceleration of the virtual object at the first position.

[0109] Among them, the first movement parameter includes but is not limited to the first coordinate of the first position of the virtual object and the first predicted time when the server receives the first movement information, and M predicted times and M predicted coordinates are determined according to the target predicted time difference, the first predicted time and the first coordinate.

[0110] As an alternative example, determining M prediction times and M prediction coordinates according to the target prediction time difference and the first movement parameter as described above includes:

[0111] Dividing the target prediction time difference evenly into M + 1 time intervals, and determining the M prediction times as the times separated from the first prediction time by 1 to M time intervals;

[0112] When the first movement parameter includes the first movement speed, determining the M prediction coordinates according to the first coordinate, the first movement speed, and the M prediction times, where the distance between the i-th coordinate among the M prediction coordinates and the first coordinate is equal to the product of the first movement speed and i time intervals, and i is a positive integer greater than or equal to 1 and less than or equal to M;

[0113] When the first movement parameter includes the first movement speed and the first movement acceleration, determining the M prediction coordinates according to the first coordinate, the first movement speed, the first movement acceleration, and the M prediction times, where the distance between the i-th coordinate among the M prediction coordinates is the distance determined according to the first movement speed, the first movement acceleration, and i time intervals.

[0114] For example, assume the target prediction time difference ΔT = 3s and M = 2, that is, dividing ΔT evenly into 3 time intervals, and the divided time interval is ΔT' = 1s. The times S1' + ΔT', S1' + 2ΔT', and S1' + 3ΔT' separated from the first prediction time S1' by ΔT', 2ΔT', and 3ΔT' respectively are determined as the M prediction times.

[0115] It should be noted that in addition to calculating the server vehicle position at a fixed time interval ΔT in the above embodiments to supplement the discrete coordinate points of the virtual object, a linear calculation method can also be used to simulate and obtain the real-time position of the virtual object.

[0116] As shown in (a) of Figure 6 At any Ty moment (T0 < Ty < T1), the trolley coordinate Ly = L0 + V * (Ty - T0), that is, by taking the current movement state as a reference, calculating the position of the trolley in a short time to complete the discrete position coordinates of the server.

[0117] Through the above method, the diversity of the method for supplementing the discrete positions of virtual objects on the server side is increased, and the applicable range of the technical solution of the present application is improved.

[0118] As an alternative example, before obtaining the first movement information and the second movement information of the virtual object sent by the first client to the server, the above method further includes:

[0119] In response to the time synchronization request sent by the first client, sending a time synchronization data packet to the first client, wherein the time synchronization data packet includes the server time on the server;

[0120] The first predicted time is the predicted time determined according to S0, C1 and C0, S0 represents the server time, C1 represents the sending time of the first mobile information sent by the first client to the server, and C0 represents the receiving time of the time synchronization data packet received by the first client;

[0121] The second predicted time is a predicted time determined according to S0, C2 and C0, and C2 represents the sending time of the second movement information sent by the first client to the server.

[0122] Combine the following Figure 7 The overall flow chart shown further describes the above virtual object detection method, and the specific steps are as follows:

[0123] S702, the master sends a time synchronization request to the server at a fixed time interval;

[0124] For example, the first client (master end) sends a time synchronization request to the server once every 5 seconds.

[0125] S704, the server sends a time synchronization response packet to the first client;

[0126] For example, Figure 5 As shown, after the server receives the time synchronization request sent by the first client, the server sends the current server time S0 to the first client.

[0127] S706, the first client sends an operation request packet of the virtual object to the server;

[0128] For example, the throttle size of the virtual vehicle, the steering angle of the steering wheel, whether to honk the horn, etc., and set the corresponding server parameters after receiving the operation request.

[0129] S708, broadcasting the server parameters corresponding to the settings to a third party;

[0130] For example, the server parameters include parameters related to the throttle size, steering wheel steering angle, whether to honk, etc. of the virtual vehicle in the operation request packet sent from the first client.

[0131] S710, the first client sends a movement request packet to the server at a fixed time interval;

[0132] For example, a mobile request packet is sent to the server four times per second, and the server verifies the legitimacy of the mobile request parameters in the mobile request packet, as specifically described in step S712.

[0133] S712, verifying the mobility request parameters and legitimacy in the mobility request packet;

[0134] For details, please refer to the description in the above embodiment on determining that there is no abnormal part in the moving speed of the virtual object when the predicted average speed, the first predicted time and the second predicted time need to meet N preset conditions, which will not be repeated here.

[0135] S714, when the legitimacy of the mobile request parameters in the mobile request packet is not verified, feeding back the abnormality detection result to the first client;

[0136] If it fails, it is considered that the first client has adopted cheating means, the state of the virtual object in the server is not set, and a cheating feedback package is sent to the first client to execute the penalty logic, such as kicking the player off the car, forcibly pulling the coordinates of the main player, etc.

[0137] S716, if the verification is passed, setting the movement state of the corresponding virtual object on the server and broadcasting it to the third party;

[0138] S718, the server performs logic simulation at fixed time intervals according to the movement state of the virtual object, and updates the position of the virtual object on the server side.

[0139] For example, the simulated position of the car on the server is calculated with a smaller preset time interval (for example, ΔT / 2, ΔT / 3, etc.) and preset speed, acceleration and other parameters. For details, please refer to the above embodiment for Figure 6 The description of (b) will not be repeated here.

[0140] contrast Figure 8 The statistical results of the super average speed in the prior art solution shown in (a) and Figure 8 From the statistical results of the super-average speed in the technical solution of the present application shown in (b), it can be intuitively seen that after adopting the technical solution of the present application, the number of people recorded as cheating every day has been greatly reduced. According to the network delay reported by the main end and the sampling survey test, it was found that the technical solution of the present application eliminated a large number of misjudgments caused by network delays and sticky packets, and improved the accuracy of the average speed verification.

[0141] In addition, in the technical solution of the present application, by introducing a time-based vehicle movement synchronization method, a specific verification method is provided, which improves the accuracy of the average speed verification and reduces the possibility of cheating by modifying the protocol on the master side; by introducing the logical simulation of the server virtual objects, the discrete position intervals of the server virtual objects are reduced, thereby improving the experience of the master-side players.

[0142] As an optional example, the first prediction time is a prediction time determined according to S0, C1 and C0, and the second prediction time is a prediction time determined according to S0, C2 and C0, including:

[0143] Calculate the difference between C1 and C0 to obtain a first difference;

[0144] Calculate the difference between C2 and C0 to obtain a second difference;

[0145] Sum S0 and the first difference to obtain a first predicted time;

[0146] S0 and the second difference are summed to obtain the second predicted time.

[0147] For example, the first predicted time S1′=S0+C1-C0, and the second predicted time S2′=S0+C2-C0, wherein C1-C0 and C2-C0 are both time deviations of the first client.

[0148] As another optional example, the first predicted time is a predicted time determined according to S0, C1 and C0, and the second predicted time is a predicted time determined according to S0, C2 and C0, further comprising:

[0149] Calculate the difference between C1 and C0 to obtain a first difference;

[0150] Calculate the difference between C2 and C0 to obtain a second difference;

[0151] Sum S0, the first difference and RTT to obtain a first predicted time;

[0152] Sum S0, the second difference and RTT to obtain a second predicted time;

[0153] RTT represents the network delay duration, which is the total duration between the first client sending the first mobile information to the server and the first client receiving the confirmation message of the first mobile information sent by the server.

[0154] For example, the first predicted time S1'=S0+C1-C0+RTT, and the second predicted time S2'=S0+C2-C0+RTT, wherein RTT is the total duration of the first network delay duration for the first client to send the first mobile information to the server and the second network delay duration for the first client to receive the confirmation message of the first mobile information sent by the server.

[0155] In order to solve the problem of low accuracy in the above-mentioned virtual object detection process, another virtual object detection method is also proposed in the embodiment of the present application, which is applied to the detection of virtual objects on the first client side. The specific process is as follows: Figure 3 The following steps are shown:

[0156] Step S302, sending a time synchronization request to the server;

[0157] Step S304, obtaining a time synchronization data packet sent by the server in response to the time synchronization request, wherein the time synchronization data packet includes the server time on the server;

[0158] Step S306, determining the first predicted time according to S0, C1 and C0, and sending the first movement information of the virtual object to the server, wherein S0 represents the server time, C1 represents the sending time of the first movement information sent by the first client to the server, C0 represents the receiving time of the time synchronization data packet received by the first client, the first movement information includes the first predicted time and the first coordinate, the first predicted time represents the predicted time when the server receives the first movement information, and the first coordinate represents the first position of the virtual object in the game scene;

[0159] Step S308, determining the second predicted time according to S0, C2 and C0, and sending second movement information of the virtual object to the server, wherein C2 represents the sending time of the second movement information sent by the first client to the server, the second movement information includes the second predicted time and the second coordinate, the second predicted time represents the predicted time when the server receives the second movement information, and the second coordinate represents the second position when the virtual object moves from the first position to the second position in the game scene;

[0160] The first moving time and the second moving time are used to determine whether there is an abnormality in the moving speed of the virtual object.

[0161] like Figure 5 As shown, the first client sends a time synchronization request to the server at a fixed time interval, and receives a time synchronization data packet sent by the server at time C0, wherein the time synchronization data packet includes the server time S0 on the server.

[0162] Assuming that the first client sends the first movement information to the server at time C1, the first prediction time S1'=S0+C1-C0 is calculated. Similarly, assuming that the first client sends the second movement information to the server at time C2, the second prediction time S2'=S0+C2-C0 is calculated.

[0163] Alternatively, the first prediction time and the second prediction time are calculated by using the method of first prediction time S1'=S0+C1-C0+RTT, second prediction time S2'=S0+C2-C0+RTT, wherein RTT is the total duration of the first network delay for the first client to send the first mobile information to the server and the second network delay for the first client to receive a confirmation message for the first mobile information sent by the server.

[0164] Through the above method, time synchronization between the server and the first client can be achieved, and a synchronization timestamp can be added to the subsequent movement information, thereby accurately limiting the frequency of mobile information reporting and the reported movement distance, reducing the probability of misjudgment in background detection, and limiting the conditions for players to cheat using plug-in tools.

[0165] In order to solve the problem of low accuracy in the above-mentioned virtual object detection process, a method for displaying a virtual object is also proposed in the embodiment of the present application, which is applied to the second client (third party). The specific process is as follows: Figure 4 The following steps are shown:

[0166] Step S402, receiving first movement information, second movement information and a set of predicted movement information sent by the server, wherein the first movement information includes a first predicted time and a first coordinate, the first predicted time indicates the predicted time when the server receives the first movement information, and the first coordinate indicates the first position of the virtual object in the game scene, the second movement information includes a second predicted time and a second coordinate, the second predicted time indicates the predicted time when the server receives the second movement information, and the second coordinate indicates the second position when the virtual object moves from the first position to the second position in the game scene, the set of predicted movement information is the predicted movement information determined based on the first movement information and the second movement information, the set of predicted movement information includes M predicted times and M predicted coordinates, the M predicted coordinates indicate the position of the virtual object at the M predicted times in the process of the virtual object moving from the first position to the second position, and M is a positive integer greater than or equal to 1;

[0167] Step S404, displaying a process of a virtual object in a game scene moving from a first position to a second position according to the first movement information, the second movement information and a set of predicted movement information.

[0168] When the server verifies the first movement information and the second movement information reported by the first client, the server sends the first movement information, the second movement information and a set of predicted movement information to the second client, and displays the process of the virtual object in the game scene moving from the first position to the second position in the second client according to the first movement information, the second movement information and the set of predicted movement information.

[0169] For example, based on the server logic simulation, Figure 6 The predicted coordinates and predicted time of the simulated position shown in (a) above display the process of the virtual object moving from the first position to the second position in the second client.
