Background

In a virtual shooting game application, it is often necessary to determine the position of each second virtual object that is a competitor with a first virtual object currently controlled by a player, so as to facilitate timely and accurate targeting of the second virtual object of an opponent to complete a shooting action.

However, in the virtual scene provided by the current virtual shooting game application, the position of the second virtual object of the competitor can only be observed according to the visual field of the current player. For example, in the case where the current player is viewing using the first-person shooting perspective, if it is detected that a second virtual object of one of the competitors appears in the upper left corner of the current display interface, it is determined that the second virtual object appears in front of the current player's current field of view. A control command input through an input device associated with the client may be obtained to implement a shooting action on the second virtual object.

That is, when the second virtual object appearing during shooting is located by visual observation, it is possible that the first virtual object has been hit by the second virtual object when the second virtual object is found by the human eye due to a problem of delayed observation reaction that exists in the human eye itself. In other words, the object positioning method provided by the related art has a problem of low positioning efficiency.

In view of the above problems, no effective solution has been proposed.

According to an aspect of the embodiments of the present invention, there is provided an object positioning method, optionally, as an optional implementation manner, the object positioning method may be applied, but not limited, to an object positioning system in an environment as shown in fig. 1, where the object positioning system may include, but is not limited to, a terminal device 102, a network 104, and a server 106. A shooting application client is running in the terminal device 102. The terminal device 102 includes a human-machine interaction screen 1022, a processor 1024, and a memory 1026.

The memory 1026 is configured to store object attribute information of the first virtual object and the second virtual object, where the object attribute information includes a position of the first virtual object and a position of the second virtual object.

In addition, the server 106 includes a database 1062 and a processing engine 1064, and the database 1062 is used to store attribute information and state information of each virtual object. The processing engine 1064 is configured to obtain a location of the first virtual object and a location of the second virtual object.

The specific process comprises the following steps: assume that a virtual scene screen provided by a shooting application client is displayed in a terminal device (e.g., a mobile terminal) 102, wherein a first virtual object 12 and a second virtual object 14 are in a fighting relationship of different campuses, and a virtual scanning panel (shown as a semi-circle shape) is displayed in a positioning induction prop 16.

In steps S102 to S104, when a first virtual object controlled by a shooting application client running in the terminal device 102 is configured with a positioning sensing prop, the resource amount of a virtual resource accumulated after the first virtual object executes a shooting action in a target time period is obtained, and the resource amount of the virtual resource is sent to the server 106 through the network 104. The positioning induction prop is used for regularly scanning a second virtual object in a target scanning area associated with the first virtual object. Where the second virtual object is a different lineup than the first virtual object. Then, the service provider 106 calls the trigger condition stored in the database 1062, and determines, by the processing engine 1064, whether the resource amount of the received virtual resource reaches the trigger condition, and if the resource amount of the received virtual resource reaches the trigger condition, executes step S106, and obtains the position of at least one second virtual object by using the positioning sensing prop configured by the first virtual object. Then, in step S108, the location of the at least one second virtual object is sent to the terminal device 102 through the network 104, so that the terminal device 102 executes step S110 to display the location of the second virtual object in a virtual scanning panel provided by the positioning sensing prop.

In addition, the steps and the interaction sequence shown in fig. 1 are examples, and the operations executed by the server 106 in this embodiment may also be executed by the terminal device 102 instead, that is, the terminal device 102 may independently complete the object positioning method when the processing capability of the terminal device meets a certain condition. This is not limited in this embodiment.

It should be noted that, in this embodiment, when the first virtual object controlled by the shooting application client is configured with the positioning sensing prop, the resource amount of the virtual resource accumulated after the first virtual object executes the shooting action in the target time period is obtained. And under the condition that the resource amount of the virtual resource reaches a trigger condition, the positioning sensing prop is used for periodically scanning a second virtual object in a target scanning area associated with the first virtual object so as to obtain the position of at least one second virtual object. And then, displaying the position of the second virtual object in a virtual scanning panel provided by the positioning sensing prop in the shooting application client. Therefore, the second virtual object appearing near the first virtual object is periodically scanned by utilizing the positioning induction prop, and the second virtual object is timely displayed in the virtual scanning panel provided by the positioning induction prop, so that the positioning efficiency of the virtual object is improved, the first virtual object can conveniently and timely make an action strategy, the counterattack or the avoidance is completed in the first time, the success rate of the first virtual object in a shooting game task is improved, and the problem of lower positioning efficiency of the virtual object in the related technology is solved.

The server may be a single server, a server cluster composed of a plurality of servers, or a cloud server. The above is merely an example, and this is not limited in this embodiment.

Optionally, as an optional implementation manner, as shown in fig. 2, the object positioning method includes:

s202, under the condition that a first virtual object controlled by a shooting application client is configured with a positioning induction prop, acquiring the resource amount of virtual resources accumulated after the first virtual object executes a shooting action in a target time period, wherein the positioning induction prop is used for regularly scanning a second virtual object in a target scanning area associated with the first virtual object, and the second virtual object and the first virtual object are in different camps;

s206, displaying the position of the second virtual object in a virtual scanning panel provided by the positioning sensing prop.

Optionally, in this embodiment, the object positioning method may be applied, but not limited to, in a game application, for example, the position of each virtual object participating in one game task is visually positioned, so that a player can intuitively and accurately distinguish the position of the virtual object in a game scene. The Game application may be a Multiplayer Online Battle sports Game (MOBA) application, or a Single-Player Game (SPG) application. The types of gaming applications described above may include, but are not limited to, at least one of: two-dimensional (2D) game applications, Three-dimensional (3D) game applications, Virtual Reality (VR) game applications, Augmented Reality (AR) game applications, Mixed Reality (MR) game applications. The above is merely an example, and the present embodiment is not limited to this.

Further, the Shooting Game application may be a Third Person Shooting Game (TPS) application, which is executed from the perspective of a Third-party virtual object other than a virtual object controlled by a current player, or a First Person Shooting Game (FPS) application, which is executed from the perspective of a First virtual object controlled by a current player. Correspondingly, the second virtual object that is described above in connection with the first virtual object may be, but is not limited to: virtual objects (also referred to as Player characters), Non-Player characters (NPCs for short) controlled by players through respective game application clients, and the like. The above is merely an example, and this is not limited in this embodiment.

Optionally, in this embodiment, the positioning sensing prop may be, but is not limited to, used for periodically scanning the second virtual object in the target scanning area associated with the first virtual object. The positioning induction prop can be but not limited to a heartbeat inductor simulated in a virtual scene, and the position of the second virtual object is positioned and found by inducing an electric field generated by an ultralow frequency electric wave generated by a simulated human body and emitted by the virtual object. It should be noted that the ultralow frequency electric wave can penetrate through the reinforced concrete wall and the steel plate to detect the ultralow frequency electric field emitted by the virtual object simulating human body, and the artificial object is a tactical prop for assisting the first virtual object to win.

For example, as shown in fig. 3, a shooting interface of a first-person shooting perspective of a first virtual object controlled by a shooting application client is shown, and a second virtual object in a different formation from the first virtual object is an object 300. Here, the first virtual object is configured with a location-sensing prop 302, which provides a virtual scanning panel as shown in the figure as panel 306, wherein the location of the location-sensed object 300 will be displayed in the panel 306, such as the location of the solid point 304.

Optionally, in this embodiment, the virtual resources accumulated after the shooting action is performed may include, but are not limited to: virtual gold coins for realizing virtual transaction in a virtual scene, and virtual credits for exchange. That is, after each completion of the shooting action, the virtual object acquires a virtual resource of a resource amount corresponding to the degree of completion of the shooting action. For example, the amount of resources of the virtual resources accumulated after the shooting action is performed in the target time period may be, but is not limited to, a reward point obtained after the first virtual object performs consecutive killing. Correspondingly, the triggering condition may be, but is not limited to, whether the resource amount of the virtual resource is greater than a certain threshold, for example, when the resource amount of the virtual resource is a reward point obtained after the linking, and when the reward point is greater than the threshold, the position of the second virtual object in the sensing target scanning area may be located by using the location sensing device.

It should be noted that the target scanning area may be, but is not limited to, an area range allowing scanning detection configured for the first virtual object in advance: and determining a hemisphere space area according to a certain scanning radius by taking the position of the first virtual object as a circle center. Here, the hemispherical space region is determined from the front of the line of sight of the first virtual object without distinguishing whether the first virtual object is raised or lowered. For example, as shown in fig. 4, it is assumed that the scanning radius is 30 meters (m), and [ -30, 30] in the horizontal direction and [0, 30] in the vertical direction constitute a target scanning area associated with the first virtual object. Further, here, the first virtual objects of different character attributes or different levels may be, but are not limited to, configured with different ranges of target scanning areas. For example, the scan radius of the target scan area of the first virtual object of level 1 is 5m, and the scan radius of the target scan area of the second virtual object is 30 m. For another example, the scanning radius of the target scanning area of the first virtual object with the short range shooter attribute is 3m, and the scanning radius of the target scanning area of the first virtual object with the long range shooter attribute is 6 m.

Optionally, in this embodiment, at least one second virtual object may be displayed in the virtual scanning panel provided by the positioning sensing prop. That is, all the second virtual objects in an enemy camp different from the first virtual object may be displayed, or a part of the second virtual objects may be displayed, for example, one second virtual object may be displayed. One second virtual object here may be, but is not limited to, the second virtual object closest to the first virtual object.

In addition, in this embodiment, while the position of the second virtual object is displayed in the virtual scan panel, the distance of the second virtual object from the first virtual object may also be prompted. When the distances are different, the prompting mode of the prompting information is correspondingly adjusted, so that the first virtual object can visually and vividly distinguish the position change of the second virtual object relative to the first virtual object.

The description is made with specific reference to the following examples: it is assumed that the first virtual object and the second virtual object are parties of different camps in a one-shot game task. Under the condition that a click operation is executed on a configuration key of an application client side for equipping a sensing positioning prop (hereinafter referred to as a heartbeat sensing device) for a first virtual object, the sensing positioning prop is configured on the first virtual object, then the fact that a continuous killing reward integral of the first virtual object in a target time period reaches a threshold value is detected, and if the continuous killing reward integral reaches the threshold value, a second virtual object in a target scanning area matched with the first virtual object is scanned and detected by using the heartbeat sensing device in the action time period.

Specifically, the flowchart shown in fig. 5 may be positioned, and in step S502, the static parameters of the virtual scan panel and the scan circle parameters during scanning are initialized. For example, assuming that the static floor radius of the virtual scan panel may be radius r (as shown in panel 306 of FIG. 3), the scan circle parameter may be that the scan circle is periodic by T and is periodically scanned by 30 m. Then, in step S504, during the scanning process, real-time parameters of the scanning circle are dynamically calculated in real time, and if the sensing circle is in front of the line of sight of the first virtual object, the sensing scanning is started from 0 until the scanning radius reaches 30 m.

That is, the parameters of the scanning circle of the heartbeat sensing device are calculated at each cycle to obtain the radius of the current scanning circle and then transmitted to the Shader. In addition, when the heartbeat sensing device is in an effective action time period, the second virtual object of the enemy can be traversed by taking the position of the first virtual object as the center of a circle at intervals of T seconds, and whether the second virtual object of the enemy appears in a target scanning area of 30m or not is detected. If at least one second virtual object is detected, the position of each of the at least one second virtual object and the first virtual object in the virtual scene needs to be converted into a display position on the map of the virtual scanning panel. Wherein, the horizontal direction scanning range [ -30, 30] in the target scanning area is mapped to the horizontal direction mapping coordinate range [0, 1], and the vertical direction scanning range [0, 30] is mapped to the vertical direction mapping coordinate range [0, 1 ]. Here, after the position of the second virtual object is obtained, the coordinate transformation can be implemented by the following function, and the second virtual object is mapped into the virtual scan panel for display:

drawCall.dynamicMaterial.SetVector(paraID,paraValue)；

wherein, the paraID can respectively enter the scanning radius and the identifier of the second virtual object, and the paraValue respectively represents the scanning radius and the position of the second virtual object.

As in steps S506 to S514: determining whether a second virtual object is detected, and determining the position of the second virtual object when the second virtual object is detected. And setting a Shader parameter according to the position. Then detect if the usage cut-off time of the location sensitive prop (i.e. heartbeat sensing device)? If the use ending time is determined to be reached, the positioning sensing prop (namely the heartbeat sensing device) is retracted.

The steps and the sequence shown in fig. 5 are examples, and this embodiment is not limited in this respect.

By the embodiment provided by the application, under the condition that the first virtual object controlled by the shooting application client is configured with the positioning induction prop, the resource amount of the virtual resource accumulated after the first virtual object executes the shooting action in the target time period is obtained. And under the condition that the resource amount of the virtual resource reaches a trigger condition, the positioning sensing prop is used for periodically scanning a second virtual object in a target scanning area associated with the first virtual object so as to obtain the position of at least one second virtual object. And then, displaying the position of the second virtual object in a virtual scanning panel provided by the positioning sensing prop in the shooting application client. Therefore, the second virtual object appearing near the first virtual object is periodically scanned by utilizing the positioning induction prop, and the second virtual object is timely displayed in the virtual scanning panel provided by the positioning induction prop, so that the positioning efficiency of the virtual object is improved, the first virtual object can conveniently and timely make an action strategy, the counterattack or the avoidance is completed in the first time, the success rate of the first virtual object in a shooting game task is improved, and the problem of lower positioning efficiency of the virtual object in the related technology is solved.

As an optional scheme, the obtaining, by using the positioning sensing prop, a position of the at least one second virtual object includes: scanning a second virtual object appearing in the target scanning area according to a target period to acquire the position of at least one second virtual object; displaying the position of the second virtual object in a virtual scanning panel provided by the positioning sensing prop comprises: and updating the position of the second virtual object displayed in the virtual scanning panel according to the target period.

Optionally, in this embodiment, the positioning sensing prop is a tactical prop that periodically scans and searches for the second virtual object. The rendering effect can be, but is not limited to, displayed by assigning a dynamically changeable shader parameter to the panel (mesh). The positioning sensing device herein may include, but is not limited to, the following: a bottom static panel, a dynamic scan circle, a position icon of a position where the second virtual object is located. For example, as shown in fig. 6, the bottom static panel 602 is a bottom plate of the virtual scan panel, and the static parameters of the bottom static panel 602 are used to indicate information such as a display area and a display area of the virtual scan panel in the virtual scene. The dynamic scan circle 604 is used to indicate the position of the current scan circle (gray circle) during the scan. It should be noted that, here, the scanning process of the virtual scanning panel is a periodic dynamic scanning, and the dynamic scanning circle 604 will implement a sensing process from 0 to the end of the scanning radius R in each scanning period. The location icon 606 of where the second virtual object is located may be represented by a solid circle. Here, the display mode of the position icon is not limited to this, and various figures such as a hollow circle, a triangle, and the like, and combinations thereof may be used. Further, when the position icon at which the second virtual object is located is a triangle, the orientation of the triangle may also indicate the current orientation of the second virtual object. Here, this is an example, and this is not limited in this embodiment.

For example, assuming that a first virtual object is currently using a positioning sensing prop, its virtual scanning panel scans every 3 seconds, and each time scanning, the position of a second virtual object in the scanned area and the distance between the second virtual object and the first virtual object are displayed on the screen. In this example, the distance may be accurate to 0.1 m.

Through the embodiment provided by the application, the positioning induction prop is used for scanning and detecting the second virtual object of the enemy positioned in the target scanning area associated with the first virtual object according to the target period in the virtual scene provided by the shooting application client, so that the second virtual object close to the first virtual object can be found in time, the first virtual object can be visually prompted to take a fighting action on the second virtual object, and the first virtual object can be prevented from being killed.

As an alternative, updating the position of the second virtual object displayed in the virtual scan panel according to the target period includes:

s1, acquiring the position of the first virtual object and the position of the second virtual object in the current target period;

s2, updating the position of the second virtual object displayed on the virtual scan panel in the next target period after the target period when the position of the first virtual object is changed;

s3, when the position of the second virtual object is changed, the position of the second virtual object displayed on the virtual scan panel is updated in a next target period after the target period.

In this embodiment, when it is detected that the position of the first virtual object is changed or the position of the second virtual object is changed in the current target period, the changed position is updated and displayed in the next target period after the current target period. That is, the position of the second virtual object does not change in real time, but the display is updated periodically according to the scanning period. That is, in the case where it is determined that the second virtual object has changed its position, the position is not updated in the current cycle, but is updated in the next cycle (i.e., the next scan). And under the condition that the position of the first virtual object is determined to be changed, the static parameters of the bottom static panel of the virtual scanning panel need to be updated, the virtual scanning panel displayed in the shooting application client side is reinitialized, and the position of the corresponding second virtual object is updated at the same time.

The description is made with reference to the example shown in fig. 7: assume that the position of the second virtual object 606 within the current target period T appears to be located at the outer edge of the target scanning area as shown in fig. 7 (a). Here the second virtual object 606 is moving, but its position in the virtual scan panel is maintained until the next target period T + 1. In the next target period T +1, it is detected that the position of the second virtual object 606 has changed, and has moved to the middle of the target scanning area as shown in fig. 7 (b).

Through the embodiment provided by the application, the position of the second virtual object displayed in the virtual scanning panel is updated according to the target period, so that the problem that the display screen is blocked and accurate positioning cannot be realized due to the fact that the moving speed of the second virtual object is too high is solved.

s1, acquiring the orientation of the first virtual object in real time in the current target period;

s2, when the orientation of the first virtual object changes, the position of the second virtual object displayed on the virtual scan panel is kept unchanged.

The description is made with reference to the example shown in fig. 8: it is assumed that the position of the second virtual object 606 in the current target period T is displayed at the outer edge on the right side of the target scanning area as shown in fig. 8 (a). In addition, if the orientation of the first virtual object changes within the target period T, such as turning to the right, although the relative relationship between the position of the second virtual object and the position of the first virtual object does not change, the orientation of the positioning sensing device changes, and the corresponding sensing model also changes, so that the position of the second virtual object 606 changes in the virtual scan panel, and the position is displayed at a display position close to the central axis as shown in fig. 8 (b).

By the embodiment provided by the application, when the orientation of the first virtual object changes, the position of the second virtual object scanned and displayed in the virtual scanning panel changes, so that the position of the second virtual object in the line-of-sight direction relative to the first virtual object is really located.

and S1, adjusting the brightness of the position icon at the position where the second virtual object is located in the target period, wherein the brightness is positively correlated with the display duration of the position icon.

Optionally, in order to avoid that the scanned position of the current target period causes display interference with the scanned position of the next target period, in this embodiment, the longer the display duration of the position icon is, the darker the corresponding brightness of the position icon is, and until the end of the target period, the position icon will disappear from the virtual scanning panel.

The description is made with reference to the example shown in fig. 9: assume that at the initial time T0 of the current target period T, the position of the second virtual object 606 is displayed at the right outer edge of the target scanning area as shown in fig. 9(a), and the brightness value of its position icon is P1, which may be represented by a black solid dot in the figure. As the display duration of the target period T progresses, assuming that the position of the second virtual object does not change, the brightness of the corresponding position icon is darkened. Assuming that the brightness value of the position icon is P2 at time t1 of the target period, the graph may be filled with dots as shown in FIG. 9 (b). Wherein, the luminance P1> luminance P2.

Through the embodiment provided by the application, the display duration change of the target period is prompted through different brightness of the position icon, and meanwhile, the display interference on the position scanned in the next target period is avoided.
