Description

Method and device for locking object in game

Technical Field

The present invention relates to the field of computers, and in particular, to a method and apparatus for locking an object in a game, an electronic device, and a storage medium.

Background

The target object locking function is a commonly used function in games, and can be used for providing a visualized target object for a player, wherein the player can perform a fight operation on the target object, such as attack on the target object, and can also perform an interactive operation on the target object, such as when the target object is a wooden case, the player can lift the wooden case and throw the wooden case, and in addition, the target object can also be applied to other functions, such as a destination serving as an automatic road finding function, and the like. As shown in fig. 1, which is a scenario in a game scene and in which a target object is unlocked, 101 is a virtual character controlled by a player, 102 is a non-player character, when the player locks the non-player character 102, as shown in fig. 2, a mark 201 for indicating that the target object has been locked appears on the top of the head of the non-player character 102, at this time, the player can select a direction through an external device, such as a keyboard, a joystick, etc., the locked target object can be changed from 102 to other interactable target objects in the selected direction, as shown in fig. 3, when the player presses a left direction key of the keyboard, the locked target object is changed to another non-player character 301 on the left side of the player 102, and a mark 302 appears on the top of the head.

The existing target object locking function needs to project targets in a game scene onto screen coordinates, then select the targets to be locked on a two-dimensional plane, and the targets are also selected on the two-dimensional plane. However, this screen-based approach is not applicable to AI (Artificial Intelligence ) controlled roles. Because the character controlled by the AI has no concept of a character camera, that is, the targets in the scene cannot be projected onto the screen presented by the character camera following the character, if the target locking of the AI character is to be realized, a target object locking method different from the character operated by the player needs to be adopted, so that more system resources are required to be consumed, the consistency of the two target object locking methods is difficult to be ensured, and the two target object locking methods are easy to collide to cause game errors.

It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The method of in-game object locking in one embodiment of the invention may be run on a terminal device or a server. The terminal device may be a local terminal device. When the method for locking the object in the game runs on the server, the method for locking the object in the game can be realized and executed based on a cloud interaction system, wherein the cloud interaction system comprises the server and the client device.

In an alternative embodiment, various cloud applications may be run under the cloud interaction system, for example: and (5) cloud game. Taking cloud game as an example, cloud game refers to a game mode based on cloud computing.

For example, the local terminal device may include a display screen for presenting a graphical user interface including game visuals, and a processor for running the game, generating the graphical user interface, and controlling the display of the graphical user interface on the display screen.

Referring to fig. 4, a flowchart illustrating steps of a method for locking an object in a game according to an embodiment of the present invention is provided, by a terminal device, a graphical user interface, where a content displayed by the graphical user interface includes a part or all of a virtual scene, and a virtual character located in the virtual scene, and the method specifically may include the following steps:

step 401, obtaining one or more interactable objects in the virtual scene according to the virtual character;

the virtual scenes can be game scenes in the game, and the objects in the game scenes can be divided into two types according to the function playing methods to be executed at present: interactive objects, which may include non-player enemies when performing an attack operation, and non-interactive objects, which may include non-player friendly characters, for example, for role-playing class games; while in the case of a give item operation, the interactable object may comprise a non-player friendly character and the non-interactable object may comprise a non-player enemy. According to the function playing method to be executed at present, one or more objects which can execute the function playing method to be executed at present in the virtual scene can be determined as interactable objects, and interactable objects meeting the requirements of users can be screened out from a plurality of objects in the virtual scene in a screening mode.

Step 402, obtaining position information of the one or more interactable objects in the virtual scene;

after determining the interactable objects, the positions of one or more interactable objects in the virtual scene may be obtained, respectively.

Step 403, determining spherical coordinates corresponding to the one or more interactable objects respectively according to the position information, wherein the spherical coordinates are coordinates in a spherical coordinate system determined according to the virtual character;

the spherical coordinate system is one of three-dimensional coordinate systems for determining the positions of points, lines, planes and bodies in three-dimensional space, and is composed of azimuth angle, elevation angle and distance by taking the origin of coordinates as a reference point. After the position information of the interactable objects in the virtual scene is obtained, the virtual character is taken as the origin of coordinates, and the spherical coordinates of each interactable object are obtained through coordinate conversion according to the position information.

Step 404, determining target spherical coordinates according to the spherical coordinates of the virtual character and the interactable object;

the virtual character includes a target character controlled by AI, and after the spherical coordinates of each interactable object are obtained, when the target character has no locked object, the most suitable spherical coordinates can be determined by the distance and angle difference between the spherical coordinates of the target character, i.e., the origin of coordinates, and the spherical coordinates of the interactable object. For example, the spherical coordinates having the smallest angle difference or the spherical coordinates of the target having the smallest distance when the angle difference is the same may be used.

And step 405, taking the interactable object corresponding to the target spherical coordinate as a locking object of the virtual character and locking.

And taking the interactable object corresponding to the target spherical coordinate as a locked object, and locking the interactable object.

In the embodiment of the invention, the position information of one or more interactable objects in the virtual scene is acquired by acquiring one or more interactable objects in the virtual scene according to the virtual role, the spherical coordinates corresponding to the one or more interactable objects respectively are determined according to the position information, the target spherical coordinates are determined according to the spherical coordinates of the virtual role and the interactable objects, the interactable object corresponding to the target spherical coordinates is used as a locking object of the virtual role and is locked, the optimal target object can be locked for the virtual role without using a role camera in the whole process, and the method is suitable for the virtual role controlled by a player and an AI (automatic identification) and not only reduces the consumption of system resources, but also avoids game errors possibly caused by adopting two target object locking methods.

Referring to fig. 5, a flowchart illustrating steps of another method for locking an object in a game according to an embodiment of the present invention is provided, where a graphical user interface is provided by a terminal device, and contents displayed by the graphical user interface include a part or all of virtual scenes and virtual characters located in the virtual scenes, and the method specifically may include the following steps:

Step 501, obtaining one or more interactable objects in the virtual scene according to the virtual character;

in a preferred embodiment of the present invention, the step 501 comprises the following sub-steps:

judging whether the type of the object in the virtual scene is consistent with a preset type; the types include combat types and interaction types;

if yes, determining the object as a preliminary screening object;

The preset type is set according to the playing method or action to be executed by the player or AI, when the executed playing method is a combat playing method, such as releasing attack skills and defending attack from enemies, the type can be determined to be a combat interaction type, when the executed playing method is a non-combat playing method, such as giving articles and a carrying case, the type at the moment is determined to be a non-combat interaction type, whether the objects in the virtual scene are consistent with the preset type is determined, and when the objects are consistent with the preset type, the objects can be determined to be primary screening objects. For example, when the predetermined type is a combat interaction class, then one or more enemy persons in the virtual scene are determined to be preliminary screening objects.

In a game, generally, the interaction between a player or an AI-controlled character and an interactable object has a distance limitation, for example, when the player-controlled character performs an interactive operation of attacking an enemy, the player can only attack the enemy with the distance between the player and the character within an attack range, if the attack range of the character is 1 meter, the enemy with the distance between the player and the character controlled by the player within 1 meter can be attacked and the enemy beyond 1 meter is not affected by the attack. Therefore, in order to prevent locking of the object exceeding the interactable distance, whether the distance between the primary screening object and the virtual character is smaller than a preset threshold value is judged, and if yes, the primary screening object is considered to be influenced by the interaction operation of the virtual character. Further, in order to make the interaction in the game more in line with the logic of real life, the input degree of the player is improved, after it is determined that the primary screening object can be affected by the interaction operation of the virtual character, whether a shielding object exists between the primary screening object and the virtual character is also required to be detected, if the shielding object exists, the interaction operation is considered to be unable to be completed, for example, when the attack operation is executed, a wall is spaced between the character controlled by the player and the enemy in the attack range, according to the logic of real life, the character cannot know that the enemy exists behind the wall or can not attack the enemy behind the wall through the wall, so that the primary screening object can be determined as the interactable object only when the shielding object does not exist between the virtual character and the primary screening object. It should be noted that the detection mode may be selected according to the needs of those skilled in the art, for example, a radiation detection mode may be adopted, which is not limited by the present invention.

Step 502, constructing a spherical coordinate system by taking the virtual character as a center;

a spherical coordinate system is constructed with a virtual character controlled by a player or AI as the origin of coordinates.

Step 503, obtaining three-dimensional cartesian coordinates of the interactable object based on the position information;

the three-dimensional cartesian coordinate system passes through a fixed point and is used as three mutually perpendicular axes, which are all about the fixed point as the origin of coordinates and generally have the same length units, and these three axes are respectively called an x-axis (horizontal axis), a y-axis (vertical axis), and a z-axis (vertical axis), and are collectively referred to as coordinate axes. The x-axis and y-axis are typically arranged in a horizontal plane, while the z-axis is a plumb line. And obtaining the three-dimensional Cartesian coordinates of the interactable object in the virtual scene through the obtained position information.

Step 504, converting the three-dimensional cartesian coordinates into spherical coordinates in the spherical coordinate system;

specifically, as shown in fig. 6, a point P is the origin of coordinates where the virtual character is located, a point a is the three-dimensional cartesian coordinates of an interactable object, and a point B is spherical coordinates in a spherical coordinate system converted from the three-dimensional cartesian coordinates of the interactable object. Spherical coordinates can be expressed asWherein r represents the distance between the point A and the origin of coordinates, θ represents the angle between the directional line BP and the positive direction of the z axis, and +. >Representing the angle between the projection of the directed line segment BP on the xy plane and the positive x-axis. Assume that the three-dimensional Cartesian coordinates of point A are (x _a ，y _a ，z _a ) The three-dimensional cartesian coordinates of the point P are (x _p ，y _p ，z _p ) The three-dimensional Cartesian coordinate value of the point A minus the three-dimensional Cartesian coordinate value of the point P is (x) _a-p ，y _a-p ，z _a-p ) Taking point a as an example, point a is converted to point B according to the following formula:

the three-dimensional cartesian coordinates of each interactable object are converted into spherical coordinates.

Step 505, determining target spherical coordinates according to the spherical coordinates of the virtual character and the interactable object;

in a preferred embodiment of the present invention, the step 505 comprises the following sub-steps:

After the target spherical coordinates are determined, by comparing the angle difference and the distance between the spherical coordinates of the virtual character and the one or more interactable objects as the origin of the spherical coordinates system, the target spherical coordinates which are most suitable as the interactable objects of the locking objects can be determined from the spherical coordinates of the plurality of interactable objects according to the preset comparison rule.

In a preferred embodiment of the present invention, the step of determining the first target spherical coordinates based on the first angle difference and the first distance between the spherical coordinates of the virtual character and the interactable object further comprises:

In the embodiment of the invention, the virtual character can be the virtual character controlled by the AI, and since the locked object does not exist at the beginning, the virtual character controlled by the AI needs to be projected as a point on the spherical surface in front, so as to fictitiously construct a currently locked interactable object. An optimal lock object is then selected based on the interactable object. Therefore, according to the direction faced by the virtual character, the projected spherical coordinates of the virtual character on the unit spherical surface of the spherical coordinate system can be obtained, then the projected spherical coordinates are used as the origin, the mapped spherical coordinates of the interactable object are obtained, the angle difference and the distance between the interactable object and the target character can be determined by adopting the mapped spherical coordinates, all the mapped spherical coordinates are traversed, and the mapped spherical coordinates of the most suitable locking object, namely the first target spherical coordinates, can be selected from the projected spherical coordinates according to the angle difference and the distance.

Specifically, if the spherical coordinates of the virtual character projected onto the unit sphere directly in front of the virtual character are set as point C, the spherical coordinates of the interactable object are mapped to mapped spherical coordinates with the point C as the originThe formula of (2) is:

when (when)

When (when)

Wherein,representing the component of the spherical coordinates of the interactable object in the horizontal direction. />Representing the component of point C in the horizontal direction. />Representing the mapped new value. According to the formula, +.>The value of (2) is [ -pi, pi]And thus ensures that the value of point C is 0,and the optimal point is convenient to select according to the size of the coordinate value.

Similarly, θ in the mapped spherical coordinates can be calculated according to the following formula ₂ Is the value of (1):

θ ₂ ＝θ ₁ -θ _c ；

when (theta) ₂ ＞π)，θ ₂ ＝θ ₂ -2π；

When (theta) ₂ ＜π)，θ ₂ ＝θ ₂ +2π；

Wherein θ ₁ Representing the component of the spherical coordinates of the interactable object in the vertical direction. θ _c Representing the component of point C in the vertical direction, θ ₂ Representing the mapped new value.

After the mapped spherical coordinates of the interactable object are obtained, a first angle difference and a first distance between the interactable object and the virtual character may be calculated by the following formula:

wherein Angle is the Angle difference, abs represents the absolute value, and the distance r is a known parameter.

In a preferred embodiment of the present invention, the step of traversing the first mapped spherical coordinates and determining the first target spherical coordinates according to the first angle difference and the first distance further comprises the sub-steps of:

And judging whether the difference value between the angle differences corresponding to the mapped spherical coordinates exceeds a preset threshold value by traversing the mapped spherical coordinates, if so, reserving the mapped spherical coordinates with smaller angle differences, continuing to compare with the rest mapped spherical coordinates until the difference value is within the preset threshold value, and comparing the distance between the two mapped spherical coordinates and the virtual character, and selecting the mapped spherical coordinates with smaller distance, wherein the mapped spherical coordinates are the spherical coordinates of the locked object, namely the target spherical coordinates.

Specifically, the mapping spherical coordinates may be traversed and the target spherical coordinates determined as follows:

(1) If the first mapped spherical coordinate currently traversed, there are:

BestIdx＝Idx；

BestAngle＝Angle；

BestDist＝r；

and (2) when the condition that the index of the current traversal is equal to the index of the current traversal, each mapping spherical coordinate has a corresponding index, and the first mapping spherical coordinate of the current traversal is satisfied, repeating the step (1). If not, entering the next step, namely, the step (2):

(2) When BestAngle-Angle > MinLockSwitchAngle, then there are:

BestIdx＝Idx；

BestAngle＝Angle；

BestDist＝r；

repeating the step (2), otherwise, entering the step (3)

Where MinLockSwitchAngle represents an angle threshold of spatial angular proximity of two interactable objects, which may take 1 as an example. In the step, the difference operation is performed by using the traversed angle difference between the first mapped spherical coordinate and the second mapped spherical coordinate, when the result is larger than the preset angle threshold, the angle difference between the first mapped spherical coordinate and the origin of coordinates is considered to be larger than the angle difference between the second mapped spherical coordinate and the origin of coordinates, so that the second mapped spherical coordinate is used as the current optimal mapped spherical coordinate, the index of the second mapped spherical coordinate is used as the current optimal target index, the angle difference of the second mapped spherical coordinate is used as the current optimal angle difference, the distance of the second mapped spherical coordinate is used as the current optimal distance, the process is repeated, namely, the traversing of the mapped spherical coordinates is continued, and when the result is smaller than the preset angle threshold, the step (3) is entered.

(3) When abs (BestAngle-Angle) < MinLockSwitchAngle and BestDist > r, then there are:

BestIdx＝Idx；

BestAngle＝Angle；

BestDist＝r；

returning to the step (2) until all the mapped spherical coordinates are traversed.

When the difference between the current optimal angle difference and the angle difference of the currently traversed mapping spherical coordinates is smaller than a preset angle threshold and the current optimal distance is larger than the distance of the currently traversed mapping spherical coordinates, namely, the spatial distance between the current optimal interactable object and the interactable object corresponding to the currently traversed mapping spherical coordinates is similar, but the distance between the current optimal interactable object and the coordinate origin, namely, the virtual role is far, so that the currently traversed mapping spherical coordinates are used as optimal mapping spherical coordinates, the index thereof is used as a current optimal target index, the angle difference thereof is used as the current optimal angle difference, the distance thereof is used as the current optimal distance, then the step (2) is returned until all the mapping spherical coordinates are traversed, the interactable objects are screened according to the spatial angles, the preferred angle difference is the smallest, if the angle difference is close, the distance is selected, and the finally obtained optimal mapping spherical coordinates are the first target spherical coordinates corresponding to the selected locking objects.

And step 506, taking the interactable object corresponding to the target spherical coordinate as a locking object of the virtual character and locking.

After the target spherical coordinates are determined, the interactable object corresponding to the target spherical coordinates can be confirmed to be a locking object with the optimal virtual character, and the operation of locking the object is executed.

In a preferred embodiment of the present invention, the virtual character is a player-controlled character, and the method further comprises:

Specifically, when the player wants to switch the locked object when the virtual character controlled by the player has a locked object in the virtual scene, the player can input a direction instruction, for example, through a keyboard key or a handle rocker, for example, after the player attacks the locked enemy in a battle of the game, according to the judgment of the battle situation, the player wants to attack another enemy on the left side of the locked enemy, and at this time, the player can press a left direction key on the keyboard to switch the locked enemy to the other enemy. After receiving the direction instruction input by the player, acquiring the spherical coordinates of the locked object, and taking the spherical coordinates as the origin, acquiring the mapped spherical coordinates of the interactable object after the spherical coordinates of the interactable object are mapped, wherein the specific calculation mode can refer to the mapping spherical coordinates of the interactable object mapped to the mapped spherical coordinates taking the point C as the origin The angle difference and the distance between the interactable object and the object locked by the target role can be determined by adopting the mapping spherical coordinates, and the specific calculation mode can refer to the mapping spherical coordinates> And traversing all the mapping spherical coordinates in a calculation mode of the angle difference and the distance between the mapping spherical coordinates and the target role, selecting the most suitable mapping spherical coordinates of the locked object according to the angle difference and the distance, specifically, judging whether the difference value between the angle differences corresponding to the mapping spherical coordinates exceeds a preset threshold value by traversing the mapping spherical coordinates, if so, reserving the mapping spherical coordinates with smaller angle difference, continuing to compare with the rest mapping spherical coordinates until the difference value is within the preset threshold value, comparing the distance between the mapping spherical coordinates and the virtual role, and selecting the mapping spherical coordinates with smaller distance, wherein the mapping spherical coordinates are the spherical coordinates of the locked object, namely the spherical coordinates of the second target.

Similarly, if y ₁ Greater than 0, then need to be eliminatedA target smaller than 0, namely selecting screening mapping spherical coordinates with components in the horizontal direction larger than and/or equal to zero; if y ₁ If the ratio is less than 0, the +.>And selecting a screening mapping spherical coordinate with a component smaller than and/or equal to zero in the horizontal direction as a target with a value larger than 0, and finally obtaining the screening mapping spherical coordinate after the vertical coordinate selection.
