Background

Air combat games are a common form of game in which a player needs to know the direction of flight of an aircraft being maneuvered to determine the direction of flight of the next step. In the air combat game, there is generally no explicit horizon reference, so that the player cannot know whether the current flight direction is consistent with the expected direction.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application, and it should be understood that the drawings in the present application are for the purpose of illustration and description only and are not intended to limit the scope of the present application. In addition, it should be understood that the schematic drawings are not drawn to scale. A flowchart, as used in this disclosure, illustrates operations implemented according to some embodiments of the present application. It should be understood that the operations of the flow diagrams may be implemented out of order and that steps without logical context may be performed in reverse order or concurrently. Moreover, one or more other operations may be added to or removed from the flow diagrams by those skilled in the art under the direction of the present disclosure.

In addition, the described embodiments are only some, but not all, embodiments of the application. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present application.

In order to enable a person skilled in the art to use the present disclosure, the following embodiments are presented in connection with a specific application scenario "game scenario of a virtual aircraft". It will be apparent to those having ordinary skill in the art that the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the application. Although the application is described primarily around a game scenario for a virtual aircraft, it should be understood that this is only one exemplary embodiment. For ease of description, the following embodiments of the present application will simply refer to virtual aircraft as aircraft.

It should be noted that the term "comprising" will be used in embodiments of the application to indicate the presence of the features stated hereafter, but not to exclude the addition of other features.

In the prior art, the method of assisting the player to know the flying direction by means of the direct displacement of the sight, although the player can know the flying direction to a certain extent, in this way, the direction of the sight is relative to the aircraft itself. For example, if the abdomen of the aircraft is facing upwards, the sight is displaced upwards. This approach does not indicate a change in direction of the aircraft relative to the ground or sky. For example, when the aircraft belly is facing up, the sight is displaced upward, however, when the aircraft is flying toward the ground, the direction of flight of the aircraft cannot be effectively indicated with the direction of displacement of the sight. When the field of view in the game environment is good, the player can judge the direction of the aircraft relative to the ground or sky through naked eyes. However, when the field of view of the game environment is poor, for example, the cloud layer around the aircraft is thick, the field of view is blocked, the player cannot judge the direction of the aircraft relative to the ground or the sky through naked eyes, and meanwhile, no indication mark capable of indicating the direction of the aircraft relative to the ground or the sky exists, so that the aircraft may crash.

Based on the above problems, the embodiment of the application provides a direction indication method in a game, which can draw and display a direction indication mark in real time by utilizing the reference direction change of a reference surface when a three-dimensional virtual scene rotates relative to a virtual object, so as to prompt the relative angle change between a plane where the virtual object is positioned and the reference surface, thereby enabling a player to accurately judge the direction of the virtual object relative to the reference surface by utilizing the direction indication line in a game scene with poor visual field, and avoiding the problems of crash and the like.

Before describing the technical scheme of the application, the concepts related to the application are explained first.

In a game scene, two coordinate systems are involved, namely a local coordinate system and a world coordinate system. The local coordinate system may also be referred to as a relative coordinate system, and may represent a relative position and direction of a certain virtual object or position relative to another virtual object or position in the virtual scene. In particular, in the application, the relative coordinate system of the aircraft itself can be established with reference to the aircraft. In this relative coordinate system, each coordinate represents a relative coordinate with respect to the aircraft, respectively. For example, a relative coordinate system of the aircraft is constructed with a certain point in the aircraft as an origin, a plane in which the aircraft is located as a plane in which the x-axis and the y-axis are located, and a line passing through the origin and perpendicular to the plane in which the x-axis and the y-axis are located as a z-axis. Using the relative coordinate system of the aircraft, the coordinates of the various vertices and other locations in the aircraft relative to the aircraft may be determined. For example, upon completion of the aircraft rendering, the relative coordinate system of the aircraft may be utilized to determine the coordinates of the vertices of the aircraft and render the aircraft on those coordinates.

In the above-described local coordinate system, when a virtual object has a parent object, the position of the parent object relative to its own parent object is not changed all the time as a child object regardless of the change in the positional rotation scaling of the parent object. When a virtual object does not have a parent object, the world can be regarded as its parent object, and all position changes in the world can be regarded as relative position changes with the world, in which case the local coordinates of the virtual object are identical to the world coordinates because the world coordinate system and the local coordinate system of the world are coincident. In particular, according to the application, a parent object does not exist in the three-dimensional virtual scene, and a world coordinate system is established by taking the whole three-dimensional virtual scene as a reference. When the aircraft flies in the three-dimensional virtual scene, the position change of the aircraft relative to the three-dimensional virtual scene can be determined under the world coordinate system. In particular, the change in position of an aircraft during flight may be represented by three attitude parameters, including: pitch angle (pitch), yaw angle (yaw), and roll angle (roll), wherein pitch angle represents the angle of rotation of the aircraft about the x-axis of the world coordinate system, yaw angle represents the angle of rotation of the aircraft about the y-axis of the world coordinate system, and roll angle represents the angle of rotation of the aircraft about the z-axis of the world coordinate system.

The relative coordinate system and the world coordinate system are three-dimensional coordinate systems, and the graphical user interface displayed on the game screen is a two-dimensional interface. There is a virtual camera in the game, which is used to shoot three-dimensional virtual scenes and aircrafts in the world coordinate system from a specific viewing angle, and to project the shot images into a two-dimensional graphical user interface.

In the first mode, the lens angle of the virtual camera is fixed and stays at a fixed position coordinate in the world coordinate system. In the continuous images shot by the virtual camera from the view angle, the position of the three-dimensional virtual scene is unchanged, and the position of the aircraft is changed. In the second way, the lens angle of the virtual camera is locked with the aircraft, i.e. the lens angle of the virtual camera changes with the flight of the aircraft and remains unchanged with respect to the aircraft at all times. For example, the lens angle of the virtual camera is always directed in the nose direction of the aircraft. In the continuous images shot by the virtual camera in this way, the position of the aircraft remains unchanged, and the position of the three-dimensional virtual scene changes.

As an alternative embodiment, the present application is based on the above second mode to realize display of game screen. It will be appreciated that in this second approach, the position of the aircraft remains unchanged and the position of the three-dimensional virtual scene changes, both with respect to the world coordinate system. In particular, when the lens angle of the virtual camera changes as the aircraft flies, the position of the aircraft in the world coordinate system remains unchanged, while the position of the three-dimensional virtual scene in the world coordinate system changes. Wherein the change in the position of the three-dimensional virtual scene is determined based on the player's control instructions for the aircraft. The following embodiments of the application are based on the second way described above, detailing how the direction indication of the aircraft is implemented in a graphical user interface. In addition, for the aircraft itself, the coordinates of the vertices of the aircraft may be determined using its relative coordinate system, and the rendering of the aircraft in the graphical user interface may be performed by projection. The present application is not separately described with respect to a process for completing an aircraft rendering using a relative coordinate system.

The direction indication method in the game in one embodiment of the application can be run on a local terminal device or a server. When the direction indication method in the game runs on the server, the method 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. In the running mode of the cloud game, a running main body of the game program and a game picture presentation main body are separated, the storage and running of the direction indication method in the game are completed on a cloud game server, and the function of a client device is used for receiving and sending data and presenting game pictures, for example, the client device can be a display device with a data transmission function close to a user side, such as a mobile terminal, a television, a computer, a palm computer and the like; but the cloud game server which performs information processing is a cloud. When playing the game, the player operates the client device to send an operation instruction to the cloud game server, the cloud game server runs the game according to the operation instruction, codes and compresses data such as game pictures and the like, returns the data to the client device through a network, and finally decodes the data through the client device and outputs the game pictures.

In an alternative embodiment, taking a game as an example, the local terminal device stores a game program and is used to present a game screen. The local terminal device is used for interacting with the player through the graphical user interface, namely, conventionally downloading and installing the game program through the electronic device and running. The manner in which the local terminal device provides the graphical user interface to the player may include a variety of ways, for example, may be rendered for display on a display screen of the terminal, or provided to the player by holographic projection. 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.

In a possible implementation manner, the embodiment of the application provides a direction indication method in a game, and a graphical user interface is provided through terminal equipment, wherein the terminal equipment can be the aforementioned local terminal equipment or the aforementioned client equipment in the cloud interaction system.

The direction indication method in the game of the present application will be described in detail by means of a plurality of examples.

Fig. 1 is a flow chart of a direction indication method in a game according to an embodiment of the present application, and it should be noted that the game display method provided by the present application is not limited to the specific order shown in fig. 1 and described below. It should be understood that, in other embodiments, the sequence of some steps in the game display method provided by the present application may be interchanged according to actual needs, or some steps may be omitted or deleted. As shown in fig. 1, the method includes:

s101, acquiring a first reference direction of a reference surface in a three-dimensional game scene.

Optionally, the three-dimensional game scene to which the present application is applicable may include, for example: air combat game scenes, water game scenes, and the like. In an air combat game scenario, the aforementioned virtual object, the aircraft, is involved. In a water play scenario, virtual objects such as submarines that move in the water may be involved. Accordingly, the reference surface described in the present application may include: level, ground or sea surface. It is understood that the level, ground and sea surface refer to the level, ground and sea surface in a three-dimensional virtual scene. Wherein, the horizontal plane may refer to a plane parallel to the ground or a plane parallel to the ground. For example, in the air combat game scene and the water game scene, the reference surface may be any one of a horizontal plane, a ground plane, and a sea surface.

For convenience of description, the following embodiments of the present application are explained with reference to a virtual object as an aircraft.

Alternatively, the reference direction of the reference plane may refer to a direction having a fixed positional relationship with the reference plane. In the world coordinate system, after the coordinate information of the reference plane is determined, the coordinate information of the reference direction can be determined accordingly. Taking an air combat game scene as an example, a player controls the aircraft to fly, because the lens view angle of the virtual camera locks the aircraft, the position of the aircraft is kept unchanged in the flying process of the aircraft, and the position of the three-dimensional virtual scene is correspondingly changed along with the control instruction of the player, and the position of the reference surface is correspondingly changed. The terminal device or the server can monitor whether the player sends out the control instruction in real time, and execute the method steps of the application under the triggering of the player sending out the control instruction. The first reference direction may be a reference direction of the reference plane at a start time of the player issuing the manipulation instruction, that is, an initial reference direction of the reference plane.

S102, displaying a direction indication mark pointing to the first reference direction at a preset position of the graphical user interface, wherein the direction indication mark is used for prompting a relative angle between a plane where the virtual object is located and the reference plane.

Alternatively, the preset position may be a position having a fixed relative positional relationship with the virtual object. And displaying a direction indication mark pointing to the first reference direction on the preset position, wherein the first reference direction is a direction with a fixed position relation with the reference surface, so that the direction indication mark pointing to the first reference direction can show the position information of the reference surface, and the position of the virtual object is unchanged, so that the direction indication mark can prompt the relative angle between the plane where the virtual object is positioned and the reference surface.

And S103, receiving a control instruction aiming at the virtual object, controlling the rotation of the three-dimensional virtual scene relative to the virtual object, and determining a second reference direction of the reference surface after the relative rotation.

As mentioned above, the position change of the aircraft during flight can be represented by three attitude parameters, namely pitch angle, yaw angle and roll angle, respectively, that is to say the position change of the aircraft can be reflected in the changes of pitch angle, yaw angle and roll angle. After the player sends out the control command, the terminal equipment or the server can know the change information of the pitch angle, the yaw angle and the roll angle based on the control command, and then the terminal equipment can convert the change information of the pitch angle, the yaw angle and the roll angle of the aircraft into the change information of the pitch angle, the yaw angle and the roll angle of the three-dimensional virtual scene so as to control the rotation of the three-dimensional virtual scene relative to the virtual object.

Along with the rotation of the three-dimensional virtual scene, the reference surface positioned in the three-dimensional virtual scene correspondingly rotates, and the terminal equipment can determine a second reference direction after relative rotation by utilizing the position to which the reference surface rotates and the fixed position relation between the reference surface and the reference direction.

It should be understood that the positional relationship between the second reference direction and the reference surface after rotation is still the positional relationship between the first reference direction and the reference surface before rotation.

And S104, adjusting the indication direction of the direction indication mark according to the second reference direction so that the direction indication mark points to the second reference direction to prompt the relative angle change between the plane where the virtual object is located and the reference plane.

When the reference surface rotates to a new position along with the rotation of the three-dimensional virtual scene, the second reference direction also changes relative to the first reference direction, so that the indication direction of the direction indication mark can be adjusted according to the second reference direction. Specifically, before the adjustment, the direction indication mark points to the first reference direction, and after the adjustment, the direction indication mark points to the second reference direction, and the change from the first reference direction to the second reference direction can clearly prompt the relative angle change between the plane where the virtual object is located and the reference plane.

Fig. 2 is a schematic diagram of an interface of a direction indication mark, as shown in fig. 2, a point a represents a preset position in a graphical user interface, at a starting moment when a player sends a control command, the direction indication mark pointing to a first reference direction is a line segment AB formed by a point a and a point B, when the control command of the player is responded, the three-dimensional virtual scene rotates, and accordingly, the direction indication mark pointing to a second reference direction is a line segment AC formed by a point a and a point C, and a change from AB to AC can indicate a relative angle change between a plane where a virtual object is located and a reference plane.

In this embodiment, after a first reference direction of a reference plane in a three-dimensional game scene is obtained, a direction indication identifier pointing to the first reference direction is displayed at a preset position of a graphical user interface, where the direction indication identifier can represent a relative angle between a plane where a virtual object is located and the reference plane. After the player sends out the control instruction, the player can respond to the control instruction to control the rotation of the three-dimensional virtual scene relative to the virtual object, the rotation of the three-dimensional virtual scene causes the rotation of the reference surface, and when the reference surface rotates, the reference direction with a fixed position relation with the reference surface changes, so that a changed second reference direction can be obtained, and the indication direction of the direction indication mark is adjusted according to the second reference direction, so that the relative angle change between the plane where the virtual object is located and the reference surface is prompted. Through the process, the relative angle change of the virtual object and the reference surface such as the ground, the sea surface and the like can be displayed to the player in real time, so that the player can accurately judge the angle change of the virtual object relative to the reference surface by utilizing the direction indication mark in a game scene with poor visual field, and the problems of crash and the like are avoided.

As an alternative embodiment, the first reference direction and the second reference direction are normal directions of the reference plane; or the first reference direction and the second reference direction are tangential directions of the reference plane.

In one embodiment, the normal line is a straight line always perpendicular to a certain plane. In the present application, the reference direction of the reference surface may always be the normal direction of the reference surface. Specifically, the reference plane and the reference direction have a fixed positional relationship, and the reference direction points to the normal direction of the reference plane regardless of how the reference plane rotates.

In another way, geometrically, a tangent line refers to a straight line that just touches a point on a curve. Specifically, when a tangent line passes a point on a curve (i.e., a tangent point), the direction of the tangent line is the same as the direction of the point on the curve. In planar geometry, a straight line having only one common intersection with a circle is referred to as a tangent to the circle. In the present application, the reference direction of the reference plane may always be the tangential direction of the reference plane. Specifically, the reference plane and the reference direction have a fixed positional relationship, and the reference direction is directed in a tangential direction of the reference plane regardless of how the reference plane rotates.

In this embodiment, since the normal line and the tangent line both represent the direction line having a fixed positional relationship with the reference plane, and the normal line is perpendicular to the reference plane, the tangent line passes through the reference plane, and the positional relationship with the reference plane is simple, when the direction mark pointing to the reference line is drawn based on the reference plane, the drawing is performed based on the normal line or the tangent line, so that the complexity of calculation can be reduced, and the performance of the system can be improved.

Hereinafter, a process of displaying the direction indication mark at the preset position of the aforementioned gui will be described.

As an alternative embodiment, a sight may be included on the graphical user interface for prompting the aiming direction of the virtual object. Alternatively, while the position of the virtual object in the graphical user interface remains unchanged, the position of the sight in the graphical user interface also remains unchanged, and there may be a fixed relative position between the sight and the virtual object. Illustratively, the position of the sight has a predetermined fixed correspondence with the position of the projectile firing port of the aircraft. For example, assuming that the position of the projectile firing port projected onto the graphical user interface is (x, y), the position of the sight may be (x+a, y), where a may be a preset fixed value.

Based on the sight, the display of the direction indication mark can be completed.

Alternatively, the direction indication mark may be a direction indication line, where the direction indication line includes a start point and an auxiliary line segment.

An alternative to the above step S102 includes:

And drawing the direction indication line at the preset position by taking the sight as the starting point of the direction indication line and the first reference direction as the auxiliary line segment direction of the direction indication line.

The preset position may be a position where the pointer is located. And drawing the auxiliary line segment along the first reference direction by taking the sight glass as a starting point of the direction indication line at the preset position, so that the direction indication line is displayed on a graphical user interface.

Referring to fig. 2, a point a is a sight position of the aircraft, and a direction indication line drawn along the first reference direction is as shown in AB in fig. 2, with the sight position as a starting point.

In this embodiment, since the sight is used to prompt the aiming direction of the virtual object, and is fixed in the relative position of the sight and the virtual pair, and is located right in front of the virtual object, that is, the sight is located at the position most visible in the field of view of the player, the sight is used as the starting point of the direction indication line, and the direction indication line is drawn along the first reference direction, so that the player can quickly look up the direction indication line.

On the basis of the direction indication line drawn to point to the first reference direction based on the sight, the direction indication line drawn to point to the second reference direction based on the sight can be correspondingly drawn.

Specifically, an alternative manner of the step S104 includes:

The specific implementation process is identical to the process of drawing the direction indication mark pointing to the first reference direction, and the difference is that the second reference direction is taken as the indication direction of the auxiliary line segment in this embodiment, which can be seen in the above embodiment, and details are not repeated here.

Optionally, in the above embodiment, the length of the auxiliary line segment is positively correlated with the relative distance between the virtual object and the reference plane.

The length of the auxiliary line segment may be obtained by calculating a product of a relative distance between the virtual object and the reference surface and a preset coefficient.

The length of the auxiliary line segment is positively correlated with the relative distance between the virtual object and the reference surface, when the relative distance between the virtual object and the reference surface is larger, the length of the auxiliary line segment is longer, otherwise, when the relative distance between the virtual object and the reference surface is smaller, the length of the auxiliary line segment is shorter, so that the direction pointing line can be matched with the actual distance, and the problem that the direction pointing line is too long to exceed the reference surface when the distance is smaller or the direction pointing line is too short to effectively point the relative angle of the reference surface when the distance is larger is avoided.

As an alternative implementation manner, when the direction indication line is drawn, a specific mark can be added on the basis of the direction indication line, so that a player can easily and clearly see the direction indication line. It should be noted that the following specific marking method may be applied to the process of drawing the direction indication line pointing to the first reference direction or the process of drawing the direction indication line pointing to the second reference direction.

Specifically, the method further comprises the following steps:

And determining a circular area by taking the vertex, far away from the sight, of the auxiliary line segment as a circle center, and drawing an arc mark along the circumference of the circular area.

Alternatively, the radius of the circular area may be positively correlated with the length of the auxiliary line segment. For example, the longer the auxiliary line segment, the larger the radius of the circular region, and the shorter the auxiliary line segment, the smaller the radius of the circular region.

Fig. 3 is a schematic diagram of drawing an arc mark on an auxiliary line segment, as shown in fig. 3, a point a is a sight position of an aircraft, the auxiliary line segment is AB, then a vertex far away from the sight in the auxiliary line segment is taken as a point B, a circular area can be determined by taking the point B as a center of a circle, the arc mark as shown in fig. 3 is drawn along the circumference of the circular area, and a chord corresponding to the arc mark is perpendicular to the auxiliary line segment.

As described above, in the present application, the lens angle of the virtual camera locks the aircraft, changing continuously as the aircraft flies. Based on this, as an optional embodiment, when the rotation of the three-dimensional virtual scene relative to the virtual object is controlled in the step S103, the following procedure may be specifically performed:

Illustratively, the virtual object is always centered on the graphical user interface and always remains top up.

Hereinafter, a specific control procedure for controlling the rotation of the three-dimensional virtual scene with respect to the virtual object in step S103 of the foregoing embodiment will be described.

Fig. 4 is another flow chart of a direction indication method in a game according to an embodiment of the present application, as shown in fig. 4, an alternative manner of the step S103 includes:

S401, based on the control instruction, the rotation direction and the rotation angle of the three-dimensional virtual scene relative to the virtual object are obtained.

Optionally, after the player sends out the control instruction, the terminal device or the server first knows the rotation direction and the rotation angle of the virtual object. For example, the player issues a control command to turn the aircraft 90 degrees to the right, indicating that the direction and angle of rotation of the aircraft are to the right and 90 degrees, respectively. On the basis, the rotation direction and the rotation angle of the virtual object can be converted, and the rotation direction and the rotation angle of the three-dimensional virtual scene relative to the virtual object can be obtained. For example, if the rotation direction and rotation angle of the aircraft are respectively right and 90 degrees, the three-dimensional virtual scene is left with respect to the rotation direction of the virtual object, and the rotation angle is 90 degrees.

It should be noted that, because the attitude of the aircraft during flight involves the pitch angle, the roll angle and the yaw angle, the rotation direction and the rotation angle of the virtual object obtained based on the control instruction described above include the rotation direction and the rotation angle corresponding to the pitch angle, the rotation direction and the rotation angle corresponding to the roll angle and the rotation direction and the rotation angle corresponding to the yaw angle, respectively, and accordingly, the rotation direction and the rotation angle of the three-dimensional virtual scene relative to the virtual object also include the rotation direction and the rotation angle corresponding to the pitch angle, and the rotation direction and the rotation angle corresponding to the roll angle and the rotation direction and the rotation angle corresponding to the yaw angle.

S402, controlling the three-dimensional virtual scene to rotate by the rotation angle along the rotation direction, and obtaining a reference surface after relative rotation and a second reference direction of the reference surface after rotation.

Optionally, controlling the rotation angle of the three-dimensional virtual scene along the rotation direction may include controlling the three-dimensional virtual scene to rotate along the rotation direction thereof at a pitch angle, a roll angle and a yaw angle, and simultaneously tracking the reference surface in the three-dimensional virtual scene, and acquiring the rotated reference surface after the rotation is completed. Further, the second reference direction may be determined by using a fixed positional relationship between the reference surface and the reference direction.

Fig. 5 is a schematic diagram of a rotated reference plane and a second reference direction, and as shown in fig. 5, assuming that the rotated reference plane is a plane a and the position of the sight glass is a point M, the determined second reference direction is a direction indicated by a reference line N, and the direction is perpendicular to the plane a and is a normal direction of the plane a.

As described in the foregoing embodiments, when the field of view of the game environment is poor, the player cannot judge the direction of the aircraft with respect to the ground or sky by naked eyes, and thus, there may be a problem in that the aircraft crashes or the like. This may not be the case when the game environment is well-viewed. Thus, as an alternative embodiment, the following procedure may be performed before the above step S101.

Fig. 6 is a schematic flow chart of another method for indicating directions in a game according to an embodiment of the present application, as shown in fig. 6, before the step S101, the method may further include:

s601, displaying game content determined by a virtual camera of a game on a graphical user interface in real time, wherein the game content comprises the virtual object and the three-dimensional virtual scene.

S602, when the three-dimensional virtual scene does not comprise the reference surface, executing a step of acquiring a first reference direction of the reference surface.

It should be noted that, the three-dimensional virtual scene does not include the reference surface, which means that the reference surface is not displayed in the gui. For example, due to the coverage of the cloud layer, only the cloud layer is displayed in the graphical user interface, and the reference surface is not displayed any more.

When the three-dimensional virtual scene does not include the reference plane, the step S101 and the subsequent steps are performed to draw and display the direction indication mark in the gui.

Alternatively, after the step S601, if it is determined that the three-dimensional virtual scene includes the reference plane, the direction indication mark may be hidden.

In this embodiment, when it is determined that the three-dimensional virtual scene does not include the reference plane, the steps of acquiring the first reference direction and the subsequent steps are performed, so that the player can continuously learn the relative angle change of the virtual object with respect to the reference plane. When the three-dimensional virtual scene comprises the reference surface, a user can judge the relative angle change of the virtual object relative to the reference surface by naked eyes, and at the moment, the direction indication mark can be hidden in time, so that the interference to a player can be avoided, and the game experience of the player is improved.
