Example one

Fig. 1 is a schematic flow chart of a method for presenting a game scene in a shooting game, which is provided in an embodiment of the present application, and is suitable for a situation where a game scene is presented when a game character moves in a shooting game. The method can be executed by computer equipment loaded with shooting game software, the game scene presenting method in the shooting game can be integrated in the loaded shooting game software as a plug-in, and the method is realized by running the shooting game software, and the computer equipment can be composed of two or more physical entities or one physical entity. Generally, the computer device may be a notebook, a desktop computer, a smart tablet, and the like.

It should be noted that, in this embodiment, the information is collected and the game scene is changed by taking a frame as a unit, and the information obtained by operations such as obtaining, receiving, or determining under the current frame in this embodiment is uniformly prefixed by a name of "current", for example, the current position information may be regarded as the position information of a certain example object under the current frame; similarly, the information obtained by the operations of obtaining, receiving, or determining in the previous frame is collectively prefixed by the name of "previous", and as the above location information, the location information may be regarded as the location information that a certain instance object has in the current frame.

As shown in fig. 1, a method for presenting a game scene in a shooting game provided in this embodiment specifically includes the following steps:

s101, determining the current position information to be calibrated of the virtual camera according to the received current direction information and the previous position information of the set target point, wherein the current direction information is information input by a user for controlling a game role.

In this embodiment, the current direction information may be control information input by the user through the input device in order to control the movement or rotation direction of the game character, and the current direction information may specifically be information required by the user to control the change of the posture (the movement direction and the position of the game character after the movement) of the game character under the current frame.

In this embodiment, the game character may be a character that is selected by a user (game player) in advance after entering the shooting game, and various actions of the game character in the game are controlled by the user through input of information. For example, the user may control the actions of the game character through control information input through input devices such as a keyboard, a mouse, and a touch panel. The current direction information in this step is one of the control information input by the user.

For example, in a shooting game, a user may use a keyboard as an input device, so that the user may input control information on a game character by pressing one or two keys of several direction keys "±)" ↓ "±" ← "→" representing forward, backward, left turn, and right turn on the keyboard, thereby acquiring current direction information corresponding to a current frame, such as pressing the "±") key, the represented current direction information representing that the game character does not deflect left and right when moving forward and straight; pressing the "speak" and "→" keys at the same time may represent current direction information moving in a combined direction of both forward and rightward directions.

In this embodiment, in order to implement smooth following of the movement of the virtual camera relative to the game character, the present embodiment introduces a target point, where the target point can specifically understand a shake point for reducing the shake of the virtual camera, and the present embodiment can indirectly determine the position information of the virtual camera in each frame by determining the position information of the target point in each frame. The previous position information of the target point may be understood as position information of the target point in a previous frame of the current frame, and the previous position information may be specifically determined by the method provided in this embodiment when the previous frame is used as the current frame.

It should be noted that, assuming that the method provided in this embodiment is performed initially, the previous location information of the target point acquired in this step may default to the initial location information of the previous device, where the initial location information of the target point may preferably be: the starting moving direction and the starting coordinate position of the game role. That is, the initial coordinate position and the corresponding initial movement direction that the game character initially has after the start of the game mode of the shooting game may be the initial direction of the game character by default.

In addition, the game scene in the shooting game is rendered and presented mainly in real time through the virtual camera, and therefore, in order to achieve rendering and presentation of the current game scene where the game character is located, camera position information of the virtual camera needs to be determined in advance. After receiving the current direction information and acquiring the previous position information of the target point, the step may determine, by determining the current position information of the target point, the position information of the virtual camera, which is provided when the virtual camera changes with the change of the game role in the current frame, by combining the preset association relationship between the virtual camera and the target point. In this embodiment, first, the position information determined by the virtual camera in this step is recorded as the current position information to be calibrated.

S102, calibrating the current direction to be calibrated in the current position information to be calibrated, and obtaining the current camera position information corresponding to the virtual camera after calibration.

It should be noted that, in S101, when a game character changes based on current direction information at a current frame, the camera position information that the virtual camera should have after changing along with the game character can be obtained, and theoretically, smooth presentation of a game scene picture can be directly achieved through the camera position information of the virtual camera at the current frame, however, in practical applications, it is found that rendering presentation of a game scene is directly performed only by depending on the camera position information determined in S101, and a quasi-star at the center of a screen in the game scene may be shielded by the game character, thereby causing a problem that a player user cannot accurately shoot by depending on the quasi-star.

To solve the above problem, the present embodiment adds an operation of performing calibration processing on the current to-be-calibrated position information (camera position information) of the virtual camera obtained in S101 described above by this step. The current position information to be calibrated includes a current movement direction to be calibrated, which is required by the virtual camera to move under the current frame, and a current camera coordinate position where the virtual camera is finally located after moving, and the key influencing the final position of the virtual camera in the current position information to be calibrated is the current movement direction to be calibrated.

Therefore, in this step, the current camera position information provided after the virtual camera calibration can be obtained by the calibration adjustment of the current to-be-calibrated moving direction. For example, the calibration adjustment of the current movement direction to be calibrated in this step may be to adjust the current movement direction to be calibrated by a certain angle counterclockwise or clockwise.

S103, presenting the current game scene where the game role is located according to the current camera position information.

In this embodiment, after the virtual camera is corrected based on the camera position information obtained in S101 in S102 to obtain the current camera position information, the corresponding rendering data information may be called based on the current camera position information in this step, so that the rendering presentation of the current game scene where the game character is located is realized through the called rendering data.

Specifically, the virtual camera is controlled to perform pose transformation based on the current camera position information, corresponding game scenes are presented through the matched rendering data after the pose transformation, and a sight bead on which a player user depends in shooting in the shooting game is controlled to be displayed in the center of a screen of a terminal screen. Therefore, the visual effect that the picture of the game scene can be smoothly changed only by controlling the game character and the game character can not shield the sight bead displayed at the center of the screen is presented to the user.

The method for presenting the game scene in the shooting game comprises the steps of firstly, determining position information of a virtual camera when the virtual camera changes along with a game role by considering an additionally arranged target point for buffering, and accordingly smoothly presenting a game scene picture; meanwhile, the operation of calibrating the position information of the virtual camera determined based on the position information of the target point is added before the game scene is smoothly presented, and by adopting the position information of the virtual camera after calibration, the game scene can be smoothly presented when moving and changing along with the game role, the shielding of the game role on the sight bead at the center of the screen can be effectively avoided, the sight bead can be always presented in the visual field of the user, and therefore the effects of improving the shooting hit rate of the user and improving the game experience are achieved.

As an optional embodiment of the first embodiment of the present invention, in the optional embodiment, after the presenting the current game scene in which the game character is located according to the current camera position information, the optimizing further includes: and taking the next frame as a new current frame, returning to continuously execute the determination operation of the current position information to be calibrated of the virtual camera until the shooting end condition is met.

It can be understood that, in the present embodiment, the presentation of the game scene in the shooting game is mainly performed in units of frames, and the present embodiment mainly stands at the angle of the current frame to describe how to implement the process of smooth presentation of the game scene when the position of the virtual camera changes correspondingly due to the change of the pose of the game character controlled by the user. In consideration of the persistence of the shooting game in practical applications, the present embodiment needs to continuously realize the presentation of game scenes in each frame in the shooting game.

Therefore, in this optional embodiment, after the current game scene where the game character is located is presented according to the current camera position information, the next frame is taken as a new current frame, and then the determination operation that the virtual camera has the current position information to be calibrated under the new current frame is returned to be continuously performed, so that the game scene presenting operation provided in this embodiment is repeatedly performed. After the next frame is taken as a new current frame, the original current frame is equivalent to the previous frame, and the current position information of the target point in the original current frame can be taken as the current previous position information.

In this alternative embodiment, the end condition for circularly executing the present presentation operation may be that a shooting end condition is currently satisfied, where the shooting end condition may be that the game player ends the current shooting task, or that the game character has exhausted life value and no longer has shooting capability.

Example two

Fig. 2 is a schematic flow chart of a game scene presenting method in a shooting game according to a second embodiment of the present invention, where the second embodiment is optimized based on the above-mentioned embodiments, and in this embodiment, the determining of the current to-be-calibrated position information of the virtual camera according to the received current direction information and the previous position information of the set target point is further embodied as: determining the current position information of the target point according to the received current direction information and the last position information of the set target point; and determining the current position information to be calibrated of the virtual camera according to the current position information.

Meanwhile, the present embodiment further calibrates the current direction to be calibrated in the current position information to be calibrated, and obtains the current camera position information corresponding to the virtual camera after calibration, which is embodied as: extracting the current direction to be calibrated and the current camera coordinate position contained in the current position information to be calibrated to obtain the corresponding current calibration direction after the current direction to be calibrated is clockwise rotated to a set angle value; determining a current camera movement direction of the virtual camera from the current calibration direction; and determining the current camera moving direction and the current camera coordinate position as the current camera position information corresponding to the virtual camera after calibration.

In addition, the present embodiment further presents the current game scene where the game character is located according to the current camera position information, specifically as follows: controlling the virtual camera to change from a previous pose corresponding to previous camera position information to a current pose corresponding to the current camera position information; acquiring current rendering data corresponding to the virtual camera in the current pose; and presenting the current game scene where the game role is positioned on a terminal screen through the current rendering data, and controlling a sight for shooting aiming to be displayed at the central point of the terminal screen.

As shown in fig. 2, a method for presenting a game scene in a shooting game provided in the second embodiment of the present invention specifically includes the following operations:

the present embodiment embodies the determination operation of the current position information to be calibrated in the above embodiment as the following two steps S201 and S202. It can be seen that the determination of the current position information to be calibrated of the virtual camera under the current frame is related to the current position information of the target point under the current frame.

S201, determining the current position information of the target point according to the received current direction information and the last position information of the set target point.

In this embodiment, the current direction information is pose control information corresponding to the game character at the current frame, and the previous position information of the target point is position information determined when the target point moves along with the game character at the previous frame. In this embodiment, the association relationship between the current direction information of the game character and the previous position information of the target point and the current position information of the target point may be pre-established before the step is executed, and the step determines the current position information of the target point according to the known association relationship among the current direction information of the game character, the previous position information of the target point and the current position information of the target point.

The current position information may be specifically understood as a moving direction and a coordinate position to be reached, which the target point should have at present when moving along with the game character when the game character moves according to the current direction information input by the user.

For example, the association relationship between the current direction information of the game character and the previous position information of the target point and the current position information of the target point may be represented by a function, the function is designed to achieve smooth change of the position of the target point, and different functions may represent different association relationships of the three. The function formula may be a linear interpolation function of a known interpolation parameter, and in the function formula, information as a function value may be determined from the current direction information of the game character, and one of the argument values of the function may be determined from the previous position information, whereby a key data information for performing the determination of the current position information may be determined, thereby achieving the determination of the current position information.

Further, in this embodiment, the determining the current position information of the target point according to the received current direction information and the previous position information of the set target point may be embodied as:

and S1, acquiring the position information of the last character of the game character.

It is understood that the determination of the current position information of the target point is mainly related to the current character position information that the game character has after moving through the current direction information. In this embodiment, the received current direction information may actually correspond to the movement control information that the user should have when controlling the game character to move under the current frame. The present embodiment can control the game character to update the current character position information that should be possessed next to the current frame from the previous character position information possessed by the previous frame through the current direction information.

In order to determine the current point position information of the target point, the present embodiment may first obtain the previous character position information of the game character through the branching step, so as to determine the current character position information that the game character should have after moving according to the current direction information.

And S2, determining the current role position information of the game role according to the current direction information and the previous role position information.

After the previous role position information is obtained, the current role position information which the game role should have after moving according to the current direction information can be realized through the branching step.

For example, the direction included in the current direction information may be determined as the current character moving direction of the game character, a distance value that the game character can move within one frame time may be determined based on attribute information such as a moving speed or a moving acceleration set in advance for the game character, and a current character coordinate position at which the game character is controlled to change according to the current direction information may be determined based on the distance value in combination with the coordinate position at which the game character is located in the previous frame.

Further, the following operation of the present embodiment gives a concrete implementation of the current character position information.

Specifically, fig. 2a shows an implementation flowchart of determining the position information of the game character in the game scene presenting method according to the second embodiment of the present invention. As shown in fig. 2a, determining the current character position information of the game character according to the current direction information and the previous character position information specifically includes the following operations:

s21, regularizing the current direction information, and determining the regularized current direction information as the current role moving direction of the game role.

In this embodiment, the current direction information received at the current frame may be represented in a vector coordinate form, or in a matrix form or a quaternion form, and the specific form of the current direction information is not limited in this embodiment. In order to better quantize the current direction information, the present embodiment takes vectorization as an example, that is, this step may perform regularization processing on the received current direction information represented by vectorization, for example, a representation interval (-1,1) of vector coordinate values may be specified, so that the vector coordinate representing the current direction information is represented by one value in the (-1,1) interval.

In this step, the current direction information obtained after processing according to the set rule can be directly determined as the current role moving direction of the game role.

And S22, determining the change distance value of the game role moving along the current role moving direction according to the movement attribute information set relative to the game role and the previous role coordinate position in the previous role position information.

In this embodiment, the movement attribute information may specifically refer to information such as a movement speed and a movement acceleration that are preset with respect to a game character, and after the movement attribute information corresponding to the game character is acquired, a change distance value generated when the game character moves in the determined movement direction of the current character within the time length of the current frame may be determined by combining a previous character coordinate value in previous character position information corresponding to a previous frame of the game character.

S23, determining the current role coordinate position of the game role according to the change distance value, and recording the current role moving direction and the current role coordinate position as the current role position information of the game role.

In this embodiment, the change distance value may be considered as a distance value formed by the game character moving from the previous character coordinate position in the current character moving direction by a unit frame time length, and the coordinate position of the current character that the game character should have in the current frame may be determined by coordinate calculation based on the known previous character position coordinate, the current character moving direction, and the change distance value.

In the step, the determined moving direction and the coordinate position of the current role can be directly regarded as the position information of the current role of the game role under the current frame.

And S3, determining the current position information of the target point according to the current role position information and the previous position information.

In this embodiment, the current character position information corresponds to position information that a user should have after controlling a game character to change under a current frame, and a function expression that can represent an association relationship between a current character coordinate position in the current character position information, a previous point coordinate position in the previous position information, and a current point coordinate position in the current position information may be preset in consideration of a change of a target point following the change of the game character.

In the present branching step, a predetermined function may be directly called to obtain the current position information of the target point on the basis of the known current role position information and the previous position information, and for example, a linear interpolation function may be preferably adopted as a function representing the association relationship between the above three. In order to realize the smoothness of the change of the target point along with the pose of the game role, the present embodiment regards the current role coordinate position as a function value in the function formula, regards the previous point coordinate position in the previous position information as an independent variable, and can determine the current point coordinate position of the target point on the basis of the given interpolation parameter.

Further, the following operation of the present embodiment gives a concrete implementation of the current position information of the target point.

Fig. 2b is a flowchart illustrating an implementation of determining position information of a target point in a game scene presenting method according to a second embodiment of the present invention. As shown in fig. 2b, in this embodiment, the determining the current location information of the target point according to the current role location information and the previous location information may be embodied as:

and S31, extracting the current role moving direction and the current role coordinate position in the current role position information, and determining the current role moving direction as the current point moving direction of the target point.

In this step, the current role moving direction and the current role coordinate position contained in the current role position information can be extracted. The target point is a following of the game character, and thus the current character movement direction of the game character can be directly regarded as the current point movement direction of the target point.

And S32, taking the current role coordinate position as an objective function value, and substituting the objective function value and the last target point coordinate position in the last position information into a given linear interpolation function to obtain the current point coordinate position of the target point.

In the step, a pre-constructed linear interpolation function can be directly called, and the function calculation of the linear interpolation function is realized to determine the current point coordinate position of the target point. The interpolation parameters in the linear interpolation function can be set by a game designer according to different desired effects, for example, the speed of interpolation processing can be controlled by adjusting the magnitude of the interpolation parameters.

And S33, determining the current point moving direction and the current point coordinate position as the current position information of the target point.

The step can directly take the moving direction of the current point and the coordinate position of the current point as the current position information of the target point when the target point changes along with the game role under the current frame.

S202, determining the current position information to be calibrated of the virtual camera according to the current position information.

In this embodiment, the presentation of a game scene where a game character is located in a shooting game is related to a virtual camera following the game character, when the position of the game character changes, the position of the virtual camera changes correspondingly, the current position information of a target point introduced in this embodiment is combined with the position association relationship between the target point and the virtual camera, so that the camera position information that the virtual camera has when the virtual camera moves along with the game character under the current frame can be determined, and this embodiment records this camera position information as the current position information to be calibrated.

It should be noted that, in this embodiment, the position association relationship between the target point and the virtual camera may be set such that the virtual camera follows in the same direction at a position that is a fixed distance away from the target point, and therefore, after the current position information is determined, the current camera position information of the virtual camera may be determined by combining the fixed distance values set in advance corresponding to the two.

Further, the following operation of the present embodiment gives a concrete implementation of the current camera position information of the virtual camera.

Specifically, fig. 2c shows a flowchart for determining calibration position information of a virtual camera in the game scene presenting method according to the second embodiment of the present invention. As shown in fig. 2c, determining the current position information to be calibrated of the virtual camera according to the current position information specifically includes the following operations:

s2021, determining the current point moving direction in the current position information as the current direction to be calibrated of the virtual camera, and acquiring the current point coordinate position in the current position information.

It is to be understood that the virtual camera may be regarded as following the target point, and thus the moving direction of the virtual camera may be regarded as the same as the moving direction of the target point, and this step may directly determine the current point moving direction in the current position information as the current camera moving direction of the virtual camera. And simultaneously, the coordinate position of the current point included in the current position information can be extracted.

S2022, determining a target position which is a first set distance value away from the coordinate position of the current point along a direction opposite to the moving direction of the current point, and taking a coordinate corresponding to the target position as a current camera coordinate position of the virtual camera.

The method mainly comprises the steps of determining the current camera coordinate position of the virtual camera, specifically, the actual coordinate position of the virtual camera should be located behind a target point, so that the current point coordinate position can be taken as a reference point along the direction opposite to the moving direction of the current point, then a target position which is a first set distance value away from the reference point is determined, and finally the coordinate corresponding to the target position can be taken as the current camera coordinate position of the virtual camera.

It is understood that, considering that the virtual camera follows the target point and the distance from the target point is short, the first set distance value tends to take a small value, wherein the small value can be selected from a set distance range that can be set according to the height range that the game character can possibly present under the lens of the virtual camera, and preferably, the set distance range can be set to [20cm, 100cm ].

S2023, determining the current direction to be calibrated and the current camera coordinate position as the current position information to be calibrated of the virtual camera.

In this step, the current camera moving direction and the current camera coordinate position can be directly used as the current position information to be calibrated, which the virtual camera should have following the target point change under the current frame.

The following S203 to S205 of this embodiment give specific operations of calibrating the current position information to be calibrated.

S203, extracting the current direction to be calibrated and the current camera coordinate position contained in the current position information to be calibrated.

In this embodiment, after the current position information to be calibrated is determined, the current direction to be calibrated and the current camera coordinate position included in the current position information to be calibrated are extracted through this step.

And S204, obtaining the corresponding current calibration direction after the current direction to be calibrated is clockwise rotated to a set angle value.

The reason that the foresight is shielded by the game role existing when the game scene is presented by directly adopting the current position information to be calibrated is analyzed, and the fact that the foresight is shielded by the game role can be found out, the current direction to be calibrated is directly equal to the current role moving direction of the game role when the current frame changes, if the virtual camera directly presents the game scene in the current direction to be calibrated, the situation that the game role is positioned right in front of the virtual camera can occur, meanwhile, the foresight is always controlled to be displayed at the center of the screen in the shooting game, and when the game role is also presented right in front of the virtual camera, the foresight is shielded by the game role from the visual angle of a player user.

Based on this, the present embodiment considers adjusting the current direction to be calibrated of the virtual camera, so that the orientation of the virtual camera and the orientation of the game character are in different directions, thereby avoiding the game character being located right in front of the virtual camera. Thus, the current direction to be calibrated can be adjusted clockwise by this step, thereby obtaining a current calibration direction deviating from the current direction to be calibrated by a set angle value, wherein the set angle value can be selected to be 5 °.

S205, determining the current camera moving direction of the virtual camera according to the current calibration direction.

The determined current calibration direction cannot be directly used as the current camera moving direction of the virtual camera, so that the game role and the sight bead can be completely separated and presented. Specifically, a camera calibration point may be determined by extending this step in the current calibration direction, and then the current camera movement direction of the virtual camera may be determined based on the aiming point and the current camera coordinate position of the virtual camera.

For example, fig. 2d is a flowchart for determining a moving direction of a virtual camera in a game scene presenting method according to a second embodiment of the present invention. As shown in fig. 2d, determining the current camera moving direction of the virtual camera according to the current calibration direction specifically includes the following operations:

and S2051, determining a camera calibration point which is a second set distance value away from the current camera coordinate position along the current calibration direction.

In this step, the camera calibration point to be formed may be considered as a second set distance value from the current camera coordinate position in the current calibration direction, where the second set distance value may specifically be understood as a distance value that can be expressed as infinity, and it may be known that when the distance value is greater than 1000, the distance value may be considered as infinity, so that the value of the second set distance value is not specifically limited in this embodiment, and may be a value greater than 1000, for example, this step may be preferably 10000.

S2052, determining a direction vector formed based on the current camera coordinate position and the camera calibration point as a current camera movement direction of the virtual camera.

In this step, after the current camera coordinate position and the camera calibration point are known, a direction vector can be formed in the current coordinate system based on the two coordinate points, and the direction vector can be used as the current camera moving direction of the virtual camera.

S206, determining the current camera moving direction and the current camera coordinate position as the current camera position information corresponding to the virtual camera after calibration.

And S207, controlling the virtual camera to change the previous pose corresponding to the previous camera position information to the current pose corresponding to the current camera position information.

In this embodiment, the previous camera position information may be specifically understood as camera position information that the virtual camera has when moving along with the game character in the previous frame, where the previous camera position information may be determined based on related operations in the game scene presenting method provided in this embodiment when the virtual camera is in the previous frame, and the previous camera position information may be directly acquired when the virtual camera is in the current frame.

In this embodiment, the game character changes in the current frame according to the current direction information input by the user, and the corresponding target point and the virtual camera also need to change to the determined position. The pose is specifically understood to be a state that combines information such as a direction and a coordinate position.

In this embodiment, it can be considered that the virtual camera can have the state of the previous pose in the previous frame through the previous camera position information (including the previous camera moving direction and the previous camera coordinate position), and in the current frame, the virtual camera needs to be controlled to change from the previous pose to the current pose corresponding to the current camera position information (the current camera moving direction and the current camera coordinate position).

It can be known that, while the pose state of the virtual camera is controlled to change by this step, the game character and the target point respectively change in pose by corresponding position information.

And S208, acquiring current rendering data corresponding to the virtual camera in the current pose.

In this embodiment, a game scene in a shooting game is rendered by a virtual camera, and when the virtual camera is in a current pose at a current frame, current rendering data corresponding to the virtual camera in the current pose needs to be acquired through this step.

S209, presenting the current game scene where the game role is located on the terminal screen through the current rendering data, and controlling a sight for shooting aiming to be displayed at the central point of the terminal screen.

After the current rendering data corresponding to the current frame of the virtual camera is obtained through the above S208, the current game scene where the game character is located can be presented on the terminal screen through the current rendering data. Meanwhile, the sight bead used for shooting aiming by the player user in the shooting game can be controlled to be displayed at the central point of the terminal screen, so that a visual effect that the game scene changes smoothly along with the change of the game role and the game role is displayed at the position on the left side of the sight bead is provided for the player user in the shooting game.

The method for presenting the game scene in the shooting game provided by the embodiment of the invention embodies the operation of determining the current position information to be calibrated of the virtual camera, also embodies the operation of calibrating the current position information to be calibrated to obtain the current camera position information of the virtual camera, and also embodies the operation of presenting the game scene through the current camera position information. According to the technical scheme, firstly, the position information of the virtual camera when the virtual camera changes along with the game role is determined through the additionally arranged target point for cushioning, so that the game scene picture is smoothly presented; meanwhile, the operation of calibrating the position information of the virtual camera determined based on the position information of the target point is added before the game scene is smoothly presented, and by adopting the position information of the virtual camera after calibration, the game scene can be smoothly presented when moving and changing along with the game role, the shielding of the game role on the sight bead at the center of the screen can be effectively avoided, the sight bead can be always presented in the visual field of the user, and therefore the effects of improving the shooting hit rate of the user and improving the game experience are achieved.
