Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

At present, in the existing movement control method of the virtual object, a unit of a game (namely, the virtual object) cannot move according to a track supposed by a player, and a track jitter phenomenon may occur, wherein the jittered track is not smooth, and the efficiency of unit movement is low. In order to draw a smooth unit movement track, the movement control method, the movement control device and the terminal device of the virtual object provided by the embodiment of the invention can be applied to terminal devices which can realize human-computer interaction, such as a client, a computer, a mobile phone, a tablet personal computer and the like, and are particularly suitable for a mobile phone RTS game scene.

To facilitate understanding of the present embodiment, a detailed description will be given of a method for controlling movement of a virtual object disclosed in the present embodiment.

The embodiment provides a method for controlling movement of a virtual object. The terminal device in this embodiment may be a mobile phone, a computer, a tablet computer, or other devices that can interact with a user. And displaying a game scene interface in the terminal equipment, wherein the game scene interface is used for interacting with a user, and executing the movement control method of the virtual object provided by the embodiment.

Referring to fig. 1, a schematic diagram of a game scene interface is shown, and as shown in fig. 1, circles in fig. 1 represent virtual objects, and a player can control the virtual objects to move in the game scene interface. There are 7 virtual objects in the game scene interface in fig. 1, and a player may draw a movement trajectory for the virtual object through the movement control method for the virtual object provided in this embodiment, so that any virtual object in fig. 1 moves to any position of the game scene interface in fig. 1 according to the movement trajectory. Based on the above description, referring to the flowchart of a method for controlling the movement of a virtual object shown in fig. 2, the method for controlling the movement of a virtual object includes the following steps:

in step S202, in response to the virtual object selection operation for the virtual object, the virtual object corresponding to the virtual object selection operation is determined as the target virtual object.

At least one virtual object is included in the game scene interface, and the player can select one or more virtual objects from the virtual objects as target virtual objects through a virtual object selection operation. The target virtual object refers to a virtual object which needs to move in the game scene interface. The virtual object selection operation may specifically be a click operation, a long-time press operation, or a circle-drawing operation. For example: as shown in FIG. 1, there are 7 virtual objects in the game scene interface, and a player can click or long-press one of the virtual objects to serve as a target virtual object. The player can also draw circles in the game scene interface, and all virtual objects in the circles can be used as target virtual objects.

In step S204, an initial trajectory of the target virtual object is determined in response to the trajectory drawing operation for the target virtual object.

After determining the target virtual object, the player may perform a trajectory drawing operation in the game scene interface to draw an initial trajectory for the target virtual object. The target virtual object may move along an initial trajectory. However, there is a high possibility of track jitter in the drawing of the initial track, which results in the initial track not being smooth, and if the target virtual object moves along the unsmooth initial track, the target virtual object may move with low efficiency, so that the initial track may be smoothed.

For example, if the terminal device is a mobile phone and the application scene is a mobile phone game, the player may perform a track drawing operation on the mobile phone screen with a finger to draw an initial track. Since the finger is thick, the initial track drawn is not fine, and the track jitter phenomenon is easy to occur.

For another example, if the terminal device is a computer and the application scene is a computer game, the player may perform a trajectory drawing operation with a mouse to draw an initial trajectory. The player may also experience a track shake while dragging the mouse, and the initial track drawn is not smooth.

And step S206, smoothing the initial track to obtain an optimized track of the target virtual object.

In order to eliminate track jitter, the initial track may be smoothed by a specific smoothing method including bezier curve smoothing, moving average smoothing, Savitzky-Golay filtering (S-G filtering), Spline curve smoothing, and the like, and one or more of the smoothing methods may be used to smooth the initial track; further, other smoothing methods than the above-described smoothing method may be employed. The trajectory obtained by smoothing the initial trajectory of the target virtual object is referred to as an optimized trajectory, and may be understood as a trajectory obtained by optimizing (smoothing) the initial trajectory.

And step S208, controlling the target virtual object to move along the optimized track.

The optimized track is subjected to smoothing processing, so that the influence of track jitter can be eliminated. Therefore, after the terminal device obtains the optimized track, the target virtual object can be controlled to move along the optimized track in the game scene interface.

According to the movement control method of the virtual object provided by the embodiment of the invention, the terminal equipment responds to the track drawing operation to determine the initial track of the target virtual object, carries out smoothing processing on the initial track to obtain the optimized track, and controls the target virtual object to move along the optimized track; the optimized track is smooth and can eliminate track jitter, and the target virtual object can move according to the track assumed by the player, so that the method has high moving efficiency.

The present embodiment provides another method for controlling movement of a virtual object, which is implemented on the basis of the foregoing embodiments; the embodiment focuses on a specific implementation of drawing an initial trajectory. As shown in fig. 3, another flow chart of the method for controlling the movement of the virtual object in the present embodiment includes the following steps:

step S302, in response to the virtual object selection operation for the virtual object, determines the virtual object corresponding to the virtual object selection operation as the target virtual object.

When the player selects the target, the player can select the target virtual object by clicking, long pressing, circling and other operations; besides, the terminal device can intelligently recommend some virtual objects as target virtual objects to be modified or confirmed by the player. For example, assuming that the game scene interface includes the virtual objects 1 to 5, the terminal device may recommend the virtual objects 1 to 3 as target virtual objects, and display the recommendation result to the player in the game scene interface in the form of message notification. If the player agrees to the recommendation result, directly confirming; if the player does not unify the recommendation results, the player may not confirm or modify, and if the player wants to modify, the player may modify on the basis of the recommendation results, such as modifying the virtual objects 1-3 into the virtual objects 1, 2, 4.

In addition, the player can also perform a virtual object selection operation by inputting an instruction. For example: the player can input and confirm the instructions for the virtual objects 1, 2, and 4 as the target virtual objects in the instruction input box of the game scene interface. After receiving the instruction, the terminal device may use the virtual objects 1, 2, and 4 as target virtual objects.

And step S304, responding to the long press operation or the dragging operation aiming at the target virtual object, and entering a track drawing mode of a game scene interface.

When the player performs the track drawing operation, the player can perform long-time pressing operation or dragging operation on the target virtual object to enter a track drawing mode of the game scene interface. For example, the player may enter the trajectory drawing mode for the target virtual object a by pressing the target virtual object a for 0.3 seconds. For another example, the player may slide the target virtual object B to enter a trajectory drawing mode of the target virtual object B.

In addition, the player may enter the trajectory drawing mode by inputting an instruction. For example: the player inputs an instruction to enter the trajectory drawing mode for the target virtual object C, and the terminal device can enter the trajectory drawing mode for the target virtual object C according to the instruction.

Besides the above modes, the terminal device may also preset other modes to enter the trajectory drawing mode, and the terminal device may enter the trajectory drawing mode as long as the user performs an operation according with the setting.

Step S306, receiving a trajectory drawing operation in the trajectory drawing mode, and taking a trajectory drawn by the trajectory drawing operation as an initial trajectory of the target virtual object.

After the terminal device enters the trajectory drawing mode, the player may draw an initial trajectory of the target virtual object in the trajectory drawing mode. Different terminal devices can have different initial track drawing modes. If the terminal equipment is a computer, the player can draw the track through a mouse; if the terminal equipment is a mobile terminal such as a mobile phone, a tablet personal computer and the like, a player can perform track drawing operation through fingers; besides, the player can also perform track drawing operation through some external devices connected with the terminal device, such as a stylus, a rocker, a handle and the like.

For the case that the terminal device is a mobile terminal such as a mobile phone or a tablet computer, and the player performs the track drawing operation by using a finger, the player may perform the track drawing operation by using an operation of sliding the finger, for example: in the track drawing mode, in response to a finger sliding operation for the touch terminal, a sliding track of the sliding operation is determined as an initial track of the target virtual object.

If the terminal device is a touch terminal capable of performing touch operation, a player can slide a finger on a game scene interface displayed by the touch terminal to perform the sliding operation, and a sliding track obtained by the sliding operation is used as an initial track of the target virtual object. In this mode, the player can perform a slide operation, and draw the initial trajectory quickly and accurately by using the slide trajectory obtained by the slide operation as the initial trajectory.

Referring to fig. 4, which is a schematic diagram of a sliding track drawing method, fig. 4 includes a game scene interface, and a character avatar on the left side in the game scene interface represents a target virtual object, which may also be referred to as a soldier card. The sliding track obtained by the user performing the finger sliding operation is curve 1 in fig. 4. As can be seen from fig. 4, the sliding trajectory (curve 1) is not smooth, and a smoothing process is required.

When a player slides a finger on the game scene interface, the game scene interface may not be able to completely display the game scene, and at this time, the touch terminal may drag the game scene interface and load the game scenes other than the game scene interface into the game scene interface. For the situation that the game scene interface cannot completely display the game scene, the game scene interface can be dragged through steps a 1-a 2:

step A1, responding to the finger sliding operation aiming at the touch terminal, and displaying the sliding track in the game scene interface.

The player can perform finger sliding operation on the touch terminal, wherein the player can perform finger sliding operation on a game scene interface of the touch terminal, and can also perform finger sliding operation on other areas except the game scene interface on the touch terminal. The sliding track obtained by the finger sliding operation of the player can be displayed in the game scene interface.

For example, assume that the touch terminal is a mobile phone, and a main screen of the mobile phone displays a game scene interface. The player may perform a finger sliding operation on the game scene interface displayed on the main screen and display a sliding trajectory obtained by the finger sliding operation on the game scene interface of the main screen.

For another example, assume that the touch terminal is a game machine, the game machine includes a main screen and a sub-screen, and the main screen displays a game scene interface. The player may perform a finger sliding operation on the game scene interface displayed on the main screen, or may perform a finger sliding operation on the sub-screen. Whether the player performs finger sliding operation on the main screen or the sub-screen, the obtained sliding track can be displayed in the game scene interface of the main screen.

Step A2, if the distance between the sliding track and the edge of the game scene interface is smaller than the preset distance threshold, the game scene interface is updated to load the game scene beyond the edge to the display area of the touch terminal.

In the process of displaying the sliding track on the game scene interface of the touch device, the sliding track may be too long to be displayed on the screen of one touch device. In this case, the terminal device may adjust the proportion and the content of the game scene interface displayed on the screen of the touch device, that is, update the game scene interface, so that the sliding track is displayed in the game scene interface of the touch device.

If the distance between the sliding track and the edge of the game scene interface is smaller than the preset distance threshold, it indicates that the sliding track has reached the edge of the game scene interface or is very close to the edge of the game scene interface, and at this time, the touch device may update the game scene interface, and load the game scene beyond the edge to the display area of the touch terminal, so that the touch terminal displays more game scenes.

For example, if the touch terminal is a mobile phone and the game scene is large, the display screen of the mobile phone may only display a part of the game scene (referred to as an a area), and if the distance between the sliding track and the edge of the a area is smaller than a preset distance threshold when the player performs the finger sliding operation, it indicates that the sliding track is already very close to the edge of the a area, and at this time, more game scenes (referred to as a B area) may be displayed on the display screen in a manner of zooming or dragging the game, that is, the B area is loaded to the display area of the mobile phone.

According to the method provided by the embodiment of the invention, the game scene interface is updated when the sliding track approaches the edge of the game scene interface, so that the game scene beyond the edge is loaded to the display area of the touch terminal. More game scenes can be displayed in the touch terminal, so that the player can conveniently perform finger sliding operation and draw a sliding track in the game scenes except the edge of the game scene interface.

And step S308, smoothing the initial track to obtain an optimized track of the target virtual object.

The sliding track obtained in the above steps is obtained by the sliding operation of the finger, so that the situation of track jitter is likely to occur, and the smoothing processing needs to be performed, and common smoothing processing modes include bezier curve smoothing, moving average smoothing, Savitzky-Golay filtering, Spline curve smoothing and the like.

The moving average smoothing means that data points in a neighborhood are averaged to replace a central point value of the neighborhood, and the moving average smoothing also comprises weighted moving average and exponential moving average besides general moving average. Savitzky-Golay filtering is a filtering method based on local polynomial least squares fitting. The Spline curve smoothing may be performed according to a plurality of Spline curve parametric equations. Specifically, the smoothing process may be performed by step B1-step B2:

and step B1, marking track punctuation points in the initial track at intervals of a preset first length from the starting point of the initial track.

Referring to fig. 5, which is a schematic diagram of a smoothing method, fig. 5 performs smoothing on the basis of the initial trajectory (curve 1) obtained in fig. 4. First, track punctuation, which is a dot (e.g., dots numbered 2 and 3) having a larger area in the initial track (curve 1), may be marked in the initial track every predetermined first length from the starting point of the initial track (i.e., the position of the soldier cards). For example, assuming that the first length is 10, one marker dot may be set every length 10 from the start.

It can be seen that the position of the first length from the soldier card in fig. 5 is the 1 st track punctuation (i.e. the dot labeled with the reference number 2), and the initial track (curve 1) in fig. 5 has 7 track punctuations, wherein the dot labeled with the reference number 3 is the 5 th track punctuation.

Step B2, smoothing the initial trajectory based on the trajectory mark in the initial trajectory to obtain the optimized trajectory of the target virtual object.

After the track punctuation of the initial track is marked, the initial track can be smoothed based on the track punctuation. For example, the smoothing process may be performed by means of a bezier curve in steps C1-C2.

And step C1, connecting adjacent track punctuations in the initial track to obtain a logic auxiliary line.

As shown in fig. 5, the locus punctuation, the start point and the end point in fig. 5 may be connected in order to obtain a logical auxiliary line (i.e., a dotted line in fig. 5). The terminal device may perform bezier curve smoothing with the help of the logical auxiliary line.

In step C2, bezier curve smoothing is performed on the logic auxiliary line.

The logic auxiliary line between every two adjacent track punctuations is a straight line, while the track between every two adjacent track punctuations in the initial track is an irregular curve. The track distance between every two adjacent track punctuations can be shortened by the logical auxiliary line. However, the logical auxiliary line is not smoothed, so the optimized trajectory can be obtained by performing bezier curve smoothing through the steps D1 to D5.

And D1, determining the target track punctuation based on the included angle between the adjacent line segments in the logic auxiliary line.

As shown in the figure, the intersection points of adjacent line segments in the logical auxiliary line are all locus punctuation. The angles between different adjacent segments are also different. The target track punctuation refers to the track punctuation which needs to be smoothed. Generally, all the track punctuations can be taken as target track punctuations to be smoothed, and track punctuations corresponding to included angles meeting a specific threshold range can be taken as target track punctuations to be smoothed.

And D2, determining a first anchor point and a second anchor point of the target track punctuation on the first logic auxiliary line and the second logic auxiliary line corresponding to the target track punctuation.

Taking the 5 th track punctuation (i.e. the dot of the reference numeral 3) in fig. 5 as an example, the reference numeral 4, which takes the 5 th track punctuation as the end point, is called a first logic auxiliary line, the reference numeral 5, which takes the 5 th track punctuation as the start point, is called a second logic auxiliary line, and the anchor points are the small circles with smaller areas before and after each track punctuation in fig. 5 (the anchor point of the reference numeral 6 on the first logic auxiliary line is called a first anchor point, and the anchor point of the reference numeral 7 on the second logic auxiliary line is called a second anchor point).

It can be seen that the distance between one track punctuation point and the anchor point of each anchor point corresponding to the track punctuation point is the same, and the distances between anchor points of different track punctuations are different, and the first anchor point and the second anchor point can be obtained through steps E1-E3:

and E1, determining the anchor point distance corresponding to the target track punctuations based on the included angle between the first logic auxiliary line and the second logic auxiliary line.

In this embodiment, an included angle between the first logic auxiliary line and the second logic auxiliary line is inversely proportional to the anchor point distance, and the anchor point distance may be enlarged or reduced in equal proportion according to the angle of the included angle. That is, the larger the included angle, the smaller the distance. If the included angle is 180 degrees, the anchor point distance is 0, the first logic auxiliary line and the second logic auxiliary line are a straight line, and the first anchor point, the target track punctuation and the second anchor point are mutually overlapped. The specific proportional relationship may be manually set by a player or a game designer, which is not limited herein.

Step E2, determine a point on the first logical auxiliary line that is a distance from the target trajectory punctuation point to be the first anchor point.

After determining the anchor point distance, a point on the first logical auxiliary line that is a distance from the target trajectory punctuation point by the anchor point distance may be determined as the first anchor point. For example, if the coordinates of the target track punctuations are (0, 0), the anchor point distance is 1, and the first auxiliary logical line is the x-axis, the coordinates of the first anchor point are (-1, 0).

Step E3, determine the point on the second logical auxiliary line that is a distance from the target trajectory punctuation point to be the second anchor point.

After the anchor point distance is determined, a point on the second logical auxiliary line which is away from the target track punctuation point by the anchor point distance can be determined as a second anchor point. For example, if the coordinates of the target track punctuations are (0, 0), the anchor point distance is 1, and the first auxiliary logical line is the y-axis, the coordinates of the second anchor point are (0, 1).

Step D3, generating a bezier curve between the first anchor point and the second anchor point based on the first logical auxiliary line and the second logical auxiliary line.

After determining the coordinates of the first anchor point and the second anchor point, and the positions of the first logical auxiliary line and the second logical auxiliary line, a bezier curve between the first anchor point and the second anchor point may be generated.

Step D4, replacing the first and second logical auxiliary lines with a bezier curve between the first and second anchor points.

After the bezier curve is generated, the first and second logical auxiliary lines between the first and second anchor points may be replaced with the bezier curve, which may ensure that the replaced logical auxiliary lines are smooth. As shown in fig. 5, the first and second logical auxiliary lines between the first anchor point denoted by reference numeral 6 and the second anchor point denoted by reference numeral 7 are replaced with smooth curves (i.e., the curve 8 in fig. 5) in fig. 5, resulting in that the replaced logical auxiliary lines are smooth.

And D5, taking the replaced logic auxiliary line as the optimized track of the target virtual object.

The method provided by the embodiment of the invention explains the Bezier curve smoothing method in detail, the replaced logic auxiliary line is used as the optimized track of the target virtual object, and the obtained optimized track consists of a Bezier curve and a straight line and has higher smoothing degree.

After the optimized trajectory is obtained, the optimized trajectory may be displayed on a game scene interface. By displaying the optimized trajectory, it is clear that the player confirms the actual movement trajectory of the target virtual object, and the player can further modify or confirm the optimized trajectory.

In step S310, the control target virtual object moves along the optimized trajectory.

After the optimized track is obtained, the terminal device can control the target virtual object to move along the optimized track, the moving process is very smooth, track jitter does not exist, and the target virtual object has high moving efficiency.

A specific flow of the method for controlling movement of a virtual object according to this embodiment is illustrated. The player can click or long-press the virtual object to perform virtual object selection operation, and the selected virtual object is taken as a target virtual object. The player can draw an initial trajectory of the target virtual object through a finger sliding operation with respect to the target virtual object entering a trajectory drawing mode. The terminal equipment can perform smoothing processing after obtaining the initial track, specifically, firstly, marking track punctuations in the initial track, then drawing a logic auxiliary line between adjacent track punctuations, determining anchor point distances according to included angles between the logic auxiliary lines, determining two anchor points corresponding to the track punctuations, drawing a Bezier curve to replace the logic auxiliary lines, and completing the smoothing processing to obtain the optimized track. And finally, displaying the optimized track on the game scene interface, and controlling the target virtual object to move along the optimized track.

It should be noted that the above method embodiments are all described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.
