That is, these functional entities may be implemented in the form of software, or in one or more software-hardened modules, or in different networks and/or processor devices and/or microcontroller devices.
The exemplary embodiment first discloses a free viewing angle direction switching method, which is applied to a touch terminal capable of presenting an interactive interface, where the interactive interface may include a touch operation area. The touch terminal may be, for example, various electronic devices having a touch screen, such as a mobile phone, a tablet computer, a notebook computer, a game machine, and a PDA. The touch terminal can control a touch screen of the touch terminal to present an interactive interface, a virtual object, a touch operation area, a virtual battle scene, a virtual natural environment and the like through an application program interface of the touch terminal. The free view angle means that when the orientation of the free view angle is changed, the orientation and the moving direction of the virtual object are not changed, namely, the connection between the orientation of the free view angle and the orientation and the moving direction of the virtual object is cut off. Referring to fig. 1, the free viewing angle orientation switching method may include the steps of:
step S110, responding to an input initial event acting on the touch operation area, and acquiring the position of the input initial event in the touch operation area;
step S120, acquiring the target orientation of the free visual angle on a target plane vertical to the interactive interface according to the position of the input starting event in the touch operation area;
and step S130, controlling the free view angle to be directly switched to the target orientation from the orientation before the input starting event occurs.
Through the free visual angle direction switching method in the exemplary embodiment, on one hand, after the target direction is obtained, the free visual angle is controlled to be directly (i.e. immediately) switched to the target direction from the direction before the input starting event occurs, and compared with the related art, the process of continuously adjusting the current direction to the target direction is not performed, so that the operation steps are simplified, the efficiency of switching the direction of the free visual angle is improved, the operation cost is reduced, the instantaneity of switching the free visual angle is better, and meanwhile, the requirement of a user on the instantaneity of switching the free visual angle in a tense and fast-paced shooting game is met. On the other hand, the target orientation of the free visual angle on the target plane perpendicular to the interactive interface is obtained through the position of the input starting event in the touch operation area, so that a user can quickly determine the position of the input starting event in the touch operation area according to the relation between the orientation of the free visual angle and the position of the input starting event in the touch operation area, and the input starting event is executed in the touch operation area, the operation steps are simple and easy to learn, and the user experience is good.
Next, each step in the free viewing angle orientation switching method in the present exemplary embodiment will be further described.
In step S110, in response to an input start event acting on the touch operation area, a position of the input start event in the touch operation area is obtained.
In this exemplary embodiment, the touch operation area may be a virtual joystick area, a virtual cross control, or an area set by a developer for switching the orientation of a free viewing angle, which is not particularly limited in this exemplary embodiment. The shape of the touch operation area may be a circle, an ellipse, or a square, which is not particularly limited in this exemplary embodiment. The display state of the touch operation area may include: always displaying the touch control terminal in an interactive interface (namely a resident area in the interactive interface); and when the touch operation area is in a trigger state, the touch operation area is displayed in the interactive interface. It should be noted that the display state of the touch operation area is not limited to this. The input start event may be any one of a slide operation, a press operation, a drag operation, and the like.
The user can execute an input initial event in the touch operation area through a finger, a touch pen, and the like, for example, when the touch operation area is a virtual rocker area and the input initial event is a sliding operation, the user can slide in the virtual rocker area through the finger to execute a sliding operation acting on the virtual rocker area, and during the sliding process, the position of the virtual rocker in the virtual rocker area changes according to the change of the position of a touch point of the finger in the virtual rocker area. For another example, when the touch operation is a virtual joystick area and the input start event is a press operation, the user can press the virtual joystick area with a finger to perform the press operation on the virtual joystick area.
After an input initial event acting on the touch operation area is detected, the position of the input initial event in the touch operation area is acquired through a position acquisition module in response to the input initial event acting on the touch operation area. The position of the input start event in the touch operation area refers to a position of the end point of the touch point of the input start event in the touch operation area. For example, when the input start event is a sliding operation, the position of the input start event in the touch operation area is the position of the end point position of the touch point of the sliding operation in the touch operation area.
In step S120, according to the position of the input start event in the touch operation area, a target orientation of the free view angle on a target plane perpendicular to the interactive interface is obtained.
In this exemplary embodiment, the object plane perpendicular to the interactive interface may be parallel to an edge of the interactive interface, or may be not parallel to the edge of the interactive interface.
The method for acquiring the target orientation of the free view angle on the target plane perpendicular to the interactive interface according to the position of the input starting event in the touch operation area may include the following three ways.
As shown in fig. 2, the first method may include step S210 and step S220. Wherein:
in step S210, a direction of the input start event in the touch operation area is obtained according to a position of the input start event in the touch operation area.
In this exemplary embodiment, after acquiring the position of the input start event in the touch operation area, the process of acquiring the direction of the input start event in the touch operation area may include: as shown in fig. 3, a rectangular coordinate system is set in the touch operation area, and the direction of the input start event in the touch operation area is determined according to the direction from the position of the midpoint O of the rectangular coordinate system to the end position of the touch point of the input start event, and in fig. 3, the direction of the input start event in the touch operation area is in the first quadrant region of the rectangular coordinate system and forms an angle of 45 degrees with the positive X-axis. As shown in fig. 4, a rectangular coordinate system is set in the touch operation area, and the position of the input start event in the touch operation area is determined according to the direction from the position of the end point O of the rectangular coordinate system to the end point position of the touch point of the input start event, and in fig. 4, the direction of the input start event in the touch operation area is in the fourth quadrant area of the rectangular coordinate system and forms an angle of 60 degrees with the positive X-axis.
In step S220, a target orientation of the free viewing angle on a target plane perpendicular to the interactive interface is determined according to a direction of the input start event in the touch operation area. And the direction of the input starting event in the touch operation area corresponds to the orientation of the free visual angle on the target plane one by one.
In the present exemplary embodiment, a one-to-one correspondence relationship between the direction of the input start event in the touch operation area and the orientation of the free viewing angle on the target plane may be established, that is, the one-to-one correspondence between the direction and 360 degrees of the orientation is realized. For example, a rectangular coordinate system may be established in the target plane with the position of the free viewing angle as a midpoint, and a one-to-one correspondence relationship between directions at different angles to the forward X-axis in the touch operation area and directions at different angles to the forward X-axis in the target plane, respectively, e.g., a correspondence relationship between a direction at an angle of 45 degrees to the forward X-axis in the touch operation area and a direction at an angle of 45 degrees to the forward X-axis in the target plane. It should be noted that the manner of establishing the one-to-one correspondence between the direction of the input start event in the touch operation area and the orientation of the free viewing angle on the target plane in the present exemplary embodiment is not limited to this. On the basis, the direction of the free visual angle corresponding to the direction in the touch operation area is acquired through inputting the direction of the starting event in the touch operation area, and the direction is determined as the target direction.
In the second mode, the touch operation area may include eight touch operation sub-areas, and the eight touch operation sub-areas correspond to the eight directions of the free viewing angle on the target plane one by one. In the present exemplary embodiment, the touch operation area may be divided into eight touch operation sub-areas with the same area, and may also be divided into eight touch operation sub-areas with different areas, which is not particularly limited in the present exemplary embodiment. As shown in fig. 5, the process of dividing eight touch operation sub-areas is described by taking the touch operation area as a virtual joystick area. Firstly, a touch operation area is divided into 8 touch operation sub-areas with equal areas through 4 lines passing through the middle point of a virtual rocker area, wherein the included angles between two adjacent lines passing through the middle point are equal. As shown in fig. 5, the eight touch operation sub-areas are a first touch operation sub-area 501, a second touch operation sub-area 502, a third touch operation sub-area 503, a fourth touch operation sub-area 504, a fifth touch operation sub-area 505, a sixth touch operation sub-area 506, a seventh touch operation sub-area 507 and an eighth touch operation sub-area 508. A one-to-one correspondence relationship between the touch operation sub-areas and eight directions (for example, a forward direction, a backward direction, a leftward direction, a rightward direction, a forward left direction, a forward right direction, a backward left direction, and a backward right direction) of the free angle of view on the target plane is respectively established, for example, the first touch operation sub-area 501 corresponds to the forward direction, the second touch operation sub-area 502 corresponds to the forward left direction, the third touch operation sub-area 503 corresponds to the leftward direction, the fourth touch operation sub-area 504 corresponds to the backward left direction, the fifth touch operation sub-area 505 corresponds to the backward direction, the sixth touch operation sub-area 506 corresponds to the backward right direction, the seventh touch operation sub-area 507 corresponds to the rightward direction, and the eighth touch operation sub-area 508 corresponds to the forward right direction. Further, in order to more intuitively display the corresponding orientation of each touch operation sub-area, an identifier for indicating the corresponding orientation may be displayed in the touch operation sub-area, where the identifier may be a triangle or an arrow, and this is not particularly limited in this exemplary embodiment.
Based on this, as shown in fig. 6, the second method may include step S610 and step S620, where:
in step S610, the touch operation sub-area to which the input start event belongs is obtained according to the position of the input start event in the touch operation area. In the exemplary embodiment, the touch operation sub-area to which the input start event belongs may be determined according to the end position of the touch point of the input start event.
In step S620, an orientation corresponding to the touch operation sub-area to which the input start event belongs is determined as a target orientation.
In a third mode, as shown in fig. 7, the touch operation area is a virtual cross control, the virtual cross control includes four direction controls, and the four direction controls correspond to four directions of the free view on the target plane one by one. For example, the first direction control 701 corresponds to a forward facing orientation, the second direction control 702 corresponds to a leftward facing orientation, the third direction control 703 corresponds to a rearward facing orientation, and the fourth direction control 704 corresponds to a rightward facing orientation.
Based on this, as described in fig. 8, the third method may include step S810 and step S820, where:
in step S810, the direction control to which the input start event belongs is obtained according to the position of the input start event in the virtual cross control.
In step S820, the orientation corresponding to the direction control to which the input start event belongs is determined as a target orientation.
Among the three methods described above, the first method and the second method are more suitable for users who are familiar with the game because of no particular clear operation directivity, and the third method is more suitable for novice users because of clear operation and direction orientation.
In summary, the target orientation of the free viewing angle on the target plane perpendicular to the interactive interface is obtained by the position of the input start event in the touch operation area, so that the user can quickly determine the position of the input start event in the touch operation area according to the relationship between the orientation of the free viewing angle and the position of the input start event in the touch operation area, and execute the input start event in the touch operation area, and the operation steps are simple and easy to learn, and the user experience is better.
In step S130, the free viewing angle is controlled to be directly switched from the orientation before the input start event occurs to the target orientation.
In the present exemplary embodiment, after the target orientation is acquired, the free viewing angle is controlled to be switched from the orientation before the input start event occurs to the target orientation directly (i.e., immediately). While in the related art, the process of switching to the target orientation is to continuously adjust the free viewing angle from the orientation before the sliding operation to the target orientation through the trajectory of the sliding operation, that is, the orientation of the free viewing angle changes along with the change of the trajectory of the sliding operation, obviously, in the present exemplary embodiment, the free viewing angle is controlled to be directly (i.e., immediately) switched to the target orientation, and there is no process of continuously adjusting from the current orientation to the target orientation, so, in the present exemplary embodiment, the target orientation of the free viewing angle can be determined only according to the position of the input start event in the touch operation area, and the free viewing angle is directly controlled to be switched from the orientation before the input start event to the target orientation, thereby simplifying the operation steps, greatly reducing the time for switching the free viewing angle, improving the efficiency of switching the orientation of the free viewing angle, reducing the operation cost, and having good instantaneity, meanwhile, the requirement of the user on the instantaneity of switching the free visual angle in the tense and fast-paced shooting game is met.
Further, the method may further include: switching the free-viewing angle from the target orientation directly to an orientation before the input start event occurs in response to an input end event that is continuous with the input start event. In this exemplary embodiment, the input end event may be, for example, an operation of a finger leaving an interface of the touch operation area, and may also be an operation of a finger moving out of the touch operation area, which is not particularly limited in this exemplary embodiment. Upon receiving an input end event that is continuous with the input start event, the free-form viewing angle is switched directly (i.e., immediately) from the target orientation to the orientation before the input start event occurs in response to the input end event.
In the process of switching the orientation of the free viewing angle, the orientation of the free viewing angle changes, but the position of the free viewing angle does not change.
Therefore, the free visual angle can be rapidly switched from the direction before the initial event is input to the target direction through the initial event input, the free visual angle can be rapidly recovered from the target direction to the direction before the initial event is input according to the end event input, the operation is simple and easy to learn, the switching efficiency of the direction of the free visual angle is high, and the game experience and the operation hand feeling are well optimized in the compact shooting game battle.
In order to enlarge or reduce the free viewing angle field of view or change the free viewing angle reference point, the method may further include: and adjusting the position of the free visual angle on the target plane, and adjusting the visual field range of the free visual angle. In the present exemplary embodiment, with one virtual object in the field of view of the free view as a base point, enlarging the distance between the position of the free view and the position of the virtual object can expand the field of view of the free view when the position of the virtual object is not changed; the distance between the position of the free visual angle and the position of the virtual object is reduced, so that the visual field range can be reduced; the reference point of the free view angle may be changed by changing only the position of the free view angle without changing the distance between the position of the free view angle and the position of the virtual object. For example, as shown in fig. 9, the region between the two broken lines is the field of view of the free view, and when the free view 1 moves from a distance from the virtual object X1 to a distance from the virtual object X2, it can be visually seen in the figure that the field of view of the free view becomes larger.
It should be noted that the position of the free view angle is the position of the virtual camera in the interactive interface, and the orientation of the free view angle is the orientation of the virtual camera.
In order to adjust the height of the field of view of the free viewing angle, the method may further include: and adjusting the position of the free visual angle in the direction vertical to the target plane, and adjusting the visual field height of the free visual angle. In the present exemplary embodiment, the height of the field of view of the free view angle can be changed by changing only the position of the free view angle in the direction perpendicular to the target plane without changing the position of the free view angle on the target plane.
