There may be differences for the degree of concern of quasi- object.It, can also be according to the default of virtual role in this example embodiment based on this
Attribute configures the weights of all kinds of virtual objects.
For example, the virtual role of output type occupation may be needed to pay close attention to object of attack emphatically, and for teammate's
Concern may be relatively small.That is, the weight of object of attack is greater than the power of companion for the virtual role of output type occupation
Weight.In addition, the degree of concern of the virtual role of output type occupation may be different, for example, elite for different objects of attack
The weight of the object of attack (that is, causing virtual role compared with the object of attack of major injury) of class may be larger, and common attack
The weight of object (that is, object of attack that smaller injury is caused to virtual role) may be smaller.In addition, some pure output type occupations
Virtual role may not pay close attention to companion, in this case, the weight of companion is zero.With the virtual role of output type occupation
On the contrary, may need to pay close attention to emphatically companion's information (e.g., blood volume, magic amount etc.) for the virtual role of therapeutic type occupation, this
When, the weight of companion is greater than the weight of object of attack.For example, table 1 is to be configured according to the preset attribute of virtual role respectively
One example of the weight of class virtual objects, but the present disclosure is not limited thereto.
Table 1
| Occupation | Teammate | Monster a | The strange b of elite | Monster ... |
| A (without paying close attention to the occupation of teammate) | 0 | 1 | 5 | …… |
| B | 1 | 1 | 5 | …… |
| C | 1 | 1 | 5 | …… |
| D (occupation for paying close attention to teammate) | 5 | 1 | 5 | …… |
As shown in table 1, professional A is pure output type occupation, and for the virtual role of professional A, teammate's weight is 0, strange
The weight of object a is 1, and the weight of the strange b of elite is 5.Professional D be emphasis pay close attention to teammate occupation, for professional D virtual role and
Speech, teammate's weight are 5, and the weight of monster a is 1, and the weight of the strange b of elite is 5.
Pass through the weight configuration mode in this example embodiment, on the one hand, can represent in digital form virtual
Role is conducive to calculation processing to the degree of concern of all kinds of virtual objects；On the other hand, for different types of virtual role,
Different weights is cooked up, can satisfy experience of the user to different types of virtual role.
S2. it is counted according to the weight of the virtual objects in the view directions of virtual role and the virtual role visual field
The information content of the virtual objects in the virtual role visual field is calculated, and with the virtual objects in the virtual role visual field
The sum of information content be up to target to calculate visual angle and adjust the angle.
With reference to shown in Fig. 2, in this illustrative embodiment, the step S2 may include:
S21. using the current location of the virtual role as pole, using the current visual angle direction of the virtual role as polar axis
Establish polar coordinate system.In this example embodiment in such a way that polar coordinates are handled, has to facilitate and establish coordinate, equation letter
List and it is easy to the advantages that calculating.But in other exemplary embodiments of the disclosure, other coordinate systems can also be used, such as
Eulerian coordinate system carries out Modeling Calculation, therefore the present disclosure is not limited thereto.
S22. the polar angle and institute according to each virtual objects in the virtual role visual field in the polar coordinate system
The weight of virtual objects is stated to calculate the information content of the virtual objects, and the apsi message of the virtual objects is shown as ρi
cosθi.Wherein, ρiAnd θiThe weight of i-th virtual objects and in the pole in the respectively described virtual role visual field
Polar angle in coordinate system.In this case, the information content of the virtual objects may, for example, be information content or the teammate of monster
Information content.In addition, in this illustrative embodiment, in addition to using the form of cosine, can also use other three
Angle function type, however, the present disclosure is not limited thereto, it alternatively, can be using other mathematical way in addition to trigonometric function
To indicate the information content of the virtual objects.
With reference to Fig. 3, wherein O point is the current location of virtual role, and the direction OX is the current visual angle direction of virtual role.
Using O point as pole, polar coordinate system is established by polar axis of OX, it can be seen that θ1For pole of the teammate M in the polar coordinate system
Angle, if the weight of teammate M is ρ1, then the information content of teammate M is ρ1cosθ1.Similarly it can be concluded that the information content of monster a is ρ2cos
θ2, the information content of the strange b of elite is ρ3cosθ3。
S23. the information content of virtual objects in the virtual role visual field is added, obtains Σ ρ i cos θi。
S24. the visual angle is calculated using the method for trigonometric function extreme value to adjust the angle.
Assuming that it is α that the visual angle, which adjusts the angle, in the method for the trigonometric function extreme value, target is to make the virtual angle
The information content of all virtual objects is maximum in color visual field, and in this case, information content maximum formula becomes Pα=Σ ρi(cosθi
+ α), formula expansion can be obtained:
Pα=Σ ρi(cosθi+α)
=Σ ρi(cosθi cosα-sinθi sinα)
=Σ ρi cosθi cosα-Σρi sinθi sinα
=cos α × Σ ρi cosθi-sinα×Σρi sinθi
=((Σ ρi cosθi)2+(Σρisinθi)2)1/2×sin(α+Φ)
Wherein sin Φ=Σ ρi cosθi/((Σρi cosθi)2+(Σρi sinθi)2)1/2
That is Φ=arcsin (Σ ρi cosθi/((Σρi cosθi)2+(Σρi sinθi)2)1/2)
Since as sin (α+Φ)=1, PαMaximum, so there is+Φ=90 ° α
α is adjusted the angle to acquire the visual angle, it may be assumed that
α=90 °-arcsin (Σ ρi cosθi/((Σρi cosθi)2+(Σρi sinθi)2)1/2)
The range of α are as follows: 180 ° >=α >=-180 °.When α is positive value, can indicate counterclockwise to be adjusted visual angle, and
When α is negative value, can indicate clockwise to be adjusted visual angle.
With reference to Fig. 4, in the another exemplary embodiment of the disclosure, after step s 22, the step S2 can be with
Include:
S25. the information of the virtual objects in the virtual role visual field under multiple default view directions is calculated separately
The sum of amount.
The multiple default view directions can be certain angular interval (for example, 2 °, 5 °, 10 ° etc.) and the visual angle of acquisition
Direction, but not limited to this, the multiple default view directions can also be the view directions taken with specific rule, this is exemplary
Particular determination is not done in embodiment to this.
S26. it counts corresponding default when the sum of information content of the virtual objects is maximum in the virtual role visual field
View directions, and calculate the visual angle according to the default view directions and adjust the angle.
In the illustrative embodiments of the disclosure, the method that visual angle adjusts the angle that calculates is given, however, the disclosure is not
It is limited to this, the visual angle can be adjusted the angle by other means and calculated.
S3. it is adjusted the angle according to the visual angle to adjust the view directions of the virtual role.
Be calculated visual angle adjust the angle after, can be applied by rotatable game in virtual camera angle coverage
The view directions of adjustment virtual role are adjusted the angle according to obtained visual angle.Further, since relative to virtual role, virtual objects
Position change in real time, therefore visual angle calculated adjust the angle also can real-time change, when visual angle adjust the angle it is smaller when,
The phenomenon that continually adjustment may be such that virtual role shakes.In order to solve the problems, such as shake, it is pre- that one can be preset
If angle, when visual angle calculated, which adjusts the angle, is less than the predetermined angle, view directions will not be adjusted, it is ensured that trip
The stationarity at play visual angle.May be used also that is, being adjusted the angle according to the visual angle to adjust the view directions of the virtual role
To include: to judge that the visual angle adjusts the angle whether to be greater than or equal to predetermined angle；At the visual angle, adjustment angle is greater than or waits
In the case where the predetermined angle, adjusted the angle according to the visual angle to adjust the view directions of the virtual role.In addition,
Above-mentioned predetermined angle can be have been set in game application development process, can also by user's sets itself predetermined angle,
Particular determination is not done in this illustrative embodiment to this.
In some game applications, if adjusting visual angle during virtual role is mobile, user will form
The double effect that position displacement adds visual angle to rotate, may bring certain sense of discomfort to user.And it is carried out in virtual role pre-
If virtual role may not move during movement, then adjustment view directions can only generate a rotating effect at this moment, avoid
User's dizziness.Therefore, in this illustrative embodiments, in order to further ensure that the stationarity and suitable object for appreciation property of game application, In
Before the view directions for adjusting the virtual role, it can also judge whether the virtual role is carrying out deliberate action, for example,
The deliberate action can be release technical ability or it is general attack, but not limited to this.Therefore, it is adjusted the angle according to the visual angle to adjust
The view directions for stating virtual role can also include: to judge whether the virtual role is carrying out deliberate action；Described in judgement
Virtual role is adjusted the angle according to the visual angle in the case where carrying out the deliberate action to adjust the view of the virtual role

In addition, the virtual role view directions control method further includes adjusting view directions with rotational angular velocity k, turn
Dynamic angular speed k indicates the angle of visual angle adjustment per second.If the time for carrying out a deliberate action is t, once preset
Movement, the angle of visual angle adjustment are t × k.For example, predetermined angle is 10 °, then if it is 20 ° that calculated visual angle, which adjusts the angle,
Meet the condition of visual angle adjustment.When virtual role carries out general attack, if it is 500ms and set for carrying out the primary general time attacked
Rotational angular velocity be 10 °/s, then it is primary it is general attack after, the angle of visual angle adjustment is 5 °, therefore, carry out four times it is general attack after,
Visual angle adjustment process terminates.
