The method flow according to the present application will be described below.
Referring to fig. 4, fig. 4 is a flowchart of a method for controlling a flight of a virtual aircraft according to an embodiment of the present application. The embodiment is exemplified by applying the method to a terminal, which may be the first terminal 120 shown in fig. 1, and the method includes:
401. when the terminal receives the creation instruction, the terminal creates the virtual aircraft.
The creation instruction is used for instructing the terminal to create the virtual aircraft. In some embodiments, the creation instruction may be triggered by a user operation. For example, the terminal may display a call control in the virtual scene, and when a user wants to call the virtual aircraft, the terminal may perform touch operation on the call control, and then receive a trigger signal to the call control, trigger a creation instruction, and create the virtual aircraft. The calling control is used for calling the virtual aircraft to enter the virtual scene, and the form of the calling control can be a button displayed in the virtual scene in a suspension mode.
402. The terminal displays the virtual aircraft in the virtual scene.
The terminal can obtain the initial position of the virtual aircraft from the virtual scene, and can display the virtual aircraft at the initial position, so that the display effect of the virtual aircraft entering the field is achieved, and the function of calling out the virtual aircraft by a user is achieved.
The starting position may be in the sky, the ground or the ocean of the virtual scene, and the embodiment does not limit the starting position. The starting location may also be referred to as a Take-Off and Landing spot (VTOL spot) or a departure location. In some embodiments, a position may be pre-selected in the virtual scene, configured as a starting position of the virtual vehicle, and the virtual vehicle may be displayed at the pre-configured starting position to achieve the effect that the virtual vehicle generates at a fixed location. In other embodiments, the terminal may randomly generate a position, use the position as a starting position of the virtual aircraft, and display the virtual aircraft at the randomly generated starting position, thereby achieving the effect that the system randomly selects the generation point of the virtual aircraft. Alternatively, the starting position may be located at a preset altitude in the sky of the virtual scene, thereby achieving the effect of the virtual aircraft being generated at a fixed altitude.
In the above step 401 and step 402, through the creation instruction, the virtual aircraft may also be obtained in a manner other than the above manner in the process of creating and displaying the virtual aircraft, for example, the virtual aircraft may be a virtual resource in a virtual scene, the terminal may display the virtual aircraft at a target position in the virtual scene, and the user may control a virtual object to drive the virtual aircraft, which manner is specifically adopted by the embodiment of the present application is not limited.
403. And when a flight instruction is received, the terminal controls the virtual aircraft to fly according to the flight instruction.
The terminal can display a flight control in a user graphical interface, and a user can perform touch operation on the flight control to trigger the terminal to receive a flight instruction so as to control the virtual aircraft to fly.
The flight command may include flight commands in multiple directions, such as forward, reverse, left, right, up, down, and the like. The terminal can control the virtual aircraft to fly towards the direction indicated by the flight instruction according to the flight instruction.
404. In the flight process, the terminal acquires the flight speed of the virtual aircraft in the virtual scene, and according to the difference of the flight speed, the terminal executes the following steps 405, 406 or 407.
In the flight process, the flying speed of this virtual aircraft is different, the power that this virtual aircraft received also can be different, for example, when the flying speed of this virtual aircraft is less, this virtual aircraft can only be influenced by power, when the flying speed of this virtual aircraft is slightly bigger, this virtual aircraft not only receives power influence, can also receive the influence of power, when the flying speed of this virtual aircraft is greater than a definite value, this virtual aircraft except power, resistance, can also receive a backswing power, this backswing power is used for controlling the pitch angle of this virtual aircraft and reduces. It is understood that the greater the pitch angle of the virtual vehicle, the greater the flight speed experienced by the virtual vehicle, i.e., the backswing force is opposite to the power direction of the virtual vehicle.
The steps 403 and 404 are processes of acquiring the flying speed of the virtual aircraft in the virtual scene, and the above description is only given by taking the acquiring the flying speed in the flying process as an example, and when the virtual aircraft initially flies, the terminal may also acquire the flying speed, but the flying speed is zero. Of course, in a possible implementation manner, when the flight speed of the virtual aircraft is zero, two situations may be included, in one situation, the virtual aircraft is located on the ground, and in another situation, the virtual aircraft may hover in the air, which is not limited in this embodiment of the present application.
405. And when the flying speed is greater than a first speed threshold value, the terminal acquires a target pitch angle of the virtual aircraft according to the power and resistance borne by the virtual aircraft and the backswing force opposite to the power direction.
Wherein the backswing force is used to control the pitch angle reduction of the virtual aircraft.
When the flying speed is higher, a backswing force can be applied to the virtual aircraft to control the flying speed of the virtual aircraft, so that the virtual aircraft gradually adjusts the pitch angle of the virtual aircraft and then adjusts the virtual aircraft to fly at a constant speed.
The pitch angle of the virtual aircraft may refer to an included angle between the virtual aircraft and a horizontal plane, that is, a forward tilt angle of the virtual aircraft. It will be appreciated that the greater the pitch angle of the virtual vehicle, the greater the airspeed of the virtual vehicle.
Specifically, the step 405 may be implemented by the following steps one to four:
step one, the terminal can obtain the power borne by the virtual aircraft according to the received flight instruction.
And when the user performs forward operation, the terminal can obtain the power borne by the virtual aircraft according to the flight instruction triggered by the forward operation. For example, as shown in fig. 5, the terminal controls the virtual aircraft to fly in a virtual scene, and the viewing direction of the virtual scene is the flying direction of the virtual aircraft. As shown in fig. 6, the direction of the power is the direction for controlling the front part of the virtual aircraft to turn from top to bottom, and according to the right-hand rule, the direction of the moment of the power is horizontal to the left. Where moment is the tendency of an object to rotate about a rotational axis or pivot by an applied force, in newton-meters.
And step two, the terminal can acquire the backswing force which is opposite to the power direction and is borne by the virtual aircraft.
The backswing force can be set by a related technician as required, and is not limited in the embodiment of the application. For example, the direction of the swinging back force is the direction for controlling the front part of the virtual aircraft to turn from bottom to top in fig. 6. According to the right hand rule, the torque direction of the power is horizontal to the right.
And step three, the terminal can obtain the resistance borne by the virtual aircraft according to the current pitch angle of the virtual aircraft, and the resistance is positively correlated with the current pitch angle of the virtual aircraft.
The moment of resistance is in a direction opposite to the forward roll direction of the virtual aircraft. In one possible implementation, the terminal may obtain a product of the current pitch angle and a target coefficient, and use the product as the resistance.
And step four, the terminal can obtain the target pitch angle of the virtual aircraft according to the power, the resistance and the backswing force.
After the terminal acquires each force, the change condition of the pitch angle of the virtual aircraft can be determined according to the resultant force of the plurality of forces, so that the target pitch angle is acquired.
In a possible implementation manner, in the fourth step, the terminal may obtain a target angular acceleration of the change of the pitch angle of the virtual aircraft according to the power, the resistance, and the backswing force, and then obtain a target angular velocity of the change of the pitch angle of the virtual aircraft according to the target angular acceleration, so as to obtain the target pitch angle of the virtual aircraft according to the target angular velocity.
When the terminal acquires the target angular acceleration, the target angular acceleration can be acquired according to the resultant force of the three forces. The three forces are each a vector having a magnitude and a direction, the target angular acceleration is also a vector having a magnitude and a direction, and the direction of the target angular acceleration includes the direction of the downward or upward roll of the front of the virtual vehicle.
Specifically, the terminal may obtain a resultant force of the power, the resistance force, and the backswing force, obtain a ratio of the resultant force to the moment of inertia, and use the ratio as a target angular acceleration of the change of the pitch angle of the virtual aircraft. After the target angular acceleration is obtained, the terminal can obtain the micro-integral of the target angular acceleration to obtain the target angular velocity. Similarly, the terminal obtains the calculus of the target angular velocity to obtain the target pitch angle.
406. And when the flying speed is smaller than a second speed threshold value, the terminal acquires a target pitch angle of the virtual aircraft according to the power borne by the virtual aircraft, wherein the second speed threshold value is smaller than the first speed threshold value.
The second speed threshold may be set by a person skilled in the art as needed, and is not limited in this embodiment of the application. In the embodiment of the application, when the flying speed is low, the resistance borne by the virtual aircraft can be ignored, so that the terminal can obtain the target pitch angle of the virtual aircraft according to the power borne by the virtual aircraft.
The acquisition source of the power may be the same as the content shown in step 405, and the process of acquiring the target pitch angle by the terminal according to the power may also be the same as the content shown in step 405, and the target angular acceleration may be acquired first, and then the angular velocity may be acquired, but the resistance and the backswing force are both zero.
407. And when the flying speed is greater than or equal to the second speed threshold and less than the first speed threshold, the terminal acquires a target pitch angle of the virtual aircraft according to the power and the resistance borne by the virtual aircraft.
When the flying speed is slightly larger, the resistance borne by the virtual aircraft needs to be considered, but the flying speed is not larger than the first speed threshold value, so that the backswing force does not need to be considered, and the terminal can obtain the target pitch angle according to the power and the resistance. The acquisition source of the power and the resistance may be the same as the content shown in the step 405, and the process of acquiring the target pitch angle by the terminal according to the power and the resistance may also be the same as the content shown in the step 405, and the target angular acceleration may be acquired first, and then the angular velocity may be acquired, but the backswing force is zero.
The step 406 and the step 407 are processes of obtaining the target pitch angle of the virtual aircraft according to the power borne by the virtual aircraft when the flying speed is less than or equal to the first speed threshold, and only a second speed threshold is set in the processes, and there is a possibility that: when the flying speed is less than or equal to the first speed threshold value, the terminal directly obtains the target pitch angle of the virtual aircraft according to the power borne by the virtual aircraft, and the virtual aircraft is not influenced by the resistance at the moment. The embodiments of the present application do not limit this.
408. And the terminal controls the virtual aircraft to fly according to the target pitch angle in the virtual scene.
Through any one of the above steps 405, 406 or 407, after the terminal acquires the target pitch angle, the virtual aircraft may be controlled to fly according to the target pitch angle. For example, as shown in fig. 7, in step 205, when the virtual vehicle is subjected to a backswing force, the pitch angle of the virtual vehicle is decreased, and the virtual scene is better displayed. As shown in fig. 8, when the virtual vehicle is not subjected to the backswing force, the pitch angle of the virtual vehicle is large, and the virtual vehicle tilts forward severely.
In a possible implementation manner, when the virtual aircraft is subjected to three forces, the three forces may balance the stress on the virtual aircraft, so that the pitch angle of the virtual aircraft does not change, and the flying speed can be stabilized. Specifically, when the resultant force of the power, the resistance and the backswing force opposite to the power direction borne by the virtual aircraft is zero, the terminal acquires a target pitch angle of the virtual aircraft, and in the virtual scene, the virtual aircraft is controlled to fly at a constant speed according to the target pitch angle.
The three conditions of 205, 206, 207 and 208 are analyzed, and the change of the pitch angle of the virtual aircraft is explained by the process that the flying speed of the virtual aircraft changes from small to large.
In a specific example, as shown in fig. 9, taking the virtual aircraft as a helicopter as an example, a user controls the helicopter to move forward, the terminal may control the helicopter to move forward, a horizontal leftward power moment M1(t) is applied to a nose of the helicopter, t is time, based on the power, the terminal may control a forward tilt angle of the helicopter to gradually increase, that is, a pitch angle to gradually increase, and when a flight speed of the helicopter reaches a certain value, a horizontal rightward backswing moment M2(t) is applied to the helicopter, and the terminal may control the forward tilt angle of the helicopter to gradually decrease, that is, the pitch angle to gradually decrease. The resistance is not shown in the above process, but the resistance may be calculated as a moment in the calculation. M1, M2, Mf, below, represent three forces, respectively, so that when the helicopter is three-force balanced, i.e., M1 is M2+ Mf, the terminal can control the forward tilt angle of the helicopter to remain constant and steady forward.
In one specific example, M1For the power moment received by the helicopter, M2For the horizontal backswing moment received by the helicopter, x is a second speed threshold, when the speed of the helicopter reaches x, the helicopter is subjected to resistance which is proportional to the current pitch angle theta, MfK θ. Where k is the target coefficient and is a positive number. v' is a first speed threshold.
For example, it takes t ' for the helicopter to reach v ', t < t ', i.e. the helicopter is not subjected to a backswing force when the speed of the helicopter is less than the first speed threshold. Angular acceleration of helicopter is alphatCan be obtained by the following formula one:
the formula I is as follows:
wherein,Iis the moment of inertia. ThetatIs the pitch angle at time t.
When t is t', the angular velocity ω of the helicoptert′Can be obtained by the following formula two:
the formula II is as follows:
the pitch angle of the helicopter can be obtained by the following formula three:
the formula III is as follows:
when t > t', the angular acceleration alpha of the helicoptertCan be obtained by the following formula four:
the formula four is as follows:
angular velocity omega of helicoptert′Can be obtained by the following formula five:
the formula five is as follows:
the pitch angle of the helicopter can be obtained by the following formula six:
formula six:
when M is1＝M2At + k θ ", the helicopter is balanced by three forces in the horizontal direction and flies with the forward tilt angle θ".
Wherein, ω is0At an initial angular velocity, θ0For initial pitch, if the helicopter is flying from rest, the initial angular velocity and initial pitch mayThe initial angular velocity and the initial pitch angle are 0, and of course, those skilled in the art may set the initial angular velocity and the initial pitch angle according to the requirement, which is not limited by the embodiment of the present application.
In one possible implementation, in addition to changing the pitch angle of the virtual vehicle through the above-described operations, the virtual vehicle may also be steered, which may be accomplished through a perspective turn of the virtual scene. Specifically, when a steering instruction is received, the terminal may acquire a target view angle rotation angle of the virtual scene according to the steering instruction. And the terminal displays the virtual scene which changes along with the rotation of the visual angle in the process of controlling the visual angle to rotate the target rotation angle.
In one possible implementation, in addition to changing the pitch angle of the virtual vehicle through the above-described operations, the virtual vehicle may ascend or descend, and the ascent and descent of the virtual vehicle may be achieved through an altitude change of the perspective of the virtual scene. Specifically, when a lifting instruction is received, the terminal may obtain a target height change value of a viewing angle of the virtual scene according to the lifting instruction, and the terminal displays the virtual scene that changes with a change of the viewing angle in a process of controlling the height of the viewing angle to change the target height change value.
In one possible embodiment, the method for controlling the flight of the virtual vehicle may also be applied to a blockchain system, and after the steps 405, 406, and 407, the terminal may send the flight speed, the received force, and the target pitch angle of the virtual vehicle as flight data of the virtual vehicle to the blockchain system, and the blockchain system stores the flight data to the blockchain.
Optionally, after receiving the flight data, the node device of the blockchain system may further perform the same steps as the above steps 405, 406, and 407, check the flight data to determine whether the flight data determined by the terminal is correct, and store the flight data onto the blockchain when the flight data passes the check.
The node device may generate a block based on the flight data, broadcast the block to other node devices, and add the block to the blockchain when the block passes through the consensus of the blockchain system.
