Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. 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 application.
For ease of understanding, an application scenario to which the embodiment of the present application is applied is described below with reference to fig. 1.
Fig. 1A is a schematic view of an application scenario provided in an embodiment of the present application. Referring to fig. 1A, a terminal apparatus 101 and a game server 102 are included. The terminal device 101 may be a mobile phone, a tablet, a notebook computer, or a desktop computer, and the terminal device 101 may interact with a user through a graphical user interface. The terminal device 101 can establish a communication connection with the game server 102 through a wireless network, so that game data in the game running process can be interacted between the terminal device 101 and the game server 102. For example, the terminal device 101 may return operation behavior data of the user of the terminal device 101 to the game server, and may acquire a game screen or the like from the game server.
The game running on the terminal device 101 is configured with at least one game scene, each game scene can be provided with a plurality of virtual cameras, the virtual cameras can be used for virtually shooting different visual angles of the game scene to obtain a game picture, one virtual camera corresponds to one shooting visual angle, and a plurality of game pictures can be shot under one shooting visual angle. The virtual camera is not displayed in the graphical user interface, which displays the game picture taken by the virtual camera. The switching of the game screen may be realized by switching the virtual camera.
Next, the relationship between the virtual camera and the game screen will be described with reference to fig. 1B.
Fig. 1B is a schematic view of a game screen provided in the embodiment of the present application. Please refer to fig. 1B, which includes an interface a, an interface B, and an interface C.
Referring to the interface a, the terminal device displays a game screen 1, the game screen 1 corresponds to the virtual camera 1, that is, the game screen 1 is obtained by virtually shooting a game scene through the virtual camera 1, and the game screen 1 is displayed in the graphical user interface.
Referring to the interface B, after the user inputs a control operation (e.g., switching a person scale, loading a carrier, etc.), the virtual camera 1 is switched to the virtual camera 2, the virtual camera 2 virtually shoots a game scene to obtain a game screen 2, and the game screen 2 is displayed in the graphical user interface.
Referring to the interface C, after the user inputs a control operation (e.g., switching a person name, loading a carrier, etc.), the virtual camera 2 is switched to the virtual camera 3, the virtual camera 3 virtually shoots a game scene to obtain a game screen 3, and the game screen 3 is displayed in the graphical user interface.
In the related art, when switching the virtual camera, the target virtual camera is first stored in the cache, and the priority of the virtual camera in the cache is modified, so that the priority of the target virtual camera is the highest, thereby realizing switching of the virtual camera.
The above switching method has at least the following technical problems:
1. the priority of the virtual camera in the cache needs to be modified every time the virtual camera is switched, so that the switching process is time-consuming, the switching time of the game picture is too long, and the switching speed is low.
2. Each time the switched virtual camera is stored in the cache, the number of the virtual cameras in the cache is too large, the consumption of the cache is large, and the management of the virtual cameras in the cache is not facilitated.
In the implementation of the method, after the target virtual camera to be switched is determined to be obtained, the current virtual camera is directly switched to the target virtual camera. The priority of the virtual camera does not need to be modified, and the speed of game picture switching is improved. In addition, only the resident virtual camera and the current virtual camera are stored in the cache, the resident virtual camera is a virtual camera corresponding to a preset game picture with high display frequency, the number of the virtual cameras stored in the cache is reduced, the consumption of the cache is reduced, and the virtual cameras in the cache are convenient to manage.
The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may exist independently or may be combined with each other, and details of the same or similar concepts or processes are not repeated in different embodiments.
Fig. 2 is a first flowchart of a game screen processing method provided by the present application. Referring to fig. 2, a user can operate on a graphical user interface through an input device such as a touch screen or a mouse, and a terminal device obtains the graphical user interface by executing a game application and rendering the game application on a display of the terminal device, and the method for switching game screens includes:
s201, responding to the control operation, and determining a virtual camera operation instruction according to the shooting visual angle of the game picture currently displayed by the terminal equipment.
A main camera and a plurality of virtual cameras can be arranged in a game scene, the main camera can be used for showing game pictures, and the virtual cameras can be used for defining parameters such as shooting positions and shooting angles of the main camera. The essence of displaying the game picture through the virtual camera is that the main camera virtually shoots the game scene through shooting parameters defined by the virtual camera and displays the shot game picture.
The game picture refers to a picture obtained by shooting by a virtual camera under a certain angle of view, and one virtual camera can obtain a plurality of game pictures. For example, the virtual camera 1 is a virtual camera following the angle of view, which can capture a plurality of game frames, and each game frame captured at the angle of view corresponds to the virtual camera 1 as long as the capturing angle of view is not changed.
The graphical user interface may include a control, and the control may be a control that controls the game object to switch the shooting angle of view, for example, the control may be a driving control (which may correspond to a vehicle angle of view), a shooting control (which may correspond to a third person angle of view), and an NPC dialog control (which may correspond to an NPC angle of view). During the game, the user can input control operation on the graphical user interface through the control. The control operation may be an operation of switching a shooting angle of view, for example, the control operation may switch the first person angle of view to the third person angle of view, or switch the person angle of view to the carrier angle of view.
The photographing perspective may be a perspective at which the virtual camera photographs at a fixed position with respect to the game object. For example, the follow-up photographing view angle may be a position in which the virtual camera photographs at 30cm behind the game object, and the relative position of the virtual camera and the game object does not change regardless of movement of the game object.
The virtual camera operation command is a switch-in target virtual camera command or a switch-out current virtual camera command. And the target virtual camera switching-in instruction is used for instructing to switch in the target virtual camera, namely, the target virtual camera is determined to be obtained according to the shooting visual angle of the currently displayed game picture, and the current virtual camera is switched to the target virtual camera. The current virtual camera switching-out instruction is used for instructing switching out from the current virtual camera, namely, switching out from the current virtual camera if the target virtual camera is not determined according to the shooting visual angle of the currently displayed game picture.
The virtual camera comprises a resident virtual camera and a temporary virtual camera, the resident virtual camera is a virtual camera corresponding to a preset game picture, and the resident virtual camera can be a virtual camera corresponding to a game picture with higher display frequency. For example, the resident virtual camera may be a virtual camera reflecting the following view angle, or may be a virtual camera reflecting the view angle of a vehicle such as a vehicle, a ship, or an airplane. The temporary virtual camera refers to a virtual camera other than the resident virtual camera, e.g., the temporary virtual camera may be a virtual camera in a game scene that reflects the perspective of a certain NPC.
S202, determining a target virtual camera according to the virtual camera operation instruction and the virtual camera stored in the cache.
The virtual cameras stored in the cache include a resident virtual camera and a current virtual camera. The resident virtual camera may be a virtual camera corresponding to a preset game screen, and the current virtual camera may be a virtual camera corresponding to a currently displayed game screen. The resident virtual camera stored in the cache may be a virtual camera corresponding to a game screen that has been displayed by the terminal device.
During the course of an actual game, the virtual camera stored in the cache may change. For example, when a game screen is switched every time, if the current virtual camera is a resident virtual camera and the resident virtual camera is not included in the cache, the resident virtual camera is saved in the cache; and if the current virtual camera is the temporary virtual camera, deleting the temporary virtual camera in the cache after the switching process is finished.
For ease of understanding, the virtual camera in the cache is described below in conjunction with fig. 3.
Fig. 3 is a schematic diagram of a virtual camera in a cache according to an embodiment of the present disclosure. Referring to fig. 3, at time t1, the resident virtual cameras stored in the cache include the resident virtual camera 1, the resident virtual camera 2, and the resident virtual camera 3, and the current virtual camera stored in the cache is the resident virtual camera 4.
At time t2, assuming that the current virtual camera needs to be switched to temporary virtual camera 1, the resident virtual camera 4 may be stored to the resident virtual camera queue and temporary virtual camera 1 may be stored to the cache.
At time t3, assuming that the current virtual camera needs to be switched to the resident virtual camera 5, the temporary virtual camera 1 is deleted in the cache, and the resident virtual camera 5 is stored in the cache.
When the types of the virtual camera operation instructions are different, the mode of determining the target virtual camera is different, including the following two cases:
case 1, the virtual camera operation command is a cut-in target virtual camera command.
In this case, the target virtual camera may be determined by: judging whether a target virtual camera exists in the cache, if so, determining the virtual camera with the same shooting parameters as the target virtual camera in the cache as the target virtual camera; if not, generating the target virtual camera.
For example, assuming that the target camera is the resident virtual camera 5, it may be determined that the resident virtual camera 5 exists in the cache, and if the resident virtual camera 5 exists in the cache, the resident virtual camera 5 existing in the cache is determined as the target virtual camera; if the resident virtual camera 5 does not exist in the cache, the resident virtual camera 5 is generated, and the generated resident virtual camera 5 is determined as the target virtual camera.
Case 2, the virtual camera operation instruction is a cut-out current virtual camera instruction.
In this case, the target virtual camera may be determined by: judging whether a resident virtual camera exists in the cache, if so, determining the resident virtual camera used last time in the cache as a target virtual camera; if not, the switching is finished, the original machine position is kept, and the current game picture is displayed.
And S203, displaying a target game picture corresponding to the target virtual camera in the graphical user interface.
When the target game screen is displayed, the switching to the target game screen may be instantaneous or smooth.
In the embodiment shown in fig. 2, a virtual camera operation instruction is determined according to a game picture currently displayed by the terminal device and a control operation input by a user; the terminal equipment can determine the target virtual camera through the virtual camera operation instruction and the virtual camera stored in the cache, and display a target game picture corresponding to the target virtual camera in the graphical user interface. In the above process, after the target virtual camera to be switched is determined, the current virtual camera is directly switched to the target virtual camera. The priority of the virtual camera does not need to be modified, and the speed of game picture switching is improved.
In the embodiment shown in fig. 2, when the types of virtual camera operation instructions (the switch-in target virtual camera instruction or the switch-out current virtual camera instruction) are different, the processing methods of the game screens are also different. Next, a game screen processing method corresponding to an instruction to enter a target virtual camera is described by the embodiment shown in fig. 4 to 6, and a game screen processing method corresponding to an instruction to exit a current virtual camera is described by the embodiment shown in fig. 7.
Fig. 4 is a second flowchart of a game screen processing method according to an embodiment of the present application. In the embodiment shown in fig. 4, the virtual camera operation instruction is a cut-in target virtual camera instruction. Referring to fig. 4, the method for switching the game screen may include:
s401, responding to the control operation, and determining a virtual camera operation instruction according to the shooting visual angle of the game picture currently displayed by the terminal equipment.
The virtual camera operation instructions may be determined by: determining at least one cut-in mode corresponding to a shooting visual angle of a currently displayed game picture, and if the at least one cut-in mode comprises a target cut-in mode corresponding to control operation, determining that a virtual camera operation instruction is a target virtual camera cut-in instruction; and if the target cut-in mode is not included in at least one cut-in mode, determining that the virtual camera operation instruction is a current virtual camera cut-out instruction.
For example, for a scene in which a game object interacts with a non-player character (NPC), two virtual camera operation instructions are included, which are specifically as follows:
in case 1, before the game object interacts with the NPC, the shooting angle of view corresponding to the game screen displayed on the graphical user interface may be a first-person angle of view, at least one cut-in mode corresponding to the first-person angle of view may be set in advance, and the cut-in mode may be a cut-in mode corresponding to the NPC dialog control operation, a cut-in mode corresponding to the shooting control operation, or the like. When a game object is ready to interact with the NPC, the NPC dialogue control operation is input by a user, and the virtual camera operation instruction is determined to be a cut-in target virtual camera instruction due to the fact that the preset cut-in mode comprises a cut-in mode corresponding to the NPC dialogue operation. After the target virtual camera is cut in, the game object is interacting with the NPC, and the shooting visual angle corresponding to the game picture displayed on the graphical user interface is the NPC visual angle.
And 2, when the game object and the NPC are interacted, the user inputs and switches the shooting visual angle control operation, and because a cut-in mode corresponding to the NPC visual angle is not set in advance, the virtual camera operation instruction can be determined as a current virtual camera cut-in instruction, namely, after the game object and the NPC are interacted, the NPC visual angle corresponding to the interactive game picture is quitted.
S402, if the virtual camera operation instruction is a target virtual camera switching-in instruction, whether a target virtual camera exists in the cache or not is judged.
It should be noted that the execution process of S402 may refer to the execution process of S202, and is not described herein again.
If yes, go to S403.
If not, go to S404.
And S403, determining the virtual camera which is the same as the camera parameter of the target virtual camera in the cache as the target virtual camera.
The camera parameters may include the type of components the camera owns and initialization parameters for the respective components. The component type may be an INPUT component, a BODY component, a COLLIDER component, and the like. The initialization parameter of the INPUT assembly may be a rotation angle of the camera; the BODY component may be a planned shooting position of the camera; the collision component may be the actual camera position.
S404, camera parameters of the target virtual camera are obtained, the virtual camera is created according to the camera parameters, and the target virtual camera is generated.
S405, determining a picture switching mode.
The picture switching mode is an instantaneous switching mode or a smooth switching mode.
And S406, updating the camera states of the current virtual camera and the target virtual camera according to the picture switching mode.
The camera states include an active state and an inactive state.
When the picture switching modes are different, the process of updating the camera states of the current virtual camera and the target virtual camera is also different, including the following two cases:
in case 1, the screen switching mode is the instantaneous switching mode.
