Detailed Description
The application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be noted that, for convenience of description, only the portions related to the present application are shown in the drawings.
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
Fig. 1 shows a flow 100 of a first embodiment of a game scene control method according to the application. The game scene control method comprises the following steps:
Step 101, starting a target game.
In this embodiment, a game application may be installed on a user's terminal. The user clicks on an icon of the game application, and the game application can be opened. The user clicks a start button of the target game in the game application, and the target game can be started. Wherein the target game is a game provided by a gaming application, typically a large FPS.
Step 102, detecting an operation of dragging the mouse on the screen in a first direction, and determining an in-screen track of the mouse based on the operation.
In this embodiment, the terminal may detect an operation of dragging the mouse in a first direction on the screen and determine an in-screen trajectory of the mouse based on the operation.
In general, a user may drag a mouse on a screen to move in a first direction, and a track of the movement of the mouse within the screen is an in-screen track of the mouse. The first direction may be any direction. For example, the first direction may be a left-side direction (right-side, upper left-side, lower left-side), or a right-side direction (right-side, upper right-side, lower right-side).
In practice, the coordinate points of the mouse are two-dimensional coordinate points under a preset coordinate system, and are defined as (x, y). Taking a preset coordinate system with an origin at the upper left corner of the screen, a right positive direction of a horizontal axis (x axis) and a downward positive direction of a vertical axis (y axis) as an example, when the mouse is at the upper left corner of the screen, the coordinates are (0, 0); when the mouse is in the lower right corner of the screen, its coordinates are (height). Where width is the width of the screen and height is the height of the screen.
In some optional implementations of this embodiment, the terminal may obtain coordinates of a point on the track of the mouse in the screen by:
First, a general motion listener is set.
And then, callback the peripheral information to the universal motion function through the universal motion monitor to obtain the motion event object.
Finally, resolving the coordinates of the points of the mouse on the track in the screen from the motion event object.
Specifically, call GLSurface class, set event snoop setOnGenericMotionListener. All peripheral messages (including but not limited to gamepads, mice, wheels, touch pads, etc.) are recalled into onGenericMotion (View, motionEvent motionEvent) functions by this callback to obtain a MotionEvent object from which the mouse coordinate points (x, y) are resolved.
Step 103, controlling the direction of the game scene of the target game based on the in-screen trajectory.
In the present embodiment, the terminal may control the direction of the game scene of the target game based on the in-screen trajectory.
In general, the direction of the game scene may be associated with the dragging direction of the mouse. The rotation angle of the game scene may be associated with the dragging distance of the mouse. For example, by dragging the mouse in a left direction, the game scene can be controlled to rotate counterclockwise 360 degrees, the rotation angle being positively correlated to the distance dragged in the left direction. Further, by dragging the mouse in a left direction, there may be a case where the mouse reaches the left boundary of the screen. For another example, by dragging the mouse in a right direction, the game scene can be controlled to rotate 360 degrees clockwise, the rotation angle being positively correlated with the distance dragged in the left direction. Further, by dragging the mouse in the right direction, there may be a case where the mouse reaches the right boundary of the screen.
It should be noted that, the terminal detects the drag operation of the mouse in real time, and controls the direction of the game scene in real time based on the operation. In addition, the terminal may also detect whether the mouse reaches the boundary of the screen. If the boundary of the screen is not reached, continuing to detect the dragging operation of the mouse; if the boundary of the screen is reached, detecting whether the mouse is continuously dragged in the first direction. If the mouse is not dragged continuously in the first direction, continuing to detect the dragging operation of the mouse; if the mouse continues to be dragged in the first direction, step 104 is performed.
Step 104, responding to the fact that the mouse continues to drag towards the first direction after reaching the boundary of the screen, and estimating the out-of-screen track of the mouse based on the in-screen track of the mouse.
In this embodiment, the terminal may estimate the out-of-screen track of the mouse based on the in-screen track of the mouse when the mouse continues to drag in the first direction after reaching the boundary of the screen. The end point of the track in the screen of the mouse is the start point of the track outside the screen of the mouse, the track outside the screen and the track inside the screen are in smooth transition, and the track trend is consistent.
Taking a preset coordinate system with an origin point at the left upper corner of the screen, a positive direction with a right horizontal axis (x axis) and a positive direction with a downward vertical axis (y axis) as an example, when the mouse reaches the left boundary of the screen, the abscissa x=0 of the coordinate point, and if the mouse continues to move leftwards, the abscissa x of the coordinate point is a negative number; when the mouse reaches the right boundary of the screen, the abscissa x=width of the coordinate point thereof, and if the mouse continues to move rightward, the abscissa x of the coordinate point thereof is a value greater than width. The ordinate y of the coordinate point of the mouse can be normally acquired.
In some optional implementations of this embodiment, the terminal may obtain coordinates of a point on the off-screen track of the mouse by:
First, coordinates (x 1, y 1) of a first point p1 and coordinates (x 2, y 2) of a second point p2 on an on-screen trajectory, and an ordinate y3 of a third point p3 on an off-screen trajectory are acquired.
In general, the time interval for the mouse to pass through the first point p1, the second point p2, and the third point p3 is less than a preset time interval. The preset time interval is short, that is, the mouse passes through the first point p1, the second point p2, and the third point p3 in a short time.
Then, the abscissa x3 of the third point p3 is calculated based on the coordinates (x 1, y 1) of the first point p1, the coordinates (x 2, y 2) of the second point p2, and the ordinate y3 of the third point p 3.
Step 105, continuing to control the direction of the game scene based on the off-screen trajectory.
In this embodiment, the terminal may continue to control the direction of the game scene based on the off-screen trajectory.
It should be noted that, the direction of controlling the game scene based on the off-screen track is consistent with the control mode of controlling the direction of the game scene based on the on-screen track, and will not be described here again.
In some alternative implementations of the present embodiment, the device performing the game scene control method is an android system, and the application programming interface level (API level) of the device is less than 29.
According to the game scene control method provided by the embodiment of the application, under the condition of starting the target game, the operation of dragging the mouse in the first direction on the screen is detected, the on-screen track of the mouse is determined based on the operation, and the direction of the game scene of the target game is controlled based on the on-screen track. Under the condition that the mouse continues to drag to the first direction after reaching the boundary of the screen, estimating the out-of-screen track of the mouse based on the in-screen track of the mouse, and continuing to control the direction of the game scene based on the out-of-screen track. The direction of the game scene can be controlled continuously after the mouse is dragged to the boundary of the screen, so that the game scene is ensured to rotate continuously, and the game experience of a user is improved.
With continued reference to FIG. 2, a flow 200 is shown that is a second embodiment of a game scene control method according to the present application. The game scene control method comprises the following steps:
Step 201, starting a target game.
Step 202, detecting an operation of dragging the mouse on the screen in a first direction, and determining an in-screen trajectory of the mouse based on the operation.
Step 203, controlling the direction of the game scene of the target game based on the in-screen trajectory.
In this embodiment, the specific operations of steps 201 to 203 are described in detail in steps 101 to 103 in the embodiment shown in fig. 1, and are not described herein.
In step 204, in response to the mouse continuing to drag in the first direction after reaching the boundary of the screen, coordinates (x 1, y 1) of the first point p1 and coordinates (x 2, y 2) of the second point p2 on the track inside the screen and an ordinate y3 of the third point p3 on the track outside the screen are acquired.
In this embodiment, in the case where the mouse continues to drag in the first direction after reaching the boundary of the screen, the terminal may acquire coordinates (x 1, y 1) of the first point p1 and coordinates (x 2, y 2) of the second point p2 on the in-screen trajectory, and an ordinate y3 of the third point p3 on the out-screen trajectory.
In general, the time interval for the mouse to pass through the first point p1, the second point p2, and the third point p3 is less than a preset time interval. The preset time interval is short, that is, the mouse passes through the first point p1, the second point p2, and the third point p3 in a short time.
It should be noted that, the method for acquiring the coordinates of the point on the track in the screen of the mouse and the ordinate of the point on the track in the screen of the mouse is described in detail in step 102 in the embodiment shown in fig. 1, and will not be described herein.
Step 205, if y 1-! =y2-! =y3, and an intersection point p5 with the x axis is obtained by making a perpendicular to the x axis from the first point p 1.
In this embodiment, if the mouse passes through the first point p1, the second point p2, and the third point p3 in a short time, it is possible to default that the first point p1, the second point p2, and the third point p3 are linear, and then the abscissa of the third point p3 can be calculated based on the coordinates (x 1, y 1) of the first point p1, the coordinates (x 2, y 2) of the second point p2, and the ordinate y3 of the third point p3 using a tangent formula.
For y 1-! =y2-! In the case of =y3, the first point p1, the second point p2, and the third point p3 are regarded as points on a straight line, and an x-axis perpendicular is drawn from the first point p1 to obtain an intersection point p5 with the x-axis.
In step 206, an extension line connecting the first point p1 to the second point p2 is obtained to obtain an intersection point p4 with the x-axis.
In this embodiment, an extension line connecting the first point p1 to the second point p2 can obtain an intersection point p4 with the x-axis. The triangle p1p4p5 having the first point p1, the intersection point p4, and the intersection point p5 as vertices is a right triangle.
