Embodiment Construction

[0014] In role-playing games, a virtual joystick is needed to advance and retreat game characters.

[0015] When the finger moves, according to the new coordinates of the touch point given by the operating system, combined with the last coordinate position of the finger, the movement trajectory is calculated, and the virtual joystick on the screen is moved according to the calculated movement trajectory to ensure that the virtual joystick is always near the fingers.

[0016] After the virtual joystick moves, the logical center point of the virtual joystick needs to be reset. If the distance between the coordinates of the finger on the touch screen and the new logical center point of the virtual joystick is still greater than the distance limit, continue to move according to the above rules virtual joystick.

[0017] When the distance between the center point of the virtual joystick and the coordinates of the touch screen of the finger is less than the distance limit gate, sto...

Abstract

The invention relates to a construction method for an electronic screen virtual rocker. The initial position of an operating button is determined through acquiring operation on a touch screen of a multi-touch terminal of a user, then the position of the operating button is controlled according to the movement direction of the operation to enable a touch point to be always located within the control range of the operating button, therefore, through achieving a scheme that the operating button moves along with the operating position on the multi-touch screen, the accuracy of the operation is improved, and operating deficiencies are avoided. The user is supported to perform more accurate man-machine interaction, the movement operation process is smoother, and misoperation is reduced.

Description

technical field [0001] The invention relates to a method for constructing a virtual rocker on an electronic screen. Background technique [0002] The virtual joystick refers to the joystick function realized by sliding the screen with fingers, which is more common in fighting games and FPS games. [0003] At present, the common virtual joystick chassis is a fixed area. When the finger shakes too much on the electronic screen, it will exceed the fixed area of ​​the chassis and exceed the sensing range of the device, resulting in difficult or missing operation, resulting in poor operating experience. Contents of the invention [0004] To address the shortcomings of the above-mentioned prior art, the virtual rocker of the present invention does not use a fixed area, and the rocker chassis can follow the movement of the rocker. During the specific operation, the finger touch point moves to a certain position on the electronic screen, and the virtual joystick will follow that ...
