Problems solved by technology

However, the natural person turns at any angle, so high-fidelity simulation cannot be performed, and the scale is too large and the calculation accuracy is low, which can no longer meet the needs of users
[0004] 2. The trigonometric function method has high precision and good fidelity, but the control effect is poor, the calculation time is too long and it is easy to cause system crashes and other problems
Since the computing power of touch-screen mobile devices is far from comparable to that of PCs, this solution is rarely used in practical applications.
[0005] 3. On the touch-screen mobile terminal, the control mode of the 3D virtual character cannot be carried out by using the traditional keyboard and mouse control method, and a new control mode must be adopted to solve the control problem of the virtual character. Commonly there are two kinds of virtual button and gesture control; Among them, the virtual button is a virtual object in the form of a button fixed at the front of the virtual scene
Simply use gesture control, the same as the subspace method, the character's steering range is limited

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the drawings and embodiments.

[0032] This embodiment provides a method for solving the motion conflict between a 3D virtual character on a touch screen terminal and a scene camera, which includes the following steps:

[0033] Step S1: Perform displacement calculation: Combine virtual buttons and gestures to control the virtual character. The displacement offset in the sensing area at any time can be converted by screen coordinates, and vice versa; that is, the algorithm can be calculated according to the offset Get the coordinates of the virtual character in the world coordinate system at any time;

[0034] Step S2: Perform orientation calculation: In the horizontal direction of the virtual character, the position of the scene camera always keeps a fixed distance from the virtual character's z-axis coordinates, and moves with the virtual character. The direction control always keeps the same distance a...

Abstract

The invention relates to a solution for a conflict between a 3D virtual character of a touch screen terminal and movement of a scene vidicon. The solution specifically comprises the steps as follows: 1, the movement direction of the virtual character is the direction of a gesture acquired in real time with respect to a virtual button coordinate system; 2, the position of the scene vidicon always stills at a fixed distance to a Z-axis coordinate of the virtual character, and moves along with the virtual character, and the direction of the scene vidicon always keeps equal distance and same direction with the virtual character, or keeps facing a screen; and 3, movements of the scene vidicon and the virtual character can be computed in a same progress, computation is divided into four kinds of computation according to different gestures in a horizontal direction, and the vertical computation is separately computed according to a gravity rule. According to the method provided by the invention, the virtual button is combined with the gesture, computation of a trigonometric function is avoided, and the problem of the conflict between the character and viewing angle control is solved by horizontal coordinate conversion of the screen.

Description

Technical field [0001] The invention relates to the field of virtual games, in particular to a method for solving the motion conflict between a touch screen terminal 3D virtual character and a scene camera. Background technique [0002] There are three types of virtual character control: posture control, motion control, and perspective (also called viewpoint) control. The perspective control is to solve the problem of consistency between the perspective of the character and the virtual scene. In practical applications, this problem is a common and difficult problem. And the emergence of touch-screen mobile terminals makes the traditional keyboard and mouse control methods no longer applicable. It is necessary to re-research an operation set that can adapt to the new situation in order to control the virtual characters. There are two existing viewing angle control technologies: one is to divide the world coordinates into subspaces of the same size, and each subspace uses differe...
