Image drawing method and device

Abstract

The invention discloses an image drawing method. The image drawing method comprises the following steps that when receiving a moving operating instruction, a terminal device acquires key point coordinates on a first current position locus of a target columnar object and the moving direction indicated by the moving operating instruction, wherein the target columnar object comprises a head component and a body component, the central section in the length direction of the body component comprises a plurality of circles and a plurality of squares, every two circles in the plurality of circles are connected in sequence through a point of tangency, two opposite sides of each of the plurality of squares sequentially penetrate through the centers of two adjacent circles according to the connection order of the circles, and the key point coordinates comprise the center coordinate of the head component and the coordinates of at least two circle centers in the plurality of circles; and the key point coordinates on the updated position locus are determined, so that the moved target columnar object is drawn. For the image drawing method provided by the embodiment of the invention, during moving detection, only part of the circle centers need to be detected, thus the number of the key points needing to be detected is reduced, the detection efficiency is improved, and meanwhile, the computation cost is also reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an image drawing method and device. Background technique [0002] With the development of Internet applications, there are more and more types of games, among which the Snake game is welcomed by the majority of users. The greedy snake is a snake raised by the player. The snake moves under the control of the player, and will continue to eat food (energy points) during the movement, so as to grow continuously. In the process of moving the snake to eat energy points, the player needs to control the movement of the snake to avoid colliding with other snakes. Once the head of a snake hits the body of another snake, the snake will die, and the dead snake will turn into energy points for other snakes to eat. [0003] The body of the snake in the current Snake game is composed of circular superposition, such as figure 1 As shown, this kind of method can simply describe the shape ...

AI Technical Summary

Problems solved by technology

[0003] The body of the snake in the current Snake game is composed of circular superposition, such as figure 1 As shown, this kind of method can simply describe the shape of the snake, but there is a large gap between the circle and the circle. It seems that the body of the snake will have a lot of sawtooth, especially when the snake turns, the sawtooth of the turning part will be more prominent

[0004] In the prior art, in addition to the problem of jaggedness in the drawing described in the above picture, there are many key points that need to be detected in the process of detecting the movement of the snake, not only to detect the center of each circle, but also to detect the overlapping of two circles. The points in the jagged part lead to low detection efficiency and increase the computational overhead
