本文主要是介绍引入线程的贪吃蛇风骚走位，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1.在main函数中分别引入线程t1 和线程 t2
一个线程用来刷新界面，一个线程用来改变方向
2.刷新界面函数，无限次刷新
3. 也是无限循环while(1) 定义key 从键盘获取输入方向，赋值给dir;
4.在初始化函数中确定蛇向有行走为方向
5.从改变方向的函数changeDir()函数中获取dir的方向，在增加节点函数addNode()中，用switch函数实现蛇方向的改变
代码演示：
#include <curses.h>
#include <stdlib.h>
#include <unistd.h>
#include <pthread.h>#define UP 1
#define DOWN 2
#define LEFT 3
#define RIGHT 4void initNcurses()
{initscr();keypad(stdscr,1);noecho();
}struct Snake
{int hang;int lie;struct Snake *next;};struct Snake *head = NULL;
struct Snake *tail = NULL;
int key;
int dir;int hasSnakeNode(int i,int j){ // da yin she shen tistruct Snake *p;p = head; //ding tou while(p != NULL){if(p -> hang == i && p ->lie == j){return 1;} p = p ->next;}return 0;
}void gamePic()
{int hang;int lie;move(0,0);for(hang = 0;hang<20;hang++){if(hang==0){for(lie=0;lie<20;lie++){printw("--");}printw("\n");}if(hang>= 0 || hang <=18){for(lie = 0;lie<=20;lie++){if(lie == 0 || lie == 20){printw("|");}else if(hasSnakeNode(hang,lie)){printw("[]");}else{printw(" ");}}printw("\n");}if(hang == 19){for(lie=0;lie<20;lie++){printw("--");}printw("\n");printw("by caoshupei,key= %d\n",key);}}
}void addNode()
{struct Snake *new = (struct Snake *)malloc(sizeof(struct Snake));new -> next =NULL;switch(dir){case UP:new -> hang = tail -> hang-1;new -> lie = tail -> lie;break;case DOWN:new -> hang = tail -> hang+1;new -> lie = tail ->lie;break;case LEFT:new -> hang = tail -> hang;new ->lie = tail -> lie-1;break;case RIGHT:new -> hang = tail -> hang;new -> lie = tail -> lie+1;break;}tail -> next = new;tail = new;
}void deleteNode()
{struct Snake *p;p = head;head = head ->next;free(p); // fang zhi zao cheng hen duo kong yu de jie dian
}void initSnakebody()
{struct Snake *p;dir = RIGHT;//di yi ci yun xing shi bu hui zouwhile(head != NULL) //yi kai shi deng yu kong{ //zhuang qiao la jiu shi bu wei kong p = head;head = head -> next;free(p); //shi fang nei cun}head = (struct Snake*)malloc(sizeof(struct Snake));head -> hang = 1; // gu ding chu shi weizhi head -> lie = 1;head -> next = NULL; // tou de xie yi ge wei kongtail = head; // wei ba bian cheng touaddNode(); // zeng jia jie dianaddNode();addNode();
}void moveSnake()
{struct Snake *p;
struct Snake *new;addNode();deleteNode();if(tail -> hang == 0|| tail ->lie == 0|| tail->hang == 20 ||tail->lie ==20){initSnakebody();}
}void *refreshjiemian()
{while(1){moveSnake();gamePic();refresh();usleep(100000);}
}void *changeDir()
{while(1){key = getch();switch(key){case KEY_DOWN:dir = DOWN;break;case KEY_UP:dir = UP;break;case KEY_LEFT:dir = LEFT;break;case KEY_RIGHT:dir = RIGHT;break;}}
}int main()
{pthread_t t1;pthread_t t2;initNcurses();initSnakebody();gamePic();pthread_create(&t1,NULL,refreshjiemian,NULL);sleep(1);pthread_create(&t2,NULL,changeDir,NULL);while(1);getch();endwin();return 0;
}
