Current progress:

How to move the package snake:

typedef struct SNAKEINFO{INT numparts;/* How many parts, snake body divided by how many segments */int lenparts[game_width];/* snake Body length of each paragraph */int xpartshead[ game_width];/* The x-coordinate of paragraph I of the body of the snake, the initial value is 1 */int the y-coordinate of paragraph I of the ypartshead[game_width];/* snake body, the initial value is 1 */uchar direction;/* the snake is currently moving in the direction of, 2: under , 4: Left, 6: Right, 8: */int (*movedown) (window *win), int (*moveup) (window *win), int (*moveleft) (window *win), int (*moveright) ( WINDOW *win);} Snakest;static Snakest snake = {1,{1,},{GAME_WIDTH/2,},{GAME_HIGTH/2,}, 6};

Complete the initialization of the snake:

int Snakeinit (WINDOW *win) {int i;for (i=0; i<snake.lenparts[0];i++) {MVWPRINTW (win,snake.ypartshead[0], SNAKE.XPARTSHEAD[0], "*");} Snake.movedown = Snakemovedown;snake.moveup   = Snakemoveup;snake.moveleft = snakemoveleft;snake.moveright= Snakemoveright;snake.direction = 6;return 0;}
