贪吃蛇游戏 今天小编带着大家来一起做贪吃蛇游戏，想学习的小伙伴可以自己再敲一遍哦，看看自己能不能理解，有不理解的地方大家可以在文章后面评论，小编会给大家解答的，今天只讲敲一部分，其它的改天再敲。 #include #include #include #define BEG_X 2 #define BEG_Y 1 #define WID 20 #define HEI 20 HANDLE hout; typedef enum {UP, DOWN, LEFT, RIGHT} DIR; typedef struct Snake_body { COORD pos;//蛇身的位置 struct Snake_body *next;//下一个蛇身 struct Snake_body *prev;//前一个蛇身 }SNAKE, *PSNAKE; PSNAKE head = NULL;//蛇头 PSNAKE tail = NULL;//蛇尾 //画游戏边框的函数 void DrawBorder() { int i, j; COORD pos = {BEG_X, BEG_Y}; for(i = 0; i < hei;=""> { SetConsoleCursorPosition(hout, pos); for(j = 0; j < wid;=""> { if(i == 0)//第一行 { if(j == 0) printf('┏'); else if(j == WID - 1) printf('┓'); else printf('━'); } else if(i == HEI - 1)//最后一行 { if(j == 0) printf('┗'); else if(j == WID - 1) printf('┛'); else printf('━'); } else if(j == 0 || j == WID - 1)//第一列或最后一列 printf('┃'); else printf(' '); } ++pos.Y; } } //添加蛇身的函数 void AddBody(COORD pos) { PSNAKE pnew = (PSNAKE)calloc(1, sizeof(SNAKE)); pnew->pos = pos; if(!head) { head = tail = pnew; } else { pnew->next = head;//新创建蛇身的next指向原先的蛇头 head->prev = pnew;//原先的蛇头的prev指向新创建的蛇身 head = pnew;//把新创建的蛇身作为新的蛇头 } SetConsoleCursorPosition(hout, head->pos); printf('◎'); } //蛇身移动的函数 void MoveBody(DIR dir) { PSNAKE ptmp; COORD pos = head->pos; switch(dir) { case UP: if(head->pos.Y > BEG_Y + 1) --pos.Y; else return; break; case DOWN: if(head->pos.Y < beg_y="" +="" hei="" -=""> ++pos.Y; else return; break; case LEFT: if(head->pos.X > BEG_X + 2) pos.X -= 2; else return; break; case RIGHT: if(head->pos.X < beg_x="" +="" (wid="" -="" 2)="" *=""> pos.X += 2; else return; break; } AddBody(pos);//添加了一个新的蛇头 ptmp = tail;//保存当前的蛇尾 tail = tail->prev; if(tail) tail->next = NULL; SetConsoleCursorPosition(hout, ptmp->pos); printf(' '); free(ptmp); } int main() { int ctrl; DIR dir = RIGHT;//初始蛇的方向是向右的 COORD pos = {BEG_X + 2, BEG_Y + HEI / 2}; system('color 0E'); system('mode con cols=90 lines=30'); hout = GetStdHandle(STD_OUTPUT_HANDLE); printf(' ------------贪吃蛇的移动------------'); DrawBorder(); //自定义几个蛇的身体 AddBody(pos); pos.X += 2; AddBody(pos); pos.X += 2; AddBody(pos); pos.X += 2; AddBody(pos); pos.X += 2; AddBody(pos); pos.X += 2; AddBody(pos); pos.X += 2; AddBody(pos); //控制蛇的移动 while(ctrl = getch()) { switch(ctrl) { case 'w': if(dir == DOWN) continue; dir = UP; break; case 's': if(dir == UP) continue; dir = DOWN; break; case 'a': if(dir == RIGHT) continue; dir = LEFT; break; case 'd': if(dir == LEFT) continue; dir = RIGHT; break; case 'q': return 0; } MoveBody(dir); } return 0; } |
