初级贪吃蛇

1.实现蛇的移动。

#include <stdio.h> #include <stdlib.h>#include <time.h>#define SNAKE_MAX_LENGTH 20#define SNAKE_HEAD 'H'#define SNAKE_BODY 'X'#define VLANK_CELL ' '#define SNAKE_FOOD '$'#define WALL_SELL '*'char map[12][12] = {  "************",  "*XXXXH     *",  "*          *",  "*          *",  "*          *",  "*          *",  "*          *",  "*          *",  "*          *",  "*          *",  "************",};int snakeX[SNAKE_MAX_LENGTH]={1,2,3,4,5};int snakeY[SNAKE_MAX_LENGTH]={1,1,1,1,1};int snakeLength = 5;int gameRunning=1;void snakeMove(int snakeX[], int snakeY[]){int headX= snakeX[snakeLength-1];    int headY= snakeY[snakeLength-1];char control=_getch();    switch (control) {    case 'w':        snakeY[snakeLength-1]--;    break;            case 'a':    snakeX[snakeLength-1]--;        break;    case 's':            snakeY[snakeLength-1]++;        break;    case 'd':        snakeX[snakeLength-1]++;    break;        default:        return;    }    if (map[snakeY[snakeLength-1]][snakeX[snakeLength-1]] != VLANK_CELL && map[snakeY[snakeLength-1]][snakeX[snakeLength-1]] != SNAKE_FOOD) {gameOver();}map[snakeY[snakeLength-1]][snakeX[snakeLength-1]]='H';map[headY][headX]='X';map[snakeY[0]][snakeX[0]]=' ';int i;for(i=0;i<snakeLength-1;i++){    snakeY[i]=snakeY[i+1];    snakeX[i]=snakeX[i+1];}snakeY[snakeLength-2]=headY;snakeX[snakeLength-2]=headX;output();} void put_money(void);void output(){    system("cls");  int i = 0 ;  for (i = 0; i < 12; ++i) {int k;for(k = 0;k<12;++k){    printf("%c", map[i][k]);  }  printf("\n");

}
}

void gameOver() {printf("GAME OVER!!\n");gameRunning = 0;}int main(){output();while (gameRunning) {    snakeMove(snakeX,snakeY);}printf("GAME OVER!!\n");}

这样就基本实现了蛇的移动。

2.吃食物和增长蛇身。

#include <stdio.h>#include <stdlib.h>#include <time.h>char BLANK_CHAR      = ' ';char WALL_CHAR       = '*';char SNAKE_HEAD_CHAR = 'H';char SNAKE_BODY_CHAR = 'X';char FOOD_CHAR       = '$';char map[12][13] = {  "************",  "*          *",  "*          *","*          *","*          *",  "*          *",  "*          *",  "*          *",  "*          *",  "*          *",  "*          *",  "************",};int snakeHeadX = 1, snakeHeadY = 1;int snakeBodyX[100] = {0}, snakeBodyY[100] = {0};int snakeBodyLen = 0;int snakeTailIndex = -1;int willBeLonger = 0;int foodX = 0, foodY = 0;int gameRunning = 1;void printMap() {  system("cls");  int i = 0 ;  for (i = 0; i < 12; ++i) {    printf("%s\n", map[i]);      }}void spawnFood() {  // Random food position          foodX = rand() % 10 + 1;  foodY = rand() % 10 + 1;  while (map[foodX][foodY] != BLANK_CHAR) {    foodX = rand() % 10 + 1;foodY = rand() % 10 + 1;  }      map[foodX][foodY] = FOOD_CHAR;}void initGame() {  // Initialize snake      snakeHeadX = snakeHeadY = 1;  map[snakeHeadX][snakeHeadY] = SNAKE_HEAD_CHAR;  snakeBodyLen = 0;      gameRunning = 1;  snakeTailIndex = -1;  willBeLonger = 0;  // Initialize food  spawnFood();  // Initialize game  gameRunning = 1;  printMap();}void gameOver() {system("cls");printf("GAME OVER!!\n");gameRunning = 0;}void snakeMove(char control) {      map[snakeHeadX][snakeHeadY] = BLANK_CHAR;  // record the previous snake head position  int prevSnakeHeadX = snakeHeadX;  int prevSnakeHeadY = snakeHeadY;  switch (control) {   case 'w':snakeHeadX--;break;   case 'a':snakeHeadY--;break;   case 's':snakeHeadX++;break;   case 'd':snakeHeadY++;break;   default:return;  }          if (map[snakeHeadX][snakeHeadY] != BLANK_CHAR && map[snakeHeadX][snakeHeadY] != FOOD_CHAR) {    // DIEDgameOver();  }map[snakeHeadX][snakeHeadY] = SNAKE_HEAD_CHAR;  int moved = 0;  // If willBeLonger, then make it longer  if (willBeLonger) {willBeLonger = 0;moved = 1;// make spaceint i;for (i = snakeBodyLen - 1; i > snakeTailIndex; --i) {  snakeBodyX[i + 1] = snakeBodyX[i];  snakeBodyY[i + 1] = snakeBodyY[i];}snakeBodyX[snakeTailIndex + 1] = prevSnakeHeadX;snakeBodyY[snakeTailIndex + 1] = prevSnakeHeadY;if (snakeTailIndex < 0) snakeTailIndex = 0;map[prevSnakeHeadX][prevSnakeHeadY] = SNAKE_BODY_CHAR;snakeBodyLen++;  }  // Check if ate food  if (snakeHeadX == foodX && snakeHeadY == foodY) {willBeLonger = 1;spawnFood();  }  // Head has already moved, **Move the body**      // if "no body" here or added tail just now, then it needn't move  if (snakeBodyLen <= 0 || moved) return;  map[snakeBodyX[snakeTailIndex]][snakeBodyY[snakeTailIndex]] = BLANK_CHAR;  snakeBodyX[snakeTailIndex] = prevSnakeHeadX;  snakeBodyY[snakeTailIndex] = prevSnakeHeadY;  map[prevSnakeHeadX][prevSnakeHeadY] = SNAKE_BODY_CHAR;  // Move tail index  snakeTailIndex = (snakeTailIndex - 1 + snakeBodyLen) % snakeBodyLen;}int main() {  // Initialize random seed  srand(time(NULL));  initGame();  char control = 0;  while (gameRunning) {control=_getch(); // " %c": the space is used to skip blank character, like '\n'snakeMove(control);printMap();}

这样就完成了基本的通过wasd来控制的贪吃蛇游戏了。
