c语言实现推箱子小游戏

此推箱子游戏可以实现人物移动，箱子移动，人物不出框，自义定文件关卡，重新开始以及回退复位等功能的实现，由于系统或版本问题，关卡和人物及物体未做美化处理，希望美化的可自行美化。

1.所用到的宏

#include <stdio.h>
#include <stdlib.h>
#include <getopt.h>
#define MAX_ROWS 16
#define MAX_CLOS 16
#define MAX_LEVEL 5
#define FILE_NAME_LEN 40
#define ROAD 0  //路 
#define WALL 1  //墙 
#define BOX  2  //箱子 
#define TERM 3  //门 
#define MOUS 4  //老鼠 
#define IGN  224 //无效的键值 
#define LEFT  75 //上下左右相对应的键值 
#define RIGHT 77
#define UP    72
#define DOWN  80
#define MINT MOUS+TERM   //老鼠在门上
#define BINT BOX+TERM    //箱子在门上 
#define QUIT 'q'//退出 
#define RESET 'r'//重新开始 
#define BACK 'b'//回退 
#define NM  0
#define MM  1
#define BM  2
#define MAX_BACK_STEP 10//回退最多的步数

2.变量声明

struct Act{
	int dir;
	int sta;	
};
struct Act acts[MAX_BACK_STEP] = {};
int stepsize = 0;//用于记录回退的数量
int newindex = -1;//用于记录产生一个新的动作 
int board[MAX_ROWS][MAX_CLOS] = {};
int row, col;
int mx = 0,my = 0;//记录老鼠位置 
int bcnt = 0;//记录箱子

3.地图文件开启

void load(int level){//将地图文件存放在Dev-CC文件夹下 
	char fileName[FILE_NAME_LEN] = "";
	sprintf(fileName,"%d.txt",level);
	FILE *fp = fopen(fileName,"r");//只读形式打开文件 
	if(fp == NULL){
		printf("%s文件打开失败\n",fileName);
		exit(-1);//失败退出 
	} 
	fscanf(fp,"%d %d",&row,&col);
	int i,j;
	bcnt = 0;
	for(i=0;i<row;i++){
		for(j=0;j<col;j++){
			fscanf(fp,"%d",&board[i][j]);//读取地图行和列 
			if(board[i][j] == MOUS || board[i][j] == MINT){
				mx = i;
				my = j;
			} 
			else if(board[i][j] == BOX || board[i][j] == BINT){
				++bcnt;
			}
		}
	}
	fclose(fp);
	stepsize = 0;
	newindex = -1;//返回值初始化 
}

4.地图显示及记录模块

//显示地图，记录箱子到达终点 
int show(void){
	int i,j;
	int bs = 0;
	for(i=0;i<row;i++){
		for(j=0;j<col;j++){
			switch(board[i][j]){//画出地图 
				case ROAD:
					printf(" ");
					break;
				case WALL:
					printf("#");
					break;
				case BINT:
					++bs;
				case BOX:
					printf("@");
					break;
				case TERM:
					printf("O");
					break; 
				case MOUS:
				case MINT:
					printf("&");
					break; 				
			}
		}
		printf("\n");
	}
	return bs;
}

5.物体的移动和关卡的延续


int move(int stepx,int stepy){//老鼠和箱子的移动 
	int nx = mx + stepx;
	int ny = my + stepy;
	if (board[nx][ny] == ROAD || board[nx][ny] == TERM){
		board[mx][my] -= MOUS;
		board[nx][ny] += MOUS;
		mx = nx;
		my = ny;
		return MM;
	}
	else if(board[nx][ny] == BOX || board[nx][ny] == BINT){//推着箱子走 
		int nnx = nx + stepx;
		int nny = ny + stepy;//箱子的坐标 
		if(board[nnx][nny] == ROAD || board[nnx][nny] == TERM){
			board[nnx][nny] += BOX;//箱子到达新的地方 
			board[nx][ny] -= BOX;//箱子从原来的地方离开
			board[mx][my] -= MOUS;//老鼠离开 
		    board[nx][ny] += MOUS;//老鼠到达的新的点 
		    mx = nx;
		    my = ny;
		    return BM;
		}
	}
	return NM;
}

6.回退功能的实现（最难部分）

void moveback(int stepx,int stepy){//回退 
	int nx = mx+stepx;
	int ny = my+stepy;
	board[mx][my] -= MOUS;
	board[nx][ny] += MOUS;
	if(acts[newindex].sta == BM){
		int bx = mx-stepx;
		int by = my-stepy;
		board[bx][by] -=BOX;
		board[mx][my] +=BOX;
	}
	mx = nx;
	my = ny;
}

void back(void){
	if(stepsize >0){
		switch(acts[newindex].dir){
			case UP:
				moveback(+1,0);
				break;
			case DOWN:
				moveback(-1,0);
				break;
			case LEFT:
				moveback(0,+1);
				break;
			case RIGHT:
				moveback(0,-1);
				break; 
		}
		--stepsize;
		--newindex;
		if(newindex == -1){
			newindex = MAX_BACK_STEP -1;
		}
	}
}

7.游戏运行主要部分

void play(int level){
	while(1){
		system("cls");//清屏 
		int ret = show();
		if(ret == bcnt){//箱子和被推到终点的箱子数一样时 
			printf("恭喜过关，按任意键进入下一关！！");
			getch();
			return; 
		}
		int key = getch();
		if(key == IGN){
			key = getch();
		}
		if(key == QUIT){//退出 
			printf("GAME OVER\n");
			exit(0);
		} 
		else if(key == RESET){//重新开始 
			load(level);//重新加载地图 
		}
		else if(key == BACK){//回退功能 
			back(); 
		}
		ret = NM;
		switch(key){
			case UP:
				ret = move(-1,0);
				break;
			case DOWN:
				ret = move(+1,0);
				break;
			case LEFT:
				ret = move(0,-1);
				break;
			case RIGHT:
				ret = move(0,+1);
			    break;				
		}
		if(ret == MM || ret == BM){//保存有效动作 用于回退  
			struct Act act = {key,ret}; //记录动作
			++newindex;
			if(newindex>= MAX_BACK_STEP){
				newindex = 0;
			}
			acts[newindex] = act;
			if(stepsize<MAX_BACK_STEP){
				++stepsize;//可以退回的步数+1 
			}
		}
	}
}

//运行函数 
void run(void){
	int level;
	for(level=1;level<=MAX_LEVEL;level++){
		load(level);
		play(level);
	}
}
//主函数 
int main(int argc, char *argv[]) {
	run();
	return 0;
}

8.参考关卡文件（可使用windos记事本以.txt 形式保存，第一列均为空格）
