[开发工具]C++纯字符串操作：小游戏2048的实现

目标：1.实现地图打印、自动调整大小

?????????? 2.实现随机生成

?????????? 3.实现数字移动、合成

?????????? 4.实现重来功能

解决方案：

#include<bits/stdc++.h>
#include<windows.h>
#include<conio.h>
#include<time.h>
#include<string>
#include<cstdlib>

using namespace std;

头文件，没什么好说的

int numbers[10][10]={0},key;
bool fail=false,stop=false;

numbers：数字数组

key：存储按下按键

fail，stop：判断游戏结束

void HideCursor(){
	CONSOLE_CURSOR_INFO cursor_info = {1, 0}; 
	SetConsoleCursorInfo(GetStdHandle(STD_OUTPUT_HANDLE), &cursor_info);
}

void Debug(){
	for(int i = 1;i <= 4;i ++){
		for(int j = 1;j <= 4;j ++)
			cout<<numbers[i][j]<<" ";
		cout<<endl;
	}
}

HideCursor：隐藏光标，增强游戏体验

Debug：调试：输出数组所有数据

void init(){
	for(int i = 1;i <= 4;i ++)
		for(int j = 1;j <= 4;j ++)
			numbers[i][j] = 0;
}

int random(){
	int tmp=rand()%5;
	while(tmp == 0)
		tmp = rand()%5;
	return tmp;
}

void Generate(){
	int x=random(),y=random();
	while(numbers[x][y] != 0){
		x=random();
		y=random();
	}
	numbers[x][y] = 2;
}

init：数组初始化

random：随机返回一个1~5间的整数

Generate：随机在数组一零处生成一“2”

void CelingPrint(){
	for(int i = 0;i < 29;i ++)
		printf("%c",celing[i]);
}

void WallPrint(){
	for(int i = 0;i < 29;i ++)
		printf("%c",wall[i]);
}

int GetNumberLength(int n){
	int cnt=0;
	while(n>0){
		n/=10;
		cnt++;
	}
	return cnt;
}

void NumberPrint(int x,int y){
	printf(" %d",numbers[x][y]);
	for(int i = 0;i < 5-GetNumberLength(numbers[x][y]);i ++)
		printf(" ");
}

void NumberFloorPrint(int x){
	printf("|");
	for(int i = 1;i <= 4;i ++){
		if(numbers[x][i] == 0)
			printf("      |");
		else{
			NumberPrint(x,i);
			printf("|");
		}
	}
}

void OneFloor(int floor){
	WallPrint();
	cout<<endl;
	NumberFloorPrint(floor);
	cout<<endl;
	WallPrint();
	cout<<endl;
	CelingPrint();
}

void MapPrint(){
	printf("  2048控制台版 作者:clzmgl\n");
	CelingPrint();
	cout<<endl;
	for(int i = 1;i <= 4;i ++){
		OneFloor(i);
		cout<<endl;
	}
}

Print类

CeilingPrint：打印“横”

WallPrint：打印“竖”

GetNumberLength：获取一数长度，以便调整打印地图时的空格数

NumberPrint：根据一数长度打印该数在的格子

NumberFloorPrint：打印含有数字的一个楼层

OneFloor：三层（空，数字，空）为一组，打印该组

MapPrint：打印整张地图

				}
	}
	if(key == 80){

				if(numbers[i][j] == numbers[i][j-1]){
					numbers[i][j] *= 2;
					numbers[i][j-1] = 0;
				}
	}
}

Player类

Update：将数组向一侧（上，下，左，右）更新

PlayerControl：根据玩家按下按键设置key状态

Composite：根据key状态将数组进行更新、合成

void FailJudge(){
	fail = true;
	for(int i = 1;i <= 4;i ++)
		for(int j = 1;j <= 4;j ++){
			if(numbers[i][j] == 0)
				fail = false;
			if(numbers[i][j] == 2048)

			stop=true;
		init();

		Generate();
		MapPrint();
	}

	char s;
	if(success){

		scanf("%c",&s);
		if(s == 'n')
			stop=true;
		init();
		system("cls");
		Generate();
		MapPrint();
	}
}

Judge类

FailJudge：判断输 / 赢

Lose：游戏失败

Win：游戏成功

int main(){
	srand(time(NULL));
	HideCursor();
	Generate();
	MapPrint();
	while(1){
		FailJudge();
		Lose();
		Win();
		if(stop)
			break;
		PlayerControl();
		for(int i = 0;i < 4;i ++)
			Composite(); 
		Generate();
		MapPrint();
	}
	return 0;
}

激动人心的主函数

srand：随机数种子

其它没什么好说的
