俄罗斯方块怎样不满行

Question

C++，俄罗斯方块怎样不满行，就能消除
比如空一个格，这一行也能消除
这代码怎么改

#include<iostream>
#include<math.h>
#include<Windows.h>
#include<conio.h>
#include<ctime>
using namespace std;
 
enum DIR
{
    UP,
    RIGHT,
    DOWN,
    LEFT
};
 
time_t start = 0, finish = 0;
 
int _x = 6, _y = 1;//图形生成位置
 
int map[30][16] = { 0 };
 
int sharp[20][8] = {
    {0,0,0,0,0,0,0,0},
    //I形
    {0,0,0,1,0,2,0,3},
    {0,0,1,0,2,0,3,0},

Answer 1

该回答引用gpt：
在俄罗斯方块中，当一行被填满时，需要将该行消除。如果您想让一行不满也能消除，可以考虑在游戏逻辑中添加一些额外的规则。

一种简单的实现方法是，在方块落下到底部时，检查该行是否可以消除。如果该行上有空格，则该行不能消除；否则，该行可以消除。如果您想让玩家手动控制方块落下的位置，可以在方块移动到底部时进行检查。

以下是一个示例实现方法：

// 定义一个游戏区域，包含所有已经落下的方块
vector<vector<int>> gameBoard;

// 定义一个函数，用于检查并消除一行
void checkAndClearRow(int row) {
    bool canClear = true;
    for (int j = 0; j < gameBoard[row].size(); j++) {
        if (gameBoard[row][j] == 0) {
            canClear = false;
            break;
        }
    }
    if (canClear) {
        // 将该行清空
        for (int j = 0; j < gameBoard[row].size(); j++) {
            gameBoard[row][j] = 0;
        }
        // 将该行上面的方块下移一行
        for (int i = row - 1; i >= 0; i--) {
            for (int j = 0; j < gameBoard[i].size(); j++) {
                gameBoard[i + 1][j] = gameBoard[i][j];
            }
        }
        // 将第一行清空
        for (int j = 0; j < gameBoard[0].size(); j++) {
            gameBoard[0][j] = 0;
        }
    }
}

// 定义一个函数，用于将方块落下到底部
void dropBlockToBottom() {
    // 将方块逐行下落，直到不能继续下落为止
    while (canMoveDown()) {
        moveDown();
    }
    // 检查最后一行是否可以消除
    checkAndClearRow(gameBoard.size() - 1);
}

在上面的代码中，gameBoard是一个二维向量，用于表示游戏区域中所有已经落下的方块。checkAndClearRow函数用于检查并消除一行，如果该行可以消除，则将该行上面的方块下移一行，并将第一行清空。dropBlockToBottom函数用于将方块落下到底部，首先将方块逐行下落，然后检查最后一行是否可以消除。

请注意，上面的代码仅供参考，您需要根据实际情况进行修改和优化。
