VS Express无法正确编译代码（？）[保留]

问题描述 投票：-2回答：1

所以我曾经使用Code :: Blocks IDE，并且非常喜欢它。最近，我切换到了Visual Studio。我下载了VS Express，速度为600mb，每天只能使用1gb数据，没有Wi-Fi，所以那是我唯一的选择，我在Code :: Blocks中插入了正确编译的相同代码，需要一些调整才能使其在VS中工作，但是当我最终检查它时，输出完全不同。它不是命令行Tetris，而是出现故障，并用奇怪的字符填充了命令提示符。

这是我为使其在VS中工作而进行了一些调整的代码：

#include <iostream>
#include <time.h>
#include <string>
#include <windows.h>
using namespace std;

int nScreenHeight = 30;
int nScreenWidth = 80;
int nFieldWidth = 10;
int nFieldHeight = 25;
unsigned char *pField = NULL;
wstring tetromine[7];

int currentPiece = 0;
int currentRotation = 0;
int currentX = (nFieldWidth/2);
int currentY = 0;
unsigned int score = 0;

int pieceCounter = 0;
int speed = 20;
int speedCounter = 0;
bool forcePieceDown =false;
bool key[4];
bool shiftGridDown = false;

int rotate(int px,int py,int r)
{
    switch(r/90)
    {
    case 0:
        return py*4+px;//0 degs
    case 1:
        return 12+py - (px*4);//90 degs
    case 2:
        return 15 - (py*4) - px;//180 degs
    case 3:
        return 3 - py + (px*4);//270 degs
    }
    return 0;
}

int doesPieceFit(int id,int rot, int x, int y)
{
    for(int px = 0;px<4;px++){
        for(int py = 0;py<4;py++){
            int pi = rotate(px,py,rot);
            int fi = (y+py) * nFieldWidth + (x+px);
            if(x + px>= 0 && x+px < nFieldWidth){
                if(tetromine[id][pi] == L'X' && pField[fi]!=0){
                    return false;
                }
            }
        }
    }
    return true;
}

    bool line = true;
    int lines = 0;

                line &= true;

        }

您混合使用窄字符和宽字符。您对(LPCWSTR)screen的呼叫中的WriteConsoleOutputCharacter强制转换表示存在某些问题。

在这种情况下，screen是char，但您希望它改为wchar_t。您已经在wstring和tetromine前缀字符串中使用了L。您只需要确保其余代码也使用宽字符即可。
