错误 c2059：语法错误：'('

Question

我不明白这个错误，它在教程中写得完全相同，但我的错误生成了一个错误。

#include "drawEngine.h"
#include <Windows.h>
#include <iostream>

using namespace std;

DrawEngine::DrawEngine(int xSize, int ySize)
{
    screenWidth = xSize;
    screenHeight = ySize;

    //set cursor visibility to false

    map = 0;
    cursorVisibility(false);
}

DrawEngine::~DrawEngine()
{
    //set cursor visibility to true
    cursorVisibility(true);
}

int DrawEngine::createSprite(int index, char c)
{
    if (index >= 0 && index < 16)
    {
        spriteImage[index] = c;
        return index;
    }

    return -1;
}


void DrawEngine::deleteSprite(int index)
{
    //in this implementation we don't need it
}

void DrawEngine::drawSprite(int index, int posx, int posy)
{
    //go to the correct location
    gotoxy(posx, posy);
    //draw the image with cout
    cout << spriteImage[index];
}

void DrawEngine::eraseSprite(int posx, int posy)
{
    gotoxy(posx, posy);
    cout << ' ';
}
void DrawEngine::setMap(char **data)
{
    map = data;
}

void DrawEngine::createBackgroundTile(int index, char c)
{
    if (index >= 0 && index < 16)
    {
        tileImage[index] = c;
    }
}
void DrawEngine::drawBackground(void)
{
    if (map)
    {
        for (int y = 0; y < screenHeight; y++)
        {
            goto(0, y); // This generates the error

            for (int x = 0; x < screenWidth; x++)
            {

                cout << tileImage[map[x][y]];
            }
        }
    }
}

void DrawEngine::gotoxy(int x, int y)
{
    HANDLE output_handle;
    COORD pos;

    pos.X = x;
    pos.Y = y;

    output_handle = GetStdHandle(STD_OUTPUT_HANDLE);

    SetConsoleCursorPosition(output_handle, pos);
}

void DrawEngine::cursorVisibility(bool visibility)
{
    HANDLE output_handle;
    CONSOLE_CURSOR_INFO cciInfo;

    cciInfo.dwSize = sizeof(CONSOLE_CURSOR_INFO);
    cciInfo.bVisible = visibility;

    output_handle = GetStdHandle(STD_OUTPUT_HANDLE);

    SetConsoleCursorInfo(output_handle, &cciInfo);
}

Answer 1

我认为您的意思是编写 gotoxy(0, y) 而不是 goto(0, y)。

goto 是一个 C++ 关键字，用于跳转到标签，例如：

home:
goto home;    // Loops forever

不过，不要使用它，因为它太容易创建意大利面条式代码了。

Answer 2

goto(0, y) 可能应该是 gotoxy(0, y)。 goto是C语言中的保留关键字，不能用作函数名。

Answer 3

我认为你的意思是gotoxy。 goto 完全是另一回事。
