Question

我正在使用C ++（使用SFML2.2库，Xcode 6.1.1）编写棋盘游戏。我创建了两个类：块和板。我们的想法是在板内创建一个4x4的块矢量。代码如下：

在block.h中

#ifndef __Game1024__block__
#define __Game1024__block__
#include <stdio.h>
#include <iostream> 
#endif /* defined(__Game1024__block__) */

using namespace std;

class block{
public:
    sf::RectangleShape rect;
    sf::Text text;
    block();
    block(const int X,const int Y,const double size, const double blockSize, const double charSize, const int value, const sf::Color fillColor, const sf::Color textColor);
};

在block.cpp

中

#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>
#include <string>
#include <sstream>
#include "block.h"

using namespace std;

block::block(){}

block::block(const int X,const int Y,const double size, const double blockSize, const double charSize, const int value, const sf::Color fillColor, const sf::Color textColor){

    double centerX = (X+0.5)*size;
    double centerY = (Y+0.5)*size;
    stringstream ss;
    ss << value;
    string sval = ss.str();

    rect.setSize(sf::Vector2f(blockSize,blockSize));
    rect.setOrigin(blockSize/2.0, blockSize/2.0);
    rect.setPosition(centerX, centerY);
    rect.setFillColor(fillColor);

    text.setStyle(sf::Text::Bold);
    text.setCharacterSize(charSize);
    text.setString(sval);
    text.setColor(textColor);
    text.setOrigin(text.getLocalBounds().width/2.0, text.getLocalBounds().height);
    text.setPosition(centerX, centerY);
 }

在board.h中

#ifndef __Game1024__board__
#define __Game1024__board__
#include <stdio.h>
#endif /* defined(__Game1024__board__) */
#include <vector>
#include "block.h"
using namespace std;

class board{
private:
    int winSizeX;
    int winSizeY;
    int margin;
    double charSize;
public:
    vector<vector<block>> matrix;
    board();
    board(int winSizeX_,int winSizeY_,int margin_, double charSize_);
    void draw();
};

并在board.cpp

#include "board.h"
//#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>
#include "block.h"
using namespace std;

board::board(){}

board::board(int winSizeX_,int winSizeY_,int margin_, double charSize_){
    winSizeX = winSizeX_;
    winSizeY = winSizeY_;
    margin = margin_;
    charSize = charSize_;
    matrix = vector<vector<block>>(4,vector<block>(4));

    double size = winSizeX/4.0; // = 256
    double blockSize = size - 2*margin;
    const sf::Color fillColor = sf::Color::Red;
    const sf::Color textColor = sf::Color::White;

    sf::Font font;
    if(!font.loadFromFile("./sansation.ttf")){
        exit(EXIT_FAILURE);
    };
    for (int i = 0; i < 4; ++i){
        for (int j = 0; j < 4; ++j){
            int value = 4*j + i + 1;
            matrix[i][j] = block(i,j,size,blockSize, charSize,value,fillColor,textColor);
            matrix[i][j].text.setFont(font);
            matrix[i][j].text.setOrigin(matrix[i][j].text.getLocalBounds().width/2.0,b[i][j].text.getLocalBounds().height);
        }
    }
}

错误来自 board.cpp

matrix[i][j] = block(i,j,size,blockSize, charSize,value,fillColor,textColor);

一个奇怪的事情是当我键入matrix [i] [j] = block时，我的IDE（Xcode）的自动填充将生成

matrix[i][j] = block(<#const int X#>, <#const int Y#>, <#const double size#>, <#const double blockSize#>, <#const double charSize#>, <#const int value#>, <#const int fillColor#>, <#const int textColor#>)

构造函数块的最后两个参数从 sf :: Color 类型更改为 int 。

如果我在 main.cpp 文件中创建4x4块矢量并调用块的构造函数，则没有错误...

有任何帮助吗？提前致谢！

谢谢@molbdnilo

我犯了一个愚蠢的错误，我忘了将SFML标题包含在＆＃34; block.h＆＃34;

#include <SFML/Graphics.hpp>

现在问题解决了！谢谢你的所有建议。我是C ++项目的新手，请随时在代码中说出我的所有不良做法。非常有帮助！

没有匹配的构造函数用于初始化＆＃34; Type＆＃34;
