我正在创建一个 Game 类,其中包含一个创建窗口的函数。当我尝试执行该函数时,VS 2012 给我这个错误:
Error 1 error C2248: 'sf::NonCopyable::operator =' : cannot access private member declared in class 'sf::NonCopyable' C:\SFML-2.0-rc\include\SFML\Window\Window.hpp 476 1 Faceman
这是我的 Game.h(未完成):
#ifndef FP_MENU
#define FP_MENU
#include <SFML/Graphics.hpp>
class GAME {
public:
sf::RenderWindow GameWindow;
void createWindow();
unsigned int getWindowWidth();
unsigned int getWindowHeight();
void setWindowWidth(unsigned int w);
void setWindowHeight(unsigned int h);
void loadMMenu();
void startGame( bool isTurboMode );
void pause();
void options();
void changeWindowSize( unsigned int x, unsigned int y );
void changeVolume( int i );
void Quit();
private:
unsigned int WINDOW_WIDTH;
unsigned int WINDOW_HEIGHT;
};
static GAME Game;
#endif
Game.cpp(未完成,但具有测试所需的所有功能):
#include "Game.h"
void GAME::setWindowWidth(unsigned int w) {
w = WINDOW_WIDTH;
}
void GAME::setWindowHeight(unsigned int h) {
h = WINDOW_HEIGHT;
}
unsigned int GAME::getWindowHeight() {
return WINDOW_HEIGHT;
}
unsigned int GAME::getWindowWidth() {
return WINDOW_WIDTH;
}
void GAME::createWindow() {
if(getWindowHeight() != 0 && getWindowWidth() != 0)
{
GameWindow = sf::RenderWindow(sf::VideoMode( getWindowWidth(), getWindowHeight() ), "Title Goes Here");
GameWindow.setPosition(sf::Vector2i(50, 50));
}
else
{
setWindowWidth(1024);
setWindowHeight(768);
GameWindow = sf::RenderWindow(sf::VideoMode( getWindowWidth(), getWindowHeight() ), "Title Goes Here");
GameWindow.setPosition(sf::Vector2i(50, 50));
}
}
主要.cpp:
#include <SFML/Graphics.hpp>
#include "Game.h"
int main()
{
Game.createWindow(Game.getWindowWidth(), Game.getWindowHeight());
while (Game.GameWindow.isOpen())
{
sf::Event event;
while (Game.GameWindow.pollEvent(event))
{
if (event.type == sf::Event::Closed)
Game.GameWindow.close();
}
Game.GameWindow.clear();
Game.GameWindow.display();
}
return 0;
}
最佳答案
这是一个复制操作,即使您可能希望它是初始化:
GameWindow = sf::RenderWindow(sf::VideoMode( getWindowWidth(), getWindowHeight() ), "Title Goes Here");
并且(以防万一)sf::RenderWindow
是不可复制的。
您可以改为在 GAME
类的构造函数中通过其构造函数初始化 RenderWindow,或者您可以将其设为动态对象:
std::unique_ptr<sf::RenderWindow> GameWindow; //you are using VS2012 so C++11 smart pointers are the best way to do this
//...skipped some code
GameWindow = std::unique_ptr<sf::RenderWindow>(new sf::RenderWindow(sf::VideoMode( getWindowWidth(), getWindowHeight() ), "Title Goes Here"));
然后通过 GameWindow->
而不是 GameWindow.
使用它。
