问题描述
我制作一个Game类,它有一个窗口。当我尝试执行该函数,VS 2012给我这个错误:
错误1错误C2248:'sf :: NonCopyable: :operator =':无法访问在'sf :: NonCopyable'中声明的私有成员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;
};
静态游戏
#endif
Game.cpp(未完成,具有所有必要的功能用于测试):
#includeGame.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));
}
}
Main.cpp:
#include< SFML / Graphics.hpp>
#includeGame.h
int main()
{
Game.createWindow(Game.getWindowWidth(),Game.getWindowHeight());
while(Game.GameWindow.isOpen())
{
sf ::事件事件;
while(Game.GameWindow.pollEvent(event))
{
if(event.type == sf :: Event :: Closed)
Game.GameWindow.close ;
}
Game.GameWindow.clear();
Game.GameWindow.display();
}
return 0;
}
解决方案即使您可能希望它是初始化:
GameWindow = sf :: RenderWindow(sf :: VideoMode(getWindowWidth getWindowHeight()),Title Goes Here);
并且(如果不明显) sf :: RenderWindow
您可以通过其构造函数在 GAME $ c>的构造函数中初始化RenderWindow $ c> class,或者你可以使它成为一个动态对象:
std :: unique_ptr< sf :: RenderWindow> GameWindow; //你正在使用VS2012所以C ++ 11智能指针是最好的方法这样做
//...skipped一些代码
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。
。
I'm making a Game class with a function that makes a window. When I try to execute the function, VS 2012 gives me this error:
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
Here is my Game.h (unfinished):
#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 (unfinished, has all the necessary functions for testing, though):
#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));
}
}
Main.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;
}
解决方案 This is a copy operation, even though you probably intended it to be initialization:
GameWindow = sf::RenderWindow(sf::VideoMode( getWindowWidth(), getWindowHeight() ), "Title Goes Here");
And (in case that wasn't obvious) sf::RenderWindow
is non-copyable.
You can initialize the RenderWindow via its constructor in the constructor of your GAME
class instead, or you can make it a dynamic object:
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"));
and then use it via GameWindow->
rather than GameWindow.
