我对从类返回渲染窗口的方式有些困惑,不确定我的返回类型是否错误或语法是否正确!
我的main.cpp有:
Window Render(800, 600, "Test");
sf::RenderWindow window = Render.Init();
我的课程是:
Window::Window(int x, int y, std::string title){
ResoX = x;
ResoY = y;
Title = title;
}
sf::RenderWindow Window::Init(){
return screen(sf::VideoMode(ResoX,ResoY,Title));
}
该类的标题:
class Window
{
private:
int ResoX, ResoY;
std::string Title;
sf::RenderWindow screen;
public:
Window(int, int, std::string);
sf::RenderWindow Init();
};
我的错误是:
error C2665: 'sf::VideoMode::VideoMode' : none of the 3 overloads could convert all the argument typescould be 'sf::VideoMode::VideoMode(unsigned int,unsigned int,unsigned int)' while trying to match the argument list '(int, int, std::string)'
error C2064: term does not evaluate to a function taking 1 arguments
有谁知道我该如何解决?
最佳答案
来自SFML文档(http://www.sfml-dev.org/documentation/1.6/classsf_1_1VideoMode.php#a9478572db06121f70260e6b9dc21704e)
sf :: VideoMode构造函数声明为:
sf::VideoMode::VideoMode(unsigned int ModeWidth,
unsigned int ModeHeight,
unsigned int ModeBpp = 32
)
这意味着您不能将第三个参数作为字符串传递,可以调用它:
return screen(sf::VideoMode(ResoX,ResoY));
