使用2参数函数构造std :: thread时出错

Question

I'm creating a simple game using SFML and I got this error:

"std::invoke()": no matching overloaded function found

Failed to specialize function template 'unknown-type std::invoke(_Callable &&,_Types &&...)'

while using following code:

thread function:

void  drawing(charact Hero, sf::RenderWindow window) {
while (window.isOpen()) {
    window.clear();
    window.draw(Hero.hitBox);
    window.display();
    }
}

thread declaration:

std::thread Draw(drawing, Hero, window);

Answer 1

sf::RenderWindow is not copyable (due to inheritance of sf::NonCopyable ), hence drawing cannot be called as-is. Add a reference or use (smart) pointers.
