使用鼠标滚轮时如何更新光标?

How to update the cursor when I use mousewheel?

我的问题是,当我使用鼠标滚轮移动视图时,光标精灵 留在后面,它不会更新到光标本身,我该如何解决这个问题?

主游戏循环:

this->cursor->Update(window);

if (event->type == sf::Event::MouseWheelMoved)
{
    if (event->mouseWheel.delta == 1)
    {
        this->view->move(sf::Vector2f(0, -25));
        window->setView(*this->view);
        event->mouseWheel.delta = 0;
    }
    else if (event->mouseWheel.delta == -1)
    {
        this->view->move(sf::Vector2f(0, 25));
        window->setView(*this->view);
        event->mouseWheel.delta = 0;
    }
}

游标更新函数:

this->setPosition(static_cast<sf::Vector2f>(sf::Mouse::getPosition(*window)));

查看 SFML 论坛后,我找到了一个答案,说明为什么设置精灵位置功能没有将我的精灵光标设置到我的 mouse.The 原因是 sf::View 与屏幕坐标。

答案:

this->setPosition(window->mapPixelToCoords(sf::Mouse::getPosition(*window)));
