Flipping sprite not working.

[mtbds]

Well, I was trying to flip a sprite using the following code, but it's not working, I'm getting a red square instead of my flipped sprite.

if (pPhysics->getLeft())
        {
                //pRender->getSprite().setScale(-1, 1);
                pRender->getSprite().setTextureRect(sf::IntRect{ (int)m_currentFrame * pRender->getWidth(), 0, pRender->getWidth(), -pRender->getHeight() });
        }
        else
        {
                //pRender->getSprite().setScale(1, 1);
                pRender->getSprite().setTextureRect(sf::IntRect{ (int)m_currentFrame * pRender->getWidth(), 0,  pRender->getWidth(), pRender->getHeight() });

        }

I don't know if I made something wrong on my code, or if it's just a bug...

Peace.

IntRect{ (int)(m_currentFrame + 1) * pRender->getWidth(), 0, -pRender->getWidth(), pRender->getHeight() });

Why do you use a negative height?
