Getting sprite to follow mouse, weird glitch when using views - c++

Question

I was wondering if anyone could help me. My sprite was following my mouse fine until i started using views i am just starting using SFML, to make the sprite follow my player i used this.
void player::rotateToMouse(sf::Sprite &sprite, sf::RenderWindow &window)
{
this->mouse = sf::Mouse::getPosition(window);
const float PI = 3.14159265;
float a = playerPosition.x - mouse.x;
float b = playerPosition.y - mouse.y;
mouseAngle = (atan2(b, a)) * 180 / PI;
playerSprite.setRotation(mouseAngle + 180);
}
I am adding this code in my update method, like so,
void player::update(sf::RenderWindow &window){
this->rotateToMouse(playerSprite, window);
this->followPlayer();
I am setting my views like this,
void player::followPlayer(){
view.reset(sf::FloatRect(0, 0, 32 + 10, 32 + 10));
view.zoom(15);
view.setCenter(playerSprite.getPosition());
}
and my movement code is this,
if (sf::Keyboard::isKeyPressed(sf::Keyboard::W)){
playerSprite.move(std::cos(3.14159265 * mouseAngle / 180.f) * speed *-1, std::sin(3.14159265 * mouseAngle / 180.f) * speed *-1);
}
else if (sf::Keyboard::isKeyPressed(sf::Keyboard::S)){ //Speed
playerSprite.move(std::cos(3.14159265 * mouseAngle / 180.f) * speed , std::sin(3.14159265 * mouseAngle / 180.f) * speed );
}
this->playerPosition = playerSprite.getPosition();
I can see the sprite is facing slightly off and after a while he starts to spin round randomly, i am quite a noob at c++ and if anyone could help me it would be appreciated.

You need to use sf::RenderTarget::mapPixelToCoords. Basically you need to change how you compute the mouse position from:
this->mouse = sf::Mouse::getPosition(window);
to
this->mouse = window.mapPixelToCoords(sf::Mouse::getPosition(window));
