Code: [Select]

sf::Vector2f mTP = sf::Vector2f(WMain.GetInput().GetMouseX()-tTurrTankS.GetPosition().x,WMain.GetInput().GetMouseY()-tTurrTankS.GetPosition().y);
float fAngle = atan(mTP.x/mTP.y);
if(mTP.x == 0 && mTP.y == 0)
fAngle = 0;
fAngle *= 180/3.14159;
if(mTP.y >= 0)
fAngle += 180;

tTurrTankS.SetRotation(fAngle);
This is the code I use but,the Turrent rotates like it's center is somewhere else.

You can set the pivot point with SsetCenter (SFML 1.6) org SetOrigin (SFML 2.0).
