Graphics / Rotations About Center of Circle
« on: October 04, 2020, 02:13:49 am »
Hi there,
This is likely a very dumb question, but based on reading all the documentation of rotation and setOrigin, this isn't clear to me why the behavior is such.
My question is based on the code below. It seems as though rotating a circle about its center (which seemingly should have no effect) actually moves the circle!
sf::CircleShape c( 100.f );
c.setOrigin(sf::Vector2f(100.f, 100.f));
c.rotate(45);
If I render that graphic, the circle is not fixed. Instead, only its bottom right quadrant appears in the window.
What happened here?
