Graphics / Сoordinates of all vertices

« on: December 10, 2014, 09:56:59 pm »

Hi, I have RectangleShape, how to get the global coordinates of all vertices(top-left,top-right,bottom-left,bottom-right) after rotate?
For example

  shape.setOrigin(size_a/2.f, size_b/2.f);
  shape.setPosition(windowWidth / 2, windowHeight / 2);
  shape.setSize({ size_a, size_b });
  shape.setRotation(10);
 

How to get coordinates of the all vertices?
Thanks.

Graphics / Rotate the shapes relative to center

« on: October 20, 2014, 11:06:21 pm »

Hi, I have RectangleShape, how to rotate it relative to center.
I have tried the following:

shape.setOrigin(size_a/2, size_b/2); //size_a, size_b - size of shape
shape.setPosition(100, 100);
shape.setSize({ size_a, size_b });
shape.setRotation(20);
 

However, rotate relative top-left corner. Am I doing something wrong?
