I am making a game like flappy bird but sometimes I rotate the pipes however when I rotate them the bird still collides with the original pipe angle as shown by the purple box. Does anyone know how to rotate it so it collides correctly?

Hi,  
With arcade physics, there is only 2 shapes, rectangular and circle, without rotation, so you can’t…
