Veil

Thanks for the help, but I already solved this problem on an ordinary Javascript with IE11 support))

I was trying to create an event of button click which would stop the cube rotation and cause its spinning 90 degrees to the left (if 'left' button clicked) or to the right (if 'right' button clicked) so that the cube turned front strictly with the face, not its edge. I did it according to the docs, but it won't work.
