panel.angle

Range:

Type:

Remarks:

• For displaying text or numbers, and for reacting on mouse events angle must be zero.
• The rotation center can be set by center_x.
• All panel elements, except for the Digits element, rotate with the panel.

Example:

PANEL* pan;

// rotate a panel about its center
function pan_rotate(p)
{
  pan = p; // set the panel pointer from the function parameter
  pan.center_x = pan.size_x * 0.5; // set the rotation center at the panel center
  pan.center_y = pan.size_y * 0.5;
  while (pan.angle < 360)          // one full rotation
  { 
     pan.angle += 10*time_step;
     wait(1);
     pan = p; // local variables are preserved during wait(), global pointers aren't
  }
  pan.angle = 0; 
}
