rotate to multiple of 30

rotate30(planeObject)

use this after you rotated an object. if you put it on an object that should rotate use self in the brackets if you use it on global use planeObject if you put it to the rotations.





-- this is the function to rotate it to the correct multiple of 30 foir all three values x, y, z
-- you have to wait a frame and then to wait for the object to rest before using it else oyu have wrong rotation values.
-- this is probably the reson why you get non multiple of 30 because you pressed it to fast, while still rotating.
-- so the new rotation starts when the old is still running. maybe ;)

function rotate30(obj)
   Wait.frames(
      function()

            function()
               local rot = obj.getRotation()
               local rot30 = 0
               for k, v in pairs(rot) do
                  rot30 = v%30
                  if rot30 ~= 0 then
                     if rot30 < 15 then
                        rot[k] = v - v%30
                     else
                        rot[k] = v + 30 - v%30
