All the cliffs are not fastened, when they are changed there are only 4 types: horizontal (look up or down) and lateral (look up to the left and down to the right).
Sorry for my poor knowledge of the language!

same here

Sorry for the late reply

It can be seen other cliff type more when rotating after placing.
All of you're right, actually It's possible to rotate for 4-type only before placing.
but I meant to develop a plugin that can be rotated after placing

I don't know how could be possible more rotation type without placing.
at least, you can place and then do rotate.

If there're other issue, leave a comment
Thanks.
