Place Object Depending on Swipe Direction

Hi!

I am working on a mobile game and got stuck on one of the features. I am trying to place out blocks of a fixed size with an angle depending on what direction the user swipes from their registered touch. Anyone who knows how to do this? Tried to make some pictures to explain my problem better.

Thank You!

 

You an use

Mathf.Atan2()

to get the angle (in radians) of a given line (eg, startpoint -> endpoint line segment).

Multiply the output by

Mathf.Rad2Deg

and you have degrees you can rotate your block by.
