How to make the player turn behind the cursor like in Top Down Shooter Unity3D 2019?

Question

C++ / C#

I am 12 years old (Lol) learning to program on sharps, I climbed a bunch of forums and videos, but I still didn’t understand how to turn the player, let’s say, so that he looked in the direction of the mouse cursor.
3D project - consider!

Please, help. In Russia, it seems to me that programming is very tight, but I generally keep quiet with Unity & Unreal Engine.
For example, games with a player turn can take Hotline Miami.
(And yes, if you can, please advise some Russian sites and tutorials on C # Unity 2019)

Answer 1

Experiment with the ScreenToWorldPoint() function .
There is also ScreenPointToRay() .
Further, having a coordinate in 3D space, one can easily calculate the character's rotation towards this point.
