How to make the bot shoot at the player?

Question

C++ / C#

I want to make the bot shoot at the player. And such questions appeared.
1) How to check if the player is hidden behind some object?
2) And it will be necessary to use LookAt to turn after the player? If so, how can you remove rotation on X (if you use LookAt)?

(I searched the Internet, but did not find what I need)
