Block Rotation Help

In my mod, i want to make it so my custom block does 3 things:

1. If you right-click it, it will look towards you and play a sound
2. If it is hit with a projectile, it will look in the direction the projectile came from
3. If you are trying to break it, it will look towards you

I kinda know how the second one would work, which would be by finding the side that was hit, and changing the direction of the block so the front/face is on the same side that was hit.

And i kinda know how the first and third ones would work, which would be by doing some sort of triangle/cone detection, and if it detect a player, it will turn towards that side

Any help would be greatly appreciated!

P.S, the block has a y-axis rotation
