How to implement in Unity so that the head of a 2D character follows/follows the cursor? Those. the player moves the cursor, and the head constantly looks in the direction of the cursor. I wanted to implement this through a bone in the skeleton for animations, but I did not figure out how to rotate the bone through the script. Tell me something.

Answer 1

It is necessary:
​​1. Determine the coordinates of the cursor.
2. Create a vector in the direction from the sprite coordinates to the cursor coordinates.
3. Rotate the sprite according to this vector.
Unfortunately, you didn't indicate which of these items you had difficulty with, which is why no one answers you for so long.
