The script does only zoom in and out, the angle moves, not the player Moves. The script needs to be mounted on the maincamera, and the protagonist needs to be set to the Player's Tag.

Knowledge Points:

1. Finding objects by Findgameobjectwithtag

Gameobject.findgameobjectwithtag ("Player")

2. Understanding of the use of vectors

3. Limit the range of values for a variable

Mathf.clamp (distance, 2, 18)

4.

Input.getmousebuttondown (0/1/2) left/right/middle Key respectively

Input.getaxis ("Mouse Y")//mouse Swipe

Input.getaxis ("Mouse Scrollwheel")//roller Slide

6.RotateAround () function

7.transform.eulerangles.x//euler Angle

Problem: If you use vector.right, a z-axis rotation occurs.
