Can someone help me?. I couldn't understand the private and animator syntaxes. Can anyone Help me?

Basically, the 4 variables he declared in the beginning of the video all follow the same syntax. They each have am access modifier, a type and a variable name.

The access modifier is used to determine which classes and methods can access this variable. Private simply means that only methods inside the PlayerMovement method can call and access this variable.

The variable type is basically the role of the variable. For exemple, type string is used to store text, and type integers is used to store whole numbers. Animator is a variable type that is used to control the animation of the 3D model.

The variable name is simply used to distinguished different variables of the same type, like moveHorizontal and moveVertical. There are naming conventions tho, so you get bonus point if you use underscores before private variables (_playerAnimator).

Sorry for the late response, hope this helps, Cheers.
