What is the best way to implement character movement in Unity?

Question

Unity

Let's say I have some move code wrapped in the Move method.
What is the best way to call this method?

void FixedUpdate()
{
  if(Input.GetKey(Keycode.A))
    Move;
}

or

void Update()
{
  if(Input.GetKey(Keycode.A))
    Move;
}

Answer 1

It is enough to read how these two methods differ and turn on the brain a little. There is even a picture somewhere in the manuals about the standard game loop, what is called when and when it is BETTER to check.

Answer 2

And if you open the documentation on Input.GetKey, then the question itself will disappear.

Answer 3

If physics is used in move, then FixedUpdate, if not, then just Update.
