Crouching script

I’m making a first person game and I need to implement crouching. I’ve got the moving and looking down, I just need a crouch script. But I have no clue how to make it. Where do I even put it? A seperate script, the moving script, the looking script? Idk, but this is my moving script.`

public class ControllingScript : MonoBehaviour {

public float walkSpeed = 10f;

// Use this for initialization
void Start () 
{
	Cursor.lockState = CursorLockMode.Locked;
}

// Update is called once per frame
void Update () 
{
	float translation = Input.GetAxis ("Vertical") * walkSpeed;
	float straffe = Input.GetAxis ("Horizontal") * walkSpeed;
	translation *= Time.deltaTime;
	straffe *= Time.deltaTime;

		transform.Translate(straffe, 0, translation);

	if (Input.GetButtonDown("escape"))
		Cursor.lockState = CursorLockMode.None;
}

`

Got any ideas?

Hi.
I assume your player is done the classical way (one camera + capsule collider), like in the Standard Assets ?
Maybe you could reduce the vertical size of the capsule to its half, or something like that ?
I think I would put the crouching code in the moving script.
