# Problem with crouching

Hi :D,

so basically I am new to unity and I am trying to learn to add new mechanics. I am creating a 3D game let’s say FPS style. I am following guides on youtube and I managed to make my character move and jump. However, after I added simple code to make my character crouch it appears that it starts to sink a little bit into the floor. I am changing the height of the CharacterController to achieve crouching but after I hit shift to make my character crouch it just sinks even more into the ground and not changing its actual height.

I could leave it like that since it makes an illusion of crouching but I would love to know where I made a mistake. Also because of that when my character is falling down it slows down before hitting the floor which is annoying.

Here is my code:

``````public class PlayerMovement : MonoBehaviour
{
public CharacterController controller;
public float speed = 12f;
public float jumpHeight = 3f;

Vector3 velocity;
public float gravity  = -30f;

public Transform groundCheck;
public float groundDistance = 0.4f;

bool isGrounded;

// Start is called before the first frame update
void Start()
{
controller = gameObject.GetComponent<CharacterController>();
}

// Update is called once per frame
void Update()
{

if (isGrounded && velocity.y < 0)
{
velocity.y = -2;
}
float x = Input.GetAxis("Horizontal");
float z = Input.GetAxis("Vertical");

Vector3 move = transform.right * x + transform.forward * z;

controller.Move(move  * speed * Time.deltaTime);

if(Input.GetButtonDown("Jump") && isGrounded)
{
velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
}

velocity.y += gravity * Time.deltaTime;

controller.Move(velocity * Time.deltaTime);

if (Input.GetKey(KeyCode.LeftShift))
{
controller.height = 0.5f;
speed = 6f;
}
else
{
controller.height = 2.8f;
speed = 12f;
}

}
}
``````

Also as a side question. Sometimes when I change values inside the script it doesn’t seem to change it inside the unity inspector. For example, I changed public float groundDistance = 0.4f; into 0.2f, and after saving in inspector it still was 0.4f.
