public class Humanoidlandcontroller : MonoBehaviour
{
Ridgidbody _ridgidbody = null;
[SerialiseFeild] Humanoidlandimput _imput;

vector3 _PlayerMoveImput = vector3.zero;

[Header("movement")]
[SerialiseFeild] float _movementMultiplier = 30.0f;

private void Awake()
{
    _ridgidbody = GetComponent<Ridgidbody>();
    playermove();

    _ridgidbody.AddRelativeForce(_PlayerMoveImput, ForceMode.Force);
}
private void FixedUpdate()
{
    _PlayerMoveImput = GetMoveInput();
    playermove();

    _ridgidbody.AddRelativeForce(_PlayerMoveImput, ForceMode.Force);
}
private vector3 playermove()
{
return new vector3(_imput.MoveImput.x, 0.0, _imput.moveimput.y);
}

private void GetMoveInput()
{
   _PlayerMoveImput = (new vector3(_PlayerMoveImput.x * _movementMultiplier * _ridgidbody.mass,
                                   _PlayerMoveImput.y,
                                   _PlayerMoveImput.z * _movementMultiplier * _ridgidbody.mass ));
}
