How to make rigid body move position move the transform of an object

Questions & Answers
1

I am making a first person shooter and I am using rigid body Move Rotation to rotate my character due to physics in that scene. It’s moving the object but not the transform of the object do when I use Rigid body MovePosition for my wasd controls, it works from its original point instead of where the object is looking. Is there any way to fix this. I have tried doing a transform command separately but it didn’t work. I am using a player controller script for my values and my player motor script to do the grunt work. I am using all of the default unity libraries. Here is the player controller script:

[RequireComponent(typeof(PlayerMoter))]

public class PlayerControler : MonoBehaviour {
	
	[SerializeField]
	private float speed = 5f;
	[SerializeField]
	private float rotSpeed = 5f;

	[SerializeField]
	private PlayerMoter moter;

	void Start () 
	{
		moter = GetComponent<PlayerMoter>();	
	}
	

	void Update () 
	{
		float Xmovment = Input.GetAxisRaw ("Horizontal");
		float Zmovment = Input.GetAxisRaw ("Vertical");

		float mouseX = Input.GetAxisRaw ("Mouse X");




		Vector3 finalVelocity = new Vector3(Xmovment, 0f, Zmovment).normalized * speed;
		Vector3 finalRotVelocit = new Vector3 (0f, mouseX, 0f).normalized * rotSpeed;
		Quaternion finalRotQuat = Quaternion.Euler (finalRotVelocit*Time.fixedDeltaTime);

		moter.setVelocity (finalVelocity); 
		moter.setRotation (finalRotQuat);
	}
}

here is the player motor script:

public class PlayerMoter : MonoBehaviour {

	Rigidbody rb;
	Vector3 velocity = Vector3.zero;
	Quaternion rotaion;


	void Start () {
		
		rb = GetComponent<Rigidbody> ();	
	}
	

	void FixedUpdate () 
	{
		move ();
		rotate ();
	}

	public void setVelocity(Vector3 direction)
	{
		velocity = direction;
	}

	public void setRotation(Quaternion rot)
	{
		rotaion = rot;	
	}

	public void move()
	{
		if(velocity!=Vector3.zero)
		{
			rb.MovePosition (rb.position + velocity * Time.fixedDeltaTime);	
		}
	}

	public void rotate()
	{
		
			

		rb.MoveRotation (rb.rotation * rotaion);


	}

}

Thanks for any help I can get.

Just an idea, not a solution

Minor issue: line 31 uses Time.fixedDeltaTime, you should be using Time.deltaTime (in Update() for sure but also this is better for FixedUpdates anyway, according to the docs).

But that minor issue raised an idea: your PlayerMotor script calles move() and rotate() in FixedUpdate, but your PlayerController uses Update. This smells like dodgy code to me! I would reccomend processing all the motion in Update or all in FixedUpdate. This weird hybrid of your’s might be confusing the physics engine.
