Using rigidbody to move the player

Questions & Answers

I’m trying to use rigidbody.velocity to move my player, however it doesn’t seem to work at all.
Here is the rigidbody settings on the player:

Here are the input settings:

And here is the file controlling player movement:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerController : MonoBehaviour {

	public Rigidbody rb;

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

	}

	void Update () {
		Vector3 desiredVelocity = Input.GetAxis("Horizontal") * transform.right + Input.GetAxis("Vertical") * transform.forward;
		rb.velocity = Vector3.Lerp(rb.velocity, desiredVelocity, Time.deltaTime * 5f);

	}
}

Can someone explain to me why this doesn’t work?

Use this:

Rigidbody rb;
public float speed;

void Start () {
rb = GetComponent<Rigidbody>();
}
void FixedUpdate () {
float mH = Input.GetAxis ("Horizontal");
float mV = Input.GetAxis ("Vertical");
rb.velocity = new Vector3 (mH * speed, rb.velocity.y, mV * speed);
}

You can use this code to move player

    void FixedUpdate ()
    {
        float moveHorizontal = Input.GetAxis ("Horizontal");
        float moveVertical = Input.GetAxis ("Vertical");

        Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);

        rb.AddForce (movement * speed);
    }

Is there no way to move the player in a “snappy” fashion, without the slow responsiveness?
