rigidBody velocity acting up

Questions & Answers

i am making a crouching(more like sliding)script for my FPS, and there is an error. what is wrong?(the error is "Argument 1: cannot convert from ‘UnityEngine.Vector3’ to ‘float’ ") also if i delete “transform.forward” it seems to work, but it only sets a force in one direction.

using UnityEngine;

public class crouch : MonoBehaviour
{
    public CharacterController player;
    public Rigidbody rb;
    public float boost = 120f;
    void Start()
    {
        player = gameObject.GetComponent<CharacterController>();
        rb = gameObject.GetComponent<Rigidbody>();
    }

    void Update()
    {
        if (Input.GetButton("left shift"))
        {

            player.height = 0.2f;
            player.center = new Vector3(0f, 0.5f, 0f);
            rb.velocity = new Vector3(transform.forward * boost * Time.deltaTime, rb.velocity.y, rb.velocity.z);
        }
        else
        {
            player.height = 2.1f;
            player.center = new Vector3(0f, 0f, 0f);
            rb.velocity = new Vector3(0f, 0f, 0f);
        }
    }
}.

the peticular line of code that has the error is:

rb.velocity = new Vector3(transform.forward * boost * Time.deltaTime, rb.velocity.y, rb.velocity.z);

Pretty Sure This Is Right Not Sure Though

You Can’t Have A Vector And A Float On The Same Line So It Would Have To Be Like This

 using UnityEngine;
 
 public class crouch : MonoBehaviour
 {
     public CharacterController player;
     public Rigidbody rb;
     public float boost = 120f;
     void Start()
     {
         player = gameObject.GetComponent<CharacterController>();
         rb = gameObject.GetComponent<Rigidbody>();
     }
 
     void Update()
     {
         if (Input.GetButton("left shift"))
         {
 
             player.height = 0.2f;
             player.center = new Vector3(0f, 0.5f, 0f);
             rb.velocity = new Vector3(transform.forward * Time.deltaTime, rb.velocity.y, rb.velocity.z);
         }
         else
         {
             player.height = 2.1f;
             player.center = new Vector3(0f, 0f, 0f);
             rb.velocity = new Vector3(0f, 0f, 0f);
         }
     }
 }.
