2D How to make character slowly stop after moving

Questions & Answers

I want my character to slightly slide like it is on ice (but only a little bit).

I feel like what I have should work but it seems when I try to stop the character slowly it just doesn’t and stops straight away. I’ve debugged and the script does recognise when the character stops moving and the body.velocity in the if(is_stopping) statement is getting the correct horizontal/vertical input but doesn’t apply the velocity for some reason.

    void Update()
    {
        // Gives a value between -1 and 1
        horizontal = Input.GetAxisRaw("Horizontal"); // -1 is left
        vertical = Input.GetAxisRaw("Vertical"); // -1 is down

        if(horizontal != 0 || vertical != 0){   //If there is movement keys pressed
            moving = true;
        }

        else if (moving){              //If there is NO movement keys pressed and moving is true
            moving = false;
            is_stopping = true;                 //Set stopping to true to begin the slow stopping

            previous_horizontal_traj = previous_horizontal;     //Record current player direction 
            previous_vertical_traj = previous_vertical;
        }

        if (horizontal != 0 && vertical != 0) // Check for diagonal movement
        {
            // limit movement speed diagonally, so you move at 70% speed
            horizontal *= moveLimiter;
            vertical *= moveLimiter;
        }
        
        //Move the player normally
        if(moving){                
            body.velocity = new Vector2(horizontal * move_speed, vertical * move_speed);
        }

        //Stop the player slowly
        if(is_stopping){
            
            if(stop_speed <= 0.0f){
                is_stopping = false; //character has stopped moving
                stop_speed = 20.0f;  //Reset stop speed
            }

            body.velocity = new Vector2(previous_horizontal_traj * stop_speed, previous_vertical_traj * stop_speed);

            stop_speed = stop_speed - slow_stop_rate;
        }

        previous_horizontal = horizontal;
        previous_vertical = vertical;

    }

Not sure if this is the best way.
Any help is super appreciated!

Try this :

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Movement : MonoBehaviour {
 
     private Rigidbody2D rb;
 
     public float speed; // To control how fast the player moves in the game
 
     private void Start(){
         rb = GetComponent <Rigidbody2D> (); // Get the Rigidbody2D attached to it
     }
 
     private void Update(){
         float horizontal = Input.GetAxis ("Horizontal"); // Gets the horizontal input
         float vertical = Input.GetAxis ("Vertical"); // Gets the vertical input
 
         rb.velocity = new Vector3 (horizontal, vertical) * speed; // Apply them here multiplied by speed
     }
 }
