Ruch Unity 2d

// This movement is used for platformer type games
bool jump = false;
float MovementSmoothness = 0.1f;
public float JumpForce;
public PlayerSpeed;
Rigidbody2D rb;

void Start(){
  rb = GetComponent<Rigidbody2D>();
}
void Update()
{
  	horizontal = Input.GetAxisRaw("Horizontal");
  	if(Input.GetKeyDown(KeyCode.W) jump = true;
}

private void FixedUpdate()
{
  	if(jump){
      rb.AddForce(new Vector2(0f, JumpForce));
      jump = false;
    }
  	if(Input.GetKey(KeyCode.LeftShift))// If shift is pressed, sprint
            targetvelocity =  new Vector2(horizontal * PlayerSpeed * 2 * Time.deltaTime, rb.velocity.y);
    else // else go normally
            targetvelocity =  new Vector2(horizonal * PlayerSpeed * Time.deltaTime, rb.velocity.y);
  	// this makes movement much smoother ans satisfying
  	rb.velocity = Vector3.SmoothDamp(rb.velocity,targetvelocity, new Vector3(0,0,0), MovementSmoothness);

Jak zrobić ruch graczy w Unity 2d

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

public class PlayerMovement : MonoBehaviour
{
	// this has jumping, movement, and the code for groundCheck. You must do
    // things yourself in the unity editor to for groundCheck. Code Tested
    // unity 2d platformer
    
    
    public float speed = 5f;
    public float jumpSpeed = 3f;
    private float direction = 0f;
    private Rigidbody2D player;

    public Transform groundCheck;
    public float groundCheckRadius;
    public LayerMask groundLayer;
    private bool isTouchingGround;
    // Start is called before the first frame update
    void Start()
    {
        player = GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void Update()
    {
        isTouchingGround = Physics2D.OverlapCircle(groundCheck.position, groundCheckRadius, groundLayer);
        direction = Input.GetAxis("Horizontal");

        if (direction > 0f)
        {
            player.velocity = new Vector2(direction * speed, player.velocity.y);
        }
        else if (direction < 0f)
        {
            player.velocity = new Vector2(direction * speed, player.velocity.y);
        }
        else
        {
            player.velocity = new Vector2(0, player.velocity.y);
        }

        if (Input.GetButtonDown("Jump") && isTouchingGround)
        {
            player.velocity = new Vector2(player.velocity.x, jumpSpeed);
