Unity Player Movement 2D Tutorial With Script

Unity Player Movement 2D Tutorial With Script :- In this tutorial, you’ll discover how to create dynamic player movement for a 2D game in Unity. We’ll guide you through setting up basic horizontal and vertical movement, implementing smooth jumping, and handling player orientation with a flip mechanic. You’ll also learn how to integrate on-screen controls for mobile devices, making your game accessible on both PC and touchscreens. By the end, you’ll have a robust player movement system that enhances gameplay and adapts to different input methods.

Player Movement Script Unity 2D

using UnityEngine;

public class CharacterMovement : MonoBehaviour
{
    private float horizontal;
    private float speed = 8f;
    private float jumpingPower = 16f;
    private bool isFacingRight = true;

    [SerializeField] private Rigidbody2D rb;
    [SerializeField] private Transform groundCheck;
    [SerializeField] private LayerMask groundLayer;

    void Update()
    {
        horizontal = Input.GetAxisRaw("Horizontal");

        if (Input.GetButtonDown("Jump") && IsGrounded())
        {
            rb.velocity = new Vector2(rb.velocity.x, jumpingPower);
        }

        if (Input.GetButtonUp("Jump") && rb.velocity.y > 0f)
        {
            rb.velocity = new Vector2(rb.velocity.x, rb.velocity.y * 0.5f);
        }

        Flip();
    }

    private void FixedUpdate()
    {
        rb.velocity = new Vector2(horizontal * speed, rb.velocity.y);
    }

    private bool IsGrounded()
    {
        return Physics2D.OverlapCircle(groundCheck.position, 0.2f, groundLayer);
    }

    private void Flip()
    {
        if (isFacingRight && horizontal < 0f || !isFacingRight && horizontal > 0f)
        {
            isFacingRight = !isFacingRight;
            Vector3 localScale = transform.localScale;
            localScale.x *= -1f;
            transform.localScale = localScale;
        }
    }
}
