Im not sure weather or not to use Time.deltaTime I think it would be good to implement it but im not sure how to, I've already tried but I've messed something up

using UnityEngine;
using UnityEngine.SceneManagement;

public class PlayerMovement : MonoBehaviour
{
    [SerializeField] private float horSpeed;
    [SerializeField] private float vertSpeed;
    private Rigidbody2D rb;
    private bool isJumping;

    private void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    private void Update()
    {
        // we store the initial velocity, which is a struct.
        var v = rb.velocity;

        


        if (Input.GetKey(KeyCode.Space) && !isJumping)
        {
            v.y = vertSpeed * Time.deltaTime;
            isJumping = true;
        }

        if (Input.GetKey(KeyCode.A))
            v.x = -horSpeed * Time.deltaTime;

        if (Input.GetKey(KeyCode.D))
            v.x = horSpeed * Time.deltaTime;

        if (Input.GetKey(KeyCode.S))
            v.y = -vertSpeed * Time.deltaTime;

        rb.velocity = v;

        if(Input.GetKey(KeyCode.Escape))
            SceneManager.LoadScene(0);
    }

    private void OnCollisionEnter2D(Collision2D collision)
    {
        isJumping = false;
    }

}

When I tried to add it my character just moved extremely slow

CodePudding user response：

Increase The speed of both vertSpeed and horSpeed or u can use rb.AddForce()

CodePudding user response：

Multiplying your input vectors with Time.DeltaTime makes it frame rate independent.

CodePudding user response：

Try my code. It has no jumping and requires rigidbody and collider2D. I make it for 2d RPG game.

public float speed = 2f;
private Rigidbody2D rb;
private Vector2 moveDelta;
//Inputs
private float x;
private float y;

private void Start()
{
    rb = GetComponent<Rigidbody2D>();      
}


private void FixedUpdate()
{
    //Reset V3
    x = Input.GetAxisRaw("Horizontal");
    y = Input.GetAxisRaw("Vertical");
    moveDelta = new Vector2(x, y);        

    //Facing Toward Mouse
    float dir = (Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position).normalized.x;

    //Rigidbody
    rb.velocity = moveDelta * speed * Time.fixedDeltaTime;

    //Swap side of the sprite
    if(dir > 0)
    {
        transform.localScale = Vector3.one;
    }else if (dir < 0)
    {
        transform.localScale = new Vector3(-1, 1, 1);
    }
}
