Movement Script Issues

Scripting
,
1

Hello, this will be my first post here.
QQ, I’m using this script to control my player movement and the animations that will play for idle, walking, jumping, and falling.
For some reason, whenever the character walks to the left the falling animation will play instead of the walking animation.
I’ve tried changing the box collider to see if that was the issue as well as deleting this portion of the code:

else if (rb.velocity.y < -.1f)
{
state = MovementState.falling;
}

It stopped the falling animation from playing and the walking animation was able to play when the character walked to the left.

Any assistance would be greatly appreciated.

public class PlayerMovement : MonoBehaviour
{
    // This variable is for accessing the Rigidbody2D class
    private Rigidbody2D rb;
    // This variable is for accessing the BoxCollider2D class
    private CapsuleCollider2D coll;
    // This variable is for accessing the SpriteRenderer class
    private SpriteRenderer sprite;
    // This variable is for accessing the Animator class

    [SerializeField] private float moveSpeed = 7f;

    private Vector2 vecGravity;

    //
    private enum MovementState { idle, walking, jumping, falling }

    // Start is called before the first frame update
    private void Start()

        }
        if (rb.velocity.y < 0)
        {
            rb.velocity -= vecGravity * fallMultiplier * Time.deltaTime;

        MovementState state;

        if (dirX > 0f)
        {
            state = MovementState.walking;
            sprite.flipX = false;
        }
        else if (dirX < 0f)
        {
            state = MovementState.walking;
            sprite.flipX = true;

        {
            state = MovementState.jumping;
        }
        else if (rb.velocity.y < -.1f)
        {
            state = MovementState.falling;
        }

        anim.SetInteger("state", (int)state);
    }

    private bool IsGrounded()
    {
        return Physics2D.BoxCast(coll.bounds.center, coll.bounds.size, 0f, Vector2.down, .1f, jumpableGround);
    }
}

Debug.log the velocity to see what the value actually is. Then base the solution around that. Maybe it’s because gravity affects the velocity as well?
And you can check if the player is grounded, and if not, trigger the falling and jumping. This way you can make sure the player is on the ground

Thanks I looked into it using Debug.log on the y velocity and found that this ```
if (rb.velocity.y < 0)
{
rb.velocity -= vecGravity * fallMultiplier * Time.deltaTime;
}

was affecting the gravity and velocity.
Changing the code to this fixed the issue.

if (rb.velocity.y < -.1f)
{
rb.velocity -= vecGravity * fallMultiplier * Time.deltaTime;
}


Thanks again!
