There is some problem with my project. The player keeps recolinging Y and attacking even when not hitiing any enemies. My attacking Code:

<code> void Attack() {
        timeSinceAttack += Time.deltaTime;
        if(Input.GetButtonDown("Attack") && attack && timeSinceAttack >= timeBetweenAttack) {
            timeSinceAttack = 0;
            anim.SetTrigger("Attacking");

            audioSource.PlayOneShot(attackSound);

            //* The player is not holding down or up
            if(yAxis == 0 || yAxis < 0 && Grounded()) {

                int _recoilLeftOrRight = pState.lookingRight ? 1 : -1; 
                Hit(sideAttackTransform, SideAttackArea, ref pState.recoilingX,Vector2.right * _recoilLeftOrRight, recoilXSpeed);
                SlashEffectSide(slashEffect,0, sideAttackTransform);
            } else if(yAxis > 0) {
                Hit(upAttackTransform, UpAttackArea, ref pState.recoilingY,Vector2.up, recoilYSpeed);
                SlashEffectAtAngle(slashEffect, 90, upAttackTransform);
            } else if(yAxis < 0 && !Grounded()) {
                Hit(downAttackTransform, DownAttackArea,ref pState.recoilingY,Vector2.down, recoilYSpeed);
                SlashEffectAtAngle(slashEffect, -90, downAttackTransform);

            }
        }
    }
</code>

Sorry for not seeing this earlier, however this doesn’t seem to be an issue with your Attack() method but your Hit() method, or Recoil() method. I suggest you drop the entire PlayerController.cs code for us to take a look at.

What is likely happening is that everytime you attack, your recoilingX or recoilingY bool is being set to true, thus activating the Recoil() method that’s in Update() looking for either to be set to true. Thus, likely your Hit() method isn’t working correctly to prevent all attacks from setting the bool to true.

For 1, check if your Hit() method set’s your recoil bool whenever it detects you have hit an object It would be this code:

    void Hit(Transform _attackTransform, Vector2 _attackArea, ref bool _recoilDir, float _recoilStrength)
    {
        Collider2D[] objectsToHit = Physics2D.OverlapBoxAll(_attackTransform.position, _attackArea, 0, attackableLayer);
        List<Enemy> hitEnemies = new List<Enemy>();

        if(objectsToHit.Length > 0)
        {
            _recoilDir = true;
        } 

Ensure your code looks like this by the end of Part3

    void Hit(Transform _attackTransform, Vector2 _attackArea, ref bool _recoilDir, float _recoilStrength)
    {
        Collider2D[] objectsToHit = Physics2D.OverlapBoxAll(_attackTransform.position, _attackArea, 0, attackableLayer);
        List<Enemy> hitEnemies = new List<Enemy>();

         if(objectsToHit.Length > 0)
        {
            _recoilDir = true;
        } 
        for(int i = 0; i < objectsToHit.Length; i++)
        {
            Enemy e = objectsToHit[i].GetComponent<Enemy>();
            if(e && !hitEnemies.Contains(e))
            {
                e.EnemyHit(damage, (transform.position - objectsToHit[i].transform.position).normalized, _recoilStrength);
                hitEnemies.Add(e);
            }
        }
    }
    void SlashEffectAtAngle(GameObject _slashEffect, int _effectAngle, Transform _attackTransform)
    {
        _slashEffect = Instantiate(_slashEffect, _attackTransform);
        _slashEffect.transform.eulerAngles = new Vector3(0, 0, _effectAngle);
        _slashEffect.transform.localScale = new Vector2(transform.localScale.x, transform.localScale.y);
    }
    void Recoil()
    {
        if(pState.recoilingX)
        {
            if(pState.lookingRight)
            {
                rb.velocity = new Vector2(-recoilXSpeed, 0);
            }
            else
            {
                rb.velocity = new Vector2(recoilXSpeed, 0);
            }
        }

        if(pState.recoilingY)
        {
            rb.gravityScale = 0;
            if (yAxis < 0)
            {                
                rb.velocity = new Vector2(rb.velocity.x, recoilYSpeed);
            }
            else
            {
                rb.velocity = new Vector2(rb.velocity.x, -recoilYSpeed);
            }
            airJumpCounter = 0;
        }
        else
        {
            rb.gravityScale = gravity;
        }

        //stop recoil
        if(pState.recoilingX && stepsXRecoiled < recoilXSteps)
        {
            stepsXRecoiled++;
        }
        else
        {
            StopRecoilX();
        }
        if (pState.recoilingY && stepsYRecoiled < recoilYSteps)
        {
            stepsYRecoiled++;
        }
        else
        {
            StopRecoilY();
        }

        if(Grounded())
        {
            StopRecoilY();
        }
    }
