My charger enemy is not switching to the surprised state until the player is really close to the charger. I am pretty sure the raycast starts outside the charger’s collider and I have tried using a Layermask but it has not worked. using System.Collections; using System.Collections.Generic; using UnityEngine;

public class Charger : Enemy { float timer; [SerializeField] private float ledgeCheckX; [SerializeField] private float ledgeCheckY; [SerializeField] private float chargeSpeedMultiplier; [SerializeField] private float chargeDuration; [SerializeField] private float jumpForce; [SerializeField] private LayerMask whatIsGround;

// Start is called before the first frame update
protected override void Start()
{
    base.Start();
    ChangeState(EnemyStates.Charger_Idle);
    rb.gravityScale = 12f;
}

protected override void UpdateEnemyStates()
{
    if(health <= 0)
    {
        Destroy(gameObject, 0.05f);
    }

    Vector3 _ledgeCheckStart = transform.localScale.x > 0 ? new Vector3(ledgeCheckX, 0) : new Vector3(-ledgeCheckX, 0);
    Vector2 _wallCheckDir = transform.localScale.x > 0 ? transform.right : -transform.right;

    switch (GetCurrentEnemyState)
    {
        case EnemyStates.Charger_Idle:
        Debug.DrawRay(transform.position + _ledgeCheckStart, _wallCheckDir * ledgeCheckX * 10, Color.red);

        if(!Physics2D.Raycast(transform.position + _ledgeCheckStart, Vector2.down, ledgeCheckY, whatIsGround) || Physics2D.Raycast(transform.position, _wallCheckDir, ledgeCheckX, whatIsGround))
        {
            transform.localScale = new Vector2(transform.localScale.x * -1, transform.localScale.y);
        }

        RaycastHit2D _hit = Physics2D.Raycast(transform.position + _ledgeCheckStart, _wallCheckDir, ledgeCheckX * 10);
        if(_hit.collider != null && _hit.collider.gameObject.CompareTag("Player"))
        {
            ChangeState(EnemyStates.Charger_Surprised);
        }

        if(transform.localScale.x > 0)
        {
            rb.velocity = new Vector2(speed, rb.velocity.y);
        }
        else
        {
            rb.velocity = new Vector2(-speed, rb.velocity.y);
        } 
        break;

        case EnemyStates.Charger_Surprised:
            rb.velocity = new Vector2(0, jumpForce);
            ChangeState(EnemyStates.Charger_Charging);
            break;

        case EnemyStates.Charger_Charging:
            timer += Time.deltaTime;
            if(timer < chargeDuration)
            {
                if(Physics2D.Raycast(transform.position + _ledgeCheckStart, Vector2.down, ledgeCheckY, whatIsGround))
                {
                    if(transform.localScale.x > 0)
                    {
                        rb.velocity = new Vector2(speed * chargeSpeedMultiplier, rb.velocity.y);
                    }
                    else
                    {
                        rb.velocity = new Vector2(-speed * chargeSpeedMultiplier, rb.velocity.y);
                    }
                }
                else
                {
                    rb.velocity = new Vector2(0, rb.velocity.y);
                }
            }
            else
            {
                timer = 0;
                ChangeState(EnemyStates.Charger_Idle);
            }
            break;
    }
}

protected override void ChangeEnemyAnimation()
{
    if(GetCurrentEnemyState == EnemyStates.Charger_Idle)
    {
        anim.speed = 1;
    }
    if(GetCurrentEnemyState == EnemyStates.Charger_Charging)
    {
        anim.speed *= chargeSpeedMultiplier;
    }
}

}
