C# 功能在错误的开关情况下触发

我正在尝试使用枚举实现一个“惰性状态机”，用于简单的敌方AI，但由于某些原因，逻辑无法按预期工作

我需要我的敌人不时停下来，让我处于空闲状态。但当空闲开关开火时，我的敌人不顾移动脚本的另一个状态条件继续移动

我的脚本逻辑有什么问题

目前，您只是没有添加进一步的力/速度。当您进入

idle

状态时，您应该确保

rigiidbody2d

实际上已停止

IEnumerator IdlingTime()
{
    isInIdleState = true;

    // actually stop the movement
    rb.velocity = Vector2.zero;
    // you could even do
    rb.isKinematic = true;

    while (state == State.idle)
    {
        yield return new WaitForSeconds(Random.Range(2, 4));

        isInIdleState = false;
        rb.isKinematic = false;
        state = State.patrol;
    }

    if (isPlayerInSight)
    {
        isInIdleState = false;
        rb.isKinematic = false;
        yield break;
    }
}

或/并在

private void FixedUpdate()
{
    switch(state)
    {
        case State.patrol:
            if (!enemy.isTakingDamage)
            {
                rb.velocity = new Vector2(movingSpeed * speed, rb.velocity.y);
            }
            break;
       
        case State.attack:
            if (!enemy.isTakingDamage)
            {
                rb.velocity = new Vector2(attackDirection.x * attackSpeed, rb.velocity.y);
            }

            if ((Random.Range(0, 100) > 90) && !jumpCooldown && onGround)
            {
                Debug.Log("Прыжок сработал");

                //rb.velocity = new Vector2(rb.velocity.x, rb.velocity.y * jumpForce);
                rb.AddForce(Vector2.up * jumpForce, ForceMode2D.Impulse);
                jumpCooldown = true;
                Invoke("JumpCooldownTime", 1f);
            }
            break;

        case State.idle
            rb.velocity = Vector2.zero;
            break;
    }
}

非常感谢，我对玩家的移动感到困惑，但是敌人的移动速度是恒定的，不需要输入。我不知道可以在Update和FixeUpdate中使用相同的切换情况，这也非常有用。
