如何在FSM中创建状态之间的时间间隔

本文关键字：之间 时间 状态 创建 FSM | 更新日期: 2023-09-27 18:25:08

我想在FSM中的状态执行之间创建一个计时器间隔。

我现在所拥有的是相当基础的，因为我对编程还很陌生。如果你能将任何可能的解决方案保持在基本水平上，那就太好了。

public override void Execute()
{
    //Logic for Idle state
    if (dirRight)
        oFSM.transform.Translate(Vector2.right * speed * Time.deltaTime);
    else
        oFSM.transform.Translate(-Vector2.right * speed * Time.deltaTime);
    if (oFSM.transform.position.x >= 2.0f)
        dirRight = false;
    else if (oFSM.transform.position.x <= -2.0f)
        dirRight = true;
    //play animation
    //Transition out of Idle state
    //SUBJECT TO CHANGE
    float timer = 0f;
    timer += Time.time;
    if (timer >= 3f)
    {
        int rng = Random.Range(0, 5);
        if (rng >= 0 && rng <= 1)
        {
            timer = 0;
            oFSM.ChangeStateTo(FSM.States.AtkPatt1);
        }
        else if (rng >= 2 && rng <= 3)
        {
            timer = 0;
            oFSM.ChangeStateTo(FSM.States.AtkPatt2);
        }
        else if (rng >= 4 && rng <= 5)
        {
            timer = 0;
            oFSM.ChangeStateTo(FSM.States.AtkPatt3);
        }
    }
}

如何在FSM中创建状态之间的时间间隔

您需要使用Coroutines，并使用方法WaitForSeconds。

然后你可以做这样的事情：

private float timeToWait = 3f;
private bool keepExecuting = false;
private Coroutine executeCR;
public void CallerMethod()
{
    // If the Coroutine is != null, we will stop it.
    if(executeCR != null)
    {
        StopCoroutine(executeCR);
    }
    // Start Coroutine execution: 
    executeCR = StartCoroutine( ExecuteCR() );
}
public void StoperMethod()
{
    keepExecuting = false;
}
private IEnumerator ExecuteCR()
{
    keepExecuting = true;
    while (keepExecuting)
    {
        // do something
        yield return new WaitForSeconds(timeToWait);
        int rng = UnityEngine.Random.Range(0, 5);
        if (rng >= 0 && rng <= 1)
        {
            oFSM.ChangeStateTo(FSM.States.AtkPatt1);
        }
        else if (rng >= 2 && rng <= 3)
        {
            oFSM.ChangeStateTo(FSM.States.AtkPatt2);
        }
        else if (rng >= 4 && rng <= 5)
        {
            oFSM.ChangeStateTo(FSM.States.AtkPatt3);
        }
    }
    // All Coroutines should "return" (they use "yield") something
    yield return null;    
}
