如何随时间启动协程？

Question

using System;
using System.Collections;
using System.Collections.Generic;
using TMPro;
using UnityEngine;
using UnityEngine.UI;

public class PlayerMouthSpeechController : MonoBehaviour
{
    public TMP_Text[] texts;
    public bool startTalking = false;
    public float talkTime;
    public float duration;
    [Range(0, 100)]
    public float valueRange;
    private SkinnedMeshRenderer bodySkinnedMeshRenderer;
    //private bool isTalking = true;

    // Start is called before the first frame update
    void Start()
    {
        bodySkinnedMeshRenderer = GetComponent<SkinnedMeshRenderer>();
    }

    // Update is called once per frame
    void Update()
    {
        /*if (startTalking && isTalking)
        {
            StartCoroutine(AnimateMouth());
            StartCoroutine(TalkTime());

            isTalking = false;
        }

        if(startTalking == false && isTalking == false)
        {
            isTalking = true;
        }*/
    }

    //Lerp between startValue and endValue over 'duration' seconds
    private IEnumerator LerpShape(float startValue, float endValue, float duration)
    {
        float elapsed = 0;
        while (elapsed < duration)
        {
            elapsed += Time.deltaTime;
            float value = Mathf.Lerp(startValue, endValue, elapsed / duration);
            bodySkinnedMeshRenderer.SetBlendShapeWeight(0, value);
            yield return null;
        }
    }

    //animate open and closed, then repeat
    public IEnumerator AnimateMouth()
    {
        while (startTalking == true)
        {
            yield return StartCoroutine(LerpShape(0, valueRange, duration));
            yield return StartCoroutine(LerpShape(valueRange, 0, duration));
        }
    }

    public IEnumerator TalkTime()
    {
        yield return new WaitForSeconds(talkTime);

        startTalking = false;
    }
}

我之前用太多标志搞砸了，在 Update() 中也搞砸了。

我想做一些简单的事情。为了能够从任何其他脚本调用 AnimateMouth 方法并且 AnimateMouth 方法也将获得一个浮点数，这将是嘴部动画的时间。类似：

StartCoroutine(AnimateMouth(4f));

但我把这一切都搞砸了。可能是让 AnimateMout 公共静态，或者在从另一个脚本调用时首先引用 PlayerMouthSpeechController，然后将其称为：

playerMouthSpeechController.AnimateMouth(); 

然后一些东西会启动 AnimatedMouth 协程。但我又搞砸了。

更新：

这几乎可以完美地按照我的意愿运行，但每次我希望播放器开始说话时，我都需要使用 StartCoroutine，但它可以正常工作。

using System;
using System.Collections;
using System.Collections.Generic;
using TMPro;
using UnityEngine;
using UnityEngine.UI;

public class PlayerMouthSpeechController : MonoBehaviour
{
    public TMP_Text[] texts;
    public float duration;
    [Range(0, 100)]
    public float valueRange;

    private bool startTalking = false;
    private SkinnedMeshRenderer bodySkinnedMeshRenderer;

    // Start is called before the first frame update
    void Start()
    {
        bodySkinnedMeshRenderer = GetComponent<SkinnedMeshRenderer>();
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    //Lerp between startValue and endValue over 'duration' seconds
    private IEnumerator LerpShape(float startValue, float endValue, float duration)
    {
        float elapsed = 0;
        while (elapsed < duration)
        {
            elapsed += Time.deltaTime;
            float value = Mathf.Lerp(startValue, endValue, elapsed / duration);
            bodySkinnedMeshRenderer.SetBlendShapeWeight(0, value);
            yield return null;
        }
    }

    //animate open and closed, then repeat
    public IEnumerator AnimateMouth(float TimeToTalk)
    {
        startTalking = true;

        StartCoroutine(TalkTime(TimeToTalk));

        while (startTalking == true)
        {
            yield return StartCoroutine(LerpShape(0, valueRange, duration));
            yield return StartCoroutine(LerpShape(valueRange, 0, duration));
        }
    }

    private IEnumerator TalkTime(float TalkTime)
    {
        yield return new WaitForSeconds(TalkTime);

        startTalking = false;
    }
}

例如在另一个脚本中使用它：

在顶部：

public PlayerMouthSpeechController blendShapeController;

和

StartCoroutine(blendShapeController.AnimateMouth(10f));

我希望我能以某种方式做到我不会每次都启动协程，它会自动启动协程，我只会这样做：

blendShapeController.AnimateMouth(10f);

它会在 PlayerMouthSpeechController 中启动协程。

我想要的工作解决方案：

using System;
using System.Collections;
using System.Collections.Generic;
using TMPro;
using UnityEngine;
using UnityEngine.UI;

public class PlayerMouthSpeechController : MonoBehaviour
{
    public TMP_Text[] texts;
    public float duration;
    [Range(0, 100)]
    public float valueRange;

    private bool startTalking = false;
    private SkinnedMeshRenderer bodySkinnedMeshRenderer;

    // Start is called before the first frame update
    void Start()
    {
        bodySkinnedMeshRenderer = GetComponent<SkinnedMeshRenderer>();
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    //Lerp between startValue and endValue over 'duration' seconds
    private IEnumerator LerpShape(float startValue, float endValue, float duration)
    {
        float elapsed = 0;
        while (elapsed < duration)
        {
            elapsed += Time.deltaTime;
            float value = Mathf.Lerp(startValue, endValue, elapsed / duration);
            bodySkinnedMeshRenderer.SetBlendShapeWeight(0, value);
            yield return null;
        }
    }

    //animate open and closed, then repeat
    public void AnimateMouth(float TimeToTalk)
    {
        StartCoroutine(StartAnimating(TimeToTalk));
    }

    private IEnumerator StartAnimating(float TimeToTalk)
    {
        startTalking = true;

        StartCoroutine(TalkingTime(TimeToTalk));

        while (startTalking == true)
        {
            yield return StartCoroutine(LerpShape(0, valueRange, duration));
            yield return StartCoroutine(LerpShape(valueRange, 0, duration));
        }
    }

    private IEnumerator TalkingTime(float TalkTime)
    {
        yield return new WaitForSeconds(TalkTime);

        startTalking = false;
    }
}

在其他脚本中做参考：

public PlayerMouthSpeechController blendShapeController;

开始

blendShapeController.AnimateMouth(10f);
