c# - 在非 MonoBehaviour 类中使用协程

Question

如何在非 Monobehaviour 类的实例中传递 Monobehaviour？我找到了这个 link其中 TonyLi 提到您可以传递 Monobehaviour 以在类的实例中启动和停止协程，但他没有展示如何做到这一点。他这样做 theEvent.StartEvent(myMonoBehaviour);但他没有显示他从哪里得到 myMonobehaviour。我在互联网上四处张望，但似乎找不到方法。

这是我正在尝试做的事情。我想在一个类的实例中运行一个协程。我还希望能够停止类实例中的协程。我想这样做，这样我的场景中就没有任何拥有大型管理器的对象，这样我就可以将代码重用于我想以这种方式进行乒乓球的任何对象。代码在一个方向上移动一个游戏对象，然后休息一下，然后在另一个方向上移动它，然后再次休息等等。但是我不能从类外启动协程。

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

[RequireComponent (typeof(Image))]
public class SpecialBar : MonoBehaviour {

    public float rangeX;
    public float breakTime;
    public float step;
    float startProgress = 0.5f;
    PingPongGameObject pingPonger;

    Color[] teamColors = new Color[]{new Color(255,136,0),new Color(0,170,255)};

    void Start()
    {

        for(int i = 0; i < teamColors.Length; ++i)
        {
            teamColors[i] = StaticFunctions.NormalizeColor (teamColors[i]);
        }

        pingPonger = new PingPongGameObject (gameObject.transform.position,
            new Vector3(rangeX,0.0f,0.0f),
            gameObject,
            startProgress,
            breakTime,
            step
            );
    }
}

第二个类是我的协程所在的地方。

public class PingPongGameObject
{
    float step;
    Vector3 center;
    Vector3 range;
    GameObject ball;
    float progress;
    float breakTime;
    Vector3 endPos;
    Vector3 oppositePosition;


    public PingPongGameObject(Vector3 _center, Vector3 _range, GameObject _ball, float _startProgress, float _breakTime, float _step)
    {
        center = _center;
        range = _range;
        ball = _ball;
        progress = _startProgress;
        breakTime = _breakTime;
        step = _step;
        endPos = center - range;
        oppositePosition = center + range;
        // This is where I want to start the coroutine
    }

    public IEnumerator PingPong()
    {


        while (progress < 1) {
            progress += Time.deltaTime * step;
            Vector3 newPos = Vector3.Lerp (oppositePosition, endPos, progress);
            ball.transform.position = newPos;
            yield return null;
        }
        Vector3 temp = endPos;
        endPos = oppositePosition;
        oppositePosition = temp;
        progress = 0;
        yield return new WaitForSeconds (breakTime);
        yield return null;
    }

    public float Step
    {
        set{step = value;}
    }

    public void StopCoroutine()
    {
        // This is where I want to stop the coroutine
    }
}

Answer 1

TonyLi mentions that you can pass a Monobehaviour to start and stop coroutines inside a instance of a class, but he does not show how you can do that. He does this

您可以使用 this 关键字来做到这一点。 this 关键字将获取 MonoBehaviour 的当前实例。

在这个例子中有一棵树，它恰好有一个组件MonoScript:

MonoScript 的特定实例可以根据需要(因为它是一个 c# 程序)实例化一个通用的 c# 类，NonMonoScript:

传递 MonoBehaviour 的类:

public class MonoScript : MonoBehaviour
{
    void Start()
    {
        NonMonoScript  nonMonoScript = new NonMonoScript();
        //Pass MonoBehaviour to non MonoBehaviour class
        nonMonoScript.monoParser(this);
    }
}

接收传递MonoBehaviour实例的类:

public class NonMonoScript 
{
    public void monoParser(MonoBehaviour mono)
    {
        //We can now use StartCoroutine from MonoBehaviour in a non MonoBehaviour script
        mono.StartCoroutine(testFunction());

       //And also use StopCoroutine function
        mono.StopCoroutine(testFunction());
    }

    IEnumerator testFunction()
    {
        yield return new WaitForSeconds(3f);
        Debug.Log("Test!");
    }
}

您还可以将 monoParser 函数中的 mono 引用存储在局部变量中以供重复使用。
