协程没有正确地进行

嗨我在c#中的脚本的以下协程部分有问题.我得到的错误信息附在屏幕抓取中,似乎是:GetComponent().

using System.Collections;
using UnityEngine;
using UnityEngine.SceneManagement;

public class test: MonoBehaviour
{
    public float model2;
    public float model1;

    public void section1()
    {
        SceneManager.LoadScene("section1", LoadSceneMode.Single);
    }

    public void fade()
    {
       StartCoroutine(colorlerpin());
    }

    public IEnumerator colorlerpin()
    {    
        float ElapsedTime2 = 0.0f;
        float TotalTime2 = 1f;
        while (ElapsedTime2 ().material.color = Color.Lerp(new Color(1f, 1f, 1f, 1f), new Color(1f, 1f, 1f, 0f), (ElapsedTime2 / TotalTime2));
            yield return null;
            //  fades in cutaway
            ElapsedTime2 += Time.deltaTime;
            model2.GetComponent().material.color = Color.Lerp(new Color(1f, 1f, 1f, 0f), new Color(1f, 1f, 1f, 1f), (ElapsedTime2 / TotalTime2));
            yield return null;
        }
    }
}

图像告诉您问题所在:您正在尝试调用GetComponent类型float而不是GameObject或类型的字段MonoBehaviour.

floats是简单的数字,0.5或者2,它们没有组件.您可能希望将类型更改为GameObject/MonoBehaviour
