如果我将其他脚本的变量公开，为什么我不能引用另一个脚本前夕呢？

Question

我正在尝试将Scaling脚本引用到ObjectsManipulation脚本中，以便我可以使用Scaling方法和属性。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ObjectsManipulation : MonoBehaviour
{
    public Scaling scaling;

和Scaling脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Scaling : MonoBehaviour
{
    public GameObject objectToScale;
    public float duration = 1f;
    public Vector3 minSize;
    public Vector3 maxSize;
    public bool scaleUp = false;
    public Coroutine scaleCoroutine;

    public void Inits()
    {
     objectToScale.transform.localScale = minSize;
    }

    public IEnumerator scaleOverTime(GameObject targetObj, Vector3 toScale, float duration)
    {
        float counter = 0;
        Vector3 startScaleSize = targetObj.transform.localScale;

        while (counter < duration)
        {
            counter += Time.deltaTime;
            targetObj.transform.localScale = Vector3.Lerp(startScaleSize, toScale, counter / duration);
            if (scaleUp)
            {
                var lookPos = transform.position - objectToScale.transform.position;
                lookPos.y = 0;
                var rotation = Quaternion.LookRotation(lookPos);
                objectToScale.transform.rotation = Quaternion.Slerp(objectToScale.transform.rotation, rotation, counter / duration);
            }
            else
            {
                var lookPos = transform.position - objectToScale.transform.position;
                lookPos.y = 0;
                var rotation = Quaternion.LookRotation(Camera.main.transform.forward);
                objectToScale.transform.rotation = Quaternion.Slerp(objectToScale.transform.rotation, rotation, counter / duration);
            }

            yield return null;
        }
    }
}

脚本ObjectsManipulation附加到GameObject。但是在ObjectsManipulation的Inspector中的编辑器中，我无法添加Scaling脚本试图将Scaling拖动到它但不能。

Answer 1

Scaling currently extends MonoBehaviour which requires that it be attached to a GameObject.

您无法直接将脚本拖动到检查器字段，因为该字段用于该类的实例，而不是对类本身的引用。

你要么需要：

1. 从Scaling类中删除: MonoBehaviour，使其不是Component，然后在new Scaling()中调用ObjectsManipulation，将其分配给字段。
2. 将Scaling脚本附加到GameObject并使用GetComponent<Scaling>()指定对该字段的引用。
