c# - 如何判断对象是放大还是缩小？

Question

未开始但已完成放大或缩小。

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

public class Scaling : UnityEngine.MonoBehaviour
{
    public GameObject objectToScale;
    public GameObject lookAtTarget;
    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, Camera objectToScaleCamera)
    {
        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 = lookAtTarget.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 = lookAtTarget.transform.position - objectToScale.transform.position;
                lookPos.y = 0;
                var rotation = Quaternion.LookRotation(objectToScaleCamera.transform.forward);//SwitchCameras.GetCurrentCamera().transform.forward);//Camera.main.transform.forward);
                objectToScale.transform.rotation = Quaternion.Slerp(objectToScale.transform.rotation, rotation, counter / duration);
            }

            yield return null;
        }
    }

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

        while (counter < duration)
        {
            counter += Time.deltaTime;
            targetObj.transform.localScale = Vector3.Lerp(startScaleSize, toScale, counter / duration);

            targetObj.transform.Rotate(Vector3.up * rotationSpeed * Time.deltaTime, Space.Self);

            yield return null;
        }
    }
}

我希望能够知道对象的状态是放大还是缩小。也许使用公共静态布尔？

因此，在其他脚本中，我将能够检查例如 if(Scaling.scaledUp == true) 然后我知道对象已完成放大。下也一样。

所以，你想检查 objectToScale.transform.localScale <= minSize 还是 objectToScale.transform.localScale >= maxSize？所有这些都是公共变量，因此标准的“if”语句应该可以解决问题，但您也可以使用这些内联属性来增加可读性。只要比例一致，就可以使用三个轴中的任何一个来进行检查。
