Unity3D -如何测量一堆对象的高度？

using UnityEngine;

public class HeightMeasurement : MonoBehaviour
{
    public GameObject[] objectsToMeasure; // 需要测量高度的对象数组

    private void Start()
    {
        float totalHeight = 0f;

        foreach (GameObject obj in objectsToMeasure)
        {
            // 获取对象的顶部位置
            float topPosition = obj.transform.position.y + obj.GetComponent<Renderer>().bounds.size.y / 2f;

            // 计算高度差并累加
            totalHeight += topPosition - transform.position.y;
        }

        Debug.Log("一堆对象的高度为：" + totalHeight);
    }
}
