用小方块组成圆环（使动态创建物体有父物体 指向中心 ）

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

public class yuan : MonoBehaviour
{

// Use this for initialization
void Start()
{ }
public GameObject cubeModel;
private float r = 5;
private float angle = 0;
public GameObject kong;

void FixedUpdate()
// while (true)
{
if (Input.GetKeyDown(KeyCode.P))
{
for (int i = 0; i < 36; i++)
{
Vector3 center = cubeModel.transform.position;
GameObject cube = GameObject.Instantiate(cubeModel);
kong = GameObject.Find("kongkong");
cube.transform.parent = kong.transform; // 如何使克隆出来的物体不那么杂乱  使其有一个父物体
float hudu = (angle / 180) * Mathf.PI;
float zz = center.z + r * Mathf.Cos(hudu);
float yy = center.y + r * Mathf.Sin(hudu);
cube.transform.position = new Vector3(center.x, yy, zz);
cube.transform.LookAt(center);//指向中心
angle += 10;
}
//       break;

}
