这不是一个完整的，但是实现了难点部分，剩下的就是一些UI表现了，关卡设计也很简单，里面都提供了接口

using UnityEngine;
using System.Collections;public class HeroColtrol : MonoBehaviour
{// 圆private float TotalAngle = 360f;// 圆生产预制件public GameObject Bullet;// 需要创建的数量，根据数目可控制关卡难度（自己看一下就知道什么意思了）public float CreateNumber = 5;// 旋转速度public float RotateSpeed = 5;void Update(){// 生产圆if (Input.GetKeyDown(KeyCode.Space)){float angle = TotalAngle / CreateNumber;for (int i = 1; i <= CreateNumber; i++){float curAngle = angle * i;GameObject item = CreateItem();item.transform.RotateAround(transform.position, Vector3.forward, curAngle);}}// 删除所以对象if (Input.GetKeyDown(KeyCode.D)){for (int i = 0; i < transform.childCount; i++){GameObject item = transform.GetChild(i).gameObject;Destroy(item);}}// 旋转if (transform.childCount > 0){transform.Rotate(-Vector3.forward * Time.deltaTime * RotateSpeed);}// 按下鼠标左键创建对象if (Input.GetMouseButtonDown(0)){// Invoke("CreateItem", 1);CreateItem();}}/// <summary>/// 创建一个圆/// </summary>/// <returns></returns>private GameObject CreateItem(){GameObject item = Instantiate(Bullet);item.transform.localPosition = new Vector3(0f, -2, 0f);item.transform.SetParent(transform);item.AddComponent<RotateItem>();return item;}}

using UnityEngine;
using System.Collections;public class RotateItem : MonoBehaviour
{private LineRenderer Line;void Awake(){Line = transform.GetComponent<LineRenderer>();}void FixedUpdate(){// 设置线的1index对应的坐标Line.SetPosition(1, transform.position);}
}
