以半圆轨迹抛射物体

public class test : MonoBehaviour {

Vector3 po;

// Use this for initialization

void Start () {

po=new Vector3((transform.position.x+GameObject.Find("target").transform.position.x)/2,  //取得目的地点和物体坐标之间的中间点

(transform.position.y+GameObject.Find("target").transform.position.y)/2,

(transform.position.z+GameObject.Find("target").transform.position.z)/2);

}

// Update is called once per frame

void Update () {

transform.RotateAround(po, Vector3.up,1f);    //绕某节点转动一定度数

}

}
