开篇废话：
这个项目准备分四部分介绍：
一：创建可旋转的“3D球”：3D语音天气球（源码分享）——创建可旋转的3D球
二：通过天气服务，从网络获取时实天气信息并动态生成“3D球”
三：Android语音服务和Unity的消息传递
四：Unity3D端和Android端的结合
关于项目的详细介绍和3D球的创建请看上面第一篇文章（重要）
今天主要讲解如何通过获取实时的天气信息去动态的创建3D球。效果图如下：
左边是Unity做出后在电脑上运行效果图（本节需要实现的效果）
右边是Unity结合Android和语音控制之后在手机运行的效果图（所有都介绍完后的最终效果）：

} // 获取天气信息

{

string url = "http://www.weather.com.cn/data/cityinfo/" + city.getCityID() +".html";
// 通过url来给小球赋值
StartCoroutine(GET(url,city,text));
}
IEnumerator GET(string url, City city, GameObject text)
{
WWW www = new WWW (url);
yield return www;
//GET请求失败
if (www.error != null)
{
Debug.Log ("error is :" + www.error);
}
//GET请求成功
else
{

// 解析天气信息，给对象赋值
city.parseJson (www.text);
// 根据当前city对象中的属性给小球复制
TextMesh tm = (TextMesh)text.GetComponent<TextMesh> ();
ChangeColor changeColor = text.GetComponent<ChangeColor>();
// 判断当前对象是城市还是省份来分别赋值
if (isCity) {
tm.text = city.getName ();
changeColor.name = city.getName();
changeColor.id = city.getCityID();
changeColor.tempture = city.getTempture();
}
else
{
tm.text = city.getProName();
changeColor.name = city.getProName();
changeColor.tempture = city.getTempture();
}
// 设置当前颜色
tm.color = city.getWeatherColor();
// 根据城市和省份的不同来判断是否设置图片
foreach (Transform child in text.transform) {
if (isCity) {
if (child.tag == "pic1") {
//Debug.Log(getPicPath(city.getImg1()));
Texture2D pic = (Texture2D)Resources.Load(Util.getPicPath(city.getImg1()));
child.renderer.material.shader = Shader.Find ("Unlit/Transparent");
child.renderer.material.mainTexture = (Texture)pic;
}
else if (child.tag == "pic2")
{
//Debug.Log(getPicPath(city.getImg2()));

}
}
else
{
child.active = false;
}
}
// 设置小球大小
text.transform.localScale = city.getSize();
text.GetComponent<ChangeColor>().oldScale = text.transform.localScale;
}
}显示单个城市详细天气信息的方法和上面大同小异，这里我就不过多介绍了。一：创建可旋转的“3D球”：3D语音天气球（源码分享）——创建可旋转的3D球
二：通过天气服务，从网络获取时实天气信息并动态生成“3D球”
三：Android语音服务和Unity的消息传递
四：Unity3D端和Android端的结合
