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（源代码分享）——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”：3D语音天气球（源代码分享）——通过天气服务动态创建3D球
三：Android语音服务和Unity的消息传递：3D语音天气球（源代码分享）——在Unity中使用Android语音服务
四：Unity3D端和Android端的结合：3D语音天气球（源代码分享）——完结篇
关于项目的具体介绍和3D球的创建请看上面第一篇文章（重要）
今天主要解说怎样通过获取实时的天气信息去动态的创建3D球。效果图例如以下：
左边是Unity做出后在电脑上执行效果图（本节须要实现的效果）
右边是Unity结合Android和语音控制之后在手机执行的效果图（全部都介绍完后的终于效果）：

}如今能够依据它来动态生成我们的3D球了。
上篇文章已经具体介绍了怎样在大球中生成平均分布的小球。接下来的任务就是为生成的小球gameobject设置各种属性：
// 获取天气信息
public void getWeather(City city, GameObject text)
{
// 依据城市id得到获取天气服务的url
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
{
//Debug.Log(www.text);
// 解析天气信息，给对象赋值
city.parseJson (www.text);
// 依据当前city对象中的属性给小球复制
TextMesh tm = (TextMesh)text.GetComponent<TextMesh> ();
ChangeColor changeColor = text.GetComponent<ChangeColor>();
// 推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();
// 依据城市和省份的不同来推断是否设置图片
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()));
Texture2D pic = (Texture2D)Resources.Load(Util.getPicPath(city.getImg2()));
child.renderer.material.shader = Shader.Find ("Unlit/Transparent");
child.renderer.material.mainTexture = (Texture)pic;
}
else
{
TextMesh tm2 = (TextMesh)child.GetComponent<TextMesh> ();
tm2.text = city.getDetailsName ();
tm2.color = city.getWeatherColor();
}
}
else
{
child.active = false;
}
}
// 设置小球大小
text.transform.localScale = city.getSize();
text.GetComponent<ChangeColor>().oldScale = text.transform.localScale;
}
}。。
