U3D的一些常用基础脚本

修改渲染颜色和贴图

   1: var texture :Texture ;

   2:  

   3: function Start () {

   4:     renderer.material.mainTexture = texture ;

   5:     renderer.material.color = Color.green ;

   6: }

遍历并删除孩子节点 

   1: function Start () {

   2:     var count :int = transform.childCount ;

   3:     for( var i=0; i<count; i++ ) {

   4:         var child :Transform = transform.GetChild( i );

   5:         GameObject.Destroy( child.gameObject );

   6:     }

   7: }

创建预设的游戏对象并在5秒后销毁

   1: var prefab :GameObject ;

   2: var pos :Vector3 ;

   3: var rot :Quaternion ;

   4:  

   5: function Start () {

   6:     var clone :GameObject = GameObject.Instantiate( prefab )  ; //此处不加位置旋转参数，则会使用预设的参数值

   7:     

   8:     var clone2 :GameObject = GameObject.Instantiate( prefab, pos, rot ) ;

   9:     

  10:     GameObject.Destroy( clone, 5 );

  11: }

具有父子关系的游戏对象间消息的传递

function SendMessage (methodName : String, value : object = null, options : SendMessageOptions = SendMessageOptions.RequireReceiver) : void

发消息给自己，一般是由其它的组件来获取消息并处理它；如果options不传，则可以不接收；如果options参数为requireReceiver且游戏对象没有该处理方法，则或报错！

function BroadcastMessage (methodName : String, parameter : object = null, options : SendMessageOptions = SendMessageOptions.RequireReceiver) : void

广播消息给自己及孩子节点，孩子节点递归；只要注册有MethodName处理方法，都会接收到该消息并触发；

function SendMessageUpwards (methodName : String, value : object = null, options : SendMessageOptions = SendMessageOptions.RequireReceiver) : void

广播消息给自己及父级节点，父级节点递归；只要注册有MethodName处理方法，都会接收到该消息并触发；

之所以把这几个消息特意拎出来，是因为之前不知道这个的时候，消息都是先获取到游戏对象的指定组件，再调用指定组件的指定方法，现在看来觉得这种方式有点傻！

U3D与Web间的通信

   1: function Start () {

   2:     Application.ExternalCall( "jsFunctionToBeCalledByUnity", "paramString" ) ;

   3: }

   4:  

   5: function UnityFunctionToBeCalledByJs( param :String ){

   6:     Debug.Log( "Function is Called By JS , param : " + param ) ;

   7:     Application.ExternalEval( " alert( 'msg' ) ; " );

   8: }

   9:  

  10: //WEB页面的JS

  11: function jsFunctionToBeCalledByUnity( param ) {

  12:     u.getUnity().SendMessage("MyObject", "UnityFunctionToBeCalledByJs", "Hello from a web page!");

  13: }
