该类是对于同平面物体
深度简单自动管理类
只是做到了简单虚拟社区等人物建筑物等深度排列太复杂估计就搞不定了但是可以继承这个类继续定义index.com.
.Leval2D类:代码:public
Level2D implements IEventDispatcher现实:IEventDispatcher接口
对同
容器中物体以Y坐标为基准进行自动深度管理构造
:public function Level2D(range_:DisplayObjectContainer)
参数表示要对哪个容器中
对象进行自动深度管理手动排列深度 思路方法:
public function re
:Array返回排列后
对象
如果层级无改变则返回当前对象层级改变将调度事件Level2DEvent.LEVEL_RESET
获取对象列表 思路方法:
public function getDisplay(arg:Object = null):Array
获取当前管理容器中
以arg方式过滤后所有对象若arg为空
则返回当前容器中所有对象列表若arg为
串则返回当前容器中所有对象arg属性列表若arg为Object
则返回当前容器中符合arg所有属性对象列表遍历 思路方法:
public function forEach(fun:Function,arg:Object = null):void
以某种方式遍历所有对象
并且有arg方式进行过滤遍历第
个参数在遍历时候每遍历到个对象都会
fun将显示对象和排列位置传出去例如:function callback(_display:DisplayObject,index:
){}第 2个参数
等同于getDisplay中arg参数私有继承思路方法:
protected function inOrder(tmpAr:Array):void
以某种特定
进行深度改变该思路方法必须继承该类
它子集便可以当作私有属性来该思路方法外部不可见！设置即时属性:(只写)
public function
isTime(_isTime:Boolean):void当参数为true
则表示层级在可以改变时候会自动进行改变当参数为false
则表示需要手动re思路方法才能改变深度排列range属性:(只读)
public function get range
:DisplayObjectContainer当例子化管理容器后
就无法修改该属性了只有通过range来读取属性了举例:
