1,在一些项目里面可能要缓存图片,这样有助于面板的快速的展现:
如是,就出现了2中情况:
①:刚开始加载游戏时,就顺带着去分布式加载图片(所有重要的)
②:在需要的时候加载,并存入缓存,下次需要时,直接读缓存
这2种方案都有利弊:
第一种,会拖延加载进度,可能会导致内存,性能的损耗
第二种,第一次加载时,面板的显示速度慢
我现在的方案是:
2种方式看玩家信息情况决定:
图片加载管理器类:

如,玩家有任务需要领取,(刚刚进入游戏时,请求后端是)顺带要请求ICONs
var $modelsV : Vector.<String> = new Vector.<String>();
for(var i : String in _tasksInitData){
$modelsV.push(i);
}
TasksItemsIconsManager.instance.initData($modelsV);当然:
/**

private function loadTaskIconKayer($iconPath : String = "" ) : void{
if(!$iconPath){
MJDebugger.info("---- ----任务图标路经错误",$iconPath);
}
TasksItemsIconsManager.instance.getIconByPath($iconPath,callBack);
}
/**

private function callBack($obj : * ,$path : String = "") : void{
if($obj is Bitmap){
var $bm : Bitmap = $obj as Bitmap;
this.addChild($bm);

}else{
if($obj is Loader){

$myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,__onLoaded,false,0,true);

$myLoader.load(new URLRequest($path),new LoaderContext(true));
}
}
}

if ($myLoaderInfo != null && $myLoaderInfo.loader != null && $myLoaderInfo.loader.content && $myLoaderInfo.loader.content is Bitmap) {
var $bm : Bitmap = $myLoaderInfo.loader.content as Bitmap;
if($bm != null){
var $bufferIcon : TasksItemsIconsDataModel = new TasksItemsIconsDataModel();
$bufferIcon.iconPath = LoadingBiz.CLIENTURL+"res/task/"+taskSerial+".png";
Debug.log("31115.1+URL+:=>"+$bufferIcon.iconPath);
$bufferIcon.iconBitMap = $bm;
TasksItemsIconsManager.instance.addNewModel($bufferIcon);
Debug.log("31115.1---自我ICON");
this.addChild($bm);
$bm.x = 10;
$bm.y = 7;
}
$myLoaderInfo.loader.unload();
}
}
private function __onLoadingError( $e : IOErrorEvent ) : void{
Debug.log("加载资源出错 ICON --- 31115.1");
}这样下次去图片时,直接取内存
