How to display Movie Clip if shared Object is equal to a number AS3

问题

Hey everyone so what I've been trying ti accomplish with no success is how to display my Movie Clip object named achiev_10 when the nScore which is a number equal to 10.

Here is what I have so far in my Shared Object Data.

In my Constructor I have this:

//Initialize our shared object give it a path to save local data
        sharedObject = SharedObject.getLocal("GeometryBlast");

         if (sharedObject.data.highScore == null)
         {     
               // checks if there is save data
               trace("No saved data yet."); // if there isn't any data on the computer...
               sharedObject.data.highScore = nScore; // ...set the savedScore to 0
         } else 
         {
               trace("Save data found."); // if we did find data...
               loadData(); // ...load the data
         }

Then in the saveData(); function I have this:

public function saveData():void
    {
        if (nScore > sharedObject.data.highScore )
        {
            sharedObject.data.highScore = nScore;

        }
        menuEnd.bestScore.text = " " + sharedObject.data.highScore;
        sharedObject.flush();
        //trace("Data Saved!");
        //sharedObject.clear();

        if (nScore == 10)
        {
            achiev_10 = new Achievment_10();
            menuEnd.addChild(achiev_10);
            achiev_10.x = stage.stageWidth / 2;
            achiev_10.y = stage.stageHeight / 2;
            sharedObject.flush();
        }

    }

Now currently in the if (nScore == 10) where I add the Move Clip, it does work and it does display. But when i go back to check my Move Clip achievement it dissapears. I don't really know what i need to do to save the data if the save data.highscore is equal to 10 then always display that achievement.

I also tried this but nothing:

 if (sharedObject.data.highScore == 10)
    {
        achiev_10 = new Achievment_10();
        menuEnd.addChild(achiev_10);
        achiev_10.x = stage.stageWidth / 2;
        achiev_10.y = stage.stageHeight / 2;
        sharedObject.flush();
    }

please help thank you!

You will need several functions to work with SharedObject. But you should know, user can clear values from the SharedObject, and achievements will be lost.

private function getScore(key:String, domain:String):* {
    try {
        var so:SharedObject = SharedObject.getLocal(domain);
        var data:Object = so.data;

        if (key in data) {
            return data[key];
        } else {
            trace(key + " doesn't present in SharedObject");
        }

    } catch (e:*) {
        trace("Oops, something goes wrong…");
    }
}

private function saveScore(value:*, key:String, domain:String):void {
    try {
        var so:SharedObject = SharedObject.getLocal(domain);
        so.data[key] = value;
        so.flush();
    } catch (e:*) {
        trace("Oops, something goes wrong…");
    }
}

Now you can work with scores:

var domain:String = "GeometryBlast";
var scoreKey:String = "ScoreKey";
const newcomer: int = 10;

//Getting scores
var myScore: Number = getScore(scoreKey, domain);

//Simple example how you could manage score values
if(!isNaN(myScore)){
    //Check achievements

    if(myScore >= newcomer){
        //Add 'Newcomer' achievement to the screen
    }
}

//Saving scores
var someScores:Number = 10;
saveScore(someScores, scoreKey, domain);
