Problem with local storage

Hi guys,
i have a problem with local storage. Here is my two codes :
the fisrt one to save the data seems ok (last line):

addScore(){
this.gameScore ++;
this.scoreLabel.string = 'Score : ’ + this.gameScore.toString();
cc.sys.localStorage.setItem(“myScore”, ‘this.gameScore’);
}

but the second to retrieve the value is not… :

var myItem = localStorage.getItem(“myScore”);

Those are in two scenes different but the problem with the second code is that it don’t accept the “var”.
I’m using typeScript.

I need help please :slight_smile:

shouldn’t the line to retrieve the score be like this?

var myItem = cc.sys.localStorage.getItem(“myScore”);

Thanks! now it works… partially

updateScore(){

    this.myscore = cc.sys.localStorage.getItem('myScore');
    var myItem = cc.sys.localStorage.getItem('myScore');
    this.scoreLabel.string = 'Score : ' + myItem.toString();
}

I made those lines in a function but how can i call it now ? because if i type updateScore() beneath it does not works

You need to call it from onLoad or whenever you want to show your score on the screen.

For example you can make a score screen and put this component on it. Call updateScore() in components onEnable function. This way it’ll update label when you show the scrore screen.
