Help with Server Side Highscores Script on Wiki

Hi,

I get this error:

Assets/Scripts/HSController.js(16,32): BCE0051: Operator ‘+’ cannot be used with a left hand side of type ‘Object’ and a right hand side of type ‘Object’.

at var hash = Md5.Md5Sum(name + score + secretKey);

in HSController.js

I don’t get why I’m getting this error when its a string…

Can anyone Help?

just a hunch… passing the object to postScore instead of the object’s name as a string?

Make sure all of the objects in the MD5 hash are casted to strings. You can force it by this:

var hash = Md5.Md5Sum(name + (“” + score) + secretKey);

or

var sScore : String = “” + score;
var hash = Md5.Md5Sum(name + sScore + secretKey);

I assume name and secretKey are already strings.

Thx Martin that fix the error but no scores show up… The GUI show “Loading Score” then nothing appears. This is what I have.

function Start() {
	postScore(iPhoneSettings.name , 100);
    getScores();
}

function postScore(name, score) {
    //This connects to a server side php script that will add the name and score to a MySQL DB.
    // Supply it with a string representing the players name and the players score.
    var hash = Md5.Md5Sum(name + ("" + score) + secretKey); 

    var highscore_url = addScoreUrl + "name=" + WWW.EscapeURL(name) + "&score=" + score + "&hash=" + hash;
       
    // Post the URL to the site and create a download object to get the result.
    var hs_post : WWW = new WWW (highscoreUrl);
    yield hs_post; // Wait until the download is done
    if(hs_post.error) {
        print("There was an error posting the high score: " + hs_post.error);
    }
}
 
// Get the scores from the MySQL DB to display in a GUIText.
function getScores() {
    guiGameObj.text = "Loading Scores";
    var hs_get : WWW = new WWW (highscoreUrl);
    yield hs_get;
   
    if(hs_get.error) {
        print("There was an error getting the high score: " + hs_get.error);
    } else {
       guiGameObj.text = hs_get.data; // this is a GUIText that will display the scores in game.
    }
}

Any ideas why its not showing up?
