[AS3] High score system with a dynamic text field

[loewenstern]

Hey there. I'm stuck. This was quite easy in AS 2, but I can't seem to figure out how to solve it in AS 3.

I want to make a high score system. Everytime "helten" hits "smilefjes" I want the text field called "hiscore" that starts with 0 to go 10 points up. My first attempt was the following:

addEventListener(Event.ENTER_FRAME, onLoop, false, 0, true);
function onLoop(evt:Event):void {
	if (helten.hitTestObject(smilefjes)) {
	  hiscore.text += 10;
    }
}

What happens when I run this is that the text field just adds a zero next to the zero that already is there.

I have 2 questions. First, why doesn't it add the 10 instead of just a zero? Second, how can I make it work so that the 0 is replaced with the 10 when "helten" hits "smilefjes", and the second time the 10 is replaced with 20 etc.

I am no professional in as3 but I like helping people so I did some googling and found something. First of all, try adding

var hiscore:int=0;
hiscore.text=String(hiscore);

to the top of your code, then change

hiscore.text += 10;

to

hiscore+=10;

I purposely didn't put any spaces in the new piece of code, cause thats how I found it. I have to give credit to this thread: actionscript.org/forums/showthread.php3?t=234059 Hope I helped.

Thanks, you are gentleman and a scholar. It didn't work as it was, but when I edited it a bit it worked.

var highscore:int=0;

addEventListener(Event.ENTER_FRAME, onLoop, false, 0, true);
function onLoop(evt:Event):void {
	if (helten.hitTestObject(smilefjes)) {
	  highscore+=10;
	  hiscore.text = String(highscore);
	}
}

was what I ended up with. If you see in the thread you linked you can see that "myScore" and "myScore_txt" is not the same. "myScore" is the name of the textfield while "myScore" is just the name of the variable.

My textfield is called hiscore and my variable is called highscore.

Hi fellow Norwegian,

it only added it at the end of the textfield, because a textfield is a String, it's not a Number, hence it doesn't have any mathematical function, such as adding and subtracting. Declaring an integer variable and incrementing it, and displaying that variable in your textfield, is indeed the correct way of doing it. Also, I am assuming you typed 0 in your dynamic textfield, like manually, right? Because, that's why it was only adding 0 at the end and not 10, because you haven't embedded the font to your dynamic textfield, making it only display the font characters already typed in the textfield!
