/AS3/ RPG - Discount numbers to Variables

var str:int = 1;
var hp:int = 15;
texthp.text = hp.toString(); //i have a dynamic text with an instance name of “texthp”

attack.addEventListener(MouseEvent.CLICK, playerattack);

function playerattack(Event:MouseEvent):void{
hp – str;
}

i want discount str to hp but this code doesn’t work.

it’s not hp - str, it’s hp -= str.

still doesn’t work

Are you updating texthp to the new value of hp?

The hp variable is indeed going down (you could trace it to verify), but you’re not updating the text field to display the change.

The variable is never modified, as the assignment operator isn’t being used.
Tracing hp will return 15.

I meant it’s going down with clasher235’s solution.

here is the final code:

function playerattack(Event:MouseEvent):void{
hp -= str;
texthp.text = hp.toString(); // after doing hp -= str, refresh the text.
}

Thanks for your help!!

Just remember that int and String are primitive types in AS3 and so have their data copied; not their reference

On the other hand, if they were referenced, you wouldn’t get logical output when doing myText.text = myVar (you’d get a pointer value!)
