What is "toString"?

[Guest]

So I have this piece of code which allows for a score to be displayed in my game

var plScore:int = 0;

         score_txt.text = plScore.toString();

It then updates by 1 when the player collects an item

plScore +=1;

     score_txt.text = plScore.toString();

It works fine however I want to know what "toString()" is and how it works in the context of this set of code as all I really know is that it allows for the numbers to be displayed as text in the level but I am unsure how it does it.

it's just converting file type from (in your code, an int to a string).  casting does the same:

var plScore:int=0;

score_txt.text=String(plScore);

Ah ok thanks. Could you please briefly explain how "string" works int the context of this code, like how does it allow for the numbers to be displayed as text?

i don't understand what you are asking but maybe this will help.

you could try:

score_txt.text = plScore;

and read the ensuing error message.  perhaps that will help you understand why casting or using toString is needed.

or you may have a more profound question about why adobe engineers/developers chose to have textfields display strings only.  or maybe you don't understand 'typing' and need some help with a more basic understanding of programming principles.  like i stated in the first sentence, i don't understand what you're asking.
