Animate CC HTML5 Canvas subscript

[ThirstyOctopus]

Hi, 

I put together an interactive HTML5 canvas document. 

After a week of fighting multiple snags and learning curves, I finally have a working product! Just when I thought I was done, I am stumped once more after I received the content to update the text with. 

I am trying to put the word CO2 in there, but I need the 2 to be subscript.

var string1 = "how much CO";
var string2 = "2";
var substring = string2.sup();
var string3 = " is used?";

_this.inst_text.text = string1 + substring + string3;

It shows up as,

"How many ₂ is used."

I need to stick with Dynamic text because I change it out later in code. 

Any suggestions?

Thanks!

Hi.

You can use unicodes and the static method fromCharCode from the String class. Like this:

var root = this;

root.charfromUnicode = function(code)
{
	return String.fromCharCode(parseInt(code, 16));
};

console.log("CO" + root.charfromUnicode(2082));

I hope this helps.
