Added letterSpacing variable to FlxText.

[MAJigsaw77]

Adds access to openfl's letterSpacing in FlxText instances.

related issue, letterSpacing doesn't work on html5 - openfl/openfl#1700

nice

[Geokureli]

See below for requested changes and provide a small use case

[Geokureli]

1. (default, set) will cause issues, since set_ letterSpacing only sets _defaultFormat.letterSpacing. meaning the following will happen:

text.letterSpacing = 1;
trace(text.letterSpacing); // null

We should add a getter that returns _defaultFormat.letterSpacing

2. looks like the other fields avoid using Null and just use primitive types, I think Null should be avoided if possible. let's use Float and set the default value to 0, and also set the _defaultFormats initial letterSpacing to 0

[MAJigsaw77]

The letterSpace is null by default in openfl

[MAJigsaw77]

That value cannot be getted

That value cannot be getted

Sure it can

The letterSpace is null by default in openfl

I understand, that's why i said "set the _defaultFormats initial letterSpacing to 0", specifically, here

[Geokureli]

also this is gonna wait until after the 5.6.1 release, which should happen soon

[Geokureli]

To reiterate:

set the _defaultFormats initial letterSpacing to 0
specifically here

Also:

provide a small use case

[MAJigsaw77]

Usage example:

import flixel.text.FlxText;

var text:FlxText = new FlxText(0, 0, 0, "Hello World", 64);
text.letterSpacing = 2.5;
text.screenCenter();
add(text);

[Geokureli]

All good, I'll merge this after I get 5.6.1 released

[Geokureli]

When i test the following code:

var text1 = new FlxText(0, 0, 0, "Hello World", 64);
text1.screenCenter();
text1.y -= text1.height / 2;
add(text1);

var text2 = new FlxText(0, 0, 0, "Hello World", 64);
text2.letterSpacing = 10;
text2.screenCenter();
text2.y += text2.height / 2;
add(text2);

I get this result, that seems like 2 identical results, despite different values for letterSpacing

This is an openfl issue on html5, I linked the issue in the description
