About

The general purpose personal libs I use in all my Haxe projects.

Install

Stable

Use this version if you plan to use the libs for your own projects.

haxelib install deepnightLibs

Latest Git version (mostly stable)

Use this version if you're building one of my own projects, such as LDtk or one of my gamejam entry.

haxelib git deepnightLibs https://github.com/deepnight/deepnightLibs

Usage

In your HXML file, add:

-lib deepnightLibs

All the libs are in the dn.* package.

class MyProject {
	public function new() {
		trace( dn.Color.intToHex(0) ); // "#000000"
	}
}

Tips

Use global imports! To import libs in every HX files, just add a import.hx (this exact name & caps) file to the root of your src folder:

dn.*;
dn.Color as C;

• The first line imports all classes in dn package,

• The second one imports Color as an alias "C",

• Feel free to add your own convenient imports there.

Noteworthy classes

dn.M

My re-implementation of the Math class, with high-performances in mind:

M.fmin(0.5, 0.9); // 0.5
M.frandRange(0, 2); // random Float number between 0 -> 2
M.randRange(0, 2); // either 0, 1 or 2
M.pow(val, 2); // turns into val*val at compilation time

dn.Color

The color management lib.

It mostly works using UInt colors (0xRRGGBB, like 0xffcc00), but contains many useful methods to convert color to various formats (HSL, ARGB, String).

dn.Color.intToHex(0); // #000000
dn.Color.toWhite(0xff0000, 0.5); // Interpolates color to white at 50%
dn.Color.getPerceivedLuminosityInt(0x7799ff); // return perceived luminosity (0 to 1.0)

dn.DecisionHelper

A nice tool to easily pick a value among many others using any custom criterion.

var arr = [ "a", "foo", "bar", "food", "hello" ];

var dh = new dn.DecisionHelper(arr);

/* Iterates all values in arr and increase their internal score by 1 if they contain the letter "o". */
dh.score( v -> StringTools.contains(v,"o") ? 1 : 0 );

/* Increase score of each values using 10% of their length (ie. longer strings get slightly higher score) */
dh.score( v -> v.length*0.1 );

/* Discard any value containing the letter "h" */
dh.remove( v -> StringTools.contains(v,"h") );

/* Only keep values with length>1 */
dh.keepOnly( v -> v.length>1 );

trace( dh.getBest() ); // -> food
/* Internal scores: a (discarded), foo (1.3), bar (0.3), food (1.4), hello (discarded). */
