NAME

Graphics::Raylib - Perlish wrapper for Raylib videogame library

VERSION

version 0.019

SYNOPSIS

use Graphics::Raylib;
use Graphics::Raylib::Text;
use Graphics::Raylib::Color ':all';

my $g = Graphics::Raylib->window(120,20);
$g->fps(5);

my $text = Graphics::Raylib::Text->new(
    text => 'Hello World!',
    color => DARKGRAY,
    size => 20,
);

while (!$g->exiting) {
    Graphics::Raylib::draw {
        $g->clear;

        $text->draw;
    };
}

raylib

raylib is highly inspired by Borland BGI graphics lib and by XNA framework. Allegro and SDL have also been analyzed for reference.

NOTE for ADVENTURERS: raylib is a programming library to learn videogames programming; no fancy interface, no visual helpers, no auto-debugging... just coding in the most pure spartan-programmers way. Are you ready to learn? Jump to code examples or games!

IMPLEMENTATION

This is a Perlish wrapper around Graphics::Raylib::XS, but not yet feature complete. You can import Graphics::Raylib::XS for any functions not yet exposed perlishly. Check out the examples/ directory for examples on how to do so.

TESTING

If you want to skip graphical tests when installing, define NO_GRAPHICAL_TEST in the environment. These tests are also skipped automatically if no graphic device is available.

AUTOMATIC IMPORT

use Graphics::Raylib '+family'; can be used as a shorthand for

use Graphics::Raylib::Color ':all';
use Graphics::Raylib::Shape;
use Graphics::Raylib::Texture;
use Graphics::Raylib::Text;
use Graphics::Raylib::Mouse;
use Graphics::Raylib::Keyboard ':all';

METHODS/SUBS AND ARGUMENTS

window($width, $height, [$title = $0])

Constructs the Graphics::Raylib window. $title is optional and defaults to $0. Resources allocated for the window are freed when the handle returned by window goes out of scope.

If no graphic device is available it returns an undef value.

fps($fps)

If $fps is supplied, sets the frame rate to that value. Returns the frame rate in both cases.

clear($color)

Clears the background to $color. $color defaults to Graphics::Raylib::Color::RAYWHITE.

exiting()

Returns true if user attempted exit.

draw($coderef)

Begins drawing, calls $coderef->() and ends drawing. See examples.

draw3D($coderef)

Begins 3D drawing, calls $coderef-()> and ends drawing. See examples.

EXAMPLES

Conway's Game of Life

my $HZ = 120;
my $SIZE = 160;
###########

my $CELL_SIZE = 3;

use Graphics::Raylib '+family'; # one use to rule them all
# Alternatively
use Graphics::Raylib::Color ':all';
use Graphics::Raylib::Shape;
use Graphics::Raylib::Text;

use PDL;
use PDL::Matrix;

sub rotations { ($_->rotate(-1), $_, $_->rotate(1)) }

my @data;
foreach (0..$SIZE) {
    my @row;
    push @row, !!int(rand(2)) foreach 0..$SIZE;
    push @data, \@row;
}

my $gen = mpdl \@data;

my $g = Graphics::Raylib->window($CELL_SIZE*$SIZE, $CELL_SIZE*$SIZE);

$g->fps($HZ);

my $text = Graphics::Raylib::Text->new(color => RED, size => 20);

my $img = Graphics::Raylib::Texture->new(
    matrix => unpdl($gen),
    fullscreen => 1,
    # color => GOLD # commented-out, we are doing it fancy
);

my $rainbow = Graphics::Raylib::Color::rainbow(colors => 240);

while (!$g->exiting) {
    $img->matrix = unpdl($gen);
    $img->color = $rainbow->();
    $text->text = "Generation " . ($i++);

    $g->clear(BLACK);

    Graphics::Raylib::draw {
        $img->draw;
        $text->draw;
    };


    # replace every cell with a count of neighbours
    my $neighbourhood = zeroes $gen->dims;
    $neighbourhood += $_ for map { rotations } map {$_->transpose}
                             map { rotations }      $gen->transpose;

    #  next gen are live cells with three neighbours or any with two
    my $next = $gen & ($neighbourhood == 4) | ($neighbourhood == 3);

    # procreate
    $gen = $next;
}
