Execute command, _(*6)

composer require a1essandro/perlin-noise ~1.0

Usage

$generator = new MapGenerator\PerlinNoiseGenerator();
$generator->setSize(100); //heightmap size: 100x100
$generator->setPersistence(0.8); //map roughness
$generator->setMapSeed('value'); //optional
$map = $generator->generate();

or

$generator = new MapGenerator\PerlinNoiseGenerator();
$map = $generator->generate([
    PerlinNoiseGenerator::SIZE => 100,
    PerlinNoiseGenerator::PERSISTENCE => 0.8,
    PerlinNoiseGenerator::MAP_SEED => 'value'
]);

mixed:

$generator = new MapGenerator\PerlinNoiseGenerator();
$generator->setSize(100);
$map = $generator->generate([
    PerlinNoiseGenerator::PERSISTENCE => 0.8
]);
