Hi. I have this table:

Schema::create('maps', function($table) {
		$table->engine = 'InnoDB';
		$table->increments('id');
		$table->string('name');
		$table->integer('coord_x');
		$table->integer('coord_y');
		$table->integer('coord_z');
		$table->unique(['coord_x', 'coord_y', 'coord_z']);
		$table->timestamps();
	});

And I want to validate the uniqueness of the 3 coords. For now I have this:

public static $rules = [
    'name' => ['required', 'between:3,29', 'unique:maps'],
    'coord_x' => ['required', 'integer'],
    'coord_y' => ['required', 'integer'],
    'coord_z' => ['required', 'integer']
];

Thanks
