Not long ago @aliyuli created the empty world generator. I also have to create a generator for my plugin. Can you give me some basics how to create a custom generator? For example, i will have a small structure and this structure will repeat after some blocks.. Is that even possible? What parameters does the generators class have? Thanks in advance, Dan
btw look into Flat.php under Level->Generator PHP: <?php/*** ____ _ _ __ __ _ __ __ ____ * | _ \ ___ ___| | _____| |_| \/ (_)_ __ ___ | \/ | _ \* | |_) / _ \ / __| |/ / _ \ __| |\/| | | '_ \ / _ \_____| |\/| | |_) |* | __/ (_) | (__| < __/ |_| | | | | | | | __/_____| | | | __/* |_| \___/ \___|_|\_\___|\__|_| |_|_|_| |_|\___| |_| |_|_|** This program is free software: you can redistribute it and/or modify* it under the terms of the GNU Lesser General Public License as published by* the Free Software Foundation, either version 3 of the License, or* (at your option) any later version.** @author PocketMine Team* @link http://www.pocketmine.net/***/namespace pocketmine\level\generator;use pocketmine\block\CoalOre;use pocketmine\block\DiamondOre;use pocketmine\block\Dirt;use pocketmine\block\GoldOre;use pocketmine\block\Gravel;use pocketmine\block\IronOre;use pocketmine\block\LapisOre;use pocketmine\block\RedstoneOre;use pocketmine\item\Item;use pocketmine\level\ChunkManager;use pocketmine\level\format\FullChunk;use pocketmine\level\generator\biome\Biome;use pocketmine\level\generator\populator\Ore;use pocketmine\level\generator\populator\Populator;use pocketmine\math\Vector3;use pocketmine\utils\Random;class Flat extends Generator{ /** @var ChunkManager */ private $level; /** @var FullChunk */ private $chunk; /** @var Random */ private $random; /** @var Populator[] */ private $populators = []; private $structure, $chunks, $options, $floorLevel, $preset; public function getSettings(){ return $this->options; } public function getName(){ return "flat"; } public function __construct(array $options = []){ $this->preset = "2;7,2x3,2;1;"; //$this->preset = "2;7,59x1,3x3,2;1;spawn(radius=10 block=89),decoration(treecount=80 grasscount=45)"; $this->options = $options; $this->chunk = null; if(isset($this->options["decoration"])){ $ores = new Ore(); $ores->setOreTypes([ new object\OreType(new CoalOre(), 20, 16, 0, 128), new object\OreType(New IronOre(), 20, 8, 0, 64), new object\OreType(new RedstoneOre(), 8, 7, 0, 16), new object\OreType(new LapisOre(), 1, 6, 0, 32), new object\OreType(new GoldOre(), 2, 8, 0, 32), new object\OreType(new DiamondOre(), 1, 7, 0, 16), new object\OreType(new Dirt(), 20, 32, 0, 128), new object\OreType(new Gravel(), 10, 16, 0, 128), ]); $this->populators[] = $ores; } /*if(isset($this->options["mineshaft"])){ $this->populators[] = new MineshaftPopulator(isset($this->options["mineshaft"]["chance"]) ?

Now, after a while looking into the code i understand what the generator does. I'll try to rewrite the generator to support what i want. Thanks
