Install & configure
Windows and Linux, PHP binaries, server.properties and every pocketmine.yml setting.
Install VanillaMine, configure worlds and mobs, put VanillaGate in front of your network, and write plugins with an API that still runs every PocketMine-MP 5 plugin.

The first VanillaMine release adds a proxy API and a Paper-style mob API for plugins:
$net = $this->getServer()->getProxyNetwork();
$net?->transfer($player, "survival", ProxyNetwork::STYLE_SEAMLESS);See Proxy networks, Mob spawning & AI and the full list of additions.
