please implement all redstone mechanisms such as hopper, repeaters, pistons, etc. I use them for my skyblock server please. And if you could also implement the animals and monsters, it would be fine if you can not do this with the redstone mechanisms.
And while you're at it, create word peace, establish communism, stop climate change and inflate flat earth.
Sorry, but that can't be done instantly... that can't even be done in a year. I've said this before, but like any good programmers, the PMMP developers are focusing on fixes and stability, before adding features. The official Bedrock server software has all of those things, but the lack of modding or plugins would make creating a SkyBlock server difficult; if not impossible. There have been plugins for PocketMine that implement mobs and others that implement most of the Redstone mechanics however.
