I have noticed that there is no developer willing to take their time to add back redstone, so I will do it. But I noticed a few things are missing, mainly the blocks and textures, but I will be coding their functionality for whenever they are added, or if people help provide to add them in.
Um in case you didn't know, pocketmine doesn't make or send any textures aside from resource packs. Minecraft already has the textures, so there's no need.
Oh, yea i noticed all the textures may be there, just unused. Currently working on getting redstone wire and torch working.
There is already an existent PMMP plugin that implements redstone. It uses a nukkit source, and is called "RedstoneCircuit". It can be found on github or in poggit dev builds. Just saying, in case you didn't know.
Don't you think if it was so easy to fix them they would of been implemented by now? It's not like they are not implementing them because they don't want us to have more in-game features.
Softwares aren't light bulbs. If some software doesn't work, you don't get it fixed by replacing it with something new.
