Instant structures are here! Currently instant structures part 1 is available. Crafting for the spawn eggs will soon be available as a separate command. More coming soon! Go to https://www.youtube.com/watch?v=KHVRcYbuqLI to watch a video on how to set up a one command creation. I do not take credit for making the video. All credit goes to LyricLy(https://www.youtube.com/channel/UCFWGugKm2ONRl1sUUUJw6Tg) for the video. Crafting recipes are within the same part as the part your looking for.
