Another fun addition allows the player to create custom NPCs that interact with other players. They can talk, etc., and really add life to a build. Here's a link to one such program: https://everysingleminecraftmodthatendsuponhere.fandom.com/wiki/Custom_NPCs#:~:text=Custom%20NPCs%20is%20a%20mod%20that%20allows%20you,servers%20with%20characters%20that%20can%20be%20interacted%20with.
I've used these on survival servers. They really add life to a build and greatly enhance the options available for decorating. Here's a link to one such program: https://www.planetminecraft.com/data-pack/armor-stand-customizer-v2-0-1-14/
Some survival servers that I've played on have the command /hdb. It allows the players to add small, custom blocks as decorations to their builds. I think the custom 'mini-blocks' really add to the decorative options available when building. Here is a link to a page showing a few of the many blocks available. I've seen this plugin available for versions as recent as 1.15.2. https://www.planetminecraft.com/project/18-custom-head-database-300-heads-/
I want to make a build that uses red & white tulips. Could those be added to the /shop? Thanks :)
