Welcome to Schematic Importer! This mod's premise is simple, get your Minecraft builds into Hytale by simply:

Putting this Jar file in your mods folder (...\Roaming\Hytale\UserData\Mods) (for running it yourself)

NOTE: Hytale currently has a feature where new mods get auto-disabled when you load them on a world for the first time. If the mod isn't loading, go into the world settings (right click) and enable the mod.

Use /hsi schematic to open the schematic import menu. Close it again, and the mod will tell you the directory to place files in using a chat message (...\Mods\thirtyvirus_SchematicImporter\schematics) (for running it yourself)
Put .litematic or .schem files in the correct directory
From there, you may use "/hsi schematic" again and select your schematic
Once in the Map Schamatic Block screen, one-by-one you are able to pick Hytale blocks to map to the Minecraft ones from your schematic by clicking on them. There's a convenient block selection menu with filters and multiple sorting methods, a search bar, and multi-page results for better performance.
Once you've replaced as many blocks as you wanted, or disabled them, or left them to be filled in by the default block, you may click "Paste Schematic". Additionally, you can do a test paste that's only the default block, for debug purposes.

And most importantly, if you enjoy using this mod please use Creator Code "ThirtyVirus" in the Hytale Store!
