Creating the first structure

1. To create it, you will need a construction schematic.

2. Recommendations for the schematic

   1. Place the main point in the center of the building.

   2. Build a foundation for your schematics so that your buildings don't float in the air. An example of the foundation is below.

   3. 
   4. You can create any schematic, any size. There are no restrictions.

3. Mobs

   1. To spawn vanilla mobs, use their ID directly in the schematic.

   2. 

   3. If you use MythicMobs, then write [mythicmobs]ID, if it doesn’t fit, then move it to other lines, as shown in the screenshot below.

   4. 

4. Create a configuration file in the same folder with the same name as the schematic. If the schematic is named test.schem, the configuration file should be named test.yml.

5. Configure the .yml file as described below.

Key	Description	Values / Examples
biomes	Accepts many biome values.	minecraft:mushroom_fields minemagic:astral_mushrooms ...
WhiteListBlocks	On which block is the schematic allowed to appear.	GRASS_BLOCK MOSS_BLOCK ...
threshold	The lower this value, the more often your building will be generated.	Takes values ​​from 0 to 1
scale	The second value is for the noise generator. I recommend setting it to 0.6.
distance	At what distance from each other will the structures appear. Counted in blocks	I recommend avoiding placing multiple buildings in a single biome within 5 blocks of each other. This may impact server TPS.
world	The world in which structures will be generated. Takes one value.	world world_the_end ...
seed	Specify the seed for noise	90813958915
surface	A value of true will generate structures on the ground. A value of false will create them in the air or underground.	true false
offsetX	Offsets a building by a certain number of blocks in X direction. Useful for using multiple identical buildings so they don't spawn in the same place. If you don't need to use it, delete the line.	-10
offsetZ	Offsets a building by a certain number of blocks in Z direction. Useful for using multiple identical buildings so they don't spawn in the same place. If you don't need to use it, delete the line.	30
minY	Used if surface is false. The structure will not appear below this point. If you don't need to use it, delete the line.	200
maxY	Used if surface is false. The structure will not appear above this point. If you don't need to use it, delete the line.	250
height	Structure insertion priority. Structures with a higher priority will be inserted first.	10
lootTableKey	Specify the loottable ID. All containers in your structure will use the loot from it.	minecraft:chests/jungle_temple_dispenser
