The Building configuration is the region configuration from HeroStronghold.

There are several parts of the configuration:

• friendly-classes: [] , not used in realms
• enemy-classes: [] , not used in realms
• effects: , list of effectname for area protection. Dont change this list until you understand the effect.
• radius: , define the building area with a formula. the area is CUBE. All axis of have the same length. In the center must be a AIR block. The edge formula is 👍

edge_of_the_cube = (radius * 2) -1

example: radius = 4 , edge = 7 (4 * 2) -1

• requirements [] , list of items or block that required for create. The items or blocks must elsewhere in the building area present. Only the number will check, not the position.
• reagents [] , list of items or block that required after create. The items or blocks must give to the center chest for proper function of the building. Like protection and production. The center chest will automaticly generated.
• upkeep: [] , list of items or block that required for upkeep. This is the consume list.

• biome: [] , a list of biomenames in that the building can created. If the list is not empty only in this biomes can be created.
• description: hmmm... what can this mean ?

remark: Because there is an error in Herostronghold, every building need a free block around the defined building area. so a R4 = 7x7 needs area of 9x9 to build without overlapping with nearby buildings.
