# TownChest
A minetest mod contains a chest with building definitions. The chest can spawn a NPC that does build the building for you.
The mod uses the schemlib framework to handle the buildings

Minetest Schematic File Format
All values are stored in big-endian byte order.

[u16] size Y
[u16] size Z
For each Y:

For each node in schematic:

Version changes:
1 - Initial version
2 - Fixed messy never/always place; 0 probability is now never, 0xFF is always
