Minetest Schematic File Format
|
|
|
|
All values are stored in big-endian byte order.
|
|
[u32] signature: 'MTSM'
|
|
[u16] version: 4
|
|
[u16] size X
|
|
[u16] size Y
|
|
[u16] size Z
|
|
For each Y:
|
|
[u8] slice probability value
|
|
[Name-ID table] Name ID Mapping Table
|
|
[u16] name-id count
|
|
For each name-id mapping:
|
|
[u16] name length
|
|
[u8[]] name
|
|
ZLib deflated {
|
|
For each node in schematic: (for z, y, x)
|
|
[u16] content
|
|
For each node in schematic:
|
|
[u8] param1
|
|
bit 0-6: probability
|
|
bit 7: specific node force placement
|
|
For each node in schematic:
|
|
[u8] param2
|
|
}
|
|
|
|
Version changes:
|
|
1 - Initial version
|
|
2 - Fixed messy never/always place; 0 probability is now never, 0xFF is always
|
|
3 - Added y-slice probabilities; this allows for variable height structures
|
|
4 - Compressed range of node occurence prob., added per-node force placement bit
