hght
files describe the heightmap of the main field and add-on content field.
HGHT File Specification
hght
files contain no header or signature.
hght File Layout
hght
files only contain a table of height data. There are 65,536 (256×256) unsigned short entries in the table.
Each file describes a 256×256 mesh tile. Each tile has placement data found in MainField.tscb
.
Height Map Data
Each entry in the table maps to an x
, y
and z
component. The height or y
component of each vertex is the value read the from the file.
Offset (h) | Size | Data Type | Description |
---|---|---|---|
0x00 | 2 | Unsigned Short | Vertex y component
|
x
and z
[1] can be calculated, while iterating through the data table:
for (int index = 0; index < 256 * 256; index++) {
uint x = index % 256;
uint z = index / 256;
}
- ↑ `z` is expected to be an integer quotient. The `floor` function can be used if integer division is not supported.
