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.
