# Set format information
|
|
|
|
`*.set` files seem to act as a palette of objects for a [`.map`](maps.md) file.
|
|
The map file loads a set, and can then reference objects by a small number.
|
|
|
|
Since a maximally-filled map file seems to be able to reference 91,000 * 4
|
|
objects, this is a necessary optimization for 1998-era hardware.
|
|
|
|
## Structure
|
|
|
|
These files are plain-text.
|
|
|
|
We handily have a `template.set`, which looks like:
|
|
|
|
```
|
|
set template
|
|
|
|
Defs
|
|
|
|
40 40 40 80
|
|
|
|
|
|
dirt
|
|
h_dirt
|
|
rocks
|
|

# ...
|
|
```
|
|
|
|
The files are of varying lengths. `template.set` is 220 lines, `map10.set` only
|
|
83.
|
|
|
|
So it's a line-based format that goes:
|
|
|
|
* Set description
|
|
* Blank line (optional, missing in `GEN_JUN.set`, `GEN_WAS.set`, others)
|
|
* `Defs`
|
|
* Blank line
|
|
* 4 space-separated numbers, variable between sets
|
|
* At least one blank line, sometimes 2
|
|
* A list of object names, sometimes with # comments on the right hand side
|
|
* They all seem to end with a comment of some sort, e.g. `# meaningless comment`
|
|
|
|
Questions:
|
|
|
|
What are the `Defs` for? Is it `Defaults` or `Definitions`? The values are
|
|
quite variable between files.
|
|
|
|
Is whitespace significant in the list of objects? First assumption is no.
|
|
|
|
Is it a simple 0-indexed palette or do maps embed an absolute line number?
|
|
|
|
Do positions in the palette have special meaning? e.g. is a particular range
|
|
always reserved for walls?
|
|
|
|
Are there any special values that don't appear as files in the `Obj/` directory?
|
|
`blank.obj` exists, so I expect not.
|
|
|
|
Once the map format is fleshed out a little more, can investigate by creating a
|
|
map with a single object from the set in it and seeing what line that works out
|
|
to be.
