Build the PixelLab part library (64x64 sprites, registry: sprite_parts_pl.py).
|
|
|
|
Each base creature has a spec, pixellab_library/<body>.json. The base is generated once with
|
|
PixelLab's pixen model; every part is an edit of that exact image ("add horns ...") made with
|
|
edit-image-pixen, and the part is the pixel difference between the edit and the base. All art
|
|
is drawn in a stand-in palette (teal body = main, crimson = accent, gold = type) that maps to
|
|
the palette keys, so the generator can recolor it with brand colors.
|
|
|
|
Workflow
|
|
python pixellab_library.py generate pl_fox --base-only # base only (pixellab_src/pl_fox/base.png): review it first
|
|
python pixellab_library.py generate pl_fox # every missing edit
|
|
python pixellab_library.py extract pl_fox # grids parts_pl_src/, PNGs parts_pl/, diffs preview/pixellab/diff/
|
|
python pixellab_library.py preview pl_fox # preview/pixellab/body_pl_fox.png
|
|
python pixellab_library.py generate pl_fox --parts pl_tail_flame --force # redo one edit (new seed!)
|
|
python pixellab_library.py preview --cross # every part on every body: preview/pixellab/cross_<slot>.png
|
|
python pixellab_library.py preview --random 60 # real random picks: preview/pixellab/random.png
|
|
python pixellab_library.py cost # spend so far (ledger) and live balance

Probes: every accepted slot with no real part gets a probe edit (a standard gold horn pair, wing
|
|
pair or tail; PROBE_EDITS) that extract uses only to find that slot's anchor. A new concept
|
|
therefore needs no parts: base + 3 probes, plus 1 edit per variant.
|
|
|
|
Conventions every base and edit must follow so parts mix across bodies
|
|
- Front or 3/4 view facing the viewer (direction south / south-west), feet at the bottom.
|
|
- Tails come out on the image's RIGHT side. Wings and horns are symmetric pairs.
|
|
- Body in teal, details crimson; generic elemental features gold (type ramp, recolored per
|
|
type); fixed-color features in their natural colors (orange/yellow fire, pale ice, ...).
|
|
- The base creature fills its pixen canvas; at 64x64 it should leave room for features
|
|
(height <= ~46px, width <= ~48px).
