State + actions:
- active_flip (0/1) joins active_rot (0..3). Combined the two cover
all 8 D4 orientations; single Flip button is sufficient (H+V
would be redundant).
- toggle_flip / reset_transform / paint_override_at /
erase_override_at.
Toolbar:
- New Flip (H) + Reset (0) buttons next to Rotate (R).
- Status chip extended with `slot=N rot=N flip=N` indicator.
Paint:
- Direct-mode + LMB on canvas now calls maps.set_override on the
active material-bound terrain layer. Bare slot int when canonical
(rot=0+flip=0), {slot, rot, flip} object otherwise — matches the
v0.5.1 override-format extension. Palette slot 1..14 maps to lib
slot 0..13 (palette is user-friendly 1-based; lib API is 0-based).
- Direct-mode + RMB on canvas calls maps.clear_override.
- Auto-Tile mode unchanged; transform state is ignored there (the
renderer derives slot/rot/flip from the vertex bitmask).
Hotkeys:
- h -> flip (new)
- 0 -> reset_transform (new)
- r continues to cycle rotation CW; Shift+R for CCW is out because
lib-core.input has no modifier-combo support (deferred).
Cheatsheet rows updated.
sporel-module-map-editor
Interactive map editor for v2 Sporel map files. Click-to-paint, vertical layer-chip overlay on the left edge, collapsible atlas+tile picker bottom-left.
Run
Default — edit the module's in-place work map:
bash scripts/run-map-editor.sh
With a target — copy a real map in, edit, copy back out:
bash scripts/run-map-editor.sh ~/Projects/Sporel/sporel-modules/spine-prototype/maps/demo.map.json
UI
- Layer chips (left edge, vertical): top-of-stack down.
Rfat top toggles roof-edit mode; the other eight chips select the active layer.- Left-click = set active layer (or toggle roof mode)
- Right-click = toggle layer visibility (Rf chip ignores right-click)
- Atlas + tile picker (bottom-left): collapsed chip shows the active tile. Click to expand; click again or outside to collapse.
- Status chip (bottom-right): current mouse-cell coordinate plus a
*when the map has unsaved changes.
Hotkeys
| Key | Action |
|---|---|
Left click on map |
Paint cell with active tile (or set roof flag in roof-mode) |
E |
Erase the cell under the mouse |
R |
Cycle rotation 0 → 1 → 2 → 3 → 0 |
S |
Save to disk (overwrites the work map) |
Esc |
Quit |
Limitations (v0.1.0)
- Tile thumbnails in the picker render as gray placeholders with tile-IDs as text — lib-core.maps v0.4.0 does not expose per-tile UVs to Lua, so visual thumbnails are a v0.2.0 task.
- Atlas list in the picker is purely informational; if a map declares multiple atlases, the active atlas is set from
state.luadefaults at startup and cannot yet be switched via UI (v0.2.0 hit-tests inside the expanded picker). - Engine bindings
engine.render.draw_rect_linesandengine.render.draw_lineare not yet registered — active-chip borders, hidden-layer strikethroughs, and the entity-slot divider will trigger runtime errors when their code paths execute. Adding the bindings is a small engine-side follow-up. - No undo/redo, no multi-tile brush, no entity placement, no heightmap editing — see the design spec §1 for the full out-of-scope list.
