Object frames turn by any angle (quarter turns stay exact, so scenes along
the axes render byte for byte as before); a box in a turned frame is a
prism with its own corners. Rotation is kept as given (normalised to
0..360), no longer snapped to quarter turns.
Depth sort: sprites whose plan outline is not their box carry their convex
outline; when boxes overlap, an outline edge that separates two sprites
orders them. A long diagonal wall sorts right against both sides.
Joints (line_meet, end_cut, cut_box in util.rhai): where a piece off the
axes is involved, corners are mitred and T-junctions slanted; fences put a
corner post or pillar in its own sprite and mitre stone bases; Y joints let
the lowest id run through. Streets: every end part is a cut e + k*w, so
side streets come in at any angle (slanted sidewalk gaps), two streets meet
in a mitre with seam patches; fixes a curve's outer sidewalk that was
skipped when its kerb and back lines had different point counts.
Studio: runs and drags keep to x/y or snap to 45 degree diagonals, Ctrl
gives any angle; a road run turning 45 degrees gets a 45 degree curve;
Rotation is a number box. Streets demo: a diagonal lane with a hedge.
MCP guidance, SCRIPTING/README/ROADMAP.
Tests: Rust 76, Studio and web checks green.
Selection: S.sel stays the object picked last; S.selIds holds everything
selected.
- In the object list, Ctrl+click adds or removes an object and
Shift+click selects a range.
- On the map, Ctrl/Shift+click toggles an object and Shift+drag draws a
box that selects what lies wholly inside it (locked and hidden objects
are left out).
- Ctrl+A selects everything that is not locked; Esc selects nothing.
- Clicking a wall or fence a second time selects every piece of the same
type joined to it; another click goes back to that one piece.
- Dragging one selected object moves them all, together with the windows
and doors on them, as one undo step. Arrow keys, R (turns the group
about its middle), Ctrl+D, Delete, Lock and Hide all work on the whole
selection.
- When all selected objects share a type, the property form edits them
all; fields where they differ show "mixed".
- The agent's system prompt lists the selected objects.
The viewer outlines several objects with selectObj([ids]) and passes the
click event to onPick. A batch op now answers `ids`, one per operation,
so the copies from a group duplicate get selected.
Pond (Nature): natural, round or square, with a stone or grass edge,
fish, lily pads, spreading ripples and reed clumps. The fish come from a
new Swim primitive (script: s.swim). One matrix maps the object's frame
to the screen. Each fish turns round its ellipse with a CSS rotation,
so off-screen pausing and reduced motion apply as for the other
animations. The house demo gets a koi pond in the back garden.
Tests: ponds in every shape and rotation have the right number of fish,
no NaN and no depth-sort cycles, and stay inside their rectangle.
check_studio covers list and map multi-select, a group drag undone in
one step, joined-fence selection, a mixed-value form applied to all, box
select, delete and undo, Ctrl+A, Esc, and a new pond's fish.
House parts (stdlib isokit/house): house_wall drawn along a line, with ends
that adapt at corners, T-junctions and straight runs so no two walls
overlap; window and door that sit on a wall and cut its opening (door
styles panel, glass, double, sliding, opening; swing and hinge by
rotation); floor (boards, tiles, carpet, stone); roof (hip, gable, flat,
optional solar); stairs.
Furniture (stdlib isokit/furniture): chair, sofa / armchair, table with
chairs, desk with monitor and chair, TV, bed, cupboard, bookshelf, kitchen
run, bathtub, shower, toilet, washbasin, plant, rug, floor lamp.
Cut-open levels: on gf / 1f the walls in front of a room are cut low
(rooms are found by their floors), the roof becomes an outline on the
floor, and storeys above are left out. A part's storey comes from z
(storey_h, default 3 m).
Scripting: objects_of, objects_at, objects_on, mount_of, mounted, frame,
to_world, to_local, local_of. Prefab meta: shape (line / rect), mount,
storey.
Studio: drag to draw lines and rectangles (walls, roads, fences, hedges,
floors, areas, buildings, roofs). The Room tool draws a floor plus walls,
without doubling walls that already stand on an edge. Windows and doors
snap onto walls with a hover preview, and they move, turn, copy and
delete with their wall in one undo step. New parts land on the storey
the view shows. Palette categories collapse, and the palette scrolls
apart from the object list.
The MCP instructions explain house building, and list_prefabs shows
sits_on. examples/house is a furnished bungalow; the web Studio gets a
House demo button. Tests: wall corners and junctions, zero depth-sort
cycles in every view, cut levels, and the house demo in every view;
check_studio covers the room / window / door / storey flow, check_web
the House demo.
