The heart of Tiled support: load a map and draw it.
- rt_tmap model (Tmap/TmLayer/TmTileset in tiled.ludic): map header + ordered
layers (dense int32 GID arrays, heap-allocated to w*h, lifting the 96x64 cap)
+ tilesets. Built from the intermediate Value tree, so the TMX and TMJ paths
both feed it.
- GID resolver (Tiled.resolve): gid -> (tileset, localId, flipH/V/D); the three
flip flags masked off before the local-id lookup, returned alongside. gid==0
is empty.
- Image-backed render (Tiled.draw): every visible tile layer in file order,
blitting each tile from its tileset image with flips applied at draw.
- Compatibility projection (Tiled.project / auto on load): a designated
collision layer projects to the legacy byte tilemap ('#' solid, '=' one-way
via the oneway property, ' ' empty) so Grid.*/Path.*/esys_move are unchanged.
- Tiled.load resolves external tilesets + images relative to the map file and
auto-projects a collision/solids/walls layer.
- The grid and physics_tiles demos now run off a loaded map (grid_maze.tmx /
physics_map.tmx) instead of hand-authored Map.row strings, byte-identically.
Two compiler fixes fell out of this (see the changeset):
- emit_index_addr set g_addr_ty before evaluating the index, so slice[obj.field]
came back mis-typed; set it last, like the raw-pointer branches.
- @strcmp was declared by both the world table and the fs prelude; centralise
it in the head prelude so a game that uses Fs/Path links.
Proven by library/tiled_p1.ludic (14 assertions: loads+renders Kenney map
identically from .tmx and .tmj, flip mirroring) + the converted grid/
physics_tiles demos. x test: 92 passed; self-host bootstrap fixpoint intact.

**Tiled map support (#67–#74)** — load and draw [Tiled](https://www.mapeditor.org/) maps (TMX/TSX/TX and TMJ/TSJ/TJ), the design record from #66.
|
||
|
||
- **P0 parsing primitives (#67)** — a minimal pure-Ludic XML reader (`Xml.*`) for the element/attribute/CDATA subset TMX/TSX/TX use; standard base64 decode/encode (`Base64.*`, RFC 4648), whose decoder ignores the whitespace Tiled wraps into `<data>`; and gzip framing (`z_gunzip`, RFC 1952) wrapping the existing DEFLATE inflater. zlib and the JSON reader already shipped. A curated, attributed golden corpus lands under `assets/tiled-fixtures/`.
|
||
- **P0.5 TMX/TSX reader (#68)** — `Tiled.read` / `Tiled.read_tsx` map the native XML formats onto the *same* intermediate the JSON path produces — a `Value` tree in Tiled's JSON schema, with every tile layer's data decoded to a dense GID list (CSV, base64, base64+zlib, base64+gzip). A CSV `.tmx` and a base64+zlib `.tmj` of the same map read structurally identically; the in-repo Kenney `sampleMap.tmx` + external `sampleSheet.tsx` load with no manual JSON re-export.
|
||
- **P1 core load + render (#69)** — the runtime `rt_tmap` model (heap-allocated to `w·h`, lifting the old `96×64` cap), the GID resolver (`Tiled.resolve` → tileset / local id / H·V·D flips), image-backed rendering (`Tiled.draw`, flips applied at blit), and the legacy-tilemap compatibility projection so `Grid.*`/`Path.*`/`esys_move` keep working. `Tiled.load` reads either format, resolves external tilesets + images, and auto-projects a `collision` layer. The Kenney sample loads and renders pixel-identically from `.tmx` and `.tmj`; the `grid` and `physics_tiles` demos now run off a loaded map.
