Project a vertex AND compute its lit colour in one call. Does RTPS on `vert` + NCCS on `normal`, with a per-vertex `material` RGB loaded into RGBC (d

Source-tree projects directory: `editor/projects/`. Captured via `env!("CARGO_MANIFEST_DIR")` at compile time, so it resolves wherever cargo built th

Execute a command received on the command port. The command's handler synthesises its first (and optional second) response and schedules them into the

Render a path relative to the project root when possible, else the full path. Import records store project-relative paths so projects stay relocatable

Like [`saturate_ir`] but only sets the flag -- does not store. Used when the flag for one IR slot needs to reflect a different value than the one stor

Persist the current `Settings` to `settings.ron`. Called when a settings-panel control commits a change.

Schedule a second-response IRQ. `additional_delay` is time after* the first response interrupt actually fires. Matches Redux's `AddIrqQueue(cmd + 0x10

Set the full button mask in one call.

Reallocate the target to the requested internal scale. Cheap when unchanged. Reallocation clears the new texture to opaque black; callers should resyn

Prepend the shared PSX pixel-semantics header (blend modes, dither, tint modulation, plane evaluation, flag constants) to a shader body. WGSL has no i

Wall shape id, see `psxed_format::world::wall_shape`.

Sine in Q12 fixed point.

Reset the camera around a player position using an explicit orbit yaw. Useful for editor/playtest starts where the authored player yaw should affect t

Resolve one triangle for `split_id`. Indices other than zero select the second triangle.

Step a single load/store at the BIOS reset vector with `$a0` (rs=4) preset to `base`. Returns the post-step CPU + bus so callers can inspect COP0 and

Stop embedded play mode and return the editor viewport to the authored 3D preview.

Switch the editor to author the UI scene at `index`. Clamps the index, resets the UI-node selection so a stale node id from the previous scene is neve

Transform a textured world-space vertex to camera-space.

Convert to a local clip index if present.

Move the cursor one visible step backward. The live `current` document is inserted where the restored state came from, so redo remains the exact inver

Wall UVs `[bottom-left, bottom-right, top-right, top-left]`.

Number of walls belonging to this sector.

Run the real BIOS long enough to install its RAM kernel state.

Return options with a signed depth bias.

Set the vertical (elevation) offset, for stacked-floor collision rooms. Builder form keeps the common offset_y=0 constructors terse.

Inverse of [`Self::editor_to_world_cells`]. World coords (post-`/sector_size`) returned from a 3D ground-plane hit land back in the editor's sector-un

Active UI scene, mutable.

Insert a primitive struct. The struct must be `#[repr(C)]` with its first field being the tag `u32`. `words` is the number of data words that follow t

Apply a new Y to every member of `vertex`. X / Z are preserved by construction -- `face_corner_world` returns the current `(X, Y, Z)` and we only ever

Press on a primitive: select it AND arm a drag. The drag itself doesn't apply any height change yet -- that happens in `update_primitive_drag` once th

Build the portal-visible room set. `room_bounds` is accepted for compatibility with callers that already collect room occupancy diagnostics. Visibili

Run the CPU rasterizer's triangle setup for a primitive. `v` must be the vertices in ORIGINAL submission order (the top-left attribute anchor is deri

Convert local stick axes into a world-space camera-relative movement vector. `strafe` and `forward` are centred stick values, usually in `[-axis_max,

Baked ceiling vertex lighting for a sector, if this room carries static lighting.

World-space X coordinate of the left edge of column `sx` (array index, not world-cell index). Accounts for `origin` so the renderer and picking always

Pick the clip index for an animation state, with cheap deterministic fallbacks for unassigned optional actions.

Test `index`.

Dispatch one monochrome rectangle. `xy` is the top-left (already includes drawing-offset). Width/height of zero are dropped silently to match the CPU

Read a sub-rect back as `Vec<u16>` (length `w*h`, row-major).
