# B34 - Unnamed building

![Unnamed building](img/B34_x10.png)

`OVERWORLD` tileset, **4 x 2 cells** (8 x 4 tiles of 8px, 64 x 32 px). Appears **1 time** in the game. Tile ids index `assets/generated/tilesets/overworld.png`, 16 per row.

Coordinates are 1-based and local to the building: cell x=1..4, y=1..2; tile column c=1..8, tile row r=1..4. No terrain padding is included - edge rows and columns that were pure ground have been trimmed.

As a 1-based Lua array, `rows[r][c]`:

```lua
local rows = {
  {   5,   6,   7,   7,   7,   7,   8,   9 },  -- r1
  {  21,  22,  23,  23,  23,  23,  24,  25 },  -- r2

## Collision

Cell walkability reads the **bottom-left 8px tile** of each cell (`src/world/Map.lua:6`):

```
    y1   SOLID  SOLID  SOLID  SOLID
    y2   SOLID  SOLID  SOLID  SOLID
```

Every cell is solid - this building has no door of its own.

## Silhouette

154 of the 2048 px inside the box are ground outside the black outline, so the 64x32 box is **not** a solid rectangle - a pixel-perfect cutout has to follow the outline. Terrain pixels by tile row:

```
    r1   c1:48px, c2:16px, c7:16px, c8:48px
    r3   c1:5px, c8:5px
    r4   c1:8px, c8:8px
```

## Where it stands

| map | cell (x,y) | door | leads to |
| --- | --- | --- | --- |
| FUCHSIA_CITY | (14,26) | - | scenery, no entrance |
