# B18 - Unnamed building
|
|
|
|

|
|
|
|
`OVERWORLD` tileset, **6 x 4 cells** (12 x 8 tiles of 8px, 96 x 64 px). Appears **2 times** 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..6, y=1..4; tile column c=1..12, tile row r=1..8. No terrain padding is included - edge rows and columns that were pure ground have been trimmed.

## Collision

|
|

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

## Silhouette
|
|
|
|
258 of the 6144 px inside the box are ground outside the black outline, so the 96x64 box is **not** a solid rectangle - a pixel-perfect cutout has to follow the outline. Terrain pixels by tile row:
|
|
|
|
```
|
|
r1 c1:25px, c12:25px
|
|
r2 c1:24px, c12:24px
|
|
r3 c1:24px, c12:24px
|
|
r4 c1:24px, c12:24px
