# B17 - Unnamed building  `OVERWORLD` tileset, **6 x 2 cells** (12 x 4 tiles of 8px, 96 x 32 px). Appears **3 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..2; tile column c=1..12, tile row r=1..4. No terrain padding is included - edge rows and columns that were pure ground have been trimmed. ## Symbol grid ``` x1 x2 x3 x4 x5 x6 +-----+-----+-----+-----+-----+-----+ y1 | A B | C C | C C | C C | C C | D E | | F G | H H | H H | H H | H H | I J | +-----+-----+-----+-----+-----+-----+ y2 | K L | M N | O P | P O | P P | Q R | | S T | * U | T T | T T | T T | T V | +-----+-----+-----+-----+-----+-----+ ``` ## Same grid, raw tile ids ``` x1 x2 x3 x4 x5 x6 +---------+---------+---------+---------+---------+---------+ y1 | 5 6 | 7 7 | 7 7 | 7 7 | 7 7 | 8 9 | | 21 22 | 23 23 | 23 23 | 23 23 | 23 23 | 24 25 | +---------+---------+---------+---------+---------+---------+ y2 | 37 38 | 11 12 | 35 10 | 10 35 | 10 10 | 40 41 | | 78 26 | 27 28 | 26 26 | 26 26 | 26 26 | 26 79 | +---------+---------+---------+---------+---------+---------+ ``` As a 1-based Lua array, `rows[r][c]`: ```lua local rows = { { 5, 6, 7, 7, 7, 7, 7, 7, 7, 7, 8, 9 }, -- r1 { 21, 22, 23, 23, 23, 23, 23, 23, 23, 23, 24, 25 }, -- r2 { 37, 38, 11, 12, 35, 10, 10, 35, 10, 10, 40, 41 }, -- r3 { 78, 26, 27, 28, 26, 26, 26, 26, 26, 26, 26, 79 }, -- r4 } ``` ## Legend _Legend pending._ - `*` = tile 27, used 1x - `A` = tile 5, used 1x - `B` = tile 6, used 1x - `C` = tile 7, used 8x - `D` = tile 8, used 1x - `E` = tile 9, used 1x - `F` = tile 21, used 1x - `G` = tile 22, used 1x - `H` = tile 23, used 8x - `I` = tile 24, used 1x - `J` = tile 25, used 1x - `K` = tile 37, used 1x - `L` = tile 38, used 1x - `M` = tile 11, used 1x - `N` = tile 12, used 1x - `O` = tile 35, used 2x - `P` = tile 10, used 4x - `Q` = tile 40, used 1x - `R` = tile 41, used 1x - `S` = tile 78, used 1x - `T` = tile 26, used 8x - `U` = tile 28, used 1x - `V` = tile 79, used 1x  ## Collision Cell walkability reads the **bottom-left 8px tile** of each cell (`src/world/Map.lua:6`): ``` y1 SOLID SOLID SOLID SOLID SOLID SOLID y2 SOLID DOOR SOLID SOLID SOLID SOLID ``` Enterable cell: (2,2). ## Silhouette 154 of the 3072 px inside the box are ground outside the black outline, so the 96x32 box is **not** a solid rectangle - a pixel-perfect cutout has to follow the outline.
