# B01 - Unnamed building  `OVERWORLD` tileset, **4 x 3 cells** (8 x 6 tiles of 8px, 64 x 48 px). Appears **19 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..4, y=1..3; tile column c=1..8, tile row r=1..6. No terrain padding is included - edge rows and columns that were pure ground have been trimmed. ## Symbol grid ``` x1 x2 x3 x4 +-----+-----+-----+-----+ y1 | A B | C C | C C | D E | | F G | H H | H H | I J | +-----+-----+-----+-----+ y2 | K L | M M | M M | N O | | P Q | Q Q | R R | R S | +-----+-----+-----+-----+ y3 | P M | M M | M M | M S | | T U | U U | U U | U V | +-----+-----+-----+-----+ ``` ## Same grid, raw tile ids ``` x1 x2 x3 x4 +---------+---------+---------+---------+ y1 | 5 6 | 7 7 | 7 7 | 8 9 | | 21 22 | 23 23 | 23 23 | 24 25 | +---------+---------+---------+---------+ y2 | 37 38 | 10 10 | 10 10 | 40 41 | | 15 34 | 34 34 | 75 75 | 75 31 | +---------+---------+---------+---------+ y3 | 15 10 | 10 10 | 10 10 | 10 31 | | 78 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, 8, 9 }, -- r1 { 21, 22, 23, 23, 23, 23, 24, 25 }, -- r2 { 37, 38, 10, 10, 10, 10, 40, 41 }, -- r3 { 15, 34, 34, 34, 75, 75, 75, 31 }, -- r4 { 15, 10, 10, 10, 10, 10, 10, 31 }, -- r5 { 78, 26, 26, 26, 26, 26, 26, 79 }, -- r6 } ``` ## Legend _Legend pending._ - `A` = tile 5, used 1x - `B` = tile 6, used 1x - `C` = tile 7, used 4x - `D` = tile 8, used 1x - `E` = tile 9, used 1x - `F` = tile 21, used 1x - `G` = tile 22, used 1x - `H` = tile 23, used 4x - `I` = tile 24, used 1x - `J` = tile 25, used 1x - `K` = tile 37, used 1x - `L` = tile 38, used 1x - `M` = tile 10, used 10x - `N` = tile 40, used 1x - `O` = tile 41, used 1x - `P` = tile 15, used 2x - `Q` = tile 34, used 3x - `R` = tile 75, used 3x - `S` = tile 31, used 2x - `T` = tile 78, used 1x - `U` = tile 26, used 6x - `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 y2 SOLID SOLID SOLID SOLID y3 SOLID SOLID SOLID SOLID ``` Every cell is solid - this building has no door of its own. ## Silhouette 186 of the 3072 px inside the box are ground outside the black outline, so the 64x48 box is **not** a solid rectangle - a pixel-perfect cutout has to follow the outline.
