| GRAFFITI_MAX_LAYERS | Most layers one graffiti piece holds. |
|---|---|
| GRAFFITI_MAX_LAYER_NAME | Longest layer name, in characters. |
| GRAFFITI_MAX_NAME | Longest piece name, in characters. |
| GRAFFITI_MAX_DESCRIPTION | Longest piece description, in characters. |
| GRAFFITI_WIDTH | Width of a piece that covers one tile. |
| GRAFFITI_WIDE_WIDTH | Width of a piece that covers two tiles side by side. |
| GRAFFITI_HEIGHT | Height of every piece. |
| GRAFFITI_MAX_COLORS | Most colours one piece's palette may hold: as many as one grid character can index. |
| GRAFFITI_ALPHA_CEILING | The most alpha placed graffiti is drawn with, 80%, so the surface shows through: a colour this opaque or more is stored opaque, and opaque paint is drawn at it. |
| GRAFFITI_LIBRARY_CAP | Most pieces an account's library keeps, besides its Unfinished slot. |
| GRAFFITI_STACK_CAP | Most pieces stacked on one tile. A full stack refuses new paint. |
| GRAFFITI_COST | Spraycan charges a finished piece costs, halved for taggers. |
| GRAFFITI_COMPOSITE_SHARE_BURST | How many ms of composites may build up for a burst. |
| GRAFFITI_REVEAL_STRIP | Width of the column strip one paint job step reveals, in pixels. |
| GRAFFITI_MISS_LIMIT | Rounds in a row a placement may miss its surface: the last of them drops it. |
| GRAFFITI_PIECE_MAX_BYTES | Size limit of one exported or imported piece. |
| GRAFFITI_LIBRARY_WRITE_PACE | A player's library write waits this many times as long as the account's last write took, and at least a second, so one account's writes take at most a twentieth of the server's time: 50 adversarial pieces take 139 ms to write on average and 209 ms at most (measured), 14-21% of the time at one write a second. |
| GRAFFITI_MAP_MAX_BYTES | Size limit of a map's graffiti file. |
| GRAFFITI_MAP_DIRECTORY | Where each map's graffiti file lives. |
| GRAFFITI_SHEET_DIRECTORY | Where each map's sprite sheet files live, in a directory per map. |
| GRAFFITI_LIBRARY_DIRECTORY | Where each account's library file lives. |
| GRAFFITI_MAP_UNIQUE_CAP | Most unique arts one map file keeps: 2,000 dense art records of 3,670 bytes take 7.3 MB, as measured, and a sparse one takes 680 bytes. |
| GRAFFITI_MAP_PLACEMENT_CAP | Most placements one map file keeps: 4,000 placements packed as JSON strings take about 1.2 MB (measured on a full map), and their decals at 2,261 bytes each 9 MB at worst. With the arts (at most about 5.4 MB under GRAFFITI_MAP_ART_BYTES) and the GRAFFITI_ICON_CACHE caches (1.5 MB) that is about 17 MB at worst, besides the placement indexes (not measured), since sheet files keep every other icon at 0 bytes of server memory; a load adds GRAFFITI_DECODE_BUDGET while it runs. |
| GRAFFITI_MAP_ART_BYTES | Most bytes of art one map keeps, counting each unique art's pal, grid and glow text: about 1,500 dense
one-tile arts, or 400 translucent ones of 1,000 colours at 12-14 KB a tile, while typical art meets
GRAFFITI_MAP_UNIQUE_CAP first. The owner's ruling (2026-10-20) halved it from 10 MiB, which takes the worst case at
the caps from about 22.5 to 17 MB; 10 MiB of art and 4,000 placements wrote about 13.5 MB, so 5 MiB writes about
8 MB. Both new figures are worked out from the measured ones at 10 MiB. |
| GRAFFITI_DISPLAY_BUDGET | Most unique arts shown in one round: everything within the map caps. Ranking still orders evictions and loading. |
| GRAFFITI_CKEY_PLACEMENT_CAP | Most placements one account keeps on one map: a tenth of GRAFFITI_MAP_PLACEMENT_CAP. |
| GRAFFITI_FORMAT | The format every piece file carries. A file with any other is refused. |
| GRAFFITI_FORMAT_VERSION | The piece file version this server writes and accepts. |
| GRAFFITI_MAP_VERSION | The map file version this server writes: anchors record their surface, and placements carry no name or description. |
| GRAFFITI_ANCHOR_STATION | Anchor kind of a placement on a fixed station tile. |
| GRAFFITI_ANCHOR_RESERVED | Anchor kind of a placement in reserved space, such as a condo. |
| GRAFFITI_KIND_WALL | graffiti_surface_kind() of a wall. Anchors keep the kind as their surface, and decals as their kind. |
| GRAFFITI_KIND_FLOOR | graffiti_surface_kind() of a floor with ground. |
| GRAFFITI_KIND_WINDOW | graffiti_surface_kind() of a tile under a full-tile window fastened down, whose graffiti is on the glass. |
| GRAFFITI_ADMIN_PAGE | Placements per page of the admin panel. |
