Building and wall finishes
Placement cursor
Section titled “Placement cursor”The Knox cursor is a real construction cursor, not a visual-only ghost. It uses the selected buildable’s directional sprite data and multi-tile footprint to preview the object before placing it.
It checks Build 42-style constraints including:
- floor and wall support;
- wall edge direction;
- predecessor construction stages;
- door/window frame requirements;
- multi-tile collisions;
- vehicle and stair conflicts;
- stackable furniture placement;
- safehouse, distance and server-access restrictions.
The character walks to an appropriate adjacent square before performing the timed action. Large and wall-like objects use their footprint/direction to find the appropriate interaction position.
Construction levels and upgrades
Section titled “Construction levels and upgrades”Some buildables are related by groups. A group presents wall quality or a similar family as one catalogue entry; the selected carousel item resolves to the real underlying recipe.
Other stages are upgrades. An upgrade can require a prior wall/frame/object and will only replace it when the required stage and direction match. This permits frame-to-wall construction without treating a valid frame as a collision.
Finish selection for new walls
Section titled “Finish selection for new walls”Plasterable normal walls can be built as:
- Bare wall.
- Plastered wall.
- Plastered wall plus an allowed paint colour.
- Plastered wall plus an allowed wallpaper type.
The finish selector previews the final mapped sprite. Knox first builds the wall, then queues the finish actions in order: plaster first, then paint or wallpaper.
| Finish action | Tools retained | Items used |
|---|---|---|
| Plaster | plastering trowel | plaster bucket use |
| Paint | paintbrush | selected paint use |
| Wallpaper | paintbrush and scissors | selected wallpaper and paste uses |
The trowel may degrade. Every finish requirement appears in the catalogue and blueprint totals before construction.
Standalone wall-covering actions
Section titled “Standalone wall-covering actions”The converted wall-covering catalogue also supports actions on existing walls:
- plaster;
- wall painting;
- wallpaper;
- paintable sign variants.
These actions use the same item/tool gates as their Build 42 counterparts. The available paint, wallpaper or sign selector is validated against the selected action rather than accepting a generic client-side choice.
In planning mode, a finish ghost belongs to one wall edge rather than the whole tile. Empty tiles and incompatible surfaces render as invalid. A plaster plan may be followed by paint or wallpaper on the same edge; the build queue applies them in that order. Tile-pack surfaces can also explicitly permit direct paint or wallpaper without plaster.
