Flag Placement Errors in Pokopia: Visual Breakdown of Valid House Boundaries
Meeting the enclosed room requirements demands structural discipline that the game never explicitly details in early tutorials. Diagonal walls present the single most frequent point of failure. While blocks placed diagonally might appear solid to the naked eye, the engine treats corners touching only at their edges as open gaps. Every perimeter wall must connect orthogonally along its faces to preserve an airtight boundary.
Door frames introduce a separate set of collision traps. A simple gap in the wall does not qualify as an entrance, nor does a raw door leaf attached directly to loose planks. You must set down an official door frame piece before snapping the actual swinging door inside it. If you build the frame backward, with the exterior sill facing the living quarters, the system reads the interior as exterior terrain, causing a sudden habitat registration fix roadblock that leaves the flag inactive.
Floor tile boundaries present another hidden pitfall. Digging out dirt and throwing a rug over bare grass does not register as a floor. A valid room demands manufactured tiles: packed wood, chiseled stone, or processed clay. These tiles must sit flush across the entire interior area. Leaving a single exposed patch of natural soil or sand in the corner immediately disqualifies the perimeter, dropping structural integrity scores to zero.
