Enum MapPatternType

Geometric pattern types that can be stamped onto an existing grid by ApplyPatternOverlay(ScyllaSquareGrid<int>, int, int, MapOverlaySettings) to add repeating visual detail on top of already-generated floor cells.

Pattern overlays do not generate new map structure; they only reclassify cells that already exist in the grid according to a deterministic geometric rule. When OnlyAffectFloors is true, only cells whose current value matches the specified floor value are candidates for modification. This prevents the overlay from overwriting walls or corridor cells.

Patterns are evaluated using the column and row indices of each cell relative to the grid origin. The same pattern applied to different grid sizes will tile consistently because the matching rules depend only on the local column/row modulus, not on the absolute grid dimensions (except Border, which is perimeter-relative).

Fields

Name Description
Border

A border ring pattern that marks only the outermost ring of cells along the grid perimeter - those whose column index is 0 or gridWidth - 1, or whose row index is 0 or gridHeight - 1. This is useful for framing the playable area with a decorative or structural border, or for marking wall-adjacent floor cells as edge tiles without requiring a full connectivity pass.
Checker

An alternating checkerboard pattern where every cell at an even sum of column and row indices ((col + row) % 2 == 0) is marked. This produces a classic two-color grid pattern that is useful for tile variety, anti-aliasing large floor areas visually, or marking interactable cells on a regular cadence.
DiagonalStripes

A diagonal stripe pattern where cells whose column-plus-row sum falls within the first half of a period-4 cycle ((col + row) % 4 < 2) are marked. This produces stripes that run at a 45-degree angle across the grid, alternating between two-cell-wide marked and two-cell-wide unmarked bands. Useful for diagonal flooring motifs or decorative tile borders.
HorizontalStripes

A horizontal stripe pattern where every even-indexed row (row % 2 == 0) is marked, creating alternating horizontal bands of marked and unmarked cells. Useful for adding horizontal banding to large open floor areas, such as plank flooring or alternating tile colors running left-to-right across the grid.
VerticalStripes

A vertical stripe pattern where every even-indexed column (col % 2 == 0) is marked, creating alternating vertical bands of marked and unmarked cells. Useful for adding vertical banding to large open floor areas, such as column motifs or alternating tile colors running top-to-bottom across the grid.
