Replace Tile Pattern

Replaces matching tiles with a procedural pattern such as checkerboards, stripes, or rings.
Ideal for generating patterned floors, alternating wall sections, or stylized dungeon layouts.
Checker Square Rings Noise

Parameters

Field Description
Tilemap The target Tilemap.
Bounds Optional area to process. Defaults to the Tilemap’s full bounds.
Match Tile Only cells containing this tile are replaced.
Keep Original Chance to keep the original tile instead of the new pattern tile.
0 = keep no tiles; 1 = keep all tiles; 0.5 = keep roughly 50% of the tiles.
Pattern Pattern type:
• Checker - alternating blocks
• Stripe X / Y - vertical / horizontal bands
• Diagonal - diagonal alternation
• Rings - concentric circles
• Diamond Rings - 45° diamond rings
• Square Rings - axis-aligned square rings
• Noise - Perlin-noise threshold
Tile A / Tile B Tiles used for pattern fill (A = even, B = odd). Either can be empty to clear cells.
Cell Size Size of pattern blocks (e.g., 1 = 1×1, 2 = 2×2). Hidden for Noise.
Period Stripe or ring spacing (cells). Hidden for Noise.
Noise Threshold Perlin-noise cutoff [0-1]. Shown only for Noise.
Origin Mode Pattern alignment:
• Global Alignment - anchored to the Tilemap grid for seamless tiling.
• Local Alignment - centered in this region.
• Custom Origin - explicit world-cell position.
Custom Origin Used when Origin Mode = Custom Origin.
Phase Offset Extra offset added to origin (useful for shifting patterns).

How it Works

  1. Finds all cells containing Match Tile.
  2. Computes pattern coordinates relative to the chosen Origin Mode.
  3. Evaluates the selected pattern formula (Checker, Stripe, Rings, etc.).
  4. Applies Tile A or Tile B accordingly in a single SetTiles batch.

For Rings, Diamond Rings, and Square Rings, the pattern is centered automatically based on the chosen Origin Mode (Global, Local, or Custom).

Tips

  • Use Global Alignment to keep patterns continuous across adjacent rooms.
  • Use Local Alignment to center the pattern inside each region.
  • Use Custom Origin for precise manual control or to synchronize multiple maps.
  • Either tile can be empty to create cut-out or checker-void patterns.
  • You can also match on null to replace empty tiles.
  • Combine with Tilemap → Replace Tile for richer variation—e.g., checker pattern first, then randomize each color’s texture.
