PixelLab Top-Down

Class: PentaTileLayoutPixelLabTopDown

PixelLab Top-Down reads PixelLab's 8x8 top-down tileset output. It is a single-grid 4-bit corner-mask layout.

PixelLab outputs multiple cells for some masks. In v0.2, PentaTile picks the row-major first cell deterministically. Variation-bank selection is deferred to future variation work.

Template

Atlas contract

Property	Value
Grid	8 columns x 8 rows
Tile count	64 cells
Mask bits	TL=1, TR=2, BL=4, BR=8
Dispatch	PixelLab cell-to-role table, then role-to-mask cache
Grid type	single-grid
Rotation reuse	none

Setup

1. Generate or import a PixelLab top-down tileset output.
2. Add PentaTileMapLayer.
3. Set layout to PentaTileLayoutPixelLabTopDown.
4. Assign the PixelLab atlas as the layer tile_set, or use the fallback template for quick testing.

Authoring notes

• The PixelLab table contains variation banks. PentaTile v0.2 deliberately uses the row-major first matching cell for deterministic output.
• Full variation-bank selection is deferred until the broader variation design.
• This is single-grid, so each rendered state should be a complete tile.
