RuleTrace Kit — RuleTile Debugger & Coverage Preview

RuleTrace Kit is a Unity Editor tool for understanding why a standard RuleTile selects a specific rule.

Analyze all 256 square-neighbor relationships, inspect overlaps and shadowed rules, check real Tilemap cells, and compare virtual rule order without modifying your source RuleTile.

Key features:

• Overview

See rule counts, selected relationships, fallback results, overlaps, matching counts, selected counts, and shadowing information.

• Pattern Browser

Explore all 256 square 3×3 neighbor relationships and inspect which rules match and why one is selected.

• Tilemap Cell Inspection

Inspect a real Tilemap cell and compare the predicted rule with the currently observed Sprite and transform matrix.

• What-if Rule Order

Reorder virtual rule slots and recalculate results without changing the source RuleTile.

• Scenario Save / Load

Save local What-if scenarios and load them later with source identity checks.

• Markdown Export

Export original and virtual rule-order comparisons to a Markdown report.

• Included Samples

Includes diagnostic RuleTiles, Sprite assets, and a demo Tilemap scene.

Requirements:

• Unity 6.3 LTS verified

• 2D Tilemap Extras 6.0.3

• Editor-only tool

Verified scope:

• Official basic RuleTile

• Square 3×3 neighbors

• This / NotThis / Don'tCare

• Fixed, Rotated, MirrorX, MirrorY, MirrorXY, and RotatedMirror matching

Not included in the verified scope:

• Custom RuleTile subclasses

• Hexagonal or Isometric-specific logic

• Multi-Tilemap relationships

• Automatic rule fixing or source reordering

• Final Random/Animation frame evaluation

• Pixel, collider, or GameObject evaluation

RuleTrace Kit does not modify your source RuleTile during analysis.
