CollisionProcessor2D | Grid Placement Docs

Draft — Unreleased:This page is in active development. APIs, class names, and behavior may change before the release is finalized. Use it as a preview of what's coming — not as a stable integration target.

Unified Collision Processor Handles processing for both CollisionObject2D (with shapes) and CollisionPolygon2D. Converts collision geometry to relative tile offsets for indicator positioning. [b]CRITICAL:[/b] Must use positioner.global_position as coordinate reference to maintain relative offsets. Using collision object position causes positioning displacement.
