PlacementGridRotationUtils

Grid-aware object rotation utilities for 2D grid-based games. Provides clean, typed helper functions for rotating objects on a grid with proper alignment to grid tiles, particularly for isometric and square tile layouts. Supports configurable rotation increments (90°, 45°, 30°, 60°, or any custom angle). Key features:

• Configurable rotation increments (4-direction, 8-direction, or any custom angle)
• Cardinal direction rotation (backward compatible, convenience API)
• Isometric-aware rotation handling with complex transform support
• Snap-to-grid positioning after rotation
• Integration with existing GridPositioner2D and PlacementPositioning2DUtils
• Static methods for easy testing and reuse Usage Examples:
• 4-direction (RTS-style): rotate_node_clockwise(node, map, 90.0)
• 8-direction (isometric with diagonals): rotate_node_clockwise(node, map, 45.0)
• 6-direction (hex-style): rotate_node_clockwise(node, map, 60.0)
• 12-direction: rotate_node_clockwise(node, map, 30.0) Designed to work seamlessly with the existing Grid Building plugin architecture while providing specialized rotation functionality for grid-based gameplay.
