Class PlacementGridRotationUtils

Namespace
GridPlacement.GDScript
Assembly
MoonBark.GridPlacement.GDScript.dll

Grid-aware object rotation utilities for 2D grid-based games.\n\nProvides 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).\n\nKey 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 GBPositioning2DUtils - Static methods for easy testing and reuse\n\nUsage 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)\n\nDesigned to work seamlessly with the existing Grid Building plugin architecture while providing specialized rotation functionality for grid-based gameplay.
