What it handles
The core workflow is already connected. Extend the parts your game needs instead of rebuilding the foundation.
Live ghost previews, snapping, rotation, move, and demolish.
Block bad placements with rules for space, collision, bounds, and your own game conditions.
One building workflow for 2D TileMapLayer grids and 3D GridMap builds.
Objects that face the right way with per-direction sprites.
Wall, edge, corner, and roof mounts plus ground support checks.
Paint and erase 3D cells, plus 2D brushes for line, rectangle, outline, and flood fill.
Place or paint many tiles and props in one stroke.
Build previews that stay readable without relying on red/green color alone.
Restore player builds through your game's save system.
Link costs, unlocks, and demolish refunds to your game's inventory and economy.
