struct	eve::map::DualGridOptions
	Dual-grid autotile (Oskar Stålberg style). 更多...

命名空间
namespace	eve

namespace	eve::map
	放置世界：格子占用（多通道）+ 地形语义 + 已放置建筑实例。行为由 PlacementSystem 提供；本类暴露便于脚本绑定的薄封装方法。坐标换算统一走 eve::grid（支持 rectangle / iso / staggered / hex 与 XY/XZ 平面轴）。

函数
int	eve::map::dualGridMaskFromCorners (bool tl, bool tr, bool bl, bool br)
	Pack four corner occupancy bits: TL=1, TR=2, BL=4, BR=8.

int	eve::map::dualGridDefaultFrame (int mask)
	Default 4x4 atlas frame index for mask 0..15. -1 means draw nothing. Matches the SpriteCook / common dual-grid sheet layout.

const std::array< int, 16 > &	eve::map::dualGridDefaultFrameTable ()
	Copy of the default frame table (16 entries).

void	eve::map::dualGridHalfOffset (const TileLayer::Config &cfg, float &offX, float &offY)
	Half-step origin delta for the display layer (added to logic origin). Orthogonal: (-tileW/2, -tileH/2) Isometric: (0, -tileH/2) — equivalent to logic coords (tx-0.5, ty-0.5) Staggered/Hex Y: (-tileW/2, -pitchY/2) Staggered/Hex X: (-pitchX/2, -tileH/2)

bool	eve::map::dualGridLogicFilled (TileLayer &logic, int tx, int ty, int filledGid)
	Whether logic cell (tx,ty) is filled under options. Out of bounds → false.

int	eve::map::dualGridMaskAt (TileLayer &logic, int dx, int dy, int filledGid=0)
	4-bit corner mask for display cell (dx,dy) on a (logicW+1)×(logicH+1) grid. Samples logic (dx-1,dy-1), (dx,dy-1), (dx-1,dy), (dx,dy) in index space (orientation-independent topology).

bool	eve::map::resolveDualGrid (TileLayer logic, TileLayer display, const DualGridOptions &opts, std::string *error=nullptr)
	Resolve logic → display dual-grid tiles. Resizes display to (logicW+1)×(logicH+1), copies tile size / orientation / stagger / hex from logic, optionally applies projection-correct half-step origin offset, writes GIDs. Returns false and sets error on invalid args.

bool	eve::map::resolveDualGrid (TileLayer logic, TileLayer display, std::string *error=nullptr)
	Convenience: any non-zero filled, default frame table, half offset, hide logic.
