MapFogFilterFlags() [1/2]

int MapFogFilterFlags	(	CPlayer &	player,
		const unsigned int	index,
		int	mask
	)

Find out what the tile flags are a tile is covered by fog

Parameters

player	player who is doing operation
index	map location
mask	input mask to filter

Returns

Filtered mask after taking fog into account

MapFogFilterFlags() [2/2]

int MapFogFilterFlags	(	CPlayer &	player,
		const Vec2i &	pos,
		int	mask
	)

Filter map flags through fog.

MapMarkTileDetectCloak() [1/2]

void MapMarkTileDetectCloak	(	const CPlayer &	player,
		const unsigned int	index
	)

Mark a tile for cloak detection.

Parameters

player	Player to mark sight.
index	Tile to mark.

MapMarkTileDetectCloak() [2/2]

void MapMarkTileDetectCloak	(	const CPlayer &	player,
		const Vec2i &	pos
	)

MapMarkTileSight() [1/2]

void MapMarkTileSight	(	const CPlayer &	player,
		const unsigned int	index
	)

Mark a tile's sight. (Explore and make visible.)

Parameters

player	Player to mark sight.
index	tile to mark.

MapMarkTileSight() [2/2]

void MapMarkTileSight	(	const CPlayer &	player,
		const Vec2i &	pos
	)

MapSight()

void MapSight	(	const CPlayer &	player,
		const CUnit &	unit,
		const Vec2i &	pos,
		int	w,
		int	h,
		int	range,
		MapMarkerFunc *	marker
	)

Mark sight changes.

Parameters

player	player to mark the sight for (not unit owner)
pos	location to mark
w	width to mark, in square
h	height to mark, in square
range	Radius to mark.
marker	Function to mark or unmark sight

Parameters

player	Player to mark sight.
index	tile to mark.

Assert(*v != 0); This could happen if shadow caster type of field of view is enabled, because of multiple calls for tiles in vertical/horizontal/diagonal lines

MapUnmarkTileDetectCloak() [2/2]

void MapUnmarkTileDetectCloak	(	const CPlayer &	player,
		const Vec2i &	pos
	)

MapUnmarkTileSight() [1/2]

void MapUnmarkTileSight	(	const CPlayer &	player,
		const unsigned int	index
	)

Unmark a tile's sight. (Explore and make visible.)

Parameters

player	Player to mark sight.
indexx	tile to mark.

TODO: change ThisPlayer to currently rendered player/players #RenderTargets

MapUnmarkTileSight() [2/2]

void MapUnmarkTileSight	(	const CPlayer &	player,
		const Vec2i &	pos
	)
