Function Documentation

BLV_GetFloorLevel()

float BLV_GetFloorLevel	(	const Vec3f &	pos,
		int	uSectorID,
		int *	pFaceID = nullptr
	)

Parameters

	pos	Actor's position.
	uSectorID	Actor's sector id.
[out]	pFaceID	Id of the closest floor/ceiling face for the provided position, or -1 if wrong sector is supplied or actor is out of bounds. Pass nullptr to ignore.

Returns

Float Z coordinate of the floor/ceiling face for the given position. If wrong sector is supplied or actor is out of bounds, -30000 is returned.

BLV_InitialiseDoors()

void BLV_InitialiseDoors

(

)

Initialises all door geometry into starting position on load.

BLV_ProcessPartyActions()

void BLV_ProcessPartyActions

)

BLV_UpdateDoorGeometry()

void BLV_UpdateDoorGeometry	(	BLVDoor *	door,
		int	distance
	)

Updates the geomtry position of the supplied door.

Parameters

door	Pointer to door to update.
distance	Distance the door is displaced. 0 is open, door->uMoveLength when closed.

BLV_UpdateDoors()

void BLV_UpdateDoors

(

)

Updates all door geometry into current position and plays sounds if moving.

CalcDistPointToLine()

int CalcDistPointToLine	(	int	x1,
		int	y1,
		int	x2,
		int	y2,
		int	x3,
		int	y3
	)

Check_LineOfSight()

bool Check_LineOfSight	(	const Vec3f &	target,
		const Vec3f &	from
	)

Parameters

target	Vec3f of position to check line of sight to
from	Vec3f of position to check line of sight from

Returns

True if line of sight clear to target

Check_LOS_Obscurred_Indoors()

bool Check_LOS_Obscurred_Indoors	(	const Vec3f &	target,
		const Vec3f &	from
	)

Parameters

target	Vec3f of position to check line of sight to
from	Vec3f of position to check line of sight from

Returns

True if line of sight obscurred by level geometery

Check_LOS_Obscurred_Outdoors_Bmodels()

bool Check_LOS_Obscurred_Outdoors_Bmodels	(	const Vec3f &	target,
		const Vec3f &	from
	)

Parameters

target	Vec3f of position to check line of sight to
from	Vec3f of position to check line of sight from

Returns

True if line of sight obscurred by outdoor models

GetApproximateIndoorFloorZ()

float GetApproximateIndoorFloorZ	(	const Vec3f &	pos,
		int *	pSectorID,
		int *	pFaceID = nullptr
	)

Original binary offset:

0x0047272C.

Same as GetIndoorFloorZ, but also tries jiggling the party around a bit if the collision point couldn't be found.

GetIndoorFloorZ

GetIndoorFloorZ()

float GetIndoorFloorZ	(	const Vec3f &	pos,
		int *	pSectorID,
		int *	pFaceID = nullptr
	)

Todo:

looks like this also works for ceilings, reflect in docs?

Parameters

	pos	Actor's position.
[in,out]	pSectorID	Actor's cached sector id. If the cached sector id is no longer valid (e.g. an actor has already moved to another sector), then the new sector id is returned in this output parameter. If the actor moves out of level bounds (this happens), then this parameter is set to 0.
[out]	pFaceID	Id of the floor face on which the actor is standing, or -1 if actor is outside the level boundaries. Pass nullptr to ignore.

Returns

Z coordinate for the floor at (X, Y), or -30000 if actor is outside the level boundaries.

loadAndPrepareBLV()

void loadAndPrepareBLV	(	MapId	mapid,
		bool	bLoading
