Function Documentation

debug_surface_list_info()

void debug_surface_list_info	(	f32	xPos,
		f32	zPos
	)

Print the area,number of walls, how many times they were called, and some allocation information.

f32_find_wall_collision()

s32 f32_find_wall_collision	(	f32 *	xPtr,
		f32 *	yPtr,
		f32 *	zPtr,
		f32	offsetY,
		f32	radius
	)

Formats the position and wall search for find_wall_collisions.

find_ceil()

f32 find_ceil	(	f32	posX,
		f32	posY,
		f32	posZ,
		struct Surface **	pceil
	)

Find the lowest ceiling above a given position and return the height.

(Parallel Universes) Because position is casted to an s16, reaching higher

find_floor()

f32 find_floor	(	f32	xPos,
		f32	yPos,
		f32	zPos,
		struct Surface **	pfloor
	)

Find the highest floor under a given position and return the height.

(Parallel Universes) Because position is casted to an s16, reaching higher

(BBH Crash) Most NULL checking is done by checking the height of the floor returned

find_floor_height()

f32 find_floor_height	(	f32	x,
		f32	y,
		f32	z
	)

Find the height of the highest floor below a point.

find_floor_height_and_data()

f32 find_floor_height_and_data	(	f32	xPos,
		f32	yPos,
		f32	zPos,
		struct FloorGeometry **	floorGeo
	)

Return the floor height underneath (xPos, yPos, zPos) and populate floorGeo with data about the floor's normal vector and origin offset.

Also update sFloorGeo.

find_poison_gas_level()

f32 find_poison_gas_level	(	f32	x,
		f32	z
	)

Finds the height of the poison gas (used only in HMC) at a given location.

find_wall_collisions()

s32 find_wall_collisions

(

struct WallCollisionData *

colData

)

Find wall collisions and receive their push.

find_water_level()

f32 find_water_level	(	f32	x,
		f32	z
	)

Finds the height of water at a given location.
