#include guard	P_SLOPES_H__

This header file contains prototypes for various setup and utility functions for slopes and slope physics.

Function name	Return type	Params	Defined in	Description
P_CalculateSlopeNormal	void	pslope_t *slope	p_slopes.c	Recalculates the normal of the slope.
P_ResetDynamicSlopes	void	none	p_slopes.c	Resets the slopes list, handles spawning the current map's slopes. Called by P_SetupLevel.
P_RunDynamicSlopes	void	none	p_slopes.c	Recalculates the z-delta and angle of dynamic slopes if needed. Called each tic by P_UpdateSpecials.
P_SpawnSlope_Line	void	int linenum	p_slopes.c	Creates one or more slopes based on the given linedef type and front/back sectors.
P_CopySectorSlope	void	line_t *line	p_slopes.c	Searches through the linedef's tagged sectors and copies the first found slope (for floor and/or ceiling, depending on the linedef special) to the linedef's front sector.
P_SlopeById	pslope_t *	UINT16 id	p_slopes.c	Looks in the slope list for a slope with a specified ID. Mostly useful for netgame synchronisation.
P_GetZAt	fixed_t	pslope_t *slope, fixed_t x, fixed_t y	p_slopes.c	Returns the height of the sloped plane at (x, y) as a fixed_t integer.
P_QuantizeMomentumToSlope	void	vector3_t *momentum, pslope_t *slope	p_slopes.c	When given a vector, rotates it and aligns it to a slope.
P_ReverseQuantizeMomentumToSlope	void	vector3_t *momentum, pslope_t *slope	p_slopes.c	When given a vector, rotates it and aligns it to a flat surface (from being relative to a given slope).
P_SlopeLaunch	void	mobj_t *mo	p_slopes.c	Handles slope ejection for objects.
P_HandleSlopeLanding	void	mobj_t *thing, pslope_t *slope	p_slopes.c	Function to help handle landing on slopes.
P_ButteredSlope	void	mobj_t *mo	p_slopes.c	Handles sliding down slopes.
