Detailed Description

Pathfinder goal.

The goal can be either a point, a circle, or a square (rectangle). For circles/squares, any point inside the shape is considered to be part of the goal. Also, it can be an 'inverted' circle/square, where any point outside the shape is part of the goal.

fixed PathGoal::DistanceToPoint

(

CFixedVector2D

pos

)

const

Returns the minimum distance from the point with the given pos to any point on the outline of the goal shape.

bool PathGoal::NavcellContainsGoal	(	int	i,
		int	j
	)		const

Returns true if the given navcell contains a part of the goal area.

bool PathGoal::NavcellRectContainsGoal	(	int	i0,
		int	j0,
		int	i1,
		int	j1,
		int *	i,
		int *	j
	)		const

Returns true if any navcell (i, j) where min(i0,i1) <= i <= max(i0,i1) min(j0,j1) <= j <= max(j0,j1), contains a part of the goal area.

If so, arguments i and j (if not NULL) are set to the goal navcell nearest to (i0, j0), assuming the rect has either width or height = 1.

CFixedVector2D PathGoal::NearestPointOnGoal

(

CFixedVector2D

pos

)

const

Returns the coordinates of the point on the goal that is closest to pos in a straight line.

bool PathGoal::RectContainsGoal	(	entity_pos_t	x0,
		entity_pos_t	z0,
		entity_pos_t	x1,
		entity_pos_t	z1
	)		const

Returns true if the rectangle defined by (x0,z0)-(x1,z1) (inclusive) contains a part of the goal area.
