Member Enumeration Documentation

enum Exactness

Sets where the start and end points of a path should be placed.

Enumerator:

SnapToNode	The point is snapped to the first/last node in the path.
Original	The point is set to the exact point which was passed when calling the pathfinding.
Interpolate	The point is set to the closest point on the line between either the two first points or the two last points. Usually you will want to use the NodeConnection mode instead since that is usually the behaviour that you really want.
ClosestOnNode	The point is set to the closest point on the node. Note that for some node types (point nodes) the "closest point" is the node's position which makes this identical to Exactness.SnapToNode
NodeConnection	The point is set to the closest point on one of the connections from the start/end node.

Member Function Documentation

override void Apply ( Path  path )

virtual

Main Post-Processing function.

Implements PathModifier.

Vector3 GetClampedPoint	(	Vector3	from,
		Vector3	to,
		GraphNode	hint
	)

Vector3 Snap ( ABPath  path, Exactness  mode, bool  start, out bool  forceAddPoint  )

Member Data Documentation

bool addPoints

Add points to the path instead of replacing them.

System.Func<Vector3> adjustStartPoint

Will be called when a path is processed.

The value which is returned will be used as the start point of the path and potentially clamped depending on the value of the exactStartPoint field. Only used for the Original, Interpolate and NodeConnection modes.
