Modifier which smooths the path. More...
Modifier which smooths the path.
This modifier can smooth a path by either moving the points closer together (Simple) or using Bezier curves (Bezier).
Attach this component to the same GameObject as a Seeker component.
This component will hook in to the Seeker's path postprocessing system and will post process any paths it searches for. Take a look at the Modifier Priorities settings on the Seeker component to determine where in the process this modifier should process the path.
Several smoothing types are available, here follows a list of them and a short description of what they do, and how they work. But the best way is really to experiment with them yourself.
Public Types

List<Vector3> SmoothBezier  (  List< Vector3 >  path  )

List<Vector3> SmoothSimple  (  List< Vector3 >  path  ) 
float bezierTangentLength = 0.4F 
Length factor of the bezier curves' tangents'.
float factor = 0.1F 
Roundness factor used for CurvedNonuniform.
int iterations = 2 
Number of times to apply smoothing.
float maxSegmentLength = 2F 
The length of the segments in the smoothed path when using uniformLength.
A high value yields rough paths and low value yields very smooth paths, but is slower
float offset = 0.2F 
Offset to apply in each smoothing iteration when using Offset Simple.
SmoothType smoothType = SmoothType.Simple 
Type of smoothing to use.
float strength = 0.5F 
Determines how much smoothing to apply in each smooth iteration.
0.5 usually produces the nicest looking curves.
int subdivisions = 2 
Number of times to subdivide when not using a uniform length.
bool uniformLength = true 
Toggle to divide all lines in equal length segments.
