RaycastModifier Class Reference

Simplifies a path using raycasting. More...

Detailed Description

Simplifies a path using raycasting.

This modifier will try to remove as many nodes as possible from the path using raycasting (linecasting) to validate the node removal. Either graph raycasts or Physics.Raycast

Member Function Documentation

override void Apply ( Path  p, ModifierData  source  )

virtual

Main Post-Processing function.

Implements MonoModifier.

bool ValidateLine	(	GraphNode	n1,
		GraphNode	n2,
		Vector3	v1,
		Vector3	v2
	)

Check if a straight path between v1 and v2 is valid.

Member Data Documentation

int iterations = 2

LayerMask mask = -1

List<Vector3> nodes

staticprivate

To avoid too many memory allocations.

An array is kept between the checks and filled in with the positions instead of allocating a new one every time.

Vector3 raycastOffset = Vector3.zero

bool subdivideEveryIter

bool thickRaycast

float thickRaycastRadius

bool useGraphRaycasting

Use raycasting on the graphs.

Only currently works with GridGraph and NavmeshGraph and RecastGraph.

A* Pro Feature:

This is an A* Pathfinding Project Pro feature only. This function/class/variable might not exist in the Free version of the A* Pathfinding Project or the functionality might be limited
