Struct UnrolledNavMeshGraphPortal
Intermediate struct used by the SSFA algorithm. It keeps track of the original 3D sides of the portals and the 2D projected ones. This information can then be used to reconstruct the intersection points of the straightened path in 3D.
Implements
Namespace: AnyPath.Graphs.NavMesh
Assembly: AnyPath.dll
Syntax
public struct UnrolledNavMeshGraphPortal : IUnrolledNavMeshGraphPortalRemarks
This method is not confined to word exclusively with the NavMesh. If your segments implement IUnrolledNavMeshGraphPortal you can unroll them into a plane and use it with GetSteerTargetPosition<T>(T, float3, ref int) or AppendCornersUnrolled<T>(NativeSlice<T>, NativeList<CornerAndNormal>, float)

Unroll<T>(NativeSlice<T>, NativeSlice<UnrolledNavMeshGraphPortal>)
Unrolls a path of portals into the XZ plane, allowing the SSFA algorithm to work on curved paths.
Declaration
public static void Unroll<T>(NativeSlice<T> path, NativeSlice<UnrolledNavMeshGraphPortal> destSegments) where T : unmanaged, IUnrolledNavMeshGraphPortalParameters
| Type | Name | Description |
|---|---|---|
| NativeSlice<T> | path | The path to process. |
| NativeSlice<UnrolledNavMeshGraphPortal> | destSegments | Output array of the portals. Needs to be of the same length as the path. |
Type Parameters
| Name | Description |
|---|---|
| T |
Remarks
This method is not confined to word exclusively with the NavMesh. If your segments implement IUnrolledNavMeshGraphPortal you can unroll them into a plane and use it with GetSteerTargetPosition<T>(T, float3, ref int) or AppendCornersUnrolled<T>(NativeSlice<T>, NativeList<CornerAndNormal>, float)
