Description

Singleton class to access the baked NavMesh.

The NavMesh is a class can be used to do spatial queries, like pathfinding and walkability tests, set the pathfinding cost for specific area types, and to tweak global behavior of pathfinding and avoidance.

In order to use the spatial queries, you need to first bake NavMesh for your Scene.

Static Variables

AllAreasArea mask constant that includes all NavMesh areas.
avoidancePredictionTimeDescribes how far in the future the agents predict collisions for avoidance.
pathfindingIterationsPerFrameThe maximum amount of nodes processed each frame in the asynchronous pathfinding process.

Static Functions

CalculatePathCalculate a path between two points and store the resulting path.
CalculateTriangulationCalculates triangulation of the current navmesh.
FindClosestEdgeLocate the closest NavMesh edge from a point on the NavMesh.
GetAreaCostGets the cost for path finding over geometry of the area type.
GetAreaFromNameReturns the area index for a named NavMesh area type.
RaycastTrace a line between two points on the NavMesh.
SamplePositionFinds the closest point on NavMesh within specified range.
SetAreaCostSets the cost for finding path over geometry of the area type on all agents.
