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.

정적 변수

AllAreasArea mask constant that includes all NavMesh areas.
avoidancePredictionTimeDescribes how far in the future the agents predict collisions for avoidance.
onPreUpdateSet a function to be called before the NavMesh is updated during the frame update execution.
pathfindingIterationsPerFrameThe maximum amount of nodes processed each frame in the asynchronous pathfinding process.

정적 함수

AddLinkAdds a link to the NavMesh. The link is described by the NavMeshLinkData struct.
AddNavMeshDataAdds the specified NavMeshData to the game.
CalculatePathCalculate a path between two points and store the resulting path.
CalculateTriangulationCalculates triangulation of the current navmesh.
CreateSettingsCreates and returns a new entry of NavMesh build settings available for runtime NavMesh building.
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.
GetSettingsByIDReturns an existing entry of NavMesh build settings.
GetSettingsByIndexReturns an existing entry of NavMesh build settings by its ordered index.
GetSettingsCountReturns the number of registered NavMesh build settings.
GetSettingsNameFromIDReturns the name associated with the NavMesh build settings matching the provided agent type ID.
RaycastTrace a line between two points on the NavMesh.
RemoveAllNavMeshDataRemoves all NavMesh surfaces and links from the game.
RemoveLinkRemoves a link from the NavMesh.
RemoveNavMeshDataRemoves the specified NavMeshDataInstance from the game, making it unavailable for agents and queries.
RemoveSettingsRemoves the build settings matching the agent type ID.
SamplePositionFinds the closest point on NavMesh within specified range.
SetAreaCostSets the cost for finding path over geometry of the area type on all agents.


OnNavMeshPreUpdateA delegate which can be used to register callback methods to be invoked before the NavMesh system updates.
