public readonly int GetGeneratedLinksCount(NavMeshDataInstance navMeshInstance)
Parameters
The NavMeshDataInstance to count the baked links for.
Returns
Type | Description |
|---|---|
| int | The total number of navigation links baked into the specified NavMeshDataInstance. |
Remarks
Use the returned count to size the buffer that you pass to NavWorld.GetGeneratedLinkNodes, so that a single call retrieves all the baked links. The count covers only the links baked into the NavMeshData itself, not the links added separately to the navigation system at runtime.
