[1.1.0-pre.2] - 2022-08-09

Changed

  • The Dungeon scene included in the package samples now uses tile prefabs that contain a NavMeshSurface component instead of the NavMeshPrefabInstance script.
  • The Drop Plank scene included in the package samples now has a NavMeshSurface component and the NavMeshSurfaceUpdater script on the geometry, as well as the DynamicNavMeshObject script on the Plank prefab for dynamically updating the NavMesh when new Planks are instantiated.
  • The offset when instantiating Planks in the Drop Plank scene has been reduced.
  • The Sliding Window Infinite and the Sliding Window Terrain scenes included in the package samples now use the NavMeshSurfaceVolumeUpdater script instead of the LocalNavMeshBuilder and NavMeshSourceTag scripts for dynamically updating the NavMesh.
  • The Modify Mesh scene included in the package samples now uses a NavMeshSurface component on the Mesh Tool for dynamically updating the NavMesh instead of the LocalNavMeshBuilder and NavMeshSourceTag scripts. The MeshTool script now uses the Update() method of NavMeshSurface for updating the NavMesh whenever the mesh is modified.

Fixed

  • Missing agent type references in the samples.

Removed

  • The NavMeshPrefabInstance and NavMeshPrefabInstanceEditor scripts from the package samples were removed.
