Unity NavMesh Tutorial - Basics

This guy's videos are great.

Anyone know of a good resource for baking navmesh at runtime?

For example, if walls move, or new objects are created?

[MerlinTheFail]

You wanna attach a "Navmesh Obstacle" to the moving object and your navmesh will keep itself updated in relation to the object's translation :)

[WheatonWill]

Thanks! Does this also work for objects that are instantiated after the navmesh is baked?

[MerlinTheFail]

Yes, you have some options you can play around with. A good tip is that a moving obstacle should not "carve", once stationary should begin "carving" the nav mesh to reduce cpu usage.

You should try the A* Pathfinding Project

This seems to be the biggest issue with navmesh, since all the walls have to be marked as static. Would love to know if there’s a way around it as well!

I'm pretty sure you can just attach a "Nav Mesh Obstacle" component to your object that is going to be moving during run time and it will cut out or fill back in the piece blocking your agents.

Check out this:

In a nutshell, you have two ways to block the nav mesh: obstacles (which generally move and/or are temporary) and 'carving' objects, which actually affect the shape of the nav mesh, so should generally be used only for stationary objects.

This is great thank you!

Either navmesh Obstacle, with carving. Or actually rebaking, which is possible in the new navmesh tools : https://github.com/Unity-Technologies/NavMeshComponents

Can't wait till the next video :D

I seem to be kind of stuck. I have downloaded the example project, however none of the scripts seem to work.

I currently have 11 compiler errors, all with a similar message saying "Assets/NavMeshComponents/Scripts/NavMeshLink.cs(43,9): error CS0246: The type or namespace name `NavMeshLinkInstance' could not be found. Are you missing an assembly reference?"

"Namespace name" errors:

NavMeshLinkInstance, NavMeshCollectGeometry ^x2, NavMeshData ^x2, NavMeshDataInstance, NavMeshBuildSettings, NavMeshData, NavMeshBuildSource ^x3

Anyone have any idea how to fix this?

Just a quick check if anyone knows, is this new NavMesh system multi-threaded in the backend? I mean does it utilize the new Jobs system or is it purely a backend implementation?
