 # Components for Runtime NavMesh Building
 
 Here we introduce four components for the navigation system:
 
-* __NavMeshSurface__ – for building and enabling a navmesh surface for one agent type.
-* __NavMeshModifier__ – affects the navmesh generation of navmesh area types, based on the transform hierarchy.
-* __NavMeshModifierVolume__ – affects the navmesh generation of navmesh area types, based on volume.
-* __NavMeshLink__ – connects same or different navmesh surfaces for one agent type.

 These components comprise the high level controls for building and using NavMeshes at runtime as well as edit time.

 Q: What's the deal with the 'DefaultExecutionOrder' attribute?  
-A: It gives a way of controlling the order of execution of scripts - specifically it allows us to build a navmesh before the
-(native) navmeshagent component is enabled.

 Q: What's the use of the new delegate 'NavMesh.onPreUpdate'?  
-A: It allows you to hook in to controlling the navmesh data and links set up before the navigation update loop is called on the native side.

 Q: Can I do moving NavMesh platforms?  
 A: No - new API is required for consistently moving platforms carrying agents.
@@ -59,4 +57,4 @@ Q: Is OffMeshLink now obsolete?
 A: No - you can still use OffMeshLink - however you'll find that NavMeshLink is more flexible and have less overhead.
 
 Q: What happened to HeightMesh and Auto Generated OffMeshLinks?  
-A: They're not supported in the new navmesh building feature. HeightMesh will be added at some point. Auto OffMeshLink generation will possibly be replaced with a solution that allows better control of placement.
