# 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.
|
||
|
||
Detailed information can be found in the [Documentation](Documentation~).

# FAQ
|
||
|
||
Q: Can I bake a NavMesh at runtime?
|
||
A: Yes.
|
||
|
||
Q: Can I use NavMesh'es for more than one agent size?
|
||
A: Yes.
|
||
|
||
Q: Can I put a NavMesh in a prefab?
|
||
A: Yes - with some limitations.
|
||
|
||
Q: How do I connect two NavMesh surfaces?
|
||
A: Use the NavMeshLink to connect the two sides.
|
||
|
||
Q: How do I query the NavMesh for one specific size of agent?
|
||
A: Use the NavMeshQuery filter when querying the NavMesh.
|
||
|
||
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.
|
||
|
||
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.
