Storing and Updating NavMesh at runtime

[edit] see below:

 

Hi there,

After reading everything I can find and looking through the example project, I've clarified some things but am lost on others regarding the new NavMesh tools.

For context, my project is tile-based and needs the NavMesh to be baked at runtime, and occasionally updated when immobile objects are created or destroyed.

I have been able to bake the navmesh at runtime using NavMeshBuilder.BuildNavMesh(); and tagging the objects using 'navigation static'. What I have no idea how to do is to store the NavMesh so I can update or remove it. I don't quite understand how unity handles NavMesh data and the documentation just doesn't have enough examples for me to understand how everything is stored.

Any help on this would be greatly appreciated!

Thanks,

-Chris

 

The navmesh data is stored in the https://docs.unity3d.com/ScriptReference/AI.NavMeshData.html object. You can keep a reference to these object in scripts at runtime - e.g. for updating.
At edit time the data can be saved to disk using : https://docs.unity3d.com/ScriptReference/AssetDatabase.CreateAsset.html
