Runtime Navigation
Dungeon Architect can generate dungeons at runtime so you get a new dungeon every time you play
This section shows you how to generate a navigation mesh on these runtime generated dungeons so the NPCs can move around
This section is releavant for dungeon types that use a theme file (e.g. Grid Builder, Grid Flow builder, City builder etc)
Setup Dungeon Game Object
Select the Dungeon game object and make sure you have the `Dungeon component in it. If not add one
Make sure Enable Runtime Navigation is checked
Build Runtime Dungeon
Setup your scene so this dungeon gets built at runtime as discussed in the section Runtime Dungeons section and hit Play
This will build your dungeon but won't build the navigation mesh, since we haven't specified the meshes that would contribute to the navmesh generation
To confirm this, do the following:
Open the navigation panel from the main menu (
Window > AI > Navigation)
Play your game and switch to the Scene view. Now focus on the Navigation panel, you won't see a nav mesh generated
Setup Theme File
When we spawn prefabs from the theme editor, we'll need to set a flag on all the prefabs that would contribute to the navigation mesh generation
Open the theme that your dungeon uses
Select the Ground prefab node and inspect the properties
Make sure Affects Navigation is set. Do this for all the static prefabs (Walls, doors, fence etc)
Now run the game and you'll see the navigation mesh
You don't want holes under dynamic objects like NPCs, Keys etc
Make sure you've not set them to affect the nav mesh generation
