awesome!
yes thats what i need. i have golems in game and they are big
Thanks for great guide! I always had a problem about that. For example, i have some customers that can come from many side from our bakery. But I dont want to allow my player to leave our bakery, They are both moved by navmesh component and they use same navmesh surface which is the total area.. Even if i bake for different navmesh surfaces, (which looks for children mesh), my player can still be able to walk around customer's areas. Does this NavmeshQuery helps me to solve that? How would you achieve something that AgentA can walk in AreaB but AgentB shouldnt walk in AreaB? I would be really appreaciated if you explain how would you approach that. I have tried many solutions but ended up using obstacles which needed to reposition my customers.. So customers would only walk where player walks. :(
For that use case I would bake 2 separate NavMeshes using 2 different NavMeshAgent types even if their configuration is the same. For the customer areas you can put them on their own layer and exclude that layer from the Player NavMesh bake. You could also attach NavMeshModifiers to the walkable areas for the customers and exclude them from the bake of the Player NavMeshSurface.
Depending on your level design, you can change the NavMeshSurface bake type to Volume, much like how the chickens are done here, to only allow them to walk within a small area. This requires you have a rectangular area for the player though. The other options will work reagardless of the level design.
I did exactly what you have said with modifiers, selecting agent type and excluding others but something didnt go right. Can you try this in your free time if its working successfully with modifiers? I have created navmesh surface and baking children. and i selected customer area, and add navmesh modifier, override area and select type of customer. And set customers agent type in navmesh agent and i have excluded player inside agent and modifier. But ended up customers having error of activd agent surface couldnt find or similar when a navmesh cant find a navmesh surface in ground. I wonder what might went wrong. If i bake them all without modifiers, evertyting works but i cant prevent player walking through customers area
@@TheKr0ckeR Have the same problems with Navmesh Modifier.
If I read that right, I think you configured it backwards. You want to exclude the customer area for the player walking on it. So on the outside you would have modifiers saying exclude for player.
How to specify specific custom "NavMeshArea" in QueryFilter? Not "Walkable" \ allTypes
You can use the helper NavMesh.GetAreaFromName
for other area types. docs.unity3d.com/ScriptReference/AI.NavMesh.GetAreaFromName.html
I tried this (NavMesh.GetAreaFromName). However, it didn't work for me due to the "Walkable" in the scene. And it was always taken as priority by default, ignoring the mask. When I replaced Walkable with custom area, the taco option worked!
