AI don't avoid obstacles with collider [Solved]

[wexam]

Hi!

I don't understand why ai do not avoid colliders,
only at the edge of a floor?
this won't work in a landscape scene.

All my ai, companion ai is stuck everywhere!
or are this behavior not implemented in the fsm ai template?
Layers are in default on colliders.

Here is a screenshot from Invector fsm ai spawner Scene,
ai is stuck on the collider




Ai avoiding the edge without collider


Or have i missed something here ?

Obstable avoidance is done via Layers, make sure you assign the layer of your obstacle in the AI Controller inspector > Detection > Obstacles Layer

You also need to limit the navmesh area to within your colliders, otherwise, the agent could get a destination to a point outside our colliders

Yes i can't see this detection layer have an effect on the ai
you still have to bake every obstacle with navmesh obstacle right?

[Invector]

Yes, I think the NavMesh needs the mesh renderer visible in order to bake the obstacles, you can turn on the mesh renderer, bake, and turn off again

Thank you sir, i think this would be a good addition to your ai template to actually have an avoidance behavior.

The Unity Navmesh does provide a pretty solid obstacle avoidance, you can even have paths with priority. 

For ex: A Bridge and a lava floor, the first priority will be the bridge but if the bridge is broken the AI will run through the lava which is the secondary in the priority order.
