Question I have to add a delay between disabling NavMeshAgent and setting rotation or it wont work?

I have a NavMeshAgent that moves around, and when he sees player he rotates towards player and shoots.

I tried implementing this like so:

Code (CSharp):

1. agent.enabled = false;
2. transform.rotation = GetDirection();

But for some reason 20% of the time, the rotation wouldnt get set properly.

So I tried making it a Coroutine:

Code (CSharp):

1. agent.enabled = false;
2.  
3. yield return new WaitForSeconds(0.1f);
4.  
5. transform.rotation = GetDirection();

Now it works every time, (yield return null did not work), what could be causing this? Rly dont want to use this ugly solution.

 

Been a while since I touched NavMesh stuff, but looking at the docs I see properties such as

isStopped

and

updateRotation

that might be a more direct means of allowing you to aim the agent. Maybe even just have the actual character as a child of the nav mesh agent and have it face in the right direction, being it the direction it's headed in, or towards a target.

As to why this happens, probably just a race condition. I don't imagine agents are updated every frame, so potentially even when you disable it, it may still be in control of the transform for a frame or two.

 

Yes adding the agent to a child game object like @spiney199 suggested would be the straightforward approach, if you don't want to deal with some (complex?) State just for rotation/movement coordination (IsMoving, IsRotating...)

 

I think he suggested adding the agent to the parent and having the mesh as a child, and controlling the mesh rotation, no?

 

ah yes maybe that would make things easier, so basically I rotate the child mesh (what you call character) so it’s visually facing the right dir, right?

 

When I made a game with agents I never let them have control of rotation. You often want them to look at the player or a collectable item. If there's nothing around to LookAt then make them look in the direction of travel, or scan/spin around looking for trouble.

 

That’s a nice idea actually. So u just disable agent rotation in Awake?

 

Yep!
