updatePosition doesn't seem to work properly in unity 5

I have a navmeshagent which is used to power mecanim rootmotion through desired velocity. to achieve this i had updatePosition = false. this way i could feed the desired velocity to rootmotion. this worked in unity 4.

in unity 5, the navmeshagent does not stay synced with the gameobject's transform correctly. instead in the scene view i can see the navmeshagent's collider moving to the desired position separately. the navmeshagent's collider shouldn't move at all if updatePosition is false. when this moves out of sync, it throws all the calculations off and the entity assumes it is at the position because the navmeshagent is there.

 

What exactly are you doing?
You take the velocity from the NavMeshAgent and pass that to Mecanim. Do you modify the position yourselves as well or do you pass the control for that to Mecanim?

No - it means that the simulated agent position is decoupled from the Transform position of the game object.
(see http://docs.unity3d.com/ScriptReference/NavMeshAgent-updatePosition.html)

Did you enable root motion on the Animator component ?

 

root motion is controlled by a script. i take in the root motion and modify it based on my needs through OnAnimatorMove() the vector is then used to move a character controller. maybe this is strange to do, but it used to work in 4.

how would i keep the simulated position the same as the actual gameobject's position so that i can move the object along a path correctly?

 

i'm not sure if this changed recently but i added navAgent.nextPosition = transform.position and it fixed my issue.

 

Here's a part of the manual that sounds relevant to your use-case: http://docs.unity3d.com/Manual/nav-CouplingAnimationAndNavigation.html
