Error with IA

[dav]

I usually get this error once the IA is moving:

navmeshagent.velocity assign attempt for 'IA _Character_Goblin_Pistol (5)' is not valid. Input velocity is { NaN, NaN, NaN }.
UnityEngine.AI.NavMeshAgent:set_velocity(Vector3)
Invector.vCharacterController.AI.vControlAI:OnAnimatorMove() (at Assets/Invector-AIController (Beta)/Scripts/AI/AI Controllers/vControlAI.cs:213)


I don't post the code because Invector's privacy terms, but is in vcontrolAI.cs:

protected override void OnAnimatorMove()

line:

navMeshAgent.velocity = ((animator.deltaPosition) / Time.deltaTime) * Mathf.Clamp(remainingDistanceWithoutAgent - stopingDistance, 0, 1f);

Any idea? Thanks

Hmm strange, does this happens as soon as you hit play or sometimes? Did you bake the navmesh?

This was happening to me, when i pause the game (delta time is 0) to show pause menu. During that time, until delta time is not 0 this error is spamming my console.

I think i disabled AI during pause menu to fix this.

Pretty sure it's a division by zero error if NaN is around

[uberwiggett]

yes this pops up on start for me too, it's a calculation error like tharindu said, it occurs when the character isn't able to move (ie when the startup occurs or during a pause) and tries to do a calculation, it does not break anything though.

I have the same problem :(

Oh we used to have this issue with the old AI as well, it's pretty simplae actually...
Just add a if(Time.time <= 0) return; or something like that in the AnimatorMove method.

I will take a look better tomorrow and post a quickfix here ;)
Now it's time to zzzZZZzZzZzzZzZ

Hi Invector,

I am receiving the same error when pausing my game. I am using the The Shooter Template + FSM AI Template + Adventure Creator Integration.

In the Adventure Creator Integration part of the forums, in August 2017, you have advised with:


Open the v_AIAnimator script and replace line 61 to



if (Time.timeScale <= 0.1f) return

Then advised with:

I remember that someone already ask about this before, did a about navmeshagent.velocity and find the anwser here in the forum, just replace line 62 to this:



if (agent.enabled && !agent.isOnOffMeshLink && agent.updatePosition && Time.deltaTime != 0)

I have tried the three suggestions and experimented a bit more but it does not seem to be working.

Any advice please?

My error is:

navmeshagent.velocity assign attempt for 'AI - Arena_Red_Shooter (1)' is not valid. Input velocity is { NaN, NaN, NaN }.
UnityEngine.AI.NavMeshAgent:set_velocity(Vector3)

Thank you very much.

I did the fix yesterday, it's pretty simple... just add the verification inside the method OnAnimatorMove of the vControlAI

if(Time.deltaTime == 0) return;
