NullReferenceException in Steering.cs about unitysteer HOT 3 CLOSED

Hi,

I'm not sure what you mean by this:

I've really studied your code and I'm not sure why calling the base to Start, and I even tried calling the base to Awake, didn't find the component before CalculateForce tried asking for it.

Do you mean that there was a Vehicle instantiated, and that the Awake for the Steering was being called, but for some reason _vehicle was still null the first time CalculateForce was invoked?

from unitysteer.

If by instantiated you mean via the Autonomous vehicle component I put on
my game object, then yes, precisely.

I guess I should that I'm not using UnitySteer in it's out of the box
state, but this is one part that I didn't touch. If you're not having the
same error, I'd at least check into whether or not you're getting any sort
of null exception before it successfully grabs the component.

Out of curiosity, could what order I attach the scripts to the game object
matter?

It shouldn't, unless you're instantiating them via code at run-time. The queue that ticks the vehicles is created on TickedVehicle.OnEnable, which means that even an over-eager tick should happen after all Awakes have been called.

If you're instantiating them manually, and instantiate the Vehicle after the Steering, then I suppose it is possible.

I'm afraid I haven't seen this issue, and I do use it daily (it's what powers the characters on Hairy Tales). Do let me know if you manage to narrow it down!
