Problem with creating an vehicle.

[gro0wl]

Hey! Can you help me with my error?

I tried to create vehicle on vehicleFramework, but after my hourly work i see this error in BeplnEx log

[Error  : Unity Log] NullReferenceException: Object reference not set to an instance of an object
Stack trace:

I think problem with MainPatcher.cs, but i can't find it :/

Hi, it looks to me like your GetAssets method might be the problem. I think it is not correctly retrieving your model prefab. For that reason, I think vehicle.model is null when Register is invoked

Submersible nowcub = vehicle.model.EnsureComponent<vehicle>() as Submersible;

causing the error in the log:

NullReferenceException: Object reference not set to an instance of an object Stack trace: Radical.EnsureComponent

I think the fix should be in here:

            System.Object[] arr = myLoadedAssetBundle.LoadAllAssets();
            foreach (System.Object obj in arr)
            {
                if (obj.ToString().Contains("MY_SPRITE_ATLAS_NAME"))
                {
                    model = (GameObject)obj;
                }
            }

Perhaps like this:

            System.Object[] arr = myLoadedAssetBundle.LoadAllAssets();
            foreach (System.Object obj in arr)
            {
                if (obj.ToString().Contains("MY_CORRECTED_PREFAB_NAME"))
                {
                    VehicleFramework.Logger.Log("Found the prefab!");
                    model = (GameObject)obj;
                }
            }

Thank You! But i have another error (0-0)

[Error  :VehicleFramework] vehicle:  A null VehicleBattery.BatterySlot was provided. There would be no way to access this battery.
[Error  :VehicleFramework] Invalid Submersible Registration for the vehicle. Next.

But the battery slots are correctly setted up (probably)
Class with battaries

        public override List<VehicleBattery> Batteries
        {
            get
            {
                var list = new List<VehicleFramework.VehicleParts.VehicleBattery>();

                VehicleFramework.VehicleParts.VehicleBattery v61 = new VehicleFramework.VehicleParts.VehicleBattery();
                v61.BatterySlot = transform.Find("Battaries/Battary1").gameObject;
                list.Add(v61);

                VehicleFramework.VehicleParts.VehicleBattery v62 = new VehicleFramework.VehicleParts.VehicleBattery();
                v61.BatterySlot = transform.Find("Battaries/Battary2").gameObject;
                list.Add(v62);



                return list;
            }


        }

Hi, it looks like a simple fix. Sorry for the delayed reply. You sent this:

public override List<VehicleBattery> Batteries
{
    get
    {
        var list = new List<VehicleFramework.VehicleParts.VehicleBattery>();

        VehicleFramework.VehicleParts.VehicleBattery v61 = new VehicleFramework.VehicleParts.VehicleBattery();
        v61.BatterySlot = transform.Find("Battaries/Battary1").gameObject;
        list.Add(v61);

        VehicleFramework.VehicleParts.VehicleBattery v62 = new VehicleFramework.VehicleParts.VehicleBattery();
        v61.BatterySlot = transform.Find("Battaries/Battary2").gameObject; // error is here!
        list.Add(v62);

        return list;
    }
}

So I think you should change this to reference the right VehicleBattery (v62 instead of v61).

v61.BatterySlot = transform.Find("Battaries/Battary2").gameObject;

Make it look like this instead:

v62.BatterySlot = transform.Find("Battaries/Battary2").gameObject;

That's an easy mistake to make, and I've made it many times :-)

Thank you (when i be in home i try this.)
