Hey guys, I hate to bug you again but I’m on the edge here. I have no idea whether I got super stupid in last several years or is there something seriously wrong here and it’s not on me.

I’ve encountered so many problems with the code thus far that you wouldn’t believe it. Yesterday I gave a shot to the „Assasination Plugin” tutorial by Albo1125. (https://www.youtube.com/watch?v=lZUAXBYRaE4&t=185s)

Despite of using literally the same code my plugin crashes. It’s not the first time things go down that road. What the f… is going on here? Did I miss something?  I'm totally helpless.

1) I added the following references:

LSPD First Response
RAGENativeUI
RagePluginHookSDK
System.Windows.Forms (for pressing the key)

2) The code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Rage;

[assembly: Rage.Attributes.Plugin("wtf", Description = "B", Author = "Pawel")]
namespace wtf
{
    public static class EntryPoint
    {

        public static void Main()
        {
            GameFiber.StartNew(delegate
            {
                Game.DisplayNotification("To ostatnia wtyczka");



                while (true)
                {
                    GameFiber.Yield();
                    if (Game.IsKeyDown(System.Windows.Forms.Keys.Enter))
                    {
                        break;
                    }
                }
                Ped RogueOfficer = new Ped(Game.LocalPlayer.Character.GetOffsetPositionFront(10f));
                Vehicle RogueOfficerCar = new Vehicle("POLICE4", Game.LocalPlayer.Character.GetOffsetPositionFront(15f));

                RogueOfficer.BlockPermanentEvents = true;
                RogueOfficer.IsPersistent = true;
                RogueOfficerCar.IsPersistent = true;

                RogueOfficer.Tasks.EnterVehicle(RogueOfficerCar, 10000, -1).WaitForCompletion(3000);

                RogueOfficer.Tasks.DriveToPosition(Game.LocalPlayer.Character.Position, 15f, VehicleDrivingFlags.Emergency).WaitForCompletion(6000);
                RogueOfficer.Tasks.LeaveVehicle(LeaveVehicleFlags.None);

                RogueOfficer.Inventory.GiveNewWeapon("WEAPON_SHOTGUN", -1, true);
                RogueOfficer.Tasks.FightAgainst(Game.LocalPlayer.Character);

                while(true)
                {
                    GameFiber.Yield();
                    if (Game.LocalPlayer.Character.IsDead || RogueOfficer.IsDead)
                    {
                        break;
                    }
                }

                if (RogueOfficer.Exists())
                {
                    RogueOfficer.Dismiss();
                }

                GameFiber.Hibernate();
            });
        }
    }
}

3) The log:

Could you please just point out where to look? Thank you for your time.

 

 

Exception message: Operation is not valid because the specified  Rage.Vehicle is invalid.

 

at Rage.TaskInvoker.DriveToPosition(Vehicle vehicle, Vector3 position, Single speed, VehicleDrivingFlags flags, Single acceptedDistance)

 

In this particular case you tell a ped to enter a vehicle you spawned, but then also immediately afterwards tell the same ped to drive that vehicle to a position.

You didn't pass a vehicle to this method, which means it's defaulted to looking for the vehicle the ped is currently sitting in, which is null because the ped hasn't made it inside the vehicle yet. You added .WaitForCompletion() but then set the timeout to 3,000ms (3 seconds). So after 3 seconds it will stop waiting for the task to be completed and move onto the next line of code anyway.

 

Try setting the waitforcompletion to -1 (infinite)

Also, perform safety checks before executing tasks.

eg.

if(myVehicle.Exists())
{
	myPed.Tasks.EnterVehicle(myVehicle);
}

This way if the vehicle doesn't exist for whatever reason you won't instant crash your plugin.

Yeah, it was the "Rage.Vehicle is invalid" part that made my think of missing reference or some deep-seated issue with the code. What could be wrong with the vehicle on this point, I thought. You were right and I'm very grateful.

For the record I must admit that safety checks are really useful. For instance, when I tested the code again I learnt that If player somehow gets to your ped and kills him before he reaches the car the plugin will also crash unless check is in place.
