I've been using the following to get the trunk door:

VehicleDoor[] doors = BombCar.GetDoors();
int door = doors.Length - 1;

This works fine if it's a 4 door car (sedan), but every other type of car returns an invalid door, is there another way to get this?

The doors don't incrementally count on a per car basis in the way you would expect. Try this, taken from one of the various natives:

doorIndex:
0 = Front Left Door
1 = Front Right Door
2 = Back Left Door
3 = Back Right Door
4 = Hood
5 = Trunk
6 = Back
7 = Back2

So can Car.Doors[5]  be null if it doesn't have a trunk? (which only has Back and Back2)

Yes, in the same way a 2 seater car wont have door indexes 2 and 3. They'll be invalid.

Is the array always going to have 8 items in it, though?

I'm not 100% certain to tell you the truth. Like I said the doors system seems to be the opposite of what you would expect.

I think that is the case if I remember correctly, but it's been a while.

It looks like it does, I just added a bool that's  true if vehicle.doors[5] != null, then open 5 and 6, seems to work until now

So, the array does always have 8 items in it; and if the vehicle does not have a specific door it is not null...

Array doesn't always have all doors, but something is very strange:

This is from a normal sedan:

[11/06/2016 00:28:27.958] LSPD First Response: Door 0: Rage.VehicleDoor
[11/06/2016 00:28:27.958] LSPD First Response: Door 1: Rage.VehicleDoor
[11/06/2016 00:28:27.958] LSPD First Response: Door 2: Rage.VehicleDoor
[11/06/2016 00:28:27.959] LSPD First Response: Door 3: Rage.VehicleDoor
[11/06/2016 00:28:27.959] LSPD First Response: Door 4: Rage.VehicleDoor
[11/06/2016 00:28:27.959] LSPD First Response: Door 5: Rage.VehicleDoor

this is from a cabrio (2seater)

[11/06/2016 00:29:32.825] LSPD First Response: Door 0: Rage.VehicleDoor
[11/06/2016 00:29:32.825] LSPD First Response: Door 1: Rage.VehicleDoor
[11/06/2016 00:29:32.825] LSPD First Response: Door 2: Rage.VehicleDoor
[11/06/2016 00:29:32.825] LSPD First Response: Door 3: Rage.VehicleDoor

but on the last one vehicle.Doors[5].Open works for some reason...Even if the array only has 0-3, [5] is never null

 

Edit: Fixed it for now by switching on VehicleClass to get which doors to open...ofcourse the second car that spawned was a space docker...ugh

Also, for some reason the backdoors on Vans are Vehicle.Doors[2] & 3. not as the natives reference states

^ And this is why SearchWarrant just opens all the bloody doors at once lol. Clearly whoever had the task of writing the door logic for GTA was on some interesting substances
