Ai not spawning...

Hey,
I'm trying to get an Ai controlled vehicle into my game, but it doesn't seem to be working. Here's the modified parts of the aiplayer.cs file(all I did was modify it to use a vehicle datablock instead of the player one; I'm using the starter.racing as the basis for my game):
//-----------------------------------------------------------------------------
// Demo Pathed AIPlayer.
//-----------------------------------------------------------------------------
datablock WheeledVehicleData(DemoPlayer : DefaultCar)
{
shootingDelay = 2000;
};
//-----------------------------------------------------------------------------
// AIPlayer static functions
//-----------------------------------------------------------------------------
function AIPlayer::spawn(%name,%spawnPoint)
{
// Create the demo player object
%player = new AiPlayer() {
dataBlock = DemoPlayer;
path = "";
};
MissionCleanup.add(%player);
%player.setShapeName(%name);
%player.setTransform(%spawnPoint);
return %player;
}
function AIPlayer::spawnOnPath(%name,%path)
{
// Spawn a player and place him on the first node of the path
if (!isObject(%path))
return;
%node = %path.getObject(0);
%player = AIPlayer::spawn(%name,%node.getTransform());
return %player;
}
function AIManager::spawn(%this)
{
%player = AIPlayer::spawnOnPath("Bubba","MissionGroup/Paths/Path1");
%player.followPath("MissionGroup/Paths/Path1",-1);
//%player.mountImage(CrossbowImage,0);
//%player.setInventory(CrossbowAmmo,1000);
return %player;
}
I have a Path names "Path1" under "Paths" in the mission editor, and iIve double checked the datablock, yet no car spawns in my game.
???
Thanks,
Lane

Yes, and I see none. And heres the car Datablock(with the shapefile def) just in case theres something wrong I'm missing:datablock WheeledVehicleData(DefaultCar)

Ummm, correct me if I'm wrong but isn't AIPlayer dependant upon PlayerData?

I don't think %player would work for vehicles it would probably be %wheeledvehicle maybe, thats not very specific though.

What you can do is create an AIPlayer and MOUNT it to a vehicle. This is discussed on This Resource

It won't work that way. An AIPlayer is an object that derives (inherits) from Player. A vehicle is another branch of the tree. You can't just create an AIPlayer and set it to a vehicle datablock.What you can do is create an AIPlayer and MOUNT it to a vehicle. This is discussed on This Resource

You could probably also create an AIPlayer datablock and just set the shapefile to your car.dts

Wouldn't that prevent any wheels from being automagically created?? Because any wheeledVehicle.dts wouldn't have the wheels attached until code takes over...?!? Bruno's got the right idea...

Thanks for the link Bruno, looks like that's what I'll need.

@Rex, Personally I would just mount the wheels in code at creation, just like you would mount a weapon.

But you still wouldn't have the physics. The resource isn't that hard to implement and it solves most of the problems.

Off the top of my head, I don't see a shapeFile definition in your datablock, although it -may- be in your DefaultCar datablock.
Also, you are dropping in a wheeled vehicle into AI code designed for a playerData type object. There may (or may not!) be issues involved with that as well.
