Simple AI Vehicle AIWheeledVehicle

This would not be possible without Badguy's getSteeringAngle function!

Code archive mirrored here:
http://knowhere.net/gg/aiwheeledvehicle.zip

Steps:

1. Add AIWheeledVehicle.cc and AIWheeledVehicle.h to your torque project.
Copy the files to the engine/game/vehicle directory.

2. In Vehicle.h:

After:
void renderMountedImage(SceneState *state, ShapeImageRenderImage *image);

But before:
public:

Add this line:

virtual bool getAIMove(Move* move);

The full block should look like this:

void renderMountedImage(SceneState *state, ShapeImageRenderImage *image);

	virtual bool getAIMove(Move* move);
public:

3. In Vehicle.cc:

In Vehicle::ProcessTick after:

Parent::ProcessTick(move);

Add (this is equivalent to the code in player.cc):

// If we're not being controlled by a client, let the
   // AI sub-module get a chance at producing a move.
   Move aiMove(NullMove);
   if (!move && isServerObject() && getAIMove(&aiMove))
      move = &aiMove;

At the end of the file, add this block:

//
// AI stuff
bool Vehicle::getAIMove(Move* move)
{
	return false;
}

4. Recompile the engine.

5. Copy the bot.cs into the server/scripts/ directory of your game.
Add this line to server/scripts/game.cs:

exec("./bot.cs");

6. Finally, to create the bot, add this line to your onMissionLoaded function
in server/scripts/game.cs:

$Bot = CreateAIWheeledVehicle("MasterBlaster", "MissionGroup/TrackPath");

TrackPath is the name of a path you've created with the mission editor. See the
bot path finding tutorial listed in the link above for info on how to create that.

Hope this helps!
