Camera / Aiming

We are creating a Light Gun game in Torque, similar to 'House of the Dead' and 'Time Crisis'. Basically this means the player's movement will be 'on rails' dictated by a path, while still being able to shoot. The shooting will be done with a mouse cursor which can be moved around the screen without changing the viewing angle.

We've been trying for some time to implement the aiming using information from tutorials such as the Click n Pick, Mouse controlled player movement (RPG Cam) and Turret & AITurret classes.

We think that we need to replace some of the firing code so that the projectile follows a vector from a casted ray (at the point on the screen where the mouse is clicked), rather from the centre of the screen (because the viewpoint won't be controlled by the mouse). Can this be done, either in engine or scripting, and how would we go about this?

For pathing the player, we have managed to use the AIPlayer class so that the player will follow a path. However, as far as we can tell, the player will only follow the path when you do not have control. For example, if you move to Fly mode (Alt-c), the player will follow the path, but when you take control again, he stops. Is it possible to take away the control of the player with the keyboard, but still be able to fire, and still look through the player's eyes? Are we going about it the correct way using the AIPlayer, or can a normal Player still follow a path?

This is how i've used AIPlayer at the moment:

%player = new AIPlayer() {
      dataBlock = PlayerBody;
      //dataBlock = DemoPlayer;
      client = %this;
   };

Many thanks, any help will be greatly appreciated.
