Ambit,
JCL has some Chase cam code that works with the current beta releases. With it, all you would have to do is compute the position of the camera.

Cameras can be a little bit tricky, because if you use the typical method of pointing a camera at a player, (by subtracting the two position vectors and then using vec_to_angle) and the camera points down more than 90 degrees, the view appears to spin at various speeds until it comes to rest at the angle it was looking for. This makes the camera act unprofessional at best, and nauseating at worst!

Position can be found by taking a vector for the distance of the camera to the player, and doing a vec_rotate on the value for what a angle you want the camera to appear at and then adding that displacement to the players position.

Good luck!
