this is by no means an advanced 3rd person camera script, but should get you started with the camera stuff. Any questions can be mailed to:

controls:
- just moving the mouse turns the player (and the camera)
- moving the mouse while holding the left button turns the camera
- turning the mouse wheel adjusts camera height
Here it is:

}
}
to use, include this file and do this in your main script:
Code:
function main()
{
load_level("your_level.wmb");
camera_init();
wait(1);
}
action your_player_action
{
player = me;
control_cam();
}
Use it freely, credit is not needed but will be appreciated
