Example of an MMO-style third person camera and movement system.

All movement is relative to the current view. Any movement keys may be combined.

W - Move forward
A - Strafe left
S - Move backward
D - Strafe right

To rotate the view, hold down the right mouse button and move the mouse. You can also move while using mouselook.

Movement is implemented by calculating a velocity vector in object-space for the player based on whatever keys are currently pressed and then converting it to polar coordinates, and concatenating the resulting angle with the camera angle to get a movement direction in worldspace. Periodically (every 50 ms in this demo) a target point is calculated by extruding the unit's current position on the direction vector, and the unit is issued an order to move to that point.

Feel free to use this in your own maps, the entire system is modular and you can actually just copy & paste the triggers to add this to any map. All you need to do is call the "Assign Player Control" function to give a player direct control over a unit.
