I have a suggestion for controlling a 3D character using the XBOX 360 gamepad. The default settings for left and right thumbsticks are as follows:

left thumbstick up - walk/run forward
left thumbstick down - walk/run backward
left thumbstick left - move to left without turning body
left thumbstick right - move to right without turning body

right thumbstick up - look up
right thumbstick down - look down
right thumbstick left - look left
right thumbstick right - look right

My suggested settings:

left thumbstick up - walk/run forward
left thumbstick down - walk/run backward
left thumbstick left - turn to left
left thumbstick right - turn to right

right thumbstick up - look up and return to neutral when released
right thumbstick down - look down and return to neutral when released
right thumbstick left - look left and return to neutral when released
right thumbstick right - look right and return to neutral when released

It's set up so you can change it to however you wish.

I used the first setting (left stick move, right stick aim) because that's the default setting for every XBox FPS I can think of.

I disabled left thumbstick's X axis, "A" and "D" keys, and mouse look for now. I'm a little bit confused after looking at the code for controlling a 3D character. How do I assign the "look left" and "look right" commands to thumbstick's X axis, and "A" and "D" keys? How do I modify the "look" commands for the right thumbstick so that when I let go of the right thumbstick, the camera view return to neutral? There's "Walk-Through" template but it appears to be same as FPS templete because it uses the same "plBipedInput01.wdl" file.

It isn't easy to mix joypad and keyboard with the current template systems (t7 will included this).

Returning to neutral isn't supported yet either (not a feature I've seen in any modern FPS). But something to keep in mind.
