forgot to say thanks for this. Got it working after a period of fumbling in vizconnect.
For the record
- in the 'inputs' section, add a joystick
- In the Transport section, add a new one and select 'walking'
- Click the mapping icon for the new walking transport and for each action
- If your joystick has a slider, then make sure its in a central position (reading zero) before you continue
- from the drop down select joystick (instead of keyboard)
- Hold the joystick in the desired position (eg pushed forward) and click the button to the right hand side to assign the input signal
- repeat for all the mappings you want to set
- Apply and Exit
- Make the new walking transport the default one
- in the scene graph on the RHS drag the root of the tree just below the old 'main_transport' and drop it under the new walking transport
- test it by using the joystick to navigate around the piazza that vizconnect autoloads
- save your new vizconnect file
