Hey @Twan_so-kl
I am assuming your are only using blueprints for this case.
For navigation the easy way is to use the navigation details in the widget panel
Here a little example of what you can do with navigation.
About direct input you can work it in many ways.
Pass the input from the character or just add it in the widget.
Remember you need to have game and ui or game ui modes to support the inputs.
