This fire is the whole point of the action.
currentDesired is the combined desired action from other actions
previously processed by the action resolver. In this case, we're
not interested in that, we will set our desired
forward velocity in the myDesired member, and return it.
Note that myDesired must be a class member, since this method
will return a pointer to myDesired to the caller. If we had
declared the desired action as a local variable in this method,
the pointer we returned would be invalid after this method
returned.
