-These two components nicely work in tandem if they both exist: cgeref:TCastleWalkNavigation[] allows to move / rotate by dragging anywhere on the screen, while cgeref:TCastleTouchNavigation[] allows to move / rotate by dragging the special gizmos in screen corners. We recommend in this case to _disable movement using cgeref:TCastleWalkNavigation[]_ because movement using cgeref:TCastleTouchNavigation[] is more precise and then user can use the screen only for rotating (like aiming, in shooting games), without moving by accident. To achieve this, set cgeref:TCastleWalkNavigation.MouseDragMode[] to cgeref:mdRotate[].
