Need help with parenting big contraption

Hello, I builded big ship out of many pieces and i am trying to parent it now. It looks like this -> So far i have managed to parent it so i can move entire ship correctly but i can only walk on that green area abov ship. What i want is to be able to walk on every piece… Sorry about my english too, i hope u understand me :stuck_out_tongue:

What is parenting anyway???

Don’t parent the pieces that you want to walk on or you will fall through them when it moves.

Btw is it possible to parent hydraulics ? I mean when i created simpel door with hydraulic and then parented that wall to another which had hydraulic attatched and when i moved it then door stayd in place and so did hydraulic

nothing ?
