I want to simulate a restaurant mixing both, general and people model. My issue is that when sending the order ("comanda) to the kitchen, I use a separator for both boxes to mean different things. Box #1 - Box shaped: Will go to the kitchen and be processed as if it were the food. My main issue is with Box #2 - Cylinder: I want this to return to the tables called "comedor" and for this cylinder to join the box it matches when the box is out 'of the kitchen'. My main difficulty is trying to push (send) the cylinder from general environment and to pull (receive it) to the people model environment. I basically want the food to match the table that ordered it. .
