I want to palletzing from rack. now, in my model, transporter pick whole pallet from rack.
But I want to make simulation that pick 4 boxes form one pallet.
Please help me.
The boxes are subnodes of the pallets. You are already assigning a reference to a box to "token.box" but then use "token.item" in the Load and Move Object activities. If you adjust those, the forklift will only load the box.
In addition you might want to a filter to the "Find Item" activity, so it only looks for pallets with at least one item them. Otherwise you will get an error when trying to load a box from an empty pallet.
The first "item" refers to the queried "Storage.Item" class object. The second "item" shifts the reference from the Storage.Item to the actual 3d object. "subnodes.length" then returns the number of objects/boxes inside that item.
Also note that you may not want to mark the pallet as outbound for it to be included in a second search, and consider that some additional effort may be required to manage virtualization of pallets and items if you need to use that feature.
The warehouse knows only slotitems. You need references to items on a packed pallet, then you do this by subnodes of this pallet, which is your slotitem.
Beware of once you took away first subnode and you take away a bit later second subnode, this 2nd node is then by runtime already third subnode.
