How to make the ASRS place items in the racks on both the left and right sides?

If I have two racks as different destinations, how can I modify the code to make the ASRS travel to either of the racks?

queue.setProperty("TransportRef", "Object current = ownerobject(c);\n\
Object item = param(1);\n\
int port = param(2);\n\
Object destination = param(3);\n\
double priority = param(4);\n\
int preempt = param(5);\n\
Object destination1 = current.outObjects[2];\n\
\n\
if (true) {\n\
TaskSequence taskSequence = TaskSequence.create(assertattribute(current, \"stored\", 0), priority, preempt);\n\
\n\
taskSequence.addTask(TASKTYPE_TRAVEL, current, NULL);\n\
taskSequence.addTask(TASKTYPE_LOAD, item, current, port);\n\
taskSequence.addTask(TASKTYPE_BREAK, NULL, NULL);\n\
taskSequence.addTask(TASKTYPE_TRAVEL, destination, NULL);\n\
taskSequence.addTask(TASKTYPE_UNLOAD, item, destination, opipno(current,port));\n\
string listName = \"TSList1\";\n\
List(listName).push(taskSequence, 0);\n\
current.centerObjects[1].message(0.01, current);\n\
}\n\
return 0;\n\
");

The "Use Transport" code you show here already gets the destination passed into it. You have to modify the "Send to Port" option of the queue because that is where the routing happens.

I see, but even though I have set the queue's "send to port" to "random port", it still only sends items to one of the racks.

It does send the fourth and fifth item to the other rack. But since that rack does not have the "Use Transport" option set the items move to the sink immediately.

Got it. Now I have another question. I have set the TransportRef for both racks, but the items placed on the rack in the front cannot be taken down. What could be the problem? (Originally, it was supposed to perform extraction or placement actions according to the 0, 1 array displayed in the output console.)model.fsm

The "bound" list field is only 0 if the load task happens at the first rack in the model. (Both racks have the same name, "Model.find("Rack")" will always find the first one.

I would suggest to set "bound" based on a label on the origin or destination object. Using names for such things will quickly lead to such errors when changes are made to the model.
