Anylogic: how to send order to specific agent?

Question

I am rather new at Anylogic and I have these populations of agents:

• Customer (parameters: name, latitude, longitude)
• Terminal (parameters: name, latitude, longitude)
• Order (parameters: Customer, Terminal)
• Truck (statechart to first moveTo order.terminal and then to order.customer)

For every different terminal (I have 5) there is a different order rate per customer. So, I created (within Customer) five schedules for the rate of orders for every terminal. Now I want to create an event in Customer to create orders (one event per terminal). I have this now for the terminial with the name terminalA:

Order order = new Order(this, terminal.name("terminalA"));
Truck truck = getNearestAgentByRoute(filter(main.trucks,
            v -> v.inState(Truck.Free)));
if (truck != null)          
    send(order, truck);

However, the part terminal.name("terminalA") does not work, as it can not be resolved to a variable. How do I create an order per terminal and tell Anylogic what terminal (with what name) it should create orders for?

Thanks in advance for your help!

Kind regards, Ella

You don't need to use terminal.name("terminalA"), just use terminalA if you have named that specific agent as terminalA; otherwise you need to access them by index, such as main.terminals(0). The parameter type inside the Order agent should be set to Terminal. For example, below I create an order agent with a lot of different parameters & variables, each with a custom type.

Edit. You also need to make sure that your agent list is not empty:
