Question

I created a function to move agents from my population (database) into a process.

Somehow it throws an Error

Exception during discrete event execution:
root.<population>[0]:
This agent isn't located in any space

The goal of my model is that transporters arrive at certain arrival times (the same date as in the model) from a dataset in my factory:

My steps until now:

1. Create a population with agents of the type of my agents and fill them with the values of my data

2. create an event which checks every minute for all objects of my population if their arrival time equals the models time

3. Write a function that enters them into my process and on the road to come to my factory

Therefor every transporter exists already before being entered into my process so that the event can check the condition.

My problem: When the condition is true and the object should enter my process an error occurs:

Exception during discrete event execution:
    root.<population>[0]:
    This agent isn't located in any space

I don't understand why they dont have their initial space already. I tried to set the space on the enter block with agent.setSpace(getSpace()) but nothing changed. My population is also in the main method Properties of pop:

properties agent:

Answer 1

Agents are not data. They need a space. By default, it is the space of the ebmedding agent of their population (typically Main if the population is on Main ).

If your Enter block is not in the same agent as the population was beforehand, you need to call agent.setSpace(getSpace()) in the "on enter" code box of the "Enter" block.

This should assign the agents to use the new space of the embedding agent
