How can I set the parameter of an agent when it is created in a source block?

In my case I create agents of type "Pallet" in the source block. This agent has a boolean parameter "Tracker". The assignment of the trackers should be random, but follow a certain coverage of the trackers. In the end I want to perform a Parameter variation experiment where I want to vary the coverage of trackers.

I tried various ways to access or set the agents parameter: self.Tracker, agent.Tracker, pallet.Tracker but none of them work, throwing different error messages.

I know this is not SOF style but if it is answered easily I would appreciate another hint on: How can I access the parameter later on, i.e. in queue blocks or so, to see how many agents with which parameter value are in the blocks?

No, you still create generic agents, see your properties. You need to select "Pallet" in the "New agent" dropdown.

Only then do you have access to its parameters. You can set them in the Source block's "on at exit" using agent.set_MyParam(yourValue);

Or you use the population, where Tracker is already waiting for what it should be.
