Anylogic: How to add a variable on agent based on a parameter of its upper agent?

Question

EX:

I have a population people with agent type Person with a parameter wrist_size.

In the agent type Person I've created another population =watches, agent type =Watch.

Now I want to create a variable in the lower agent type that will be based on the parameter of the upper agent.

length of the watch should be equal to the wrist_size of the person

What should code should I put to the variable?

Many thanks.

Answer 1

You can simply use people.wrist_size in the "initial value" field of Watch.length.

Each embedded population (here Watch within Person) gets a "link" up to their parent agent (here Person named people).
