Anylogic How to queue and process received messages by agents

--This post has been edited as @Benjamin has suggested in his answer

I am trying to model peer influence for churn situations. Agents will send messages to their peers depending on different conditions. I have also created a List called MessagesReceived to store received messages.(The number of these messages may be >1).

I have tried processing (i.e. adding the message to a list of received messages) these messages in Connections>OnMessageReceived but although I can access message and sender objects, I don't know how to access the receiving agent there.

what would you suggest in this case?

P.S: variable names and types may be a little different in screenshots but the problem I described here does not come from that.

Please always only ask one question per issue, else it gets too confusing.

So let me answer your first question:

although I can access message and sender objects, I don't know how to access the receiving agent there

You can simply type this. in the code box below and you have access to "yourself". In fact, you do not even need that, simply access the fields from "yourself" here. If you are in an agent with variable myVar, you simply use that.

For the other questions, please open separate issues, see this.
