Sending Messages

Agents send messages by adding JSON objects to their messages array. The object is defined as:

{
    to: "string" //an agent_id or agent_name
    type: "string" //a string that defines the type of the message
    data: {} // an object that serves as the payload 
}

• to: An agent id or an agent name. The agent with the corresponding agent_id field or the agent(s) with the corresponding agent_name field will receive the message in the next time step.

• type: A user defined string that serves as metadata for the object, describing the message and/or its purpose.

• data: A user defined object that can contain any arbitrary data.

const behavior = (state, context) => {
    let messages = state.get("messages");
    
    messages.push({
        to: "people", 
        type: "greeting", 
        data: {"msg": "hello"}
    });
    
    state.set("messages", messages);
}

messages = state.get("messages")
messages.append({"to": "people", "type": "greeting", "data": {"msg": "hello"}})
state.set("messages", messages)

state.addMessage("people", "greeting", {"msg": "hello"})

state.add_message("people", "greeting", {"msg": "hello"})
