If I have a list of participants that the agent should be expecting, how can I wait for for them to join before doing anything
t
Thanks for reaching out, Nathan. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
If you want to wait for a list of participants to join before moving forward, here are a few ways you can do it, depending on what fits your needs best: • Synchronous Approach: You can use 
ExpectRoomWithParticipants
to keep checking the room’s participant list until everyone expected has joined or a timeout happens. This works great if you’re testing things out. • Asynchronous Approach: Try 
wait_for_participant
to wait asynchronously for participants to show up. This is handy when your app needs to react as soon as someone joins. • Wait for Active Participants: Use 
waitUntilActive
to make sure participants are actually active after joining — super important if you’re dealing with audio or video playback. If you’d like a hand with any of these, just let me know what you’re working on or which programming language you’re using, and I’ll happily guide you through it!

python agents sdk, do async approach
t
To get started with the asynchronous approach using the Python Agents SDK, you can use the 
wait_for_participant
method to patiently wait for participants to join. Here’s a quick example:
Copy code
participant = await ctx.wait_for_participant()
print(f"Participant {participant.identity} joined")
This method will wait until the first participant joins the room and then give you their details. If you’re expecting a few participants, you can loop through your list and wait for each one to show up like this:
Copy code
expected_participants = ["participant1", "participant2"]
joined_participants = []

for expected in expected_participants:
    participant = await ctx.wait_for_participant()
    if participant.identity in expected_participants:
        joined_participants.append(participant.identity)
        print(f"{participant.identity} has joined")

if set(joined_participants) == set(expected_participants):
    print("All expected participants have joined")
Feel free to reach out if you want me to help with anything else or tailor this to fit your specific needs!
