Hi TestDemo,
Greetings!!!
Yes, you can Broadcast message to all users when you called sendMove function. As sendMove API works inside a room. You can call sendChat API through which you can message all the room users.
It depends on you when you want call either by calling ith after sendMove or after when you receives success callback in onSendMove done.
So you need to write your own logic for broadcasting the message automatically when sendMove() gets called, but in AppwarpS2 advance version of AppWarpCloud you write your own business logic by overriding the AppWarpCloud features.
Let me know if more queries are concern.
Thanks
