Reflectors are stateless, public, message-passing services located in the cloud. When a reflector receives an event from a user, it mirrors it to all the other users in the same session.

Your API Key gives your app access to Croquet's reflectors, as well as to Croquet's file servers for storing Snapshots.

There is a single reflector allocated for each session. All it does is bounce events generated by one peer in the session to all peers in the session, adding a time stamp. It also sends out timestamps automatically to advance computation time if there are no other events. In Microverse you can shift-click the QR code to see the message latency (there is currently a bug where you may have to shift-click on the border of the QR code instead)

Files are served via Google CDN (that is model snapshots, or files you drop into your world – they get encrypted, hashed, and uploaded so they can be efficiently cached). And we operate reflectors on every continent except Africa and Antarctica currently.
