Messaging - AWS SimSpace Weaver

Messaging

The messaging API simplifies application to application communication within the simulation. APIs to send and receive messages are part of the SimSpace Weaver app SDK. Messaging currently uses a best effort approach to send and receive messages. SimSpace Weaver attempts to send/receive messages on the next simulation tick, but there are no delivery, ordering, or arrival time guarantees.

Use cases for messaging

Communicate between simulation applications

Use the messaging API to communicate between the applications in your simulation. Use it to change the state of entities at a distance, change entity behavior, or broadcast information to the entire simulation.

Acknowledge receipt of a message

Sent messages contain information about the sender in the message header. Use this information to send back an acknowledgement reply on receipt of a message.

Forward data received by a custom app to other apps within the simulation

Messaging is not a replacement for how clients connect to custom apps running in SimSpace Weaver. However, messaging does allow users a method of forwarding data from custom apps receiving client data to other apps that do not have an external connection. The message flow can also work in reverse, allowing apps with no external connection to forward data to a custom app then to a client.
