intercepting chat messages

[jkeller]

Hi! I'm trying to create an extension (for 5E) that redacts certain text from messages. Specifically, it's for table roll results, but I think any messages would be fine.

I've tried overriding deliverChatMessage. When I roll on a table, that function gets called multiple times (once for the table name, once for each column); that's fine. But it gets called where the roll was made; or at least, that program's console is where I see my trace messages (via print).

I want to treat the message differently (for the DM/host vs the players/clients). In other words, I want the host to see the unredacted messages, but the clients to see the redacted version.

I can't figure out what I should be overriding.

Thanks!

deliverChatMessage is a built-in core API of FG, so not something you want to override.

You might be able to use this kind of call used by the sound triggers:
ChatManager.registerReceiveMessageCallback(Soundse tManager.handleChatMessage);
and then do whatever you need to do to the data.

Thanks! I'll try that approach.

So using registerReceiveMessageCallback is closer. It does get called on both the host and client.

It has access to the chat message, but I don't see anyway to change the message. Is it only pass-by-value, or is there some way I could change the message before it gets displayed? Thanks!

Ok, so I can return true to disable the message display, and then change the local copy of the message, and send that.

That works - but only for the table name message. The table data is somehow sent/processed separately. It doesn't seem to be part of the rMessage sent to my handler.
