[plugin] firebase

Is it possible to create a multiplayer lobby with rooms using your firebase plugins? May be lobby could be just a C2 object which is monitored on firebase server and rooms are items? I'm trying to figure out how to implement it.

Here is a demo of lobby and rooms. And Capx file1. Capx file2 - chat room only.

I had not finished these documents.

That's great, man - thank you!

Following question:

Data get pushed to the firebase, but there's a weird randomly generated key like that "Ji29D5OOCXw8DoQe98_:" on top of each message. Is it possible to disable it or set this key manually?

Ah, ok - it's possible to set manual key with "Set Value" method

A small feature suggestion for the firebase "query" plugin:

• pick random dataset from the set query
• or maybe pick dataset by expression

Firebase does not support random picking directly. User needs to fetch all items then picking in local. But this solution might not efficient since it fetch all items back.

So that I made another plugin for picking with conditions (expression) - rex_firebase_itemfilter, it saved each key of item and the properties into individual nodes. Call "Action:Get random items" to get keys of random items (dataset), then fetch these items by keys in other plugin like rex_firebase. (rex_firebase_itemfilter only used to get keys)

There is another rex_firebase_itemtable for storing item (dataset) in 1d hash table.

Cool, I will try that.

Querying feature is the weakness in firebase, although firebase had added more functions in querying.

So my sloution is firebase (for real-time) + parse (for static data), it is another story...

Interesting, I will try parse for static data.

My team member uses firebase+parse for server programming in C2.

Arne had made a parse plugin. And I had made another different one (but the document had not ready).

BTW, there are many back-end solutions today, firebase and parse are only two of possible solutions.

I think it could work very well for turn based games or async multiplayer. But what is with real time action games like shooters/mobas/rts? I think the lag is too large or may be it's possible to solve that with plugin which will calculate all that complicated stuff like collision prediction, interpolation etc.

Sorry, I did not have plan to do this.

It might be better to use another solution like official MP plugin for these kinds of application. Here is another possible solution - photon cloud.

rexrainbow

thanks for pointing me out to photon cloud plugin. I might consider it for real time multiplayer projects.

If you're making a real time multiplayer game, I strongly suggest using the official mp plugin. It connects the players directly to each other. Use cloud storage for slow/turn-based games and storing information like points and profiles, etc. You'll use up your bandwidth in no time and wont be able to grow your userbase.
