Also, has anything changed on this subject in the past 2 years?

Are there any recent tutorials or posts that you would recommend, that outline the best practice for doing secure transactions using the Facebook payment system communicating directly or indirectly with the SF extension or the database?

How does the extension communicate directly with fb? Or indirectly?

Awesome!

Thanks, your explanation helped.

I had my receiving function set up to receive SFSObject instead of Java Object, which was causing the function to not work.

I switched it to receive Java Object, then cast it to SFSObject, and it worked.

Hi Lappo Based on the OP question, I thought it might be possible to use a SFSObject for parameters, since you didn't say anything about it. The Manual indicates that handleInternalMessage() receives a String cmd and Java Object for parameters, but I have yet to find a single example of a Java objec...

How? I see a display in the admin tool under zone-->runtime zone settings, but no ability to select a room group

The only way I've seen so far is to restart the server, which I try to avoid doing...

Great! Thanks. I'm enumerating my commands so they're only 1 or 2 characters long, so that should also help.

Thanks Lapo! My concerns were based on topics such as this: http://stackoverflow.com/questions/16503735/is-number-comparison-faster-than-string-comparison But I assume there might be something going on under the hood of SFS2X that would make String comparisons as fast as int comparisons in this case.

I'm using handleInternalMessage to communicate between different game rooms. It seems to work fine, but I'm wondering if there is a performance hit given that I have to send a String cmd to the recipient extension, then check the cmd to see what it matches. To keep the match condition check fast, I ...

It would be nice if you could remove them though, just for the sake of organization. They show up in the admin tool and if there are a lot of "dead" ones cluttering up the dropdown isn't so nice, and also if you you have code that searches rooms by roomGroup, it would be nicer to not loop ...

This works for me:

So, there is no way to directly access a function within a room extension? You have to use "handleInternalMessage" and there is no other way? GameRoomExtension gameExt = (GameRoomExtension) room.getExtension(); Doesn't work to communicate because we're not allowed to cast ISFSExtension to ...

Thanks, I will use that in the future. I was able to stop all the Smartfox instances by restarting the machine, which one might not always want to do.

Today I tried to create a new zone using the admin tool and assign an extension to the zone. I find this always to be a dangerous thing to do as any little error and my SF won't restart... Although my extension shows no errors in eclipse, maybe the extension caused SF to fail to restart. I suspect i...

whats' the new url for that Lapo?
